View and Reset Alarms
All drive faults and warnings are logged to their respective queues. Collectively
the faults and warnings are referred to as "Alarms". When a new alarm occurs, the
F6 key on any screen will begin to flash in reverse video. Pressing the [F6] key on
any screen will bring you to the screen as shown in
Figure 145 - Alarm Summary Screen
The screen shows the current status of the drive, as well as the last active Fault
that tripped the drive and any pending warning. (The screen only shows a fault
and/or warning if the drive is still in the fault and/or warning state. This is
independent of the content of the queues.) Note: Terminal FRN > 4.005.
To aid in troubleshooting, a time and date stamp is also provided, indicating the
last time the drive was started and stopped for any reason.
To acknowledge the alarm(s), press the [F6] key. This will cause the F6 key to
cease flashing and return to normal video. (If a new alarm were to occur, the F6
key would again flash in reverse video).
To reset the drive, press the [F7] key. This operation will reset any latched faults in
the drive. This has no action upon either the Fault or Warning queues. If some faults
still exist, they will return as new faults.
Faults and Warnings are stored into separate queues. Both work similar, thus only
the fault queue will be discussed. To access the fault queue, press the [F9] softkey from
the ALARM SUMMARY screen.
A screen typical of
will be shown. The screen shows all faults in
chronological order as they have occurred. A timestamp gives the date and time
that the fault occurred. The most recent fault occurs at the top of the list. Use the
[F8] and [F9] keys to shift to other pages if required. Entries are not removed
from the queue until the queue is cleared with the [F7] key. If the queue becomes
full, the oldest entries are discarded to make room for newer faults.
