Abstract
A control system is provided for a door positioning assembly having a door mounted on a track. The door is movable between an open position and a closed position. The door has a leading edge adjacent a door opening, an edge arranged to define a second opening, and a pass door pivotably coupled to the second opening. The control system includes a proximity detector for providing a door position signal in response to the position of the door on the track system, and a user input for providing user input signals including open inputs, stop inputs including signals provided by a stop button of a user-operated switch, and close inputs in response to user commands. The system also includes a plurality of sensors for providing stop input signals in response to the position of an object located within a detection zone adjacent the door opening, in response to contact between an object and the leading edge of the door, and in response to the position of the pass door. The system further includes a signal processor to provide controller instructions in response to the door position signal and the user input signals, and a controller configured to vary the speed and direction of travel of the door in response to the controller instructions.
