Levelflex M FMP43 with PROFIBUS PA
Troubleshooting
Hauser
83
A261
HF cable defective
HF cable defective or HF connector loose
check HF connector, replace cable if
defective
W275
offset too high
temperature at the electronics too high or
HF module defective
check temperature, replace HF
module if defective
W512
recording of mapping -
please wait
recording active
wait a few seconds until alarm
disappears
W601
linearization ch1 curve not
monotone
linearization not monotonously increasing correct linearization table
W611
less than 2 linearization
points for channel 1
number of entered linearization points < 2 correct linearization table
W621
simulation ch. 1 on
simulation mode is active
switch off simulation mode
E641
no usable echo
channel 1
check calibr.
echo lost due to application conditions or
buildup on probe
check basic setup;
clean probe (see Operating
Instructions, Troubleshooting)
W650
signal/noise ratio too low
or no echo
noise amplitude too high
eliminate electromagnetic
interference
E651
level in safety distance - risk
of overfill
level in safety distance
alarm will disappear as soon as level
leaves safety distance
perform reset where necessary
A671
linearization ch1 not
complete, not usable
linearization table is in edit mode
activate linearization table
W681
current ch1 out of range
current out of range
(3.8 mA to 21.5 mA)
check basic setup and linearization
