Safety notes
!• The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or any other form of air transport.• Caution: Power supply voltage!• Assembly must be carried out by trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.• The device may only be opened at the manufacturer‘s site. It does not contain any parts that
can be replaced or repaired by the user.• The cable must not be removed from the device.• When calculating the required torque, the specifications supplied by the damper manufacturers
(cross section, design, installation site), and the air flow conditions must be observed.

Product features
Simple direct mounting 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 Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).
Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.
High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
Flexible signalization Flexible signalization with adjustable auxiliary switch (0 ... �00%).
