Description
Operation
Both the STI inputs and LV can be used at the same time, as illustrated
above. There is a built in de-bounce function whereby the change of a
signal must exist for a time greater than 80ms. Any signal less than
80ms is ignored
The operation of the STI is based on the state of the LV and STI inputs as
follows:
The STI-100 supports both contact closure and voltage sensing input.
There are two close contact inputs: one for up and one for down. These
inputs require an external switch or relay to short these inputs to ground.
The voltage sensing input will trigger an up or down motor movement based
on the voltage level. A voltage level between 5vdc and 12vdc will drive the
motor down, a 0vdc will drive the motor up. A signal changing from 0 to 12v
will trigger the down, a transition from 12v to 0v will trigger an up. All inputs
are protected from static discharge

If there is a change of 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

1. Raise the case into the ceiling.
4. Attach the removable dust cover by sliding in to the housing.
Refer to Figure 8.
During installation of the Cima Above Ceiling housing into the ceiling opening,
be advised that damage can occur to the screen. Perform the following actions
to avoid damage:
Wear clean gloves throughout the installation process to prevent damage to the
screen housing or screen material
3.Fasten the Cima screen housing mounting brackets to the
threaded rod or beams above the ceiling.
When installing the Cima housing assembly make sure that the screen batten
never contacts or strikes any objects as damage may occur as a result.
2.Attach the housing securely then plug in the STI wiring and
terminate the power.
STEP 3. INSTALLING THE SCREEN CASE INTO THE CEILING

The method you use to raise and lower the screen depends on the type of
switch control device you have selected.
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.
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.
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.
Improper adjustment of the limit switches can cause
irreparable damage to the screen itself, resulting in voiding
the factory warranty.
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.
©2015 Stewart Filmscreen Corporation
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).

ADJUSTING THE SCREEN EXTENSION
Caution
Cima Above Ceiling ElectriScreen: Owner’s Manual 17

Modifying the extension of the screen
You can increase the extension of the screen up to 3" (7.5 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
incrementally 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.
18
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.

SCREEN TENSION ADUSTMENT (WHERE REQUIRED)
To correctly adjust the batten setting position and side line length on
your Cima screen, it may be necessary to loosen the existing side line
attachment screws. After the adjustment has been completed, the
batten weight will be increased on the screen while decreasing the side
line tension.

This procedure can improve the overall flatness of the screen primarily in
the lower section of the image area. In many instances, the screen's
factory deployment setting has been reduced at the site and therefore
this batten adjustment is necessary:
The objective is to thread the screw into the ferrule just enough to get
a very low amount of side line tension (approximately 3 to 4 turns).
The side lines will now have less tension which is desirable. The result
is that more batten weight will be distributed on the screen once this
adjustment is completed. You should see a slight improvement when
finished, however, it will take some time for this adjustment to fully take
effect (stretching screen) thereby eliminating any wrinkles, waves, or
puckers
Cima Above Ceiling ElectriScreen: Owner’s Manual

With reasonable care, you may expect many years of trouble-free 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
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 a clean damp cloth.
For tougher spots, use a solution of mild detergent and water.
Rub lightly using a sponge. Blot with a damp sponge to absorb
excess water. Residual water marks will evaporate within a few
minutes. Let the screen air dry completely before retracting.
Do not use any other cleaning materials on the screen. Contact the factory
if you have questions about removing difficult spots.
Replacement parts and service
No user-serviceable parts are contained within the unit. Contact your dealer
or the factory if you require part replacement or service.
©2015 Stewart Filmscreen Corporation
Treat your screen surface delicately. Special attention to these
instructions should be followed when cleaning.
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.
