3. Analogue input module CPX−4AE−I
Fault Description
number
10 Rated range exceeded
Upper limit exceeded.
(See parameter Upper limit channel x
low byte/high byte" or Monitoring
channel x monitoring rated range
exceeded")
15 Module/channel failed
General fault, module faulty.
Fault in parametrizing
A fault has occurred in the setting of the
relevant parameter.
21 Parameter data format
24 Parameter lower limit
25 Parameter upper limit
(See parameter Monitoring the CPX
module monitoring parametrizing fault"
or Monitoring channel x monitoring
parametrizing fault")
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
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 together.
If not parametrized otherwise, the sensor supply voltage
will be switched on again automatically when the short
circuit is eliminated.
Fault treatment
Check signal range of input.
·
Check input signal present.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.
·
Power off/on necessary
·
If this fault occurs again: check and, if
·
necessary, replace the analogue input
module.
Evaluation of the analogue input signals
has stopped.
Check the parametrizing undertaken
·
and, if necessary, undertake the
parametrizing again with the correct
parameters (valid parameters see
section 3.4.3).
The analogue input module will be
operated further with the last valid
parametrizing.
