Preparing for installation

Four M4 screws are included in the delivery for mounting the rotary drives.

The drives are constructed so they are axially symmetrical. In case of a spring-return function, the safety position must be selected on site by turning the drive through 180°. It is also important to remember that the drives have a total positioning angle of approx. 95° in order to pre-tension the actuator (air damper or similar). Pre-tensioning is only appropriate if the rotary drive should close the actuator. In this case, the 5° ensures the actuator is closed with “outlet pressure”.

Pre-tensioning must be calibrated mechanically via the manual adjustment “HV” before the rotary drive is mounted on the drive axle. The hexagonal Allen key must be turned anticlockwise if looking from the “R side” of the rotary drive, or clockwise if looking from the “L side”. The symbol next to the “HV” socket shows the direction of rotation.

Determine installation position for the rotary drive and prepare device

  1. Determine whether the rotary drive should close or open your air damper or valve.
  2. Check the direction of rotation for the drive axle on your device, which will be the means of reaching the final position. Use a spanner for this if applicable.
  3. This will enable you to determine the position in which the rotary drive needs to be installed. The picture above shows the correct installation position if the drive axle needs to be turned to the left to reach the desired final position.
  4. Make sure your device is in the desired final position (open or closed).
