Faults that are detected and diagnosed by the GSC are shown to service personnel in the display area of the GSC. The GSC uses dedicated shutdown indicators (1), fault shutdown indicator (2), fault alarm indicator (3), "DIAG" indicator (5), upper display (4) and lower display (6) to tell service personnel about a fault. Perform the following procedure in order to identify the fault that is detected by the GSC.
Note: "DIAG" indicator (8) functions (either FLASHING or ON CONTINUOUSLY) whenever the diagnostic information is available from the GSC.
- Note the indicators that are functioning on the left side of the GSC.
- View the diagnostic code on upper display (4). If the fault alarm indicator (3) is FLASHING and no diagnostic code is present on upper display (4), press the alarm codes key to view the fault code.
- Note whether or not "DIAG" indicator (5) is FLASHING, ON CONTINUOUSLY, or NOT PRESENT.
- Look at the first column on the table 1 and locate the fault indicator that is functioning.
- Go to the second column in the table 1 and find the fault code that is presently shown on upper display (4).
- Go to the third column in the table 1 which describes the status of "DIAG" indicator (5) .
- Read the last two columns in order to find the type of fault and the corresponding topic.
