Operating Instructions, 11/2018, A5E03071515-AE
Description
coil circuit and electro‐
des. An insulation fault
will result in a offset er‐
ror on flow measure‐
ment
(Advanced version on‐
ly)
Error in the coil circuit.
Coil current has not set‐
tled within specified pe‐
riod.
A short-circuit in the coil
can NOT be detected
Input signal is outside
expected range.
Input amplifier circuit
can not provide a stable
measurement.
A short circuit between
the two electrodes or
between a electrode
and common can NOT
be detected
Cause
● Defect cables between
sensor and transmitter
● Wrong connections of
remote cables
● Water between coils
and electrodes – could
be caused by a broken
liner
● Pollution/moisture on
PCB caused by water in
encapsulation
● Coils have been
disconnected could be
caused by broken cable
or wires
● Electrodes have been
disconnected, or
connected to ground
Remedy
Check cable and wiring installation and dis‐
turbing elements in the surrounding.
Re-activation of insulation test (parameter
800) will reset alarm and start a new insu‐
lation test.
During the 4 minute insulation test, meas‐
urement is disabled.
Alarm remains active until a new test period
detects no failures.
Check cable and wiring installation.
Alarm remains active until the fault condi‐
tion is corrected.
