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.
