Motorized Roller/Fabric Installation
The bottom access panel must be removed first. The Access/MultiView has
two roller/fabric assemblies. The one equipped with a complete projection
screen fabric is installed first, higher in the brackets, and connects to the
left-hand junction box. The second roller has black masking strips at the sides
and no fabric in the middle: it installs lower in the brackets and connects to the
right-hand junction box.
The motor end mounting brackets have steel mounting rings with prongs that
engage with motor head.
To engage the motor end bracket flange above the two channels in the top of
the screen housing, rotate the bracket approximately 45° counterclockwise
to allow the top surface of the motor bracket to rest flat against the top inside
of the housing. Rotating the bracket clockwise until it is engaged with the
channels, slide it along the length of the housing toward the electrical junction
box at left end of case.
Motor roller
assembly
Idler end roller
mounting bracket
Engage the idler end bracket (rectangular mounting pad) in the same manner
as the motor end bracket and slide it toward the opposite end of the screen
housing. Do not tighten the set screws on this bracket until the roller/fabric
assembly is installed.
Locate the viewing surface roller/fabric assembly and remove the retaining
clip and flat steel washer from the idler end pin.
(NOTE: This will require two people to perform safely.) Raise the viewing
surface roller/fabric assembly up into the screen housing and en-gage the
head of the motor completely into the motor mounting bracket. The steel clip
on the motor mounting ring must snap into the groove on the motor. Once this
is done the clip must be manually pulled down away from the mounting ring to
disengage motor. Make sure the limit switch adjustment knobs are visible from
bottom of housing.
While supporting the idler end of the roller, slide the idler end mounting
bracket toward the roller. Insert the roller pin into the nylon bushing on the
idler end mounting bracket.
The roller idler pin needs to go through the idler bracket far enough to allow
the steel washer and retaining clip to be reinstalled on the pin. Failure to
replace the washer and retaining clip as shown could result in the separation
of the roller from the brackets.
The fabric/roller assembly and brackets will need to be moved left or right
until centered in case. Tighten two set screws on each roller mounting bracket
using

Locate the masking roller assembly and remove the retaining clip from motor
stud and remove retaining clip and washer from idler pin.
Raise masking roller up into screen housing making sure motor is on the
right (as viewed by audience). Engage the motor stud inside square bushing.
Engage the idler pin all the way through the round bushing on left roller
mounting bracket. Place washer over pin and fasten retaining clip in the
groove of idler pin.

Motorized Roller/Fabric Removal
Reverse the instructions above under "Motorized Roller/Fabric Installation"
for removal of the unit.
Operation
When screen and masking are first operated, be cautious! Cycle unit down
and up several times to confirm satisfactory operation. Factory adjusted limit
switches should automatically stop screen or masking when fully down or
fully up. Separate controls operate screen and masking motors, unless the
Access/MultiView Control is used.
220V SINGLE STATION CONTROL (2 standard)—3-position UP-OFF-OWN
switches permit operation to be stopped at any point.
220V MULTIPLE STATION CONTROL—(Not CE Approved) Switches are
similar in appearance to 220V Single Station Control. Screen stops when
switch is released and may be restarted in either direction.
ACCESS/MULTIVIEW CONTROL—This 24V control permits both motors to
be operated from a single switch, which is equipped with two sets of UP-0FF-
DOWN buttons.
24V MULTIPLE STATION CONTROL—Separate three-button UP-STOP-
DOWN switches for each motor, stop at any point desired, operate in any
sequence.
220V & 12V VIDEO INTERfACE CONTROL—(Not CE Approved) Allows
screen to be controlled by a trigger signal—when the signal comes on, the
screen descends automatically. Two versions: Model VIC220 integrates screen
operation with a DRAPER video projector lift or a video projector or tuner with
a 220V switched outlet. Model VIC12 interfaces with a 12V switched outlet.
Both available with an override switch (VIC–OS), permitting independent
operation. VIC–OS not available with factory installed VIC220 & VIC12.
KEY OPERATED SWITCHING—(Not CE Approved) Two kinds of key-
operated switches are optionally available with this unit.
1 The key-operated power supply switch controls power to the screen and
switches. When it is "off", the switches will not operate screen.
Key may be removed from the switch in either "on" or "off" position.
2 A three-position key switch permits the screen to be operated directly by
key. In this case, the screen's operator must always have a key.
