ELECTROSTATIC DISCHARGE
CAUTION
This equipment includes parts and assemblies sensitive to damage from electrostatic discharge. Use caution
to prevent damage during all service procedures.
Overview
Electrostatic discharge (ESD) is a primary source of
-
-
-
product downtime
lost productivity
costly repair.
While we cannot feel a static charge of less than 3,500 volts, as few as 30 volts can damage or destroy essential
components in the electronic equipment. As technology advances, these components will be even more
vulnerable to ESD destruction.
Therefore, to maintain and increase productivity and profitability, you must observe ESD guidelines.
Effective ESD control requires the following things.
Awareness
Everyone in your organization should be aware of ESD because partial ESD control is no ESD control at all.
Everyone needs to remember that:
-
-
-
ESD is a primary source of equipment failures and intermittent malfunctions.
ESD affects productivity and profitability.
ESD can be controlled.
Action
Everyone from senior management to the evening security crew, must observe ESD guidelines.
-
-
If you repair and maintain electronic equipment, always wear grounding straps and work
at ESD protected sites.
If you work around electronic equipment, keep static generators like plastic trash bags
away from sensitive components.
-
-
Observe ESD guidelines everyday. (See the following sections for special tips).
Remember, effective ESD control is everyone’s responsibility:

SM 2547-1
Every Day
1. Keep trash away from static-sensitive equipment. Plastic materials, such as trash can liners and plastic
foam cups, generate the static electricity that damages or destroys electronic components.
2. Look at the label. Static-sensitive components are marked with bright graphic labels. Follow the label
directions.
3. Spray the carpet. ESD that is generated when you walk over carpet is a major cause of component
destruction. In some cases, especially in low-humidity environments, you may need to periodically spray
carpets with an anti-static spray that is available at local stores.
During Maintenance and Repair
1. Wear a grounding strap when you work with static-sensitive components. Always make certain that the
clip is attached to a properly grounded, unpainted surface.
2. Use a portable grounding mat if you cannot repair components at an ESD-protected workstation.
(Kodak’s Customer Equipment Services Division can help you in set up ESD-protected workstations.)
3 . Use protective packaging when you transport components from one area to another. Transparent
antistatic bags, available from a variety of manufacturers, shield the components from further damage.

Safety Precaution
1. Do not operate or repair the projector without proper accessories. Add all COVERS before use to
prevent mechanical hazards and electrical shock.
2. Before operating the projector, check the VOLTAGE SELECTOR. Make sure that the correct line voltage
is selected.
3. Do not use a damaged POWER CORD. The damaged CORD can cause malfunctions and current
leakage or electrical shock.
4. If there is any abnormal noise, smell or smoke during operation, deenergize the projector immediately
and contact authorized personal for support.
5. Do not operate the projector in unsafe locations such as outdoors or in wet places. Do not allow liquids,
gaseous or solid-state materials to enter the projector.
6. When doing electrical measurements, use an isolation transformer or a leakage current detector in the
power line to avoid an electrical shock.
7. Use only original parts from the Parts List to repair the projector.
8. Make sure that the requirements of UL 122 - Splices and Connection - paragraph 13.10 and EN 60 950,
section 4.39 are observed. When replacing AC primary components, such as wires, sockets or capacitors ,
wrap the ends of the wire completely around the terminal before soldering.

The adapter of this English company is only designed to use traditional AV cassette recorders. Cue pulses
recorded on the tape trigger the interface unit to generate digital commands to advance the EKTAPRO Projector.
It is an interesting feature that the adapter works either by plugging directly into the remote socket or works
remotely by additional use of the EKTAPRO IR Receiver. In this case the system can simultaneously used with
both the EKTAPRO IR Transmitter and the adapter. The adapter is powered by a 9 volt A PP3 battery.
The illustration (figure 2-20) shows both possibilities to run the Projectors.

IR-USE.
The advantage is that the Adapter and Projector can be separated. In addition, the use of the
EKTAPRO Remote Transmitter is possible without disconnecting the Adapter.
CABLE USE
If no IR receiver is available the Adapter can be plugged with the fixed installed cable to the remote socket.

SLIDE SYNCHRONIZER ADAPTER by KODAK AUSTRALIA
Kodak Australia offers an own solution of a slide synchronizer adapter. This unit is built in the IR Receiver
housing and is therefor directly to be plugged onto the remote socket. A 6pin socket is built into the housing.
The system supports most of traditional AV cassette recorders. The S-AV cable remote can also be used with
the possibility to give transport commands and to focus. Speaker desk (lecterns) installations can be fully used.
The system is able to switch the Projector into the standby mode (press forward and reverse button
simultaneously) or run to the Projector to the zero position (press and hold down forward and reverse button).
NOTE
The S-AV Timer does not work on this adapter!

ADAPTERS by MAYER & ZELLER
The Swiss company Mayer & Zeller offers a 1000 Hz adapter which comes along in a small black plastic box
with a standard 6pin female receptacle and an integrated cable with the new 8pin male connector for the
EKTAPRO Projectors.
The adapter offers the possibility either to connect a traditional AV cassette recorder to advance the Projector
or
to connect the standard cable S-AV remote control or to use the cable already installed in the speakers desks.
The adapter is also offered in a special version which also enables the control of the focus via the remote control
(or speakers desks).

NOTE
The S-AV Timer cannot be used because of the lack of a support voltage . But Mayer & Zeller offers a
special Timer for controlling the EKTAPRO Projectors. The timer is built into the EKTAPRO Cable Remote
Control. This a quite sophisticated solution and an interesting offer for those who intend buying a cable
remote.

Tray Motion
The STEPPER MOTOR is responsible for the slide tray movement. To move the tray one slide forward or reverse
47 steps are necessary in case a tray for 80 slides is used and 27 steps in case a tray for 140 slides is used.
The tray movement is controlled by the TRAY MOTION CONTROL PCB. This PCB contains two optical sensors,
one for the code wheel and one for the Zero Position Gear.
This PCB is sending following feedback signals to the MICROCONTROLLER:
-
-
-
Tray motion direction (forward or reverse)
One pulse for each step of the STEPPER MOTOR
Tray zero-position signal in case the tray is in the zero position
If the STEPPER MOTOR moves one step, a pulse will be send back from the TRY MOTION PCB to the
MICROCONTROLLER after the step is done.
If these pulses are missing, the MICROCONTROLLER assumes that the tray is not able move. The transport
stops immediately. A failure code is written into memory, the projector do not operate, the power LED is blinking
The projector must be deenergized. The jam must be cleared. As soon as the problem is solved, the projector
should operate after switching on again.

LAMP Control
a) Dual LAMP Operation
All Models are equipped with a DUAL LAMP MODULE (Extra Bright).
The POWER REGULATION PCB on all Models contains a LAMP current circuit that can detect if the active
LAMP is on, indicated by a LED on the BACK PANEL.
If a LAMP fails, the MICROCONTROLLER receives the LAMP_CURR signal from the POWER REGULATION
PCB. It activates the MIRROR MOTOR and moves the MIRROR to the second LAMP position. Then the relay
K1 is energized and second LAMP is energized. The MICROCONTROLLER also energizes the LED for the
second LAMP. The LED’s are located on the BACK PANEL.
The Models 4020 - 9020 and 9020/CINE have a memory. This memory is storing the the current used lamp as
long as the lamp is defective. That means the mirror of the DUAL LAMP MODULE do not change his position
after a new lamp is inserted. This function can be disabled (see page 2-3).
The characteristic of the lamp curve is no longer generated by a PLL circuit on the MASTERBOARD. Up to
now it is stored in the Software LAMP Control memory and the TRIAC will be triggered from the
MICROCONTROLLER.

b) LAMP setting
Models 4020 - 9020 and 9020/CINE:
a) Through the LAMP SWITCH or P-Bus
The settings of the LAMP are change by using the LAMP dimming function through the TRIAC
DISSOLVE LOGIC. The phase cut position for LOW is 75% of HIGH .
The LAMP supply voltage is 91 VAC only.
Resulting LAMP voltages:
Standard: 82V RMS
Economy : 72V RMS
b) Via accessory slot
External units that are connected to the accessory slot cannot use the Standard/Economy LAMP
setting with phase cut. Therefore, the LAMP supply voltage is switched with the ECONOMY
SIGNAL and a relay to 82 VAC.
The functions of the STANDBY and Standard/Economy Buttons are disabled.
c) LAMP Protection
In the LAMP RETURN LINE on the POWER REGULATION PCB there is a small circuit that detects the actual
LAMP current.
LAMPS can explode when they reach the end of their life. The melting filament can create a short circuit with a
high current.
The high current is detected, and the LAMP is deenergized immediately by the TRIAC.
This procedure prevents the LAMP from exploding, and protects the TRIAC.
d) LAMP Voltage Control
All Models are equipped with a LAMP voltage regulation so that the LAMP voltage does not follow line voltage
fluctuation. The 5V AC outlet of the POWER REGULATION PCB i used to create the VAC_Value signal on the
MASTER PCB. This signal is fed to the MICROCONTROLLER (MC). The MC then selects a phase cut position
of the LAMP voltage which results in a reasonable constant LAMP voltage. This function is disabled if an
accessory is connected to the accessory slot. In this case the LAMP operates with 82 VAC.

The zero-cross circuit creates an impulse whenever the LAMP
voltage crosses the zero line (LAMP voltage close to zero).
See figure b.
a) Lamp Voltage
Therefore, every 10ms for 50Hz or 8,3ms for 60Hz a signal
change occurs. This signal is sent to the DISSOLVE LOGIC on
the MASTER PCB. The DISSOLVE LOGIC generates a
clocksignal with 4096 pulses for the length of half a sine wave.
This clock signal is triggered by the zero-cross signal.
See figure c.
Through the DATA SIGNAL, the MICROCONTROLLER delivers
a value between 3 and 3700 to the DISSOLVE LOGIC. Values
of 0 to 4096 are possible, but these valves would cause
false phase cut positions because the zero-cross signal does not
detect zero on the sine wave.
b) Zero-Cross Signal
At the next zero-cross of the LAMP voltage, the DISSOLVE
LOGIC reads the value in the MICROCONTROLLER. This value
can range from 0 to 1000, and is counted by internally generated
clock signal. The clock signal sends the TRIAC TRIGGER signal
to the TRIAC CONTROL on the POWER CONTROL PCB.
c) Internal Counter Clock Signal
4096 Pulses
4096 Pulses
The TRIAC is energized and the LAMP is energized for the rest
of that half sine wave.
If the MICROCONTROLLER sends a new value, the next half
would have a different phase cut position. If the value is not
changed, the cut position leaves unchanged.
d) Example
The LAMP dissolve function operates between zero and high
with an accessory in the accessory slot or with RS232. High or
low on the LAMP is controlled by the BRIGHTNESS SWITCH.
1000

e) Trigger Impuls
The dissolve range of zero to full brightness is divided into 1000
steps. These steps can be used to create a linear LAMP
brightness change.
A lookup table is used in the MICROCONTROLLER software.
This table contains the corresponding phase cut value for each
one of the 1000 steps for a linear brightness setting.

Focus
There are different possibilities to get a crisp and clear focused image on the screen.
1. Use the FOCUS KNOB. In this case the LENS will be moved inside the LENS CARRIER, while the LENS
CARRIER still keeps his position.
2. Use the FOCUSING BUTTONS either on the KEYBOARD of the PROJECTOR or on the REMOTE
CONTROL. In this case the LENS and the LENS CARRIER are moving together. The focus range
is limited, and depend on the ECCENTRIC of the FOCUS MOTOR (approx. 8mm / 0.3 in.).

AUTO FOCUS
The AUTO FOCUS feature is installed in the EKTAPRO Model 5020,9020 and 9020/CINE.
A “low” FOCUS EXT signal from the MICROCONTROLLER enables the AUTO FOCUS PCB while a “high” signal
disables the AUTO FOCUS to ensure a sharpness correction for the projected slide. If a manual sharpness
correction was necessary the AUTO FOCUS MOTOR moves back to its primary position after the next slide
change. The AUTO FOCUS MOTOR is running until both receivers has the same light input. The FOCUS
MOTOR stops at the time the light input on both Photo transistors is equal. The direction for the focus movement
is defined by either receiver port 1 or port 2.
An electronic circuit will determine the operating voltage for the FOCUS MOTOR (running forwards or backwards)
to ensure to have the same speed in both directions. This regulation is necessary because the LENS CARRIER
is basic loaded with a spring in one direction.
To ensure that the AUTO FOCUS function works properly it is very important to use the same kind of slide
frames. Mixing up glass slides with other slides will bring the projected image out of focus because there is only
one reference point for the lens position to get a sharp and clear projected image on the screen.
If glassless slide frames are in use, it could be, that the borders of the projected image are out of focus.
It depends on the IR-Beam which is only sensing the center of the slide.

P-BUS
All the Models are equipped with the P-Bus feature.
The Models 4020 and 5020 has only an Input Bus, Models 7020 and 9020 and 9020/CINE an IN/OUT Bus.
The P-Bus (Presentation Bus) is a serial asynchronous data transmission interface which uses the RS 232 /
V.24/ V.28 standard. This type of interface is used with Personal Computers for external communication.
figure 3-14
The purpose of the bus is to enable computer controlled projection with one or more slide projectors. Up to 16
different EKTAPRO 7020 or 9020 and 9020/CINE projectors can be addressed separately if they are connected
through a daisy chain configuration. The projector addresses can be selected on the PROJECTORS ADDRESS
SELECTOR SWITCH which is located above the P-Bus connectors.
The P-Bus interface configuration is initially set at:
-
-
-
-
-
1 Start bit
8 Data bit
1 Stop bit
9600 Baud rate
No Parity
The signal levels must be equal to the RS232 specifications.
The signal lines are only “Transmit Data” and “Receive Data”. Bi-directional lines are not used.
The projector can be controlled by other control signals beside the P-Bus Interface. Details can be found in a
special marketing publication.
The P-Bus is also used as Service Interface for the Diagnostic Software.

Command Structure
The Command Structure is binary coded with three consecutive 8-bit bytes. Synchronization is achieved by a
break in the transmission of more than three byte times. The first five bit of each command specifies the address
of the selected projector.
The 16 hardware addresses are 0-F (hex).
The address 1F (hex) is a global address that all connected projectors will accept. Several projectors can be
combined in a group by assigning them a special group address of 10 - 19 hex with a software command. Note,
global or group addresses are separate from the position that is selected on the address switch.
Three 8-bit bytes:

Because of the microprocessor, the REMOTE
CONTROL also works with digital signals on the TTL level.
RANDOM ACCESS is also available through a REMOTE CONTROL receptacle.
The data is sent parallel as a 5 bit code from the CABLE REMOTE or the IR RECEIVER to the projector
(Keyboard PCB) with an interrupt signal.
The example shows the binary code
10000.The code 10000 is for FORWARD.
When a button on the REMOTE CONTROL
is pressed, the INT signal is low with a
maximum value of 1 µ s. Then it becomes
high again. After that the data transmission
begins.

While the focus and tray motion signal consist of only one 5 bit data record. The slide position values are always
sent as three successive 5 bit data.

Mirror Position
In the Service Software TL-4575 there is an option in the menu “Lamp toggle” to check the MIRROR FUNCTION
and change the “lamp on” option. For the correct function in the projector, set the MIRROR to position 1 when
Lamp 1 is active, or reset the projector.
If the MIRROR does not move by the software command, check the resistance of the MIRROR DC MOTOR
(see figure) and measure the 34 VDC voltage on the MASTER PCB if necessary.
Brightness Test
Use the option “Adjust Brightness” from the Service Software TL-4575 to dim the PROJECTOR LAMP. There is
a range from “0" (dark) to ”1000" (bright), in steps of 10 units. With the “Reset” command in the main menu the
original brightness can be reset.

7. MAINTENANCE
Maintenance Intervals
After about 1 500 running hours or 500 000 SLIDE LIFTER cycles at a room temperature of 0 - 40°C (32 - 104°F)
we recommend maintenance by an authorized Kodak Service.
When the projector is operated in a dusty environment or in an enclosed area, maintenance should be done
every 1000 operating hours or less, depending on the quantity of dust.
When operating in an enclosed area, supply the necessary air and exhaust. If needed, the enclosure should
have
an additional fan.
Maintenance Procedure
Open the projector. Clean with a dust cleaning device.
The following structural components should be dismounted, cleaned, if necessary parts replaced, lubricated and
assembled.
