3.2.1
Normal operation
The actuator opens or closes the valve depending on
the applied control voltage.
The actuator can be adapted to the specific parame-
ters of the valve used with the help of DIP switches.
3.2.2
Emergency end position
The actuator features an energy store.
If the operating voltage fails, the stem of the actuator
