7 Troubleshooting
•
When servicing, do not touch meter connectors directly with bare hands, metal, bare wires or other conductive
material; it could cause an electric shock and result in serious injury or death.
•
Before opening the protective cover, switch off all power sources of the energy meter and the devices connected to it
and, if possible, lock them.
•
Work on the devices may only be carried out by qualified specialist personnel who are familiar with the applicable rules
and regulations.
•
Use insulated tools when servicing or repairing the meter.
•
Be sure to put the protective cover back on after maintenance or repair.
•
The enclosure is sealed and must not be opened; failure to follow this instruction may result in damage to the meter.
Problem
The red consumption LED on the
front does not flash.
The counter does not count.
No pulse output
If none of the above works, please contact technical support.
7.1 Error / Diagnostic Indication
All measured values are stored twice with the associated checksums. If the checksum fails, the backup data is used.
If both normal storage and backup fail, the meter will stop working and display error XX:
XX is the hexadecimal data; convert the data to binary values to analyze the data.
bit0: Data in the main memory and in the backup area of the accumulator is incorrect and cannot be used.
bit1: The mantissa area of the accumulator cannot be operated.
bit2: The backup area of the accumulator cannot be operated.
bit3: The main memory area of the accumulator cannot be operated.
bit4: Data error in the mantissa area of the accumulator
bit5: Data error in the battery backup area (integer bit)
bit6: Data error in accumulator main memory area (integer bit)
bit7: EEPROM cannot be fully initialized.

Notice
Warning
Possible Cause
There is no load connected to the meter.
The load on the line is very small.
There is no load connected to the meter.
The pulse output is not supplied with DC
voltage.
The pulse output is not correctly connected.
Testing / Solution
Connect a load to the meter. Use an ohmmeter
to check if the load reading is very low.
Check that the red consumption LED is
flashing.
Use a voltmeter to check whether the external
voltage source (U
) is 5 ... 27 VDC. Check
i
whether the connection is correct: see Section
6.6.3 S0 Pulse Output
