janitza UMG 508 - Metering range overload

83
UMG 508
Possible errors
Metering range ex-
ceedance (overload)
Effective power is
too high or low.
Effective power-
receipt/supply are
mixed up.
Cause
Voltage or current input out
of range (see chapter mete-
ring range exceedance)
The programmed current
converter transfer ratio is
wrong.
The current path is allocated
to the wrong voltage path.
The programmed voltage
converter transfer ratio is
wrong.
At least one current conver-
ter connection is mixed up.
A current path is allocated to
the wrong voltage path.
Remedy
Check and correct the connection if
necessary.
Use suitable voltage or current trans-
formers.
Read and program the current or voltage
transformer ratio on the transformer.
Read and program the current conver-
ter transfer ratio on the current conver-
ter.
Check the connection and correct if
necessary.
Read and program the current conver-
ter transfer ratio on the current conver-
ter.
Check and correct the connection if
necessary.
Check and correct the connection if
