MAKING THE CONNECTIONS
1. Connect a projector trigger cable to the projector. (Note: projector trigger cable not provided – the
installer needs to make the cord from a RJ25 cord, cut one end off and add the mono plug onsite.)
2. Connect the other end of the trigger cable to the Cima unit. (RJ25 plug)
HOW IT WORKS
When the projector is turned on or off a signal is sent to the controller within the motor and will trigger
the screen to move up or down.
If there is a sudden change in direction, the motor is paused for 1/2 second before reversing direction.
This is to prevent strain on the motor mechanism, and to prevent damage to any material controlled
by the motor. Relays are automatically de-energized after 120 seconds of operation to reduce power
consumption.

OPERATING THE SCREEN
DESCRIPTION
The method you use to raise and lower the screen depends on the type of switch control device you
have selected.
When you lower or retract the screen, it will stop at its preset limit. If an obstacle (such as a person or
furniture) is in the path of the screen as it is lowered, use the switch control to stop the screen’s motion
(it will not automatically stop if it hits an obstacle).
The motor is designed to be used for short operations such as lowering the screen in preparation for
viewing. The motor is not designed for continuous duty. If the motor operates continually for more than a
few minutes, it may automatically shut off to prevent damage from overheating. If the motor occasionally
needs to be run more than normal, for example during initial setup and positioning, allow time for the
motor to cool down.
In general, when the screen is not in use, you should store it in the fully retracted position.
i CAUTION
Do not operate the motor when any of the following occurs:
`
The unit emits any smoke, heat, abnormal noise or unusual odor.
`
The unit is damaged in some way, such as damage from a water leak.
If any of these situations occurs, call a qualified service person.
SWITCH & TRIGGER WIRING
The 3-button, low-voltage keypad operates with
only 3 conductors; common, up & down. The
“Stop” function shorts both directions internally
to common. You can use both switching functions
simultaneously by simply connecting a splitter to
the Cima RJ Input jack. The trigger input is only a 2
conductor connection.

Cima AC15
ADJUSTING THE SCREEN EXTENSION
i CAUTION
Improper adjustment of the limit switches can cause irreparable damage to the screen itself, resulting
in voiding the factory warranty.
DESCRIPTION
The extension and retraction limit switches have been preset at the factory. In general, we advise you
to avoid readjusting these switches. In some cases, to enable proper alignment of the displayed image
on the screen, you may need to adjust the extension of the screen. If adjustment to the extension is
necessary, carefully follow these instructions.
WARNING!
The screen is fully retracted when the batten is flush with the bottom of the case. Do not attempt
adjustments with the yellow retraction (UP) limit switch that will further retract the screen. Incorrect
adjustment of the switch will cause severe screen damage. Please consult the factory if you have
any questions.
ADJUSTING THE SCREEN EXTENSION
You can increase the extension of the screen up to 3” (7.6 cm) past the factory preset stop, or you can
decrease the extension by approximately 4-6” (10 - 15 cm) from the factory preset stop. Do not attempt
to modify the screen extension beyond these recommended amounts.
The limit switches are located on the left side (audience left) of the screen roller tube inside the case,
after removing the dust cover.
To increase the screen’s fully extended (screen down) stop position:
1. Lower the screen to its current stop position.
2. Remove the dust cover to locate the white extension (down) limit switch on the left side of the
screen tube (audience left). Use a small electrician’s style screwdriver or a 5/32” (.4 cm) hex wrench
to turn the switch in a counterclockwise direction. If the power is still on, the screen will drop incre-
mentally as the switch is turned.
Note: One complete turn of the switch will make approximately a 3/4” (2 cm) change in the screen’s
stop position.
16 Stewart Filmscreen
ADJUSTING THE SCREEN EXTENSION (CONTINUED)
To decrease the screen extension:
1. Lower the screen until it is extended about halfway down.
2. Remove the dust cover to locate the white extension (down) limit switch on the left side of the
screen tube (audience left). Use a small electrician’s style screwdriver or a 5/32” (.4 cm) hex wrench
to turn the switch in a clockwise direction.
Note: One complete turn of the switch will make approximately a 3/4” (2 cm) change in the
screen’s stop position.
3. Activate the screen in the down direction until it reaches the newly reduced stop position. Repeat
this procedure until the desired stop position is reached.
Once you have made the adjustment, whenever you lower the screen, it will automatically stop at the
new position.
Note: The yellow “UP” limit switch is to stop the motor in the retracted position. We advise not adjusting
this switch as to avoid possible screen damage should the switch get mis-adjusted. It is recommended
that you make a note of any changes made to the factory preset.
With reasonable care, you may expect many years of dependable use of your Stewart projection screen.
We encourage you to keep your screen clean. To protect your screen when it is not in use, store it in the
fully retracted position.
Avoid getting any foreign material on the screen, as cleaning may prove very difficult. It may not be
possible to remove scratches, paint, ink, etc.
GENERAL MAINTENANCE
Treat your screen surface delicately. Special attention to these instructions should be followed when
cleaning.
`
A draftsman-style brush may be used to lightly whisk away any loose dirt or dust particles. (This
type of brush is usually available at office supply stores.) Stewart Filmscreen has an optional screen
cleaning kit that contains the proper type of brush. Contact your dealer if you would like to obtain
this cleaning kit.
`
Particles left on the screen when it is retracted into the case may form an impression on the screen
surface. Periodically wipe the back of the screen with aclean damp cloth.
`
For tougher spots, you can make a cleaning solution using a water-based detergent and warm water.
To make the solution, mix one part Simple Green, 409, or other water based industrial cleaner with
three parts warm water. Moisten a clean cotton cloth or Q-Tip with this solution, moisten the stained
area, and gently lift off the stain. Never use an aggressive scrubbing action as you could damage the
screen surface by removing the optical coating. Remoisten the area with clean water and dab dry
with a clean sponge or cotton cloth. Any residual watermarks will evaporate on their own in a few
minutes.
Do not use any other cleaning materials on the screen. Contact the factory if you have questions about
removing difficult spots.
WEEKLY MAINTENANCE
To maximize the longevity of your Cima screen we recommend the screen be deployed overnight at
least once a week. If using a 3rd party control system to deploy your Cima screen, you may be able to
program the 3rd party system to automatically deploy your Cima screen once a week.
REPLACEMENT PARTS & SERVICE
No user-serviceable parts are contained within the unit. Contact your dealer or the factory if you require
part replacement or service.
