Configure for Intended Use

As described in "General Information", the engine in this
unit runs at low speed when the LED lights are operating
and no loads are connected to the 120 or 240V
convenience outlets. The engine runs at high speed
when the LED lights are turned off. Therefore, before
starting, determine if auxiliary equipment will be
connected to the convenience outlets. Then set up the
unit based on the intended use:
LED Lights Only
Turn the 240V outlet breaker OFF. The engine will run at
low speed while operating, greatly reducing sound
emissions and fuel consumption.
LED Lights and Export Power
Turn the 240V outlet breaker ON and Load Sense OFF.
The engine will run at high speed for powering high
amperage equipment.
LED Lights and Export Power with Load Sense
Turn the 240V outlet breaker ON and Load Sense ON.
The engine will run at high speed when detecting applied
load(s) such as hand tools and low amperage equipment.
Table 3-1 illustrates the four possible combinations of
240V outlet breaker and Load Sense switch positions.
