7 Troubleshooting
The Eaton 5E is designed for reliable, autonomous operation while providing you with notifications and alerts whenever a
potential operational or performance issue occurs.
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.
Events are silent status information that are recorded into the Event log. Example = "AC freq in range".
Alarms are recorded into the Event log and displayed on the LCD status screen with the logo blinking. Some alarms
may be announced by a beep every 3 seconds. Example = "Battery low".
Faults are announced by a continuous beep and red LED, recorded into the Fault log and displayed on the LCD with a
specific message box. Example = Out. short circuit.
