METHOD AND APPARATUS FOR AUTOMATICALLY ESTABLISHING CONTROL VALUES FOR A CONTROL DEVICE.

摘要

A movable barrier controller 41 has a force control 44 having a corresponding setting range. As operating conditions change, the barrier controller 41 can execute a learning mode 51. During this mode, the barrier controller 41 operates the barrier movement motor 42 and measures 53 at least one parameter that corresponds to operation of the motor 42. This measured parameter is used to determine 54 a control value which control value is then assigned 55 to a specific location within the setting range of the force control 44.
