During a forced operation, the Switch Actuator triggers a freely adjustable forced position. This has the
highest priority, i.e. it is not modified by a valve purge or safety position.
Forced operation can be
activated via communication object
Forced operation = "1"
and
deactivated via
Forced operation = "0"
.

Options:
unchanged
0% (closed)

The valve position triggered by the actuator during the forced operation is determined by this parameter.
The value in brackets corresponds to the 1 byte value.
The switch cycle time t

in parameter window
A: General.
When forced operation ends the Switch Actuator returns to its normal method of operation and calculates
its next contact position value from the incoming values on communication objects
