Description
Cause
Remedy
1
Insulation fault "Cross-talk" between
coil circuit and electro‐
des. An insulation fault
will result in a offset er‐
ror on flow measure‐
ment
(Advanced version on‐
ly)
● 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
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.
2
Coil current
fault
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
● Coils have been discon‐
nected could be caused
by broken cable or wires
Check cable and wiring installation.
Alarm remains active until the fault condi‐
tion is corrected.
3
Amplifier over‐
load
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
● Electrodes have been
disconnected, or con‐
nected to ground
Check cable and wiring installation.
Alarm remains active until the fault condi‐
tion is corrected.
