It may only be installed by suitably trained personnel. Any legal regulations or regulations issued by government agency authorities must be observed during assembly. he device does not contain any parts that can be replaced or repaired by the user. 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 he actuator is controlled with a standard modulating signal and travels to the position defined by the control signal. he measuring voltage U serves for the electrical display of the actuator position % and as slave control signal for other actuators. Parameterisable actuators Simple direct mounting Manual override Internal heating Input and output signals and other parameters can be altered with the BELIMO Service ool, MF-P. Simple direct mounting on the butterfly valve. he mounting position in relation to the butterfly valve can be selected in 90 steps. he butterfly valve can be closed (turn clockwise) and opened (turn counterclockwise) with the handwheel. he handwheel does not move while the motor is running. An internal heater prevents condensation buildup. High functional reliability Mechanical stops limit the actuator to and 9. he internal limit switches interrupt the voltage supply to the motor. In addition, a motor thermostat provides overload protection because at 35 C it interrupts the voltage supply. Combination butterfly valve actuators For suitable butterfly valves, their permitted media temperatures and closing pressures are refered to the butterfly valve documentation.
