System Testing & Troubleshooting
DIAGNOSTICS Menu
The DIAGNOSTICS menu is used to view diagnostics that
have resulted from system failures within the unit. There are
two lists where diagnostics reside; the Active list, and the
Diagnostic Event Log.
The Active list is used for viewing all active diagnostics and
for clearing manually resetable diagnostics. This list of diag-
nostics are displayed after pressing the DIAGNOSTICS key
if active diagnostics are present.
Active manual diagnostics can be cleared in batch form at
the unit mounted Human Interface. When an Active diag-
nostic is manually or automatically cleared, it is removed
from this buffer. Automatically resetting diagnostics can not
be reset by the Human Interface, because the condition
which caused the diagnostic has to be corrected for the di-
agnostic to clear.
The word “MORE” is displayed on all screens if more than
one diagnostic exists, except for the last diagnostic. Upon
reaching the last diagnostic, the word “MORE” disappears.
Pressing the NEXT key at this point causes the display to
advance to the first diagnostic in the Diagnostic Event Log.
The Diagnostic Event Log screens are displayed after
scrolling through the Active list or after pressing the
DIAGNOSTICS key when no active diagnostics are present.
It’s used to view the past 20 diagnostics. Diagnostics in this
log are stacked in inverse chronological order, with the first
diagnostic screen being the most recently reported diagnos-
tic.
When a new diagnostic is displayed, the words “NOT
VIEWED” are displayed with it. After viewing the last
unviewed diagnostic, the words "NOT VIEWED" change to
"VIEWED" for every diagnostic in the log. The diagnostic
will remain this way as long as it is in the log. This allows
the operator to distinquish between old and new diagnostics
in the Event Log.
Pressing the NEXT key after reaching the last diagnostic in
the Event Log advances the display to the first diagnostic in
the Active list if any exist. If not, the display reverts back to
the first Event Log diagnostic. If the Diagnostic Event Log is
full (20 events), and another diagnostic occurs, the oldest
diagnostic is pushed off the end of the list. If all 20 diagnos-
tics in the list are active when the 21st occurs, then the old-
est Active diagnostic is pushed off the end of the list. When
an Active diagnostic is automatically or manually cleared in
the Active buffer, its status in the Diagnostic Log changes
from Active to History. If the operator does not clear an ac-
tive diagnostic in the Active log, its status will still show as
Active in the Diagnostic Log.
When a diagnostic screen is displayed for more than four
hours without a key being pressed, the screen will return to
the operating status display.
One of the following screens will be the first screen displayed when
the DIAGNOSTIC" key is pressed.
