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:

Kodak AG, Stuttgart 1-1 03/98

Service Manual 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.

SM 2547-1 Service Manual

Safety Check

NOTE

Check the area around the repaired location.

Make sure that parts and wires have been returned to the correct positions.

Completely assemble the projector before doing an electrical safety test.

The safety tests:

Ground Continuity Test Insulation Resistance Test Equivalent Leakage Current Test

Use a safety tester that measures all 3 tests at one time. Such a test device would be a Mini Tester 0701 N (Manufacturer:Gossen, Germany) or an equivalent device.

Details for safety standards can be found in the regulations:

IEC 380, 435, 950, UL 478, 1012.

Prerequisites for measurements:

- The projector is energized

- FUSE with VOLTAGE SELECTOR insert

- COVERS in place

- LAMP MODULE installed

Test values for Mini Tester 0701N

- Ground Continuity Test .......< 300 mOHM

- Insulation Resistance Test .......< = 0,5 OHM

- Equivalent Leakage Current .......< = 7 mA

Interfaces

Models 7020 and 9020 have an accessory slot. The 7/12pin module from Kodak is safety tested, and has approval from VDE and other institutions. If an OEM module is installed, inform the customer:

- the OEM is responsible for the safety and function of the module.

- the module is not part of the repair order.

- the specifications and safety warnings for the accessory in the slot are found in the “Operator’s Manual”.

OEM ACCESSORIES

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.

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 s tored in the Software LAMP C ontro l 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.

03/98 3-12 Kodak AG, Stuttgart

SM 2547-1 Service Manual

e) Lamp Dimming

The LAMP DIMMING FUNCTION is installed in Model 4020 - 9020. It is used for dissolving for Economy and Standard LAMP settings. The main devices for dimming are the TRIAC, TRIAC CONTROL and Zero_Cross circuit on the POWER REGULATION PCB, the dissolve logic and the MICROCONTROLLER (MC) on the MASTER PCB.

The TRIAC FUNCTION is controlled by the MICROCONTROLLER and its software, it works according to phase cut principals.

a) Lamp Voltage

b) Zero-Cross Signal

c) Internal Counter Clock Signal

4096 Pulses

The zero-cross circuit creates an impulse whenever the LAMP voltage crosses the zero line (LAMP voltage close to zero). Seefigureb.

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. Seefigurec.

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.

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.

The TRIAC is energized and the LAMP is energized for the rest of that half sine wave.

d) Example

1000

e) Trigger Impuls

d) Actual Lamp Voltage

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.

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.

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.).

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.

Kodak AG, Stuttgart 3-17 03/98

Service Manual SM 2547-1

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:

AAAAA MM 1 CCCC XXXD XXXXXXXD

1. Byte 2. Byte 3. Byte

AAAAA address of projector MM selects command mode CCCC commands depending on selected mode XXXX XXXX XXX commands or information depending on selected mode

An example of command modes is:

- parameter mode 00

- set/reset mode 01

- direct mode 10

- status request mode 11 In this mode, the projector returns (10 bit) data. This mode can be used for diagnostics purposes.

Details can be obtained from special marketing literature.

Accessory slot

This slot was designed for EKTAPRO Models 7020, 9020 and 9020/CINE to receive certain professional dissolve units. The 12/7 PIN ADAPTER is a PCB with:

• an “Intern/Extern” switch for a check. Intern means “Lamp on” and Extern means

“Projector is controlled by the dissolve unit”.

• connectors to connect the ADAPTER to the projector, and an ADAPTER CABLE for

different dissolve units. The ADAPTER CABLE has a 25 PIN SUB-D connector to connect the PCB ADAPTER and a combination socket for 12 and 7 PINS.

Accessories that allow the EKTAPRO projectors to communicate with older dissolve equipment are available for the 12/7 PIN sockets.

The slot contains an Inter IC Communication Interface (I 7/12 PIN Adapter. Typical I

C functions are not available.

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.

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.
