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 shor t 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

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 ar ticles 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.

INDOOR INSTALLATION

Exhaus t gas es 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.

3. NEC article 250-52(c) 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.

MQP240 GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (10/23/12) — PAGE 15

GENERAL INFORMATION

GENERATOR

The MQP240 generator (Figure 3) is designed as a high quality portable (requires a trailer for transport) power source for telecom sites, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

ENGINE OPERATING PANEL

The “Engine Operating Panel” is provided with the following:

 Tachometer  Emergency Stop Switch  Water Temperature Gauge  Oil Pressure Gauge  Charging Ammeter Gauge  Fuel Level Gauge  Engine Speed Switch  Battery Switch  Engine Alarm Lamps (4)

GENERATOR CONTROL PANEL

The “Generator Control Panel” is provided with the following:

 Frequency Meter (Hz)  AC Ammeter (Amps)  AC Voltmeter (Volts)  Ammeter Change-Over Switch  Voltmeter Change-Over Switch  Voltage Regulator  Panel Light/Panel Light Switch  3-Pole, 800 amp Main Circuit Breaker  “Control Box” (located behind the Gen. Control Panel)

• Automatic Voltage Regulator

• Current Transformer

• Over-Current Relay

• Starter Relay

• Engine Controller (Computer Controlled)

OUTPUT TERMINAL PANEL

The “Output Terminal Panel” is provided with the following:

 Three 120/240V output receptacles (CS-6369), 50A  Three auxiliary circuit breakers, 50A  Two 120V output receptacles (GFCI), 20A  Two GFCI circuit breakers, 20A  Eight output terminal lugs (3Ø power)  Battery Charger (Optional)  Water Heater (Optional)

OPEN DELTA EXCITATION SYSTEM

Each generator is equipped with the state of the art “OpenDelta” 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

Both generators are powered by a 6 cylinder, 4-cycle water cooled, direct injection, turbocharged, charge air cooled

Cummins QSL9-G3 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

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.

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.

WATTS = VOLTAGE x AMPERAGE

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

THREE PHASE LOAD

When calculating the power requirements for 3-phase power use the following equation:

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

NOTICE

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.

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 12 as a general maintenance guideline Engine Side (Refer to the Engine Instruction Manual)

AIR CLEANER

Every 250 hours: Remove air cleaner element (Figure 55) 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 55) 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 55. 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 38 —MQP240 GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (10/23/12)

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

Drain the fuel inside the fuel tank completely. Using a spray washer (Figure 56) wash out any deposits or debris that have accumulatedi inside the fuel tank.

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

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 Cummins Engine Manual for details.

FUEL TANK

Figure 56. Fuel Tank Cleaning

MQP240 GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (10/23/12) — PAGE 39

MAINTENANCE

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 27.

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.

RADIATOR CLEANING

The radiator (Figure 57) 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 57. 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.

 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.

WARNING

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

PAGE 40 —MQP240 GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (10/23/12)

 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.

MAINTENANCE

JACKET WATER HEATER AND INTERNAL BATTERY CHAR G ER 120 VAC IN P UT RECEP TACL E S (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 58). 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 a power cord of adequate size.

NOTICE

To ensure adequate starting capability, always have power applied to the generator's internal battery charger..

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 the 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).

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 16 and Figure 61 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.

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.

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 42 —MQP240 GENERATOR • OPERATION AND PARTS MANUAL — REV. #0 (10/23/12)

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 59 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 13 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 59) 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 59. 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 ver y impor tant and critical components of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are properly matched.

CAUTION

ALWAYS wea r safety glasse s 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.

Tire Wear/Inﬂation

Suspension

The leaf suspension springs and associated components (Figure 60) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged par ts (suspension) immediately. Torqued suspension components as detailed in Table 15.

Figure 60. Major Suspension Components

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

Table 14. Tire Wear Troubleshooting

Wear Pattern Cause Solution

Center Wear Over inﬂation.

Edge Wear Under inﬂation.

Side Wear

Toe Wear Incorrect toe-in. Align wheels.

Cupping Out-of-balance.

Flat Spots

Loss of camber or overloading.

Wheel lockup and tire skidding.

Adjust pressure to particular load per tire manufacturer.

Make sure load does not exceed axle rating. Align wheels.

Check bearing adjustment and balance tires.

Avoid sudden stops when possible and adjust brakes.

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 61). DO NOT torque the wheel lug nuts all the way down. Tighten each lug nut in 3 separate passes as deﬁned by Table 16.

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