OPERATION MODES
Different string codes will display on the LCD module depending on the
conditions the UPS detects. Only one normal operating code or fault code will be
displayed at a time. Warnings though, can appear with several warnings
displayed onscreen even if under normal operating modes. And the normal
operating mode string and the warning string will cycle through on screen. Once
one fault has come forth, all previous warnings will not display again.
