    • A control unit for a moveable barrier, such as a garage door, includes a microcontroller connected to a motor speed detector, motor current sensor or a sensor for determining forces exerted on or by the barrier. A user interface includes user actuatable switches for setting a first maximum force value to be exerted on or by the barrier when moving in one direction and the microcontroller automatically sets the value of a second maximum force to be exerted on or by the barrier when moving in the opposite direction. The second force value may be based on the force value set by the user or the second force value may be a preset value. Both force limits may be automatically set as a function of a maximum force exerted on said barrier during movement thereof, during a force learning operation.
    • 用于可移动屏障的控制单元,例如车库门,包括连接到电动机速度检测器,电机电流传感器或用于确定施加在屏障上或由屏障施加的力的传感器的微控制器。 用户界面包括用户可致动开关,用于在沿一个方向移动时设置施加在屏障上或通过屏障施加的第一最大力值,并且微控制器自动设置在移动时施加在屏障上或由屏障施加的第二最大力的值 相反的方向。 第二力值可以基于由用户设置的力值,或者第二力值可以是预设值。 在力学习操作期间,两个力极限可以被自动设定为在其移动期间施加在所述屏障上的最大力的函数。
