DESCRIPTION AND IDENTIFICATION

A. FRONT PANEL

1. Starting Controls (1)- This unit is equipped for manual key start only. A three position key switch controls the engine starting.

Page 3

a. “OFF” - This switch position stops the engine and disconnects the power to the engine controls. It is intended to safely allow service and maintenance checks on the engine

b. “RUN” - This switch position engages the ignition circuitry on the engine and powers up the engine control panel and the engine sensors.

c. “START” - When the switch is rotated to this position the starter will engage, starting the engine. When the switch is released, it is spring loaded back to the run position.

2. Murphy Switchgauge (2) - The switchgauge will shut down the engine in case of low oil pressure or high water temperature. When starting the unit the button on the switchgauge must be depress as the key switch is rotated to the start position. It is released after the engine builds oil pressure.

3. DC Control Circuit Breaker (DCCB) (3)- The 15 amp DC Circuit Breaker protects the engine control and the engine ignition circuit against faults in wiring or control equipment.

lected, the switch may be locked to prevent it from accidentally being changed during operation. Three output voltage combinations are available with this selector switch:

4. Engine Instruments

a. Oil pressure monitor gauge (OPG) (4)- The oil pressure gauge is mounted on the front control panel and indicates the engine oil pressure. The gauge serves a dual function. In addition to displaying the oil pressure it also provides the shutdown signal to the switchgauge if the pressure should drop too low. The shutdown signal is factory preset at 15 psi (103 kPa/m sq).

b. Coolant temperature monitor gauge (CTG) (5)- The coolant temperature gauge indicates engine coolant temperature. The gauge serves a dual function. In addition to displaying the water temperature it also provides the shutdown signal to the switchgauge if the water temperature gets too high. The shutdown signal is preset to operate at 225 f (407 k)

c. Battery Voltage Meter (6)- This DC voltmeter monitors the VOLTAGE of the battery under static (at rest) conditions, and under cranking and charging conditions. The voltmeter indicates not only the condition of the charging system, but also indicates the battery reserve under cranking load in cold weather.

d. Running Time Meter (7)- This DC meter records the total hours the engine has run.

B. RECEPTACLES and CIRCUIT BREAKERS

1. 120 Volt 20 Amp Ground Fault Interupter Duplex. This duplex receptacle is protected by a 20 Amp circuit breaker mounted just above the duplex. With the “T” slot design both 15 and 20 amp 120 volt cords can be plugged in.

2. 120 Volt 20 Amp 3 wire twist lock, NEMA Spec L5-

20. This twistlock receptacle is also protected by a 20

Amp circuit breaker. This receptacle is wired in series with the GFCI receptacle which provides it with GFCI protection.

3. 240 Volt 20 Amp 3 wire twist lock, NEMA Spec L6-

20. This twistlock receptacle is protected by a two pole 240 volt circuit breaker.

4. 120/240 Volt 50 Amp 4 wire twistlock. This receptacle is rated for dual voltage, 120 or 240 volt use. It is a four wire receptacle, with a center grounding pin. Four wire drop cords plugged into this receptacle may be split into 120 volt receptacles at a distribution box. This receptacle is protected by a two pole 50 amp circuit breaker mounted just above it. THIS RECEPTACLE UTILIZES A SPECIAL HUBBELL PLUG. (HUBBELL PART NUMBER “CS 6365”.)

C. FULL POWER LOAD CONNECTIONS and BREAKERS

This Mobile Diesel Power System is equipped with both high voltage (480) and low voltage (208/240) main line breakers. The breakers are interlocked with a lockable bar to insure that only one breaker can be turned on at a time.

2. Description - The Basler model VR63-4C voltage regulator is a completely encapsulated unit. The regulator controls the DC exciter field voltage on brushless generators to regulate the output voltage. Regulation is provided by sensing the generator output voltage, converting it to a DC signal and comparing the signal to a reference voltage signal. An error signal is developed and used to control the DC field power in order to maintain a constant generator output.

3. Operation of Voltage Regulator - The voltage regulator has been installed in the Mobile Diesel Generator set and tested at the factory prior to shipment. No additional setup is required when changing from one voltage to another. The only adjustment required is to fine tune the exact voltage you want using the voltage adjustment rheostat located on the front panel. The adjustment range is 10% of the nominal voltage.

Some minor changes must be made for 50 cycle operation. Refer to 50 Hz operation later in this section for setup procedures.

a. During periods of operation at reduced speed use the field circuit breaker to remove the power from the regulator.

A full power output terminal block is provided. This terminal block is located below the main power breakers and is accessible through the access door located just below the main line breakers. If this access door is opened with the unit running a safety switch will disable the 12 volt system shutting the unit down. This door must remain closed and latched at all times during normal operations.

DANGER: PERSONAL INJURY

This unit will start as soon as the door is closed if the start switch is in the run position. Do not use the switch on this door to shutdown a unit to connect to the full load terminal block , this is a safety switch only.

E. VOLT/HERTZ VOLTAGE REGULATOR

The purpose of the voltage regulator is to maintain the voltage output of the Generator Set within a specified percentage of its rated output from no load to full load. The voltage regulator controls the voltage output of the main generator by regulating the amount of current delivered to the exciter field.

1. Location -Access to the voltage regulator assembly is gained by removing the control panel access door located through the left rear housing door.

b. If the exciter field voltage exceeds 95 VDC, the regulator senses over excitation and automatically removes the field current after a time delay. This time delay is inversely proportional to the magnitude of the detected over voltage condition. At approximately 140 VDC, the field voltage is removed instantaneously.

Upon detection of over excitation and the resulting field voltage shutdown, the regulator will not reset or return to an operational condition until the generator output voltage drops to less than 6 VAC for ten seconds (minimum). TO ACCOMPLISH THIS ON A MOBILE DIESEL GENERATOR SET THE FIELD CIRCUIT BREAKER MUST BE TURNED OFF FOR TEN SECONDS.

OPERATING THE UNIT

A. SELECTING THE CORRECT VOLTAGE

A variety of voltages are available from the three position selector switch. The three basic connection patterns are, Delta (120/240), Low or Parallel WYE (120/208), and High WYE (277/480). Single phase 120/240 is available with the switch in the 120/240 (Delta) position.

Before connecting this unit to a distribution panel or any other loads, be sure you have the selector switch set for the right voltage and locked. If you have any doubts as to

Page 5

the voltage in your area compare your incoming power or load name plates to the voltage table below.

1. 120/240 Three Phase* (Delta/Series configuration) This configuration will produce the following line-to-line and line-to-neutral voltage. In this selector switch position, all of the receptacles on the front panel are powered.

L1 - L2 - L3 240 Volts three phase L1 - L2 240 volts single phase L2 - L3 240 volts single phase L1 - L3 240 volts single phase L1 - N 120 Volts L2 - N 120 Volts L3 - N 208 volts

*This selector position is also used for single phase 120/240 output, using only the L1 and L2 leads. The L3 three phase output lead is the “wild” leg in the delta configuration and is used only for three phase loads.

B. STARTUP CHECKLIST

Before initial start up and each subsequent start complete the following checklist:

1. Check oil level, refill with proper grade oil.

2. Check coolant level, refill with proper mixture of coolant. See engine manual.

3. Check for loose bolts or hardware.

4. Check tire pressure. (35 psi)

5. Trailer level to within 15 degrees.

6. Battery securely fastened, connection clean and tight, and proper fluid level.

7. Fuel tank filled with the proper grade of diesel fuel.

8. Check the fan belt for tightness and excessive wear.

9. Check hoses and clamps for leakage.

10. Check the air cleaner indicator. Service only when indicated. Do not over-service.

11. Clean out dust cup on the air cleaner.

2. 120/208 Three Phase (Low/Parallel WYE configuration) This configuration will produce the following line-toline and line-to-neutral voltage. Use of this selector switch position allows utilization of the 120 volt receptacle only. The 240 volt receptacles cannot be used as the voltage at them will be 208 volts, the line to line voltage.

L1 - L2 - L3 208 Volts three phase L1 - L2 208 volts single phase L2 - L3 208 volts single phase L1 - L3 208 volts single phase

L1 - N 120 Volts L2 - N 120 Volts L3 - N 120 volts

3. 277/480 Three Phase (High/Series WYE configuration) This configuration will produce the following line-toline and line-to-neutral outputs. The 120 volt receptacles are the only panel receptacles powered in this voltage configuration. They are limited to 12 Amps total.

L1 - L2 - L3 480 Volts three phase L1 - L2 480 volts single phase L2 - L3 480 volts single phase L1 - L3 480 volts single phase L1 - N 277 Volts L2 - N 277 Volts L3 - N 277 volts

After you have selected the correct voltage for your application and locked the selector switch, do the same with the main line circuit breakers. Be sure to secure the lock bar in place. This will prevent the incorrect breaker from being turned on.

C. STARTING

CAUTION: EQUIPMENT DAMAGE

DO NOT ATTEMPT TO JUMP/BOOST START THIS UNIT. TURN THE DC BREAKER “OFF” AND RECHARGE THE BATTERY WITH A BATTERY CHARGER.

1. Select the desired voltage on the voltage selector switch and lock in place.

2. Turn off both main line circuit breakers.

3. Rotate the start switch to the “run” position. In this position without the engine running the safety latching relay will pop out.

4. While depressing the safety latching relay, rotate the start switch to the start position. This will engage the starter and the fuel solenoid allowing the engine to start.

5. As the engine starts release the start switch but keep the safety latching relay depressed. This will allow the spring loaded start switch to return to the run position.

6. After the engine has built up at least 15 psi of oil pressure, you can release the safety latching relay. If you release the safety latching relay before the engine has built oil pressure, the button will pop out, shutting the engine back down.

7. After the engine is running at proper speed, adjust the voltage to the desired level using the external voltage rheostat.

8. Turn on the proper main line breaker (either high or low voltage) and padlock the lock bar to prevent the incorrect breaker from being turned on.

9. To stop the unit simply turn the start switch to the off position. This will disconnect the 12 Volt DC to the fuel solenoid shutting the unit down.

Page 6

D. CONNECTING THE LOADS

50 CYCLE (HZ) OPERATION

There are two ways the loads may be connected to a Mobile Diesel Generator.

1. FRONT PANEL - A variety of receptacles have been provided for your convenience on the front panel. The 120 volt receptacles are powered when the voltage selector switch is in the 120/240 or 120/208 volt position. The 240 volt receptacles (although powered in both positions) are only usable in the 120/240 volt position. In the 120/208 volt position the 240 volt receptacles have only 208 volts at them.

2. FULL POWER LOAD CONNECTION TERMINAL BLOCK - For remote connections and connecting load distribution boxes, heavy duty terminal blocks have been provided. These terminal blocks are located behind the access door on the side of the unit, just below the main line circuit breakers. This access door has a safety switch installed on it and cannot be open while the engine is running. Opening this door with the engine running will cause the safety latching relay to trip, shutting the unit down. The neutral and ground are bonded together at this panel. For use with an isolated neutral, remove the jumper strap between the neutral connection block and the ground lug. This will isolate the neutral from the ground and allow you single point grounding at a distribution panel. When using these terminal blocks be sure to use wire rated large enough to carry your full load or the full rated load of the generator.

WARNING - EQUIPMENT DAMAGE

FAILURE TO PROPER TIGHTEN THESE TERMINAL LUGS CAN AND WILL CAUSE DAMAGE TO BOTH THE TERMINAL BLOCK AND THE GENERATOR. IF NOT PROPERLY TIGHTENED THESE LUGS CAN START TO ARC INTERNALLY CAUSING DAMAGE TO THE TERMINAL LUGS AND GENERATOR DAMAGE.

3. GROUNDING THE UNIT - To comply with current safety standards this generator set must be properly grounded. Ground the Mobile Diesel Generator set by driving an 8 ft. copper ground rod into the earth. Then connect a #4 AWG ground cable from the grounding lug on the generator to the ground rod.

With a couple of minor changes these Mobile Diesel Generators are capable of producing 50 Hz power. Two changes must be made.

A. The engine must be reduced to 1500 RPM governed speed. Consult your local John Deere Service Center for the proper procedure for reducing the engine speed and setting up the governor to operate at 1500 RPM.

B. The automatic volt/hertz regulator must also be reset to operate at 50 HZ instead of the standard 60 HZ. This is done by cutting the two leads marked HZ that come out of the regulator. This will change the regulator for 60 HZ operation to 50 HZ operation. If it should become necessary to change it back to 60 HZ, you would need to splice the leads together again.

MAINTENANCE

The ultimate aim of a preventive maintenance program is to maintain the equipment in optimum condition, either in service or ready for service, for the maximum amount of time during the useful life of the equipment. The detection of faults before they develop into major sources of difficulty will decrease the incidence of repair. To this end, a regular schedule of cleaning and inspection will go far toward assuring trouble-free operation. Personnel responsible for maintenance should set up a schedule for inspection, and cleaning at intervals calculated to keep the equipment in good condition. In making up a schedule, keep the following in mind:

A. New equipment must be carefully monitored until extended operation has demonstrated that it is performing satisfactorily.

B. Old equipment requires more frequent inspection (and possibly servicing) than similar equipment that has seen less service.

C. Time spent in cleaning, inspecting and correcting minor defects before they become major troubles means time saved in overhaul and repair.

F. UNIT STORAGE

Certain precautions must be taken if a Mobile Diesel Generator set is to be stored for a long period of time. The unit must be stored in a dry location to prevent the generator winding from drawing moisture. The unit should also be thoroughly cleaned prior to storage.

For engine storage procedures consult your local John Deere engine dealer. They have certain procedures that must be followed in order to prevent engine damage, i.e. cylinder rust and injector deterioration.
