The Battery Open Test feature will detect if the connection between the battery and ATevo has been lost, or if there is a weak or faulty battery. The test lowers the charger voltage and verifies whether the battery can assume the present dc load. This test can be run manually or according to a set schedule.

The Battery Open Test will fail if the dc bus drops below a configurable voltage set point. When such occurs the test aborts immediately and ATevo will raise output voltage back to the present Float or Equalize setting. Test duration is configurable as seen below.

If the test fails, a Battery Open alarm is generated and can only be cleared by the Unlatch Battery Open Alarm control.
