2 SRA-MF Multifunctional rotary actuator AC/DC V, 0 Nm Safety notes Product features! Mode of operation he damper 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. All applicable legal or institutional installation regulations must be complied with. he switch for changing the direction of rotation may only be operated by authorized personnel. he direction of rotation must not be reversed in a frost protection circuit. 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 is not allowed to be removed from the unit. 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 V and travels to the position defined by the control signal. Measuring voltage serves for the electrical display of the actuator position % and as slave control signal for other actuators. Parameterisable actuators Simple direct mounting Manual override Adjustable angle of rotation High functional reliability Home position 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. Straightforward direct mounting on the ball valve with only one screw. he mounting position in relation to the ball valve can be selected in 90 steps. Manual operation with pushbutton possible - temporary, permanently. he gear is disengaged and the actuator decoupled for as long as the button is pressed / latched. 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 travels to the home position. Factory setting: Direction of rotation (counter-clockwise rotation) Rotary actuator Rotary valve A AB = 0% A AB = 00% he actuator then moves into the position defined by the control signal.
