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.

Standby Generator Sets
Engine Protective Devices

OIL PRESSURE SENSING

ENGINE PROTECTIVE DEVICES

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.

An analog Oil Pressure Sender (OPS) is used for
monitoring the engine oil pressure. This sender
allows the control panel to measure and display the
Engine oil pressure.
The OPS is a resistive device, whose resistance
changes based on engine oil pressure. The resistance
of the sender results in a voltage being developed
across the sender. As the oil pressure increases,
the resistance will decrease, causing the voltage to
decrease. This changing voltage is converted to 420mA signal by a signal conditioner module. The
corresponding 4-20mA signal is read by the control
panel and displayed as the oil pressure.

NOTE:
Engine protective switches and sensors are mentioned here for the reader's convenience. Also refer
to the applicable control panel manual for additional automatic engine shutdown information.

The control panel will monitor and display oil pressure anytime the DC input to the control panel is
present.

COOLANT TEMPERATURE SENSING
An analog Water Temperature Sender (WTS) is located in the engine's cooling system. This sender is connected to the panel and allows the panel to monitor
and display the temperature of the coolant system.

Should the oil pressure drop below the 8 psi range,
the engine shutdown is initiated. The unit should not
be restarted until oil is added. Turn the AUTO/OFF/
MANUAL switch to the OFF position, then back to
AUTO to restart.

The WTS is a resistive device whose resistance changes based on coolant temperature. The resistance of
the sender results in a voltage being developed across
the sender. As the Coolant temperature increases,
the resistance will decrease, causing the voltage to
decrease. This changing voltage is converted to 420mA signal by a signal conditioner module. The
corresponding 4-20mA signal is read by the control
panel and displayed as the coolant temperature.

OVERCRANK SHUTDOWN
When the control panel receives a start signal, it initiates the programmed starting sequence. The start
sequence consists of the number of crank attempts,
the length of each crank attempt, and the rest time
between each crank attempt. If the engine has not
started by the end of the final crank attempt, an
Overcrank alarm is generated, the control panel will
sound the alarm and display the message "Failed to
start".

The control panel will monitor and display the coolant temperature anytime the DC input to the control
panel is present.

OVERSPEED SHUTDOWN

If the temperature exceeds approximately 140° C
(284° F), the engine shutdown will be initiated. The
generator will automatically restart and the display
will reset once the temperature has returned to an
operating level.

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 over speed 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
A Low Coolant Level (LCL) sensor is placed in the
generators coolant system. This sensor allows the
panel to detect a Low Coolant Level condition.

RPM SENSOR LOSS SHUTDOWN

The LCL is a resistive device whose resistance changes
rapidly based on the presence or absence of coolant.

If the speed signal to the control panel is lost, engine
shutdown will occur.

The resistance of the LCL results in a voltage being
developed across the LCL. This voltage changes as
the resistance changes. This changing voltage is converted to 4-20mA signal by a signal conditioner module. The corresponding 4-20mA signal is read by the
control panel and displayed as the low coolant level.

DC FUSE
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.)
4-1

EngProt002 Rev. B 10/05

If the level of the engine coolant drops below the level
of the low coolant level sensor, the engine shutdown
will be initiated.

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
• Liquid propane (LP) 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 Btu's per cubic foot for natural gas; or at
least 2,520 Btu's per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 11 inches
to 14 inches water column (0.4 to 0.5 psi); and for
liquid propane, 11 inches to 14 inches of water
column (0.4 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 11 inches
water column for natural gas or 11 inches water
column for liquid propane 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).

5.4L & 6.8L IGNITION DESCRIPTION

NOTE:

This single-fire Ignition is intended to operate with
a 10-cylinder, 6.8L engine and an 8-cylinder, 5.4L
engine.

The ignition cover does not need to be removed to
see the LED.

The 6.8L engine uses a 40-1 crank sensor, a magpickup CAM sensor and individual coil-on-plug coils
for each spark-plug.

IGNITION SHUTDOWN ON LOSS OF CRANK
OR CAM SIGNALS
The ignition will stop firing the coils immediately following the loss of the crank signal. The ignition will
stop firing the coils after approx. 3 seconds following
the loss of the cam signal.

The 5.4L engine uses a 36-1 crank sensor, a magpick-up CAM sensor and individual coil-on-plug coils
for each spark-plug.
With a single-fire ignition, each high-voltage coil output is connected to one spark plug resulting in that
spark plug being fired only during the compression
cycle.

DIAGNOSTIC BLINK PATTERNS (RED LED
LOCATED ON THE IGNITION CONTROL
BOARD)

Engine Timing versus Engine Speed for the 6.8L
engine is:

During normal ignition operation the RED LED
flashes at a 0.5 sec ON and a 0.5 sec OFF rate. This
is considered one (1) blink.

3.0 seconds and then repeats
2. No CAM Signal: LED blinks 3 times, is OFF for
3.0 seconds and then repeats
Only one fault is displayed at a time. If multiple faults
exist then the highest priority fault must be resolved
prior to a lower priority fault being displayed. In the
event that an ignition fault has occurred the ignition
will wait 60 seconds before powering down.

IGNITION POWER-UP INPUT ("56 LINE
INPUT")
When battery voltage is applied to this input the ignition will power-up. For the ignition to power itself
down, battery voltage must be removed from this
input.

NOTE:
The ignition cover does not need to be removed to
see the LED.

IGNITION ENABLE ("14 LINE INPUT")
This input must be connected to the +12V battery for
the ignition to turn-on the coils. If this input is connected to battery ground the ignition will stop firing
the coils and will power down within approximately
2 seconds. In the event that an ignition fault has
occurred, however, the ignition will wait 60 seconds
before powering down. This allows time to view the
diagnostic LED located on the ignition board.

General Information

GENERATOR AC LEAD CONNECTIONS

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
breaker terminal and the neutral point 00 is 120V.

between pulleys, deflects the belt about 3/8- to 5/8inch (10 to 16 mm).

If this generator is used to supply power to any electrical system normally powered by an electric utility,
the National Electrical Code requires that a transfer
switch be installed. The transfer switch prevents electrical backfeed between two different electrical systems. (For additional information, see the applicable
transfer switch manual for this unit.) The transfer
switch, as well as the generator and other standby
components, must be properly located and mounted
in strict compliance with applicable codes, standards
and regulations.

CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible.
Dirt and moisture that accumulates on internal generator windings have an adverse effect on insulation
resistance.
Periodically clean generator exterior surfaces. A soft
brush may be used to loosen caked on dirt. Use a
vacuum system or dry, low pressure air to remove
any accumulations of dirt. The generator is housed
inside an all-weather enclosure, clean the enclosure
with a soft, damp cloth or sponge and water.
Once each year, have the generator cleaned and
inspected by an Authorized Service Dealer. That
dealer will use dry, low pressure air to clean internal
windings. Parts inside the control console should be
cleaned and inspected at this time as well.

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.
