The information presented in this section covers the
controls and functions for all currently manufactured
models of the KODAK EKTAGRAPHIC Ill Projector—as
well as the basic setup, preparation, use, shutdown, and
maintenance procedures for each projector.
As shown in the Projector Summary Chart earlier
(page 11), the EXTACRAPHIC II E Projector is the
most basic model and therefore will be described first.
The III ES, B, A, AS, and AT Projectors (which follow in
that order) have the same basic features as the III E
Projector, plus other features that make them
appropriate for specific projection requirements and
environments. Only features unique to each model (after
the II E) will be noted.
The FKTAGRAPHIC III Projector is noticeably different
in size and shape from the FKTAGRAPHIC Slide
Projector, Models E-2, B-2, AF-1, AF-2, etc, or the
German-made FKTAGRAPHIC Slide Projector, Model
S-AV2030 or Model S-AV2050.
The controls for the EKTAGRAPHIC III Projector are
located on the right side of the projector (as viewed
from behind the machine), and are easy to use (even In
a dark room) because the built-in illuminated control
panel keeps them visible. The sloping panel makes
viewing and operating the controls easier from either
the side or the back of the projector.
Three “sight lines” are built into the projector to aid
the operator in aligning the projector with the screen—
without turning the projector on: the edge of the
handle, the top of the control panel, and the groove
down the center of the housing on the left side are all
parallel to the optical axis of the projector, which makes
preliminary alignment easy even in a lighted room.

The Controls and Their Functions
Remote-Accessory Receptacle
The seven-contact remote-accessory receptacle accepts a
control plug from a number of remote-control devices,
such as the KODAK EKTAGRAPHIC Programmable
Dissolve Control, Model 2, the KODAK EC Sound-Slide
Synchronizer, and the KODAK EC-1 Remote Control,
which are described later in the “Accessories” section of
The Source Book. Many dissolve controls and
accessories from other manufacturers can also be
connected to the remote-accessory receptacle.

pins, two of which are not used.)
Please note that the interchanging of remote controls
between a III EE Projector and other FKTAGRAPHIC 111
models is not recommended; it will not damage your
projector; however, it will not add remote-focusing
capability.

KODAK
REMOTE CONTROL
The projector cord on the KODAK EKTAGRAPHIC
Programmable Dissolve Control, Model 2, has a seven-
pin plug that fits into the seven-contact remote-
accessory receptacle of the projector. Many dissolve
controls from other manufacturers have similar seven-
prong plugs and, hence, are compatible with
EKTAGRAPHIC III Projectors.
Power-Selector Switch
When the power-selector switch is set at OFF, neither
motor nor lamp operates, nor can they be turned on by
an accessory controller. When the power-selector switch
is set at FAN, the projector's cooling fan operates. The
projection lamp is lighted only if a dissolve control or
other external control is switched on. (The lamp will
not go on if the switch is set at the OFF position. This
avoids potential overheating caused by having the lamp
on but fan off.) Set the power-selector switch at the
FAN position when connecting two or more projectors
to a dissolve control. For single-projector use, move the
switch to LO to obtain maximum lamp life or HI for
maximum image brightness.
NOTE: The FKTAGRAPHIC lll Projector exhaust fan is
run a bit faster than those in US-made FKTAGRAPHIC
Slide Projectors to compensate for the projector's
greater slide illumination and consequent heat
generation capability. The configuration of fan exhaust
resembles that of EXTAGRAPHIC Slide Projectors—
exiting from the back at about a 45-degree angle
toward the left side (as viewed from behind the
projector).

projector) as you insert or withdraw the lens.
Also, when inserting the lens, position the threaded
rack of the lens barrel toward the lower left to engage
the pinion of the focus-knob shaft. |
Forward and Reverse Buttons
Briefly press the forward button or reverse button to
change your slides one slide space at a time. Holding
either button down will change slides rapidly.
Select Bar
The select bar enables you to rotate or remove the slide
tray at any time, whether the power is on or off. With
the power on, pressing the select bar down will stop the
slide-advance cycle at midpoint, with the slide-lift lever
raised, so the tray can be manually turned to any
position. To rotate the tray to another position (or
remove it from the projector) with the power on, press
the select bar and hold it down while turning the tray
to the desired slide (or to slide slot “O” for removal).
Push the select bar all the way down to its lowest
position if the tray is to be rotated with the projector
power-selector switch set at the OFF position.
NOTE: To prevent improper interaction between the
powered and manual select function, there is a
mechanical interlock to prevent operation of the power-
off select feature when the power switch is at the FAN,
HI, or LO lamp position. If you wish to remove the tray
when the projector is not receiving power, the projector
power-selector switch must be set at the OFF position.
The tray will not rotate with the power-selector switch
set at FAN, LO, or HI if the projector is not powered.

Shown below are the functions
controlled by each pin-number configuration
for the special-application receptacle:
Special-application receptacle
(contact identification as seen from the back of
the EKTAGRAPHIC III Projector).
Contacts
Required Function Description
1&3 Zero-Position Switch Connects to an internal single-pole single-throw normally open
switch. Contacts are closed when the projector slide tray is at any
position other than zero. These leads connect only to the switch
terminals. Do not exceed a switching load of 1 A at 30 V ас.
485 Shutter Switch Connects to an internal single-pole single-throw normally closed
switch. Contacts are open when a slide is in the projector gate and
the shutter is open. These leads connect only to the switch
terminals. Do not exceed a switching load of 1 A at 30 Vac.
788 Low-Voltage Supply For operating external equipment. The current is supplied by a
secondary winding on the main motor, isolated from the voltage
power, and is available whenever the main projector motor is
running. Supply is 25.5 V, 500 mA (1,2 À) maximum. Contact
number 8 is common (return) for the remote-control circuit.
Contact number 7 is the “hot” lead and is used with a slow-blowing
fuse. (Replacement requires disassembly of the projector by a
qualified technician.)
6&8 Forward-Tray Cycle Connects to the forward tray advance circuitry in the projector.
These contacts are connected internally to the remote-accessory
receptacle and an electrical connection made at either receptacle
will result in a forward cycle.
2&8 Reverse-Tray Cycle Connects to the reverse-tray advance circuitry in the projector.
These contacts are connected internally to the remote accessory
receptacle and an electrical connection made at either receptacle
will result in a reverse cycle.
Shell Plug Ground If a plug with a connecting shell is used, it is connected to the
projector frame (chassis) through the special-application receptacle
and to earth ground through the projector's power cable.
CAUTION: All equipment, cables, and connectors used with the special-application receptacle must be
assembled by qualified electronics personnel. All circuits connected electrically to the projector through the
receptacle must also comply with the Underwriters Laboratories, Inc, low-voltage, limited-energy circuit
requirements. (For safety reasons, there is a fuse limiting the amount of current that can be drawn.) Low-
voltage, limited-energy circuit requirements may be found in UL-122, Photographic Equipment, available from
Underwriters Laboratories, Inc., 333 Pfingsten Rd., Northbrook, IL 60062.

Setting Up Your Projector
Loading the Slide Tray for
Front-Screen Projection
First, arrange your slides on an illuminator so that all
the images are right-side up, with words and images
reading correctly from left to right, and in correct
projection sequence (in the order that you want them to
appear in the show). Then rotate each slide so that all
the images are upside down (do not flip the slide
around so that the opposite side of the film faces you).
Then number each slide mount consecutively in the
upper right-hand corner. (Do not skip this step.)
NOTE: Avoid using “sticky labels” to number the
mounts. Projector heat may eventually loosen them,
causing the slides to jam in the projector gate. Also,
most felt-tip pen ink smears when the mount is
handled. Use a permanent-ink pen, such as a Schwan-
Stabilo Pen No. 76P Medium or a Sanford’s Sharpie"
No. 3000.
Remove the lock ring or cover of the tray by turning
it counterclockwise. Before you load the FKTAGRAPHIC
Universal Slide Tray, Model 2, EKTAGRAPHIC Universal
Deluxe Covered Slide Tray, or CAROUSEL TRANSVUE
80 Slide Tray, be sure that the bottom metal slide-
retainer plate is locked correctly with the latch. The
formed end of the latch should be positioned in the two
notches. If it is not, turn the bottom metal plate until it
locks into position. (The Deluxe Covered Slide Tray has
only one notch.)
Insert the first slide of the program into slot number
1 of the tray, the second slide into slot number 2, etc.
Remember that the correct orientation of each slide for
front-screen projection is with the image upside down
and the correct-reading side of the film facing toward
the next higher number in the tray (inserted into the
tray in exactly the same orientation as you arranged
them on the illuminator). When the tray is loaded and
held right-side up in front of you, the mount numbers
should be positioned next to the outside circumference
of the tray and visible as the tray is turned 360 degrees.
After all slides are in the tray, replace the lock ring or
cover, turning it clockwise until tight. This locks the
ring to the tray and prevents the slides from falling out
if the tray is inverted (turned over) accidentally.
For instructions on loading the tray for rear-screen
projection, refer to the text box entitled “Front-Screen
Projection versus Rear-Screen Projection” at right.
Front-Screen Projection
versus Rear-Screen Projection
Rear-screen projection usually requires different
slide orientation in the tray slots (depending on
whether mirrors are used in the projector light
path, and if so, the number and arrangement of the
mirrors).

side up on the screen (from the viewing position of
the audience—not the projectionist) and reads
correctly from left to right.
Then orient all the other slides in the set the
same way, by reinserting them so that all the slide
mounts in the tray are positioned the same way

Operating the Projector
Simple Start-Up Procedure
The EXTACRAPHIC III E Projector enables the user to
project 2 x 2-inch slides in a wide range of transparency
sizes—including 126, 135, 828, 127, and 110. Follow
the instructions below to set up and operate your
EKTAGRAPHIC II E Projector.
® Unwind the required length of power cord from the
cord retainer located on the bottom of the projector
and plug it into a 110 to 125 V, 60 Hz power outlet.

* Check that the lock ring or cover on the tray is tight;
then invert the tray and turn the bottom plate of the
tray until it locks into position. (For the 140 Tray, it is
necessary to release the latch and turn the bottom
plate until the index hole is at the index notch.)
* Turn the tray upright and remove the lock ring or
cover. If the slide is undamaged, return it to the tray.
Replace the lock ring or cover; return the tray to the
correct slide position and resume your program.
® You can also turn projector power off and press the
select bar all the way down to aid in unjamming
the slide.
Alternative Projection Methods
Three alternative ways of projecting your slides are
possible:
® You can show slides without using a slide tray. А
single slide can be shown by inserting it, correctly
oriented (“right-reading” from left to right, and then
inverted) into the projector gate. Simply press the
select bar or slide-advance button to remove
each slide.
e You can use the KODAK EC Stack Loader (page 56)
for fast review of up to 36 slides in thin cardboard or
plastic mounts (in the forward projection mode only).
e Slides can be shown with the tray but without the tray
lock ring. By leaving the lock ring off, slides can be
inserted or removed for easy editing. Extra care is
necessary when handling the tray to avoid spilling
the slides.
NOTE: Be sure the slide mounts are consecutively
numbered.
(The EKTAGRAPHIC Universal Deluxe Covered Slide
Tray is handy for editing this way because the lower
tray sidewall exposes the slide corners.)
Long-Run Applications
In normal use, the parts of the projector that are
subject to wear have about equal life expectancy and
require no special maintenance. However, if you expect
to run your projector for an exceptionally long period of
time, you must observe these precautions:
® Provide for unrestricted air flow to and from the
openings in the projector housing.
* If the projector is to be used in a small, enclosed
area such as a cabinet, furnish an exit for warm air
released from the rear grill vent. In some cases,
additional forced-air ventilation may be needed.
®* Keep air circulating through the projector. Air at
normal room temperature is satisfactory.
Shutdown
You should adopt a standard shutdown procedure after
each presentation, similar to the one that follows. This
procedure will help you be ready for the next show and
will also help provide proper care for the projector.
® Rotate the tray to the “0” position while pressing the
select bar.
e Turn off all power to the projector by moving the
power-selector switch to OFF.
NOTE: Rapid cooling of an EKTAGCRAPHIC III Projector
or FKTAGRAPHIC Slide Projector after each use is not
necessary nor recommended.
Pulling cool air over the lamp and glass parts may
cool them too fast and increase the chance for breakage.
Also, it's too easy to forget and leave the fan running,
which shortens projector motor life. However, if the
projector must be handled immediately after the show,
or if the projection lamp has burned out and needs to
be rapidly cooled before being exchanged for a new
lamp. the fan can be run to speed up cooling. (A spare
KODAK EC Lamp Module can also be used to speed up
lamp replacement. See page 21.) The right-rear corner of
your projector may be warm for several minutes after
you switch off the power. The maximum temperature
reached, however, will be well below the danger point
for the projector, lamp, slide tray, slides, and the
operators fingers.
* Remove the slide tray. If the projector is unplugged,
simply move the projector power switch to OFF,
depress the select bar all the way down, and rotate the
tray to the “0” position. Then remove the tray.
If the projector will not be moved before the
next show
e Retract the elevation foot and leveling wheel.
® If desired, remove the projection lens. (Release it by
pushing up the lens focus and release knob. Then
grasp the projection lens and pull it out.)
® Unplug the remote control, if used.
® Disconnect the power cord and wrap it around the
cord retainer underneath the projector.
® Place the projector in a storage or travel case
for protection.
Serial Number
The projector serial number is printed on the label
affixed to the cord wrap retainer underneath the
projector. Record this number—as well as the model
identification and the date and place of purchase — for
future reference.

Planning Ahead for Multiple
Slide Presentations
If vou intend to leave your equipment in place for a
repeat performance do the following:
# Lock the door to the projection area, if possible.
* When leaving an unenciosed projection area,
make a sign such as “Do Not Move Projectors
and place it near your equipment. If you are not
using projector “piggyback” stands or multiple-
projector “stacking” stands (which hold
projectors tightly in position), you can place a
piece of masking tape under each projector foot
and trace the location of each foot on the tape. If
the projectors are moved accidentally, they can
easily be replaced in the correct position.
If vou remove the slide trays from the projectors.
keep them in order so they can be placed back
onto the projectors quickly and in correct
sequence. KODAK EATAGCRAPHIC Tray Bands
(see page 57) provide a good method of
identifying and organizing your slide trays.
If you leave the equipment set up and trays on
projectors, return trays, audiotapes, and other
controls to the starting position and. if possible,

Projector Maintenance
Before doing any projector maintenance or cleaning of
your projector, be sure it is cool Disconnect the power
cord from its outlet. It is also a good practice to remove
the slide tray plus the remote control and any other
cables.
Replacing the Projection Lamp
Be careful! The lamp may be hot. If you are in a hurry,
run the fan until the lamp and lamp module are cool, or
use a cotton cloth to protect your fingers when you
handle the warm lamp module and lamp.
To replace a burned-out lamp, open the lamp door by
pressing down on the latch.

Some Advantages of a
Separate Lamp Module
KODAK EC Lamp Module
All KODAK EKTAGRAPHIC 111 Projectors are
provided with the lamp module described earlier
under “Replacing the Projection Lamp. on page 20.
The lamp module offers some not-so-obvious
benefits for single-projector as well as multi-image
presentations.
Since it contains a projection lamp. mirror, heat-
absorbing glass, and coated condenser lens. AV
professionals can replace a burned-out lamp with a
spare module (equipped with a new lamp) in a
matter of seconds— without disturbing critical
projector alignment and without losing the
attention of the audience.
This quick lamp-change capability reduces the
need to “relamp” before important multi-image
programs and thus avoids the accumulation of
expensive half-used projection lamps. It also
simplifies the cleaning of optical parts and helps to
prevent burned fingers.
The lamp module—complete with condenser
optics and heat-absorbing glass—is available as an
accessory from most dealers in Kodak audiovisual
products. Refer to KODAK EC Lamp Module,
CAT No. 145 0154. for pricing and ordering
information.
Cleaning the Projection Lens
Remove the projection lens by pushing the lens focus
and release knob up as you withdraw the lens. Blow off
any loose grit. Then wipe both surfaces of the lens with
KODAK Lens Cleaning Paper, or with a clean cloth
moistened with a single drop of KODAK Lens Cleaner.
Fingerprints reduce the brightness and clarity of screen
images; a little dust does not.

Cleaning Condenser Optics
CAUTION: The heat-absorbing glass could shatter
unexpectedly. Always wear safety glasses.
Allow the glass to cool before handling. Be careful!
Anytime the glass is exposed, keep it covered with a
cloth to confine potential shattering; handle the
glass gently.
Open the lamp door and remove the lamp module as
described on page 20. Next, loosen the small retaining
screw and raise the hinged bracket. Then carefully lift
out the condenser lens and heat-absorbing glass and
place them in a soft cloth.
HINGED
BRACKET
RETAINING SCREW
CAUTION: Damage to both the slides and the
projection lens can be expected if the projector is
operated without the heat-absorbing glass in place.
Wipe the condenser lens and heat-absorbing glass
with either KODAK Lens Cleaning Paper or a clean,
soft, lintless cloth.
Do not leave fingerprints on the surfaces. Use a soft
cloth to replace the lens and glass. Lower the bracket
and tighten the retaining screw.
Invert the lamp module to reach the mirror through
the opening. (The mirror is permanently aligned and
should not be moved.) Wipe the mirror surface as
described above for the optics.
Slide the module back into the projector as described
earlier; then close the lamp door.
If You Modify the Projector
If you modify your projector, obliterate the UL and CSA
labels. Modified equipment must conform to electrical
and other appropriate codes and to safety requirements.
22
Allowing Proper Ventilation
If you use your projector in a confined or dusty area—
particularly where a wall or partition blocks the fan
exhaust— poor ventilation may cause overheating. If the
built-in thermal fuses open and the projector stops,
contact a Kodak Equipment Service Center or other
competent repair service to have the fuses replaced and,
if necessary, your projector repaired.
Thermal Fuses
Your projector has two thermal fuses—one at the
motor and one at the projection lamp—to prevent
dangerous overheating in case of ventilation blockage,
exhaust fan failure, or motor failure. If overheating
causes the fuses to open, this indicates that the
projector has been hot enough to cause possible
damage. The projector should be checked and repaired,
if necessary, hy a qualified service technician at a Kodak
Equipment Service Center or other competent
repair service.
The Purpose of Thermal Fuses in
KODAK EKTAGRAPHIC Ш
and EKTAGRAPHIC Slide Projectors
Q. What is a thermal fuse? How is it different
from other electrical fuses?
A. A thermal fuse works like an ordinary
household fuse, except that it is sensitive to
temperature rather than current. In other
words, the thermal fuse opens a circuit and
shuts off the electricity when the temperature
is too high.
Q. Why are there thermal fuses in KODAK
EKTAGRAPHIC Slide Projectors?
A. They are there for safety. Their purpose is to
shut off electricity in the projector before the
temperature rises high enough to be a fire
hazard.
Q. Do the thermal fuses shut off the projector
before high temperatures can shorten
projector life or damage slides?
A. No. that is a common misconception.
Temperatures may become too high for
optimum motor life or maximum slide life, but
the thermal fuses won't open, so the projector
will keep running.
Q. Then why not use thermal fuses that open at
a lower temperature —so the projector and
slides will be protected?
A. It is not practical. Operating a motor even at a
low temperature will eventually wear it out;
and projecting a slide, even at a low
temperature, might eventually cause some dye
changes in the transparency.
FAN (AIR
EXHAUST)
THERMAL
FUSES
. Then why use thermal fuses at all in
EKTAGRAPHIC Slide Projectors if the fuses
don’t protect the projector and slides?
. As we said, the thermal fuses are used to avoid
hazards to surroundings not to avoid high
temperature operation of the projector.
Sometimes people operate slide projectors in
hot or dusty environments harmful to slide or
projector life. But the user may feel that the
reduction in slide and projector life is
worthwhile because the presentation is
important and effective. However. if the
thermal fuses opened whenever the air
temperature is higher than ideal, the
presentation would be ruined.
. Why aren't the thermal fuses user
replaceable?
. Because a burned-out fuse indicates that there
may be a projector problem that needs
correction before the projector is used again.
Experience indicates that replacing a thermal
fuse without correcting the cause often results
in another fuse burn-out.
. What causes thermal fuses to burn out?
. It could be projector wear-and-tear from very
long use. dirt in the ventilating air, an
electrical short, low or high power source
voltage, or other conditions that cause motor
overload and projector overheating.
. You mean, external conditions such as
restricted airflow, paper piled up against
projector air intakes, or blocked projector-
exhaust airflow?
. Yes. Even if these conditions are corrected after
a thermal fuse has opened, the projector
should be thoroughly checked by a competent
technician because the projector has been
overheated. possibly causing more projector
damage.
. | have heard of people who wire across the
thermal fuse contacts and say they have no
trouble.
. That is courting trouble. It is similar to putting
a penny in an old-fashioned fuse holder. A
“bypassed” thermal fuse in a slide projector
usually causes reduced projector and slide life
because of too much heat. Of course, defeating
a safety feature means increased danger for
yourself, other people. your environment, and
your property.
. Well, if the projector thermal fuses are not
intended to protect the projector and slides
from overheating, what can EXTAGRAPHIC
Il and EXTAGRAPHIC Slide Projector
owners and users do to provide such
protection?
. Usually no problems will occur if vou follow
the instructions in the “User's Instruction
Manual” packed with every EXTAGRAPHIC
Slide Projector.

AUTOFOCUS ON/OFF SWITCH
The Controls and Their Functions
Autofocus On/Off Switch
A built-in electronic autofocus mechanism monitors the
position of each transparency in relationship to the lens.
It is controlled by the autofocus on/off switch. After the
first slide is focused by the user, the mechanism
automatically maintains the distance between the lens
and the front surface of the next slide, near the center.
The front surface is film in an open-frame mount and
glass (instead of film) in a glass-mounted slide.
For slides mounted the same way (all glass, or all
plastic, etc), focus the first one and then leave the
autofocus switch on to maintain focus.
Leave the switch off when your slides are a mix of
open-frame (cardboard or plastic) and glass or if the
divisions on some multiaperture slides or matte-surface
write-on slides make the autofocus mechanism motor
run continuously. With some mixed open-frame and
glass mounts, one or the other may be out of focus; you
can refocus for each type when necessary or determine
and set an acceptable overall focus.
You may also wish to keep the autofocus switches of
your projectors at the OFF position when presenting
dissolve or multi-image programs.

Answers to Some Common
Questions about the KODAK
EKTAGRAPHIC II Projectors
Q.
A.
. Why doesn't the image fill the built-in viewer
Will the larger size of the EXTAGRAPHIC Ш
Projector create more keystoning?
It's not likely. The actual increase in projector
size is not great. The difference in minimum
spacing from one projector to the next one 15
inconsequential at ordinary projection distances.
with the projection lenses ordinarily used.
. Will the 16-degree elevation capability of the
EKTAGRAPHIC II Projector cause keystoning
when fully used?
. Anytime the lens axis is not at right angles to
the projection screen, there will be keystoning.
Increasing the elevation angle will increase
kevstoning on a vertical screen. Usually,
keystoning caused by an approximately 16-
degree-projection angle is not objectionable for
single image use (one projector, or a dissolve
control with two projectors).
(screen) on the EKTAGRAPHIC II ES and AS
Models?
. There is some space around the image when
using smaller slide formats so the popular 24
x 36 mm horizontal format can be seen either
as a horizontal or a vertical image. If super
slides are used, the image fills the screen.
. What happens if the high-output EXW lamp
intended for the EXTAGRAPHIC Hl Projector
is used in a CAROUSEL 4000 or 5000 Series
projector?
. The CAROUSEL Projector will overheat. The
safety thermal fuse in the lamp area could open.

. We've been told that the KODAK EC Lamp
Module supplied with the EXTAGRAPHIC IM
Projector is available as a separate product.
Can it be used in CAROUSEL 4000 and 5000
Series projectors?
. Yes, but that still doesn't permit using the high-
output EXW lamp. The cooling of the
CAROUSEL 4000 and 5000 Series projectors 1s
not sufficient for the lamp, and the thermal
fuse could open.

Operating the Projector
Quick Start-Up
® Plug the projector into a 110 to 125 V, 60 Hz power
outlet. (The models B-2AR, AF-2K, S-AV2030, and
S-AV2050, described later in this section, have
different power requirements.)
* Place a loaded slide tray on the projector with the “0”
slide slot aligned with the gate index of the projector.
® Move the projector power-selector switch to the LAMP
position for single-projector use. (If light from the
projection lamp spills onto the screen when the
projector is turned on, the automatic dark-screen
shutter in the projector is not engaged. Simply press
the select bar on the projector once to engage the
automatic dark-screen shutter so the projection lamp
light is blocked.)
® When using a dissolve control, move the power-
selector switches of your projectors to the FAN
position.
e Lower the room lights, and push the forward button
on the projector to project the first slide.
® Focus and align the image, and proceed with your
program.
If the Slide Tray Jams
[f the slide-changing mechanism will not operate
because a defective slide is caught in the gate, use a
coin to remove the tray to correct the problem. For
detailed instructions on how to release the tray, refer to

Shutdown
You should adopt a standard shutdown procedure after
each presentation, similar to the one that follows. This
approach will not only help you to be ready for the next
show but will also help provide proper care for the
projector.
e With projector power on, rotate the tray to the “0”
position while pressing the select bar.
* Turn off all power to the projector by moving the
power-selector switch to the OFF position.
NOTE: Rapid cooling of the projector after each use is
not necessary nor recommended. However, if the
projector must be handled immediately after the show,
the fan can be run to speed up cooling.
® Remove the slide tray.
If the projector will be moved before the next show
e Retract the elevation wheel and leveling wheel to help
prevent damage in transit.
e [f desired, remove the projection lens.
* Unplug the remote control (or the dissolve control
cords, if used).
® Disconnect the power cord from the power source, and
place the projector in a suitable container or travel
case for maximum protection.

The Model B-2 Projector has all of the features,
functions, and maintenance requirements of the Model
E-2 Projector, plus remote focusing, remote forward and
reverse slide-change capability, and a four-position
power-selector switch for OFF, FAN, and LOW and
HIGH lamp settings.
The Controls and Their Functions
Power-Selector Switch
When the power-selector switch is set at FAN, the
projector's cooling fan will operate but the projection
lamp will not be lighted (unless the projector is
connected to a dissolve control). Set the power-selector
switch at FAN for connection of two or more projectors
to a dissolve control.
The LOW and HIGH positions on the power-selector
switch provide added versatility to the Model B-2
Projector. For single-projector use, move the switch to
LOW to obtain maximum lamp life or HIGH for
maximum brightness.

Operating the Projector
Operation of the B-2 Projector is the same as the E-2
Projector, with the addition of the four-position power-
selector switch as well as the remote focus and remote
forward and reverse slide-change capabilities described
earlier.
Projector Maintenance
Refer to the E-2 Projector instructions (page 33) for
detailed maintenance procedures.
The Model B-2AR Projector has all of the features,
functions, and maintenance requirements of the Model
B-2 Projector, with the additional capability of operating
on either 110 to 130 Y or 220 to 240 Y, 50 or 60 Hz.
The projector adjusts automatically to the power supply
and is designed for international use.
Voltage Sensing Characteristics of
the EKTAGRAPHIC Slide Projector,
Model B-2AR
When the projector is connected to a power
source and turned on, the detection circuit in
the projector will connect the motor and lamp
directly to the power source if the power is in the
110-130 V range. If the circuit is 220-240 V. an
autotransformer in the projector is brought into
the circuit, so the voltage is cut approximately in
half for both the motor and lamp.
In addition to this major automatic switching
function. the projector detection circuit also brings
into play a low-voltage boost-or-buck (increase or
decrease) winding on the transformer of the
projector.
Thus. if the voltage is 110 V, it is boosted about
8 V to supply approximately 118 V to both the
lamp and the motor. If the voltage is 127 V
(common in some countries that have 50 Hz
power). the voltage is bucked (decreased), to supply
about 119 V to the lamp and motor. The action is
similar at the high and low end of the high-voltage
(220-240 V) range. so that again, about 117-120 V
is supplied to the lamp and motor.
The crossover point is about 117 V for the lamp
and motor. Below that point, the voltage increases
a few volts: above it. it decreases (bucks) a few
volts. This provides more consistent light output
and lamp life. and also proper motor performance.
If voltage fluctuated only slightly around the
crossover point, light output would fluctuate as the
boost-buck coil switched first one way and then the
other. This would be undesirable, because of
changes in the light output and relay “chatter.”
Therefore, a lag (or hysteresis) has been built into
the circuit. so the light output will not fluctuate
with small changes in voltage.
(CONTINUED)
35
However, there may be instances when voltage
fluctuations will be large enough to cause the
detection circuit to change the boost-buck coil and
cause unwanted projection-light variations. For
example, if a long lightweight power extension
cord is being used, with one projector lamp lit in a
two-projector dissolve pair. line voltage would be
125 V at the projector. This would cause the
detection circuit to subtract the small voltage.
supplying about 117 V to the projectors and the
lamp which was lit.
At about the midpoint in a dissolve. lamps are lit
in both projectors. drawing almost their full
current. If this load were sufficient to cause the
voltage to drop to perhaps 114 V (because of the
lightweight extension cord). the sensing circuits in
the projector would change the low-voltage coil
from buck to boost-—and the light levels of both
projected images would immediately increase.
As the dissolve progressed, the off-going lamp
would be reduced in brightness until it drew either
no current or negligible current. This could permit
the line voltage supplying the projectors to rise
again. so the sensing circuit would again be
activated, reducing the voltage and illumination.
Occasionally. there could be other reasons for
the voltage change—and any which caused
enough change would result in automatic
compensation by the projector(s) and a change in
light level.
To help prevent this, try to use controlled
electrical circuits, so that voltage fluctuations are
held to a minimum; or use circuits that provide
voltages which are either sufficiently below or
above the switch-over points. This will prevent the
automatic sensing circuits in the projectors from
36
making a change. even though there may be a
fluctuation of several volts in the supply.
In the previous examples. some specific voltages
are mentioned. The voltages on which projectors
are operated should not fall outside the ranges for
which the equipment is designed (110-130 V and
220-240 V). However, occasionally there may be
some variation in the actual voltage at which
projectors change from “boost” to “buck”
configuration. And there may be very minor
variations from one projector to another. In
general, however, the changes will occur in
approximately the center of the 110-130 V range
(perhaps 115-120 V): or in the center of the 220-
240 Y range (perhaps 227-233 V). The point at
which the actual change will occur, with either
decreasing or increasing voltage. is not completely
consistent (because of normal variations in
electronic components); nor is it easily adjustable.
CAUTION: Bypassing the projectors boost-buck
circuit is not advisable, since it may result in
overheating or insufficient power in the motor
and unacceptable variations in lamp life and
light output.
The motor used in the Model B-2AR operates
satisfactorily on either 50 or 60 Hz, and thus no
special sensing or switching is required for
frequency change. The motor runs slightly slower
on 50 Hz. Slide change time is about 1.2 seconds
on 50 Hz and about 1 second on 60 Hz. The fan-
driving pulley on the motor is slightly larger than
on the motors of most EKTAGRAPHIC Slide
Projectors, so the fan will be driven at normal
speed on 50 Hz to provide full cooling. It operates
at a little greater than normal speed on 60 Hz.

Some Questions and Answers about
the KODAK EKTAGRAPHIC Slide
Projector, Model B-2AR
Q. What are some differences between the
Model B-2 Projector and Model B-2AR
Projector?
A. The B-2 Projector has a cord compartment
while the B-2AR does not. The cord
compartment space in the Model B-2AR is filled
with electronic sensing and switching parts.
MODEL
B-2AR
Also. the motor in the Model B-2AR runs a little
faster on 60 Hz current than the motors in
domestic projectors, so there will be plenty
of cooling of the B-2AR when operated on
50 Hz also.
Q. What does the “AR” stand for?
A. “A” stands for “Automatic.” "Ris a designation
Kodak has used for equipment models made in
the U.S. and Canada but which can be used on
either 120 or 240 Y. and on either 50 or
60 Hz. |
Q. What projection lamps does the Model B-2AR
use?
A. It normally uses the same lamp as domestic
projectors—the ELH: however. the long-life
(ENH) and high-output (ENG) lamps can also
be used.
Q. Why don’t the lamps burn out when the
projector is used on high voltage?
A. An autotransformer built into the projector
reduces the voltage to the proper level for the
lamps.
Q. Wouldn't a solid state dimmer (with an SCR
or Triac) do the job with less weight and
problems?
A. Probably not. Unless a complicated circuit is
used. the electrical “spikes” and “hash” from
such devices can cause problems not found in
electrical sine waves vou get from a true
transformer.
Q. Why not use the EXTAGRAPHIC S-AV2050
Projector (described later in The Source
Book) instead?
A. The Model B-2AR can be used with domestic
parts and accessories, such as the AODAK EC
Remote Controls, the EKTAGRAPHIC
Programmable Dissolve Control, Model 2, multi-
image computer programmers, and extension
cords, etc, which will not interface with the
EKTAGRAPHIC S-AV2050 Projector. But the
automatic voltage switching capability is the
biggest reason for using the Model B-2AR. It is
a convenient projector to use in places that
provide both low and high-voltage power
sources. (These are common in a number of
countries.) In addition, there is a faster lamp
decay rate when using the Model B-2AR. (The
light from the ANSI Code EHJ lamp in the
S-AV2050 Projector decays more slowly when it
is turned off than the light produced by the
ANS] Code ELH lamps used in the Model
B-2AR.)
Q. Will the Model B-2AR work with the KODAK
EKTAGRAPHIC Programmable Dissolve
Control, Model 2, and other dissolve controls,
on either voltage range, and on either 50 or
60 Hz?
A. Yes.
Q. What happens if the Model B-2AR is
connected to voltage outside the ranges
specified for it?
A. Damage. Some of the projector components are
likely to overheat and burn out with either too
high or too low a voltage, just as with any
domestic EKTAGRAPHIC Slide Projector that is
operated on voltages outside its normal range.
Signs of excessively low or high voltage include
a chattering relay in the projector. failure of the
motor to start, or unusually bright lamp. (Of
course, as with any electrical appliance. you
must know the voltage being supplied before
using the projector.)

The Speed of Slide Change in
KODAK EKTAGRAPHIC Ill and
EKTAGRAPHIC Slide Projectors
Q.
A.
Why is slide-change “speed” of such
particular interest today?
As the art and science of multiple projection of
slide images (multi-image) continues growing,
AV professionals want to achieve more
impressive “animation” effects by more rapid
image changes.
. Is the concern about the speed of slide
change limited to multi-image presentations?
. No. A fast slide change using a single projector
means a shorter dark-screen interval between
images, and therefore, a smoother presentation.
. Do cardboard, glass, plastic, or metal mounts
affect the speed of slide change in a
projector?
. Hardly at all. A slide has to fall only 2 1.2
inches from the tray into the projector gate.
The slide mount has little practical effect on
the rate at which the slide falls.
. What effect does the projector’s drive motor,
slide registration system, and tray movement
have on the speed of slide change?
. Very little. The most important factor is the
time required to get one slide out of the
projector gate and the next slide in.
Gravitational acceleration is one of the most
important factors.
. Then gravity is the most important factor that
determines the speed at which a slide can be
changed in a Kodak slide projector?
. In combination with other factors, yes. À slide
can fall into the projector gate only as fast as
gravity permits it to fall. In addition, there must
be a control lever in the projector mechanism
that supports the weight of the slide in the tray
at the beginning of a slide change. The lever
lowers the slide into the projector gate at less
than the speed of gravitational acceleration. If
the lever dropped faster, it would leave the
bottom of the slide. In addition, it must slow
down as it comes close to the bottom of the
gate so the slide will come to a gradual stop
and will not bounce or make noise. Once the
slide is in the gate, the shutter opens and the
image is projected on the screen.
o
. How is the slide moved out of the gate?
. The procedure is reversed. The projector slide-
lift lever must move up and touch the bottom
of the slide and then raise it smoothly into the
tray. This must be done with controlled speed
because inertia would make the slide keep on
going and pop out of the tray (if the tray ring is
off) or hit the tray ring and produce an
objectionable noise. As a result, the rate of lever
slowdown must be consistent with gravitational
pull which is operating in opposition to the
inertia of the slide as it goes up into the tray.
. The up- and down-speed of the lever is
important, isn't it?
. Yes. You cant engineer the lever to go up or
down at any speed you want. The maximum
speed of the lever must take gravity into
consideration.
. Are there other considerations?
. Yes. Because of friction and air resistance
between the slide and the air around it, an
additional safety factor must be built in. The
lever must be slowed down a little more. Once
the slide is in the tray, the tray must move to
the next slide position so the lever can lower
the next slide and repeat the entire process.
The time required to move the tray depends
upon friction of the slides moving on the
bottom of the tray. This movement can be
reduced to a small fraction of a second, but it
cannot— with present technology —be made
instantaneous.
. What happens if you try to speed up the
movement?
. If you speed up the entire process, the slides hit
the tray ring and produce objectionable noise,
and slide-change reliability decreases.
In summary, adding the time required for the
slide to descend into the projector gate and come
back up to the time needed for the tray to move to
the next slide equals about *s of a second.
Q. Well, how long does it take an
A.
EKTAGRAPHIC Slide Projector to change a
slide?
About 1 second. The extra Ys of a second
provides a safety margin for reliability.

Ge neral Features
S-AV Projectors are manufactured in West Germany by
Kodak AG and imported into the United States by
Eastman Kodak Company. These projectors are provided
with international features. A built-in voltage-selector
switch allows them to be used with power supplies
from 110 to 250 V, 50 or 60 Hz, almost anywhere in
the world.
These projectors have a heavy-duty motor, and
excellent optics. They are often used for unattended,
continuous-projection applications, such as in window
displays and planetariums.
Shown at the right are dimensional line drawings for
the S-AV Projector line to assist people who need this
information in the design and construction of projection
shelves, piggyback stands, carrying cases, etc.

NOTE: When designing enclosures for these projectors,
do not obstruct air intake and exhaust areas located at
the front, left, and rear sides of the projector. Also, allow
about 2 inches (51 mm) behind and on the right side of
the projector for plug connections, and about 3 inches
(76 mm) clearance above the slide tray for tray removal.
Allow for additional space at the right of the projector
to permit opening the door for lamp change without
moving the projector.
This projector is generally similar to U.S.- and Canadian-
made FKTAGRAPHIC Slide Projectors, but there are
some important differences.
The Controls and Their Functions
Power Switch
This is an on, off rocker switch located on the back
panel of the projector.
Power Cord
The grounded, 3-wire, 11.5 foot (3.5 m) removable
power cord connects to the power receptacle at the back
of the projector. The cord provided has a standard U.S.-
Canada-type 3-connector plug. The connection to the
projector is standard so that power cords with
appropriate wall-plug connectors can be obtained in
most countries. When plugged into a grounded outlet,
the power cord provides an automatic safety ground for
the projector chassis.
Forward (Select) and Reverse Buttons
The forward (select) and reverse slide control buttons
are located on the top of the projector at the back.
When the forward button is held down, it acts as a
select bar, permitting manual tray rotation to any slide
for projection or to the zero position for tray removal.
Lamp-Change Lever
A convenient lamp-change lever located at the lower
right edge of the back panel of the projector allows the
user to quickly move a replacement projection lamp into
operating position during a show without moving the
projector or opening the lamp door. This feature
reduces the duration of the dark-screen time that
usually follows projection lamp failure. New projection
lamps can be installed later after the show at the
convenience of the user. A tilt-out bar holds two

Alternative Projection Methods
The EXTAGRAPIIC Slide Projector, Model S-AV2030
can be used in a wide range of special projection modes,
including two-projector dissolve shows and multi-image
presentations. Methods of projection using single
projectors include:
® Continuous Projection With 81 Slides: Before
installing the slide tray, insert an additional slide in
the gate. This utilizes the zero compartment of the
tray for continuous projection. For automatic slide
changing, use a continuous-loop tape recorded for
continuous projection.
Uninterrupted Multi-Tray Projection (Using One
Projector and Two Trays): This method of projection
is useful for showing many slides without a break in
the show when changing trays. Before starting the
show, place slide number 81 in the gate and set slide
tray No. 1 to slide number 1. Change the slide tray
while slide No. 81 is being projected. This slide then
returns to the zero compartment of tray No. 2.
Automatic Slide Tray Zero Reset: The zero-reset
switch selects the direction in which the tray runs to
zero. If a slide set has less than 40 slides, let the tray
run toward zero by pushing the switch up. During
slide tray return, an automatic shutter cuts off the
projection light but moves out of the light path again
on reaching the zero position. (The zero-reset signal is
triggered by an empty slide slot in the tray.)
Flashing of Images: Images can be made more
impressive or interesting by flashing them. The flash is
controlled via the 12-pole receptacle on the side of the
projector. (Details are provided in the instruction
manual packed with the projector.)
Long-Run Applications
For information on long-run applications, refer to page
19 under the EXTAGRAPHIC III E Projector.
Operating the Projector
General
Operate the projector in basically the same manner as
domestic EKTAGRAPIIIC Slide Projectors, allowing for
the differences in controls and their use. Significant
differences (described in detail in the instruction
manual packed with the S-AV Projector) include:
® Projection lamp alignment for optimum illumination.
® Checking that the proper condenser is in the best
position for the slide type and lens (focal length)
being used.
NOTE: The slide-cycle time (the time required for the
EKTAGRAPHIC S-AV2030 Projector to change a slide)
is slightly longer than for domestic EKTAGRAPHIC
Slide Projectors, EKTAGRAPHIC 111 Projectors, and
the EKTAGRAPHIC Slide Projector, Model S-AV2050,
discussed later. The slide-cycle time for the S-AV2030
Projector is about 1.4 seconds when operating on
60 Hz power and 1.7 seconds when using 50 Hz
power.
Emergency Tray Removal
In case of operational failure caused by a bent slide, the
tray can be removed from the projector by pushing
aside and holding the slide tray latch while lifting off
the tray.
Shutdown
You should adopt a standard shutdown procedure after
each presentation, similar to the one that follows. This
approach will not only help you to be ready for the next
show, but will help provide proper care for the
projector.
* With projector power on, rotate the tray to the zero
position by pressing and holding down the slide-
forward button.
e Remove the slide tray.
* Turn off all power to the projector with the power
switch.
45
If the projector will be moved before the next show:
e Retract the elevation legs.
® [f desired, remove the projection lens.
® Unplug the remote control unit (or dissolve control if
used).
® Disconnect the power cord from the power source and
from the projector; place the projector in a suitable
container or travel case for maximum protection.
* Before you attempt any maintenance or cleaning of
the projector, be sure it is cool and the power cord
disconnected from the power outlet. Also remove the
slide tray and remote control or dissolve control.
Projector Maintenance
Switching the Projection Lamp
This projector has two low-voltage tungsten-halogen
lamps of 24 V, 250 W available, ANSI Code EHJ. The
lamps are mounted on a rapid lamp changer, If the lamp
in use should fail, the spare lamp is immediately ready.
If the lamp fails to light when the projector is turned
on, but the fan operates, the lamp-control lever is in the
wrong position or the lamp is burned out. To change
the lamp over, move the rapid lamp changer at the rear
of the projector to the appropriate position.

Detailed lamp centering instructions for the various
lenses appear in the “User's Instruction Manual” packed
with the projector.
Cleaning the Projection Lens
Remove the projection lens. Blow off any loose grit.
Then wipe both glass surfaces with KODAK Lens
Cleaning Paper, or with a clean cloth moistened with a
single drop of KODAK Lens Cleaner. (Equivalent
products are available and may be used. if desired.)
Fingerprints reduce the brightness and clarity of screen
images. but a little dust does not.
FROJFCTION I ENS
The Condenser Optics
The condenser system in the projector is designed to
match the projection lens in use. If the condenser lens
is in the wrong position, or if the wrong condenser lens
is being used, the projected image may not be as bright
as it could be. Details about the condenser system are
provided in the “User's Instruction Manual” supplied
wIth the projector.
Allowing Proper Ventilation
Refer to the information on the EKTAGRAPHIC 111 E
Projector for instructions on proper projector
ventilation (page 22).
Automatic Thermal Safety Switch
The EKTAGRAPHIC Shde Projector, Model S-AV2030, is
fitted with an automatic thermal safety switch, which
turns off the projector if it overheats because of a lack
of cooling air or Jamming of the slide-change
mechanism. Once the projector has cooled, it switches
on again automatically.
Running the fan to cool the projector after the lamp
is turned off 15 not necessary nor recommended. If the
tray is to be removed, it should be returned to zero
hefore shutting off the projector.
Dirt and dust cause deterioration of the projector
lubricant and can eventually cause machine malfunction.
We recommend that the projector be serviced after 500
hours of operation. For projectors used in very dusty
locations (such as in fairs or exhibitions), more frequent
servicing may be advisable. More detailed instructions
for cleaning the optics, changing and aligning
projection lamps, and other user-performed services are
included in the “User's Instruction Manual” packed with
the projector. Service requiring disassembly should be
performed by a qualified service technician, such as
those at Kodak's Equipment Service Center in
Rochester, NY. Kodak installations which can provide
information or service in most countries of the world

The Model S-AV2050 Slide Projector is also made by
Kodak AG in Stuttgart, West Germany, and has most of
the features, functions, and maintenance requirements
of the Model S-AV2030. The Model S-AV2050 has the
advantage of a shorter slide-cycling time of about 1
second on 60 Hz current and 1.2 seconds on 50 Hz
current. It also has a projection-lens mount that accepts
KODAK Projektion RETINAR lenses (distributed by
Kodak AG) as well as the less expensive KODAK
Projection EKTAGRAPHIC FF and FKTANAR Lenses
familiar in the U.S.
NOTE: The remote focus lever on the KODAK
EKTAGRAPHIC S-AV Remote Control shown in the next
column can be used to remotely focus the S-AV2050
Projector with either type of lens installed in the
projector—a KODAK Projektion RETINAR Lens or an
American-made KODAK Projection EXTAGRAPHIC FF
or EXTANAR Lens.
The Model S-AV2050 Projector also has a constant
lamp-brightness setting that 1s equivalent to high
brightness on the Model S-AV2030. The Model S-
AV2050 does not have the built-in automatic return to
zero feature but it does have a built-in zero-position
switch that can be used by an external control to
provide automatic tray return to the zero position.

The EKTAGRAPHIC Slide Projector,
Model S-AV2050, can be used with
a KODAK EKTAGRAPHIC S-AV
Remote Control.
The Controls and Their Functions
The controls and functions of the Model S-AV2050 are
generally the same as described for the Model S-AV2030,
with the following exceptions:
® Lamp Setting: The Model S-AV2050 has only a single
lamp setting equivalent to the “full power” brightness
setting on the Model S-AV2030. (Instructions for
centering the lamp appear in the “User's Instruction
Manual” packed with the projector. A spare lamp
holder for a third lamp is provided on the inside of the
lamp door.)
* Focus: Focusing of slides is accomplished in one of
two ways depending on the type of KODAK Projection
Lens used. If you have a RETINAR Lens distributed by
Kodak AG, focus the lens itself by turning the barrel
along the spiral grooves (in the same manner as the
S-AV2030 Projector). If you have an EXTAGRAPHIC
FF or EXTANAR C Lens (familiar in the U.S.), set the
image focus with the focus knob on the projector. If
KODAK EKTAGRAPHIC Slide
Projector, Model S-AV2030
you are using a KODAK EKTAGRAPHIC FF Zoom
Lens, 100 to 150 mm / 3.5, made in the U.S, first
adjust image size by turning the lens barrel, and then
refocus the image. If you are using a German-made
VARIO-RETINAR zoom lens, adjust image size by
pulling the front of the lens out or push it in, and
then focus by turning the lens.
Shorter Slide-Cycling Time: The slide-cycling time
of the S-AV2050 Projector has been reduced from
1.5 seconds to about 1 second on 60 Hz current and
1.2 seconds on 50 Hz current. The result is a reduced
dark-screen interval for single-projector programs. For
multi-image programs, faster slide advancing 1s
possible. The 0.5 second faster slide-cycling time with
the S-AV2050 Projector means that intervals between
slide changes can be programmed to be even shorter.
For this reason, slide presentations programmed using
the S-AV2050 Projector (using slide change times
faster than 1.5 seconds) should not Бе projected with
S-AV2030 Projectors without a thorough rehearsal.
(Reprogramming of some image transitions may be
necessary). After two slide changes in quick succession
with S-AV2030 Projectors, the slide change may not be
completed during the dark time of the lamp and there
may be a white “flash” on the screen. In addition, if
one S-AV2030 Projector continues to receive slide-
advance commands at intervals of less than 1.5
seconds, some of the advance signals will he ignored
and the projectors will fall out of synchronization. Of
course, programs made using the S-AV2030 Projector
can be run on the S-AV2050 Projector without
difficulty.

EKTAGRAPHIC S-AV2050 Slide
Projector
The time required for the 24 VV EHJ lamp to go up
from 10 percent light output to 90 percent light
output (incandescence) is 310 ms. and the time
required from 100-percent light output to 10-
percent light output (nigrescence) is 225 ms.
Some points of the lamp light decay curves are

Some Questions and Answers About
the KODAK EKTAGRAPHIC Slide
Projector, Model S-AV2050
Q. What does “S-AV20507 mean?
A. “S” stands for Stuttgart (Germany), where
Kodak makes the projectors. “AV” stands for
audiovisual, and “2050” is the model
designation.
Q. Why the name “EXTAGRAPHIC S-AV2050”
rather than CAROUSEL S-AV2050 Projector?
A. Mostly because the projector is closer to the
US.-Canadian concept of EKTAGRAPHIC Slide
Projectors than to domestic CAROUSEL*
Projectors. The projector has
e Slide registration for improved
superimposition of images.
e EMI (electromagnetic interference) supression.
® Heavy-duty clutch with arc supression.
¢ Three-wire grounding power cord.
e Gray casing for easy identification as a
professional AV projector. Its primary purpose,
outside the U.S. and Canada, is for audiovisual
and professional use, not for home or amateur
use. and is sold in the U.S. and Canada by
dealers in Kodak AV products.
Q. Why do people want to buy the
EKTAGRAPHIC S-AV2050 Projector?
A. A number of very good reasons: it can operate
on four different voltage ranges for use in
almost any country; the lamp is easily switched
during a show and there is space for a spare; it
provides positive, repeatable, horizontal and
vertical slide registration; built-in arc
suppression controls EMI (electromagnetic
interference) of the focus motor; the carrying
handle is retractable: there are different
condenser positions for more efficient coverage
of super slides and 24 x 36 mm slides; there are
a variety of focal-length lenses available; the
projector uses conventional lenses (non-
retrofocus) as short as 28 mm in focal length
without vignetting 24 x 36 mm transparencies;
there is a large receptacle on the side for access
to many internal circuits; the slide-cycle time is
improved over earlier S-AV projectors. etc.
Q. Those sound like real advantages; why would
| buy another EKTAGRAPHIC Slide Projector
model?
A. Because some other model might fit your needs
better. Here are some of the features of the
EKTAGRAPHIC Slide Projector models or
EKTAGRAPHIC 111 Projector models that are
not available in the S-AV2050: built-in
automatic timer: autofocus; autofocus defeat
switch: high and low lamp settings; special-
applications receptacle; convenient select bar
tray removal with power off; use of 140 slide
trays: prefocused lamps; faster lamp flashing;
automatic adjustment to proper voltage setting
(Model B-2AR); built-in miniprojection screen
for editing and previewing: two tie-down points
for projector security; convenient power-cord
wrap; standby light; reading light: illuminated
control panel; less weight than the Model
S-AV2050; many U.S. and Canadian accessories
available, and so on.
. What about all the other accessories available
in Europe and elsewhere for the S-AV2050?
. Kodak can provide information on sources of
supply for these accessories in the U.S., but we
have no plans to import accessories ourselves at
present. (You can send your inquiry to Eastman
Kodak Company, Department 625, 343 State
Street, Rochester, NY 14650.) A number of
accessories are already available from other
sources in the U.S. These include dissolve
controls, timers, lenses, etc.
. Do these lenses have shorter or longer focal
lengths than those on imports?
. Both. In addition, D.O. Industries, 317 East
Chestnut Street, East Rochester, NY 14445,
offers some curved-field lenses for the S-AV
models (the lenses imported by Kodak are all
flat-field type).
. Why does the $-AV2050 Slide Projector weigh
so much (17 pounds without tray, power cord,
or lens)?
. Because it contains a husky, multicap
transformer—the reason that it can operate on
such a variety of voltages. As a point of
reference, the FEKTAGRAPHIC Slide Projector,
Model AF-2, weighs 10 pounds (4.6 kg), and the
EKTAGRAPHIC II E Projector weighs 12
pounds (5.4 kg).
. Can the $-AV2050 Projector be controlled by
AV cassette tape recorders or KODAK
ER rAGRAPHIC AudioViewers with built-in
synchronizers?
. Yes. All that's needed 1s an adapter or new plug
on the control cord. In fact, any AY tape player
(with a suitable adapter) that produces a circuit
closure of approximately 500 milliseconds can
be used to provide automatic slide-advance
signals.
. Is the remote-control circuit the same as in
domestic projectors?
. It is similar, but not the same. The voltage is
about the same, but it uses direct current rather
than alternating current.
. Do all KODAK Slide Trays work well with the
$-AV2050 Projector?
. Trays that were manufactured with a plastic
latch (instead of metal) used to cause minor
problems. These have been resolved, however,
and all U.S.-made Kodak trays (except the 140
type, which is not recommended for use with
this projector) now work fine.
. Are warranty and repair services available
from Kodak?
. Yes; from Kodak's Equipment Service Center in
Rochester, New York.
