Error Codes
When the Fault LED
The error codes 1, 2, 4, 8, and 16 are represented by the four bar LEDs 25%, 50%, 75%, and 100%,
and the Overload LED
Each LED represents a number as shown in the figure below.
For example, if the 25%, 50%, and 100% bar LEDs are lit, the error code is therefore 8 + 2 + 1 = 11,
or Er11, which indicates that the UPS is over-temperature.
