2 Tips on mounting and installation 2.1 General safety tips The meters are to be used exclusively for measuring electrical energy and must only be operated within the specified technical data (see nameplate). When installing or changing the meter, the conductor for which the meter is connected must be de-energised. For this purpose only the provided terminals must be used. to parts under voltage is extremely dangerous; therefore the relevant backup fuses are to be removed and stored so that other people cannot insert these unnoticed. Before opening the meter, the secondary circuit to the current transformer must definitely be short circuited. The high voltage on the current transformer is extremely dangerous and destroys the current transformer. With an incorrect installation of the meter, the S0 inputs can lead to mains voltage. Caution: danger! The local standards, guidelines, regulations and instructions are to be obeyed. Only authorised, trained personnel are permitted to install the electricity meters.
2.2 Maintenance- and guarantee tips The meter is maintenance-free. With damages (e.g. caused by transportation or storage) no repairs may be carried out. Once the meter has been opened, all warranty claims cease. This also applies if a defect can be traced back to external influences (e.g. lightning, fire, extreme temperature- and weather conditions, incorrect or careless use or treatment).
12
2.3 Mounting Meters from the series LZQJ-XC are suitable for wall mounting according to DIN 43857-2.
Figure 1: Dimensions
13
2.4 Installation When connecting the meter it is very important to take notice of the circuit diagram which you can find on the inside of the terminal cover and also in the delivery documents. In chapter 2.6 Circuit diagrams on page 16 you can find examples of these.
2.4.1 Transformer operated meter Meters for transformer operation are to be protected with a back-up fuse of < 10 A in the voltage path.
Figure 2: Back-up fuse with transformer operated meters
2.4.2 Direct connected meter Meters for direct connection are to be protected with a back-up fuse of 100 A.
Figure 3: Back-up fuse with direct connected meters
14
Installation check After installation of the meter, it is possible to check if it has been connected correctly by means of the function “Installation check“ in the EMH-COM/COMBIMASTER 2000. This function is not a standard part of the EMH-COM/COMBIMASTER 2000 program, however, can be ordered as an additional module. Open “Readout“ > “Installation check“
The graphic installation display shows the current network behaviour. In the table the current values of phase L1, L2, L3 and also the sum of all phases are shown.
Further information can be found in the manual EMH-COMBI-MASTER 2000.

2. The battery status display shows the charging status of the buffer battery of the real time clock. The following displays are possible: = full voltage, real time clock is buffered when there is no voltage = discharged, no buffering of the real time clock is possible 3. The communication display is continually lit-up when there is communication with the meter via data interfaces (optical or electrical) or the display flashes when the parameterisation status is active. 4. The phase display signalises connection of the individual phase voltages. With an incorrect rotating field all three symbols flash. 5. The unit is displayed corresponding to the measured energy type or the displayed measured value. 6. In the additional cursor field, operation conditions of the meter are represented. The black arrows show if a manipulation or an installation error has been ed or if the performance threshold has been exceeded. MAN
The cursor is active if a manipulation has been ed on the terminalor meter cover or electromagnetic interference.
INST
The cursor is active if an entry has been ed in the installation check .
PWR
The cursor is active if a power threshold set in the meter is exceeded.
7. In the standard cursor field, operation conditions of the meter are represented. The black arrows show which tariff and maximum demand is active and via which hardware (clock or ripple control receiver) the meter should be controlled. T1-T4
Tariff information for energy. All tariff s which can be activated are displayed on the nameplate.
M1-M4
Tariff information for maximum demand. All tariff s which can be activated are displayed on the nameplate.
RCR
The cursor flashes when the internal RCR is activated and ready to receive. The relevant cursor is continually active when the internal ripple control receiver receives a telegram.
RL
The cursor flashes for the duration of the activation of a reset inhibition.
CLOCK
The cursor is active if the internal clock controls the tariff device.
SET
The cursor is active when the meter is in the set mode.
8. In the value area the measured values are represented. 9. In the OBIS code area the measured values are defined by means of the OBIS code. The display is capable of displaying the long OBIS code (see page 91).
31
3.3.2 Test - LEDs The Test-LEDs are used for the output of energy proportional active- and reactive energy impulses, for certification of the meter and for the display of start-up and no load operation. The impulse constants depend on the meter type. If the meter measures no current or current below the start-up threshold, the meter is in the no-load operation mode. In this case, the LED is continually lit-up. With Combimeters the LED is continually lit-up if the energy flow direction is negative. If the meter measures current above its start-up threshold, energy proportional impulses are displayed.
3.3.3 Call-up and reset button The call-up button serves to call up the display lists in the display. Via the reset button, which is situated behind the sealable module cover, a manual reset can be carried out.
3.3.4 Optical call-up sensor The optical call-up sensor serves to call up the display lists in the display. Operation of the display takes place by means of a pocket lamp.
3.3.5 Parameterisation button The parameterisation button is used to activate the parameterisation status in the meter. The button is located under the meter cover. To operate this button the meter must be opened which means the seals must be broken. Breaking the seals means that the certification expires and therefore this may only be carried out by authorised personnel. When the meter is in the parameterisation status the communication symbol flashes in the display.
3.3.6 Optical data interface D0 Communication between the meter and PC takes place via the optical data interface. An optical communication adapter OKK is required for this. In order to fix the OKK to the meter there is a magnetic ring which is found on the meter cover. Further information on the optical data interface can be found on page 40.
3.3. Meter cover The meter cover is made of crystal clear polycarbonate. The housing cover is mounted at the bottom in the baseplate and screwed at the top with both of the sealing screws. With the relevant configuration, when removing the housing cover, a manipulation is ed. More detailed information can be found on this in chapter “6.1 Manipulation” on page 76.
32
3.3.8 Sealable terminal cover The terminal cover is made of grey polycarbonate and is fixed to the terminal block with sealing screws. The circuit diagram is fixed on to the inside of the terminal cover. With the relevant configuration, when removing the terminal cover, a manipulation is ed. More detailed information on this can be found in chapter “6.1 Manipulation“ on page 76.
3.3.9 Battery compartment The battery compartment is found under the sealable module cover. A lithium battery (CR-P2, 6 V) can be assembled here which, if necessary, can be exchanged. The battery is used for reading out the meter via the optical interface and for reading the display during power failure. It also buffers the real time clock. In the delivery status the battery function is not active. To activate it, open the hinged cover and pull out the readout battery. Then remove it from the holder and flip it over so that the battery s to the compartment. Afterwards push the battery incl. folder in the battery compartment with the s of the compartment facing left. Finally close the hinged cover.
3.3.10 Communication module compartment The communication module compartment is found under the sealable module cover. Here a modem- or interface module can be inserted. Mounting and removal can take place when the meter is under voltage. Further information on the modules can be found on page 17 and also in the LZQJ accessories catalogue.
3.3.11 Nameplate The nameplate contains data for identification of the meter, the approval mark, technical specifications and explanations. The cursor lettering below the display and the description of the OBIS code on the nameplate are standard and not adapted to the meter version. The nameplate can contain more information than is configured on the existing version. The parameterised functions are to be taken from the list of desied features.
3.3.12 Transformer nameplate Transformer operated meters (in general secondary meters) are equipped with a transformer nameplate which is found under the sealable module cover. On the transformer nameplate the following information is displayed:

Switched-mode power supply Measuring device Tariff device Interfaces In- and outputs
In the following the most important modules are described.
3.4.1 Voltage supply 3.4.1.1 Direct supply The LZQJ-XC is supplied via a primary switched, long-range power supply (3x58/100 V ... 3x240/415 V) with a high degree of efficiency. The power supply is “earth-fault proof“ and guarantees operation without the neutral conductor (N). In case a component fails during operation the power supply is overload- and short-circuit-proof.

3.4.1.2 Auxiliary voltage Only valid for LZQJ-XC-P2 ... and LZQJ-P5 ... (precision meters with accuracy class 0.2 and 0.5)! The LZQJ-XC as a precision meter has the possibility of external auxiliary voltage supply. In general there are two types of supply which are differentiated between: a) Auxiliary supply The energy for the electronic measuring device is only taken from the auxiliary supply. The auxiliary supply and measuring circuit voltage are galvanically separated. b) Combined supply With certain voltage conditions the power for the electronic device is no longer taken from the auxiliary supply, instead, it is taken from the measuring circuit voltage. If the auxiliary supply completely fails, the power for the electronic measuring device is taken exclusively from the measuring circuit voltage (feature of the combined supply). This means, the meter is completely capable of functioning even if the auxiliary supply fails (advantage when compared to option a)). The presence of auxiliary voltage supply relieves the load in the voltage paths in the measuring system, resulting in a substantial decrease in apparent power consumption (see Table 10).

3.4.2 Measuring device 3.4.2.1 Measuring principle The electrical energy is measured by processing the sampling values which the Analog Digital Transformers (ADC) send to the processor. By means of this, all of the measured values can be measured or calculated in all quadrants. The calculation ensures that the values are stable and resistant to ageing.
Figure 16: Definition of quadrants
3.4.2.1.1 Voltage measurement The terminal voltages create network proportional internal voltage levels at internal voltage dividers. These are fed into the 3 input channels of the ADC.
3.4.2.1.2 Current measurement For measuring current, error compensated current transformers are used. The output variables of the respective amplifier are fed into the 3 input channels of the ADC.
35
3.4.2.1.3 Data protection During operation the current measurements are stored in the working memory (RAM). Every 24 hours this data is transferred to a non-volatile memory. It is only in cases of longer interruptions that the measuring period is interrupted and the device completely shuts down. Data remains stored in the non-volatile memory for at least ten years. No buffer battery is needed to preserve the data. The data retention is assured exclusively by the qualities of the storage medium (Flash).
3.4.3 Tariff switching clock The tariff switching clock is integrated into the meter. It is based on a quartz-controlled, battery or capacitor-buffered real time clock (RTC) which provides time information (date, day of week, time) in second intervals. Switching times can be configured exclusively for the customer by means of: −
16 season tables,
− −
16 day types or 384 holiday definitions for any weekdays
These switching times are compared continually with the real time clock. If they coincide with the configured switching times or switching periods, the switching function is activated. Switching functions are the activation of the maximum demand s and energy s. As a result of this, 32 energy s and maximum demand s each with a maximum of 8 tariffs can be configured via the tariff switching clock. At the beginning of the summer period an hour is added on to the time of the tariff switching clock (CET). The beginning and end of the summer period is determined with the help of a summer time . This is settable in order to be able to react to possible changes of the current valid summer time regulations. The accuracy of the real time clock is within ± 5ppm. The buffering of the real time clock (RTC) can take place by a SuperCap-capacitor with a running reserve of approx. 6 days (150 hours). With a completely discharged SuperCap the charging time is approx. 18 min after applying the voltage phases (90% voltage). Instead of a SuperCap-capacitor, the buffering can take place by using a battery (dry Li-battery) with a running reserve of > 20 years. The latter is recommended for meters with load profile memories so that the load profile is correctly dealt with chronologically when there are longer power interruptions or if the meter has been turned off for longer periods. As a rule, the real time clock is quartz controlled however, can also be synchronised via the following variations: − Synchronisation of the real time clock via the line frequency The clock is synchronised cyclically by a mains frequency controlled timer −
Synchronisation of the real time clock via an impulse at the input Synchronisation takes place at o the next full 1 minute or o next measuring period limit or o a fixed time of the day
−
Synchronisation of the real time clock via a DCF77-receiver connected to the S0-input DCF77 is a time signal which is emitted via longwave. The circulation is carried out by the PTB and serves as the legal time. In the DCF77 signal, time information of the next complete minute is coded to which the meter then synchronizes itself.

3.4.4 Ripple control receiver (RCR) The integrated rippple control receiver of the LZQJ-XC is based on a highly selective recursive filter which directly processes the16 bit sampling values of the AD-transformer. Due to the sampling rate of 3200 Hz, ripple control frequencies in the range of 110 to 1600 Hz are ed. The following telegrams can be configured. − − − − − − − − −

The telegrams differ by their command evaluation procedure and by their digital structure of the pulse sequence. The ripple control receiver can switch 6 ripple control relays which are available for control functions of the meter. Also tariff- and maximum demand controls, resets and caution signals can be ed on directly via terminals or optical fibre interfaces. Reading out and setting of the RCR position of the ripple control receiver Open “Direct“ > “RCR position...“
After activation of the menu option, the relay position of the ripple control receiver is read out first of all. Next a window opens in which the relevant relay position is marked with an “X”. The relay position can be changed by means of a double click on the appropriate field. To send the changed settings to the meter click on “Write“.

3.4.5 Data interfaces Data exchange between meters and readout devices (eg. PC, modem, PDA, etc.) takes place via the optical interface (D0) or, at auxiliary terminals, via the electrical interface (RS232, RS485, CL0). Communication is in accordance with DIN EN 62056-21 or DLMS. 3.4.5.1 Optical data interface D0 Communication between the meter and the PC takes place via the optical data interface. For this an optical communication adapter (OKK) is necessary which can be obtained from EMH. The OKK is available for connection to a readout device with a RS232-, USBor Bluetooth interface. It has a magnet to fix it to the iron ring situated on the front of the housing cover. Transmission rates from 300 to 9600 Baud, fixed or mode C/E can be set.

Simultaneous operation of the first electrical interface and optical interface is not possible. In addition to the above listed interfaces a modem- or interface module can be mounted in the communication module compartment. By means of this it is possible to grant third parties restricted access to the meter data. The first interface can be used in parallel by the utility company for meter communication with access to all data. By means of a multilevel concept, the access rights can be easily assigned.

It is a ive two-wire interface which means that it does not have its own power source. The data is transmitted by electric current / no electric current (Mark/Space) at a nominal current of 20 mA which is the reason why the CL0 interface is also referred to as the 20 mA current interface. The CL0 can be found at the auxiliary terminals 23 (+) and 24 (-) in accordance with the VDEW-Specifications 2.1.

3.4.5.3 Optical fibre interface LLS At the meter terminal L there is a coupling point to which an optical fibre can be connected by simply plugging- and screwing in. The other end of the optical fibre is plugged into the optical fibre separation box. The optical fibre interface can be found at the auxiliary termnal L.
Figure 24: Connection diagram - LLS
The optical fibre separation box is in DIN-Rail housing according to EN 50 022 and it has its own optical fibre output so that a total of four relay boxes can be cascaded.
Figure 25: Connection plan - LLS
For each relay box up to 6 control outputs can be realised, altogether a total of 24 control outputs. Each output of the optical fibre separation box can be designed as a relay(optional with suppressor circuit) or Opto-MOSFET output or as a make- or break . The optical fibre separation box is supplied by a long range network power supply from 100V to 230V. A complex input suppressor circuit protects the meter from destruction as a result of bad power supply. With the described arrangement, an optimal isolation is obtained by means of galvanic separation of the optical fibre between the meter and relay boxes. Features Number of connected boxes

3.4.6.5 Important tips for mounting and installation Safety tips The communication modules are electronic appliances and may not be used for any other purposes. Mounting may only be carried out by electronic specialists according to the generally recognised codes of practice and according to the standard requirements for the installation of telecommunication systems and devices. Before assembly, please examine the communication module for any exterior, obvious transport damages and on location check the electrical operating conditions. Mounting can take place under voltage. The communication module should be stored, used and transported in a way so that the pins cannot be damaged. Assembly of the external aerial with GSM- and GPRS modules When assembling the exterior aerial (which is available as an optional accessory) the assembly fixing bracket must be earthed against lightning by a specialist! Inserting the SIM card in the GSM- and GPRS modules Only insert the SIM card when the appliance is switched off! Maintenance- and guarantee tips The communication module is maintenance-free. With damages (e.g. caused by transportation or storage) no repairs may be carried out. Once the meter has been opened, all warranty claims cease. This also applies if a defect can be traced back to external influences (e.g. lightning, fire, extreme temperature- and weather conditions, incorrect or careless use or treatment).

4 Firmware Diverse configurable variables have been programmed in the meter which define the meters functions. These include: − −
settable variables parameterable variables
Settable variables can be changed by operation buttons or one of the interfaces. Parameterable variables include variables which define the properties of the counter. Parameterable variables can be changed via the optical interface D0 or one of the electrical interface. To do this, the meter must be in the parameterisation status (by pressing the parameterisation button). To operate the parameterisation button, the meter cover must be opened which means that the seals must be broken. Breaking the seals means that the certification is no longer valid and may therefore only be carried out by authorised personnel. When the meter is in the parameterisation status only the communication symbol flashes. The parameterisation status is ended by means of the following: − −

4.1 Tariff device The tariff device calculates the consumed or supplied electrical power or energy on the basis of the digitalised measured values and allocates it to the power and energy s.
4.1.1 Energy- and maximum demand tariffs With the LZQJ meter, a maximum of 32 s each can be configured for electrical energy and maximum demand. Each has a memory with up to 15 pre-values which represent the measured values and the time stamp of the last 15 reset periods. The assignment of the measured variables is configured at EMH according to the customer’s requirements. 4.1.1.1 Maximum demand metering 4.1.1.1.1 Block measuring period One possibility of forming the maximum is based on the measurement of the average power during a block measuring period tm. The time integral of the accrued energy is divided by the measuring period. If the current maximum demand value exceeds the highest measured maximum demand value since the beginning of the billing period, this value is saved as the new maximum demand in the relevant with the appropriate time stamp. The duration of the measuring period tm is derived from the real time clock (RTC). The duration of the measuring period can be configured to 1, 5, 10, 15, 30 or 60 minutes. The beginning of a measuring period is activated by an: Internal switching signal: − −
Tariff switching clock Ripple control receiver, or
External switching signal at one of the auxiliary terminals: − −
At the control input S0 At a control input (system voltage) configured for this purpose
Figure 32: Formation of the maximum demand with a block measuring period
56
4.1.1.1.2 Sliding measuring period An additional possibility of forming the maximum is measuring the average power over a sliding measuring period. The measuring period can be divided into several partial measuring periods depending on the measuring period length. By means of this, a sliding average value is created which is updated at the end of each partial measuring period. This average value is saved in a circular memory at the end of every partial measuring period and the sliding maximum is calculated on the basis of the entries saved in this circular memory. Formation of the sliding maximum begins with the first partial measuring period after a reset. As can be seen from the following example, a complete measuring period (in the example with 3 partial measuring periods) is required before the first valid value (1.85 kW) is available. A new, valid sliding measuring period is available at the end of each next partial measuring period. If the current power value exceeds the highest power value which has occurred since the beginning of the sliding measuring period, it is saved as the new, valid maximum in the appropriate with a measuring period time stamp. The measuring period duration can be configured to 1, 5, 10, 15, 30 or 60 minutes. With a measuring period of ≤ 30 min, the duration of the partial measuring period is 1 min. With a measuring period of 30 to 60 min, the duration of the partial measuring periods is 5 min. The beginning of a measuring period is activated by an: Internal switching signal: − −
Tariff switching clock Ripple control receiver, or
External switching signal at one of the auxiliary terminals: − −
At the control input S0 At a control input (system voltage) configured for this purpose
The following example shows the calculating of sliding measuring periods by means of 3 partial measuring periods.

Figure 33: Formation of the maximum demand with a sliding measuring period
The values from the sliding measuring period result from the sum of the last 3 entries from the circular memory. Measuring period 1: (0+0+0) = 0 kW Measuring period 2: (0.57+0+0) = 0.57 kW Measuring period 3: (0.72+0.57+0) = 1.29 kW Measuring period 4: (0.56+0.72+0.57) = 1.85 kW Measuring period 5: (0.83+0.56+0.72) = 2.11 kW Measuring period 6: (0.65+0.83+0.56) = 2.04 kW Measuring period 7: (1.03+0.65+0.83) = 2.51 kW Measuring period 8: (1.18+1.03+0.65) = 2.86 kW Measuring period 9: (0.85+1.18+1.03) = 3.06 kW

4.1.1.2 De-coupling time te In order to control other devices (e.g. a maximum demand monitor), a so-called decoupling signal te can be generated at an output (aux. terminal) or the optical fibre interface. Part 4 of VDE 0418 regulation stipulates that the de-coupling time may not exceed the higher of the following: 1% of the measuring period or 15 seconds. This de-coupling time is part of the measuring period and is generated at the beginning. In Europe, the measuring period most commonly used is 15 minutes (= 900 s), therefore the de-coupling time is 9 seconds. Electronic maximum demand meters need practically no de-coupling time. The de-coupling time te is distinguished by the speed of the software running time and rapid switching in the semiconductor elements which lies at a maximum in the millisecond range. Although the de-coupling signal is output externally with 1% of the measuring period, with electronic maximum demand meters there is a continual measuring process during this period.
4.1.1.3 Reset (cumulation) A reset has the following effect: − − − − − − − − −
Termination of the running measuring period Saving of the current maximum demand in the corresponding pre-value memory Cumulation of the current maximum demand in the cumulation Reset of the maximum demand to zero Reset of the current average power value to zero Saving of the energy values accrued until the time of the reset in the relevant prevalue memory Activation of a reset inhibition Incrementing of the reset 0.1.0 Registration of the reset time in the appropriate pre-value memory
A reset can be activated by one of the following: -
Reset button
-
The internal tariff switching clock
-
The internal ripple control receiver An external control input
-
By a command via the optical data interface D0 By a command via the electrical data interface
After a reset, depending on the selected reset channel, a temporal lock is activated. During this lock-out time no further resets can be carried out. The lock-out time is at least the duration of a measuring period and at the most 40 days. With each reset the block time is activated once again. Three block times with different durations can be set.

4.1.1.4 Load profile 4.1.1.4.1 General Fundamentally two independent load profiles can be created from the LZQJ-XC. −
P.01 Standard load profile According to VDEW-Specifications 2.1
−
P.02 load profile Recording of the measured values for the network analysis according to EN 50160 standards
4.1.1.4.2 Standard load profile P.01 a.
b.
Measuring types There are principally three ways of measuring the individual load profile channels. −
Average value, OBIS value group D = 5 The calculation of the average value takes place analog to the maximum formation (see 4.1.1.1 Maximum) which means that the average value of every registration period arises from the time integral during the run period divided by the registration period duration.
−
Energy, OBIS value group D = 8 At the end of each registration period the current values from the energy s are saved.
−
Energy feed, OBIS value groups D = 29 At the end of each registration period the differences between the current values from the energy s and from the starting point of the registration period are saved..
Example of a load profile with a regsitration period length of 15 min /EMH4\@01LZQJC0012B P.01(0060323125020)(00000000)(15)(3)(1.5)(kW)(1.8)(kWh)(1.29)(kWh) (1.000)(00100.000)(0.2500) (1.000)(00100.250)(0.2500) (1.000)(00100.500)(0.2500) (1.000)(00100.750)(0.2500) (1.000)(00101.000)(0.2500) The load profile consists of header lines [P.01()] and value lines. The headers consist of a time stamp, status information and channel information on the readout values. The time stamp relates to the value lines and each marks the end of this period. The output format corresponds to the definition in the VDEW-Specifications 2.1.
c.
Memory depths Assuming there are 2 headers per day, tm = 15 min, the format is x.xxx kW and there is an exclusive configuration of the standard load profile, the following maximum memory depths would be the result. With simultaneous configuration of the load profile P.02 the memory depths decrease. Number of channels

The number of channels can be configured between 1 and 6 (as an option up to 32) and a measured variable can be freely assigned to each channel. The load profile always runs clock synchronised. The restart of a registration period (with tm = 15 min) takes place every ¼ h (time from the meters real time clock), which means at hh:00, hh:15, hh:30 and hh:45 o’clock. In the event of a voltage failure the current time is saved in the data protection memory. After power return, two methods are differentiated between: a) Power return within the current registration period: No new registration period is formed, the current registration period continues. Power return outside the current registration period: A new registration period is formed. b) With each power return a new registration period is formed The load profile can be represented in the display. The load profile can be certified and used for billing purposes. The load profile depth for output via data interfaces can be configured and integrated in up to four readout tables so that the volume of data can be selected to fit various requirements. Furthermore there is the possibility to read out targeted periods of the load profile.

6 Special features 6.1 Manipulation recognition For ing manipulation attempts, the LZQJ-XC can be equipped with a manipulation recognition system which s manipulation when the housing cover and terminal cover are removed or when there is magnetic interference.
6.1.1 Principle functions On the main board there are 2 micro buttons. The meter cover and terminal cover both have a pin on the inner side. Each time the meter cover or the terminal cover is removed, a manipulation attempt is ed by the respective micro button. By equipping the LZQJ-XC with a buffer battery the removal of the housing cover or terminal cover is also ed when the meter is switched off.
6.1.2 Output possibilities There are 4 possibilities to show a manipulation attempt. 1) 2) 3) 4)
Cursor in the display Registration entry Activation of an alarm Log book entry
Figure 36: Output of manipulations
6.1.2.1 Cursor in the display When a manipulation attempt is ed a cursor appears at the top right in the display next to “MAN”.
How to reset a manipulation can be freely configured.
76
6.1.2.2 entry Manipulation attempts are shown by the first digit of the installation check C.86. The digit “1” indicates manipulation of the meter cover:
The digit “2” indicates a manipulation of the terminal cover:
The digit “4” indicates manipulation from magnetic fields:
There are many different possibilities for resetting the registration entry.
6.1.2.3 Activation of an alarm A manipulation message can be sent to the control centre via an alarm and a meter modem. A manipulation message can also be sent as an Short Message (SMS).
6.1.2.4 Log book entry 6.1.2.4.1 log book P.200 Every manipulation attempt is ed in the defined log book P.200. This data can also be read out via the service table TS. The beginning and end of the last manipulation is ed and saved with information on the time and date and also the number of manipulation attempts (provided meter is in the operation condition). Examples: P.200(0060120085945)(00002000)()(0)

6.2 Overload monitoring The LZQJ-XC can be equipped with an overload monitoring feature which detects when the configured overload threshold is exceeded during a measuring period. Values from 0 to 99.999.999 kW are permitted. Setting the overload threshold Open “Direct” > “LZQJ-settings (VDEW2.1)...” > “Overload threshold”
First of all read out the overload threshold set in the meter. Afterwards you can change the values and write them back into the meter. Further information can be found in the manual EMH-COMBI-MASTER 2000. The sum of all overranges are saved in the 1.36.0.01.
The maximum demand M0 for current consumption P+ 1.4.0 or the 1.25 for the momentary value for P+ is used as a basis for recognising overconsumption. When the overconsumption threshold is exceeded a cursor (PWR) is shown in the display. An alarm can also be switched. Information on the overconsumption threshold can be found in the call-up list and in table 1.
Figure 37: Diagram - Overconsumption

6.3 Installation check C.86.0 In the installation check C.86.0 installation errors are saved. The monitored measured variables result from the instantaneous values. The installation check is usually shown in the scrolling list or can be called up via the call-up list. The installation check has 32 error flags which are represented by an 8 digit hexidecimal number. With a correct installation of the meter, the contains the value “00000000”.

6.4.2 Voltage quality C.86.1 In the voltage quality C.86.1 the over- and underranges of the voltage parameters are saved. The can also be used as a status channel in the load profile P.02. The limiting values are defined in DIN EN 50160, they can also be configured to suit customer requirements. From the monitored values the average values are formed via the registration period of the load profile P.02. At the end of a registration period the values are compared with the guidelines and if necessary saved in the appropriate s. The voltage quality has 32 error flags which are represented by means of an 8 digit hexadecimal number. The sum of all over- and underranges are saved in the s C.88.00...31.

6.7 Load switching As an option, the LZQJ-XC can be executed with a switching off relay for switching the load/power. By means of this, the power supply can be switched on or off at the final . There are different cases of application which are described in the following.
6.7.1 Example cases 6.7.1.1 Example case 1 The customer (eg. holiday home owner) swiches the power supply off at the meter on site using the call-up button. Switching back on also takes place via the call-up button. 6.7.1.2 Example case 2 In spite of many warnings the customer has not paid their electricity bill. The energy supplier switches off the power supply to the customer via remote control. After payment of the bill the power supply is switched back on. The power supplier also reactivates the meter via remote control. Subsequently the customer can activate the power supply by operating the call up button. 6.7.1.3 Example case 3 The customer has agreed a limited power supply with the energy supplier (e.g. Pmax = 10 kW). If this power threshold is continually exceeded, the meter switches off the load. Depending on the configuration there are different possibilities to switch it back on: − − −
via a direct command from the energy supplier via a release command from the energy supplier for the customer to switch it on manually via the call-up button by the customer
6.7.1.4 Example case 4 The customer has agreed a limited power supply with the energy supplier (e.g. Pmax = 10 kW). If this power threshold is continually exceeded, the meter switches off the load. The customer has no access to the meter which means that he cannot switch it on again directly. In this case the meter swiches on the load again automatically after the disconnection time has lapsed.

6.7.2 Load switching 6.7.2.1 Load switching via the call-up button Operation display
Via the menu option “LOAd OnIOFF” in the menu “Call-up button” the switching of the load can be carried out directly on the meter. By operating the call-up button 2 s < t < 5 s the submenu option “LOAd OFF” or “LOAd On” appears independent of the relay position. “LOAd OFF”: By operating the call-up button > 2 s the load is switched off. The display returns to the operation display. With a successful switching off, the display “OFF” appears. If the switching process failed, “LOAd Error” appears. The meter can still be operated.

6.7.2.2 Load switching via commands Switching on and off the load using a command takes place via the meters interfaces (D0, CL0, RS232, RS485, radio). 6.7.2.3 Manual load switching Release for the manual switching on of the load takes place via the meters interfaces (D0, CL0, RS232, RS485, radio). Release can be identified via the display “PrESS:On” .
The meter can no longer be operated in this condition. By operating the call-up button > 5 s the load is switched back on again. Afterwards the meter can be operated again as normal. 6.7.2.4 Load switching by means of excess load 6.7.2.4.1 Switching off by means of excess load When a fixed power threshold is exceeded the load us switched off. This threshold can be set and saved in the 1.35.0.01(). In the regiser 1.35.0.02() a “forewarning threshold” can be saved. When one of the thresholds is reached, this is signalised in the display by the sideward cursor “PWR”. If no thresholds are configured, no power monitoring takes place. Threshold monitoring takes place by means of the power instantaneous value 1.25. Switching off takes place after a fixed lag time as long as the power is exceeded for the whole of the lag time. If the switching off is successful, “OFF” appears in the display. The meter can still be operated. The power thresholds and the lag time can be set via the meters interfaces (D0, CL0, RS232, RS485, radio). 6.7.2.4.2 Automatic switching on If the load is switched off due to power monitoring, this is switched back on again after a fixed diconnection time. If no disconnection time is configured, the load is not switched back on automatically. The disconection time can be set via the meters interfaces (D0, CL0, RS232, RS485, radio).
6.7.3 Monitoring the switch off condition If the load is switched off, the meter checks its idle condition. If this is not given after the switching off, the meter repeats its power down process cyclically. When the idle condition is fulfilled, “OFF” appears in the display. If the switching off fails, “LOAd Error” appears in the display. Additionally an entry appears in the status for load switching C.86.8(). At the same time, a time meter is activated which records the hours in which the load was connected. The time meter can only be reset by deleting the measured data. Even if the switching off fails, the meter can still be operated and commands can be received. Note: A continuous base load above the meters response threshold is a requirement for the monitoring function.

6.8 Recording external measuring variables The LZQJ-XC is capable of ing other impulses from reference-, thermal-, wateror gas meters via 4 impulse inputs. From these inputs, energy values, maximum demand and load profiles can be formed. These measuring variables can then be read out via the LZQJ-XC meter.
Figure 40: Application plan - recording load profiles form other media
Figure 41: Diagram - Recording of load profiles from several meters
Pulse counting In order to avoid incorrect registration of pulses, the minimum pulse length and no-pulse period can be set in 5ms steps. Furthermore the activating edge (rising or falling) can be selected. A ed pulse is evaluated by means of a settable pulse constant and a unit.The quantums which are formed in this way can either be summed among eachother or added to or subtracted from the measuring variables formed internally in the meter. When an input pulse constant is changed, an entry is made in the certification relevant log book P.99 (see 5.2.7 Certification relevant log book (menu option “P.99”)). All measuring variables resulting from this are available as an input channel for the energy- and maximum demand s and for the load profile formation.
88
Example: Via the pulse input with the channel number 2, active power proportional pulses are counted. These are then added to the variables formed in the meter and ed in separate meter s with the channel number 13 (see also 8.1 OBIS (ObjectIdentification-System)). OBIS code

Shortened no-load test LED is continuously lit-up = no load, energy direction arrows are not displayed Shortened start-up test The LED starts to flash. The energy direction arrows display the measured energy direction.
7.2 Test load Test loads for testing meters which have several nominal voltages (long-range) or 1 a nominal voltage range This test is to be carried out at the upper and lower voltage rate which is specified on the nameplate, provided no other conditions are specified in the approval. Test loads for testing meters which have two nominal currents
1
With the test of meters with two nominal currents (e.g. 5||1 A) the lowest test point (5% or 10%) is measured with the smaller nominal current. All other test points are measured using the higher nominal current. Testing of meters with two energy directions
1
As long as no other regulations are specified in the approval documents meters which measure energy in both directions are measured in a way as if two separate meters for import and export are being dealt with.

8.4 Software 8.4.1 EMH-COM EMH-COM is a modular developed software which enables communication between a readout device (e.g. PC or laptop) and EMH meters. The software is designed especially for starting up the meter, reading out data from the meter and also for changing the basic settings. Due to the modular set-up, the software can be tailored directly to the customer’s requests.
The most important functions of the programs are: − − − − − −
Reading out of meter data Graphical load profile display Setting the clock Modem function (optional) Tariff settings for different meter (optional) Send write command (optional)
8.4.2 EMH-COMBI-MASTER 2000 The EMH-COMBI-MASTER 2000 contains all functions of theEMH-COM program and allows in addition the configuration of meters from the series LZQJ-XC.
The most important functions of the programs are: − − − −
All functions contained in the EMH-COM software Configuration of meters Setting of transformer ratios and digitness with transformer meters Further optional functions such as readout of the network quality and harmonics 97
8.4.3 EMH-Mobile EMH-Mobile is a mobile and manageable tool for starting up and reading out electricity meters on location. EMH-Mobile consists of a PDA (Personal Digital Assistant) and an optical communication adapter (Bluetooth-OKK). With both devices, a wireless communication is possible via a Bluetooth-interface
Figure 42: EMH-Mobile
The software EMH-Mobile is installed on the PDA for communication with meters. Special features of the software include “Installation check” (possible with all EMH meters with a service table) and also the readout of electronic household meters eHZ. Via the “Installation check” the meter connection can be easily checked. Connection errors can therefore be detected on location.

8.5.2 Possibilities of meter communication In the following, the communication between a readout device and a meter via the optical- or electrical interface are described.
8.5.2.1 Communication via optical interface The optical communication adapter OKK enables communication between a readout device (e.g. PC or laptop) and EMH meters. On the meter the connection is to the optical data interface D0 and on the PC, depending on the version, the connection is to a COMport or to a USB interface. Connection of the OKK: Connect the optical communication adapter OKK to a free COM-Port or a free USB interface on your PC. If you have an OKK with USB connection then a special USB driver must be installed. The driver can be found on the CD-ROM which is included in the delivery with the OKK. Tips for the installation of the driver can also be found on the CD-ROM. Note: Before communication can take place with the meter the interface must be configured under “Setting” > “Program settings...” >. (see 8.5.3.1 General settings).
8.5.2.2 Communication via electrical interface Communication with the meter via the connection PC-modem-meter modem (remote meter read out) requires the definition of some parameters (see 8.5.3.2 Modem).

2 Tips on mounting and installation 2.1 General safety tips The meters are to be used exclusively for measuring electrical energy and must only be operated within the specified technical data (see nameplate). When installing or changing the meter, the conductor for which the meter is connected must be de-energised. For this purpose only the provided terminals must be used. to parts under voltage is extremely dangerous; therefore the relevant backup fuses are to be removed and stored so that other people cannot insert these unnoticed. Before opening the meter, the secondary circuit to the current transformer must definitely be short circuited. The high voltage on the current transformer is extremely dangerous and destroys the current transformer. With an incorrect installation of the meter, the S0 inputs can lead to mains voltage. Caution: danger! The local standards, guidelines, regulations and instructions are to be obeyed. Only authorised, trained personnel are permitted to install the electricity meters.
2.2 Maintenance- and guarantee tips The meter is maintenance-free. With damages (e.g. caused by transportation or storage) no repairs may be carried out. Once the meter has been opened, all warranty claims cease. This also applies if a defect can be traced back to external influences (e.g. lightning, fire, extreme temperature- and weather conditions, incorrect or careless use or treatment).
12
2.3 Mounting Meters from the series LZQJ-XC are suitable for wall mounting according to DIN 43857-2.
Figure 1: Dimensions
13
2.4 Installation When connecting the meter it is very important to take notice of the circuit diagram which you can find on the inside of the terminal cover and also in the delivery documents. In chapter 2.6 Circuit diagrams on page 16 you can find examples of these.
2.4.1 Transformer operated meter Meters for transformer operation are to be protected with a back-up fuse of < 10 A in the voltage path.
Figure 2: Back-up fuse with transformer operated meters
2.4.2 Direct connected meter Meters for direct connection are to be protected with a back-up fuse of 100 A.
Figure 3: Back-up fuse with direct connected meters
14
Installation check After installation of the meter, it is possible to check if it has been connected correctly by means of the function “Installation check“ in the EMH-COM/COMBIMASTER 2000. This function is not a standard part of the EMH-COM/COMBIMASTER 2000 program, however, can be ordered as an additional module. Open “Readout“ > “Installation check“
The graphic installation display shows the current network behaviour. In the table the current values of phase L1, L2, L3 and also the sum of all phases are shown.
Further information can be found in the manual EMH-COMBI-MASTER 2000.

2. The battery status display shows the charging status of the buffer battery of the real time clock. The following displays are possible: = full voltage, real time clock is buffered when there is no voltage = discharged, no buffering of the real time clock is possible 3. The communication display is continually lit-up when there is communication with the meter via data interfaces (optical or electrical) or the display flashes when the parameterisation status is active. 4. The phase display signalises connection of the individual phase voltages. With an incorrect rotating field all three symbols flash. 5. The unit is displayed corresponding to the measured energy type or the displayed measured value. 6. In the additional cursor field, operation conditions of the meter are represented. The black arrows show if a manipulation or an installation error has been ed or if the performance threshold has been exceeded. MAN
The cursor is active if a manipulation has been ed on the terminalor meter cover or electromagnetic interference.
INST
The cursor is active if an entry has been ed in the installation check .
PWR
The cursor is active if a power threshold set in the meter is exceeded.
7. In the standard cursor field, operation conditions of the meter are represented. The black arrows show which tariff and maximum demand is active and via which hardware (clock or ripple control receiver) the meter should be controlled. T1-T4
Tariff information for energy. All tariff s which can be activated are displayed on the nameplate.
M1-M4
Tariff information for maximum demand. All tariff s which can be activated are displayed on the nameplate.
RCR
The cursor flashes when the internal RCR is activated and ready to receive. The relevant cursor is continually active when the internal ripple control receiver receives a telegram.
RL
The cursor flashes for the duration of the activation of a reset inhibition.
CLOCK
The cursor is active if the internal clock controls the tariff device.
SET
The cursor is active when the meter is in the set mode.
8. In the value area the measured values are represented. 9. In the OBIS code area the measured values are defined by means of the OBIS code. The display is capable of displaying the long OBIS code (see page 91).
31
3.3.2 Test - LEDs The Test-LEDs are used for the output of energy proportional active- and reactive energy impulses, for certification of the meter and for the display of start-up and no load operation. The impulse constants depend on the meter type. If the meter measures no current or current below the start-up threshold, the meter is in the no-load operation mode. In this case, the LED is continually lit-up. With Combimeters the LED is continually lit-up if the energy flow direction is negative. If the meter measures current above its start-up threshold, energy proportional impulses are displayed.
3.3.3 Call-up and reset button The call-up button serves to call up the display lists in the display. Via the reset button, which is situated behind the sealable module cover, a manual reset can be carried out.
3.3.4 Optical call-up sensor The optical call-up sensor serves to call up the display lists in the display. Operation of the display takes place by means of a pocket lamp.
3.3.5 Parameterisation button The parameterisation button is used to activate the parameterisation status in the meter. The button is located under the meter cover. To operate this button the meter must be opened which means the seals must be broken. Breaking the seals means that the certification expires and therefore this may only be carried out by authorised personnel. When the meter is in the parameterisation status the communication symbol flashes in the display.
3.3.6 Optical data interface D0 Communication between the meter and PC takes place via the optical data interface. An optical communication adapter OKK is required for this. In order to fix the OKK to the meter there is a magnetic ring which is found on the meter cover. Further information on the optical data interface can be found on page 40.
3.3. Meter cover The meter cover is made of crystal clear polycarbonate. The housing cover is mounted at the bottom in the baseplate and screwed at the top with both of the sealing screws. With the relevant configuration, when removing the housing cover, a manipulation is ed. More detailed information can be found on this in chapter “6.1 Manipulation” on page 76.
32
3.3.8 Sealable terminal cover The terminal cover is made of grey polycarbonate and is fixed to the terminal block with sealing screws. The circuit diagram is fixed on to the inside of the terminal cover. With the relevant configuration, when removing the terminal cover, a manipulation is ed. More detailed information on this can be found in chapter “6.1 Manipulation“ on page 76.
3.3.9 Battery compartment The battery compartment is found under the sealable module cover. A lithium battery (CR-P2, 6 V) can be assembled here which, if necessary, can be exchanged. The battery is used for reading out the meter via the optical interface and for reading the display during power failure. It also buffers the real time clock. In the delivery status the battery function is not active. To activate it, open the hinged cover and pull out the readout battery. Then remove it from the holder and flip it over so that the battery s to the compartment. Afterwards push the battery incl. folder in the battery compartment with the s of the compartment facing left. Finally close the hinged cover.
3.3.10 Communication module compartment The communication module compartment is found under the sealable module cover. Here a modem- or interface module can be inserted. Mounting and removal can take place when the meter is under voltage. Further information on the modules can be found on page 17 and also in the LZQJ accessories catalogue.
3.3.11 Nameplate The nameplate contains data for identification of the meter, the approval mark, technical specifications and explanations. The cursor lettering below the display and the description of the OBIS code on the nameplate are standard and not adapted to the meter version. The nameplate can contain more information than is configured on the existing version. The parameterised functions are to be taken from the list of desied features.
3.3.12 Transformer nameplate Transformer operated meters (in general secondary meters) are equipped with a transformer nameplate which is found under the sealable module cover. On the transformer nameplate the following information is displayed:

3.4 Modules Fundamentally the meter consists of: − − − − −
Switched-mode power supply Measuring device Tariff device Interfaces In- and outputs
In the following the most important modules are described.
3.4.1 Voltage supply 3.4.1.1 Direct supply The LZQJ-XC is supplied via a primary switched, long-range power supply (3x58/100 V ... 3x240/415 V) with a high degree of efficiency. The power supply is “earth-fault proof“ and guarantees operation without the neutral conductor (N). In case a component fails during operation the power supply is overload- and short-circuit-proof. With single-phase connected meters from the LZQJ series a faultless operation up to Unom + 15% / - 20% is guaranteed. Permitted voltage versions: Measuring voltage

3.4.1.2 Auxiliary voltage Only valid for LZQJ-XC-P2 ... and LZQJ-P5 ... (precision meters with accuracy class 0.2 and 0.5)! The LZQJ-XC as a precision meter has the possibility of external auxiliary voltage supply. In general there are two types of supply which are differentiated between: a) Auxiliary supply The energy for the electronic measuring device is only taken from the auxiliary supply. The auxiliary supply and measuring circuit voltage are galvanically separated. b) Combined supply With certain voltage conditions the power for the electronic device is no longer taken from the auxiliary supply, instead, it is taken from the measuring circuit voltage. If the auxiliary supply completely fails, the power for the electronic measuring device is taken exclusively from the measuring circuit voltage (feature of the combined supply). This means, the meter is completely capable of functioning even if the auxiliary supply fails (advantage when compared to option a)). The presence of auxiliary voltage supply relieves the load in the voltage paths in the measuring system, resulting in a substantial decrease in apparent power consumption (see Table 10).
34
Measuring voltage
Apparent power consumption per measuring-circuit voltage path

3.4.2 Measuring device 3.4.2.1 Measuring principle The electrical energy is measured by processing the sampling values which the Analog Digital Transformers (ADC) send to the processor. By means of this, all of the measured values can be measured or calculated in all quadrants. The calculation ensures that the values are stable and resistant to ageing.
Figure 16: Definition of quadrants
3.4.2.1.1 Voltage measurement The terminal voltages create network proportional internal voltage levels at internal voltage dividers. These are fed into the 3 input channels of the ADC.
3.4.2.1.2 Current measurement For measuring current, error compensated current transformers are used. The output variables of the respective amplifier are fed into the 3 input channels of the ADC.
35
3.4.2.1.3 Data protection During operation the current measurements are stored in the working memory (RAM). Every 24 hours this data is transferred to a non-volatile memory. It is only in cases of longer interruptions that the measuring period is interrupted and the device completely shuts down. Data remains stored in the non-volatile memory for at least ten years. No buffer battery is needed to preserve the data. The data retention is assured exclusively by the qualities of the storage medium (Flash).
3.4.3 Tariff switching clock The tariff switching clock is integrated into the meter. It is based on a quartz-controlled, battery or capacitor-buffered real time clock (RTC) which provides time information (date, day of week, time) in second intervals. Switching times can be configured exclusively for the customer by means of: −
16 season tables,
− −
16 day types or 384 holiday definitions for any weekdays
These switching times are compared continually with the real time clock. If they coincide with the configured switching times or switching periods, the switching function is activated. Switching functions are the activation of the maximum demand s and energy s. As a result of this, 32 energy s and maximum demand s each with a maximum of 8 tariffs can be configured via the tariff switching clock. At the beginning of the summer period an hour is added on to the time of the tariff switching clock (CET). The beginning and end of the summer period is determined with the help of a summer time . This is settable in order to be able to react to possible changes of the current valid summer time regulations. The accuracy of the real time clock is within ± 5ppm. The buffering of the real time clock (RTC) can take place by a SuperCap-capacitor with a running reserve of approx. 6 days (150 hours). With a completely discharged SuperCap the charging time is approx. 18 min after applying the voltage phases (90% voltage). Instead of a SuperCap-capacitor, the buffering can take place by using a battery (dry Li-battery) with a running reserve of > 20 years. The latter is recommended for meters with load profile memories so that the load profile is correctly dealt with chronologically when there are longer power interruptions or if the meter has been turned off for longer periods. As a rule, the real time clock is quartz controlled however, can also be synchronised via the following variations: − Synchronisation of the real time clock via the line frequency The clock is synchronised cyclically by a mains frequency controlled timer −
Synchronisation of the real time clock via an impulse at the input Synchronisation takes place at o the next full 1 minute or o next measuring period limit or o a fixed time of the day
−
Synchronisation of the real time clock via a DCF77-receiver connected to the S0-input DCF77 is a time signal which is emitted via longwave. The circulation is carried out by the PTB and serves as the legal time. In the DCF77 signal, time information of the next complete minute is coded to which the meter then synchronizes itself.

The telegrams differ by their command evaluation procedure and by their digital structure of the pulse sequence. The ripple control receiver can switch 6 ripple control relays which are available for control functions of the meter. Also tariff- and maximum demand controls, resets and caution signals can be ed on directly via terminals or optical fibre interfaces. Reading out and setting of the RCR position of the ripple control receiver Open “Direct“ > “RCR position...“
After activation of the menu option, the relay position of the ripple control receiver is read out first of all. Next a window opens in which the relevant relay position is marked with an “X”. The relay position can be changed by means of a double click on the appropriate field. To send the changed settings to the meter click on “Write“.

3.4.5 Data interfaces Data exchange between meters and readout devices (eg. PC, modem, PDA, etc.) takes place via the optical interface (D0) or, at auxiliary terminals, via the electrical interface (RS232, RS485, CL0). Communication is in accordance with DIN EN 62056-21 or DLMS. 3.4.5.1 Optical data interface D0 Communication between the meter and the PC takes place via the optical data interface. For this an optical communication adapter (OKK) is necessary which can be obtained from EMH. The OKK is available for connection to a readout device with a RS232-, USBor Bluetooth interface. It has a magnet to fix it to the iron ring situated on the front of the housing cover. Transmission rates from 300 to 9600 Baud, fixed or mode C/E can be set.

3.4.5.2 Electrical interface Depending on the model, the LZQJ has the following electrical interfaces: − − −
CL0 RS485 RS232
Simultaneous operation of the first electrical interface and optical interface is not possible. In addition to the above listed interfaces a modem- or interface module can be mounted in the communication module compartment. By means of this it is possible to grant third parties restricted access to the meter data. The first interface can be used in parallel by the utility company for meter communication with access to all data. By means of a multilevel concept, the access rights can be easily assigned.

3.4.5.2.3 Electrical interface CL0 (CS) The galvanic de-coupled CL0 interface is designed according to DIN 66348, part 1. It is a ive two-wire interface which means that it does not have its own power source. The data is transmitted by electric current / no electric current (Mark/Space) at a nominal current of 20 mA which is the reason why the CL0 interface is also referred to as the 20 mA current interface. The CL0 can be found at the auxiliary terminals 23 (+) and 24 (-) in accordance with the VDEW-Specifications 2.1.

3.4.5.3 Optical fibre interface LLS At the meter terminal L there is a coupling point to which an optical fibre can be connected by simply plugging- and screwing in. The other end of the optical fibre is plugged into the optical fibre separation box. The optical fibre interface can be found at the auxiliary termnal L.
Figure 24: Connection diagram - LLS
The optical fibre separation box is in DIN-Rail housing according to EN 50 022 and it has its own optical fibre output so that a total of four relay boxes can be cascaded.
Figure 25: Connection plan - LLS
For each relay box up to 6 control outputs can be realised, altogether a total of 24 control outputs. Each output of the optical fibre separation box can be designed as a relay(optional with suppressor circuit) or Opto-MOSFET output or as a make- or break . The optical fibre separation box is supplied by a long range network power supply from 100V to 230V. A complex input suppressor circuit protects the meter from destruction as a result of bad power supply. With the described arrangement, an optimal isolation is obtained by means of galvanic separation of the optical fibre between the meter and relay boxes. Features Number of connected boxes

3.4.6.5 Important tips for mounting and installation Safety tips The communication modules are electronic appliances and may not be used for any other purposes. Mounting may only be carried out by electronic specialists according to the generally recognised codes of practice and according to the standard requirements for the installation of telecommunication systems and devices. Before assembly, please examine the communication module for any exterior, obvious transport damages and on location check the electrical operating conditions. Mounting can take place under voltage. The communication module should be stored, used and transported in a way so that the pins cannot be damaged. Assembly of the external aerial with GSM- and GPRS modules When assembling the exterior aerial (which is available as an optional accessory) the assembly fixing bracket must be earthed against lightning by a specialist! Inserting the SIM card in the GSM- and GPRS modules Only insert the SIM card when the appliance is switched off! Maintenance- and guarantee tips The communication module is maintenance-free. With damages (e.g. caused by transportation or storage) no repairs may be carried out. Once the meter has been opened, all warranty claims cease. This also applies if a defect can be traced back to external influences (e.g. lightning, fire, extreme temperature- and weather conditions, incorrect or careless use or treatment).

4 Firmware Diverse configurable variables have been programmed in the meter which define the meters functions. These include: − −
settable variables parameterable variables
Settable variables can be changed by operation buttons or one of the interfaces. Parameterable variables include variables which define the properties of the counter. Parameterable variables can be changed via the optical interface D0 or one of the electrical interface. To do this, the meter must be in the parameterisation status (by pressing the parameterisation button). To operate the parameterisation button, the meter cover must be opened which means that the seals must be broken. Breaking the seals means that the certification is no longer valid and may therefore only be carried out by authorised personnel. When the meter is in the parameterisation status only the communication symbol flashes. The parameterisation status is ended by means of the following: − −

4.1 Tariff device The tariff device calculates the consumed or supplied electrical power or energy on the basis of the digitalised measured values and allocates it to the power and energy s.
4.1.1 Energy- and maximum demand tariffs With the LZQJ meter, a maximum of 32 s each can be configured for electrical energy and maximum demand. Each has a memory with up to 15 pre-values which represent the measured values and the time stamp of the last 15 reset periods. The assignment of the measured variables is configured at EMH according to the customer’s requirements. 4.1.1.1 Maximum demand metering 4.1.1.1.1 Block measuring period One possibility of forming the maximum is based on the measurement of the average power during a block measuring period tm. The time integral of the accrued energy is divided by the measuring period. If the current maximum demand value exceeds the highest measured maximum demand value since the beginning of the billing period, this value is saved as the new maximum demand in the relevant with the appropriate time stamp. The duration of the measuring period tm is derived from the real time clock (RTC). The duration of the measuring period can be configured to 1, 5, 10, 15, 30 or 60 minutes. The beginning of a measuring period is activated by an: Internal switching signal: − −
Tariff switching clock Ripple control receiver, or
External switching signal at one of the auxiliary terminals: − −
At the control input S0 At a control input (system voltage) configured for this purpose
Figure 32: Formation of the maximum demand with a block measuring period
56
4.1.1.1.2 Sliding measuring period An additional possibility of forming the maximum is measuring the average power over a sliding measuring period. The measuring period can be divided into several partial measuring periods depending on the measuring period length. By means of this, a sliding average value is created which is updated at the end of each partial measuring period. This average value is saved in a circular memory at the end of every partial measuring period and the sliding maximum is calculated on the basis of the entries saved in this circular memory. Formation of the sliding maximum begins with the first partial measuring period after a reset. As can be seen from the following example, a complete measuring period (in the example with 3 partial measuring periods) is required before the first valid value (1.85 kW) is available. A new, valid sliding measuring period is available at the end of each next partial measuring period. If the current power value exceeds the highest power value which has occurred since the beginning of the sliding measuring period, it is saved as the new, valid maximum in the appropriate with a measuring period time stamp. The measuring period duration can be configured to 1, 5, 10, 15, 30 or 60 minutes. With a measuring period of ≤ 30 min, the duration of the partial measuring period is 1 min. With a measuring period of 30 to 60 min, the duration of the partial measuring periods is 5 min. The beginning of a measuring period is activated by an: Internal switching signal: − −
Tariff switching clock Ripple control receiver, or
External switching signal at one of the auxiliary terminals: − −
At the control input S0 At a control input (system voltage) configured for this purpose
The following example shows the calculating of sliding measuring periods by means of 3 partial measuring periods.
57
Figure 33: Formation of the maximum demand with a sliding measuring period
The values from the sliding measuring period result from the sum of the last 3 entries from the circular memory. Measuring period 1: (0+0+0) = 0 kW Measuring period 2: (0.57+0+0) = 0.57 kW Measuring period 3: (0.72+0.57+0) = 1.29 kW Measuring period 4: (0.56+0.72+0.57) = 1.85 kW Measuring period 5: (0.83+0.56+0.72) = 2.11 kW Measuring period 6: (0.65+0.83+0.56) = 2.04 kW Measuring period 7: (1.03+0.65+0.83) = 2.51 kW Measuring period 8: (1.18+1.03+0.65) = 2.86 kW Measuring period 9: (0.85+1.18+1.03) = 3.06 kW

4.1.1.2 De-coupling time te In order to control other devices (e.g. a maximum demand monitor), a so-called decoupling signal te can be generated at an output (aux. terminal) or the optical fibre interface. Part 4 of VDE 0418 regulation stipulates that the de-coupling time may not exceed the higher of the following: 1% of the measuring period or 15 seconds. This de-coupling time is part of the measuring period and is generated at the beginning. In Europe, the measuring period most commonly used is 15 minutes (= 900 s), therefore the de-coupling time is 9 seconds. Electronic maximum demand meters need practically no de-coupling time. The de-coupling time te is distinguished by the speed of the software running time and rapid switching in the semiconductor elements which lies at a maximum in the millisecond range. Although the de-coupling signal is output externally with 1% of the measuring period, with electronic maximum demand meters there is a continual measuring process during this period.
4.1.1.3 Reset (cumulation) A reset has the following effect: − − − − − − − − −
Termination of the running measuring period Saving of the current maximum demand in the corresponding pre-value memory Cumulation of the current maximum demand in the cumulation Reset of the maximum demand to zero Reset of the current average power value to zero Saving of the energy values accrued until the time of the reset in the relevant prevalue memory Activation of a reset inhibition Incrementing of the reset 0.1.0 Registration of the reset time in the appropriate pre-value memory
A reset can be activated by one of the following: -
Reset button
-
The internal tariff switching clock
-
The internal ripple control receiver An external control input
-
By a command via the optical data interface D0 By a command via the electrical data interface
After a reset, depending on the selected reset channel, a temporal lock is activated. During this lock-out time no further resets can be carried out. The lock-out time is at least the duration of a measuring period and at the most 40 days. With each reset the block time is activated once again. Three block times with different durations can be set.

Example of a load profile with a regsitration period length of 15 min /EMH4\@01LZQJC0012B P.01(0060323125020)(00000000)(15)(3)(1.5)(kW)(1.8)(kWh)(1.29)(kWh) (1.000)(00100.000)(0.2500) (1.000)(00100.250)(0.2500) (1.000)(00100.500)(0.2500) (1.000)(00100.750)(0.2500) (1.000)(00101.000)(0.2500) The load profile consists of header lines [P.01()] and value lines. The headers consist of a time stamp, status information and channel information on the readout values. The time stamp relates to the value lines and each marks the end of this period. The output format corresponds to the definition in the VDEW-Specifications 2.1.

Memory depths Assuming there are 2 headers per day, tm = 15 min, the format is x.xxx kW and there is an exclusive configuration of the standard load profile, the following maximum memory depths would be the result. With simultaneous configuration of the load profile P.02 the memory depths decrease. Number of channels

The number of channels can be configured between 1 and 6 (as an option up to 32) and a measured variable can be freely assigned to each channel. The load profile always runs clock synchronised. The restart of a registration period (with tm = 15 min) takes place every ¼ h (time from the meters real time clock), which means at hh:00, hh:15, hh:30 and hh:45 o’clock. In the event of a voltage failure the current time is saved in the data protection memory. After power return, two methods are differentiated between: a) Power return within the current registration period: No new registration period is formed, the current registration period continues. Power return outside the current registration period: A new registration period is formed. b) With each power return a new registration period is formed The load profile can be represented in the display. The load profile can be certified and used for billing purposes. The load profile depth for output via data interfaces can be configured and integrated in up to four readout tables so that the volume of data can be selected to fit various requirements. Furthermore there is the possibility to read out targeted periods of the load profile.

6 Special features 6.1 Manipulation recognition For ing manipulation attempts, the LZQJ-XC can be equipped with a manipulation recognition system which s manipulation when the housing cover and terminal cover are removed or when there is magnetic interference.
6.1.1 Principle functions On the main board there are 2 micro buttons. The meter cover and terminal cover both have a pin on the inner side. Each time the meter cover or the terminal cover is removed, a manipulation attempt is ed by the respective micro button. By equipping the LZQJ-XC with a buffer battery the removal of the housing cover or terminal cover is also ed when the meter is switched off.
6.1.2 Output possibilities There are 4 possibilities to show a manipulation attempt. 1) 2) 3) 4)
Cursor in the display Registration entry Activation of an alarm Log book entry
Figure 36: Output of manipulations
6.1.2.1 Cursor in the display When a manipulation attempt is ed a cursor appears at the top right in the display next to “MAN”.
How to reset a manipulation can be freely configured.
76
6.1.2.2 entry Manipulation attempts are shown by the first digit of the installation check C.86. The digit “1” indicates manipulation of the meter cover:
The digit “2” indicates a manipulation of the terminal cover:
The digit “4” indicates manipulation from magnetic fields:
There are many different possibilities for resetting the registration entry.
6.1.2.3 Activation of an alarm A manipulation message can be sent to the control centre via an alarm and a meter modem. A manipulation message can also be sent as an Short Message (SMS).
6.1.2.4 Log book entry 6.1.2.4.1 log book P.200 Every manipulation attempt is ed in the defined log book P.200. This data can also be read out via the service table TS. The beginning and end of the last manipulation is ed and saved with information on the time and date and also the number of manipulation attempts (provided meter is in the operation condition).

6.2 Overload monitoring The LZQJ-XC can be equipped with an overload monitoring feature which detects when the configured overload threshold is exceeded during a measuring period. Values from 0 to 99.999.999 kW are permitted. Setting the overload threshold Open “Direct” > “LZQJ-settings (VDEW2.1)...” > “Overload threshold”
First of all read out the overload threshold set in the meter. Afterwards you can change the values and write them back into the meter. Further information can be found in the manual EMH-COMBI-MASTER 2000. The sum of all overranges are saved in the 1.36.0.01.
The maximum demand M0 for current consumption P+ 1.4.0 or the 1.25 for the momentary value for P+ is used as a basis for recognising overconsumption. When the overconsumption threshold is exceeded a cursor (PWR) is shown in the display. An alarm can also be switched. Information on the overconsumption threshold can be found in the call-up list and in table 1.

6.3 Installation check C.86.0 In the installation check C.86.0 installation errors are saved. The monitored measured variables result from the instantaneous values. The installation check is usually shown in the scrolling list or can be called up via the call-up list. The installation check has 32 error flags which are represented by an 8 digit hexidecimal number. With a correct installation of the meter, the contains the value “00000000”.

6.7 Load switching As an option, the LZQJ-XC can be executed with a switching off relay for switching the load/power. By means of this, the power supply can be switched on or off at the final . There are different cases of application which are described in the following.
6.7.1 Example cases 6.7.1.1 Example case 1 The customer (eg. holiday home owner) swiches the power supply off at the meter on site using the call-up button. Switching back on also takes place via the call-up button. 6.7.1.2 Example case 2 In spite of many warnings the customer has not paid their electricity bill. The energy supplier switches off the power supply to the customer via remote control. After payment of the bill the power supply is switched back on. The power supplier also reactivates the meter via remote control. Subsequently the customer can activate the power supply by operating the call up button. 6.7.1.3 Example case 3 The customer has agreed a limited power supply with the energy supplier (e.g. Pmax = 10 kW). If this power threshold is continually exceeded, the meter switches off the load. Depending on the configuration there are different possibilities to switch it back on: − − −
via a direct command from the energy supplier via a release command from the energy supplier for the customer to switch it on manually via the call-up button by the customer
6.7.1.4 Example case 4 The customer has agreed a limited power supply with the energy supplier (e.g. Pmax = 10 kW). If this power threshold is continually exceeded, the meter switches off the load. The customer has no access to the meter which means that he cannot switch it on again directly. In this case the meter swiches on the load again automatically after the disconnection time has lapsed.

6.7.2 Load switching 6.7.2.1 Load switching via the call-up button Operation display
Via the menu option “LOAd OnIOFF” in the menu “Call-up button” the switching of the load can be carried out directly on the meter. By operating the call-up button 2 s < t < 5 s the submenu option “LOAd OFF” or “LOAd On” appears independent of the relay position. “LOAd OFF”: By operating the call-up button > 2 s the load is switched off. The display returns to the operation display. With a successful switching off, the display “OFF” appears. If the switching process failed, “LOAd Error” appears. The meter can still be operated.

6.7.2.2 Load switching via commands Switching on and off the load using a command takes place via the meters interfaces (D0, CL0, RS232, RS485, radio). 6.7.2.3 Manual load switching Release for the manual switching on of the load takes place via the meters interfaces (D0, CL0, RS232, RS485, radio). Release can be identified via the display “PrESS:On” .
The meter can no longer be operated in this condition. By operating the call-up button > 5 s the load is switched back on again. Afterwards the meter can be operated again as normal. 6.7.2.4 Load switching by means of excess load 6.7.2.4.1 Switching off by means of excess load When a fixed power threshold is exceeded the load us switched off. This threshold can be set and saved in the 1.35.0.01(). In the regiser 1.35.0.02() a “forewarning threshold” can be saved. When one of the thresholds is reached, this is signalised in the display by the sideward cursor “PWR”. If no thresholds are configured, no power monitoring takes place. Threshold monitoring takes place by means of the power instantaneous value 1.25. Switching off takes place after a fixed lag time as long as the power is exceeded for the whole of the lag time. If the switching off is successful, “OFF” appears in the display. The meter can still be operated. The power thresholds and the lag time can be set via the meters interfaces (D0, CL0, RS232, RS485, radio). 6.7.2.4.2 Automatic switching on If the load is switched off due to power monitoring, this is switched back on again after a fixed diconnection time. If no disconnection time is configured, the load is not switched back on automatically. The disconection time can be set via the meters interfaces (D0, CL0, RS232, RS485, radio).
6.7.3 Monitoring the switch off condition If the load is switched off, the meter checks its idle condition. If this is not given after the switching off, the meter repeats its power down process cyclically. When the idle condition is fulfilled, “OFF” appears in the display. If the switching off fails, “LOAd Error” appears in the display. Additionally an entry appears in the status for load switching C.86.8(). At the same time, a time meter is activated which records the hours in which the load was connected. The time meter can only be reset by deleting the measured data. Even if the switching off fails, the meter can still be operated and commands can be received. Note: A continuous base load above the meters response threshold is a requirement for the monitoring function.

6.8 Recording external measuring variables The LZQJ-XC is capable of ing other impulses from reference-, thermal-, wateror gas meters via 4 impulse inputs. From these inputs, energy values, maximum demand and load profiles can be formed. These measuring variables can then be read out via the LZQJ-XC meter.
Figure 40: Application plan - recording load profiles form other media
Figure 41: Diagram - Recording of load profiles from several meters
Pulse counting In order to avoid incorrect registration of pulses, the minimum pulse length and no-pulse period can be set in 5ms steps. Furthermore the activating edge (rising or falling) can be selected. A ed pulse is evaluated by means of a settable pulse constant and a unit.The quantums which are formed in this way can either be summed among eachother or added to or subtracted from the measuring variables formed internally in the meter. When an input pulse constant is changed, an entry is made in the certification relevant log book P.99 (see 5.2.7 Certification relevant log book (menu option “P.99”)). All measuring variables resulting from this are available as an input channel for the energy- and maximum demand s and for the load profile formation.
88
Example: Via the pulse input with the channel number 2, active power proportional pulses are counted. These are then added to the variables formed in the meter and ed in separate meter s with the channel number 13 (see also 8.1 OBIS (ObjectIdentification-System)). OBIS code

Shortened no-load test LED is continuously lit-up = no load, energy direction arrows are not displayed Shortened start-up test The LED starts to flash. The energy direction arrows display the measured energy direction.
7.2 Test load Test loads for testing meters which have several nominal voltages (long-range) or 1 a nominal voltage range This test is to be carried out at the upper and lower voltage rate which is specified on the nameplate, provided no other conditions are specified in the approval. Test loads for testing meters which have two nominal currents
1
With the test of meters with two nominal currents (e.g. 5||1 A) the lowest test point (5% or 10%) is measured with the smaller nominal current. All other test points are measured using the higher nominal current. Testing of meters with two energy directions
1
As long as no other regulations are specified in the approval documents meters which measure energy in both directions are measured in a way as if two separate meters for import and export are being dealt with.

8.4 Software 8.4.1 EMH-COM EMH-COM is a modular developed software which enables communication between a readout device (e.g. PC or laptop) and EMH meters. The software is designed especially for starting up the meter, reading out data from the meter and also for changing the basic settings. Due to the modular set-up, the software can be tailored directly to the customer’s requests.

8.4.3 EMH-Mobile EMH-Mobile is a mobile and manageable tool for starting up and reading out electricity meters on location. EMH-Mobile consists of a PDA (Personal Digital Assistant) and an optical communication adapter (Bluetooth-OKK). With both devices, a wireless communication is possible via a Bluetooth-interface
Figure 42: EMH-Mobile
The software EMH-Mobile is installed on the PDA for communication with meters. Special features of the software include “Installation check” (possible with all EMH meters with a service table) and also the readout of electronic household meters eHZ. Via the “Installation check” the meter connection can be easily checked. Connection errors can therefore be detected on location.

8.5.2 Possibilities of meter communication In the following, the communication between a readout device and a meter via the optical- or electrical interface are described.
8.5.2.1 Communication via optical interface The optical communication adapter OKK enables communication between a readout device (e.g. PC or laptop) and EMH meters. On the meter the connection is to the optical data interface D0 and on the PC, depending on the version, the connection is to a COMport or to a USB interface. Connection of the OKK: Connect the optical communication adapter OKK to a free COM-Port or a free USB interface on your PC. If you have an OKK with USB connection then a special USB driver must be installed. The driver can be found on the CD-ROM which is included in the delivery with the OKK. Tips for the installation of the driver can also be found on the CD-ROM. Note: Before communication can take place with the meter the interface must be configured under “Setting” > “Program settings...” >. (see 8.5.3.1 General settings).
8.5.2.2 Communication via electrical interface Communication with the meter via the connection PC-modem-meter modem (remote meter read out) requires the definition of some parameters (see 8.5.3.2 Modem).
