5. Multi I/O modules
Error number Description
2 (continuation) – Short circuit/overload at the output
(see "Parameters" "Monitoring the
CPX module – monitoring short cir-
cuit/overload").
The reaction depends on the para-
metrization, Parameters "Reaction
after short circuit":
– Setting "Leave voltage switched
off":
The output is switched off
– Setting "Switch on voltage
again":
The output current is limited to
approx. 250 mA.
5 Fault in load voltage for outputs

missing or too low.

Please note
Please note when using the multi I/O modules:
– If there is a short circuit, all sensor supplies 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.
Error treatment
1. Check actuators, eliminate short
circuit/overload (number of faulty
channel: see Module diagnostic
data).
2. Depending on parametrization:
(Parameters "Reaction after short
circuitat output").
Set output to 0, then set to 1
•
again (Default), or modify Para-
meters "Reaction after short
circuit at output" to "Switch
voltage on again".
If the output current is lower
•
than 400 mA:
The voltage will be switched on
again automatically when the
short circuit is eliminated.
If the output current is greater
than 400 mA:
Set output to 0, then set to 1
again (default).
Check the load voltage
