explosive. Use extreme care when
handling and storing fuels. Store fuels
inawell-ventilatedareaawayfrom
spark-producing equipment and out of
the reach of children. Never add fuel to
the tank while the engine is running
because spilled fuel may ignite on
contact with hot parts or from sparks.
Do not smoke or permit flames or
sparks to occur near sources of spilled
fuel or fuel vapors. Keep the fuel lines
and connections tight and in good
condition. Do not replace flexible fuel
lines with rigid lines. Use flexible
sections to avoid fuel line breakage
caused by vibration. Do not operate
the generator set in the presence of
fuel leaks, fuel accumulation, or
sparks. Repair fuel systems before
resuming generator set operation.
Explosive fuel vapors can cause
severe injury or death. Ta k e
additional precautions when using the
following fuels:
Gasoline—Store gasoline only in
approved red containers clearly
marked GASOLINE.
Propane (LP)—Adequate ventilation
is mandatory. Because propane is
heavier than air, install propane gas
detectors low in a room. Inspect the
detectors per the manufacturer’s
instructions.
Natural Gas—Adequate ventilation is
mandatory. Because natural gas rises,
install natural gas detectors high in a
room. Inspect the detectors per the
manufacturer’s instructions.
Fuel tanks. Explosive fuel vapors
can cause severe injury or death.
Gasoline and other volatile fuels stored
in day tanks or subbase fuel tanks can
cause an explosion. Store only diesel
fuel in tanks.
Draining the fuel system. Explosive
fuel vapors can cause severe injury
or death. Spilled fuel can cause an
explosion. Use a container to catch
fuel when draining the fuel system.
Wipe up spilled fuel after draining the

Gas fuel leaks. Explosive fuel
vapors can cause severe injury or
death. Fuel leakage can cause an
explosion. Check the LP vapor gas or
natural gas fuel system for leakage by
using a soap and water solution with
the fuel system test pressurized to
6--8 ounces per square inch
(10--14 inches water column). Do not
use a soap solution containing either
ammonia or chlorine because both
prevent bubble formation. A
successful test depends on the ability
of the solution to bubble.
LP liquid withdrawal fuel leaks.
Explosive fuel vapors can cause
severe injury or death. Fuel leakage
can cause an explosion. Check the LP
liquid withdrawal gas fuel system for
leakage by using a soap and water
solution with the fuel system test
pressurized to at least 90 psi
(621 kPa). Do not use a soap solution

This regulated level setting is the average of the three
The 550 controller has a voltage regulation function that

the controller uses root mean square (rms) sensing for
fast response to changes in indicated and regulated
voltages resulting in excellent regulation accuracy.
Submenus display the individual line-to-line voltages.
These voltages are for reference only and are relevant in
unbalanced load conditions. The voltage adjust setpoint

and utility application to control changes in the reactive
loads due to load changes, prime mover speed
variation, thermal drift, and other variations. See
Figure 1-13 for data on the 550 controller voltage
regulation. Refer to Appendix C to customize
adjustments for specific applications.
Underfrequency Unload Frequency Setpoint. This
adjustment affects the voltage droop (volts per Hz) when
load is applied and underfrequency occurs. The
underfrequency unload setting defines the setpoint
where underfrequency starts. Any frequency below the
setpoint causes the voltage to drop thus reducing the
load allowing the engine speed to recover according to
1.3.3 Voltage Regulator Adjustments
the underfrequency unload slope setting.
The descriptions of the voltage regulator adjustments
and features follow. See Appendix C, Voltage Regulator
Definitions and Adjustments, for additional information.
