ABSTRACT:
An operator and related method for adjusting an internal force setting for a motorized garage door operator is disclosed. The operator checks for the presence of a secondary entrapment safety feature and automatically increases a force threshold setting from a first value to a second value if the secondary entrapment safety feature is detected. If the safety feature is not detected or it is later disconnected, then the operator automatically sets the force threshold to a more sensitive value.
