1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 NOTES ON REPLACING
1.3 SERVICE NOTICE
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.

gCaution of the removal of the Control panel Section
The two FFCs that connect between the Control panel section and the Chassis section are short in length.
Therefore, they cannot be opened 180 degrees with the FFCs still connected.
Be careful not to damage the FFC or the connector when removing the Control panel section or diagnosing it.

gAbout the replacement of the jog LCD
As shown in the figure below, the cover and the jog LCD are fixed with double-sided tape.
Surface side Back side
If you remove the parts from the double-sided tape, the parts will be deformed.
So when replacing the parts, do not reuse them.
Replace the parts at the Assy unit of the service.
g
About the Flash (IC2802) and USB-LAN Conversion IC (IC3802) in the MAIN Assy
Replacement of the Flash (IC2802) and USB-LAN Conversion IC (IC3802) in the MAIN Assy is not possible during service,
because writing of the MAC address on the production line is required and USB-LAN Conversion IC (IC3802) has unique ID.
Therefore, the Flash (IC2802) and USB-LAN Conversion IC (IC3802) are not supplied as a service part.
If the Flash (IC2802) and USB-LAN Conversion IC (IC3802) are defective, replace the whole MAIN Assy.
After replacing the the MAIN Assy, writing of the serial number of the unit is required.
For details on how to write the serial number, see "8.3 WRITING THE SERIAL NUMBER OF THE UNIT."
gAbout the Fan motor
This product has Fan motor.
This fan is controlled with the three thermometers in MAIN CPU (IC1801), which automatically switch the rotation speed
(Off/Low/High).
If the thermometer doesn't detect a very high temperature, Fan doesn't start to rotate.
Fan's rotating status can be checked in Service mode.
Use the above information in addition to "THERMOMETER CHECK PAGE" information of Service mode when replacing Fan
or making a diagnosis.
When repairing the product, always remove Cover of the bottom to check and clean with air blow, etc. the vents for dust.
If it is heavily dusty, remove Fan motor and Stay, and clean it.
gAbout Jog dial rotation load adjustment
When performing the Jog dial rotation load adjustment, you must remove Jog dial section from Control panel section to
operate Adjust plate.
After removing it, connect PNLB Assy and JOGB Assy with 4P extension cable before performing the adjustment.
Remove JOGB Assy from Jog dial section and replace it with 4P extension cable and reinstall it.
After the adjustment is complete, remove JOGB Assy and reinstall it using the cables that were used before disassembly.
After Jog dial section is installed and the product is reassembled, the Jog dial rotation load measurement is performed again
to confirm that there are no problems.

When discharging the above point, use the following discharge jig as needed.
While the charging voltage is left of both C4 and C5, either of checking LEDs turns on.
And if both of LED turns off, we can avoid receiving the electrical shock!!
When there is no above type LED, take measures the following method.
Step 1: After the power is turned off, wait 2 minutes.
Step 2: Connect the Register Jig and leave the unit as it is, for 10 seconds.
!Resister is all 10 kΩ(3W)
!Both of LED is LTL17KRH5D

The circuit of "discharge JIG" is shown below.
gSW POWER SUPPLY Primary side electrical shock
The primary side of SW POWER SUPPLY remains voltage long time, and the primary solder side can be seen.
So if you touch the primary solder side, it is possible to receive an electrical shock.
There is the red area below where we tend to receive an electrical shock.
Be sure to discharge the voltage of primary side to avoid receiving the electrical shock.
Electrical shock area of A-side.

- If it is out of specification, refer to "8.4 JOG
DIAL ROTATION LOAD ADJUSTMENT" for
calibration. Wipe and reassemble Jog dial
(DNK6777) as necessary.
- Apply grease to the shaft if it is low in grease.

JOG section
—2 JOGT circuit
have defect
If confirmed, confirm that the signal reaches the
panel microcomputer. If not confirmed, confirm
the signal circuit. If the signal is reaching the pins
of PANEL CPU but the touch operation cannot be
detected, replace PANEL CPU.
If not confirmed, disassemble Jog Assy and move
on to the internal checking.
Confirm that the signal is input to pin 2
(JOGT) of CN7206 when the jog is touched.
PNLB Assy
—3 The sensor has
defect
Install Sensor correctly. Replace Sensor if it has
dirt, damage, or moisture in it.
Confirm that Sensor is properly installed
and that Sensor is not dirty, damaged or
contaminated with water.
Sensor (Sheet switch)
—4 COIL2 has defect Repair defective solder and defective connections
if found.
Confirm the circuit from Sensor to COIL2
Assy, and confirm that there is no defective
soldering on the parts of COIL2 Assy.
COIL2 Assy
—6 JLCD has defect If not confirmed, replace the parts in the order of
JLCD Assy, COIL2 Assy and COIL1 Assy.
Confirm that the voltage of pin 2 (JOG_SW) of
CN7002 change the following state.
1. It changes to about 0.5 V when you stop
touching Jog
2. It changes to about 1.5 V when you touch Jog
JLCD Assy
5 COIL drive circuit
have defect
- Repair the connection between COIL1 Assy and
JLCD Assy if there are connection defects.
- Repair the defective soldering on JLCD Assy, if found.
- If pin 5 of IC7002 (LDO) is not 3.3 V, replace IC7002.
- If pin 4 of IC7003 (LOGIC) is not 8 MHz, replace
X7001 (Resonator) or IC7003.
- If pin 8 of IC7004 (LOGIC) is not 2 MHz, replace
IC7004.
- If the gate of Q7003 (FET) is not 2 MHz, replace
IC7006 (LOGIC).
- If pin 2 of CN7003 is not Half-wave waveform of
2 MHz, replace Q7003 (FET).
Confirm the peripheral circuits of COIL1 Assy
and JLCD Assy.
