Abstract
An exemplary method involves operating a door operator coupled to a door. The door operator includes a motor operable to move the door in at least one direction and a controller operable to control the motor. The method generally involves a calibration procedure including: with the door at a first position and the door having an initial speed, initiating, by the controller, measurement of a time duration; in response to the door reaching a target speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and determining, by the controller, a maximum speed based on the time duration. The method further includes performing at least one operation based upon the maximum speed.
Claims22
A method of operating a door operator coupled to a door, wherein the door operator comprises a motor operable to move the door in at least one direction and a controller operable to control the motor, the method comprising:
- performing a calibration procedure, the calibration procedure comprising:
- with the door at a first position and the door having an initial speed of zero, initiating, by the controller, measurement of a time duration;
- in response to the door reaching a threshold speed different from the initial speed, ceasing, by the controller, measurement of the time duration;
- and
- determining, by the controller, a maximum speed based upon the time duration, wherein the maximum speed is a maximum allowable speed for the door;
- and
- subsequent to the calibration procedure, performing at least one operation based upon the maximum speed.
A method of operating a door operator coupled to a door, wherein the door operator comprises a motor operable to move the door in at least one direction and a controller operable to control the motor, the method comprising:
- performing a calibration procedure, the calibration procedure comprising:
- with the door at a first position and the door having an initial speed of zero, initiating, by the controller, measurement of a time duration;
- in response to the door reaching a threshold speed greater than the initial speed, ceasing, by the controller, measurement of the time duration;
- and
- determining, by the controller, a maximum allowable speed for the door based upon the time duration and a difference between the threshold speed and the initial speed;
- and
- subsequent to the calibration procedure, performing at least one of a first operation or a second operation;
- wherein the first operation comprises providing a warning in response to a user-selected door speed exceeding the maximum allowable speed for the door;
- and
- wherein the second operation comprises limiting a speed of the door to the maximum allowable speed for the door.
