Issue:
This document explains how to perform a manual self-test on an Easy-UPS.
Product Line:
Easy-UPS Online
Environment:
All models, all serial numbers.
Cause:
The self-test function on the UPS is used to test the battery health and internal subsystems of the UPS .
Resolution:
By default all Easy-UPS products will perform a Self Test when you initially turn the UPS on, and then once every 2 weeks from that point forward. This can be adjusted via PowerChute, or the Network Management Card. The interval will always begin when you last turned the UPS on.
During a self-test the UPS will run on battery for approximately 10 seconds. During this time it will test it's internal subsystems as well as the battery. For a battery test to be valid, it should be charged to 100% before beginning the test. If an issue is encountered the self test will be aborted and the UPS will immediately return on to online operation. If the battery performance indicates a failing battery, the UPS will signal a bad battery via the replace battery LED and/or LCD screen. It will also notify users via PowerChute or a Network Management Card if so equipped.
Self Tests can also be manually initiated at any time via PowerChute, The Network Management Card, or the front panel of the UPS.
To manually start a Self Test from the UPS display:
- Press the Enter button.
- Press the Down button until you get to tSt and press enter.
- The UPS will start a count down from 10 seconds and the on battery icon will flash on the display.
- The UPS will display the result of the self test.
The display will show one of the following as the result of the self-test:
SELFTEST FUNCTION:
A new unit with self-test capability will automatically run a self-test on start-up and then run periodic tests on a set schedule, often every 14 days by default. During the test, the UPS will place the load onto battery power to test the strength of the battery.
