Function Of The Output Modules - Festo CPX Electronic Manual

4. Output modules

4.5.1 Function of the output modules

Error number Description
2 Short circuit/overload
Short circuit/overload at the output
(see "Parameters" "Monitoring the CPX
module – monitoring short circuit at the
output").
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
Load voltage for outputs (V
missing or too low.

Error treatment
1. Check actuators, eliminate short
circuit/overload (number of faulty
channel: see LED display or module
diagnostic data).
2. Depending on parametrization:
(Parameters "Reaction after short
circuit at 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
