Closure operator control

A control circuit, comprising, in combination,

• an electric motor connectable to drive a load in first and second opposite directions toward first and second limit positions, respectively,
• electrical terminals connectable to an electrical power source,
• a power circuit connected to said motor and to said terminals for energization of said motor to drive said load in said first and second directions,
• a manual switch,
• first control means operable with the load at rest in said second position and interconnecting said switch and said power circuit and responsive to a first pattern of actuation of said switch to establish said motor operational to move the load in said first direction, and
• second control means operable with the load at rest in said first position and interconnecting said switch and said power circuit and responsive to a second pattern of actuation of said switch to establish said motor operational to move the load in said second direction.

A control system for a garage door operator motor connectable to open and close a garage door, comprising in combination,

• first contact means for energizing the motor from a voltage source for opening movement of the door,
• second contact means for energizing the motor from the voltage source for closing movement of the door,
• first control means to control the closing of said first contact means to effect opening movement of the door,
• second control means connected to control the closing of said second contact means to effect closing movement of the door,
• manual switch means connected to control said first and second control means, and
• logic means connected between said switch means and said second control means and responsive only to a plurality of closings of said switch means to activate the door operator for the closing movement.

A control system for connection to a closure of a building, comprising, in combination,

• output relay means,
• contact means on said output relay means and connectable to a voltage source,
• control means connected to control the actuation of said output relay means and corresponding to a given directional movement of the closure,
• switch means connected to actuate said control means,
• means for connecting one of said contact means and said switch means to the closure, and
• logic means connected between said switch means and said control means and responsive only to a plurality of closings of said switch means to activate said output relay means and the closing of said contact means.
