Safety notes! he actuator is not allowed to be used outside the specified field of application, especially not in aircraft or any other form of air transport. Assembly must be carried out by 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 nut be removed from the device. he rotary supports and coupling pieces available as accessories must always be used if lateral forces are likely. In addition, the actuator must not be tightly bolted to the application. It must remain movable via the rotary support (refer to «Assembly notes»). If the linear actuator is exposed to severely contaminated atmosphere, appropriate precautions must be taken on the system side. Excessive deposits of dust, soot etc. can prevent the gear rack from being extended and retracted correctly. If not installed horizontally, the gear disengagement pushbutton may only be actuated when there is no pressure on the gear rod When calculating the required actuating force, the specifications supplied by the damper or slide valve manufacturers (cross section, design, installation site), and the air flow conditions must be observed. If a rotary support and/or coupling piece is used, losses in the actuation force are to be expected. 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 Stroke adjustment High functional reliability 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 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. he actuator can be directly connected with the application using the enclosed screws. he head of the gear rod is connected to the moving part of the ventilation application individually on the mounting side or with the Z-KS coupling piece provided. Manual operation is possible with the pushbutton (the gearing latch remains disengaged as long as the pushbutton is pressed or detented). he stroke of the gear rack can be adjusted on both sides in increments of mm by means of mechanical end stops. he actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached. / 6 -LHA-MF.. en v. 8.9 Subject to changes

3 LHA-MF.. Multifunctional linear actuators, AC/DC V, N Product features Accessories Home position (Continued) 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. Pos. direction of stroke switch = = Home position extended retracted he actuator then moves into the position defined by the control signal.

Control signal Measuring voltage Cable colours: = black = red = white = orange Assembly notes Application without lateral forces Application with lateral forces Caution If a rotary support and/or coupling piece is used, losses in the actuation force are to be expected.! he linear actuator is screwed directly to the housing at three points. Afterwards, the head of the gear rod is fastened to the moving part of the ventilation application (e.g. damper or slide valve). he coupling piece with the internal thread (Z-KS) is connected to the head of the gear rod. he rotary support (Z-DS) is screwed to the ventilation application. Afterwards, the linear actuator is screwed to the previously mounted rotary support with the enclosed screw. Afterwards, the coupling piece, which is mounted to the head of the gear rod, is attached to the moving part of the ventilation application (e.g. damper or slide valve). he transverse forces can be compensated for to a certain limit with the rotary support and/or coupling piece. he maximum permissible swivel angle of the rotary support and coupling piece is, laterally and upwards. -LHA-MF.. en v. 8.9 Subject to changes / 6
