Mode of operation Converter for sensors Simple direct mounting he actuator is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport. hey 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. he actuator is equipped with an integrated interface for WORKS. he actuator can be connected and controlled directly with WORKS via transceiver F-0A. Connection option for a sensor (passive or active sensor or switching contact). In this way, the analogue sensor signal can be easily digitised and transferred to WORKS. Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating. High operational reliability Home position 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 <5 s.
