Abstract
A sectional door operator system (I) opens and closes an opening (2) by operating a plurality of horizontal and interconnected sections (9a-e) that form a sectional door. A door frame (3) is formed by first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2). The plurality of horizontal and interconnected sections (9a-e) are connected to the door frame (3) to move between an open and a closed position. A drive unit (IO) is mounted on a section (9e) of the door. The drive unit (IO) is arranged to move the sectional door (8) from the closed position (C) to the open position (0). The drive unit (IO) includes a first motor (I la) and a second motor (I lb, which are mounted at different vertical sides of the horizontal and interconnected section (9e). A control unit (20) controls the operation of the drive unit (IO). A first sensing element (30a) and a second sensing element (30b) provide operational data of the first and second motor (1 la, 1 lb) to the control unit (20).
