If this fault occurs again: check and, if
necessary, replace the analogue input
module.

·
Check the parametrizing undertaken
and, if necessary, undertake the
parametrizing again with the correct
parameters (valid parameters see
section 2.4.3).
The analogue input module will be
operated further with the last valid
parametrizing.
1)
The module displays the relevant fault depending on the parametrizing. The analogue input
signals, however, will be processed further.
2)
Processing of the analogue input signals will be stopped.
3)
The parameters entered will be ignored, the module operates with the last valid parameters.

Please note the following when using the input modules:
If there is a short circuit, all sensor supplies of the
module will be switched off t og et h e r .
If not parametrized otherwise, the sensor supply voltage
will be switched on again aut o matica lly when the short
circuit is eliminated.
