UMG 604
Possible error
Displayed
voltage
is too small or too
large.
Displayed
voltage
is
too small.
“
EEEE” and “V”
in the display.
„
Error CF
„ in the dis-
play
Active power
con-
sumption / supply is
reversed.
Cause
Measurement in the wrong phase.
Voltage transformer incorrectly
programmed.
Overrange.
The peak voltage value at the mea-
surement input has been exceeded
by harmonic components.
The voltage measuring range has
been exceeded.
The calibration data could not be
read out.
At least one current transformer
connection is mixed up/reversed.
A current path is assigned to the
wrong voltage path.
Remedy
Check connection and correct if
necessary.
Read out and program the voltage
transformer transformation ratio
at the voltage transformer.
Install voltage transformers.
Important!
Ensure the
measurement inputs are not
overloaded.
Check the measuring-circuit
voltage and if necessary install
a suitable voltage transformer.
Send device to the manufacturer
for checking with a precise
description of the error.
Check connection and correct if
necessary.
Check connection and correct if
necessary.
