Safety Notes
• The actuator is not allowed to be used outside the specied eld of application, especially in aircraft
or any other form of air transport.
• 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 specications supplied by the damper manufacturers
(cross section, design, installation site), and the air ow conditions must be observed.
• 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.

Mode of Operation
The actuator is controlled by means of a standard control signal DC 0 ... 10 V. It opens to the
position dictated by this signal. The measuring voltage U allows the damper position (0 ... 100%)
to be electrically indicated and serves as a follow-up control signal for other actuators.
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 operation is possible with the self-resetting pushbutton (the gearing latch remains
disengaged as long as the pushbutton is pressed).
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.
