Patent ID: 7075256

Claim:
A method for adjusting an internal force threshold setting for a motorized garage door operator actuated in response to a door move command, the method comprising: establishing a base line force application value applied by a motor to move a door between limit positions; storing in a controller maintained by the garage door operator said base line force application value; periodically checking for connection of any one of a plurality of entrapment safety features to said controller by said controller, said controller setting a force threshold to a default value if none of said entrapment safety features are connected to said controller and increasing said force threshold value a predetermined amount above said default value if at least one of said entrapment safety features are connected to said controller, wherein said periodic checking step is performed regardless of whether the door move command has been received or not; determining by the controller the amount of force applied by the motor during movement of the door; and implementing corrective action by said controller if the amount of force actually applied by the motor is greater or less than said base line force application value and said force threshold value.
