Reading the Eaton 9170+ System Logs
The Eaton 9170+ system makes an entry in its logs each time it sounds
an alarm or runs on battery power. This information can help in
diagnosing power problems. You can display the UPS Inverter and Alarm
logs on the front panel display in menu 2.
Inverter Log
The inverter (Battery mode) log is in menu 2 1. Move through the menu
structure by pressing the Menu button and pressing the
B
button to
move down to menu 2. Press
to move to submenu 1 and press
again to view the most recent entry in the inverter log.
The log stores up to 10 entries, in chronological order. Use the
B
and
Y
buttons to scroll up and down through the log entries. Each entry shows
the date and time the unit switched to battery operation (in 24-hour
format) and the duration of battery operation (in hours and minutes).
