Abstract:
1. A barrier operator system, comprising a motor for moving a barrier between first and second travel limits, and a microcontroller, under software control, operative to: (a) establish the first and second travel limits; (b) direct the motor to move the barrier from the first travel limit to the second travel limit, and thereafter from the second travel limit to the first travel limit; (c) automatically record and store the respective forces required to move the barrier along discrete locations of barrier travel during movement of the barrier substantially an entire distance from the first travel limit to the second travel limit, and thereafter substantially the entire distance from the second travel limit to the first travel limit, thereby to define a force pattern of a continuous series of force values containing alternating maximum and minimum force values; (d) automatically generate a stepped configuration that tracks, and adds an increased offset to, each of the respective recorded maximum forces; thereby defining stepped configuration preliminary force sensitivity threshold profiles for substantially an entire distance from the first travel limit to the second travel limit of the barrier; and (f) respond to user-generated adjustments of each offset to define final force sensitivity threshold profiles.
