Abstract
The disclosure relates to an overhead door operator system and to a method for controlling such a system. The overhead door operator system opens and closes an opening. The system includes a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) of the opening (2). A door (8) is movably connected to the door frame (3). A drive unit (10) is mounted on the door (8). An elongated transmission member (19) extends along the first side (7) of the opening (2) and the first frame section (4). The drive unit (10) includes a driven transmission member (18) in driving connection with the motor (11) and the elongated transmission member. The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages.
