GM4A-SR-P Modulating damper actuator, AC/DC 4 V, 40 Nm Safety notes Product features! Mode of operation Simple direct mounting Manual override his actuator is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport. It may only be installed by suitably trained personnel. Any legal regulations or regulations issued by authorities must be observed during assembly. he device may only be opened at the manufacturer s site. It does not contain any parts that can be replaced or repaired by the user. When calculating the required torque, the specifications supplied by the damper manufacturers (cross section, design, installation site), and the air flow conditions must be observed. he 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. he actuator is controlled with a standard modulating signal of DC 0... 0 V and moves to the position defined by the control signal. he measuring voltage U serves for the electrical display of the damper position 0... 00% and as slave control signal for other actuators. 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 with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). Adjustable angle of rotation High functional reliability Adjustable angle of rotation with mechanical end stops. he actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
