220V & 12V VIDEO INTERFACE CONTROL
—(Not CE Approved) Allows
screen to be con trolled by a trigger signal—when the signal comes on, the
screen de scends automatically. Two versions: Model VIC220 in te grates 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), per mit ting in de pen dent
operation. VIC–OS not avail able with factory installed VIC220 & VIC12.
KEY OPERATED SWITCHING
—(Not CE Approved) Two kinds of key-
op er at ed switch es are optionally available with this unit.
➀
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.
➁
A three-position key switch permits the screen to be op er at ed directly by
key. In this case, the screen’s operator must always have a key.
RS232/ETHERNET—
Serial communication and network communication
optionally available with wall switches, RF or IR remote.

Motorized Roller/Fabric Installation
The bottom access panel must be removed fi rst.
The motor end mounting bracket has a metal bracket with snap ring for
accepting motor head. Back out the four set screws in bracket until they are
fl ush with top side of bracket.
To engage the motor end bracket fl ange
above the two channels in the top of
the screen housing, rotate the bracket
approximately 45° coun ter clock wise to
allow the top surface of the motor bracket
to rest fl at against the top inside of the
housing. Rotating the bracket clockwise
until it is engaged with the chan nels, slide
it along the length of the housing against
the electrical junction box.
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,
and centered in case.
Locate the black washer and retaining clip
attached to the instruction sheet.
Note: This step requires two people
to perform safely.
Raise the roller/fabric
assembly up into the screen housing and
en gage the head of the motor completely
into the motor mount ing bracket, making
sure the snap ring engages with the motor
and that the limit switch ad just ing knobs
are visible from the bottom of the screen
housing.
While supporting the idler end of the
roller, slide the idler end mount ing bracket
toward the roller. In sert the roller pin
into the nylon bush ing on the idler end
mount ing brack et.
The roller idler pin needs to go through
the idler brack et far enough to al low the
washer and re tain ing clip to be re in stalled
on the pin.
Failure to replace the wash er and
re tain ing clip could re sult in the sep a ra tion
of the roller from the brackets.
The roller/fabric assembly and roller brackets may need to be slid left or right
in the mounting channel of case to center fabric within screen case.
Securely tighten the set screws on roller mount ing brackets.
Con nect the elec tri cal plug from the mo tor to the mat ing sock et on the
junc tion box.
Re in stall the bot tom access panel as pre vi ous ly de scribed.
Motorized Roll er/Fab ric Re mov al
Reverse the in struc tions above “Motorized Roll er/Fabric Installation” for
re mov al of the unit.
Operation
When screen is fi rst op er at ed,
be cau tious!
Cy cle unit down and up sev er al
times to con fi rm sat is fac to ry operation.
220V SINGLE STATION CON TROL—
3-position UP-OFF-DOWN switch
permits operation to be stopped at any point. Fac to ry ad just ed limit switches
au to mat i cal ly stop screen when fully down or fully up.
220V MULTIPLE STATION CONTROL
—(Not CE Approved) Switches are
similar in ap pear ance to 220V Single Station Control. Screen stops when
switch is re leased and may be re start ed in either direction. Factory adjusted
limit switches stop screen au to mat i cal ly when fully up or fully down.
24V CONTROL
—Three-button UP-STOP-DOWN switches stop at any
point desired, operate in any se quence. Factory adjusted limit switches
automatically stop screen when fully up or fully down. Installer should
incorporate an all-pole disconnect in the fi xed wiring.
Adjustments
Screen has been factory set and should not nor mal ly require further
ad just ment. However, if you desire to change the “up” and “down” stopping
po si tions, refer to drawing below and determine whether you need to adjust
the white socket or the yellow socket, and proceed as fol lows:
CAUTION:
Be sure all switches are in “off” position before adjusting limit
switches. Always be pre pared to shut screen off man u al ly when new
ad just ment is being tested. Screen may be se vere ly damaged if viewing
surface is al lowed to run too far up or too far down.
ADJUSTING WHITE SOCKET
—White socket is located on the motor end
of screen roller and is accessible to a small fl at screwdriver. Turning the
socket counterclockwise will allow the roller to run farther up or down (as
appropriate). Turning it clockwise will shorten op er a tion, caus ing it to stop
sooner. One full revolution of the socket will alter the stopping position of the
viewing surface by ap prox i mate ly 32 mm.
ADJUSTING YELLOW SOCKET—
Yellow socket is located on the motor
end of screen roller and is accessible to a small fl at screwdriver. Turning the
socket counterclockwise will allow the roller to run farther up or down (as
appropriate). Turn ing it clockwise will cause the roller to stop sooner. One full
revolution of the socket will alter the stopping position of the viewing surface
by ap prox i mate ly 32 mm.
AT NO TIME SHOULD VIEWING SURFACE BE UNROLLED ENOUGH TO
EX POSE ANY PART OF SCREEN ROLLER.

Tab-Tension Adjustment Procedure for Access/Series V
Draper’s Tab-Tensioning System is factory-
set, and under normal circumstances will
not require fi eld adjustment. If, however,
you notice wrinkles, waves, or other
indications that the tensioning cables need
to be adjusted, follow the procedure below.
➀
Determine which side requires
adjustment.
➁
Secure dowel with one hand.
Caution: Do not touch or bend surface.
➂
Using Philips-head screwdriver, depress
spring-loaded adjustment screw (see diagram at right) and slowly turn
clockwise to tighten tension, or counterclockwise to loosen tension. The
screw adjusts in ¼ turn increments. Adjust only
one increment
(¼ turn) at
a
time.
➃
If problem is not corrected, leave screen in position for 24 hours to allow
surface material to stretch into position.
➄
If problem still is not corrected, repeat steps 2 and 3.
