Abstract
A method of powering an obstruction detector. Power is provided to an obstruction detector when a motor is executing a first movement and is suppressed to the obstruction detector when the motor is idle and when the motor is executing a second movement. The first movement moves a movable barrier towards a closed position, and the second movement moves the barrier towards an open position.
Claims7
A barrier movement operator comprising:
- a movable barrier;
- a motor connected to the movable barrier;
- an obstruction detector detecting obstructions along a predetermined path;
- a processor connected to the motor and the obstruction detector;
- and
- an operation control unit connected to the processor,
- wherein the processor is preprogrammed to grant power to the obstruction detector when the motor is executing a closing movement, and is preprogrammed to suppress all power to the obstruction detector when the motor is idle and when the motor is executing an opening movement.
