If all circuit boards pass the self test, the coded number
disappears and normal operation can begin. If not, the re-
sulting number on the Main Panel Display remains and
only a continuation of the Resident Test Procedure can
be run.
If an installed optional board contains severe faults, as
determined by the Self Test, it may be shown as not in-
stalled, thereby permitting normal operation to begin. A
board designated as not installed by the Self Test is also
considered absent by the operating program and its asso-
ciated features are disabled.
The Cyclic Self Test is identical to the Self Test Routine
previously described, except that it is continuously re-
peated. Its purpose is to assist in locating intermittent
failures by long term testing of the console functions.
When the test is stopped, all failures occurring during
the running period can be identified by interpreting the
resulting number that appears on the Main Panel Display.
Note:
The Cyclic Self Test is for use by qualified
maintenance personnel. If it is started acciden-
tally (by pressing S1 twice when the Self Test
Routine number is displayed), it can be exited
to resume normal operation, if there are no
failures, by pressing ENTER on the keypad
whenever the Self Test number is again dis-
played.
The Diagnostic Monitor is the main troubleshooting
mode of the Resident Test Program. It provides interac-
tion with console circuits via front panel controls, and al-
