SCREEN ADJUSTMENT
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. Adjustment procedures are different for 120V and 240V
units. Follow the appropriate instructions for your screen type.
The case cover must be removed to access the motor limit
switches.
Remove the case cover screw from both ends of the screen.
See figure 4. Be sure to hold the cover while removing the
screws.
Rotate the cover up and away from the case until it can be
removed.
INSTRUCTIONS FOR 120 VOLT SCREENS
SETTING THE DOWN LIMIT POSITION
TO REDUCE SCREEN DROP:
Turn the number 1 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 number 1 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.

CAUTION: Do not allow the slat bar to become wedged between the roller and case. This could damage the fabric and motor.
Always check that the slat is free to move inside the case.
SCREEN TRAVELS INTO CASE TOO FAR:
Turn the number 2 limit switch screw clockwise to decrease the amount of travel. Run the screen up to test the
stop position. If the screen does not stop properly, lower the screen about one foot and turn the limit switch again.
Repeat until the desired position is set.
SCREEN DOES NOT TRAVEL FAR ENOUGH INTO CASE:
Turn the number 2 limit switch screw counterclockwise to increase the amount of up travel. Run the screen up to
test the stop position. If more travel is desired, lower the screen about one foot and adjust the limit switch again.
