Abstract
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.
Claims13
A method for setting a force adjustment on a barrier operator, wherein the barrier operator initiates corrective action if a detected obstruction force is deemed excessive, the method comprising:
- pre-setting a force threshold value used by the barrier operator;
- initiating a programming mode;
- moving the barrier from one limit position to another limit position while in said programming mode;
- determining a recorded value during the moving step;
- adjusting said force threshold value until equal to said recorded value;
- associating a sensory feedback device with said threshold value;
- enabling said sensory feedback device while in said programming mode;
- and
- disabling said sensory feedback device when said threshold value is equal to or greater than said recorded value.
A barrier operator system that provides a force setting adjustment comprising:
- a moveable barrier;
- a motor coupled to said moveable barrier, said motor moving said barrier between limit positions;
- a sensor associated with one of said moveable barrier and said motor to determine a recorded value of barrier movement;
- and
- an adjustment mechanism that allows adjustment of a threshold value from a pre-set minimal value until at least equal said recorded value;
- a sensory feedback device associated with said adjustment mechanism so as to provide an indication as to when said threshold value is at least greater than or equal to said recorded value;
- a controller connected to said sensory feedback device and to said adjustment mechanism, wherein said controller controls said motor and the position of said moveable barrier, said controller receiving a new speed value from said sensor and generating said recorded value therefrom;
- and
- wherein said sensory feedback device is enabled when said controller is in a programming mode, and wherein said sensory feedback device is disabled in said programming mode when said threshold is equal to or greater than said recorded force value.
