equipment.

SAFETY RULES
Study these SAFETY RULES carefully before installing, operating
or servicing this equipment. Become familiar with this Owner’s
Manual and with the unit. The generator can operate safely, effi-
ciently and reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to follow simple
and fundamental rules or precautions.
The manufacturer cannot anticipate every possible circumstance
that might involve a hazard. The warnings in this manual, and on
tags and decals affixed to the unit are, therefore, not all inclusive.
If a procedure, work method or operating technique is used that
the manufacturer does not specifically recommend, ensure that it
is safe for others. Also make sure the procedure, work method or
operating technique utilized does not render the generator unsafe.
n
Despite the safe design of this generator,
operating this equipment imprudently, neglect-
ing its maintenance or being careless can cause
possible injury or death. Permit only respon-
sible and capable persons to install, operate or
maintain this equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
n
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.
GENERAL HAZARDS
For safety reasons, the manufacturer recommends that this •
equipment be installed, serviced and repaired by a Service
Dealer or other competent, qualified electrician or installation
technician who is familiar with applicable codes, standards
and regulations. The operator also must comply with all such
codes, standards and regulations.
Installation, operation, servicing and repair of this (and related) •
equipment must always comply with applicable codes, stan-
dards, laws and regulations. Adhere strictly to local, state and
national electrical and building codes. Comply with regulations
the Occupational Safety and Health Administration (OSHA) has
established. Also, ensure that the generator is installed, operat-
ed and serviced in accordance with the manufacturer’s instruc-
tions and recommendations. Following installation, do nothing
that might render the unit unsafe or in noncompliance with the
aforementioned codes, standards, laws and regulations.
The engine exhaust fumes contain carbon monoxide gas, which •
can be DEADLY. This dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness or even death. For
that reason, adequate ventilation must be provided. This should
be considered prior to installing the generator. The unit should
be positioned to direct exhaust gasses safely away from any
building where people, animals, etc., will not be harmed. Any
exhaust stacks that ship loose with the unit must be installed
properly per the manufacturer's instruction, and in strict compli-
ance with applicable codes and standards.
Keep hands, feet, clothing, etc., away from drive belts, fans, •
and other moving or hot parts. Never remove any drive belt or
fan guard while the unit is operating.
Adequate, unobstructed flow of cooling and ventilating air is •
critical in any room or building housing the generator to prevent
buildup of explosive gases and to ensure correct generator
operation. Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seriously affect
safe operation of the generator.
Keep the area around the generator clean and uncluttered. •
Remove any materials that could become hazardous.
When working on this equipment, remain alert at all times. •
Never work on the equipment when physically or mentally
fatigued.
Inspect the generator regularly, and promptly repair or replace •
all worn, damaged or defective parts using only factory-
approved parts.
Before performing any maintenance on the generator, discon-•
nect 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 dan-
gerous operating conditions from leaking exhaust gases, fuel
leakage, oil leakage, etc.
ELECTRICAL HAZARDS
All stationary emergency generators covered by this manual •
produce dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely high and dan-
gerous voltages to the transfer switch as well as the 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 stand-•
ing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
1-2
Safety004 Rev. F 05/10
Safety Instructions

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 con-
nected 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 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 (ampac-
ity) 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 pos-
sibly 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.
Stationary emergency 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 cir-
cuit (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 pos-
sible, 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.
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 generators 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.

EQUIPMENT DESCRIPTION
This equipment is a revolving field, alternating current Stationary
Emergency Generator. It is powered by a gaseous fueled engine
operating at 1800 rpm for 4-pole direct drive units, 3600 rpm for
2-pole direct drive units and 2300 - 3000 rpm for quiet drive gear
units. See the Specifications section for exact numbers. The unit
comes complete with a sound attenuated enclosure, internally
mounted muffler, control console, mainline circuit breaker, bat-
tery charger, and protective alarms as explained in the following
paragraph.
All AC connections, including the power leads from the alterna-
tor, 120 volt battery charger input and control connections to the
transfer switch are available in the main connection box.
The Stationary Emergency Generator incorporates the following
alternator features:
Rotor and Stator insulation class is rated as defined by NEMA •
MG1-32.6, NEMA MG1-1.66. The generator is self ventilated
and drip-proof constructed. Refer to the Specifications section
or the data label for the class ratings.
The voltage waveform deviation, total harmonic content of the •
AC waveform and telephone influence factor have been evalu-
ated and are acceptable according to NEMA MG1-32.
ENGINE OIL RECOMMENDATIONS
The unit has been filled with 5W-20 engine oil at the factory. Use
a high-quality detergent oil classified “For Service SJ or SH.”
Detergent oils keep the engine cleaner and reduce carbon deposits.
When changing the engine oil, be sure to use 5W-30 engine oil.
n
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
NOTE:
If not already equipped, it is strongly recommended to use the
optional Cold Weather Start Kit for temperatures below 32° F.
The part number for the Cold Weather Start Kit can be found
in the Specifications section or by contacting an authorized
dealer. The oil grade for temperatures below 32° F is 5W-30
synthetic oil.
COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol base anti-freeze
and deionized water. Cooling system capacity is listed in the
specifications. Use only deionized water and only low silicate
anti-freeze. If desired, add a high quality rust inhibitor to the rec-
ommended coolant mixture. When adding coolant, always add the
recommended 50-50 mixture.
n
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
mium hydroxide (“green slime”) forms and will
cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding eth-
ylene glycol base anti-freeze. Using any high
silicate anti-freeze boosters or additives will
also cause overheating. The manufacturer also
recommends that any soluble oil inhibitor is
NOT used for this equipment.
n
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
n
Ethylene glycol base antifreeze is poisonous.
Do not use mouth to siphon coolant from the
radiator, recovery bottle or any container. Wash
hands thoroughly after handling. Never store
used antifreeze in an open container because
animals are attracted to the smell and taste of
antifreeze even though it is poisonous to them.

Equipment Description

ENGINE PROTECTIVE DEVICES
The Stationary Emergency 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.
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 infor-
mation.
HIGH COOLANT TEMPERATURE SENDER
An analog coolant temperture sender, located in the engine's
cooling system will cause an engine shutdown if the temperature
should exceed approximately 125° C (257° F). The generator will
automatically restart once the temperature has returned to a safe
operating level.
LOW COOLANT LEVEL SENSOR
To prevent overheating, the engine has a low coolant level sensor.
If the level of engine coolant drops below the level of the low cool-
ant level sensor, the engine automatically shuts down.
LOW OIL PRESSURE SWITCH
This switch has normally closed contacts that are held open by
engine oil pressure during cranking and operating. Should oil pres-
sure 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.
OVERCRANK SHUTDOWN
After a prespecified duration of cranking, this function ends the
cranking if the engine has failed to start. The overcrank message
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.
Approximate Crank Cycle Times
15 seconds ON•
7 seconds OFF•
7 seconds ON•
7 seconds OFF•
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.
RPM SENSOR LOSS SHUTDOWN
If the speed signal to the control panel is lost, engine shutdown
will occur.
DC FUSES
A fuse (7.5 amp) is located on the control panel. It protects the
panel 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.
A fuse (25 amp) is located in the engine wire harness adjacent
to the DC alternator. It is used to prevent circuit failure due to DC
alternator falure. It will also protect the system in the event of a
wiring short-dircuit. If this fuse is blown, the generator will not
operate. Replace these fuses with the same size, type, and rating.

Engine Protective Devices

FUEL SYSTEM
FUEL REQUIREMENTS
The Stationary Emergency Generator may be equipped with one of
the following fuel systems:
• Natural gas fuel system
• Propane vapor (LPV) fuel system
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.
NOTE:
The fuel consumption requirements are identified in the
Specifications section of the Owner's Manual. Refer to the
Installation Manual if assistance is required for the sizing of
the pipe diameter for the generator. Any piping used to connect
the generator to the fuel supply should be of adequate size to
achieve the 100% load fuel consumption requirements identi-
fied in the Specifications section regardless of actual load.
NOTE:
The recommended fuel pressure is identified in the Specifications
section this manual.
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.
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 distribu-
tion 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 must never
exceed approximately 14 inches water column (0.5 psi).
PROPANE VAPOR WITHDRAWAL FUEL SYSTEM
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:
• When ambient temperatures are low and engine fuel consump-
tion 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.

RECONFIGURING THE FUEL
SYSTEM
NOTE:
All models are configured to run on natural gas from the fac-
tory.
Before the generator can be operated using a LP fuel source, the
fuel system and control panel (refer to the installation drawing for
location) must be reconfigured. The steps to reconfigure the gen-
erator from a natural gas (NG) to a liquidified petroleum (LP) fuel
source are as follows:
FUEL SYSTEM
1. Turn the main gas supply off and disconnect the battery.
2. Remove the carburetor fuel hose from the outlet port of the
demand regulator (see Figure 6.1).
3. Disconnect the power wires from the fuel solenoid located
on top of the regulator assembly by removing the screw on
the front of the connector and pulling the connector forward,
away from the solenoid body.
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. The solenoid assembly may need to be
removed before performing this operation (Figure 6.1).
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 pipe onto the outlet
port of the demand regulator. Use pipe sealant on the pipe
threads.
10. Reverse steps 1-4 in this procedure to reactivate the demand
regulator.
11. Follow the instructions in the Control Panel section.
Serious injury, including death, or damage
may occur if not configured properly. Please
consult an Authorized Dealer with any ques-
tions.
Figure 6.1 — Reconfigure the Fuel System
CONTROL PANEL
The FUEL TYPE must be reconfigured in the control panel to final-
ize the conversion process. This generator is configured at the
factory to operate on natural gas. If conversion to LP is required,
please complete the mechanical conversion process and then call
888-9ACTIVATE for the control panel password. This fuel selection
conversion is required to be password protected by Environmental
Protection Agency [EPA] regulations.
Whenever the Generator’s Fuel Regulator is
converted from one Fuel type to the other,
the Control Panel must be reconfigured for
the correct fuel type. Failure to convert both
the Regulator and Control Panel will result in
decreased performance and an increase in
emissions, and is a violation of EPA regula-
tions.

ALTERNATOR AC LEAD
CONNECTIONS
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. The voltage and phase
are described on the generator data label. The number of lead
wires can be identified using the Specifications section and the
power output rating on the generator data label. For example, if
the generator produces 130kW, 277/480 Volt, 3-phase power, the
generator has 12 alternator output leads. Figure 7.3 describes the
stator power winding connection for the generator.

General Information

CONTROL PANEL INTERFACE
USING THE AUTO/OFF/MANUAL SWITCH
With the switch set to AUTO, the engine may
crank and start at any time without warning.
Such automatic starting occurs when utility
power source voltage drops below a preset
level or during the normal exercise cycle. To
prevent possible injury that might be caused
by such sudden starts, always set the switch
to OFF and remove the fuse before work-
ing on or around the generator or transfer
switch. Then, place a “DO NOT OPERATE”
tag on the generator panel and on the trans-
fer switch.
1. “AUTO” Position – Selecting this switch activates fully auto-
matic system operation. It also allows the unit to automati-
cally start and exercise the engine every seven days with the
setting of the exercise timer (see the Setting the Exercise
Timer section).
2. “OFF” Position – This switch position shuts down the engine.
This position also prevents automatic operation.
3. “MANUAL” Position – Set the switch to MANUAL to crank
and start the engine. Transfer to standby power will not occur
unless there is a utility failure.
ACTIVATE THE GENERATOR
When battery power is applied to the generator during the instal-
lation process, the controller will turn ON and the LCD screen will
illuminate. However, the generator still needs to be activated before
it will automatically run in the event of a power outage.
Activating the generator is a simple one time process that is guided
by the controller screen prompts. Once the product is activated,
the controller screen will not prompt you again, even if you discon-
nect the generator battery.
To obtain the activation code, record the generator serial number
and log onto www.activategen.com or call 1-888-9ACTIVATE and
follow the steps to retrieve the activation code.
After obtaining your activation code, please complete the following
steps at the generator’s control panel in the Activation Chart on the
following page.
NOTE:
The generator will only run in manual until the passcode has
been entered.
Upon power up, this controller will go through a system self test
which will check for the presence of utility voltage on the DC
circuits. This is done to prevent damage if the installer mistakenly
connects AC utility power sense wires into the DC terminal block.
If utility voltage is detected, the controller will display a warning
message and lock out the generator, preventing damage to the
controller. Power to the controller must be removed to clear this
warning.
Utility voltage must be turned on and present at the N1 and N2
terminals inside the generator control panel for this test to be
performed and pass.
NOTE:
DAMAGE CAUSED BY MISWIRING OF THE INTERCONNECT
WIRES IS NOT WARRANTABLE!
This test will be performed each time the controller is powered
up.
Next, the user must enter the minimum settings to operate. These
settings are current date and time and exercise day and time. The
maintenance intervals will be initialized (i.e. started) the first time
the clock is set. If the clock is never set at power up, the mainte-
nance intervals will be reset every time power is applied.
If a subsequent power loss (loss of battery power) occurs the
Installation assistant will operate upon power restoration. The self
test routine will be run and then the customer will be required to
re-enter the time and date, as this is not retained during a power
loss. The unit will not require re-activation.
DISPLAY INTERFACE MENUS
The LCD display is organized as detailed below:
• The “Home” page, this page is the default page which will be
displayed if no keys are pressed for 30 seconds. This page
normally shows the current Status message and the current
date and time. The highest priority active Alarm and/or Warning
will be automatically posted on this page as well as flashing
the backlight when such an event is detected. In the case of
multiple Alarms or Warnings, only the first message will be
displayed. To clear an Alarm or Warning, see the Protection
Systems section - Clear Alarm.
• The display backlight is normally off. If the user presses any
key, the backlight will come on automatically and remain on for
30 seconds after the last key was pressed.
• The “Main Menu” page will allow the user to navigate to all other
pages or sub-menus by using the Left/Right and Enter keys.
This page can be accessed at any time with several presses of
the dedicated Escape key. Each press of the Escape key takes
you back to the previous menu until the main menu is reached.
This page displays the following options: HISTORY; STATUS;
EDIT; AND DEBUG. (See the Appendix - "Menu System".)

NOTE:
DAMAGE CAUSED BY MISWIRING OF THE INTERCONNECT
WIRES IS NOT WARRANTABLE!
This test will be performed each time the controller is powered
up.
Upon first power up of the generator, the display interface will
begin an installation assistant. The assistant will prompt the user
to set the minimum settings to operate. These settings are simply:
Current Date/Time and Exercise Day/Time. The maintenance inter-
vals will be initialized when the exercise time is entered.
The exercise settings can be changed at any time via the "EDIT"
menu (see Appendix, "Menu System").
If the 12 volt battery is disconnected or the fuse removed, the
Installation Assistant will operate upon power restoration. The
only difference is the display will only prompt the customer for the
current Time and Date.
IF THE INSTALLER TESTS THE GENERATOR PRIOR TO
INSTALLATION, PRESS THE “ENTER” KEY TO AVOID SETTING
UP THE EXERCISE TIME. THIS WILL ENSURE THAT WHEN
THE CUSTOMER POWERS UP THE UNIT, HE WILL STILL BE
PROMPTED TO ENTER AN EXERCISE TIME.
SETTING THE EXERCISE TIMER
This generator is equipped with an exercise timer. Once it is set,
the generator will start and exercise every seven days, on the day
of the week and at the time of day specified. During this exercise
period, the unit runs for approximately 12 minutes and then shuts
down. Transfer of loads to the generator output does not occur
during the exercise cycle unless utility power is lost.
LOW SPEED EXERCISE
The standard start sequence will be initiated.
• All 1800 rpm units will exercise at 1400 RPM
• All 3600 rpm units will exercise at 1800 RPM
If utility is lost during exercise the controller will do the following:
• Wait for the “line interrupt period” for utility to return. If utility
returns within the “line interrupt period”, continue to exercise
at low RPM.
• If utility is still lost after the “line interrupt period”, run the engine
up to normal RPM and transfer the load. At this time the con-
troller will exit the exercise routine and assume full automatic
operation.

FUEL CONVERSION
For fuel conversion steps, refer to the GenSpec section,
RECONFIGURING THE FUEL SYSTEM.
OPERATION
This system is intended to supply standby power in the event of a
utility failure. The control system will monitor the utility voltage to
determine if stand-by power is required. Should the utility voltage
fail, the generator will start and run normally, detaching from the
utility and supplying the customer load from the generator. When
utility power returns, the controller will re-transfer the customer
load back to utility and shut down the generator.
AUTOMATIC TRANSFER OPERATION
To select automatic operation, do the following:
1. Make sure the transfer switch main contacts are set to their
UTILITY position, i.e., loads connected to the utility power
source.
2. Be sure that normal UTILITY power source voltage is avail-
able to transfer switch terminal lugs N1 and N2 (Refer to the
Electrical Data section).
3. Set the generator’s AUTO/OFF/MANUAL switch to AUTO.
4. Set the generator’s main circuit breaker to its ON (or CLOSED)
position.
With the preceding steps complete, the generator will start auto-
matically when utility source voltage drops below a preset level.
After the unit starts, loads are transferred to the standby power
source. Refer to the Sequence of Automatic Operation section.
8-3
CntrlNexus001 Rev. D 04/11
Control Panel

SEQUENCE OF AUTOMATIC OPERATION
Initial Conditions: Generator in Auto ready to run, load being sup-
plied by the Utility Source through the transfer switch.
1. When the utility voltage fails (falls below 60% of nominal), a
10-30 second (programmable) “line interrupt” delay timer is
started. The factory set time delay is 10 seconds. If at the
end of the line interrupt time the utility voltage is above 60%
the engine will not crank. If the utility voltage is still below
the 60% of nominal at the end of the line interrupt time, the
unit will crank and start. If the unit cranks for more than 10
seconds and the utility voltage rises above 80% of nominal
(programmed pickup voltage) and the unit has not started, the
crank cycle will abort.
2. As soon as the unit starts a 5 second “warm-up” timer is initi-
ated. When the warm-up timer expires the control will transfer
the load to the generator (through the RTS switch) if the utility
voltage is less than 80% of nominal. If the utility voltage is
greater than the 80% of nominal at the end of the warm-up
time the load will not be transferred to the generator and a one
minute low-speed cool down period will start. At the end of
the one minute cool down period the generator will stop.
3. Once the unit is running and the switch has transferred the
load to the generator the unit will monitor utility voltage.
When utility voltage returns (above the programmable pickup
voltage, normally 80% of nominal), a 15 second “Return to
Utility” timer will start. At the end of the return to utility time,
if the utility voltage is still above the pickup voltage, the unit
will transfer the load back to the utility source and run the unit
through a one minute cool down period. When the cool down
period is over the unit will shut down and be ready for the next
outage.
4. If during the cool down period utility voltage should fall below
60% of nominal the 5 second warm-up timer is initiated and
the unit will transfer the load back to the generator and con-
tinue to monitor the utility.
CRANK CYCLES AND OVERCRANK SHUTDOWN
If the unit fails to start during a cranking period it will display the
Overcrank Shutdown Alarm. The system will control the cranking
cycles as follows:
The first crank cycle is a 16 second crank time followed by a 7
second rest. The next 5 cycles will be 7 seconds of cranking time
each followed by a 7 second rest time.
If the unit fails to start by the end of the 6 crank/rest cycles
the Overcrank Shutdown Alarm will display and the unit will not
attempt to crank until the alarm is reset.
AUTO START
This unit is designed to automatically start in the event of a util-
ity failure or brown out condition. Brown out is defined as utility
voltage less than 60% nominal, while utility is considered good
when it is restored to at least the pickup value, 80% of nominal.
These levels are fixed. The “Line Interrupt period” is an adjustable
parameter by the dealer. If 2-wire start mode is activated, the unit
will start when 2-wire start is active.
MANUAL START
Allows the user to start and run the generator manually.
Transfer of the load to the generator will occur if utility is lost while
the unit is running in the manual mode (only if activated).
ALARM AND WARNING MESSAGES
Alarms are defined as “Latching” which means they must be
cleared before the alarm message on the screen will clear. They
can be of type “Shutdown” or not and are logged in the alarm log.
Alarms are all annunciated on the display).
Warnings are “Non Latching” meaning the message automati-
cally clears when the warning condition goes away. Warnings can
not be of type “Shutdown” but they are logged in the alarm log.
Warnings are all annunciated on the display.
LOW OIL PRESSURE SHUTDOWN ALARM
There is a 10 second delay before oil pressure is monitored.
HIGH COOLANT TEMPERATURE SHUTDOWN ALARM
There is a 10 second delay before engine temperature is moni-
tored.
Once running there is a 1/4 second delay before shut down. The
limit is set at 125° C or 257° F.
OVERCRANK SHUTDOWN ALARM
Occurs if the engine has not started within the specified crank
cycle.
OVERSPEED SHUTDOWN ALARM
Warning indicator is measured and calculated by the microproces-
sor. Overspeed is defined as +20% of nominal engine speed for 3
seconds, or +25% immediate.
Nominal engine speed = 60.0 Hz
RPM SENSOR FAILURE SHUTDOWN ALARM
During cranking: If the board does not see a valid RPM signal
within four (4) seconds of cranking it will shut down and lock out
on RPM sensor loss.
During running: If the RPM signal is lost for one full second the
board will shut the engine down, wait 15 seconds, then re-crank
the engine if in AUTO, it will not re-crank in MANUAL.
If no RPM signal is detected within the first four (4) seconds of
cranking, the control board will shut the engine down and latch out
on RPM sensor loss.
If the RPM signal is detected the engine will start and run normally.
If the RPM signal is subsequently lost the control board will try
two more re-cranks before latching out and flashing the RPM
Sensor Failure message (if it is in AUTO).

CHECK ENGINE MESSAGE
The control system has detected an emissions related fault. This
fault cannot be cleared using the control panel interface. The unit
will continue to operate in automatic mode. Contact your local
servicing dealer.
UNDER-FREQUENCY SHUTDOWN ALARM
After starting, if the generator stays under frequency for more than
30 seconds, it will shutdown.
LOW BATTERY ALARM
While running, if the average battery voltage falls below 11.9 volts
for one (1) minute, the low battery alarm will be displayed.
LOW BATTERY WARNING
The microprocessor will continually monitor the battery voltage
and display the Low Battery Voltage message if the battery voltage
falls below 12.2 Volts for one (1) minute.
No other action is taken on a low battery warning condition. The
warning will automatically clear if the battery voltage rises above
12.2 volts.
NOTE:
The battery sentinel is a separate feature that monitors battery
condition.
LOW COOLANT LEVEL ALARM
This is a shutdown alarm. The sensor will be continuously moni-
tored. If an error condition is seen for five (5) consecutive sec-
onds, the alarm will be displayed.
MISSING CAM PULSE ALARM
This is a shutdown alarm. The alarm will activate after five (5)
seconds of continuously missing cam pulses.
MISSING CRANK PULSE ALARM
This is a shutdown alarm. The alarm will activate after 12 con-
secutive revs where crank pulses are missing.
LOW FUEL PRESSURE WARNING
Fuel pressure is monitored by a digital sensor with a fixed setpoint
of below five (5) inches water column.
GOVERNOR SENSOR FAULT ALARM
The governor position is monitored by an analog feedback signal. If
the throttle position is seen outside of the normal operating range,
a shutdown alarm is displayed. If the throttle is commanded to
move, and no movement is seen, a shutdown alarm is displayed.
WIRING ERROR ALARM
When power is first apllied to the contoller, the software will per-
form a check on the wiring of the transfer output, and ensure it
does not have high voltage on the wire. If this is the case, it will
signal a miswire alarm and will not run. The test can be skipped
by use of the escape key.
UNDERVOLTAGE ALARM
If the generator voltage falls below 60% for >5 seconds, an alarm
will be issued.

INTERNAL FAILURE SHUTDOWN ALARM
Any internal failure that can be detected such as corrupted
firmware will cause this shutdown alarm. This alarm cannot be
cleared.
CANBUS ALARM
Where applicable, if the Canbus communications link fails to com-
municate, a “Canbus Alarm” will be generated. This only applies
to systems with external ignition modules. The alarm may be
generated if:
1. The physical link is broken.
2. The Ignition Module fails or resets.
3. The Nexus Controller fails or resets.
4. Having the Battery Chargers 120 VAC connected without a
battery installed.
5. A blown 10 amp Ignition Module fuse (approximately 12

CHANGING ENGINE OIL
n
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeat-
ed skin exposure with used oil. Thoroughly
wash exposed areas with soap.
Refer to the Service Schedule for engine oil and filter change fre-
quencies.
Drain the oil while the engine is still warm from running. This
means warm up the engine, shut it down and drain immediately
as follows:
1. Remove the drain hose from its retaining clip or cut the zip-tie
securing the oil drain hose.
2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil com-
pletely into suitable container.
3. When all oil has drained, install and tighten OIL DRAIN HOSE
CAP and secure drain hose with a new zip-tie, or place the
hose in its retaining clip.
4. Turn OIL FILTER (Figure 10.1) counterclockwise and remove.
Properly dispose of old filter.
5. Apply light coating of new engine oil to seal of new oil fil-
ter. Install FILTER and tighten by hand only. DO NOT OVER
TIGHTEN.
6. Remove OIL FILL CAP and add recommended oil. Crankcase
oil capacity is listed in the "Specifications" section.
n
After refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK “ADD”
MARK.
7. Start engine and check for oil leaks.
8. Shut OFF engine and wait 10 minutes for the oil to settle down
into the oil pan. Recheck oil level on dipstick. DO NOT fill
above the dipstick "FULL" mark.
9. Dispose of used oil at a proper collection center.
COOLING INTAKE/OUTLET
Air intake and outlet openings in the generator compartment must
be open and unobstructed for continued proper operation. This
includes such obstructions as high grass, weeds, brush, leaves
and snow.
Without sufficient cooling and ventilating air flow, the engine/gen-
erator quickly overheats, which causes it to shut down. (See the
installation diagram.)
The exhaust system parts from this product get
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc. must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
INSPECT COOLING SYSTEM
Inspect engine cooling system. See the Service Schedule.•
Check hoses for damage, deterioration, leaks, etc. Correct any •
discrepancies found.
Check hose clamps for tightness.•
10-1
Maint028 Rev. A 05/10
Maintenance

ENGINE COOLANT
Check coolant level in coolant recovery bottle. See the Specifications
and Service Schedule sections.
Add recommended coolant mixture as necessary.•
Periodically remove radiator pressure cap (only when engine •
has cooled down) to make sure the coolant recovery system
is functioning properly. Coolant should be at bottom of radia-
tor filler neck. If coolant level is low, inspect gasket in radiator
pressure cap. Replace cap, if necessary. To have pressure cap
tested, contact a Service Facility. Inspect cooling system and
coolant recovery system for leaks.
COOLANT CHANGE
Every year, have a service facility drain, flush and refill the cooling
system. See the Specifications and Service Schedule for cooling
system recommendations.
OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL
SYSTEM
Engine cranking, start up and running are controlled by a solid
state Engine Controller circuit board. Battery voltage is delivered
to that circuit board via the control panel fuse. This overcurrent
protection device will open if the circuit is overloaded.
n
If a circuit breaker opens or a fuse element
melts, find the cause of the overload before
resetting the circuit breaker or replacing the
fuse.
EXERCISE SYSTEM
Starts the Stationary Emergency Generator engine once every
seven days and lets it run for 12 minutes.
PERFORM VISUAL INSPECTION
Complete a thorough visual inspection of the entire engine-genera-
tor monthly. Look for obvious damage, loose, missing or corroded
nuts, bolts and other fasteners. Look for fuel, oil or coolant leaks.
INSPECT EXHAUST SYSTEM
Inspect the exhaust system at least once every year. Check all
exhaust system pipes, mufflers, clamps, etc. for condition, tight-
ness, leaks, security, damage.
CHECK FAN BELT
Inspect fan belts every year. Replace any damaged, deterio-•
rated, worn or otherwise defective belt.
Check fan belt tension. Thumb pressure, exerted midway •
between pulleys, should deflect about 3/8 to 5/8 of an inch.
This system uses an automatic belt tensioner and cannot be
adjusted.
INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
n
Do not attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. Excessively high operating speeds
are dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by
incorrect frequency and/or voltage. Only quali-
fied service technicians should adjust the gov-
erned speed.
CHANGING THE ENGINE AIR FILTER
To replace the engine air filter, remove the air filter cover and
replace the air filter making sure it is positioned properly before
reattaching the cover (Figure 10.2).
See the Service Schedule for air filter maintenance.

Maintenance

SPARK PLUGS
Reset the spark plug gap or replace the spark plugs as neces-
sary.
1. Clean the area around the base of the spark plugs to keep dirt
and debris out of the engine. Clean by scraping or washing
using a wire brush and commercial solvent. Do not blast the
spark plugs to clean.
2. Remove the spark plugs and check the condition. Replace
the spark plugs if worn or if reuse is questionable. See the
“Service Schedule” section for recommended inspection.
3. Check the spark plug gap using a wire feeler gauge. See the
Specifications section for the required spark plug gap.
CAM SENSOR
Visually inspect Cam Sensor position. Cam sensor should be set
in full counter-clockwise position up against the retaining washer.
(Figure 10.3).

BATTERY MAINTENANCE
The battery should be inspected per the Service Schedule section.
The following procedure should be followed for inspection:
1. Inspect the battery posts and cables for tightness and corro-
sion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries and, if
necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP
WATER IN BATTERIES.
3. Have the state of charge and condition checked. This should
be done with an automotive-type battery hydrometer.
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after
charging. The slightest spark can ignite the gas
and cause an explosion. Such an explosion can
shatter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
n
Battery electrolyte fluid is an extremely corro-
sive sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
n
Do not use any jumper cables or booster bat-
tery to crank and start the generator engine. If
the battery has completely discharged, remove
it from the generator for recharging.
n
Be sure the AUTO/OFF/MANUAL switch is set
to the OFF position, before connecting the
battery cables. If the switch is set to AUTO or
MANUAL, the generator can crank and start as
soon as the battery cables are connected.
Be sure the 120VAC power supply to the battery
is turned OFF, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
BATTERY REPLACEMENT
NOTE:
Unit DOES NOT include battery.
When supplying or replacing the battery, the recommended num-
ber and type of battery is listed in the Specifications Section.
NOTE:
The BCI number should be located directly on the battery.
BATTERY FLUID
Check battery electrolyte fluid based on the Service Schedule.
Fluid should cover separators in all battery cells. If fluid level is
low, add distilled water to cover tops of separators. DO NOT USE
TAP WATER IN BATTERY.
CLEANING THE STATIONARY EMERGENCY 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 a
Service Dealer. That dealer will use dry, low pressure air to clean
internal windings.
Finally, have the insulation resistance of stator and rotor windings
checked. If insulation resistances are excessively low, the genera-
tor may require drying.
