Electronic unit for manual and time dependent control of electric roller shutters - has at least four operating elements for input of control commands and two power end stations for controlling motors in clockwise and anticlockwise directions

摘要

A pulse generator (1) controls a counter (2) with a selected pulse, which resets to zero after reaching the greatest possible reading. The reading is led to two comparators (6) and a control logic (3). Two timers (7) are respectively connected to the two power end stages (8). Desired switching times resulting by a simultaneous operating of two operating elements (5) are "learnt" by the control, and are automatically repeated by the control. USE/ADVANTAGE - Electrically operated roller shutters, blinds and similar. This method of control replaces expensive programming of actual time, switching times and weekdays.
