The second line shows the engine generator state, and whether the engine is OK or in a
fault condition (FLT). This submenu also gives individual generator output as “kW Gen” on
the third line. Note that in High Efficiency Mode, engine generator power that is greater
than what is required to support the load output will be export to the Grid LCM and/or
supplied to the DC bus.
The engine state messages are abbreviations of the actual engine states, as summarized
