9.1 Fault codes
Error system
MAG 8000 can detect and report 14 different faults.
The faults are divided into two types: Fatal errors and Warnings.
Fatal errors: Faults 1, 2, 3, and 4
Warnings: Faults 5, 6, 7, 8, 9, L, E, C, d, and 14
Fault
codes
Name/text 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
disconnected 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
connected to ground
Check cable and wiring installation.
Alarm remains active until the fault condi‐
tion is corrected.
