Safety Obstruction Force Adjustment – Open Direction 



Hinge open the Lamp Cover (Fig.18-A) to expose the adjustment controls. 



With the garage door in the 

fully

closed

 position - press the black “Run” Button (Fig.18-G) so that the 

garage door begins movement in the open direction. 



As the garage door is opening slowly turn the (green) Open / Offset Adjustment Pin (Fig.18-G) in an anti-
clockwise direction until the garage door stops. 



Now turn the same pin clockwise 5 degrees. 

Testing Safety Obstruction Force – Open Direction 



With the garage door in the 

fully closed

 position - stand inside the garage just behind the path of the garage 

door close to its middle position. 



Press the black “Run” Button (Fig.18-G) so that the garage door begins to open. 



When the garage door has opened by approx 450mm apply some firm downward force to one of its 
structural members. 



If the Safety Obstruction Force Adjustment is correct the AGDO will stop the garage door upon sensing the 
applied force. 



If too little or too much force is required to make the AGDO stop - rotate the (green) Open / Offset 
Adjustment Pin 5 degrees in the appropriate direction (clockwise to increase force, anti-clockwise to 
decrease force) and then repeat the previous testing steps.  

Safety Obstruction Force Adjustment – Close Direction 



With the garage door in the 

fully open

 position, press the black “Run” Button (Fig.18-F) so that the garage 

door begins to close. 



As the garage door is closing - slowly turn the (red) Close / Speed Adjustment Pin (Fig.18-F) in an anti-
clockwise direction until the garage door stops and begins to Safety Reverse. 



Now turn the same pin clockwise 5 degrees. 

Testing Safety Obstruction Force – Close Direction 



 With the garage door in the 

fully open

 position stand inside the garage just behind the path of the garage 

door close to its middle position. 



Ensure that the Close Limit Travel Adjustment (Sec.11) has been set so that bottom of the garage door is 
resting firmly against the ground. 



Press the black “Run” Button so that the garage door begins to close. 



Place a 32mm thick block of wood under the line of the garage door (approx at the mid point of the garage 
door) so that the garage door will close onto the block of wood. 



If the Safety Obstruction Force Adjustment is correct the AGDO will stop and reverse the direction of the 
garage door upon sensing the block of wood. 



If the AGDO stops but does not reverse then turn the (red) Close / Speed Adjustment Pin 5 degrees in an 
anti-clockwise direction. (Fig.18-F)
