10.6.3. I
2
C BUS
Operation of the I
2
C bus can be verified by observing the behavior of D1 on the relay PCA & D2 on the Valve
Driver PCA . Assuming that the DC power supplies are operating properly, the I
2
C bus is operating properly if: D1
on the relay PCA and D2 of the Valve Driver PCA are flashing
There is a problem with the I
2
C bus if both D1 on the relay PCA and D2 of the Valve Driver PCA are ON/OFF
constantly.
10.6.4. TOUCH-SCREEN INTERFACE
Verify the functioning of the touch screen by observing the display when pressing a
touch-screen control button. Assuming that there are no wiring problems and that the DC
power supplies are operating properly, but pressing a control button on the touch screen
does not change the display, any of the following may be the problem:
The touch-screen controller may be malfunctioning.
The internal USB bus may be malfunctioning.
You can verify this failure by logging on to the instrument using APICOM or a terminal
program. If the analyzer responds to remote commands and the display changes
accordingly, the touch-screen interface may be faulty.
10.6.5. LCD DISPLAY MODULE
Verify the functioning of the front panel display by observing it when power is applied to
the instrument. Assuming that there are no wiring problems and that the DC power
supplies are operating properly, the display screen should light and show the splash
screen and other indications of its state as the CPU goes through its initialization process.
