Safety Rules

2

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

using a procedure, work method or operating technique the manu-

facturer 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.



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

responsible and capable persons to install,

operate and 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.



Parts of the generator are rotating and/or

hot during operation. Exercise care near run-

ning generators.



Installation must always comply with appli-

cable codes, standards, laws and regula-

tions.



A running generator gives off carbon mon-

oxide, and odorless, colorless poison gas.

Breathing in carbon monoxide can cause

headaches, fatigue, diziness, nausea, vomit-

ting, confusion, fainting, siezures or death.

GENERAL HAZARDS

• For safety reasons, the manufacturer recommends that this equip-

ment 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.

• The engine exhaust fumes contain carbon monoxide, which

can be DEADLY. This dangerous gas, if breathed in sufficient

concentrations, can cause unconsciousness or even death.

Do NOT alter or add to the exhaust system or do anything that

might render the system unsafe or in noncompliance with appli-

cable codes and standards.

• Install a battery operated carbon monoxide alarm indoors,

according to manufacturer's instructions/recommendations.

• Adequate, unobstructed flow of cooling and ventilating air is

critical to correct generator operation. Do not alter the instal-

lation or permit even partial blockage of ventilation provisions,

as this can seriously affect safe operation of the generator. The

generator MUST be installed and operated outdoors only.

• 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.

• 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 contact the nearest Dealer

for parts needing repair or replacement.

• 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, then remove the POSITIVE, POS or (+) cable. When

reconnecting the cables, connect the POSITIVE cable first, the

NEGATIVE 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.

EXHAUST HAZARDS

• Generator engine exhaust contains DEADLY carbon monox-

ide, an odorless, colorless poisonous gas. Breathing carbon

monoxide can cause: dizziness, throbbing temples, nausea,

muscular twitching, headache, vomiting, weakness and sleepi-

ness, inability to think clearly, fainting, unconsciousness or

even death. If you experience any carbon monoxide poisoning

symptoms, move into fresh air and immediately seek medical

attention.

• NEVER operate the generator set inside any garage or other

enclosed area EVEN IF the doors and windows are open.

ELECTRICAL HAZARDS

• All generators covered by this manual produce dangerous elec-

trical voltages and can cause fatal electrical shock. Utility power

delivers extremely high and dangerous voltages to the transfer

switch as does the standby generator when it is in operation.

Avoid contact with bare wires, terminals, connections, etc.,

while the unit is running. Ensure all appropriate covers, guards

and barriers are in place, secured and/or locked before operat-

ing 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.



SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted near the unit’s

installation site. Safety should be stressed to all operators and potential operators of this equipment.

Safety Rules

3

• The National Electrical Code (NEC) requires the frame and external

electrically conductive parts of the generator to be connected to

an approved earth ground. Local electrical codes also may require

proper grounding of the generator electrical system.

• After installing this home standby electrical system, the genera-

tor may crank and start at any time without warning. When this

occurs, load circuits are transferred to the STANDBY (genera-

tor) power source. To prevent possible injury if such a start and

transfer occur, always set the generator’s AUTO/OFF/MANUAL

switch to its OFF position before working on equipment and

remove the 7.5A fuse from the generator control panel.

• 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.

FIRE HAZARDS

• For fire safety, the generator must be installed and maintained

properly. Installation must always comply with applicable

codes, standards, 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 in accordance with the manufacturer’s

instructions and recommendations. Following proper installa-

tion, do nothing that might alter a safe installation and render

the unit in noncompliance with the aforementioned codes,

standards, laws and regulations.

• Keep a fire extinguisher near the generator at all times.

Extinguishers rated “ABC” by the National Fire Protection

Association are appropriate for use on the standby electric

system. Keep the extinguisher properly charged and be familiar

with its use. Consult the local fire department with any ques-

tions pertaining to fire extinguishers.

EXPLOSION HAZARDS

• 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.

• Gaseous fluids such as natural gas and liquid propane (LP)

gas are extremely EXPLOSIVE. Install the fuel supply system

according to applicable fuel-gas codes. Before placing the

home standby electric system into service, fuel system lines

must be properly purged and leak tested according to applica-

ble code. After installation, inspect the fuel system periodically

for leaks. No leakage is permitted.

Safety Rules



Only qualified electricians or contractors

should attempt such installations, which must

comply strictly with applicable codes, stan-

dards and regulations.

1.1 UNPACKING/INSPECTION

After unpacking, carefully inspect the contents for damage.

• This standby generator set is ready for installation with a factory

supplied and pre-mounted base pad and has a weather protec-

tive enclosure that is intended for outdoor installation only.

• This UL listed standby generator set may be packaged with an

automatic transfer switch with built in load center. The combi-

nation transfer switch and load center is pre-wired with a two

foot and 30 foot conduit. Circuit breakers for emergency circuit

connections are included (if equipped).

• This UL listed, 2-pole switch is rated at 100 or 200 AC amperes

at 250 volts maximum. The 100 Amp transfer switch is for

indoor use only. The 200 Amp transfer switch is for indoor/

outdoor use (if equipped).



If this generator is used to power electrical load

circuits normally powered by a utility power

source, it is required by code to install a trans-

fer switch. The transfer switch must effectively

isolate the electrical system from the utility

distribution system when the generator is oper-

ating (NEC 700, 701 & 702). Failure to isolate an

electrical system by such means will result in

damage to the generator and also may result in

injury or death to utility power workers due to

backfeed of electrical energy.

If any loss or damage is noted at time of delivery, have the

person(s) making the delivery note all damage on the freight bill

or affix their signature under the consignor's memo of loss or

damage.

If a loss or damage is noted after delivery, separate the damaged

materials and contact the carrier for claim procedures.

“Concealed damage” is understood to mean damage to the con-

tents of a package that is not in evidence at the time of delivery,

but is discovered later.

To properly open the roof, press down on the center top lip and

release the latch. If pressure is not applied from the top, the roof

may appear stuck. Always verify that the side lock is unlocked

before attempting to lift the roof.

1.2 PROTECTION SYSTEMS

Unlike an automobile engine, the generator may have to run for

long periods of time with no operator present to monitor engine

conditions. For that reason, the engine is equipped with the fol-

lowing systems that protect it against potentially damaging condi-

tions:

1. Low Oil Pressure Sensor 6. Low Battery

2. High Temperature Sensor 7. Under-frequency

3. Overcrank 8. Undervoltage

4. Overspeed 9. Overvoltage

5. RPM Sensor 10. Internal Failure

There are readouts on the control panel to notify personnel that

one of these failures has occurred. There is a Status message on

the display that displays when all of the conditions described in the

"Ready to Run" section are true.

1.3 NEC REQUIREMENT

FOR ARC FAULT CIRCUIT

INTERRUPTION BREAKER

FOR BEDROOMS

In 2001, the National Electric Code (NEC) introduced a requirement

for new construction. This new requirement indicates the need for

Arc Fault Circuit Interrupters to be used to protect the complete

branch circuit that feeds a dwelling bedroom. The actual NEC

requirement is indicated below.

1.3.1 SECTION 210.12 ARC FAULT CIRCUIT

INTERRUPTER PROTECTION

1. Definition: An arc fault circuit interrupter is a device intended

to provide protection from the effects of arc faults by recog-

nizing characteristics unique to arcing and by functioning to

de-energize the circuit when an arc fault is detected.

2. Dwelling Unit Bedrooms: All branch circuits that supply 125

volt, single-phase, 15 and 20 ampere outlets installed in

dwelling unit bedrooms shall be protected by an arc fault cir-

cuit interrupter listed to provide protection of the entire branch

circuit.

Section 210.12 requires that AFCI protection be provided on branch

circuits that supply outlets (receptacle, lighting, etc.) in dwell-

ing bedrooms. The requirement is limited to 15 and 20 ampere,

125 volt circuits. There is no prohibition against providing AFCI

protection on other circuits or in locations other than bedrooms.

Because circuits are often shared between a bedroom and other

areas such as closets and hallways, providing AFCI protection on

the complete circuit would comply with 210.12.

4

General Information

5

If during the installation of the home standby system the decision

is made to provide back up power to a bedroom branch circuit,

then the circuit breaker in the transfer switch should be replaced

with an Arc Fault Circuit Interrupter.

It is most important that breakers only be switched like for like.

For instance, if replacing a 15A breaker, it MUST be replaced with

a 15A AFCI breaker. Likewise, a 20A breaker MUST be replaced

with a 20A AFCI.

These AFCI breakers are available at the nearest hardware store.

General Information

1.7 READY TO RUN

The "Ready to Run" on the display is ready when all of the following

conditions are true:

1. The AUTO/OFF/MANUAL switch is set to the AUTO position.

2. The utility voltage being supplied to the unit is being sensed

by the PCB. If the utility sense voltage is not connected to the

unit or if it is below approximately 150-160 volts AC, then

the system will display the message "No Utility Present". This

indicates that if the AUTO/OFF/MANUAL switch is placed in

the Auto position, the generator will start.

3. No alarms are present, for example, low oil pressure, high

temperature, etc.

1.8 FUEL REQUIREMENTS AND

RECOMMENDATIONS

With LP gas, use only the vapor withdrawal system. This type of

system uses the vapors formed above the liquid fuel in the storage

tank.

The engine has been fitted with a fuel carburetion system that

meets the specifications of the 1997 California Air Resources

Board for tamper-proof dual fuel systems. The unit will run on

natural gas or LP gas, but it has been factory set to run on natural

gas. Should the primary fuel need to be changed to LP gas, the

fuel system needs to be reconfigured. See the reconfiguring the

Fuel System section for instructions on reconfiguration of the fuel

system.

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 five (5) inches to seven

(7) inches water column (0.18 to 0.25 psi); and for liquid pro-

pane, 10 inches to 12 inches of water column (0.36 to 0.43 psi).

The primary regulator for the propane supply is NOT INCLUDED

with the generator.

NOTE:

All pipe sizing, construction and layout must comply with NFPA

54 for natural gas applications and NFPA 58 for liquid propane

applications. Once the generator is installed, verify that the fuel

pressure NEVER drops more than one (1) inch water column

from no load to full load from the starting pressure for either

fuel type, and remains within the limits of the stated specifica-

tion.

Prior to installation of the generator, the installer should consult

local fuel suppliers or the fire marshal to check codes and regula-

tions for proper installation. Local codes will mandate correct rout-

ing of gaseous fuel line piping around gardens, shrubs and other

landscaping to prevent any damage.

Special considerations should be given when installing the unit

where local conditions include flooding, tornados, hurricanes,

earthquakes and unstable ground for the flexibility and strength of

piping and their connections.

Use an approved pipe sealant or joint compound on all threaded

fittings.

All installed gaseous fuel piping must be purged and leak tested

prior to initial start-up in accordance with local codes, standards

and regulations.



Gaseous fuels such as natural gas and liquid

propane (LP) gas are highly explosive. Even

the slightest spark can ignite such fuels and

cause an explosion. No leakage of fuel is

permitted. Natural gas, which is lighter than

air, tends to collect in high areas. LP gas is

heavier than air and tends to settle in low

areas.

NOTE:

A minimum of one approved manual shut-off valve must be

installed in the gaseous fuel supply line. The valve must be eas-

ily accessible. Local codes determine the proper location.

1.11 HIGH ALTITUDE OPERATION

The fuel system on this generator may be influenced by operation

at higher altitudes. Proper operation can be ensured by installing

an altitude kit when required. See the table below to determine

when an altitude kit is required. Operating this generator without

the proper altitude kit installed may increase the engine’s emis-

sions and decrease fuel economy and performance. Kits may be

obtained from any Dealer, and should be installed by a qualified

individual.

1.12 LOCATION



The engine exhaust fumes contain carbon

monoxide, which can be DEADLY. This dan-

gerous gas, if breathed in sufficient con-

centrations, can cause unconsciousness or

even death. This generator must be installed

properly, in strict compliance with applicable

codes and standards. Following installation,

do nothing that might render the system

unsafe or in noncompliance with such codes

and standards.

Operate the generator outdoors ONLY.

• Keep exhaust gases from entering a confined

area through windows, doors, ventilation, crawl

spaces or other openings (Figure 1.9).

• It is highly recommended that carbon monox-

ide detector(s) be installed indoors according

to the manufacturer's instructions/recommen-

dations.

• The generator must be mounted safely per

applicable codes and the manufacturer's speci-

fications. Do NOT alter or add to the exhaust

system, or do anything that might render the

exhaust system unsafe or in noncompliance

with applicable codes and standards.

1.12.1 GENERATOR

Install the generator set, in its protective enclosure, outdoors,

where adequate cooling and ventilating air is always available

(Figure 1.9). Consider these factors:

• The installation of the generator must comply strictly with

NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards.

• Install the unit where air inlet and outlet openings will not

become obstructed by leaves, grass, snow, etc.. If prevailing

winds will cause blowing or drifting, consider using a wind-

break to protect the unit.

• Install the generator on high ground where water levels will not

rise and endanger it.

General Information

11

• Allow sufficient room on all sides of the generator for mainte-

nance and servicing. This unit must be installed in accordance

with current applicable NFPA 37 and NFPA 70 standards; as

well as any other federal, state and local codes for minimum

distances from other structures. DO NOT install under wooden

decks or structures unless there is at least five (5) feet of clear-

ance above the generator, three (3) feet of clearance on sides

and front, and 18 inches of clearance at back of unit.

• Install the unit where rain gutter down spouts, roof run-off,

landscape irrigation, water sprinklers or sump pump discharge

does not flood the unit or spray the enclosure, including any air

inlet or outlet openings.

• Install the unit where services will not be affected or obstructed,

including concealed, underground or covered services such as

electrical, fuel, phone, air conditioning or irrigation.

• Where strong prevailing winds blow from one direction, face the

generator air inlet openings to the prevailing winds.

• Install the generator as close as possible to the fuel supply, to

reduce the length of piping.

• Install the generator as close as possible to the transfer switch.

REMEMBER THAT LAWS OR CODES MAY REGULATE THE

DISTANCE AND LOCATION.

• The genset must be installed on a level surface. The base frame

must be level within two (2) inches all around.

• The generator is typically placed on pea gravel or crushed

stone. Check local codes if a concrete slab is required. If a

concrete base slab is required, all federal, state and local codes

should be followed. Special attention should be given to the

concrete base slab which should exceed the length and width

of the generator by a minimum of six (6) inches (0.152 meters)

on all sides.

Figure 1.9 – Generator Clearances

1.12.2 INSTALLATION GUIDELINES FOR STATIONARY

STATIONARY AIR-COOLED 8 - 20KW

GENERATORS

The National Fire Protection Association has a standard for the

installation and use of stationary combustion engines. That

standard is NFPA 37 and its requirements limit the spacing of an

enclosed generator set from a structure or wall (Figure 1.10).

NFPA 37, Section 4.1.4, Engines Located Outdoors. Engines, and

their weatherproof housings if provided, that are installed outdoors

shall be located at least 5 ft. from openings in walls and at least 5

ft. from structures having combustible walls. A minimum separa-

tion shall not be required where the following conditions exist:

1. The adjacent wall of the structure has a fire resistance rating

of at least 1 hour.

2. The weatherproof enclosure is constructed of noncombus-

tible materials and it has been demonstrated that a fire within

the enclosure will not ignite combustible materials outside the

enclosure.

Annex A — Explanatory Material

A4.1.4 (2) Means of demonstrating compliance are by means

of full scale fire test or by calculation procedures.

Because of the limited spaces that are frequently available for

installation, it has become apparent that exception (2) would be

beneficial for many residential and commercial installations. With

that in mind, the manufacturer contracted with an independent

testing laboratory to run full scale fire tests to assure that the

enclosure will not ignite combustible materials outside the enclo-

sure.

The criteria was to determine the worst case fire scenario within

the generator and to determine the ignitability of items outside the

engine enclosure at various distances. The enclosure is construct-

ed of non-combustible materials and the results and conclusions

from the independent testing lab indicated that any fire within the

generator enclosure would not pose any ignition risk to nearby

combustibles or structures, with or without fire service personnel

response.

Based on this testing and the requirements of NFPA 37, Sec 4.1.4,

the guidelines for installation of the generators listed above are

changed to 18 inches (457mm) from the back side of the genera-

tor to a stationary wall or building. For adequate maintenance and

airflow clearance, the area above the generator should be at least

4 feet with a minimum of 3 feet at the front and ends of the enclo-

sure. This would include trees, shrubs and vegetation that could

obstruct airflow. See the diagram on the reverse of this page and

the installation drawing within the owner’s manual for details.

Generator exhaust contains DEADLY carbon monoxide gas. This

dangerous gas can cause unconsciousness or death. Do not place

the unit near windows, doors, fresh air intakes (furnaces, etc.) or

any openings in the building or structure, including windows and

doors of an attached garage.



If the AUTO/OFF/MANUAL switch is not set

to its OFF position, the generator can crank

and start as soon as the battery cables are

connected. If the utility power supply is not

turned off, sparking can occur at the battery

posts and cause an explosion.

1.13 BATTERY REQUIREMENTS

See the Specifications section for correct battery size and rating.

1.14 BATTERY INSTALLATION

Fill the battery with the proper electrolyte fluid if necessary and

have the battery fully charged before installing it.

Before installing and connecting the battery, complete the follow-

ing steps:

1. Set the generator's AUTO/OFF/MANUAL switch to OFF.

2. Turn off utility power supply to the transfer switch.

3. Remove the 7.5A fuse from the generator control panel.

Battery cables were factory connected at the generator (Figure

1.11). Connect cables to battery posts as follows:

4. Connect the red battery cable (from starter contactor) to the

battery post indicated by a positive, POS or (+).

5. Connect the black battery cable (from frame ground) to the

battery post indicated by a negative, NEG or (—).

6. Install the battery post covers (included).

NOTE:

Dielectric grease should be used on battery posts to aid in the

prevention of corrosion.

NOTE:

Damage will result if battery connections are made in reverse.

Figure 1.11 – Battery Cable Connections

NOTE:

In areas where temperatures regularly fall below 32° F (0° C) it

is recommended that a pad type battery heater be installed to

aid in cold climate starting.

1.15 THE BATTERY





DO NOT dispose of the battery in a fire. The

battery is capable of exploding.



A battery presents a risk of electrical shock

and high short circuit current. The following

precautions are to be observed when work-

ing on batteries:

• Remove the 7.5A fuse from the generator con-

trol panel.

• Remove watches, rings or other metal objects.

• Use tools with insulated handles.

• Wear rubber gloves and boots.

• Do not lay tools or metal parts on top of the

battery.

• Disconnect charging source prior to connecting

or disconnecting battery terminals.



Do not open or mutilate the battery.

Released electrolyte has been known to

be harmful to the skin and eyes, and to be

toxic.



The electrolyte is a dilute sulfuric acid that

is harmful to the skin and eyes. It is electri-

cally conductive and corrosive.

The following procedures are to be observed:

• Wear full eye protection and protective clothing.

• Where electrolyte contacts the skin, wash it off

immediately with water.

• Where electrolyte contacts the eyes, flush thor-

oughly and immediately with water and seek

medical attention.

• Spilled electrolyte is to be washed down with

an acid neutralizing agent. A common practice

is to use a solution of 1 pound (500 grams)

bicarbonate of soda to 1 gallon (4 liters) of

water. The bicarbonate of soda solution is to

be added until the evidence of reaction (foam-

ing) has ceased. The resulting liquid is to be

flushed with water and the area dried.



Lead-acid batteries present a risk of fire

because they generate hydrogen gas. The fol-

lowing procedures are to be followed:

• DO NOT SMOKE when near the battery.

• DO NOT cause flame or spark in battery area.

• Discharge static electricity from body before

touching the battery by first touching a ground-

ed metal surface.



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.

General Information

14





Be sure the utility power supply is turned off

and the 7.5A fuse is removed from the gener-

ator control panel, or sparking may occur at

the battery posts as the cables are attached

and cause an explosion.

Servicing of the battery is to be performed or supervised by per-

sonnel knowledgeable of batteries and the required precautions.

Keep unauthorized personnel away from batteries.

See the Specifications section for the correct size and rating when

replacing the battery. Have these procedures performed at the

intervals specified in the “Service Schedule.” A negative ground

system is used. Battery connections are shown on the wiring dia-

grams. Make sure the battery is correctly connected and terminals

are tight. Observe battery polarity when connecting the battery to

the generator set.

1.16 BATTERY CHARGER

NOTE:

The battery charger is integrated into the control module in all

models.

It operates as a "Smart Charger" which ensures output is continu-

ally optimized to promote maximum battery life and charging levels

are at safe conditions.

NOTE:

There is a warning on the LCD display when the battery needs

service.

2.1 ACTIVATE THE GENERATOR

When battery power is applied to the generator during the installa-

tion process, the controller will light up. 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.

After obtaining your activation code, please complete the following

steps at the generator’s control panel as outlined by the Activation

Chart.

2.2 BEFORE INITIAL START-UP

NOTE:

These units have been run and tested at the factory prior to

being shipped and do not require any type of break-in.

NOTE:

level and add the appropriate amount if necessary.

Before starting, complete the following:

1. Set the generator’s main circuit breaker to its OFF (or OPEN)

position.

2. Set the generator's AUTO/OFF/MANUAL switch to the OFF

position.

3. Turn OFF all breakers on the load center of the transfer box (T1

and T2).

4. Turn OFF all loads connected to the transfer switch terminals

T1 and T2.

5. Check the engine crankcase oil level and, if necessary, fill to

the dipstick FULL mark with the recommended oil. Do not fill

above the FULL mark.

6. Check the fuel supply. Gaseous fuel lines must have been

properly purged and leak tested in accordance with applicable

fuel-gas codes. All fuel shutoff valves in the fuel supply lines

must be open.

During initial start up only, the generator may exceed the normal

number of start attempts and experience an “over crank” fault (See

the "Overcrank" section). This is due to accumulated air in the fuel

system during installation. Reset the control board and restart up

to two more times, if necessary. If unit fails to start, contact the

local dealer for assistance.



Never operate the engine with the oil level

below the “Add” mark on the dipstick. Doing

this could damage the engine.

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.

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 sim-

ply: Current Date/Time and Exercise Day/Time. The maintenance

intervals will be initialized when the exercise time is entered (Figure

3.1).

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 cur-

rent 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.

NOTE:

The exerciser will only work in the AUTO mode and will not work

unless this procedure is performed. The current date/time will

need to be reset every time the 12 volt battery is disconnected

and then reconnected, and/or when the fuse is removed.

Low Speed Exercise

16, 17 & 20kW units will run at 2,400 rpm.

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".)

3.2 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 (Figure 3.1).

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.

3.3 SEQUENCE OF AUTOMATIC

OPERATION

3.3.1 UTILITY FAILURE

Initial Conditions: Generator in Auto, ready to run, load being sup-

plied by utility source. When utility fails (below 60% of nominal),

a 10 second (optionally programmable) line interrupt delay time is

started. If the utility is still gone when the timer expires, the engine

will crank and start. Once started, a five (5) second engine warm-

up timer will be initiated. When the warm-up timer expires, the

control will transfer the load to the generator. If the utility power is

restored (above 80% of nominal) at any time from the initiation of

the engine start until the generator is ready to accept load (5 sec-

ond warm-up time has not elapsed), the controller will complete

the start cycle and run the generator through its normal cool down

cycle; however, the load will remain on the utility source.

3.3.2 CRANKING

The system will control the cyclic cranking as follows: 16 second

crank, seven (7) second rest, 16 second crank, seven (7) second

rest followed by three (3) additional cycles of seven (7) second

cranks followed by seven (7) second rests.

Choke Operation

1. The 990/999cc engines have an electric choke in the air

box that is automatically controlled by the electronic control

board.

2. The 530cc engines have an electric choke on the divider panel

air inlet hose that is automatically controlled by the electronic

control board.

3. The 410cc engines have a choke behind the air box that is

automatically controlled by the electronic control board.

Failure to Start

This is defined as any of the following occurrences during crank-

ing:

1. Not reaching starter dropout within the specified crank cycle.

Starter dropout is defined as four (4) cycles at 1,000 RPM.

2. Reaching starter dropout, but then not reaching 2200 RPM

within 15 seconds. In this case the control board will go into

a rest cycle for seven (7) seconds, then continue the rest of

the crank cycle.

During a rest cycle the start and fuel outputs are de-energized and

the magneto output is shorted to ground.

Cranking Conditions

The following notes apply during cranking cycle.

1. Starter motor will not engage within five (5) seconds of the

engine shutting down.

2. The fuel output will not be energized with the starter.

3. The starter and magneto outputs will be energized together.

4. Once the starter is energized the control board will begin look-

ing for engine rotation. If it does not see an RPM signal within

three (3) seconds it will shut down and latch out on RPM

sensor loss.

5. Once the control board sees an RPM signal it will energize the

fuel solenoid, drive the throttle open and continue the crank

sequence.

6. Starter motor will disengage when speed reaches starter

dropout.

7. If the generator does not reach 2200 RPM within 15 seconds,

re-crank cycle will occur.

8. If engine stops turning between starter dropout and 2200

RPM, the board will go into a rest cycle for seven (7) seconds

then re-crank (if additional crank cycles exist).

9. Once started, the generator will wait for a hold-off period

before starting to monitor oil pressure and oil temperature

(refer to the Alarm Messages section for hold-off times).

10. During Manual start cranking, if the Mode switch is moved

from the Manual position, the cranking stops immediately.

11. During Auto mode cranking, if the Utility returns, the cranking

cycle does NOT abort but continues until complete. Once the

engine starts, it will run for one (1) minute, then shut down.
