NOTE: The tube acts as a shock absorber during the opening
and closing of your garuge door. When the door is fully closed,
there will be some tube bowing. This bowing minimizes the
stress on the door and door hardware. See Fis. 48.
OPEN TRAVEL ADJUSTMENT
lSmall White Knobl
A. Activate power unit until the door opens and automatically
stops. Locate the small white open travel adjustment knob
on the bottom of the power unit. Slowly turn this knob in
the direction of the arrow (more open travel). The door will
"inch" its way open.
B. Continue to turn this knob until the desired open position is
selected. Do not force the door open any further than its nat-
ural open position. This may cause excessive strain on the
door or door opener. Trackless doors should be at a slight
downward angle when fully open. Reference Figure 19.
BEAM SENSOR TESTING
A. Push the hand-held transmitter to close the door. While the
door is closing, test the beam sensor by obstructing the
invisible beam. When obstructed, the red alignment light on
the receiving unit should turn off. The closing door should
stop, pause two seconds, then reverse and begin opening.
The lights on the door opener should flash.
B. Obstructing the beam while the door is opening will have
no effect.
