General
The Interface Module XC is designed for use with the EMH LZQJ-XC and DMTZ-XC meters. The module is equipped with an M-Bus (2 wires) interface. The module can be plugged easily into the module compartment of the meter. It can be mounted or exchanged during operation (without breaking approval seal). An integrated M-Bus interface (Protocol Converter to DIN EN 13757-3) provides a simple means of connecting multi-energy meters. This makes multi-energy applications an affordable proposition for domestic use. Due to the communication, the modules are suitable for a lot of control centres.
Compatible meters
LZQJ-XC (special meter for industrial applications):
- Standard meter for direct connection
- Transformer connection version Cl. B (Cl. 1)
- Precision meter Cl. C (Cl. 0.5S)
- Precision meter Cl. 0,2S
DMTZ-XC (residential meter)
Functions
M-Bus interface (2 wires, passive) for bi-directional
communications; Alternative: BFC-Bus (BAER Field Control, 56VDC);
Transmission protocol: M-Bus (DIN EN 13757-3:2013-08);  Internal communication interface for the transfer data
between the meter and the interface module (service data list / table TS);
Protocol converter for meter data into M-Bus-Format
(non transparent data readout);
Internal power supply from meter;  Exchangeable during the meter operation;
The owner of the interface modules is responsible that all persons engaged on work with the modules:
• Are competent and qualified in accordance with national regulations (see ISSA "Guideline for Assessing the Competence of Electrically Skilled Persons").
• Have read and understood the relevant sections of the user manual.
• Strictly observe the safety regulations (according to the following section) and
the instructions in the individual chapters.
Safety Notes
The owner of the modules is also responsible for:
• The protection of persons.
• The prevention of material damage.
• The training of personnel.
The following safety regulations must be observed at all times:
• Devices which have fallen down should not be installed, even if no damage is apparent, and should be returned for testing to an authorised service centre (internal damage possible).
• Modules must never be cleaned with running water or high pressure devices. Water can cause
short-circuits or damage el. components.

Work on electrical installations and equipment may only be performed by adequately trained
qualified and in conformity with the applicable national rules and regulations.
Strictly observe the safety regulations!
Installation of the interface module:
1. Check the interface module.
2. Remove the terminal cover [5].
3. Open the transparent module cover [1].
4. Insert the interface module [3] carefully at the place provided in the meter [2].
5. Push the module in to the internal contacts.
6. Connect the cable.
7. Close the transparent module cover [1].
8. Close the terminal cover [5].
Removing of the interface module:
9. Remove the terminal cover [5].
10. Open the transparent module cover [1].
11. Disconnect the cable.
12. Remove the interface module.
13. Close the transparent module cover [1].
14. Close the terminal cover [5].

Installation Hints
The installation must be done in a way, that even in the case of cable break no dangerous voltages are applied to touchable parts of the module. Generally, meters are delivered with the communication modules installed. The fitting of a meter with a communication module is, therefore, an exception and can be necessary e.g. when a module needs to be replaced.
The interface module is exchangeable during the meter operation. Fit the interface module in the meter as follows:
LED Displays
Three LED’s display the current operating status of the module and give information about the data transfer.

Communication (M-Bus, Protocol Converter)
The M-Bus interface is conforming to DIN EN 13757-3:2013-08. Fixed baud rate from the 2nd electrical interface (see EMH COMBI-TOOL-Software: communication interfaces, set please the data transmission at a fixed baud rate without baud rate changeover), data format: 8E1; For configuration purposes of the service table TS please contact the meter manufacturer or operators.
Parameterisation of the meter (EMH COMBI-TOOL-Software)
At the first read the read all data from the meter (via optical IR interface):
Baud rate
The Interface Module XC uses the same baud rate like the communication interface at the meter. For setting use please the EMH COMBI-TOOL-Software: Menu Meter Interfaces Electrical interface:
For correct working set please a fixed bad rate (e.g. 9600 baud). If you use the baud rate changeover according to mode C: the communication is possible with 300 baud only. For the addressing set the value “optionally” or “ignore”. Note: In many M-Bus systems is the standard baud rate 2400 baud.
Reset
Note: The EMH LZQJ-XC meter performs automatically a daily reset at 00:00 in the interface module.

Service Data List / Table TS and M-Bus-Address
For setting the meter data list use menu Lists Reading lists Service Table TS:
Note: The M-Bus module XC uses for ID-Addresses the OBIS Register 0.0.0 (secondary address) and 0.0.1 (primary address) in the service data list TS. In this example we use the identification number 1 (OBIS 0.0.1) for M-Bus primary address: menu Meter Meter ID OBIS Register 0.0.1, e.g. value 123 (:= 00000123):
Standards for M-Bus addresses:
Primary address: OBIS Register 0.0.1 (Identification 1), range 0 to 250, default := 1 Secondary address: OBIS Register 0.0.0 (device number / fabrication number), range 0 to
99999999, default := 0
For determining the address it is possible to use the wildcard searching procedure (answer E5
Hex
).

Accepting the meter data (OBIS-Registers)
The Interface Module XC reads the service data list / table (TS) from the meter periodically (interval between two readings: ca. 1 second) and creates an internal table. The OBIS coded values from the meter will be convert to the M-Bus data. This version of the implementation supports following OBIS-Registers: Energy: Counter values for active, reactive and apparent energy (OBIS-Registers 1.8.x, 2.8.x,
3.8.x, 4.8.x, 5.8.x, 6.8.x, 7.8.x, 8.8.x, 9.8.x and 10.8.x).
Power: Instantaneous values (average) for active and reactive power, voltage, current and line
frequency (OBIS-Registers 1.25 at seq., 3.25 at seq., 11.25 at seq., 12.25 at seq. and 14.25); Last average value for active and reactive power (OBIS-Registers 1.5.t, 2.5.t, 3.5.t and 4.5.t).
Possible OBIS-Registers in the service data list / table TS:
