220V Access by Draper

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.

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.

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.

Retaining

clip

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.
