8. Troubleshooting

The Eaton 9130 is designed for durable, automatic operation and also alerts you whenever potential
operating problems may occur. Usually the alarms shown by the control panel do not mean that the
output power is affected. Instead, they are preventive alarms intended to alert the user.
In general:
Events are silent conditions that are recorded in the Event Log as status information, such as
"Clock Set Done".
Notices are announced by a beep every 5 seconds, recorded in the Event Log, and displayed on
the LCD. Examples are "UPS on Battery" and "UPS on Bypass".
Alarms are announced by a beep every second, recorded in the Event Log, displayed on the
LCD, and the Alarm indicator illuminates. Examples are "Output Overload" and "Heatsink
Overtemperature".
Use the following troubleshooting chart to determine the UPS alarm condition.
