Low Fuel (Level/Pressure) Switch

Some gas-fueled models offer a low fuel pressure
switch. The low fuel pressure switch connects to the
same controller terminal as the low fuel level switch on
diesel-fueled models. See Figure 6-9, Figure 6-10, and
Figure 6-11.
Note: The main tank or the transfer/day tank includes
the low fuel level switch. The fuel tank supplier
typically provides the low fuel level switch.

Prime Power Switch Kit

The prime power switch kit prevents battery drain during
generator set non--operation periods and when the
generator set battery cannot be maintained by an AC
battery charger. See Figure 6-12 for an illustration of the
kit and Figure 6-13 for the electrical connections.
Stop the generator set using the stopping procedures in
Section 2.3.2, Stopping, before placing the generator
set in the prime power mode. Move the prime power
switch located on the junction box to the DOWN
position. The controller including the digital display,
LEDs, and alarm horn does not function when the
generator set is in the prime power mode.
Move the prime power switch located on the junction box
to the UP position. The generator set is now ready for
starting.
