Diagnostics and Troubleshooting
This chapter consists of “Self-Test Diagnostics,” “Troubleshooting,” and “Corrective
Actions.” “Self-Test Diagnostics,” describes how to respond to errors that could be
detected by the automatic self test that is performed each time the Panel C industrial
computer powers up. “Troubleshooting” contains tables of symptoms, their possible
causes, and recommended corrective actions. “Corrective Actions” contains detailed
procedures that are too lengthy to include in the Troubleshooting tables.
Self-Test Diagnostics
The computer automatically performs self-test diagnostics each time it is powered up. The
self-test consists of a series of checks that verify correct performance of the computer
hardware. When the self-test is being performed, you will see the message XXXX KB OK
displayed on the screen, where XXXX is a number that increases until it matches the
amount of usable memory.
System Test and Initialization
These routines test and initialize board hardware. If the routines encounter an error during
the tests, you will see an error message on the screen. There are two kinds of errors: fatal
and non-fatal. If a non-fatal error occurs, the system can usually continue the boot up
sequence. Non-fatal error messages usually appear on the screen with the following
instruction:
press <F1> to RESUME
Write down the message and press the F1 key to continue the bootup sequence.
System Configuration Verification
These routines check the current system configuration against the values stored in the
CMOS memory. If they don’t match, the program will generate an error message. To
correct this condition, you will need to run the BIOS setup program and correct the
configuration information in memory.
There are three situations in which you might need to change the CMOS settings:
1
. You are starting your system for the first time.
2
. You have changed the hardware attached to your system.
3
. The CMOS memory had lost power and the configuration information has been
erased. If this has happened, call GE Fanuc’s Support Hotline at 1-800-800-433-2682.
