SCREEN ADJUSTMENT FOR 220/240V SCREENS WITHOUT A BUILT-IN LOW VOLTAGE CONTROL
Surface travel is stopped automatically in the fully opened and closed positions by limit switches that are properly
adjusted at DA-LITE. Should it be necessary to adjust for more or less picture drop (viewing area), proceed in the
following manner:
NOTE: Use a screwdriver or allen wrench to make adjustments.
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.
