Abstract
A sectional door operator system for opening and closing an opening comprises a door moved between open (O) and closed (C) positions and formed by horizontal and interconnected sections. The door is connected with a door frame with frame sections on opposite sides of the opening. A drive unit system is mounted on one of the sections that moves the sectional door from the closed position (C) to the open position (O). The drive unit system comprises first and second drive units, mounted on opposite sides of the section that each have a drive motor. A sensor device is mounted on a section and connected with a control unit. The control unit controls the drive unit system at least based on sensor data. The sensor data relates to an angle (φ) of the door in relation to a true horizontal plane of the sectional door operator system.
