2-wire open-close control. The actuator is overload-proof and
can thus remain energized even at the end stops.
Two microswitches with fixed settings are installed in the
actuator for indicating the damper end positions. The position
of the damper blade can be read off on a mechanism position
indicator.
The crank handle supplied with the actuator allows it to be
operated manually.
