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

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 ﬂ at 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 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 engage the head of the motor completely into the motor mounting bracket, making sure the snap ring engages with the motor and that the limit switch adjusting knobs are visible from the bottom of the screen 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 washer and retaining clip to be reinstalled on the pin.

Failure to replace the washer and

retaining clip could result in the separation of the roller from the brackets.

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.

➀The 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.

➁A 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.

RS232/ETHERNET—Serial communication and network communication optionally available with wall switches, RF or IR remote.

Adjustments

Screen has been factory set and should not normally require further adjustment. However, if you desire to change the “up” and “down” stopping positions, refer to drawing below and determine whether you need to adjust the white socket or the yellow socket, and proceed as follows:

CAUTION: Be sure all switches are in “off” position before adjusting limit switches. Always be prepared to shut screen off manually when new adjustment is being tested. Screen may be severely damaged if viewing surface is allowed 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 ﬂat screwdriver. Turning the socket counterclockwise will allow the roller to run farther up or down (as appropriate). Turning it clockwise will shorten operation, causing it to stop sooner. One full revolution of the socket will alter the stopping position of the viewing surface by approximately 32 mm.

ADJUSTING YELLOW SOCKET—Yellow socket is located on the motor end of screen roller and is accessible to a small ﬂat screwdriver. Turning the socket counterclockwise will allow the roller to run farther up or down (as appropriate). Turning it clockwise will cause the roller to stop sooner. One full

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 mounting brackets.

Connect the electrical plug from the motor to the mating socket on the junction box.

Reinstall the bottom access panel as previously described.

Motorized Roller/Fabric Removal

Reverse the instructions above “Motorized Roller/Fabric Installation” for removal of the unit.

Operation

When screen is ﬁ rst operated, be cautious! Cycle unit down and up several times to conﬁ rm satisfactory operation.

220V SINGLE STATION CONTROL—3-position UP-OFF-DOWN switch permits operation to be stopped at any point. Factory adjusted limit switches automatically stop screen when fully down or fully up.

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. Factory adjusted limit switches stop screen automatically when fully up or fully down.

24V CONTROL—Three-button UP-STOP-DOWN switches stop at any point desired, operate in any sequence. 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.

revolution of the socket will alter the stopping position of the viewing surface by approximately 32 mm.

AT NO TIME SHOULD VIEWING SURFACE BE UNROLLED ENOUGH TO EXPOSE 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 ﬁeld adjustment. If, however,
you notice wrinkles, waves, or other		Tensioning
indications that the tensioning cables need		Cable
to be adjusted, follow the procedure below.
➀ Determine which side requires	Dowel	Adjustment
adjustment.		Screw
➁ Secure dowel with one hand.

Caution: Do not touch or bend surface.

➂Using 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.

➃If problem is not corrected, leave screen in position for 24 hours to allow surface material to stretch into position.

➄If problem still is not corrected, repeat steps 2 and 3.
