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 the installation switch establishes the custom limit. An up/down switch may also be connected to the operator. Actuation of the up/down switch during setting of the operational profile and after setting of the custom lower limit sets a custom upper limit.
A door operator for setting at least one custom travel limit on movable barrier travel, comprising:
A door operator for setting at least one custom limit on movable barrier travel, comprising:
A method for setting at least one travel limit for a motorized movable barrier for an opening controlled by an operator, wherein the position of the movable barrier is monitored by a potentiometer, and wherein a disconnect system is interposed between the operator and the motor, the method comprising:
A method for setting at least one custom travel limit for a motorized movable barrier, which encloses an opening, controlled by an operator, wherein the position of the movable barrier is monitored by a potentiometer, wherein an up/down switch is connected to the operator to control operation of the motor, and wherein an installation switch is connected to the operator, the method comprising:
