Faults that are diagnosed by the GSC+ are shown to service personnel in the display area of the GSC+. The GSC+ uses the following information to tell service personnel about a fault: dedicated following shutdown indicators (1), fault shutdown indicator (3),, fault alarm indicator (4), "DIAG" indicator (8), upper display (5) and lower display (6). Perform the following procedure in order to identify the fault that is detected by the GSC+.
Note: The "DIAG" indicator (8) functions when diagnostic information is available from the GSC+.
- Make a note of the indicators that are functioning on the left side of the "GSC+".
- View the fault code on the upper display (5). If the fault alarm indicator (4) is FLASHING and no fault code is present on the upper display (5), press the alarm codes key in order to view the fault code.
- Note the condition of the "DIAG" indicator (8). The "DIAG" indicator will flash CONTINUOUSLY or the "DIAG" indicator will NOT flash.
- Locate the fault indicator that is functioning on Table 1.
- Go to the second column in Table 1. Find the fault code that is presently shown on the upper display (5) .
- Go to the third column in Table 1 which describes the status of "DIAG" indicator (8) .
- Read the last two columns in Table 1 in order to find the type of fault and corresponding topic within this module.
