The module displays the relevant fault depending on the parametrizing. The analogue output
signals, however, will be processed further.

An analogue output module can register the following faults:
Description
Short circuit/overload in voltage
1)
supply
Only with voltage outputs with signal
range 0...10 V:
Short circuit/overload at an output
(see Parameters Monitoring the
CPX module monitoring short cir
cuit/overload at output").
The reaction depends on the parame
trizing, parameter Behaviour after
short circuit/overload at output":
Setting Leave voltage/current
switched off":
The output is switched off.
Setting Switch on voltage/current
again":
The output current is limited to
approx. 15 mA.
Fault treatment
1. Check actuators, eliminate short
circuit/overload (number of faulty
channel: see LED display or module
diagnostic data).
2. Depending on parametrizing:
