    摘要: A method for controlling a motorized barrier operator after detecting an obstruction includes the steps of providing a motorized barrier operator that moves a barrier between limit positions and providing at least one control switch that upon actuation moves the barrier in a direction toward one of the limit positions. Actuation of the at least one control switch during movement of the barriers at least causes the barrier to stop. If an obstruction is detected by the motorized barrier operator during movement of the barrier, the operator allows only uni-directional movement of the barrier, regardless of actuation of the at least one control switch, after the detecting step.

    摘要: A method and system for setting a downward force adjustment exerted by a barrier is disclosed. As is known, the barrier operator initiates corrective action if a detected obstruction force is deemed excessive. The inventive method and system comprises pre-setting a force threshold value used by the barrier operator. While in a programming mode, the barrier is moved from one limit position to another limit position. A recorded value is determined during the moving of the barrier and the threshold value is adjusted until equal the recorded value. A feedback device such as a light or a speaker is used to indicate when the threshold value is at least equal the recorded value.

    摘要: A movable barrier operator system includes a motorized operator which moves a barrier between limit positions, and a photo-electric safety system connected to the motorized operator. The photo-electric safety system monitors for obstructions at more than one height along the barrier's path between limit positions. This is done by installing a supplemental photo-electric safety system to work in conjunction with a pre-existing photo-electric safety system connected to the motorized barrier operator.
