Display shows Kind of errors Measures
Err 01 EEPROM error Please contact technical support for a
meter replacement.
Err 02 Program code checksum error Please contact technical support for a
meter replacement.
Problem Possible cause Check/solution
The red consumption LED is not ashing
(PULSE LED).
There is no load connected to the
meter. The load on the line is very low.
Connect a load to the meter. Check with
an Ohm-meter if the load value is very
low.
The register doesn’t count. There is almost no load connected to
the meter.
Check if the red consumption LED is
ashing.
No pulse output. The pulse output is not supplied with
DC power. The pulse output is not con-
nected correctly.
Check the external voltage source (Ui) is
5-27V DC with a voltage meter. Check if
the connection is correct: the 5-27V DC
should be connected to the collector
connection (pin 20+) and the signal wire
(S) to the emitter connection (pin 21-).
The pulse output rate is wrong. Is the correct pulse rate set via the
infrared software or in Program mode 3?
Download or request the software
and use the infrared eye which can be
bought seperately.
If none of the above works, please contact technical support

A3.1 Communicating via the Modbus output
The meter can communicate with your PC. In order to read out the meter registers rst install and congure the PC software. Use
an RS485 level converter to connect the PC and the meter. The cable should be connected to terminals 10 and 11. The default
communication address of the meter is 01.
TheEx9EMS1P2M 100A MO 2T can be connectedforModbuscommunication.TheModbusimplementation used is Modbusbasic
(standard). This means the following:
• Baud rate 9600
• 8 data bits
• even parity
• 1 stop bit
The baud rate can be lowered to values 4800, 2400, 1200. The parity can be set to none or odd. Data and stopbit
cannot be changed.
When connecting the meter through a serial converter (RS485) for testing, please be aware that because of not
implementing the complete Modbus infrastructure, there will be a need to put an additional resistor (120 ohms/ 0.25 watts)
across the terminals (10 & 11) on the meter side.
For the registers used in the meter and how to interpreted the data, please use the Modbus register map on the next pages.
