Abstract
A door is coupled to a door operator that includes a motor operable in a predefined power assist mode to open the door from the closed position toward the open position. The assistance provided by the motor is reduced relative to the assistance in the power assist mode in response to the door opening angle being more than a threshold amount, and further in response to a speed of the door exceeding a threshold amount as the door is being opened.
Claims20
A method for opening a door coupled to a door operator assembly having a motor, the method comprising:
- operating the motor in a predefined power assist mode to open the door from a closed position toward a fully open position, wherein the door pivots during opening so that an angle of the door increases from the closed position toward the fully open position;
- during operating the motor, determining:
- a speed of the door exceeds a threshold speed;
- or
- the angle of the door exceeds a threshold angle;
- and
- in response to the determining, adjusting the motor from the predefined power assist mode to reduce assistance from the motor to the door during opening the door.

A system for opening a door mounted to a frame, the system comprising:
- a door operator connectable between the door and the frame, wherein the door pivots during opening so that an angle of the door increases from a closed position toward a fully open position;
- a motor operable to drive the door operator to move the door from the closed position to the open position;
- and
- a controller connected to the motor, wherein the controller is configured to:
- operate the motor in a predefined power assist mode to open the door from the closed position toward the fully open position;
- determine that a speed of the door exceeds a threshold speed and/or the angle of the door exceeds a threshold angle;
- and
- reduce assistance from the motor to the door relative to assistance provided in the predefined power assist mode during opening the door in response to the speed of the door exceeding the threshold speed and/or the angle of the door exceeding a threshold angle.
