can be moved up one inch to accommodate taller projectors. Make the neces-
sary connections and plug the power cord of the projector into the receptacle
provided in the electrical chassis.
Power to the Revelation should be turned
off any time electrical connections or mechanical adjustments are made
to the Revelation!
Cycle the mirrored door down to the lowered position. You
are now ready to move on to adjusting the image to the screen.
Adjusting Image
First, use your projector’s operating manual to establish proper orientation of
the image and adjust the lens position to achieve the desired image width and
location.
Next, use the Revelation's adjustments to adjust the height of the image on
the screen.
The Revelation has two adjustments:
1
Always start by sliding the inner pan which holds the projector either back-
ward or forward depending on desired location of image. Sliding the inner
pan towards the projection screen will change where the image strikes the
mirror on the door, and lower the projected image. Inner pan has a travel
range of approximately 8".
2
Opening the mirrored door even further into the room will lower the
projected image. The limit switch is factory set to let the door open into
the room at a 45° angle. The door can open approximately 10° farther
by changing the limit switch’s position. You can also tip the front of the
projector up toward the first mirror. This adjustment allows the image to be
projected farther down from the ceiling, but still introduces keystone into
the image. This adjustment offers the same adjustment feature as opening
the mirrored door up farther into the room without adjusting the mirrored
door's limit switches.
Adjust the door only if your projector is equipped with keystone correction or a
certain amount of keystoning can be tolerated.
To adjust the limit switch of the door:
TOOLS:
screwdriver/Allen wrench (

/

"); electronic level or protractor or other
tool to measure angles.
Turn the unit on and open the door to its factory set position. Record the angle
measurement.
Caution:
Any adjustments to the limit switches should be done with the
power to the Revelation turned off!
Locate the two limit switch brackets at the edge of the top mirror on the motor
side of the pan. The top bracket controls the downward travel limit of the door
and adjustments are made to this bracket. Note and mark current location of
limit switch bracket.
The bottom limit switch bracket is set at the factory for
proper closure alignment and should not need adjusting.
Use a

" Allen wrench to loosen the two screws on the limit switch bracket
and slide the bracket toward the electrical chassis. A slight adjustment to the
limit switch bracket will result in a significant movement of the door. It is rec-
ommended that the limit switch be adjusted in small incremental moves of
1
/
8
".
Tighten the screws. Keeping hands and tools clear of the limit switch, connect
the power. The door should open further. Record the new angle and check the
position of the image on the screen.
If the position of the image on the screen is satisfactory, close the door and
make sure the screws are completely tight.
If the position of the image needs adjusting, leave the door open, disconnect
the power, loosen the screws and slide the bracket toward the motor to open
the door more, or slide the bracket closer to its original position.
Check alignment of image and repeat adjustment procedure as neces-
sary. After all adjustments are completed, be sure to tighten all loosened
screws to inner pan and limit switch bracket!

Electrical Connections
Unit operates on 220 V a.c., 60 Hz. current.
Opening the access cover on the electrical control box exposes terminals
for field connections. Unit is shipped with internal wiring complete. Wire for
connecting unit to switch(es) and to power supply should be furnished by
electrician. Connections should be made in accordance with wiring diagram
on page 5, and wiring should comply with national and local electrical codes.
All operating switches should be “off” before power is connected.
Operation
Caution: Keep fingers and other objects away from unit when it is
operating. Serious injury or damage can result.
When unit is first operated, be cautious! If door does not begin to open
momentarily when switch is flipped “down”, return switch to “off” and free door
and/or recheck electrical connections before proceeding. Cycle door down
and up several times to confirm satisfactory operation.
Single Station Control
(CE Approved)—Moving 3-position switch to “down”
position will start door down. Moving switch to “up” will start door up. When
door is fully down or fully up, it will automatically be stopped by factory set
limit switches. Whenever switch is placed in center “off” position, operation will
stop.
Multiple Station Control
—Each switching station has a three-button switch
with “up”, “down”, and “off” buttons. Door starts up or down when appropriate
button is pressed, and may be stopped by pressing “off” button. Factory set
limit switches stop door automatically when door is fully up or fully down.
Key Operated Switch—
If ordered, a single station, key-operated three posi-
tion (up/off/down) switch is available for this unit.
Video Interface Control (VIC12, VIC12 Modified)—
This optional control
device allows the Revelation switch to control the operation of a Draper
motorized projection screen via relay.
Infrared or Radio Frequency Remote Control
(CE Approved)—A three-but-
ton transmitter is provided, with “up”, “down”, and “stop” buttons. Door starts
up or down when appropriate button is pressed, and may be stopped by
pressing “off” button. Factory set limit switches stop door automatically when
door is fully up or fully down.
Installing Projector
The Revelation has a grounded 220 V a.c., 60Hz outlet for projector power
supply. Power is supplied to this outlet at all times.
Holes are provided for power and control wiring.
Install a projector with the capability to invert its image.
Place the projector into the sliding inner pan so that the center of the projector
lens is aligned L to R with the center of the upper mirror. Position the projector
lens as close as possible to the upper mirror without the reflected light path
striking any part of the projector.
An extension plate is provided if the feet
of your projector rest inside the opening of the inner pan
. The extension
is designed to support the front legs of your projector and the folded up edge
can be used as a stop to help reposition the projector when removed. Adhere
the extension plate only after you have adjusted the image and marked the
position of the plate.
Establish exact placement through trial and error using the various adjust-
ments integrated throughout the design of the Revelation. The upper mirror
