DIAGNOSTIC TEST PROGRAM (BUILT-IN TEST)

Diagnostic Tests for the U-COFT are automated, built-in tests to troubleshoot and isolate faults occurring in the SPC

system. Diagnostic Test routines are stored in the GPC Disk Drive. The routines may be called up on the IOS Display

Terminal when a problem with the system sight scenes occurs. There are five different levels of diagnostic test routines

for the U-COFT (1). The only routine to be used for Instructor/Operator troubleshooting is the Image Generator Fault

Isolation routine. If Fault Isolation does not detect the problem, Organizational Maintenance must be notified.

Diagnostic Tests are called up from the Mode Selection display page presented on the Display Terminal (see 2-40).

When the COFT VISUAL SYSTEM DIAGNOSTICS MENU is displayed and number 1 = Image Generator (SPC) Fault

Isolation (2) is selected, the GPC will automatically run the test. As each test function is performed, the test description

(3) is displayed on the Display Terminal.
