SETTINGS AND ADJUSTMENTS 

11.

Door Travel Adjustment 



The Drive Rail mounted Limit Prongs provide a 1 to 1 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 (Fig.11) 



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. (Fig.11) 



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.

Safety Obstruction Force Adjustment 



Dual Safety Obstruction Force Adjustment modes ensure that the AGDO can be optimized to suit virtually 
any sectional or tip-up type garage door. 



ADAPTIVE MODE – constantly monitors incremental drive force value changes that occur due to seasonal 
conditions and / or garage door aging. Adaptive Mode compensates for these variables by automatically 
adjusting Safety Obstruction Force values during every complete cycle, resulting in enhanced safety and 
minimized chances of garage door *ghosting. (Refer Sec.12.1 for set up details)  
*Ghosting is defined as a Safety Stop or Safety Reverse without the garage door actually encountering an 
obstruction. 



MANUAL MODE – features conventional one time Safety Obstruction Force value adjustment and is more 
suited for use on badly worn or improperly balanced garage doors. (Refer Sec.12.2 for set up details)
