Safety Rules

SAFETY RULES

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.

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, efficiently 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 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.

Despite the safe design of this generator,

operating this equipment imprudently, neglecting 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 running generators.

Installation must always comply with appli-

cable codes, standards, laws and regulations.

A running generator gives off carbon mon-

oxide, an odorless, colorless poison gas. Breathing in carbon monoxide can cause headaches, fatigue, diziness, nausea, vomitting, confusion, fainting, siezures or death.

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.

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.

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 does the standby generator when it is in

operation. Avoid contact with bare wires, terminals, connec-

tions, etc., while the unit is running. Ensure all appropriate

covers, guards and barriers are in place, secured and/or locked

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.

Safety Rules

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 (generator) 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 15A 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 installation, 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 questions 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 applicable code. After installation, inspect the fuel system periodically for leaks. No leakage is permitted.

General Information

Only qualified electricians or contractors

should attempt such installations, which must comply strictly with applicable codes, standards and regulations.

There are LED readouts on the control panel to notify personnel that one of these faults has occurred. There is also a System Set LED that is lit when all of the conditions described in section "System Set LED" are true. (See the "Protection Systems" section for details.)

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 protective enclosure that is intended for outdoor installation only.

This UL listed standby generator set is packaged with an auto-•

matic transfer switch with built in load center. The combination 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 AC amperes at 250 •

volts maximum. This transfer switch is for indoor use only (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 transfer switch. The transfer switch must effectively isolate the electrical system from the utility distribution system when the generator is operating (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 contents of a package that is not in evidence at the time of delivery, but is discovered later.

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 following systems that protect it against potentially damaging conditions:

1. Low Oil Pressure Sensor 4. Overspeed

2. High Temperature Sensor 5. RPM Sensor

3. Overcrank 6. Low Battery

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 recognizing 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 circuit 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 dwelling 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.

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

1.6 SYSTEM SET LED

The “System Set” LED is lit 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 set light will flash rapidly. 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.

1.7 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 5 inches to 7 inches

water column (0.18 to 0.25 psi); and for liquid propane, 10 inches to 12 inches of water column (0.36 to 0.43 psi).

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 below four (4) inches water column for natural gas or 10 inches water column for liquid propane.

Prior to installation of the generator, the installer should consult local fuel suppliers or the fire marshall to check codes and regulations for proper installation. Local codes will mandate correct routing 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 fitting.

All installed gaseous fuel piping must be purged and leak tested prior to initial start-up in accordance with local codes, standards and regulations.

*Natural gas is in cubic feet per hour. **LP is in gallons per hour/cubic feet per hour. *** Values given are approximate.

1.8.1 BTU FLOW REQUIREMENTS - NATURAL GAS

BTU flow required for each unit based on 1000 BTU per cubic foot.

6kW — 119,000 BTU/Hour• 9kW — 156,000 BTU/Hour• 13kW — 220,000 BTU/Hour• 15kW — 245,000 BTU/Hour•

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 easily accessible. Local codes determine the proper location.

General Information

1.9 RECONFIGURING THE

FUEL SYSTEM

1.9.1 7 KW, 410CC ENGINE

To reconfigure the fuel system from NG to LP, follow these steps (Figure 1.4):

NOTE:

The primary regulator for the propane supply is NOT INCLUDED with the generator. A fuel pressure of 10 to 12 inches of water column (0.36 to 0.43 psi) to the fuel inlet of the generator MUST BE SUPPLIED.

1. Turn off the main gas supply (if connected).

2. Open the roof and remove the door.

3. Remove the battery (if installed).

4. Disconnect wire #0 and wire #14 from the gas solenoid on

top of the demand regulator.

5. Remove the carburetor fuel hose from the outlet port of the

The transfer switch shipped with this generator is enclosed in a NEMA 1 enclosure. This type of enclosure is intended for indoor use only. Follow these rules:

Install the transfer switch indoors on a firm, sturdy supporting •

structure.

To prevent switch distortion, level the switch if necessary. This •

can be done by placing washers between the switch enclosure and mounting surface.

Never install the switch where water or any corrosive substance •

might drip onto the enclosure.

Protect the switch at all times against excessive moisture, dust, •

dirt, lint, construction grit and corrosive vapors.

1.12 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 following 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 15A fuse from the generator control panel.

Battery cables were factory connected at the generator (Figure

1.10). Connect cables to battery posts as follows:

4. Connect the red battery cable (from star ter 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 (—).

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 1.10 – Battery Cable Connections

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.

1.11 BATTERY REQUIREMENTS

See the Specifications section for correct battery size and rating.

NOTE: In areas where temperatures regularly fall below 10° F (-12° C) it is recommended that a pad type battery heater be installed to aid in cold climate starting (see Specifications).

NOTE:

The generator is equipped with a battery trickle charger that is active when the unit is set up for automatic operation. With the battery installed and utility power source voltage available to the transfer switch, the battery receives a trickle charge while the engine is not running, to prevent self-discharge. The trickle charger is designed to help extend the life of the battery by maintaining the battery when the unit is not running. The trickle charge feature cannot be used to recharge a discharged battery.

Post Installation Start-up and Adjustments

1.13 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 working on batteries:

• Remove the 15A fuse from the generator control 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; and

• Disconnect charging source prior to connecting or disconnecting battery terminals.

Do not open or mutilate the battery. Released electrolyte has been known to

n

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 electrically 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 thoroughly and immediately with water and seek medical attention; and

• 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 (foaming) 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 following procedures are to be followed:

• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark in battery area;

and

• Discharge static electricity from body before touching the battery by first touching a grounded 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.

Be sure the utility power supply is turned off and the 15A 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 personnel 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. When using a maintenance-free battery, it is not necessary to check the specific gravity or electrolyte level. 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 diagrams. Make sure the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the generator set.

2.1 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.

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, after installation, it is normal for the generator to exceed the normal number of start attempts and experience an “over crank” fault. This is due to accumulated air in the fuel system during shipment.

NOTE:

This procedure applies to 13kW and 16kW units only and should be performed by trained personnel.

Never operate the engine with the oil level

below the “Add” mark on the dipstick. Doing this could damage the engine.

Post Installation Start-up and Adjustments

2.2 CHECK TRANSFER SWITCH OPERATION

Refer to the "Manual Transfer Operation" section, of the owner’s manual for procedures.

Do not attempt manual transfer switch opera-



tion until all power voltage supplies to the transfer switch have been positively turned off. Failure to turn off all power voltage supplies will result in extremely hazardous and possibly fatal electrical shock.

2.3 ELECTRICAL CHECKS

Complete electrical checks as follows:

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.



“hot.” Contact with “hot” parts will result in extremely hazardous and possibly fatal electrical shock. Proceed with caution.

5. Use an accurate AC voltmeter to check utility power source

voltage across transfer switch terminals N1 and N2. Nominal line-to-line voltage should be 240 volts AC.

6. Check utility power source voltage across terminals N1 and

the transfer switch neutral lug; then across terminal N2 and neutral. Nominal line-to-neutral voltage should be 120 volts AC.

7. When certain that utility supply voltage is compatible with

transfer switch and load circuit ratings, turn OFF the utility power supply to the transfer switch.

8. On the generator panel, set the AUTO/OFF/ MANUAL switch to

MANUAL. The engine should crank and start.

9. Let the engine warm up for about five minutes to allow inter-

nal temperatures to stabilize. Then, set the generator’s main circuit breaker to its ON (or CLOSED) position.

Proceed with caution! Generator power volt-



age is now supplied to the transfer switch. Contact with live transfer switch parts will result in dangerous and possibly fatal electrical shock.

10. Connect an accurate AC voltmeter and a frequency meter across transfer switch terminal lugs E1 and E2. 7kW voltage should be 242-252 volts at a frequency of 61-63 Hertz. 10, 13, and 16kW voltage should be 247-249 volts at a frequency of 57.5-59.5 Hertz.

11. Connect the AC voltmeter test leads across terminal lugs E1 and neutral; then across E2 and neutral. In both cases, voltage reading should be 121-126 volts AC (7kW), and 125-126 volts AC (10, 13 and 16kW).

12. Set the generator’s main circuit breaker to its OFF (or OPEN) position. Let the engine run at no-load for a few minutes to stabilize internal engine generator temperatures.

13. Set the generator's AUTO/OFF/MANUAL switch to OFF. The engine should shut down.

NOTE:

It is important not to proceed until certain that generator AC voltage and frequency are correct and within the stated limits. Generally, if both AC frequency and voltage are high or low, the engine governor requires adjustment* (*GH410 only). If frequency is correct, but voltage is high or low, the generator’s voltage regulator requires adjustment.

2.4 GENERATOR TESTS UNDER

After starting, the transfer switch should connect load circuits to the standby side after a 15 second delay. Let the system go through its entire automatic sequence of operation.

With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur:

After about 15 seconds, the switch should transfer loads back •

to the utility power source.

About one minute after retransfer, the engine should shut •

down.

2.6 ADJUSTING THE FUEL REGULATOR - 7KW (NATURAL GAS ONLY)

NOTE:

All V-twin engine units DO NOT require a fuel regulator adjustment due to the fuel system design.

Although the generator has been factory set to provide maximum power, it may be necessary in some areas to adjust this setting. If experiencing engine problems at high or full load conditions, follow these steps. It will require a frequency meter to perform this procedure.

1. Turn off utility power to the main distribution panel in the

house. This can be done by switching the service main breaker to the off or open position.

2. Allow the generator to start. Before loading the generator,

confirm that the No Load Frequency, with the roof open and door off, is set to 63-63.5 Hz. Transfer load to emergency circuits.

3. Turn on appliances, lights, pumps, etc., that are on the emer-

gency circuits in an attempt to fully load the generator. Be cautious not to overload the generator. Use the following chart as a guide:

4. When 3/4 load has been achieved. Connect a frequency meter

to the output lugs of the generator’s main line circuit breaker.

5. The fuel regulator is fitted with one adjustment screw. While

watching the frequency meter, slowly turn the adjustment screw clockwise or counterclockwise until the highest frequency is read on the meter. Only limited adjustment is available because of the set pin. Under no circumstances should any of the pins be removed (Figure 2.3).

Figure 2.3 — 7kW Fuel Regulator

6. When the highest frequency is reached maximum power has

been set. From this point turn the adjustment screw 1/4 turn counterclockwise. The regulator is now set.

7. Turn utility power to the main distribution panel back on. This

can be done by switching the service main breaker to the on or closed position. Allow the generator to shut down.

Set the switch to MANUAL to crank and start the engine. Transfer to standby power will not occur unless there is a utility failure.

With the switch set to AUTO, the engine may crank and start at any time without warning.

Such automatic starting normally 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 fuses before working on or around the generator or transfer switch. Then, place a “DO NOT OPERATE” tag on the generator panel and on the transfer switch.

3.1.4 CHOKE OPERATION

1. 990 engines have an electric choke in the air box that is automatically controlled by the electronic control board.

2. 530 engines have an electric choke on the divider panel air inlet hose that is automatically controlled by the electronic control board.

3. 410 engines do not have a choke.

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 3.2).

2. Be sure that normal UTILITY power source voltage is available 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 automatically 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.

Operation

3.3 SEQUENCE OF AUTOMATIC OPERATION

The generator’s control panel houses a control logic circuit board. This board constantly monitors utility power source voltage. Should that voltage drop below a preset level, circuit board action will signal the engine to crank and start. After the engine starts, the circuit board signals the transfer switch to activate and connect load circuits to the standby power supply (load terminal lugs T1/T2 connect to terminal lugs E1/E2). Refer to the Electrical Data section.

The generator must run at 50 Hz or greater for the transfer output to be activated. Once activated, it will remain active even if the frequency dips below 50 Hz.

Upon restoration of utility source voltage above a preset level, generator circuit board action signals the transfer switch to transfer loads back to that power supply. After retransfer, the engine is signalled to shut down.

The actual sequence of operation is controlled by sensors and timers on a control logic circuit board, as follows:

A. Utility Voltage Dropout Sensor

• This sensor monitors utility source voltage.

• If utility source voltage drops below about 65 percent of the nominal supply voltage, the sensor energizes a 10 second timer.

• Once the timer has expired, the engine will crank and star t if utility is still low.

B. Engine Warm-up Time Delay

• This mechanism lets the engine warm up for about five (5) seconds before the load is transferred to the standby source.

C. Standby Voltage Sensor

• This sensor monitors generator AC output voltage. When the voltage has reached 50 percent of the nominal rated voltage, transfer to standby can occur.

D. Utility Voltage Pickup Sensor

• This sensor monitors utility power supply voltage. When that voltage is restored above 75 percent of the nominal source voltage, a retransfer time delay starts timing.

E. Retransfer Time Delay

• This timer runs for about 15 seconds.

• At end of a 15-second delay, circuit board action de-energizes transfer relay in the transfer switch if utility is still present.

• Retransfer to utility power source then occurs.

F. Engine Cool-down Timer

• When the load is transferred back to utility power source, the engine cool-down timer starts timing.

• The timer will run for about one minute, and the generator will then shut down.

3.4 MANUAL TRANSFER OPERATION

3.4.1 TRANSFER TO GENERATOR

POWER SOURCE

To start the generator and activate the transfer switch manually, proceed as follows:

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

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

position.

3. Turn OFF the utility power supply to the transfer switch

using the means provided (such as a utility main line circuit breaker).

Do not attempt to activate the transfer switch



manually until all power voltage supplies to the switch have been positively turned off. Failure to turn off all power voltage supplies may result in extremely hazardous and possibly fatal electrical shock.

4. Use the manual transfer handle inside the transfer switch to

move the main contacts to their STANDBY position, i.e., loads connected to the standby power source (Figure 3.2).

5. To crank and start the engine, set the AUTO/OFF/MANUAL

switch to MANUAL.

6. Let the engine stabilize and warm up for a few minutes.

7. Set the generator’s main circuit breaker to its ON (or CLOSED)

position. The standby power source now powers the loads.

Figure 3.2 – Manual Transfer Switch Operation

Operation

3.4.2 TRANSFER BACK TO UTILITY POWER SOURCE

When utility power has been restored, transfer back to that source and shut down the generator. This can be accomplished as follows:

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

2. Let the engine run for a minute or two at no-load to stabilize the internal temperatures.

3. Set the generator’s AUTO/OFF/MANUAL switch to its OFF (or OPEN) position. The engine should shut down.

4. Check that utility power supply to the transfer switch is turned OFF.

Do not attempt to activate the transfer switch



5. Use the manual transfer handle inside the transfer switch to move the main contacts back to their UTILITY position, i.e., loads connected to the utility power source (Figure 3.2).

6. Turn ON the utility power supply to the transfer switch using the means provided.

7. Set the system to automatic operation as outlined in Automatic Transfer Operation section.

3.5 SETTING THE EXERCISE TIMER

This generator is equipped with an exercise timer. Once it is set, the generator will start and exercise once every seven days, on the day of the week and at the time of day the following sequence is completed. 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.

A switch on the control panel (see Figure 3.1) permits selection of the day and time for the system to exercise. At the chosen time, perform the following sequence to select the desired day and time of day the system will exercise. Remember seasonal time changes affect the exercise time settings.

1. Verify that the AUTO/OFF/MANUAL switch is set to AUTO.

2. Press and hold the "Set Exercise Time" switch for several seconds, then release. All the red LED's will flash for approximately 10 seconds and then stop.

3. Once the red LED's stop flashing, the generator will start and run for approximately 12 minutes and then shut down. The exerciser is now set to run at this time of day each week.

Example: If the "Set Exercise Time" switch is pressed on

Saturday afternoon at 2:00 p.m., the generator will star t and exercise for approximately 12 minutes every Saturday at 2:00 p.m..

NOTE:

The exerciser will only work in the AUTO mode and will not work unless this procedure is performed. The exerciser will need to be reset every time the 12-volt battery is disconnected and then reconnected, and when the 15A fuse is removed.

The 16kW unit has a low speed exercise option. Dip switch 1 on the control board is factory set to OFF. This allows the engine to run at a slower speed during weekly exercise periods for quieter operation. If this Dip switch is set to ON, the generator will exercise at it's normal speed.

This DIP switch position is only read at board power up. If the DIP switch position is changed, power to the board must be cycled for the micro controller to recognize the new DIP switch position.

Low speed exercise will be handled as follows:

1. The standard star t sequence will be initiated.

2. The unit will run at 2,400 RPM.

3. If utility is lost during exercise, the controller will do the following:

• Wait 10 seconds for utility to return.

• If utility returns within 10 seconds, continue to exercise at 2,400 RPM.

• If utility is still lost after 10 seconds, run the engine up to 3600 RPM and transfer the load. At this time the controller will exit the exercise routine and assume full automatic operation.

3.6 PROTECTION SYSTEMS

3.6.1 LOW OIL PRESSURE SWITCH

This switch (Figure 3.3) has normally closed contacts that are held open by engine oil pressure during cranking and operating. Should oil pressure drop below the 8 psi range, switch contacts close, and the engine shuts down. The unit should not be restarted until oil is added. The AUTO/OFF/MANUAL switch must then be turned to OFF and then back to AUTO.

3.6.2 HIGH TEMPERATURE SWITCH

This switch’s contacts (Figure 3.3) close if the temperature should exceed approximately 144º C (293º F), initiating an engine shutdown. The generator will automatically restart and the LED on the generator control panel will reset once the temperature has returned to a safe operating level.

3.6.3 OVERCRANK

This feature prevents the generator from damaging itself when it continually attempts to start and another problem, such as no fuel supply, prevents it from starting. The unit will crank and rest for a preset time limit. Then, it will stop cranking, and the LED on the generator control panel will light indicating an overcrank failure. The AUTO/OFF/MANUAL switch will need to be set to OFF and then back to AUTO to reset the generator control board.

NOTE:

If the fault is not repaired, the overcrank feature will continue to activate.

If the unit fails to start, the overcrank alarm LED will be illuminated.

3.6.4 OVERSPEED

This feature protects the generator from damage by shutting it down if it happens to run faster than the preset limit. This protection also prevents the generator from supplying an output that could potentially damage appliances connected to the generator circuit. Contact the nearest Authorized Dealer if this failure occurs.

3.6.5 RPM SENSOR FAILURE

During cranking, if the board does not see a valid RPM signal within three (3) seconds, it will shut down and latch out on RPM sensor loss.

During running, if the RPM signal is lost for one full second the board will shut down the engine, wait 15 seconds, then re-crank the engine.

If an RPM signal is not detected within the first three (3) sec-•

onds 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 nor-•

mally. If the RPM signal is subsequently lost again, the control board will try one more re-crank attempt before latching out and flashing the overspeed LED.

3.6.6 LOW BATTERY

The microprocessor will continually monitor the battery voltage and turn on the Low Battery LED if the battery voltage falls below

11.0 volts for one (1) minute. No other action is taken on a low battery condition. Low battery voltage is a non-latching alarm which will automatically clear if the battery voltage rises above 11.0 volts. Battery voltage is NOT monitored during the crank cycle.

4.1 FUSES

The 15-amp fuse on the generator panel protects the DC control circuit against overload (Figure 4.1). This fuse is wired in series with the battery output lead to the panel. If this fuse element has melted open, the engine will not be able to crank or start. Replace this fuse using only an identical 15-amp replacement fuse. To replace the fuse, push the fuse holder cap down and rotate it counterclockwise. Whenever the fuse is removed or replaced, the exercise timer needs to be reset.

because they generate hydrogen gas. The following procedures are to be followed:

• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark in battery area;

and

• Discharge static electricity from body before touching the battery by first touching a grounded 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.

Be sure the utility power supply is turned off



and the 15A fuse is removed from the generator control panel, or sparking may occur at



the battery posts as the cables are attached and cause an explosion.

Make sure the piston is at Top Dead Center (TDC) of its com-•

pression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine in a clockwise direction. While watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is at its highest point of travel.

To adjust valve clearance (if necessary):

Make sure the engine is at 60° to 80° F.• Make sure that the spark plug wire is removed from the spark •

plug and out of the way.

Remove the four screws attaching the valve cover with a #2 or •

#3 Phillips screwdriver.

Loosen the rocker jam nut. Use an 10mm allen wrench to turn •

the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm).

VALVE CLEARANCE

After the first six (6) months of operation, check the valve clearance in the engine, adjust if necessary.

Important: If feeling uncomfortable about doing this procedure or

the proper tools are not available, please contact the Authorized Dealer for service assistance. This is a very important step to insure longest life for the engine.

To check valve clearance:

The engine should be cool before checking. If valve clearance is •

0.002" - 0.004" (0.05 - 0.1mm), adjustment is not needed. Remove spark plug wires and position wires away from plugs.• Remove spark plugs.•

NOTE:

Hold the rocker arm jam nut in place as the pivot ball stud is turned.

When valve clearance is correct, hold the pivot ball stud in place with the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change.

Install new valve cover gasket.• Re-attach the valve cover.•

NOTE:

Start all four screws before tightening or it will not be possible to get all the screws in place. Make sure the valve cover gasket is in place.

Install spark plugs.• Re-attach the spark plug wire to the spark plug.• On the GT-530 and GT-990, repeat the process for the other •

cylinder.

Maintenance

4.8 COOLING SYSTEM

Air inlet 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/generator quickly overheats, which causes it to quickly shut down. (See Figure 4.11 for vent locations.)

Make sure the doors and roof are in place during operation as running the generator with them removed can effect cooling air movement.

Figure 4.11 – Cooling Vent Locations

The exhaust from this product gets 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.

4.10 CORROSION PROTECTION

Periodically wash and wax the enclosure using automotive type products. Frequent washing is recommended in salt water/coastal areas. Spray engine linkages with a light oil such as WD-40.

4.11 OUT OF SERVICE PROCEDURE

4.11.1 REMOVAL FROM SERVICE

If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, prepare the generator for storage as follows:

1. Star t the engine and let it warm up.

2. Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down.

3. Once the unit has shut down, it will signal a low oil fault.

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

5. Set the AUTO/OFF/MANUAL switch to OFF and turn off the utility power to the transfer switch. Remove the 15A fuse from the generator control panel. Disconnect the battery cables as outlined in “General Hazards”.

2. Unit should be Registered and Proof of Purchase and Maintenance must be available.

3. Warranty is transferable between ownership of original installation site.

4. Warranty only applies to permanently wired and mounted units.

5. Any and all warranty repairs and/or concerns, must be performed and/or addressed by an Authorized/Cer tified Generac Service Dealer, or branch thereof. Repairs or diagnostics per-

formed by individuals other than Authorized/Certified Generac Service Dealers not authorized in writing by Generac will not be covered.

6. A Generac Transfer Switch is highly recommended to be used in conjunction with the generator set. If a Non-Generac Transfer Switch is substituted for use and directly causes dam-

age to the generator set, no warranty coverage shall apply.

7. Steel enclosures are warranted against rusting for the first year of ownership only. Damage caused after receipt of generator is the responsibility of the owner and is not covered by

this warranty. Nicks, scrapes, dents or scratches to the painted enclosure should be repaired promptly by the owner.

8. All warranty expense allowances are subject to the conditions defined in Generac's General Service Policy Manual.

1. Any unit built/manufacturer prior to April 2010.

2. Generac generators that utilize non-Generac replacement parts.

3. Costs of normal maintenance (i.e. tune-ups, associated part(s), adjustments, loose/leaking clamps, installation and start-up).

4. Units sold, rated or used for "Prime Power", "Trailer Mounted" or "Rental Unit" applications as Generac has defined Prime Power, Trailer Mounted or Rental Unit. Contact a Generac

Distributor for Prime Power, Trailer Mounted or Rental Unit definition.

5. Damage to generator system (including transfer switch) caused by improper installation or costs necessary to correct installation.

6. Units used for Prime Power in place of existing utility power (where utility power is present) or in place of utility power where utility power service does not normally exist.

7. Fuel connections other than conventional utility company supplied natural gas systems or conventional LP vapor withdrawal systems.

8. Any failure caused by contaminated fuels, oils, coolants/antifreeze or lack of proper fuels, oils or coolants/antifreeze.

9. Steel enclosures that are rusting due to the improper installation, location in a harsh or saltwater environment or scratched where integrity of paint applied is compromised.

10. Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with all mechanical devices, the Generac engines need periodic

part(s) service and fluid replacement to perform as designed. This warranty will not cover repair when normal use has exhausted the life of a part(s) or engine.

11. Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire, freezing, lightning, earthquake, windstorm, hail, volcanic

eruption, water or flood, tornado or hurricane.

12. Damage related to rodent and/or insect infestation.

13. Products that are modified or altered in a manner not authorized by Generac in writing.

14. Covered warranty labor rates are based on normal working hours. Overtime, holiday, or emergency labor costs for repairs outside of normal business hours will be the responsibility

of the customer.

15. Any incidental, consequential or indirect damages caused by defects in materials or workmanship, or any delay in repair or replacement of the defective part(s).

16. Failure due to misapplication.

17. Telephone, cellular phone, facsimile, internet access or other communication expenses.

18. Living or travel expenses of person(s) performing service, except as specifically included within the terms of a specific unit warranty period.

19. Expenses related to "customer instruction" or troubleshooting where no manufacturing defect is found.

20. Rental equipment used while warranty repairs are being performed and/or overnight freight costs for replacement par t(s).

21. Costs incurred for equipment used for removal and/or reinstallation of generator, (i.e.: cranes, hoists, lifts, etc.)

22. Planes, ferries, railroad, buses, helicopters, snowmobiles, snow-cats, off-road vehicles or any other mode of transport deemed abnormal.

23. Starting batteries, fuses, light bulbs and engine fluids.

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES NO OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Any implied warranties which are allowed by law, shall be limited in duration to the terms of the express warranty provided herein. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT SHALL GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A DIRECT RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you. This warranty gives you specific legal rights. You also have other rights from state to state.
