The blind actuator receives and controls roller shutters and blind drives with 230V motors with integrated limit switches. Two safety functions are also possible in this blind actuator (e.g. safety position in wind and/or rain, lock-out protection - if the patio door is open, this roller shutter/blind must not close). Note: Several shading motors must not be connected in parallel to a blind actuator without an isolating relay. The power is supplied via the mains. The device is installed in the switch or junction box. When using with inductive loads (e.g. fluorescent lamps), it is essential to pay attention to the protective circuit!
