Movable barrier operator

Abstract

A movable barrier operator having an electrical motor responsive to control signals for moving the barrier, a controller to control the barrier movements, and two command apparatuses for generating command inputs, which command apparatuses are located remotely from each other. The first command apparatus is mounted in a location remote from the controller and easily accessible by the users, and the second command apparatus is located close proximity to the controller to be easily accessible by an installer at the time of service.

What is claimed is:  
     
         1 . A movable barrier operator, comprising: 
 a controller, responsive to command inputs for generating control signals to control barrier movement;    an electric motor responsive to control signals for moving the barrier;    a transmission connected to the motor to be driven thereby and to the movable barrier to be moved;    a first command apparatus mounted in a location remote from the controller and accessible by users of the movable barrier operator for manually generating command inputs; and    a second command apparatus comprising at least one command switch mounted in a location proximate to the controller and accessible by installers of the movable barrier operator for generating command inputs in response to installer interaction with the command switch.    
     
     
         2 . A movable barrier operator in accordance with  claim 1 , wherein the second command apparatus includes a plurality of switches.  
     
     
         3 . A movable barrier operator in accordance with  claim 2 , wherein the motor and the controller are mounted in a housing, and the second command apparatus is located at the housing.  
     
     
         4 . A movable barrier operator in accordance with  claim 3 , wherein the first command apparatus is mounted in a location remote from the housing.  
     
     
         5 . A movable barrier operator in accordance with  claim 1 , wherein the first command apparatus comprises a command switch.  
     
     
         6 . A movable barrier operator in accordance with  claim 1 , wherein the controller comprises a digital circuit for processing the functions of the operator, and a memory for storing instructions and data values pertaining to operation of the operator.  
     
     
         7 . A movable barrier operator in accordance with  claim 6 , wherein the controller comprises a receiver responsive to commands from a remote transmitter for operation of the barrier.  
     
     
         8 . A controller for a movable barrier operator, located at the operator, comprising: 
 a digital circuit for processing open, close, stop and other functions of the operator;    a memory storing instructions for operating the barrier operator and data values pertaining to operation of the operator; and    a plurality of logic controlled switches positioned at the barrier operator for enabling an installer to provide open, close, and stop functions and programming inputs to the digital circuit when providing service of the barrier operator.
