Installation/Operating Instructions

Envoy Electric Projection Screen by Draper

Hanging Screen

General:

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 varie ty of ways. See typical installation detailed on page

2. 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. Draper provides eyebolts to use in hoisting the screen. 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 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 unit electrical connections have been made and

screen has been operated successfully.

Caution

1 Read instructions through completely before proceeding.

2 Follow instructions carefully. Installation contrary to instructions invalidates

warranty.

3 Do not lift case in center. Lift the ends simultaneously to avoid damage

to case and surface.

4 Before removing screen from crate, check for damage and to make sure

all parts are included.

5 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.

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

7 Nothing should be fastened to screen dowel, viewing surface or auto matic

trap door.

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

packing material.

9 Screen operates on 110-120V, 60 hz., 1.1 amp current draw.

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

to be operating properly prior to shipment.

Electrical Connections

Screen operates on 110-120V, 60 hz., 1.1 amp current draw.

Junction box is located just above bottom board near left end of screen. Bottom

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

screwdriver. Automatic trap door is held shut by viewing surface and must not be

forced open. Removal of junction box cover 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.

All operating switches should be “off” before power is connected.

Operation

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.

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

Limit Adjustments (Standard & Standard Quiet Motors)

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.

Tools needed: Flashlight, small ﬂathead screwdriver/Allen wrench (4mm or

5/32").

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 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

“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 clockwise will raise limit

switch; turning them counterclockwise will lower it.

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

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.

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.

Key Operated Switching — Two kinds of key-operated switches are optionally

available with this unit. The key-operated power supply switch controls power to 1

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. A three-position 2

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.

Caution: Do not remove the roller assembly from the case unless

necessary for repairs. If the roller assembly is removed, be sure motor

is fully re-seated in the bracket, and re-secure it carefully with the motor

retaining spring (see diagram below).

Limit Adjustments (Built-in Low Voltage Motors)

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.

1 Connect the ILT switch to the motor via the terminal blocks, or via the

modular port using four conductor modular cable. When using modu-

lar cable, the cable connectors MUST NOT be crimped in reverse, as

with standard telephone cable. (For a Dry Contacts Wiring Diagram,

see page 3.)

2 Set the slide switch to the lower position. Press and hold the DOWN

button on the switch to move the viewing surface to the desired lower

limit. If the screen moves in the opposite direction, release the DOWN

button and press and hold down the STOP button for four seconds.

This will reverse the operation of the UP and DOWN switches.

3 Move slider switch into center position. Wait a couple of seconds.

Please Note: If you move the slider switch from down to up in one

motion it sets the two limits in the same position.

4 Set the slide switch to the higher position. Move the viewing surface

to the desired upper limit by pressing and holding the UP button on

the wall switch.

5 Return the slide switch to the center position to return to normal

operation.

6 To set the viewing surface to an alternate format position, move the

viewing surface to the desired position and press the STOP button.

Press and hold the STOP button for at least three seconds to record

the position.

Please Note: Pressing and releasing the UP button on the switch will

move the screen to its upper limit. Pressing and releasing the DOWN

button will move the screen to its lower limit.

While the motor is in motion, pressing the STOP button for less than

two seconds will stop the viewing surface at its present position.

Once the motor is stopped, pressing the STOP button will move the

viewing surface to its alternate format position.

Pressing and holding the STOP button, when the motor is at rest or

in motion, for at least three seconds will record a new alternate format

position.
