Table 3. Initialization Sequence.
Step Display Description
1 8.8.8.8. Display test. Displayed for 1 second.
2 AFO RAM test. Displayed for 1 second. If this test
fails, the testing stops and the AFO message
remains on.
3 PF PROM test. Displayed briefly. If this test fails,
the testing stops and the PF message remains
on.
4 . . . . . Normal display mode. Decimal points blink to
indicate processor activity.
5 - - . - Decimal point number three should be
illuminated constantly after about 15 seconds.
This indicates the AC power source is stable
and output circuits are being tested.
The diagnostic messages displayed as the module operates are
used together with the module’s active and fault indicators.
A red FAULT indication on the module together with a
diagnostic message can be caused by either a power, wiring, or
load problem or by a module fault or failure.
A red FAULT indication without a diagnostic message display
can indicate either a failed module or a fault that has already
been corrected. If the fault has been corrected, the diagnostic
message display will clear itself; however the module’s FAULT
indicator must be cleared by a voted reset. If the FAULT
indicator does not clear after a voted reset it is because the
module itself has failed and must be replaced.
