Limit Adjustments

Please Note: Screen limits are factory set for optimum performance of the

screen. A procedure is outlined below for minor tweaks, but any adjustment

of these limits may negatively affect the ﬂatness of the screen surface and

could also void the warranty. Please check with Draper prior to resetting

screen limits.

CAUTION: 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.

CAUTION: Be sure all switches are in “off” position before adjusting limit

switches.

The motor limit screws are normally located on the audience left of screen roller.

"Down" Limit Adjustment

To Reduce Screen Drop

1 Raise screen surface about 1' above desired setting and turn off.

2 Turn the WHITE/DOWN limit screw clockwise (3 screw turns=½ roller revolution).

3 Test by running screen down and repeat steps 1 and 2 until desired position is

reached.

To Increase Screen Drop

1 Run screen to the down limit.

2 With the down switch on, turn the WHITE/DOWN limit screw counterclockwise

(three turns of screw = ½ roller revolution) to increase drop.

3 Test by running screen up about 1' and back down to new down limit.

4 Repeat steps 2 and 3 until desired position is reached.

"Up" Limit Adjustment

Screen is Running Too Far Up

1 Lower screen surface about 1' below desired setting and turn off.

2 Turn the YELLOW/UP limit screw clockwise (3 screw turns = ½ roller revolution).

3 Test by running screen up.

4 Repeat steps 1 through 3 until desired position is reached.

Screen Needs to Run Up More

1 Run screen down about 1' and turn off.

2 With the up switch on, turn the YELLOW/UP limit screw counterclockwise (three

turns of screw = ½ roller revolution).

3 Repeat steps 1 and 2 until desired position is reached.

CAUTION: Do NOT allow the dowel to wrap up over the roller when the

screen is running up! This could damage the screen.

Installation/Operating Instructions

Signature/Series E & V Electric Projection Screen by Draper

Operation

Please Note: Screen limits are factory set for optimum performance of the screen.

Any adjustment of these limits could void the warranty. Please check with Draper

prior to resetting screen limits.

CAUTION—Important Instructions—Signature/Series V—The shipping support

bracket must be removed from the dowel during initial operation before screen is

operated in UP direction. After screen is installed, run viewing surface DOWN to access

and remove bracket. Signature/Series E—The protective paper wrapping around the

viewing surface must be removed before the screen is operated in down direction. Cycle

viewing surface down and up several times to conﬁrm satisfactory operation. If viewing

surface or trap door do not operate properly, turn power off and free trap door and/or

check electrical connections.

When screen is ﬁrst operated, be cautious! If automatic trap door does not open

immediately up into screen case when switch is ﬂipped “down”, return switch to “off” and

free trap door and/or recheck electrical connections before proceeding. Cycle unit down

and up several times to conﬁrm satisfactory operation.

110-120V 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.

110-120V Multiple Station Control—Switches are similar in appearance to 110-120V

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

down or fully up.

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 down or fully up. Wireless controls—whether infrared or radio frequency—

interface with the low voltage control box (see wiring diagram on reverse).

Key Operated Switching—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.

RS232/Ethernet—Serial communication and network communication optionally

available with wall switches, RF or IR remote.

Hanging Screen

When locating viewing surface and checking clearance for screen’s operation,

remember surface is centered in case. Screen is normally recessed above ceiling

and may be installed in a variety of ways. See typical installations detailed on back

of this sheet. Regardless of mounting method used, the following points apply:

1 Screen should be lifted into position only by the end mounting brackets.

Keep case level by lifting end plates simultaneously to prevent surface

damage. Never attempt to lift screen along its length.

2 Screen should be positively and securely supported so that vibration or even

abusive pulling on viewing surface will not weaken installation.

3 Installer must insure that fasteners used are of adequate strength and suitable

for the mounting surface chosen.

4 Entire bottom of case must be readily accessible after installation is complete.

5 Hinge that connects bottom panel and automatic trap door of screen must be

permitted to operate freely. Front and back of case must be straight—not forced

to warp or bow. Hinges must be free from mastic or paint buildup, and doors

must be unobstructed by ceiling tiles.

6 Do not use screen case to support adjacent sections of ceiling.

7 If trim pieces must be attached to case, do not permit screws to protrude more

than

" through

" wall of case. Do not attach trim pieces with nails.

8 If case is painted, slots on bottom of case should be shielded to protect viewing

surface from paint splatters or overspray.

9 Do not seal unit in ceiling until electrical connections have been made and

screen has been operated successfully.

Caution

1 Read instructions through completely before proceeding. Follow instructions

carefully. Installation contrary to instructions invalidates warranty.

2 Pick up screen case from ends only. Picking case up at other points will damage

case and may damage fabric.

3 To insure a safe installation, the entire weight of the unit MUST BE supported by

the end-plates.

4 Entire bottom of screen case should be unobstructed to permit proper operation of

automatic trap door, and access to bottom panel for making electrical connections

or servicing.

5 Screen should be installed level (using a carpenter’s level).

6 Nothing should be fastened to screen dowel or viewing surface.

7 Operating switch(es) is packed separately in screen carton. Do not discard with

packing material.

8 Screen operates on 110-120V, 60 Hz., 1.1 amp current draw for models using

small case; 1.3 for models using large case (see page 2).

NOTE: Screen has been thoroughly inspected and tested at factory and found to be

operating properly prior to shipment.

These instructions are meant as a guide only. They do not imply any responsibility on

the part of Draper, Inc. for improper installation or faulty workmanship at the jobsite.

Please Note: Instructions for adjusting Draper’s Tab-Tension System for Series V

screens are on page 2.

Electrical Connections

Screen operates on 110-120v, 60 Hz., 1.1 amp current draw for models using

Phillips screwdriver. Automatic trap door does not need to be opened to make ﬁeld

connections. Removal of access plate exposes red, black and white pigtail leads

and green internal ground wire per wiring diagram attached. Screen is shipped with

internal wiring complete and control switch(es) fully boxed. Wire connecting screen

to switch(es) and switch(es) to power supply should be furnished by installer.

Connections should be made in accordance with attached wiring diagram, and

wiring should comply with National and local electrical codes.
