DCA-15SPXU4 — SAFETY MESSAGE ALERT SYMBOLS

FOR YOUR SAFETY AND THE SAFETY OF OTHERS!

Safety precautions should be followed at all times when operating this equipment. Failure to read and understand the

Safety Messages and Operating Instructions could result in injury to yourself and others.

NOTE

This Owner's Manual has been developed to provide complete instructions for the safe and efficient operation of the

MQ Power Model DCA-15SPXU4

Whisperwatt™ Generator.

Before using this generator, ensure that the operating individual has read and understands all instructions in this manual.

HAZARD SYMBOLS

Potential hazards associated with the operation of this equipment will be referenced with " Hazard Symbols" which appear throughout this manual, and will be referenced in conjunction with Safety " Message Alert Symbols".

WARNING - LETHAL EXHAUST GASES

Gasoline engine exhaust gases contain poisonous carbon monoxide. This gas is colorless and odorless, and can cause

DEATH if inhaled. NEVER operate this equipment in a confined area or enclosed structure that does not provide ample free flow air.

SAFETY MESSAGE ALERT SYMBOLS

The three (3) Safety Messages shown below will inform you about potential hazards that could injure you or others. The

Safety Messages specifically address the level of exposure to the operator, and are preceded by one of three words:

DANGER, WARNING, or CAUTION.

DANGER

You WILL be KILLED or SERIOUSLY injured if you do not follow directions.

WARNING - EXPLOSIVE FUEL

Diesel fuel is extremely flammable, and its vapors can cause an explosion if ignited. DO NOT start the engine near spilled fuel or combustible fluids.

DO NOT fill the fuel tank while the engine is running or hot.

DO NOT overfill tank, since spilled fuel could ignite if it comes into contact with hot engine parts or sparks from the ignition system. Store fuel in approved containers, in well-ventilated areas and away from sparks and flames.

NEVER use fuel as a cleaning agent.

WARNING

You COULD be KILLED or SERIOUSLY injured if you do not follow directions.

CAUTION

You CAN be injured if you do not follow directions

WARNING - BURN HAZARDS

Engine components can generate extreme heat. To prevent burns, DO NOT touch these areas while the engine is running or immediately after operations. NEVER operate the engine with heat shields or heat guards removed.

DANGER - ELECTROCUTION HAZARDS

During operation of this generator, there exists the possibility of electrocution,

electrical shock or burn, which can cause

severe bodily harm or even DEATH!


DCA-15SPXU4 — SAFETY MESSAGE ALERT SYMBOLS

CAUTION - RESPIRATORY HAZARDS WARNING - ROTATING PARTS

NEVER operate equipment with covers, or guards removed. Keep fingers, hands,

hair and clothing away from all moving parts to prevent injury.

ALWAYS wear approved respiratory protection.

CAUTION - ACCIDENTAL STARTING

ALWAYS place the engine ON/OFF switch (MPEC) in the OFF/RESET position when the generator is not in use.

CAUTION - SIGHT AND HEARING HAZARDS

ALWAYS wear approved eye and

hearing protection.

CAUTION - OVER-SPEED CONDITIONS

NEVER tamper with the factory settings of the engine governor or settings.

Personal injury and damage to the engine or equipment can result if operating in speed ranges above maximum allowable.

NOTE

CAUTION - EQUIPMENT DAMAGE MESSAGES

Other important messages are provided throughout this manual to help prevent damage to your generator, other property, or the surrounding environment.

This generator, other property, or the surrounding environment could be damaged if you do not follow instructions.

CAUTION - ENGINE LOAD (WET-STACKING)

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 sufficient 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 turbocharges, and reduce the operating performance.

In order for a diesel engine to operate at peak efficiency 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 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.

DCA-15SPXU4 — INSTALLATION

Figure 2. Typical Generator Grounding Application


DCA-15SPXU4 — 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.

CAUTION - EXHAUST HAZARD

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.

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.

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 - 10 AWG (5.3 mm 2 ) or larger.

b. Aluminum - 8 AWG (8.4 mm 2 ) or larger.

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(c) specifies that the earth ground rod should be buried aminimum of 8 ft. into the ground.

NOTE

When connecting the generator to any buildings electrical system ALWAYS consult with a licensed electrician.

Water Heater (Optional)

Open Delta Excitation System

The 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

The DCA-15SPXU4 is powered by a 4 cylinder, water cooled,

Kubota Model V2203-M diesel engine. This engine is designed to meet every performance requirement for the generator. Reference Table 1 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

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.

Connecting Loads

Loads can be connected to the generator by the Ouput

Terminal Lugs or the convenience receptacles (Figure 11).

Make sure to read the operation manual before attempting to connect a load to the generator.

To protect the output terminals from overload, a

3-pole, 70A main circuit breaker is provided. Make sure to switch ALL circuit breakers to the OFF position prior to starting the engine.

Figure 11. Connecting Loads


DCA-15SPXU4 — LOAD APPLICATION/MAXIMUM AMPERAGE

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.

NOTE

Motors and motor-driven equipment draw much greater current for starting than during operation.

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.

NOTE

If wattage is not given on the equipment's name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage.

WATTS = VOLTAGE x AMPERAGE

The power factor of this generator is 0.8. See Table 5 below when connecting loads.

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.

Coolant (Antifreeze/Summer Coolant/Water)

KUBOTA recommends antifreeze/summer coolant for use in their engines, which can be purchased in concentrate (and mixed with 50% demineralized water) or pre-diluted. See the KUBOTA Engine Owner's Manual for further details.

Cleaning the Radiator

The engine may overheat if the radiator fins become overloaded with dust or debris. Periodically clean the radiator fins with compressed air. Cleaning inside the machine is dangerous, so clean only with the engine turned off and the

negative battery terminal disconnected.

Air Cleaner

Periodic cleaning/replacement is necessary. Inspect it in accordance with the KUBOTA Engine Owner's Manual.


If adding coolant/antifreeze mix to the radiator, DO NOT remove the radiator cap until the unit has completely cooled. The possibility of hot! coolant exists which can cause severe burns.

Day-to-day addition of coolant is done from the recovery tank. When adding coolant to the radiator, DO NOT remove the radiator cap until the unit has completely cooled. See

Table 9 for engine, radiator, and recovery tank coolant capacities. Make sure the coolant level in the recovery tank is always between the "H" and the "L" markings.

Fan Belt Tension

A slack fan belt may contribute to overheating, or to insufficient charging of the battery. Inspect the fan belt for damage and wear and adjust it in accordance with the

KUBOTA Engine Owner's Manual.

The fan belt tension is proper if the fan belt bends 10 to 15 mm (Figure 23) when depressed with the thumb as shown below.

Always maintain battery fluid level between the specified marks. Battery life will be shortened, if the fluid level are not properly maintained. Add only distilled water when replenishment is necessary.

DO NOT over fill. Check to see whether the battery cables are loose. Poor contact may result in poor starting 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 24) 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.

CAUTION - BATTERY SERVICING SAFETY

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 ignition switch is in the ON position

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.

NOTE

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 - BATTERY SERVICING SAFETY

Inadequate battery connections may cause poor starting of the generator, and create other malfunctions.

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 corrision and damage the alternator.

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 11 as a general engine maintenance guideline (Refer to the Engine Instruction

Manual).

Air Cleaner

Every 250 hours: Remove air cleaner element and clean the heavy duty paper element with light spray of compressed air. Replace the air cleaner as needed.

Air Cleaner with Dust Indicator (If Equipped)

This indicator 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.

Service Daily

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.



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. This unit is equipped with an automatic air bleeding system.

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 17.

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.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove dust or water in the strainer cap and wash it in gasoline.

Securely fasten the fuel strainer cap so that fuel will not leak. Check the fuel strainer every 200 hours of operation or once a month.

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.

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.

 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.

 Tighten both cocks and replace the overflow tank.

 Replace with coolant as recommended by the engine manufaturer.

 Close radiator cap tightly.


Allow engine to steam.

cool when flushing out radiator. Flushing the radiator while hot could cause serious burns from water or

Generator Storage

For longe term storage of the generator the following is recommended:

 Fill 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.

Jacket Water Heater and Internal Battery Charger

120 VAC Input Receptacles (OPTIONAL)

This generator can be optionally equipped with two 120 VAC,

20 amp input receptacles located on the output terminal panel.

The purpose of these receptacles is to provide power via commercial power to the jacket water heater and internal

battery charger.

These receptacles will ONLY function when commercial power has been supplied to them (Figure 36). To apply commercial power to these receptacles, a power cord of adequate size will be required (See Table 6).

When using the generator in hot climates there is no reason to apply power to jacket water heater. However, if the generator will be used in cold climates it is always a good idea to apply power to the jacket water heater at all times. To apply power to the jacket water heater simply apply power to the jacket water heater receptacle via commercial power using an power cord of adequate size.


If the generator will be used daily, the battery should normally not require charging. If the generator will be idle (not used) for long periods of time, apply power to the battery charger receptacle via commercial power using an power cord of adequate size.

NOTE

To ensure adequate starting capability, always have power applied to the generator's

internal battery charger.

DCA-15SPXU4 — 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 37 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 12 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 37) 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 37. 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.

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.

Suspension

The leaf suspension springs and associated components

(Figure 38) 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 14.

CAUTION - EYESIGHT HAZARD

ALWAYS wear safety glasses when removing or installing force fitted parts.

Failure to comply may result in serious injury.

CAUTION - REPAIRING TRAILER WHEELS

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.

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 13 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

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 39). DO NOT torque the wheel lug nuts all the way down. Tighten each lug nut in 3 separate passes as defined by Table 15.

3. After first road use, retorque all lug nuts in sequence.

Check all wheel lug nuts periodically.
