Active power too
small / too large.
Active power draw-
ing / supply re-
versed.
„EEEE A“ in the
display.
„EEEE V“ in the dis-
play.
Digital output or
pulse output do not
react.
Despite the above
measures the de-
vice still doesn‘t
work.
Cause
The battery is dead.
The device has been ex-
posed to electromagnetic
interferences, which are
greater than those given in
the technical specifications.
The current transformer
conversion ratio is incor-
rectly programmed. Cur-
rent circuit assigned to the
wrong voltage circuit.
Current at the measure-
ment input lies outsite the
measuring range.
Voltage transformer conver-
sion ratio is incorrectly pro-
grammed.
Voltage at the measure-
ment input lies outside the
measuring range.
At least one current trans-
former connection is re-
versed. Current circuit is
assigned to the wrong volt-
age circuit.
The current measuring
range has been exceeded.
The voltage measuring
range has been exceeded.
No source has been as-
signed to the output.
device defekt.
Remedy
Send the device to the manufacturer for a
battery replacement.
Take external protective measures, e.g.
screening, filtering, earthing or spatial
separation.
Read off and program the current trans-
former conversion ratio at the current
transformer. Check the connection and
correct if necessary.
Install larger or smaller current trans-
former.
Read off and program the voltage trans-
former conversion ratio at the voltage
transformer. If the voltage is not meas-
ured using a voltage transformer, pro-
gram voltage transformer 400/400.
Install larger or smaller voltage trans-
former.
Check the connection and correct if nec-
essary.
Check the connection and correct if nec-
essary.
Check the measured current and if nec-
essary install a suitable current trans-
former.
Check the measured voltage and if nec-
essary install a suitable voltage trans-
former.
Program the output.
Send the device to the manufacturer for
checking, with a precise description of the
fault.
