6.5 Process Board (H700)
When Process Board (H700) is replaced, the following preparation and adjustments are necessary.
Note: Elapsed time data such as the lamp using time is managed between Process Board (H700) and SBC (F700).
Thus the adjustment of Process Board must be performed with the original SBC Board.
6.5.1 Pump air flow data backup
Because the pump air flow data has been stored in Process Board (H700), the data must be transferred
from the old board to the new one. The data can be read with the following procedures.
Note: If the backup fails, the pump air flow adjustment is necessary after replacing Process Board (H700).
<Procedures>
1) Read the pump air flow data on “Pump Level Adjustment” dialog box with the procedures 2) - 9) of
“6.2.2 Pump air flow adjustment”.
2) Replace the old Process Board (H700) with the new one.
6.5.2 VGA output adjustment
<Equipment>
1) Extension card (ST-5031)
2) Oscilloscope (100MHz)
3) VGA monitor with VGA cable
<Procedures>
Note: Test pins and trimmers are indicated in Photo-15.
1) Connect the extension card (ST-5031) in order to access
the test pins and trimmers on Process board (H700). Be
sure to connect back the VGA inner cable (B522) to CN4
on Process board (H700).
Caution: Pay attention to the connection between the extension
card and Mother Board (E700), the extension card and
Process Board (H700).
2) Connect a VGA monitor to the DVI port of the EPK-i.
Note: 1)VGA monitor is necessary to be connected for the VGA
port termination.
2)“VGA” must be selected for DVI Output in System
Category of Setup menu of the EPK-i. Also select “VGA”
for the signal input of the VGA monitor.
3) Turn ON the EPK-i.
4) Confirm if the VGA monitor shows a plain screen (white).
Note: Process board provided as a spare part usually shows a plain screen. But if it shows a normal screen (Dark
gray screen with the characters), you need to load the jig file (PC provides “33UH071-J1.rbf”). For the way
to load it, please follow the procedures 6.5.3 File update and select file “33UH071-J1.rbf” at procedure 8).
5) Set the oscilloscope as follows:
Ch1: TP74 200mV/div DC 4.00µs/div GND: TP43
Trigger: Ch1 Edge Band limit: 20MHz
6) Adjust RT1 so that the signal attains 700mV+0mV/-20mV (Refer to Fig-3).
7) Check if the signal from TP75 is the same as 700mV+0mV/-20mV (Refer to Fig-3).
8) Check if the signal from TP76 is the same as 700mV+0mV/-20mV (Refer to Fig-3).
