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:

. You are starting your system for the first time.

. You have changed the hardware attached to your system.

. 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.
