PAGE 8 — DCA45SSK/KU3 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (12/15/11)

SAFETY INFORMATION

ENGINE SAFETY

DANGER

The engine fuel exhaust gases contain poisonous carbon

monoxide. This gas is colorless and odorless, and can

cause death if inhaled.

The engine of this equipment

requires an adequate free

fl ow of cooling air. NEVER

operate this equipment in

any enclosed or narrow area

where free fl ow of the air is

restricted. If the air fl ow is

restricted it will cause injury to people and property and

serious damage to the equipment or engine.

WARNING

DO NOT place hands or fingers inside engine

compartment when engine is running.

NEVER operate the engine with heat shields or

guards removed.

Keep fi ngers, hands hair and clothing away

from all moving parts to prevent injury.

DO NOT remove the radiator cap while the

engine is hot. High pressure boiling water

will gush out of the radiator and severely

scald any persons in the general area of

the generator.

DO NOT remove the coolant drain plug while the engine

is hot. Hot coolant will gush out of the coolant tank and

severely scald any persons in the general area of the

generator.

DO NOT remove the engine oil drain plug while the

engine is hot. Hot oil will gush out of the oil tank and

severely scald any persons in the general area of the

generator.

CAUTION

NEVER touch the hot exhaust manifold,

muffl er or cylinder. Allow these parts to cool

before servicing equipment.

NOTICE

NEVER

run engine without an air fi lter or with a dirty air

fi lter. Severe engine damage may occur. Service air fi lter

frequently to prevent engine malfunction.

NEVER tamper with the factory settings

of the engine or engine governor. Damage

to the engine or equipment can result

if operating in speed ranges above the

maximum allowable.



Wet stacking is a common problem with diesel engines

which are operated for extended periods with light or

no load applied. When a diesel engine operates without

suffi cient load (less than 40% of the rated output), it will

not operate at its optimum temperature. This will allow

unburned fuel to accumulate in the exhaust system,

which can foul the fuel injectors, engine valves and

exhaust system, including turbochargers, and reduce

the operating performance.

In order for a diesel engine to operate at peak effi ciency,

it must be able to provide fuel and air in the proper ratio

and at a high enough engine temperature for the engine

to completely burn all of the fuel.

Wet stacking does not usually cause any permanent

damage and can be alleviated if additional load is

applied to relieve the condition. It can reduce the system

performance and increase maintenance. Applying an

increasing load over a period of time until the excess

fuel is burned off and the system capacity is reached

usually can repair the condition. This can take several

hours to burn off the accumulated unburned fuel.

State Health Safety Codes and Public Resources

Codes specify that in certain locations, spark arresters

must be used on internal combustion engines that use

hydrocarbon fuels. A spark arrester is a device designed

to prevent accidental discharge of sparks or fl ames

from the engine exhaust. Spark arresters are qualifi ed

and rated by the United States Forest Service for this

purpose. In order to comply with local laws regarding

spark arresters, consult the engine distributor or the

local Health and Safety Administrator.

INSTALLATION

Figure 2. Typical Generator Grounding Application

DCA45SSK/KU3 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (12/15/11) — PAGE 15

INSTALLATION

OUTDOOR INSTALLATION

Install the generator in a area that is free of debris,

bystanders, and overhead obstructions. Make sure the

generator is on secure level ground so that it cannot slide

or shift around. Also install the generator in a manner so

that the exhaust will not be discharged in the direction of

nearby homes.

The installation site must be relatively free from moisture

and dust. All electrical equipment should be protected from

excessive moisture. Failure to do will result in deterioration

of the insulation and will result in short circuits and

grounding.

Foreign materials such as dust, sand, lint and abrasive

materials have a tendency to cause excessive wear to

engine and alternator parts.

INDOOR INSTALLATION

Exhaust gases from diesel engines are extremely

poisonous. Whenever an engine is installed indoors the

exhaust fumes must be vented to the outside. The engine

should be installed at least two feet from any outside wall.

Using an exhaust pipe which is too long or too small can

cause excessive back pressure which will cause the engine

to heat excessively and possibly burn the valves.

MOUNTING

The generator must be mounted on a solid foundation (such

as concrete) and set firmly on the foundation to isolate

vibration of the generator when it is running. The generator

must set at least 6 inches above the floor or grade level (in

accordance to NFPA 110, Chapter 5-4.1). DO NOT remove

the metal skids on the bottom of the generator. They are

to resist damage to the bottom of the generator and to

maintain alignment.

CAUTION

Pay close attention to ventilation when operating the

generator inside tunnels and caves. The engine exhaust

contains noxious elements. Engine exhaust must be

routed to a ventilated area.

GENERATOR GROUNDING

To guard against electrical shock and possible damage to

the equipment, it is important to provide a good EARTH

ground.

Article 250 (Grounding) of the National Electrical Code

(NEC) provides guide lines for proper grounding and

specifies that the cable ground shall be connected to the

grounding system of the building as close to the point of

cable entry as practical.

NEC articles 250-64(b) and 250-66 set the following

grounding requirements:

1. Use one of the following wire types to connect the

generator to earth ground.

a. Copper - 8 AWG (5.3 mm2)

b. Aluminum - 6 AWG (8.4 mm2)

2. When grounding the generator ( Figure 2) connect the

ground cable between the lock washer and the nut on

the generator and tighten the nut fully. Connect the

other end of the ground cable to earth ground.

3. NEC article 250-52 (5) specifies that the earth ground rod

should be buried a minimum of 8 ft. into the ground.

NOTICE

When connecting the generator to any buildings

electrical system ALWAYS consult with a licensed

electrician.

NOTICE

This generator has a permanent bonding conductor

between the generator stator windings and the frame.

OPEN DELTA EXCITATION SYSTEM

This generator is equipped with the state of the art “Open-

Delta” excitation system. The open delta system consist

of an electrically independent winding wound among

stationary windings of the AC output section.

There are four connections of the open delta A, B, C and

D. During steady state loads, the power from the voltage

regulator is supplied from the parallel connections of A to

B, A to D, and C to D. These three phases of the voltage

input to the voltage regulator are then rectified and are the

excitation current for the exciter section.

When a heavy load, such as a motor starting or a short

circuit occurs, the automatic voltage regulator (AVR)

switches the configuration of the open delta to the series

connection of B to C. This has the effect of adding the

voltages of each phase to provide higher excitation to the

exciter section and thus better voltage response during the

application of heavy loads.

The connections of the AVR to the AC output windings are

for sensing only. No power is required from these windings.

The open-delta design provides virtually unlimited excitation

current, offering maximum motor starting capabilities. The

excitation does not have a “fixed ceiling” and responds

according the demands of the required load.

ENGINE

This generator unit incorporates an Kubota V3800-DI-T-E3B

diesel engine. This engine is designed to meet every

performance requirement for the generator. Reference

Table 2 for engine specifications.

In keeping with MQ Power’s policy of constantly improving

its products, the specifications quoted herein are subject

to change without prior notice.

ELECTRIC GOVERNOR SYSTEM (OPTION)

The electric governor system controls the RPMs of the engine.

When the engine demand increases or decreases, the

governor system regulates the frequency variation to ±.25%.

EXTENSION CABLES

When electric power is to be provided to various tools or

loads at some distance from the generator, extension cords

are normally used. Cables should be sized to allow for

distance in length and amperage so that the voltage drop

between the generator and point of use (load) is held to

a minimum. Use the cable selection chart (Table 6) as a

guide for selecting proper extension cable size.

LOAD APPLICATION

SINGLE PHASE LOAD

Always be sure to check the nameplate on the generator

and equipment to insure the wattage, amperage, frequency,

and voltage requirements are satisfactorily supplied by the

generator for operating the equipment.

Generally, the wattage listed on the nameplate of the

equipment is its rated output. Equipment may require

130—150% more wattage than the rating on the nameplate,

as the wattage is influenced by the efficiency, power factor

and starting system of the equipment.

WATTS = VOLTAGE x AMPERAGE

The power factor of this generator is 0.8. SeeTable 5 below

when connecting loads.

CAUTION: Equipment damage can result from low voltage

NOTICE

If wattage is not given on the equipment’s name plate,

approximate wattage may be determined by multiplying

nameplate voltage by the nameplate amperage.

Table 5. Power Factor By Load

Single-phase induction motors 0.4-0.75

Electric heaters, incandescent lamps 1.0

Fluorescent lamps, mercury lamps 0.4-0.9

Electronic devices, communication

equipment 1.0

Common power tools 0.8

THREE PHASE LOAD

When calculating the power requirements for 3-phase

power use the following equation:

An inadequate size connecting cable which cannot carry the

required load can cause a voltage drop which can burn out

the appliance or tool and overheat the cable. See Table 6.

When connecting a resistance load such as an

incandescent lamp or electric heater, a capacity of up

to the generating set’s rated output (kW) can be used.

When connecting a fluorescent or mercury lamp, a

capacity of up to the generating set’s rated output (kW)

multiplied by 0.6 can be used.

When connecting an electric drill or other power tools,

pay close attention to the required starting current

capacity.

When connecting ordinary power tools, a capacity of up to

the generating set’s rated output (kW) multiplied by 0.8 can

be used.

NOTICE

Motors and motor-driven equipment draw much greater

current for starting than during operation.

NOTICE

If 3Ø load (kVA) is not given on the equipment

nameplate, approximate 3Ø load may be determined

by multiplying voltage by amperage by 1.732.

DANGER

Before connecting this generator to any building’s

electrical system, a licensed electrician must install

an isolation (transfer) switch. Serious damage to

the building’s electrical system may occur without this

transfer switch.

or malfunctions. Always keep the terminals firmly

tightened. Coating the terminals with an approved battery

terminal treatment compound. Replace battery with only

recommended type battery.

The battery is sufficiently charged if the specific gravity

of the battery fluid is 1.28 (at 68° F). If the specific gravity

should fall to 1.245 or lower, it indicates that the battery is

dead and needs to be recharged or replaced.

Before charging the battery with an external electric source,

be sure to disconnect the battery cables.

Battery Cable Installation

ALWAYS be sure the battery cables (Figure 35) are

properly connected to the battery terminals as shown below.

The red cable is connected to the positive terminal of the

battery, and the black cable is connected to the negative

terminal of the battery.

Figure 35. Battery Connections

CAUTION

ALWAYS disconnect the negative terminal FIRST and

reconnect negative terminal LAST.

When connecting battery do the following:

1. NEVER connect the battery cables to the battery

terminals when the MPEC Control Switch is in either

the MANUAL position. ALWAYS make sure that the

MPEC Control Switch is in the OFF/RESET position

when connecting the battery.

2. Place a small amount of battery terminal treatment

compound around both battery terminals. This will

ensure a good connection and will help prevent

corrosion around the battery terminals.

ALTERNATOR

The polarity of the alternator is negative grounding type.

When an inverted circuit connection takes place, the

circuit will be in short circuit instantaneously resulting the

alternator failure.

DO NOT put water directly on the alternator. Entry of water

into the alternator can cause corrosion and damage the

alternator.

WIRING

Inspect the entire generator for bad or worn electrical wiring

or connections. If any wiring or connections are exposed

(insulation missing) replace wiring immediately.

PIPING AND HOSE CONNECTION

Inspect all piping, oil hose, and fuel hose connections for

wear and tightness. Tighten all hose clamps and check

hoses for leaks.

If any hose (fuel or oil) lines are defective replace them

immediately.

NOTICE

If the battery cable is connected incorrectly, electrical

damage to the generator will occur. Pay close attention to

the polarity of the battery when connecting the battery.

CAUTION

Inadequate battery connections may cause poor

starting of the generator, and create other malfunctions.

MAINTENANCE

GENERAL INSPECTION

Prior to each use, the generator should be cleaned and

inspected for deficiencies. Check for loose, missing or

damaged nuts, bolts or other fasteners. Also check for

fuel, oil, and coolant leaks. Use Table 14 as a general

maintenance guideline Engine Side (Refer to the Engine

Instruction Manual)

AIR CLEANER

Every 250 hours: Remove air cleaner element (Figure 53)

and clean the heavy duty paper element with light spray of

compressed air. Replace the air cleaner as needed.

Air Cleaner with Dust Indicator

This indicator (Figure 53) is attached to the air cleaner.

When the air cleaner element is clogged, air intake

restriction becomes greater and the dust indicator signal

shows RED meaning the element needs changing or

service. After changing the air element, press the dust

indicator button to reset the indicator.

Figure 53. Air Cleaner/Indicator

NOTICE

The air filter should not be changed until the indicator

reads “RED”. Dispose of old air filter. It may not be

cleaned or reused.

PAGE 36 — DCA45SSK/KU3 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (12/15/11)

MAINTENANCE

If the engine is operating in very dusty or dry grass

conditions, a clogged air cleaner will result. This can lead to

a loss of power, excessive carbon buildup in the combustion

chamber and high fuel consumption. Change air cleaner

more frequently if these conditions exists.

FUEL ADDITION

Add diesel fuel (the grade may vary according to season

and locations).

Removing Water from the Fuel Tank

After prolonged use, water and other impurities accumulate

in the bottom of the tank. Occasionally inspect the fuel

tank for water contamination and drain the contents if

required.

During cold weather, the more empty volume inside the

tank, the easier it is for water to condense. This can be

reduced by keeping the tank full with diesel fuel.

Cleaning Inside the Fuel Tank

If necessary, drain the fuel inside the fuel tank completely.

Using a spray washer (Figure 54) wash out any deposits

or debris that have accumulated inside the fuel tank.

Figure 54. Fuel Tank Cleaning

FUEL TANK INSPECTION

In addition to cleaning the fuel tank, the following

components should be inspected for wear:

Rubber Suspension — look for signs of wear or

deformity due to contact with oil. Replace the rubber

suspension if necessary.

Fuel Hoses — inspect nylon and rubber hoses for signs

of wear, deterioration and hardening.

Fuel Tank Lining — inspect the fuel tank lining for signs

of excessive amounts of oil or other foreign matter.

Replacing Fuel Filter

Replace the fuel filter cartridge with new one every 500

hours or so.

Loosen the drain plug at the lower top of the fuel filter.

Drain the fuel in the fuel body together with the mixed

water. DO NOT spill the fuel during disassembly.

Vent any air

FUEL FILTER/WATER SEPARATOR

Inspect the fuel filter water separator daily. If the fuel filter/

water separator (Figure 55) has collected a significant

amount of water and sediment at the bottom of the cup, it

should be drained off. Refer to your engine manual for

specific details to perform this operation.

DCA45SSK/KU3 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (12/15/11) — PAGE 37

AIR REMOVAL

If air enters the fuel injection system of a diesel engine,

starting becomes impossible. After running out of fuel,

or after disassembling the fuel system, bleed the system

according to the following procedure. See the KUBOTA

Engine Manual for details.

To restart after running out of fuel, turn the switch to the

“ON” position for 15-30 seconds. Try again, if needed.

CHECK OIL LEVEL

Check the crankcase oil level prior to each use, or when the

fuel tank is filled. Insufficient oil may cause severe damage

to the engine. Make sure the generator is level. The oil

level must be between the two notches on the dipstick as

shown in Figure 28.

Replacing Oil Filter

Remove the old oil filter.

Apply a film of oil to the gasket on the new oil filter.

Install the new oil filter.

After the oil cartridge has been replaced, the engine oil

will drop slightly. Run the engine for a while and check for

leaks before adding more oil if needed. Clean excessive

oil from engine.

FLUSHING OUT RADIATOR AND REPLACING

COOLANT

Open both cocks located at the crankcase side and at

the lower part of the radiator and drain coolant. Open

the radiator cap while draining. Remove the overflow

tank and drain.

Check hoses for softening and kinks. Check clamps for

signs of leakage.

Tighten both cocks and replace the overflow tank.

Replace with coolant as recommended by the engine

manufacturer.

Close radiator cap tightly.

Flush the radiator by running clean tap water through

radiator until signs of rust and dirt are removed. DO

NOT clean radiator core with any objects, such as a

screwdriver.

RADIATOR CLEANING

The radiator (Figure 56) should be sprayed (cleaned) with

a high pressure washer when excessive amounts of dirt

and debris have accumulated on the cooling fins or tube.

When using a high pressure washer, stand at least 5 feet

(1.5 meters) away from the radiator to prevent damage to

the fins and tube.

Figure 56. Radiator Cleaning

GENERATOR STORAGE

For long term storage of the generator the following is

recommended:

Drain the fuel tank completely. Treat with a fuel stabilizer

if necessary.

Completely drain the oil from the crankcase and refill if

necessary with fresh oil.

Clean the entire generator, internal and external.

Cover the generating set and store in a clean, dry place.

Disconnect the battery.

Make sure engine coolant is at proper level.

If generator is mounted on a trailer, jack trailer up and

place on blocks so tires do not touch the ground or block

and completely remove the tires.

TRAILER MAINTENANCE

TRAILER MAINTENANCE

This section is intended to provide the user with generic

trailer service and maintenance information. The service

and maintenance guidelines referenced in this section refer

to a wide range of trailers.

Remember periodic inspection of the trailer will ensure safe

towing of the generator and will prevent personal injury and

damage to the equipment.

The definitions below describe some of the major

components of a typical trailer that would be used with

generator.

1. Fuel Cell — Provides an adequate amount of fuel for

the equipment in use. Fuel cells must be empty when

transporting equipment.

2. Braking System — System employed in stopping

the trailer. Typical braking systems are electric, surge,

hydraulic, hydraulic-surge and air.

3. GVWR — Gross Vehicle Weight Rating (GVWR) is

the maximum number of pounds the trailer can carry,

including the fuel cell (empty).

4. Frame Length — Measurement is from the ball hitch

to the rear bumper (reflector).

5. Frame Width — Measurement is from fender to fender

6. Jack Stand — Trailer support device with maximum

pound requirement from the tongue of the trailer.

7. Coupler — Type of hitch used on the trailer for

towing.

8. Tire Size — Indicates the diameter of the tire in

inches (10,12,14, etc.), and the width in millimeters

(175,185,205, etc.). The tire diameter must match the

diameter of the tire rim.

9. Tire Ply — The tire ply (layers) number is rated in

letters; 2-ply,4-ply,6-ply, etc.

10. Wheel Hub — The wheel hub is connected to the

trailer’s axle.

11. Tire Rim — Tires mounted on a tire rim. The tire rim

must match the size of the tire.

12. Lug Nuts — Used to secure the wheel to the wheel

hub. Always use a torque wrench to tighten down

the lug nuts. See Table 18 and Figure 60 for lug nut

tightening and sequence.

13. Axle — Indicates the maximum weight the axle can

support in pounds, and the diameter of the axle

expressed in inches. Please note that some trailers

have a double axle. This will be shown as 2-6000 lbs.,

meaning two axles with a total weight capacity of 6000

pounds.

14. Suspension — Protects the trailer chassis from shocks

transmitted through the wheels. Types of suspension

used are leaf, Q-flex, and air ride.

15. Electrical — Electrical connectors (looms) are provided

with the trailer so the brake lights and turn signals can

be connected to the towing vehicle.

16. Application — Indicates which units can be employed

on a particular trailer.

PAGE 40 — DCA45SSK/KU3 60 HZ GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (12/15/11)

TRAILER MAINTENANCE

BRAKES

Trailer brakes should be inspected the first 200 miles of

operation. This will allow the brake shoes and drums to seat

properly. After the first 200 mile interval, inspect the brakes

every 3,000 miles. If driving over rough terrain, inspect the

brakes more frequently.

Figure 58 displays the major hydraulic surge brake

components that will require inspection and maintenance.

Please inspect these components as required using steps

1 through 8 and Table 15 as listed below:

Brake Adjustment

1. Place the trailer on jack stands. Make sure the jack

stands are placed on secure level ground.

2. Check the wheel and drum for free rotation.

3. Remove the adjusting hole cover from the adjusting

slot at the bottom brake backing plate.

4. With a screwdriver or standard adjusting tool, rotate

the star wheel of the adjuster assembly to expand the

brake shoes.

5. Adjust the brake shoes outward until the pressure of

the lining against the wheel drum makes the wheel

difficult to turn.

6. Adjust, rotate the star wheel in the opposite direction

until the wheel rotates freely with slight lining drag.

7. Replace the adjusting hole cover and lower the trailer

to the ground.

8. Repeat steps 1 through 7 on the remaining brakes.

Hydraulic Surge Brakes

Hydraulic surge brakes (Figure 58) should not require any

special attention with the exception of routine maintenance

such as shoe and lining replacement. Brake lines should

be periodically checked for cracks, kinks, or blockage.

Figure 58. Hydraulic Brake Components

Actuator

Hydraulic surge braking requires the installation of an

actuator at the tongue of the trailer. Remember the surge

or push of the trailer toward the tow vehicle automatically

synchronizes the trailer brakes with the tow vehicle brakes.

As the trailer pushes against the tow vehicle the actuator

telescopes together and applies force to the master

cylinder, supplying hydraulic pressure to the trailer brakes.

Periodically check and test the surge “actuator” to make sure

that it is functioning correctly. Never use an undersize actuator.

TRAILER MAINTENANCE

TIRES/WHEELS/LUG NUTS

Tires and wheels are a very important and critical

components of the trailer. When specifying or replacing the

trailer wheels it is important the wheels, tires, and axle are

properly matched.

Tire Wear/Inflation

Tire inflation pressure is the most important factor in tire

life. Pressure should be checked cold before operation DO

NOT bleed air from tires when they are hot!. Check inflation

pressure weekly during use to insure the maximum tire life

and tread wear.

Table 16 (Tire Wear Troubleshooting) will help pinpoint the

causes and solutions of tire wear problems.

CAUTION

ALWAYS wear safety glasses when

removing or installing force fitted parts.

Failure to comply may result in serious

injury.

CAUTION

DO NOT attempt to repair or modify a

wheel. DO NOT install in inner tube to

correct a leak through the rim. If the rim

is cracked, the air pressure in the inner

tube may cause pieces of the rim to explode (break off)

with great force and cause serious eye or bodily injury.

Table 16. Tire Wear Troubleshooting

Wear Pattern Cause Solution

Center Wear Over inflation. Adjust pressure to particular

load per tire manufacturer.

Edge Wear Under inflation. Adjust pressure to particular

load per tire manufacturer.

Side Wear Loss of camber

or overloading.

Make sure load does not

exceed axle rating.

Align wheels.

Toe Wear Incorrect toe-in. Align wheels.

Cupping Out-of-balance. Check bearing adjustment

and balance tires.

Flat Spots Wheel lockup and

tire skidding.

Avoid sudden stops when

possible and adjust brakes.

Suspension

The leaf suspension springs and associated components

(Figure 59) should be visually inspected every 6,000 miles

for signs of excessive wear, elongation of bolt holes, and

loosening of fasteners. Replace all damaged parts

(suspension) immediately. Torqued suspension components

as detailed in Table 17.

Lug Nut Torque Requirements

It is extremely important to apply and maintain proper wheel

mounting torque on the trailer. Be sure to use only the

fasteners matched to the cone angle of the wheel. Proper

procedure for attachment of the wheels is as follows:

1. Start all wheel lug nuts by hand.

2. Torque all lug nuts in sequence (see Figure 60). DO

NOT torque the wheel lug nuts all the way down.

Tighten each lug nut in 3 separate passes as defined

by Table 18.
