CAUTION: THE PROJECTOR MUST BE TURNED OFF BEFORE CONNECTING THE
TRIGGER WIRES TO THE PROJECTOR. FAILURE TO DO SO MAY DAMAGE THE
CONTROLLER.
Use 2-conductor 20-24 gauge wire to extend the low voltage connection
from the projector’s 5 or 12-volt screen trigger output to the length
required to reach the VPI. When extending the low voltage connection
from the projector’s screen trigger output polarity does not matter. The
red and black wires from the VPI are interchangeable.

IMPORTANT NOTE:
The wall switch is REQUIRED to make any limit switch adjustments,
EVEN if a third party control system is used. Therefore, it is advised to
wire the switch or provide a 3-conductor connection that is accessible.
3-conductor 20-24 gauge wire can be used in place of the supplied RJ-14
cable to connect the wall switch. Connect the BUS terminals on the wall
switch to the corresponding BUS terminals on the splitter board.

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 5/32" Allen wrench to make adjustments.
SETTING THE DOWN LIMIT POSITION
TO REDUCE SCREEN DROP:
Turn the white limit switch screw (Figure 3) 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 adjust for more drop than what was ordered. At least 1-1/2 wraps of fabric must remain on the roller. This
screen comes standard with 0" or 2" black at the top. See the specification data sheet for details.
