Screen Adjustment For Screens Without A Built-In Low Voltage Control
120V Wiring Diagram with Optional Built-In Video Projector Interface
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.
ATTENTION! N'effectuez pas de réglage pour obtenir un
déroulement supérieur à celui commandé. Au moins 1 à 1/2
tour de toile doit être maintenu sur le cylindre. Cet écran
est doté de série d'une bande noire supérieure de 0 cm (0
po) ou 5 cm (2 po). Consultez la fiche technique pour plus
de renseignements.
CAUTION: The projector must be
turned off before connecting the
trigger wires to the projector.
Failure to do so may damage the
controller.
ATTENTION: Le projecteur doit
être éteint avant de brancher les
fils de déclenchement à celui-ci.
Tout manquement à cette
instruction pourrait endommager
le contrôleur.
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.
