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.

Description
Wire fracture/idling
1)
Current output
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")
Less than the rated range
Lower limit exceeded.
(See parameter Lower limit channel x
low byte/high byte" or Monitoring
channel x monitoring below rated
range")
Rated range exceeded
Upper limit exceeded.
(See parameter Upper limit channel x
low byte/high byte" or Monitoring
channel x monitoring rated range
exceeded")
Module/channel failed
General fault, module faulty.
Fault treatment
Check and, if necessary, replace the
·
cable and connected actuators.
1)
Check signal range of output.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.
·
1)
Check signal range of output.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.
·
2)
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.
