Fault Messages Of The Analogue Input Modules - Festo CPX-AB Series Electronic Manual

2. Analogue input module CPX−2AE−U−I

2.5.1 Fault messages of the analogue input modules

Fault Description
number
2 Fault short circuit/overload
Short circuit/overload in sensor supply
(V
EL/SEN
(See Parameters" Monitoring the
CPX module monitoring short circuit/
overload at sensor")
3 Wire fracture at current input
Only with voltage inputs with signal range
4...20 mA:
The input currennt I
(See parameter Monitoring channel x
monitoring of wire fracture")
Less than the rated range
9
Lower limit exceeded.
(See parameter Lower limit channel x
low byte/high byte" or Monitoring
channel x monitoring below rated
range")

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

Fault treatment
1. Eliminate short circuit/overload or
check connected sensors
2. Depending on parametrization (Para
meters Behaviour after short circuit/
overload"):
Setting Switch on voltage again":
·
Power supply for sensors will be
switched on again automatically
when short circuit is eliminated.
Setting Leave voltage switched off":
·
Power off/on necessary
or
Modify parameter Behaviour
after short circuit/overload" to
Leave voltage switched off".
Check and, if necessary, replace the
·
cable and connected sensors.
Check signal range of input.
·
Check input signal present.
·
Check parametrized limit.
·
If necessary, deactivate monitoring.
