The actuator is connected to this plug. The actuator voltage goes to the piezo, the position signal
from the measurement system goes to the DSP, and the integrated actuator information is stored
on an ID-chip which goes to the main controller. It is important that the locking screws are screwed
into the front panel. The voltages will be switched after connecting the actuator. When
disconnecting the actuator, the dangerous Voltages will be switched off by a safety relay.
