LED Indicators

LEDs above the RUN, OFF, and AUTO buttons indicate
the mode of operation as shown in Figure 3-4.
Power System LEDs indicate the status of the utility
power and the generator set, and indicate which source
is supplying power to the building (based on the position
of the RXT transfer switch). See Figure 3-2 and
Figure 3-4.
Note: The power system LEDs operate only if a Model
RXT transfer switch is connected. They will not
operate if a different transfer switch is used.
