2.3.7— Low Fuel Pressure Warning
•
Some gaseous units are equipped with a low fuel pressure warning switch which will trigger a Warning alarm if
the fuel pressure drops below a minimum setting.
•
Diesel units with fuel tanks are equipped with High and Low fuel level warning alarms, as well as a low fuel level
shutdown alarm.
2.4 — DC Fuses
Located inside the front panel, the fuses protect the control panel wiring and components from damaging overload. For
fuse location and identification, see Figure 3-4.
2.5 — Fuel System
This generator set is equipped with one of the following fuel systems:
•
Diesel fuel system
•
Natural Gas (NG) fuel system
•
LP gas vapor withdrawal fuel system (LPV)
•
LP gas liquid withdrawal fuel system (LPL)
•
Dual fuel system: Natural Gas (primary fuel source), LP gas vapor (secondary fuel source)
•
Dual fuel system: Natural Gas (primary fuel source, LP gas liquid (secondary fuel source)
2.5.1— Diesel Fuel System
The manufacturer recommends the use of No. 2 diesel fuel when temperatures are above freezing, and No. 1 diesel
fuel when temperatures drop below freezing. Diesel fuel must meet the following requirements:
Beginning October 1, 2010, owners and operators that use diesel fuel must use diesel fuel that meets:
•
Sulfur content of 15 parts per million (ppm) maximum.
•
Cetane index or aromatic content as follows: A minimum cetane index of 40, or a maximum aromatic content of
35 volume percent.
2.5.2— Natural Gas Fuel System
Natural gas is supplied by a local utility in its vapor state through in ground piping.
2.5.3— LP Fuel System
