4. Settings and adjustments
4.1 Door travel adjustment
The Drive Rail mounted Limit Prongs provide a one to one ratio between Limit
Prong movement and garage door movement thereby ensuring 100% accuracy
and ease of adjustment. Garage door fully open and fully closed positions can be
easily adjusted by moving the Limit Prong to the desired location in order to
increase or decrease garage door travel
Door travel adjustment – Close direction
Locate the Close Direction Limit Prong within the Drive Rail - nearest to front wall
of garage (Figure.13)
Loosen the Limit Prong Lock Screw by half a turn and slide the Limit Prong
towards the front wall of the garage to increase garage door travel and away from
the front wall to decrease garage door travel
Re-tighten the Limit Prong Lock Screw once correct adjustment has been attained
Note: The Limit Prongs work on a one to one ratio with the garage door, meaning
that if the Limit Prong is moved by 10 mm then the garage door will also move
by 10 mm
Door travel adjustment – Open direction
Locate the Open Direction Limit Prong within the Drive Rail – nearest to Control
Box. (Figure.13)
Loosen the Limit Prong Lock Screw by half a turn and slide the Prong towards the
Control Box to increase garage door travel and away from the Control Box to
decrease travel
Re-tighten the Limit Prong Lock Screw once correct adjustment has been attained
Note: The Limit Prongs work on a one to one ratio with the garage door -
meaning that if the Limit Prong is moved by 10 mm then the garage door
will also move by 10 mm.
