If the 10 minute power loss holdup timer runs out (OptiView power will be lost due to turning off
UPS Inverter) before the test completes and power is restored the test is considered failed.
UPS Battery Health Test Successful is displayed for 10 seconds when the test passes.
UPS Battery Health Test Failed – Step X (Where X is the step that failed) is displayed
when the test fails. It remains while the Warning – UPS – Battery Test Failed warning is
active. It and the warning will be cleared when a Battery Health Test completes successfully.
For a fail, the following steps may be indicated as the fail point:
Step 2 is when the OptiView is waiting to sense line power removed – typically the user has
taken too long and exceeded 10 minute test time
Step 3 is during the 60 second battery voltage monitoring under Levitation load – typically
would be a bad battery
Step 4 is after completion of the 60 second monitoring and waiting for successful automatic
de-levitation – would indicate some unplanned failure of the control or communication
Step 5 is waiting to sense line power restored – typically the user has taken too long and
exceeded 10 minute test time
