Features

• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the position defined by the control signal. 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 The actuator can be directly connected with the application using the enclosed screws. The head of the gear rod is connected to the moving part of the ventilation application individually on the mounting side or with the Z-KS2 coupling piece provided.

• Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).

• Stroke adjustment  The stroke of the gear rack can be adjusted on both sides in increments of 20 mm by means of mechanical end stops.

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


• Home position The first time the supply voltage is switched on, i.e. during initial startup, the actuator carries out an adaptation. After pressing the «gear disengagement» pushbutton, the actuator moves to the home position at the end stop.The actuator then moves into the position defined by the control signal
