Fault number Description
Fault in parametrizing
A fault has occurred in the setting of
the relevant parameter.

module monitoring short circuit/
overload at output")
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.

Setting Leave voltage switched off":
The actuator supply is switched off.
Setting Switch on voltage again":
The output current is limited to
approx. 250 mA.
Fault treatment
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.
1. Eliminate short circuit/overload or
check actuator supply, if necessary,
check connected actuators

less than 400 mA:
The voltage will be switched on
again automatically when the
short circuit is eliminated.
If the actuator current supply is
more than 400 mA:
Power off/on is necessary (V
