ADJ 1
Adjusting high voltage values
NOTE: Adjusting the output voltage requires the ability to measure
internal impedance of 1000
:
. In addition, use high voltage
probe together. (FLUKE87FLUKE80K-40 is recom-
mended.)
1-A
Adjust the main charger grid voltage
This adjustment is needed in the following situations:
* The high voltage power PWB (MC/DV/TC) has been replaced.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.
(Main charger grid voltage adjustment)
1)
Remove the rear cover of the machine.
2)
Apply a digital multi-meter to the connector CN2 pin (3) of the
high voltage PWB and the chassis GND.
3)
Go through the modes specified in Simulation 8-2.
4)
Select the number that corresponds to the adjustment item
using the numeric keypad.
5)
Press the Start key.
6)
Press the start key to have the voltage output for 30 seconds.
The operation can be stopped with the SYSTEM SETTINGS
key.
If the output voltage is not within the requirement, do the fol-
lowing steps.
7)
Enter the adjustment value using the numeric keypad.
8)
Press the Start key.
(The adjustment value is put into memory, and the correspond-
ing voltage is output for 30 seconds.)
Repeat steps 7 to 8 until the output requirement is satisfied.
