§1 INTRODUCTION

1 - 1

• This service manual is for the OPHTHALMIC YAG LASER SYSTEM YC-1800.

• Be sure to use this manual after understanding the operator’s manual for the OPHTHALMICYAG LASER SYSTEM YC-1800 thoroughly.

• Refer to the OPHTHALMIC YAG LASER SYSTEM YC-1800 Operator’s Manual and PartsList.

• Specifications are subject to change without notice for improvement. Refer to the TechnicalBulletin for important changes.

• In case the system can not be repaired according to the procedures described in this manual,please tell us the serial number of the system and details of the symptom or symptoms.

§2 CAUTIONS

2 - 1

2.1 General

• Servicing should be performed by NIDEK service persons or other qualified personnel.

• Perform all servicing according to the procedures described in this manual. Failure to do somay cause unexpected accident or malfunction.

• Be sure to turn the power off during servicing unless there is an instruction to turn it on.

2.2 During Service

• Take countermeasures against static electricity before the service.

• If malfunction occurs, check the symptom and turn the power off.

• Do not lose or drop removed parts inside the YC-1800.Prepare a case beforehand to store loose parts.

• Take care not to bump the YC-1800.

• Use suitable tools to screw or unscrew the screws.

• Apply a threadlocking adhesive to the screws which have been loosened and tightened again.

• If the YC-1800 produces smoke or strange odors, immediately turn off the system and disconnectthe electrical plug from the outlet.Usage of the system under such abnormal conditions may cause fire or electric shock.

• Do not perform servicing with wet hands.Doing so could cause electric shock or malfunction.

• In §3 TROUBLESHOOTING, when checking a break in a cable, also check the followingaccording to the wiring diagram and connector cable.1. Proper connections and crimping2. Proper contact by connecting and disconnecting connectors3. Proper soldering* Do not yank the cables with excessive force. Doing so could cause breakage.

2.3 During Laser Emission

• Never emit the laser beam directly on personnel or things.

XYC16*RDA001A/E

2 - 2

2.4 Handling the Laser Head

• Never disassemble or repair the laser head.Return the laser head to NIDEK if the repair is necessary. NIDEK will not be responsible foraccidents or malfunction cause by the YC-1800 repaired by other than NIDEK.

2.5 Adjustment

• Adjust the YC-1800 on a vibration free, level, and stable surface.Failure to do so could prevent adjustment from being performed correctly.

• Do not use adjustment jigs for other than the intended purpose.

• Since the Nd:YAG laser used in the YC-1800 is an invisible infrared ray, improper operationmay cause the hazardous exposure to radiation.

• Never face to the laser beam aperture in the laser beam path.

• Wear the safety goggles specified for the Nd:YAG laser.

• Never gaze directly the Nd:YAG laser beam even when wearing the safety goggles.

• Do not touch optical parts such as mirror or lens with bare hands.

• Never expose the laser beam to your skin.

• Take care not to receive electric shock when opening the cover to check or repair the electricalsystem.

• The YAG laser uses the high voltage.

2.6 Using the Energy Meter for the YAG laser

• Depending on the energy meter to be used, the necessity of the dispersion lens, which is attachedto the objective lens at the time of energy measurement, is varied.Refer to the table below when measuring the energy.

• The detector of the energy meter may be damaged if the excessive energy density is applied tothe photoreceptor of the detector.Maximize the spot size of the aiming beam on the photoreceptor as possible so that the YAGlaser beam never come into focus on the photoreceptor.

Check that the actual energy output when the displayed one is 0.5 mJ satisfies the followingstandard.1) Set the YAG laser energy output to 0.5 mJ.2) Press the burst switch to set the pulse number to 1.3) Emit five shots of the YAG laser beam and check that the fifth actual energy output is within

the following standard.[Standard]Actual energy output of 0.5 mJ: Displayed energy output ±15% ±0.1 mJ

7.7 Energy Output Check

1. Press the burst switch to set the pulse number to 1.2. Measure the maximum and minimum energy outputs of the YAG laser beam. Check that

they are within the following standard.3. Perform the same as Step 2 each time the

pulse number is set to 2 and 3.

7.8 Air Plasma Check

Set the energy to 4 mJ and emit the YAG laser beam. Check that the air plasma occurs.

7.9 Parameter Setting

1. Set DIP SW1-6 on the master board to the OFF position.The following displays show the data.1) Address: COUNTER display2) Displayed characters: YAG FOCUS SHIFT display3) Parameter (initial) value: ENERGY display

2. Display Address to be changed with the aiming switches.3. Press the STATUS switch.4. Change the parameter value with the aiming switches.5. Press the reset switch until two short beeps are audible.

The change is completed.6. Set DIP SW1-6 on the master board to the ON position.

7.10 Service Mode Indication

1. Start the YC-1800 while pressing the STATUS (READY mode) and burst switches.2. Press the + aiming switch to change the following.

1) Total shot number (displayed number × 1000 shots)2) Historical error number3) Program version number

7.11 Output Adjustment Mode

Start the YC-1800 while pressing the STATUS (READY mode) and two aiming switchessimultaneously. So, the energy display setting and aiming beam output adjustment are possiblewith the control panel.

7.12 Vertical Movement Base

1. Remove the vertical movement cover.(Refer to 5.4.)

2. Loosen SB3 × 102.3. Adjust the vertical movement nut (34500-

M234) so that the base moves vertically andsmoothly when the joystick is rotated.

4. Tighten SB3 × 102 to fix the nut.5. Reassemble the vertical movement cover.

(Refer to 5.4.)

7.13 Smart Switch Adjustment

1. Adjust parameter for Address 109 so that the energy control is rotated and the value onthe ENERGY display is changed slightly when the smart switch is moved to the right andleft.

2. Move the smart switch to either of the right and left and immediately move it to anotherside. At that time, adjust parameter for Address 108 so that the energy control is rotatedand the value on the ENERGY display is changed slightly.

3. Perform Step 1 again.
