Remedies for the resolution of faults
Fault Remedies
Device is not working
• Check power supply
• Check supply voltage
• Check fuse
Voltage or current measured values are not
displayed
• Check fuse
• Check configuration
(see Parameterizing the device (Page 54))
Voltage values are not plausible
• Check the voltage transformer setting and correct if necessary
Current values are not plausible
• Check the current transformer setting and correct if necessary
No communication
• Check the communication settings
(incorrect IP address, incorrect subnet or gateway?)
• Check firewall, if present
(possibly preventing communication to the Modbus ports)
"Overload" LED flashes red
• Voltage or current input overridden. Check parameters of the
measuring voltage
• Check installed current transformer
(dimensioning too small)
Power values are incorrect, although voltage
and current are correctly applied
• Check voltages and currents of the phases
(not properly connected to one another)
• Check the current transformer
(for incorrect polarity)
If the device fault cannot be remedied by the measures given above, the device is probably
defective.
