METHOD FOR OPERATING A BUILDING CLOSURE

摘要

A method for operating a building closure is disclosed. The building closure may be in the shape of a sectional door or a garage door. The position of the building closure and a motor current of a drive device is monitored by a control apparatus. When the building closure stands still, an electrical drive device arrests the building enclosure by providing an electrically conducting connection between winding of the drive device to ground. The position detection device continues to monitor a signal change such that in response to the signal change, the arresting is suspended and the electrical drive device is at least partially energized.

主权项

1. A method for operating a building closure having a motor engaged with the building closure movable between an open position and a closed position, the method comprising:
monitoring an instant position of the building closure; maintaining the building closure at the instant position; detecting a displacement of the building closure from the instant position; determining a direction of the displacement using a position detection device, the position detection device operable to signal a first displacement direction toward the open position and a second displacement direction toward the closed position; and in response to the detected displacement, instructing the motor to move the building closure in a direction opposite the signaled direction of displacement to return the building closure to the instant position.
