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. 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 Converter for sensors Parameterisable actuators Simple direct mounting High operational reliability Home position Conventional operation: 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. Operation on the -Bus: he actuator receives its digital positioning signal from the higher level controller via the -Bus and travels to the position defined. Connection serves as communication interface and does not supply an analogue measuring voltage. Connection option for a sensor (passive or active sensor or switching contact). he actuator serves as an analogue/digital converter for the transmission of the sensor signal via -Bus to the higher level system. he factory settings cover the most common applications. Input and output signals and other parameters can be altered with the BELIMO Service tool MF-P or the adjustment and diagnostic tool ZH-GEN Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating. 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, the actuator automatically detects its emergency position (zero initialisation). his process, which takes place with the actuator stationary, lasts <15 s.
