The blind actuator receives telegrams from sensors via the Instabus and controls a shutter or blind motor with its output. Both travel directions are mechanically interlocked. With sun protection or positioning telegrams, the actuator offers moreover the possibility of moving shutters, blinds and slats into any desired position. On reception of a storm warning, the actuator is capable of moving shutters or blinds into a predefined safety position and to lock them up in this position.
In addition, the device has two extension inputs that depending on parameter settings, can act directly on the output (local operation, see “state of delivery”) or alternatively also as binary inputs on the Instabus. The connected potential-free switch or push button contacts are read in via a common reference potential on the actuator. As binary input, telegrams can be transmitted for switching or dimming, for Venetian blind control, value setting or scene recall / save.
