7.3 Troubleshooting guide
Fault
No communication
Power values are incorrect, although voltage and current are
correctly applied
Fault indication in the display menu:
"MID VOID"
If the device fault cannot be remedied by the measures given above, the device is probably
defective.
More help can be found on the Internet.

Remedies
• Check the network cable connection
• Check whether the green "LAN" LED is lit
• Check the communication settings (incorrect IP address,
incorrect subnet, incorrect Modbus TCP port or gate-
way?)
• Check firewall, if present (possibly preventing communi-
cation to the Modbus ports)
• Check voltages and currents of the phases (not properly
connected to one another)
• Check the polarity of the current transformer, if present
For devices with a current transformer connection:
Incorrect phase assignment between voltage and current
connections:
– Check voltages and currents of the phases (not
properly connected to one another) and correct if
necessary.
– The voltage tap for connection of measuring voltage
UL1 must be performed at the same phase as the in-
stallation of the current transformer that is connected
to the IL1 terminals.
The same applies to voltage tap UL2 and the current
transformer at IL2, as well as voltage tap UL3 and the
current transformer at IL3.
– Check the current flow direction of the primary cur-
rent transformers and the wiring of the secondary
connections (k,l) of the current transformers and re-
place if necessary.
