INITIAL ERROR MESSAGES
As soon as the UPS is first turned on, it performs a series of self tests. If the self tests fail then the UPS will report the failure and display the fault. If the self test passes, but the UPS was shut down previously due to a fault, the previous fault code or message will be displayed. This feature allows you to determine why the UPS shut down. The LCD screen will display the words “Error Detected” on the top line of the screen, and one of the messages in the Error Code list is shown on the second line.
