WARNING!

Only a qualified electrician may service or make connections

to the generator. Lethal voltage is present at the connection

lugs when the generator is running!

OPERATING SAFETY

Before using the generator be sure you read and understand all instructions! Equipment operated

improperly or by untrained personnel can be dangerous! Read the operating instructions and familiarize

yourself with the location and proper use of all instruments and controls. Inexperienced operators should

receive instruction from someone familiar with the equipment before being allowed to operate or set up the

generator.

The area immediately surrounding the generator should be clean, neat, and free of debris.

Position and operate generator tower on a firm, level surface.

NEVER start a unit in need of repair.

NEVER modify the generator or use it in a manner other than what it was designed for.

ALWAYS keep the generator doors closed when the engine is running. Do not start the generator if any

panels or guards are loose or missing.

ALWAYS connect the generator to a good earthen ground.

Move the generator main circuit breaker to the “OFF” position when servicing or troubleshooting the unit.

 The output voltage of the generator can cause a fatal electric shock. Avoid contact with any alternating

current wiring when the engine is running. Make sure any extension cords or equipment connected to

the convenience outlets are in good working condition.

 NEVER remove control box cover when the engine is running. Exposed live electrical terminals can

cause a fatal electrical shock.

 Check your electrical requirements before installing or starting the generator.

Use a ground fault circuit interrupter (GFCI) in damp or highly conductive areas and construction sites

to prevent electrical shock.

ENGINE SAFETY

Internal combustion engines present special hazards during operation and fueling! Failure to follow the

safety guidelines described below could result in severe injury or death. Also read and follow all safety

warnings described in the Engine Operator's Manual. A copy of this manual was supplied with unit when

it was shipped from the factory.

 DO NOT run engine indoors or in an area with poor ventilation unless exhaust hoses are used.

 DO NOT fill fuel tank near an open flame, while smoking, or while engine is running.

 DO NOT fill tank in an enclosed area with poor ventilation.

 DO NOT touch or lean against hot exhaust pipes or engine cylinder.

 DO NOT operate with the fuel tank cap loose or missing.

 DO NOT remove engine coolant cap while engine is hot.

 DO NOT clean air filter with gasoline or other types of low flash point solvents.

Keep area around exhaust pipes and air ducts free of debris to reduce the chance of an accidental fire.

 Shut the engine down if any of the following conditions exist during operation:

A. Noticeable change in engine speed.

B. Loss of electrical output.

C. Equipment connected to the generator overheats.

D. Sparking occurs.

E. Engine misfires or there is excessive engine/generator vibration.

TOWING SAFETY

Towing a trailer requires care! Both the trailer and vehicle must be in good condition and securely fastened to

each other to reduce the possibility of an accident. Also, some states require that large trailers be registered

and licensed. Contact your local Department of Transportation office to check on license requirements for your

particular unit.

Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's "gross

vehicle weight rating" (GVWR). Check tires on trailer for tread wear, inflation, and condition.

 Inspect the hitch and coupling for wear or damage. DO NOT tow trailer using defective parts!

 Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely fastened

to the vehicle.

Connect safety chains in a crossing pattern under the tongue and attach the brake away cable TO THE

REAR BUMPER OF THE TOWING VEHICLE.

 Make sure directional and brake lights on the trailer are connected and working properly.

 Check that lug nuts holding wheels are tight and that none are missing.

 Maximum recommended speed for highway towing is 45 m.p.h.. Recommended off-road towing speed

is not to exceed 10 m.p.h. or less depending on terrain.

When towing, maintain extra space between vehicles and avoid soft shoulders, curbs and sudden lane

changes. If you have not pulled a trailer before, practice turning, stopping, and backing up in an area away

from heavy traffic.

A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler clean and

apply fresh grease each time the trailer is towed.

GENERATOR OUTPUT CONNECTION LUGS

The generator is equipped with connection lugs behind a door below the controller face. The lugs provide

connection points for attachment of external loads to the generator. A large decal on the inside of the

connection lug door details the proper connections for selected voltages.

Connections to the lugs should be made by running the power cables through the circular plastic bushing

on the lower right side of the control box. DO NOT make any connections directly to the lug without routing

the cables through this bushing. The connection lug door is equipped with a safety interlock switch that will

automatically trip the main circuit breaker and disable the voltage regulator when the lug door is opened.

Use a 5/16” hex-wrench to tighten the cable connections.

A ground connection is located next to the connection lugs. The unit MUST HAVE this ground lug con-

nected to a good earthen ground for proper operating safety. The ground connection SHOULD BE IN

COMPLIANCE WITH THE NATIONAL ELECTRIC CODE (NEC) AS WELL AS ANY STATE OR LOCAL

GUIDELINES OR CODES.

WARNING!

It is HIGHLY RECOMMENDED that only a trained and licensed electri-

cian perform any wiring and related connections to the generator. Instal-

lation should be in compliance with the NATIONAL ELECTRIC CODE

(NEC) as well as any local or state guidelines as required by law. Failure

to follow proper installation requirements may result in equipment or

property damage, personal injury or death.

WARNING!

Before any connections are made to the generator, make sure that the

main circuit breaker and the control power switch are in the OFF “O”

position. Potentially lethal voltages may be present at the generator

connection lugs.

WARNING!

Improper or incorrect connections to a buildings electrical system can

cause potentially lethal voltages to backfeed onto utility lines. This

may result in injury or electrocution to utility workers nearby. Make

sure the generator is suppling power to an isolated object or building

that is not connected to any utility lines.

VOLTAGE SELECTOR SWITCH

The voltage selector switch is located on a panel attached to the generator behind the door located next to

the fuel tank filler. The selector switch is a three position switch that mechanically changes the connec-

tions between the generator output leads and the connection lugs on the main control panel. Voltage

ranges are selected by rotating the handle on the switch to the desired voltage.

The voltage switch is equipped with a locking mechanism. Once the proper voltage has been selected,

push the red latch on the inside of the phase switch handle up and insert a padlock through the handle. By

locking the handle in place you will prevent unauthorized personnel from changing the switch settings.

NOTE: When the voltage selector switch is in position for 480/277V 3O, voltage at the two GFCI duplex

convenience outlets is 139 Volts and the voltage at the three twist-lock outlets is 240/139 Volts. When the

voltage selector switch is in position for 208/120V 3O, voltage at the three twist-lock outlets and the two

GFCI outlets is 208/120 volts.

AUXILIARY OUTLETS

The control panel is equipped with six outlets for

running accessories or tools from the generator.

Power is supplied to the outlets any time the en-

gine is running and the main circuit breaker and

the auxiliary outlet main circuit breaker are switched

on “I”.

Should the main breaker trip, or the auxiliary out-

let main circuit breaker trip, remove some of the

load to the outlets before turning them back on.

Note: To ensure proper grounding, anytime the

generator is providing power to any equipment or

load panels that do not have a grounded plug a

ground wire must be added between the equipment and the grounding stud on the outlet panel per any

local, state or NEC codes and guidelines.

VOLTAGE REGULATION

System stability is the ability of the generator to respond to load transients. Decreasing stability makes the

generator less sluggish and faster to respond to load transients. If the stability of the regulator is de-

creased too much, the generator will tend to hunt under steady state conditions. To adjust the regulation,

see the included manual for the voltage regulator. The regulator is located behind the control panel on the

back of the generator box.

FINE VOLTAGE ADJUSTMENT

The output voltage can be fine adjusted after the generator is running by using the fine voltage adjustment

knob. The switch is located directly below the control power switch next to the control panel. This rheostat

will provide an increase (“+”) or a decrease (”-”) in the output voltage. To adjust the voltage, check the

output voltage on the LCD display. Turn the knob in the desired direction until the required voltage is shown

on the LCD display.

EMERGENCY STOP SWITCH

The generator is equipped with one emergency stop switch,

located on the side panel next to the auxiliary outlet panel.

The switch is clearly labeled with “EMERGENCY STOP” and

is red in color. The switch can be accessed and activated

with all doors closed and locked.

Activate the emergency stop switch by pushing the red but-

ton in until it locks down. This will trip the main circuit breaker

which will open the contact disconnecting the load to the con-

nection lugs. This will also open the fuel pump solenoid, shut-

ting down the engine and the Emergency Stop fault will be

displayed on the LCD. The switch will remain closed until it is

pulled out.

CAUTION! Use the EMERGENCY STOP only when the generator must be shut down immediately.

For any other shut down, follow the detailed shut down procedure.

AUXILIARY OUTLET

GROUNDING STUD

MAIN CIRCUIT BREAKER

The main circuit breaker is located on the main control panel. When the breaker is in the off “O” position,

power is interrupted between the customer connection lugs and the generator. Once the connections

have been made to the connection lugs and the generator has been started and allowed to reach normal

operating temperature, the breaker may be switched to the on “I” position.

The main circuit breaker will be tripped, disconnecting power to the connection lugs, if any of the following

items occur while the unit is running:

1. Overload of the generator circuits to the connection lugs.

2. The door covering the customer connection lugs is opened.

3. If the emergency stop switch is activated.

Make sure that any problems that caused the main circuit breaker to trip are corrected before returning the

switch to the on “I” position.

REMOTE START TERMINAL BLOCK

The remote start terminal block is located under the lug box door just below the voltage selector switch. It

provides a connection for installation of a remote start switch which will allow the generator to be started by

a remote dry-contact closure switch.

Before pressing the “AUTO” button, verify that the contacts on any remote switch linked to the generator

are OPEN. If the contacts on a remote switch are closed, the generator will crank and start when AUTO is

selected on the controller. Attach the switch leads to the two unused terminals on the generators remote

start block. For additional information on starting the generator, see GENERATOR START UP section of

this manual.

When the generator is used as a standby power supply, it must be equipped with a transfer switch which

isolates it from the utility’s distribution system. A transfer switch is designed to transfer electrical

loads from the normal power source (utility) to the emergency power source (generator) when normal

voltage falls below a prescribed level. The transfer switch automatically returns the load back to the

normal source when power is restored back to operating levels.

WARNING!

Failure to isolate the generator from the normal power utility can cause

potentially lethal voltage to backfeed into the utility lines. This may result in

injury or electrocution of utility workers nearby. Make sure that the generator

is isolated by a transfer switch from any local utility lines. This also applies if

the generator is being used as a back up to some other type of power supply.

WARNING!

THE MAIN CIRCUIT BREAKER INTERRUPTS POWER TO THE CUSTOMER

CONNECTION LUGS ONLY. THE CUSTOMER CONVENIENCE OUTLETS HAVE

POWER EVEN IF THE MAIN CIRCUIT BREAKER IS IN THE OFF “O” POSITION.

The auxiliary outlet main circuit breaker, located next to the main circuit breaker,

will disconnect all power to the auxiliary outlet panel.

Installation of a transfer switch or other type of remote starting device is the responsibility of the generator

user. Installation of such devices must be performed by following all directions supplied by the manufac-

turer of the switch. If attaching generator to a power supply normally serviced by a utility company, notify

the utility company and check local and state regulations. Familiarize yourself with all instructions and

warning labels supplied with the switch.

regulations. Failure to follow these procedures could result in property

damage, personal injury or death. Before any connections are attempted,

make sure the main circuit breaker and the engine start switch are in the

OFF “O” position.

WARNING!

When using the generator as a stand by or substitute power supply, make sure

the output voltage and phase rotation of the generator match those of the

local power utility. Improper voltage or phase rotation may cause equipment

damage or malfunction.

Once the generator is at normal operating temperature, check the generator for excessive noise, vibration

and coolant, oil or fuel leaks before applying any loads.

12. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the fine

voltage adjustment switch, described on page 16.

13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency

should read approximately 60-62 Hz, depending on the type of engine governing used.

14. If all wiring connections have been done correctly, switch the main circuit breaker to the on “I” position

and then add any loads attached to the convenience outlets by switching the respective circuit breaker

to the ON “I” position. You will notice a slight change in engine noise.

AUTO (REMOTE) STARTING OF THE GENERATOR

The AUTO button is used when the generator is started from a location other than the control panel by

using a remote start switch or transfer switch. AUTO (remote start) is the normal setting when the genera-

tor is being used as a standby power supply. Before putting the generator in the AUTO (remote start)

mode, review the PRE-START CHECK LIST and MANUAL STARTING OF THE GENERATOR sections

beginning on page 18. Also follow all safety warnings and information on isolating the generator with a

transfer switch if the unit is to be used as a standby power supply on pages 16 and 17. Then continue with

the steps described below:

1. Perform a manual start of the generator at least once to verify that the engine is operating correctly.

2. If a check of the remote start circuit is desired, press the “AUTO” button. The LCD display should high-

light “AUT” in the upper left corner. Attach a jumper wire (minimum 16 gauge) equipped with two

alligator clips across the two unused terminals on the remote start terminal block. This applies a

ground to the EZ-1 to close the starting circuit. The engine should crank, start and run.

3. Remove the jumper wire from the remote start terminal block, the engine will stop. Connect any nec-

essary wires from the remote start switch.

4. Confirm unit is in “AUTO” mode. The LCD display should have “AUT” hilighted in the upper left corner.

5. Close (set to ON/“I”) the main circuit breaker.

6. Secure the generator by closing and locking all access doors.

7. The generator is now ready for remote starting.

SHUTTING DOWN THE GENERATOR

Check with other personnel using power supplied by the generator and let them know that the power is

going to be turned off. Make sure the power shutdown will not create any hazards by accidentally turning

off equipment that needs to be kept on (pumps, compressors, lights, etc.).

1. Remove all loads from the generator by opening (turn to OFF/“O”) all circuit breakers.

2. Let the engine run for approximately five minutes to allow it to cool down.

3. Push the “ENGINE STOP” button.

4. Move the control power switch to the CONTROL OFF/“O” position.

EZ-1 CONTROLLER INFORMATION DISPLAYS AND FUNCTION

The MAGNUM EZ-1 controller constantly monitors vital generator and engine functions for a number of

operation, alarm and fault conditions. When a fault condition occurs, the engine will shut down automati-

cally and the LCD display will show the fault that has caused the shut down. To resume operation, the fault

condition must be resolved. To reset the EZ-1 and resume operation, press the “FAULT RESET” button.

Operation, alarm and fault conditions and (displayed message) are described in the following table:

TROUBLESHOOTING AUTOMATIC SHUTDOWN CONDITIONS

LOW OIL PRESSURE SHUTDOWN

1. Check the level of the engine oil with the dipstick. The EZ-1 will shut the engine down when the oil

pressure is less than 20 psi. Add oil if required.

2. Visually inspect the engine for oil leaks.

3. If the oil level is good, restart the unit and verify the loss of oil pressure. Shut the engine down

immediately if the oil pressure value does not read 5 PSI within five (5) seconds.

4. Check the oil pressure sender on the engine block and the connecting wiring for damage. To

check for continuity between the sender and the EZ-1, remove the bolts at the top and center of the

control panel and open the panel like a door. Consult the DC wiring diagrams in this manual for the

proper path between the EZ-1 and the pressure sender.

5. If the oil level, pressure sender and wiring are good, the oil loss may be caused by engine failure.

Consult the engine OPERATION AND MAINTENANCE MANUAL for additional information on

excessive oil consumption.

HIGH COOLANT TEMPERATURE SHUTDOWN

1. Check the coolant level in the overflow jug.

2. Restart the engine and read the coolant temperature to verify High Coolant Temperature Shut-

down. Stop the engine immediately if the coolant temperature is 230°F or more.

3. Allow the engine to cool! Add coolant to the overflow jug if it is low and then check the level of

coolant in the radiator. To access the radiator cap, you must remove a small panel on top of the

generator housing directly above the radiator. Add coolant until it is 3/4” below the filler neck. Re

place the radiator cap and access panel.

4. Check the radiator shroud and ducting for blockage and remove any foreign matter.

5. Inspect coolant hoses, engine block and water pump for visible leaks.

6. Check the tension of the serpentine drive belt for the water pump.

7. Check the coolant temperature sender on the engine block and the connecting wiring for damage.

To check for continuity between the sender and the EZ-1, remove the bolts around the control panel

and slowly drop panel down. Consult the DC wiring diagrams in this manual for the proper path

between the EZ-1 and the pressure sender.

8. If the sender and wiring are good and no other problems are found, restart the engine. Observe the

coolant temperature and shut the engine down immediately if it starts to overheat.

9. Reduce the load on the generator and restart the engine. Observe the coolant temperature and

shut the engine down immediately if it starts to overheat. Consult the engine OPERATION AND

MAINTENANCE MANUAL for additional information on engine overheating.

TROUBLESHOOTING AUTOMATIC SHUTDOWN CONDITIONS, CONTINUED

OVERCRANK SHUTDOWN

1. Check the fuel level in tank.

2. Check for proper operation of the fuel pump.

3. If the engine will not start, consult the engine OPERATION AND MAINTENANCE MANUAL for

additional information on troubleshooting starting problems.

OVERSPEED OR UNDERSPEED SHUTDOWN

1. Disconnect all loads and restart the generator. Read the frequency (Hz) on the LCD display.

With no loads on the generator, the frequency should read 60.0 Hz.

2. If the frequency is above or below 60.0 Hz, the engine speed will have to be adjusted. See the

engine manual for throttle adjustments on mechanical governed units and see the electronic

governor manual for electronically controlled units.

TOWING THE TRAILER

1. Use the jack to raise or lower the trailer onto the hitch of the towing vehicle. Lock the hitch coupling

and attach the safety chains or cables to the vehicle. Release the jack locking pin and rotate the jack

into the travel position. Make sure the locking pin snaps into place.

2. Connect any trailer wiring to the tow vehicle. Check for proper operation of the stop and signal lights.

3. Make sure the doors are properly latched.

4. Check for proper inflation of the trailer tires.

5. Check the wheel lugs. Tighten or replace any that are loose or missing. If a tire has been removed for

axle service or replaced, tighten the lugs in the order shown to the following specifications:

A. Start all lug nuts by hand.

B. First pass tighten to 20-25 Ft-Lbs (27-33 Nm).

C. Second pass tighten to 50-60 Ft-Lbs (67-81 Nm).

D. Third pass tighten to 90-120 Ft-Lbs (122-162 Nm).

After the first road use, retorque the lug nuts in sequence.

6. Maximum recommended speed for highway towing is 45 m.p.h..

Recommended off-road towing speed is not to exceed 10 m.p.h. or less

depending on terrain.

TRAILER WHEEL BEARINGS

The generator is equipped with a grease zerk fitting to allow lubrication of the wheel bearings without

the need to disassemble the axle hub. To lubricate the axle bearings, remove the small rubber plug on

the grease cap, attach a standard grease gun fitting to the grease zerk fitting and pump grease into the

fitting until new grease is visible around the nozzle of the grease gun. Use only a high quality grease

made specifically for lubrication of wheel bearings. Wipe any excess grease from the hub with a clean

cloth and replace the rubber plug when finished. The minimum recommended lubrication is every 12

months or 12,000 miles; more frequent lubrication may be required under extremely dusty or damp

operating conditions.

ENGINE AND GENERATOR MAINTENANCE

Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely

and properly over a long period of time, periodic maintenance and occasional repairs are necessary.

NEVER perform even routine service (oil/filter changes, cleaning, etc.) unless all electrical components

are shut down. When servicing this equipment always follow the instructions listed below.

Before servicing this machine, make sure the control power switch is turned to off “O”, the circuit breakers

are open (off, “O”), the emergency stop switch is activated (pushed in), and the negative (-) terminal on

battery is disconnected. Attach a “DO NOT START” sign to the control panel. This will notify everyone that

the unit is being serviced and will reduce the chance of someone inadvertently trying to start the unit. If the

unit is connected to a remote start or transfer switch, make sure the remote switch is also off and tagged.

Never wash the unit with a high pressure hose or with any kind of power washer. Never wash the engine

block or fuel tank with a power washer or steam cleaner. Water may enter the cabinet and collect in the

generator windings or other electrical parts, causing damage. If the unit is stored outside, check for water

inside the cabinet and generator and dry the unit thoroughly before starting.

RELOADING THE TIME TO SERVICE REMINDER

DAILY MAINTENANCE CHECKS

Check the engine oil level daily before starting engine. DO NOT start the generator if the oil level is below

the ADD mark on the dipstick. The normal operating level for the engine oil is anywhere in the crosshatch

pattern between the FULL and ADD markings. Add oil to the engine only if the level is below the ADD mark

on the bottom of the crosshatch pattern. DO NOT OVERFILL the crankcase. Consult the engine OPERA-

TION AND MAINTENANCE MANUAL for the proper grade of oil, including special operating conditions such

as a change in season or climate.

Check the coolant level daily. The coolant is checked by visually inspecting the level in the coolant overflow

jug, located near the radiator. The normal operating level is anywhere between the FULL and ADD mark-

ings on the overflow jug, with the optimum level noted as “NORMAL RANGE”. Coolant may be added

directly to the overflow jug WHEN THE ENGINE IS STOPPED AND COMPLETELY COOL. Consult the

engine OPERATION AND MAINTENANCE MANUAL for coolant recommendations and proper mixture.

Check the condition of the air filter viewing the level of vacuum draw on the filter minder gauge. Replace

the air filter when the yellow center bar reaches the red section on the gauge (20 in. H20).

DERATING FOR ALTITUDE

All generator sets are subject to derating for altitude and temperature; this will reduce the available power

for operating to tools and accessories connected to the auxilliary outlets. Typical reductions in perfor-

mance are 2-4% for every 1000 ft. (305 meters) of elevation and 1% per 10º F (3-5º C) increase in ambient

air temperature over 72º F (22.2º C).
