Features

• 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 on the damper spindle with a universal spindle clamp (∅ 6 ... 12.7 mm). The actuator is then secured with the anti-rotation strap supplied, to prevent it from rotating.
  
  
• Manual override with magnet possible (the gear is disengaged as long as the magnet adheres to the symbol U. The magnet for gear disengagement is integrated in the position indicator.


• Adjustable angle of rotation with mechanical end stops.


• High functional reliability 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 and after every voltage interruption, the synchronisation process is started and the actuator travels to home position (Y = 0 V).
