1) 2)
A fault has occurred in the setting of
the relevant parameter.
Parameter data format
Parameter lower limit
Parameter upper limit
·
Check the parametrizing undertaken
and, if necessary, undertake the
parametrizing again with the correct
parameters.
The analogue output module will be
operated further with the last valid
parametrizing.

F au l t in actuat or su pply
1)
Short circuit/overload or undervoltage
in actuator supply (V
OUT
).
(See parameter Monitoring the CPX
module monitoring short circuit/
overload at output")
Setting Leave voltage switched off":
The actuator supply is switched off.
Setting Switch on voltage again":
The output current is limited to
approx. 250mA.
1. Eliminate short circuit/overload or
check actuator supply, if necessary,
check connected actuators
2. Depending on parametrizing
(parameter Behaviour after short
circuit/overload at output"):
·
Power off/on necessary (load volt
age supply for outputs V
OUT
), or
change parameter
Behaviour after short circuit/
overload at output" to Switch
voltage on again".
·
If the actuator current supply is
less than 400mA:
The voltage will be switched on
again
aut o matica lly when the
short circuit is eliminated.
If the actuator current supply is
more than 400mA:
Power off/on is necessary (V
OUT
).
1)
The module displays the relevant fault depending on the parametrizing. The analogue output
signals, however, will be processed further.
2)
The parameters entered will be ignored, the module operates with the last valid parameters.
