When the system is in AUTO and the generator set is not
running, the LED display shows the engine run time
hours. During cranking, the display shows the crank
cycle information.
When the generator is running, the display steps
through the status messages shown in Figure 4-3, as
applicable. The generator set must be connected to a
Model RRT transfer switch for the utility voltage display.
When a fault or warning condition exists, the controller
will show the respective message. The following table
shows the various generator conditions and expected
