Troubleshooting

Problem Probable cause Possible solution

The red consumption LED is not flashing (Pulse LED).

There is no load connected to the meter.

Connect load to the meter.

The load on the line is very low.

Check with multimeter, if the load value is very low.

The register does not count.

There is almost no load connected to the meter.

Check if the red consumption LED is flashing.

No pulse output.

The pulse output is not supplied with DC power. The pulse output is not connected correctly.

Check the external voltage source (Ui) is 5 – 27 V DC with a voltmeter. Check if the connection is correct: the 5 – 27 V 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 Modbus tool or in Program mode 3?

Use the Modbus tool which can be bought separately.
