Alarm Threshold Status Screen
Fig 7-11 Sample Alarm Threshold Status Screen
Alarm Thresholds - The alarm threshold status screen dis- plays the
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.

Step 4: Perform a Self Test
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
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.
