  • Bi-directional pass-point system for controlling the operation of movable barriers
    Patent number: 6400112
    Abstract: An operator for opening and closing movable barriers such as garage doors comprising a pass-point limit system which is a component of an operating head. An operator for a rolling shutter or gate can be installed on either side of the opening. A dual pass-point system provides a unique pass-point regardless of direction of mounting the operator, regardless of the direction of travel for opening the barrier, and regardless of installation configuration, eliminating the need for the installer to know which direction the motor is rotating or the barrier is travelling.

An operator for a rolling shutter or gate can be installed on either side of the opening. A dual pass-point system provides a unique pass-point regardless of direction of mounting the operator, regardless of the direction of travel for opening the barrier, and regardless of installation configuration, eliminating the need for the installer to know which direction the motor is rotating or the barrier is travelling. The operator automatically learns both the open and close limits, regardless of direction of travel and without having to press a learn switch to set the open and close limits.
