ALWAYS wear approved eye andhearing protection.

Other important messages are provided throughout thismanual to help prevent damage to your generator, otherproperty, or the surrounding environment.

This generator, other property,or the surrounding environmentcould be damaged if you do notfollow instructions.

NOTE

NEVER tamper with the factory settingsof the engine governor or settings.Personal injury and damage to the engineor equipment can result if operating inspeed ranges above maximum allowable.

CAUTION - OVER-SPEED CONDITIONS

CAUTION - ACCIDENTAL STARTING

CAUTION - RESPIRATORY HAZARDS

CAUTION - SIGHT AND HEARING HAZARDS

CAUTION - EQUIPMENT DAMAGE MESSAGES

NEVER operate equipment with covers,or guards removed. Keep fingers,hands, hair and clothing away from allmoving parts to prevent injury.

WARNING - ROTATING PARTS

Wet-Stacking is a common problem with diesel engineswhich are operated for extended periods with light or noload applied. When a diesel engine operates withoutsufficient load (less than 40% of the rated output) it willnot operate at its optimum temperature. This will allowunburned fuel to accumulate in the exhaust system, whichcan foul the fuel injectors, engine valves and exhaustsystem, including turbocharges, and reduce the operatingperformance.In order for a diesel engine to operate at peak efficiency itmust be able to provide fuel and air in the proper ratio andat a high enough engine temperature for the engine tocompletely burn all of the fuel.Wet stacking does usually cause any permanent damageand can be alleviated if additional load is applied to relievethe condition. It can reduce the system performance andincrease maintenance. Applying an increasing load overa period of time until the excess fuel is burned off and thesystem capacity is reached usually can repair the condition.This can take several hours to burn off the accumulatedunburned fuel.

CAUTION - ENGINE LOAD (WET-STACKING)

Figure 2. Typical Generator Grounding Application

DCA10SPX4/DCA10SPXU4 — INSTALLATION


1

Outdoor Installation

Install the generator in a area that is free of debris,bystanders, and overhead obstructions. Make sure thegenerator is on secure level ground so that it cannot slide orshift around. Also install the generator in a manner so thatthe exhaust will not be discharged in the direction of nearbyhomes.

The installation site must be relatively free from moistureand dust. All electrical equipment should be protected fromexcessive moisture. Failure to do will result in deteriorationof the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasivematerials have a tendency to cause excessive wear toengine and alternator parts.

Generator Grounding

To guard against electrical shock and possible damage tothe equipment, it is important to provide a good EARTHground.

Article 250 (Grounding) of the National Electrical Code(NEC) provides guide lines for proper grounding andspecifies that the cable ground shall be connected to thegrounding system of the building as close to the point ofcable entry as practical.

NEC articles 250-64(b) and 250-66 set the followinggrounding requirements:

1. Use one of the following wire types to connect thegenerator to earth ground.

a. Copper - 10 AWG (5.3 mm2) or larger.

b. Aluminum - 8 AWG (8.4 mm2) or larger.

2. When grounding the generator (Figure 2) connect theground cable between the lock washer and the nut onthe generator and tighten the nut fully. Connect the otherend of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth groundrod should be buried aminimum of 8 ft. into the ground.

When connecting the generatorto any buildings electricalsystem ALWAYS consult witha licensed electrician.

DCA10SPX4/DCA10SPXU4 — INSTALLATION

NOTE

Indoor Installation

Exhaust gases from diesel engines are extremely poisonous.Whenever an engine is installed indoors the exhaust fumesmust be vented to the outside. The engine should be installedat least two feet from any outside wall. Using an exhaustpipe which is too long or too small can cause excessive backpressure which will cause the engine to heat excessivelyand possibly burn the valves.

Mounting

The generator must be mounted on a solid foundation (suchas concrete) and set firmly on the foundation to isolatevibration of the generator when it is running. The generatormust set at least 6 inches above the floor or grade level (inaccordance to NFPA 110, Chapter 5-4.1). DO NOT removethe metal skids on the bottom of the generator. They are toresist damage to the bottom of the generator and to maintainalignment.

Pay close attention to ventilation when operating thegenerator inside tunnels and caves. The engine exhaustcontains noxious elements. Engine exhaust must be routedto a ventilated area.

CAUTION - EXHAUST HAZARD


DCA10SPX4/DCA10SPXU4 — GENERAL INFORMATIONDCA-10SPX4 Whisperwatt™ Series FamiliarizationGeneratorThe MQ Power Model DCA10SPX4 is a 8 kW generator(Figure 3) that is designed as a high quality portable (requiresa trailer for transport) power source for telecom sites, lightingfacilities, power tools, submersible pumps and other industrialand construction machinery.Generator Control PanelThe “Engine Operating Panel” is provided with the following:

Open Delta Excitation SystemThe generator is equipped with the state of the art "Open-Delta" excitation system. The open delta system consist ofan electrically independent winding wound among stationarywindings 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 voltageregulator is supplied from the parallel connections of A to B,A to D, and C to D. These three phases of the voltage inputto the voltage regulator are then rectified and are theexcitation current for the exciter section.When a heavy load, such as a motor starting or a shortcircuit occurs, the automatic voltage regulator (AVR) switchesthe configuration of the open delta to the series connectionof B to C. This has the effect of adding the voltages of eachphase to provide higher excitation to the exciter section andthus better voltage response during the application of heavyloads.The connections of the AVR to the AC output windings arefor sensing only. No power is required from these windings.The open-delta design provides virtually unlimited excitationcurrent, offering maximum motor starting capabilities. Theexcitation does not have a "fixed ceiling" and respondsaccording the demands of the required load.EngineThe DCA-10SPX4 is powered by a 3 cylinder, water cooled,Kubota Model D1503-M diesel engine. This engine isdesigned to meet every performance requirement for thegenerator. Reference Table 2 for engine specifications.In keeping with MQ Power's policy of constantly improvingits products, the specifications quoted herein are subject tochange without prior notice.Electric Governor SystemThe electric governor system controls the RPMs of the en-gine. When the engine demand increases or decreases,the governor system regulates the frequency variation to±.25%.Extension CablesWhen electric power is to be provided to various tools orloads at some distance from the generator, extension cordsare normally used. Cables should be sized to allow fordistance in length and amperage so that the voltage dropbetween the generator and point of use (load) is held to aminimum. Use the cable selection chart (Table 6) as a guidefor selecting proper extension cable size.

DCA10SPX4/DCA10SPXU4 — LOAD APPLICATION/MAXIMUM AMPSSingle Phase Load

Always be sure to check the nameplate on the generatorand equipment to insure the wattage, amperage, frequency,and voltage requirements are satisfactorily supplied by thegenerator for operating the equipment.

Generally, the wattage listed on the nameplate of theequipment is its rated output. Equipment may require 130—150% more wattage than the rating on the nameplate, asthe wattage is influenced by the efficiency, power factor andstarting system of the equipment.

Motors and motor-drivenequipment draw much greatercurrent for starting than duringoperation.

When connecting ordinary power tools, a capacity of up tothe generating set’s rated output (kW) multiplied by 0.8 canbe used.

If wattage is not given on theequipment's name plate,approximate wattage may bedetermined by multiplyingnameplate voltage by thenameplate amperage.

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

■■■■■ When connecting a resistance load such as anincandescent lamp or electric heater, a capacity of upto the generating set’s rated output (kW) can be used.

■■■■■ When connecting a fluorescent or mercury lamp, acapacity 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 currentcapacity.

WATTS = VOLTAGE x AMPERAGE

NOTE

An inadequate size connecting cable which cannot carrythe required load can cause a voltage drop which can burnout the appliance or tool and overheat the cable. See Table6.

NOTE

Before connecting this generator to any building’s electricalsystem, a licensed electrician must install an isolation(transfer) switch. Serious damage to the building’selectrical system may occur without this transfer switch.

DCA10SPX4/DCA10SPXU4 — MAINTENANCE

Service Daily

If the engine is operating in very dusty or dry grassconditions, a clogged air cleaner will result. This can lead toa loss of power, excessive carbon buildup in the combustionchamber and high fuel consumption. Change air cleanermore frequently if these conditions exists.

Fuel Addition

Add diesel fuel (the grade may vary according to seasonand locations).

Removing Water from the Fuel Tank

After prolonged use, water and other impurities accumulatein the bottom of the tank. Occasionally inspect the fueltank for water contamination and drain the contents ifrequired.

During cold weather, the more empty volume inside thetank, the easier it is for water to condense. This can bereduced by keeping the tank full with diesel fuel.

General Inspection

Prior to each use, the generator should be cleaned andinspected for deficiencies. Check for loose, missing ordamaged nuts, bolts or other fasteners. Also check for fuel,oil, and coolant leaks. Use Table 11 as a general enginemaintenance guideline (Refer to the Engine InstructionManual).

Air Cleaner

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

DCA10SPX4/DCA10SPXU4 — MAINTENANCE

Generator Storage

For longe term storage of the generator the following isrecommended:

Fill the fuel tank completely. Treat with a fuel stabilizer ifnecessary.

Completely drain the oil from the crankcase and refill ifnecessary 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 andplace on blocks so tires do not touch the ground or blockand completely remove the tires.

Flushing Out Radiator and Replacing Coolant

Open both cocks located at the crankcase side and atthe lower part of the radiator and drain coolant. Openthe radiator cap while draining. Remove the overflowtank and drain.

Check hoses for softening and kinks. Check clamps forsigns of leakage.

Flush the radiator by running clean tap water throughradiator until signs of rust and dirt are removed. DO NOTclean radiator core with any objects, such as ascrewdriver.

Tighten both cocks and replace the overflow tank.

Replace with coolant as recommended by the enginemanufaturer.

Close radiator cap tightly.

Air Removal

If air enters the fuel injection system of a diesel engine,starting becomes impossible. After running out of fuel, orafter disassembling the fuel system, bleed the systemaccording to the following procedure. See the KUBOTAEngine 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. Thisunit is equipped with an automatic air bleeding system.

Check Oil Level

Check the crankcase oil level prior to each use, or when thefuel tank is filled. Insufficient oil may cause severe damageto the engine. Make sure the generator is level. The oil levelmust be between the two notches on the dipstick as shownin Figure 12.

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 oilwill drop slightly. Run the engine for a while and checkfor leaks before adding more oil if needed. Cleanexcessive oil from engine.

Allow engine to cool when flushing outradiator. Flushing the radiator while hotcould cause serious burns from water orsteam.


Replacing Fuel Filter

Replace the fuel filter cartridge with new one every 500hours or so.

Loosen the drain plug at the lower top of the fuel filter.Drain the fuel in the fuel body together with the mixedwater. DO NOT spill the fuel during disassembly.

Vent any air.

Cleaning the Fuel StrainerClean the fuel strainer if it contains dust or water. Removedust 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 oncea month.


DCA10SPX4/DCA10SPXU4 — TRAILER MAINTENANCEHydraulic Surge BrakesHydraulic surge brakes (Figure 31) should not require anyspecial attention with the exception of routine maintenancesuch as shoe and lining replacement. Brake lines should beperiodically checked for cracks, kinks, or blockage.

Figure 31. Hydraulic Brake Components

BrakesTrailer brakes should be inspected the first 200 miles ofoperation. This will allow the brake shoes and drums to seatproperly. After the first 200 mile interval, inspect the brakesevery 3,000 miles. If driving over rough terrain, inspect thebrakes more frequently.

Figure 31 displays the major hydraulic surge brakecomponents that will require inspection and maintenance.Please inspect these components as required using steps 1through 8 and Table 12 as listed below:

Brake Adjustment

1. Place the trailer on jack stands. Make sure the jackstands are placed on secure level ground.

2. Check the wheel and drum for free rotation.

3. Remove the adjusting hole cover from the adjusting slotat the bottom brake backing plate.

4. With a screwdriver or standard adjusting tool, rotate thestar wheel of the adjuster assembly to expand the brakeshoes.

5. Adjust the brake shoes outward until the pressure ofthe lining against the wheel drum makes the wheeldifficult to turn.

6. Adjust, rotate the star wheel in the opposite directionuntil the wheel rotates freely with slight lining drag.

7. Replace the adjusting hole cover and lower the trailer tothe ground.

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

ActuatorHydraulic surge braking requires the installation of anactuator at the tongue of the trailer. Remember the surge orpush of the trailer toward the tow vehicle automaticallysynchronizes the trailer brakes with the tow vehicle brakes.As the trailer pushes against the tow vehicle the actuatortelescopes together and applies force to the master cylinder,supplying hydraulic pressure to the trailer brakes.

Periodically check and test the surge “actuator” to makesure that it is functioning correctly. Never use an undersizeactuator.
