Safety notes
The actuator is not allowed to be used outside the specified field of applicaion, especially t not in aircraft or any other form of air transport. Caution: Power supply voltage ! 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 manufacturers 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 specifications supplied by the damper manufactur ers (cross section, design, installation site), and the air flow 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.

Product features

Simple direct mounting Manual override Adjustable angle of rotation High functional reliability
Damper actuator, AC 100. 240 V, 5 Nm, Form-fit 8 mm
Simple direct mounting on the damper spindle by form-fit. The actuator, with its hollow shaft, is placed over the 8 mm square spindle of the damper and secured by two screws. 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 with mechanical end stops. The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.

LM230A Product features

Simple direct mounting Manual override Adjustable angle of rotation High functional reliability
Open-close damper actuator AC 230 V, 5 Nm
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 operation is possible with the self-resetting pushbutton (the gearing latch remains disengaged as long as the pushbutton is pressed). Adjustable angle of rotation with mechanical end stops. The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
