1-3 DESCRIPTION OF THE SYSTEM
System is composed of two main sub assemblies:
- MAIN UNIT : Laser Console,
- LASER HEAD : Slit Lamp.
MAIN UNIT is a metal enclosure containing all of electronics sub units.
On the top of it, there is SLIT LAMP which holds LASER HEAD. MAIN
UNIT and LASER HEAD are connected to each other with two cables :
SIGNAL CABLE (CABLE1) and HIGH VOLTAGE CABLE.
1-3-1MAIN UNIT
MAIN UNIT is a metal enclosure containing all of electronics sub units:
- MAIN POWER SUPPLY / SWITCH / FUSE UNIT,
- MAIN DC POWER SUPPLY,
- AUXILIARY BOARD,
- INTERFACE BOARD,
- CPU BOARD,
- HIGH VOLTAGE CAPACITOR BOARD,
- HIGH VOLTAGE POWER SUPPLY BOARD,
- DISPLAY / KEYBOARD UNIT,
- BACK PANEL CONNECTORS.
1-3-1-1 MAIN POWER SUPPLY / SWITCH / FUSE UNIT
There are two separate fuses : one for Line and other for Neutral :
Fuses are 4AT/250V.
1-3-1-2 MAIN POWER SUPPLY (12V or 24V)
Input is : 85 to 264 VAC, 47 to 63 Hz with maximum input current of
1,2A.
Output is 12VDC or 24VDC and it can with covered enclosure deliver
up to 40W.

SERVICE MANUAL
Rev.05/2005 P - 11
1-3-1-3 AUXILIARY BOARD
AUXILIARY BOARD distributes the electrical power to all sub-units and
control the front panel.
It is connected to MAIN POWER SUPPLY.
System can be switched ON again only, if the push button is rotated to
ON position. There are two options to turn ON the SLIT LAMP :
- first if user only wants to use SLIT LAMP without turning on the laser:
SLIT LAMP can be turned ON by pressing illuminated green SLIT LAMP
SWITCH. When the green light is ON, the slit lamp is lighted.
- second if user wants to use SLIT LAMP together with the laser : he
turns ON KEY SWITCH also the SLIT LAMP is lighted.
SLIT LAMP is connected to auxiliary board on the back panel LASER
CONSOLE.
The joystick pulse button and the lamp are controlled by this board.
1-3-1-4 INTERFACE BOARD
The INTERFACE Board (optocoupler interface) converts and distributes
electric power to other boards and laser head.
Its main functions are :
- power regulation : 5V voltage regulator (display),
12V voltage regulator (aiming beam).
- galvanic isolation : DC/DC power converter.
- digital and analog optocouplers isolation : computer signals.
- hardware control : - footswitch,
- high voltage,
- energy meter,
- shutter position,
- computer watch-dog.
- drivers for ENERGY OPTIONAL DISPLAY.
- speaker control.
- number of laser pulses selection and controlling of high voltage
power supply are on this board.

Rev.05/2005
P - 12
1-3-1-5 CPU BOARD
CPU BOARD is connected to INTERFACE BOARD via two connectors :
- one connector feeds all the digital and analog signals
- the other connector is for Computer power supply.
The CPU Board is the heart of the system :
- control of the display and front panel functions,
- control the High Voltage Capacitor Board via the interface board,
- control the laser head via the interface board.
1-3-1-6 HIGH VOLTAGE CAPACITOR BOARD
HIGH VOLTAGE CAPACITOR BOARD is connected to INTERFACE
BOARD.
The flash lamp of the laser head is supplied and controlled by this
board.
The high voltage is checked by the CPU Board (safety detection).
1-3-1-7 DISPLAY / KEYBOARD
DISPLAY / KEYBOARD unit is connected directly to Computer board.
Power for the back-light LED is fed from Interface board (5V).
Computer also controls via Interface two front panel LED diodes (green
for Stand-by and yellow for Ready) which are above STAND-BY /
READY button.
There are three keys on the front panel :
- PULSE SELECT BUTTON,
- COUNTER RESET BUTTON,
- STAND-BY / READY BUTTON.
1-3-1-8 BACK PANEL CONNECTORS
BACK PANEL CONNECTORS are :
- Main input,
- Interlock,
- Slit lamp,
- Option,
- Energy display,
- High voltage connector for laser head,
- Signal connector for laser head,
- GND terminal.

SERVICE MANUAL
Rev.05/2005 P - 13
1-3-2LASER HEAD
LASER HEAD is located on the Slit lamp.
It is connected to MAIN UNIT via two cables :
- high voltage cable and signal cable (Cable1),
- signal cable has on Main unit side 25 pins SUB-D connector.
LASER HEAD sub-units are :
- TRIGGER,
- SHUTTER,
- ENERGYMETER,
- AIMING BEAM,
- SLIT / INTERLOCK,
- ENERGY DISPLAY (Option).
1-3-2-1 TRIGGER
The flash lamp of the laser head is power supplied via this trigger
board which is controlled by the CPU board.
1-3-2-2 SHUTTER
Purpose of a safety Shutter is to block the Laser pulse when it is not
wanted. Shutter is controlled by the CPU board via the Interface board.
There are two position detections : - when the shutter is closed,
- when the shutter is opened.
1-3-2-3 ENERGYMETER
ENERGY METER is measuring the energy of each laser pulse.
The calibration is done at two power levels : - 3mJ with P1.
- 10mJ with P2.
1-3-2-4 AIMING BEAM
Power is provided by a 1mW laser diode with the wavelenght of 637nm.
The intensity of a light is set by the knurled potentiometer on the right
side of the laser head.
1-3-2-5 SLIT / INTERLOCK
The slit lamp generator position is detected by a magnetic sensor just
below.
1-3-2-6 ENERGY DISPLAY
The option Energy display takes place between the oculars and the slit
lamp.
