The S-line DuoFern tubular motor is a self-learning radio tubular motor with soft stop. For easy and quick integration into the Rademacher radio system, it features an integrated interface. Thanks to Plug & Play, it can be installed in a particularly time- and cost-saving manner, as the tubular motor does not require endpoint learning or a learning run. Only rigid shaft connectors or mounting springs, as well as stops or a stop bar, are necessary for self-learning. The motor automatically detects whether rigid shaft connectors or mounting springs have been used. It has precise position detection and torque monitoring, protecting the roller shutter with its integrated blockage detection and particularly sensitive obstacle detection. As soon as the roller shutter is blocked or encounters an obstacle, the motor reverses. Operation is carried out via radio transmitters, and in conjunction with, for example, the HomePilot®, it achieves extensive automation functions such as.
