Installation/Operating Instructions

Envoy Electric Projection Screen by Draper

Caution

① Read instructions through completely before proceeding.

② Follow instructions carefully. Installation con trary 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 un ob struct ed to permit prop er

operation of automatic trap door, and access to bottom panel for mak ing

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

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

Hanging Screen

General:

When locating viewing surface and checking clearance for screen’s op er a tion, remember surface is centered in case. Screen is normally recessed above ceil ing and may be installed in a varie ty of ways. See typical in stal la tion detailed on page

2. Re gard less 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 sup port ed so that vibration or even

abusive pulling on viewing surface will not weaken in stal la tion.

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 per mit ted to operate freely. Front and back of case must be straight—

not forced to warp or bow. Hinges must be free from mas tic or paint buildup,

and doors must be un ob struct ed 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 view ing

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.

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. Bot tom board is held closed with fl athead screws and may be opened with a Phillips screwdriver. (Automatic trap door is held shut by view ing sur face and must not be forced open.) Re mov al of junc tion box cover plate ex poses red, black and white pigtail leads and green in ter nal ground wire per wiring di a gram 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 fi rst operated, be cautious! If automatic trap door does not drop open im me di ate ly when switch is fl ipped “down”, re turn switch to “off” and free trap door and/or recheck elec tri cal con nec tions before proceeding. Cycle unit down and up several times to confi rm sat is fac to ry operation.

110-120V Single Station Control — 3-position up-off-down switch per mits operation to be stopped at any point. Factory adjusted limit switch es automatically stop screen when fully down or fully up.

110-120V Multiple Station Control—Switches are similar in ap pear ance to

110-120v Single Station Control. Screen stops when switch is re leased and may be re start ed in either direction. Factory adjusted limit switch es stop screen automatically when fully up or fully down.

24V Control — Three-button up-stop-down switch es stop at any point desired, operate in any sequence. Factory adjusted limit switches au to mat i cal ly stop screen when fully up or fully down.

Key Operated Switching — Two kinds of key-operated switches are op tion al ly available with this unit. ① The key-operated power sup ply 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. ① A three-po si tion key switch per mits 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.

Limit Adjustments (Standard & Standard Quiet Motors)

Tools needed: Flashlight, small fl athead screwdriver/Allen wrench (4mm or 5 /

32

").

Screen settings have been factory set as ordered and should not normally require further adjustment. However, if you fi nd it necessary to adjust for more or less viewing area, proceed as follows.

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. When running up, the dowel should never wrap over the roller. When run to the down limit, a minimum of 1¼ wraps of fabric must remain on the roller.

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

To Reduce Screen Drop

"DOWN" LIMIT ADJUSTMENT

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.

CAUTION: At least 1¼ wraps of fabric must remain on the roller when screen is at the down limit!

"UP" LIMIT ADJUSTMENT

“Up” limit switch, located im me di ate ly 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 re mov ing hex nut securing it. Removing plate exposes three Phillips head ma chine screws which hold limit switch bracket in place. Turn ing these screws clockwise will raise limit switch; turning them coun ter clock wise will lower it.

Raise switch only in quarter-turn increments. When operating prop er ly 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.

Limit Adjustments (Built-in Low Voltage Motors)

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

via the modular port using four conductor modular cable.

When using modular 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 opera-

tion of the UP and DOWN switches.

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

onds.

Please Note: If you move the slider switch from down to up in one motion it sets the two limits in the same postion.

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 nor-
