1. A closure operating device for opening and closing an overhead closure, the closure operating device comprising:

  • a motor operatively connected to an output shaft for rotation thereof, said output shaft being adapted to drive said closure for displacement thereof along a travel path between open and closed limit positions;

    a sensing system operable to at least one of stop and open the closure upon detection of the presence of an obstacle obstructing the travel path of said closure;

    a control system in communication with said motor and said sensing system, said control system including a control unit operable to deactivate said sensing system at a selected point prior to said closed limit position of said closure;

    at least one switch in communication with said control system and actuable by a switch actuator, the switch actuator being displaceable along the output shaft and operable to actuate said switch when disposed in a predetermined position therealong; and

    wherein the control system determines one of said selected point for the deactivation of the sensing system and the closed limit position of the closure, based on a delay period relative to the actuation of said switch.
