  1. 1

    Clear the fault and attempt restart.

  2. 2

    Ensure battery voltage is below HBCO at XW Pro terminals.

  3. 3

    Check all other charging source outputs and battery cables.

  4. 4

    Ensure that batteries are connected, or that your DC source is regulated below your high battery cut out.

  5. 5

    Increase your Hi Batt Cut Out setting.
