Abstract
A door operator and related method of setting custom limits on movable barrier travel, includes a motor for moving the movable barrier between two travel limit positions, an operator for controlling operation of the motor, and a disconnect system coupled between the motor and the operator. The disconnect system is switchable between a connected position and a disconnected position, wherein the motor can engage the operator only when the disconnect system is in the connected position. The operator is connected to a potentiometer for ascertaining movable barrier position, regardless of the position of the disconnect system, and provides position information to the operator. A travel limit is set by placing the disconnect system in the disconnected position and manually moving the door to a desired position whereupon the disconnect system is moved to the connected position so that the operator can detect a positional location to be designated as one of the travel limits. An installation switch may be connected to the operator, wherein the operator determines a custom lower limit or a custom upper limit from the desired position as detected by the potentiometer, wherein actuation of th…
