Hanging Screen

General:

When locating viewing surface and checking clearance for screen's opera-

tion, remember surface is centered in case. Screen is normally recessed

above ceiling and may be installed in a varie ty of ways. See typical installation

detailed on back of this sheet. Regardless of mounting method used, the fol-

lowing points apply:

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

Keep case level by lifting both ends 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 on bottom board and particularly hinge on 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 pro trude

through 19 mm (¾") wall of case. Do not attach trim with nails.

8 If case is painted, slots around doors 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.

Electrical Connections

Screen operates on 220V AC, 50 Hz., 1 ph. current.

Bottom board is held closed with flathead screws and may be opened with a

Phillips screwdriver/Allen wrench (4mm or

shut by viewing surface and must not be forced open. Junction box contains

Installation/Operating Instructions

Caution

"). Automatic trap door is held

Printed in U.S.A.

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.

All operating switches should be "off" before power is connected.

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

drop open immediately 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.

220V Single Station Control—3-position up-off-down switch permits opera-

tion 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 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. Installer should incorporate an all-pole

disconnect in the fixed wiring.

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.

RS232/Ethernet—Serial communication and network communication

optionally available with wall switches, RF or IR remote.

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.

Adjusting "fully up" position — "Up" limit switch, located immediately

above left end of automatic trap door, is tripped as door closes. If door does

not close fully, limit switch should be raised slightly. If door closes too tightly,

switch should be lowered slightly.

Remove steel plate attached to threaded neck of "up" limit switch by removing

hex nut securing it. Removing plate exposes three Phillips head machine

screws which hold limit switch bracket in place. Turning these screws clock-

wise will raise limit switch; turning them counterclockwise will lower it.

Raise switch only in quarter-turn increments. When operating properly auto-

matic trap door should close gently and rest against but not press on rubber

bumpers above it. Adjusting automatic door so that it closes too tightly will

damage screen.

Adjusting "fully down" position — "Down" stopping position may be ad-

justed by turning the white limit switch adjustment socket. The white socket is

located on the left end of screen roller and is accessible to a screwdriver/Allen

wrench (4mm or

") when automatic trap door is open. Access is easier

when bottom board is also open. (Do not adjust the yellow socket which is

next to and in back of the white socket). Turning the white socket counter-

clockwise will allow the viewing surface to run farther down. Turning it clock-

wise will shorten the viewing surface, causing it to stop in a less extended

position. At no time should viewing surface be unrolled enough to expose any

part of screen roller.
