LMA-MF-P Multifunctional damper actuator, AC/DC V, Nm echnical data (continued) Dimensions / Weight Dimensions See «Dimensions» on page Weight Approx. g Safety notes 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. he cable must not be removed from the device. 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. Product features Mode of operation Parameterisable actuators Simple direct mounting Manual override Adjustable angle of rotation High functional reliability Home position he actuator is controlled with a standard modulating signal of DC... V and moves to the position defined by the control signal. he measuring voltage serves for the electrical display of the damper position... % and as slave control signal for other actuators. he factory settings cover the most common applications. Input and output signals and other parameters can be altered with the MF-H parameterising device or the BELIMO Service ool, MF-P. 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 with mechanical end stops. he actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached. When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the «gear disengagement» switch, the actuator moves to the home position. Pos. Direction of rotation switch Home position = ccw Left stop = cw Right stop he actuator then moves into the position defined by the control signal.
