SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation
be copied and posted in potential hazard areas. Safety should be stressed to all operators,
potential operators, and service and repair technicians for this equipment.

Standby Generator Sets
Important Safety Instructions

• Generators installed with an automatic transfer
switch will crank and start automatically when
normal (utility) source voltage is removed or is
below an acceptable preset level. To prevent such
automatic start-up and possible injury to personnel, disable the generator’s automatic start circuit
(battery cables, etc.) before working on or around
the unit. Then, place a “Do Not Operate” tag on
the generator control panel and on the transfer
switch.
• In case of accident caused by electric shock, immediately shut down the source of electrical power.
If this is not possible, attempt to free the victim
from the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting implement, such as a dry rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.

• Before performing any maintenance on the generator, disconnect its battery cables to prevent
accidental start-up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.

 ELECTRICAL HAZARDS 

• All generators covered by this manual produce
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch
as well as the standby generator. Avoid contact
with bare wires, terminals, connections, etc., on
the generator as well as the transfer switch, if
applicable. Ensure all appropriate covers, guards
and barriers are in place before operating the generator. If work must be done around an operating
unit, stand on an insulated, dry surface to reduce
shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
• If personnel must stand on metal or concrete while
installing, operating, servicing, adjusting or repairing this equipment, place insulative mats over a
dry wooden platform. Work on the equipment only
while standing on such insulative mats.
• The National Electrical Code (NEC) requires the
frame and external electrically conductive parts
of the generator to be connected to an approved
earth ground. This grounding will help prevent
dangerous electrical shock that might be caused
by a ground fault condition in the generator set or
by static electricity. Never disconnect the ground
wire.
• Wire gauge sizes of electrical wiring, cables and
cord sets must be adequate to handle the maximum electrical current (ampacity) to which they
will be subjected.
• Before installing or servicing this (and related)
equipment, make sure that all power voltage
supplies are positively turned off at their source.
Failure to do so will result in hazardous and possibly fatal electrical shock.
• Connecting this unit to an electrical system normally supplied by an electric utility shall be by
means of a transfer switch so as to isolate the
generator electric system from the electric utility
distribution system when the generator is operating. Failure to isolate the two electric system power
sources from each other by such means will result
in damage to the generator and may also result
in injury or death to utility power workers due to
backfeed of electrical energy.

 FIRE HAZARDS 
• Keep a fire extinguisher near the generator at all
times. Do NOT use any carbon tetra-chloride type
extinguisher. Its fumes are toxic, and the liquid
can deteriorate wiring insulation. Keep the extinguisher properly charged and be familiar with its
use. If there are any questions pertaining to fire
extinguishers, consult the local fire department.

 EXPLOSION HAZARDS 
• Properly ventilate any room or building housing
the generator to prevent build-up of explosive gas.
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.
• These generator sets may operate using one of
several types of fuels. All fuel types are potentially
FLAMMABLE and/or EXPLOSIVE and should be
handled with care. Comply with all laws regulating the storage and handling of fuels. Inspect the
unit’s fuel system frequently and correct any leaks
immediately. Fuel supply lines must be properly installed, purged and leak tested according to
applicable fuel-gas codes before placing this equipment into service.
• Diesel fuels are highly FLAMMABLE. Gaseous
fluids such as natural gas and liquid propane
(LP) gas are extremely EXPLOSIVE. Natural gas
is lighter than air, and LP gas is heavier than air;
install leak detectors accordingly.

Engine Protective Devices

ENGINE PROTECTIVE DEVICES

‹ OVERCRANK SHUTDOWN

The standby generator may be required to operate for
long periods of time without an operator on hand to
monitor such engine conditions as coolant temperature, oil pressure or rpm. For that reason, the engine
has several devices designed to protect it against
potentially damaging conditions by automatically
shutting down the unit when the oil pressure is too
low, the coolant temperature is too high, the coolant
level is too low, or the engine is running too fast.

After a prespecified duration of cranking, this function ends the cranking if the engine has failed to
start. The overcrank LED will turn ON. Turn OFF the
AUTO/OFF/MANUAL switch, then turn switch back to
AUTO to reset the generator control board.
NOTE:
If the fault is not corrected, the overcrank feature
will continue to activate.

NOTE:

‹ HIGH COOLANT TEMPERATURE SWITCH
This switches contacts close if the temperature should
exceed approximately 140° C (284° F), initiating an
engine shutdown. The generator will automatically
restart and the LED will reset once the temperature
has returned to a safe operating level.

15 seconds ON

Repeat for 45 seconds
Approximately 90 seconds total.

‹ OVERSPEED SHUTDOWN
A speed circuit controls engine cranking, start-up,
operation and shutdown. Engine speed signals are
delivered to the circuit board whenever the unit is
running. Should the engine overspeed above a safe,
preset value, the circuit board initiates an automatic
engine shutdown. Contact the nearest Authorized
Dealer if this failure occurs.

‹ LOW COOLANT LEVEL SENSOR
Should the engine coolant level drop below the level
of the high coolant temperature switch, it is possible
for the engine to overheat without automatic shutdown. To prevent such overheating, the engine has a
low coolant level sensor. If the level of engine coolant
drops below the level of the low coolant level sensor,
the engine automatically shuts down.

‹ RPM SENSOR LOSS SHUTDOWN
If the speed signal to the control panel is lost, engine
shutdown will occur.

‹ DC FUSE

‹ LOW OIL PRESSURE SWITCH

This fuse is located inside of the control panel. It
protects the panel wiring and components from
damaging overload. Always remove this fuse before
commencing work on the generator. The unit will
not start or crank if the fuse is blown. Replace the
fuse with one of the same size, type, and rating. (See
the exploded views and parts lists at the end of this
manual for replacement part number.)

EngProt001 Rev. 0 08/05

This switch has normally closed contacts that are
held open by engine oil pressure during cranking and
operating. Should oil pressure drop below the 8 psi
range, switch contacts close, and the engine shuts
down. The unit should not be restarted until oil is
added, and the AUTO/OFF/MANUAL switch must be
turned to OFF and then back to AUTO.

Standby Generator Sets
Fuel Systems

FUEL SYSTEM

‹ PROPANE VAPOR WITHDRAWAL FUEL SYSTEM

‹ FUEL REQUIREMENTS

This type of system utilizes the vapors formed above
the liquid fuel in the supply tank. Approximately 10
to 20 percent of the tank capacity is needed for fuel
expansion from the liquid to the vapor state. The
vapor withdrawal system is generally best suited for
smaller engines that require less fuel. The installer
should be aware of the following:

The standby generator may be equipped with one of
the following fuel systems:
• Natural gas fuel system
• Propane vapor (PV) fuel system
The Manual Drawing Listing that is affixed to the
unit includes the “Identification Code,” which may be
used to identify the type of fuel system installed on
the unit.

• The natural gas and LP gas systems are similar.
However, the natural gas system delivers gas at a
pressure of approximately five inches water column to the carburetor.
• When ambient temperatures are low and engine
fuel consumption is high, the vapor withdrawal
system may not function efficiently.
• Ambient temperatures around the supply tank
must be high enough to sustain adequate vaporization, or the system will not deliver the needed fuel
volume.
• In addition to the cooling effects of ambient air, the
vaporization process itself provides an additional
cooling effect.

Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 5 inches
to 14 inches water column (0.18 to 0.5 psi); and
for liquid propane, 5 inches to 14 inches of water
column (0.18 to 0.5 psi).
NOTE:
Any piping used to connect the generator to the
fuel supply should be of adequate size to ensure
the fuel pressure NEVER drops below five inches
water column for natural gas or 5 inches water
column for propane vapor for all load ranges.

‹ LP FUEL SYSTEM
LP is supplied as a liquid in pressure tanks. It is
usually made up of propane, butane, or a mixture of
the two gases. Propane tends to vaporize readily even
at temperatures as low as -20° F (-29° C). However,
butane reverts to its liquid state when temperatures
drop below 32° F (0° C).

NOTE:
It is the responsibility of the installer to make sure
that only the correct recommended fuel is supplied to the generator fuel system. Thereafter, the
owner/operator must make certain that only the
proper fuel is supplied.

LP in a liquid withdrawal system must be converted
to its gaseous state before it is introduced into the
engine carburetor. A vaporizer-converter is generally
used to accomplish this. In such a converter, heated
engine coolant is ported through the converter to
provide the necessary heat for conversion of the fuel
from a liquid to a gaseous state.

‹ NATURAL GAS FUEL SYSTEM
Natural gas is supplied in its vapor state. In most
cases, the gas distribution company provides piping
from the main gas distribution line to the standby
generator site. The following information applies to
natural gas fuel systems.
• Gas pressure in a building is usually regulated by
national, state and local codes.
• To reduce gas pressure to a safe level before
the gas enters a building, a primary regulator is
needed. The natural gas supplier may or may not
supply such a regulator.
• It is the responsibility of the gas supplier to make
sure sufficient gas pressure is available to operate
the primary regulator.
• Gas pressure at the inlet to the fuel shutoff solenoid should not exceed approximately 14 inches
water column (0.5 psi). Optimum pressure at the
fuel shutoff solenoid is 11 inches water column
(0.4 psi).

ALTERNATOR POWER WINDING
CONNECTIONS

See “Voltage Codes”. This generator may be rated
at any one of three voltages, either single-phase or
three-phase. The electrical wires in the unit’s AC connection (lower) panel should be installed according to
the number of leads and the voltage/phase required
for the application. If there are any questions regarding lead connection, refer to the wiring diagrams at
the back of this manual.

‹ 3-PHASE ALTERNATORS
The generator is designed to supply 3-phase electrical loads. Electric power is produced in the alternator power windings. These windings were connected
at the factory to the main circuit breaker with a “Y”
configuration as shown in Figures 7.2 and 7.3.

Voltage codes apply to the type of stator assembly
installed on a particular generator.

The rated voltage between circuit breaker terminals
E1-E2, E1-E3 and E2-E3 is either 480V or 208V
depending on the model.

‹ FOUR-LEAD, SINGLE-PHASE STATOR

The rated voltage between each circuit breaker terminal and the neutral point 00 is either 277V or 120V
depending on the model.

Four-lead generators (see Figure 7.1) are designed to
supply electrical loads with voltage code “A” (240V,
1-phase, 60 Hz). Electrical power is produced in the
stator power windings. These windings were connected at the factory to the main circuit breaker as
shown in Figure 7.1.

Figure 7.2 — Stator Power Winding
Connections - 3-phase, 277/480V (6 Lead)

The rated voltage between each circuit breaker terminal is 240V. The rated voltage between each circuit

Service Schedule

SERVICE SCHEDULE
30 KW - 150 KW STANDBY GAS ENGINE DRIVEN GENERATOR SETS
The following is a recommended maintenance schedule for standby gas engine driven generator sets from 30kW to
150 kW in size. The established intervals in the schedule are the maximum recommended when the unit is used
in an average service application. They will need to be decreased (performed more frequently) if the unit is used
in a severe application. Use calendar time, from the previous maintenance interval to determine the next required
maintenance interval.

Service Maintenance Interval Information:
The various service maintenance intervals are designated by interval numbers as follows:
1 An early inspection of the generator set to insure it is ready to operate when required and to identify any potential problem areas.
This inspection may be performed by the end user providing the following safety steps are taken to prevent
the engine from starting automatically without warning:
To prevent injury, perform the following steps in the order indicated before starting any maintenance:
• Disable the generator set from starting and/or connecting to the load by setting the control panel Auto/Off/
Manual switch to the “OFF” position.
• Remove the 15 amp control panel fuse.
• Turn off the battery charger.
• Remove the negative battery cable.
The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condition
from burning out sensitive control panel components and circuits.
Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal
operation when required.
2 A wear-in service inspection of the generator set to insure it is ready to operate and carry the load when
required, and to identify any potential problem areas.
Performed ONLY ONCE following the first three months or the first 30 hours of operation after purchase of
the unit.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by an Authorized Service Dealer.
3 An operational inspection of the generator set to insure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed semi-annually or following each 50 hours of operation of the unit.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by an Authorized Service Dealer.
4 A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed annually or following each 100 hours of operation of the unit.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by an Authorized Service Dealer.
5 A comprehensive inspection of the generator set to insure it is properly serviced and ready to operate and carry
the load when required, and to identify any potential problem areas.
Performed annually or following each 250 hours of operation of the unit.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by an Authorized Service Dealer.

RECONFIGURING THE FUEL SYSTEM
Note: All models are configured to run on natural gas from the factory.

To reconfigure the fuel system from NG to LP, follow these steps:
1. Turn the main gas supply off.
2. Remove the carburetor fuel hose from the outlet port of the demand regulator (See Detail “A”).
3. Disconnect the power wires from the fuel solenoid located on top of the regulator assembly.
4. Loosen the spring clamp on the small fuel enrichment line and remove the hose from the hose barb.
5. Remove the black pipe assembly from the outlet port of the demand regulator.
6. Remove the NG fuel jet (loosen counter clockwise) from the outlet port.
7. Remove the LP fuel jet (loosen counter clockwise) from the jet keeper port on the side of the regulator housing.
Install this jet into the outlet port in the regulator casting.
Note: The jet sizes are stamped on the individual jets. The larger jet size is used for running on NG.

8. Install the previously removed NG jet into the jet keeper port on the side of the regulator housing.
9. Install the previously removed black iron pipe onto the outlet port of the demand regulator.
10. Reverse steps 1-4 in this procedure to reactivate the demand regulator.
11. For LP vapor application substitute LPG fuel inlet decal p/n 050280 for NG fuel inlet decal p/n 050279 (Item 17).
12. When switching fuel types, the proper dip switch settings must be made to the control panel. See owners
manual, fuel section, for more details.
