Error Messages Of The Analogue Input Modules - Festo CPX Series Manual

3. Analogue input module CPX-4AE-U-I

3.5.1 Error messages of the analogue input modules

Error no. Description
2 Error short circuit/overload
Short circuit/overload in sensor supply
(V
EL/SEN
(see parameter "Monitoring the CPX
module – monitoring SCS" in Tab. 3/7)
Wire break at current input
3
Only for voltage inputs with signal
range 4 ... 20 mA: The input current I
is less than 1.2 mA.
(see parameter "Monitoring channel x
– monitoring wire break")
9 Value below nominal range
Lower limit exceeded.
(see parameter "Lower limit channel x
– low byte/high byte" or "Monitoring
channel x – monitoring value below
nominal range")
1)
The module will report the appropriate error depending on the parameterisation. The analogue
input signals will, however, be processed further.

The CPX-4AE-U-I module can register the following errors:
1)

Error handling
1. Eliminate short circuit/overload or check
connected sensors
2. Depending on parameterisation (para-
meter "Behaviour after short circuit"):
Setting "Switch voltage on again":
•
Power supply for sensors will be
switched on again automatically when
the short circuit is eliminated.
Setting "Leave voltage switched off":
•
– Power Off/On necessary
or
– Modify parameter "Behaviour after
short circuit" to "Switch voltage on
again".
Check and, if necessary, replace the cable
•
and connected sensors.
IN
Check signal range of input.
•
Check input signal present.
•
Check parameterised limit value.
•
If necessary, deactivate monitoring.
