DATASHEET

STR-21 roller blind controllers are designed to control roller blinds (up and down) or other devices (for example, gates) which are driven by a single-phase AC electric motor and operated via momentary switches (for example, push buttons) . The regulator can operate as a standalone unit (designated to open / close a roller) as well as the controllers can be combined into groups allowing central control of many roller blinds.

OPERATION
The roller motor is activated by the momentary switching of a pulse current (L or N) to one of the control inputs. The motor is activated at a time previously programmed by the user. The programmed activation time allows you to fully raise or lower the roller. Furthermore, there is the possibility to stop the activated roller shutter at a level selected by the user (opening not completed or closing the roller).

Local control - a group of buttons that control a roller blind. upwards (opening); down (close). Pressing the local control button activates the movement of the roller in a selected direction. If the roller is already in motion, pressing the local control button stops the roller.

Central control - a common group of buttons for many controllers (minimum two controllers) that controls all the blinds included in the central control system. all upwards; all down. Pressing the central control button activates the movement of the roller blinds in a selected direction. If one of the blinds is already moving in the same direction, its movement will continue. If one of the roller blinds moves in the opposite direction, the latter will first be stopped and then its movement will be activated in the direction in accordance with the command sent to the central entrance.
