A Power Array self test measures system performance by se-
quentially placing each power module on battery and then
briefly placing all of the power modules on battery.
1. The following sequence will initiate a Power Array self
test:
Fig 7-13 Initiate a Self Test Sequence
2. The PowerView displays the message Self Test In Progress
while the system performs the test.
Note: A series of clicking sounds can be heard during a self test.
3. The PowerView will either report that the self test was
completed with no errors or will report any failures detected.
4. Press the Escape key and return to the startup screen.
Note: If a power module is diagnosed as bad, see Chapter 8.
Alarm Threshold Status Screen
Fig 7-11 Sample Alarm Threshold Status Screen
Alarm Thresholds - The alarm threshold status screen dis-
plays the user-defined fault tolerance threshold, the maxi-
mum load threshold, and the minimum runtime threshold.
Fault Tolerance: An audible alarm will sound if the level of
redundancy drops below the displayed level.
Load Threshold: An audible alarm will sound if the attached
load exceeds the displayed load threshold.
Runtime: An audible alarm will sound if the predicted run
time becomes less than the displayed minimum runtime
threshold (either because of loss of battery capacity or in-
creased load).
After the alarm threshold status screen has been reviewed,
press the Enter key. The miscellaneous status screen appears.
Note: These alarm thresholds will be configured for your spe-
cific power requirements in step 4.
Miscellaneous Status Screen
Fig 7-12 Sample Miscellaneous Status Screen
The Miscellaneous Status Screen - displays the following in-
formation:
Self Test: Displays the results of the last self test that was
perfomed by the Power Array.
Last transfer (Lst Xfr): Displays the reason for the last trans-
fer to battery.
Status: Displays the current mode of operation.
Note: See the Introduction Chapter for details about operating
modes.
IM: Displays the status of the main intelligence module.
RIM: Displays status of the redundant intelligence module.
The miscellaneous status screen is the final status screen. Press
the Escape key to return to the startup screen.
