5.2.7 UPS Tests
The UPS Tests menu allows the user to access sub-menus that show operation confirmation functions.
This screen shows the audible alarm test sub-menu. When the Do key is
pressed, the UPS will briefly sound the audible alarm.
This screen shows the battery test sub-menu. When the Do key is pressed,
the UPS will perform a self test to determine the readiness of the UPS and
the batteries to operate the load while on-battery. When conducting this test,
the UPS operates on-battery. The UPS does not signal the on-battery condition
at the computer interface port during this test. The display will report PASS
or FAIL at the end of the test.
This screen shows the battery run time calibration test sub-menu.
To calibrate the UPS’s run time display following installation, press
the Do key. If the calibration test is not conducted, the UPS provides
only a rough estimate of run time until actual battery statistics can be
acquired during an extended utility failure.
When the Do key is pressed, the UPS will perform the test only if battery
capacity is at 100%. The test is completed and the UPS returns to normal
on-line operation when the batteries are discharged to approximately
25% of their full capacity. The calibration test can be aborted at any
time during the test.
5.2.8 Password protection
All functions accessed by the UPS Control, UPS Setup and UPS Tests menus may be password protected to prevent
operation of the unit in a fashion not intended by the UPS manager. The password settings are accessed by optional UPS
monitoring application software.
