Screen travel is stopped automatically in the down and up positions by the limit switches that are preset at the factory. If it's necessary
to adjust for more or less drop follow the steps below. The case cover must be removed to access the motor limit switches.
Remove the front cover of the screen from the back of the screen. Lift front cover up approximately 1/2" and pull away from back of
screen. See Figure 1.
Setting The Down Limit Position
To Reduce Screen Drop:
Turn the white limit switch screw clockwise to decrease the
amount of screen drop. Run the screen down to test the stop
position. If the screen drops too far, raise the screen about
one foot and adjust the limit switch again. Repeat until the
desired position is set.
To Increase Screen Drop:
Turn the white limit switch screw counterclockwise to
increase the amount of screen drop. Run the screen down to
test the stop position. If the screen does not drop enough,
raise the screen about one foot and adjust the limit switch
again. Repeat until the desired position is set. Do not adjust
for more drop than what was ordered. At least 1-1/2 wraps of
fabric must remain on the roller.
