Features
 

• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and moves to the position defined by the control signal. The measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave 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 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. A minimum permissible angle of rotation of 30° must be allowed for.



• High functional reliability  The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.



• Home position When the supply voltage is switched on for the first time, i.e. at commissioning or after pressingthe „gear disengagement“ switch, Pos. Direction of rotation switch Home positionY = 0 Left stop1 Y = 0 Right stop the actuator travels to the home position.The actuator then moves into the position defined by the control signal.


• Adaption and synchronisation During adaptation, the upper and lower spindle end stop is recorded and deposited in the actuator. Detection of the mechanical end stops enables a gentle approach to the end positions and thus protects the actuator mechanism.During synchronisation, the actuator moves to the home position for angle referencing. This ensures correct position regulation.
