Battery failure troubleshooting guide

•
when the ADU gives intermittent 'Battery failure' message on the main screen the most likely
cause is not an actual malfunction in the batteries or on the battery charger board. This
document will describe how you can test and determine the root cause of battery problems,
with the help of service menus.
•
Enter the Diagnostics/ Central Electronics/ Battery menu (see figure next page)
•
Try to repeat the problem by:

Write down the data values while performing troubleshooting
•
Check error conditions from Error History and compare the HW
errors to Typical Error Messages
•
Verify/compare the results to Typical Diagnostics Values to determine if the cause is due to
intermittent battery failures
