SCREEN ADJUSTMENT FOR 220/240V SCREENS
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 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.
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.

!
CAUTION: Do not allow the slat bar to wrap over the top of the roller when the screen is rolling into the case. The
screen could be damaged.
SCREEN TRAVELS INTO CASE TOO FAR:
Turn the red 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 red 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. Repeat until the desired position is set.
