Error Messages Of The Anaolgue Output Modules - Festo CPX Series Manual

8. Analogue output module CPX-2AA-U-I

8.5.1 Error messages of the anaolgue output modules

Error number
2
1)
The module displays the relevant error depending on the parameterisation. The analogue output
signals, however, will be processed further.

An analogue output module can register the following errors:
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 paramet-
erisation, 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.
Error treatment
1. Check actuators, eliminate short
circuit/overload (number of faulty
channel: see LED display or module
diagnostic data).
2. Depending on parameterisation:
(Parameter "Behaviour after short
circuit/overload at output")
•
Power off/on necessary
(operating voltage supply for
electronics/sensors V
change parameter "Behaviour
after short circuit/overload at
output" to "Switch voltage on
again".
•
The voltage will be switched on
again automatically when the
short circuit is eliminated.
