• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.
The actuator is controlled with a standard modulating signal of DC 0 ... 0 V and travels to the
position defined by the control signal. Measuring voltage U serves for the electrical display of the
damper position 0 ... 00% and as slave control signal for other actuators.
Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an
anti-rotation strap to prevent the actuator from rotating.
Manual override with push-button possible (the gear is disengaged for as long as the button is
Manual override
pressed or remains locked).
Adjustable angle of rotation with mechanical end stops.
The actuator is overload-proof, requires no limit switches and automatically stops when the end
stop is reached.
