1)
Only with current outputs with signal
range 0/ 4...20 mA:
The wire−fracture monitoring is only
effective if more than approx. 1 mA
output current is output.
(See parameter Monitoring channel x
monitoring wire fracture/idling")
·
Check and, if necessary, replace the
cable and connected actuators.

Lower limit exceeded.
(See parameter Lower limit channel x
low byte/high byte" or Monitoring
channel x monitoring below rated
range")
·
Check signal range of output.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.

1)
Upper limit exceeded.
(See parameter Upper limit channel x

·
Check signal range of output.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.

2)
General fault, module faulty.
·
Power off/on necessary
·
If this fault occurs again: check
and, if necessary, replace the
analogue output module.
Evaluation of the analogue output
signals has stopped.
1)
The module displays the relevant fault depending on the parametrizing. The analogue output
signals, however, will be processed further.
2)
Processing of the analogue output signals will be stopped.
