STEP 1: Testing the Limit Settings: To check the Limit Settings, start
the Opener by pushing the standard wall Push Button or Super Station. Be
prepared to activate the button again quickly - per the Operating
Parameters outlined above - or if you see that the door is going to over
travel. As illustrated above, move the Cams toward the Power Unit to
DECREASE door travel and toward the Front Idler to INCREASE door
travel. Adjust the Up Limit Cam so that the door comes to rest where it
normally would without an electric Opener. Adjust the Down Limit Cam
so that the door closes firmly without putting undue stress on the Door
Arm. At full closed position, the door arm assembly should compress
approximately one inch.
STEP 2: Adjusting the Sensitivity Force —
Sensitivity System force adjustment screws are located
on the side rails of the Power Unit and can easily be
adjusted with a screwdriver. Turn the screws
CLOCKWISE for more force and
COUNTERCLOCKWISE for less force.
STEP 3:
Testing the Sensitivity Force — To test the
Sensitivity System, start the Opener and grasp the
bottom door handle halfway through the door's travel
(opening or closing). When testing in the CLOSE
direction, a second person will be needed to maintain
pressure on the Push Button IF an Auxiliary Entrapment
Protection Device has not yet been fitted. If a second
person is
unavailable, use a
stiff cardboard
carton placed in the
door's downward
path to indicate the
force the Opener is
exerting. If the force adjustment screws are properly set,
the door should stop if opening, and reverse if closing
without exerting undue pressure.
STEP 4: Testing the Opener’s Reversing System —
To test the Opener's Reversing Feature at floor level,
place a solid object at least 1-1/2" thick (such as a
standard 2 X 4 board laid flat) on the ground where the
center of the door will contact it. Close the door. If the
