DESCRIPTION OF EQUIPMENT

The engine/generator assembly consists of adiesel engine combined with an electrical genera-tor. This assembly is firmly bolted together to forman integral unit and does not require anythingother than routine maintenance.

The engine is equipped with a 12-volt starter (24-volt starter optional) and can be wired for remotestarting capability at the control panel.

A dry-element air cleaner is standard equipment toensure a clean air supply, and a remote fuel/waterseparator is included for additional fuel systemprotection.

A governor on the engine provides a stableoperating speed under varying load conditions,and the generator is equipped with a solid-statevoltage regulator to stabilize the output voltageunder these same conditions. Figures andschematics of both the governor and regulator areprovided in the ENGINE and GENERATOROPERATOR’S MANUALS.

An automatic shutdown system is incorporated inthe generator set to sense low oil pressure and/orhigh coolant temperature, and in either case theengine/generator assembly will automaticallycease operation.

A diesel fuel tank is incorporated within the baseof the unit to ensure an uninterrupted operatingcycle under full load. The engine/generatorassembly is mounted to the base using highdurometer vibration isolators.

The enclosure for the generator set is constructedfrom 12 or 14-gauge sheet metal to ensuremaximum rigidity, and is bolted together to alloweasy access to major components if necessary.Four lockable, hinged access doors are providedfor routine operation and maintenance.

The enclosure on the Super Quiet Generator isspecifically designed for a high degree of soundattenuation. This allows the generator set to beoperated in noise-sensitive environments. Theinterior of the enclosure is coated with sound-dampening polymer foam that is highly effective innoise suppression and is impervious to water, fuel,and oil.

A high ambient temperature radiator and a criticalgrade exhaust silencer are contained within the

OPERATING INSTRUCTIONS

STARTING THE ENGINE/GENERATOR SET

Once setup procedures are completed, thegenerator set is ready to be started. Start theunit according to the following steps:

• Make sure the GENERATOR VOLTAGESELECTOR SWITCH has been set to theproper range.This switch should be locatedabove the 3-phase distribution panel.(DISREGARD IF THE UNIT DOESN’T HAVEA SELECTOR SWITCH. THIS UNIT ISPRESET FOR ONE VOLTAGE. SEE NAMETAG.)

NEVER CHANGE THE POSITION OF THEVOLTAGE SELECTOR SWITCH WHILE THEGENERATOR IS RUNNING! THIS WILLRESULT IN IMMEDIATE DAMAGE TO THESWITCH, THE GENERATOR, OR THECONNECTED EQUIPMENT. IT MAY RESULTIN SERIOUS INJURY TO THE OPERATINGPERSONNEL.

• Place the toggle switch in "ON" position thenpress the MANUAL ("MAN") BUTTON on theCascade Controller. The unit will start anautomatic timing sequence . After the timingsequence the engine will attempt to start. Makesure all debris and obstructions have beencleared from moving parts and electricalterminals. The generator will only make 3attempts at starting before it must be reset withthe switch.

NEVER ATTEMPT TO START THE GENERA-TOR SET WITH ANY OF THE CIRCUIT BREAK-ERS "ON". THESE BREAKERS ARE LOCATEDON THE DISTRIBUTION PANEL. STARTINGWITH THE BREAKERS "ON" CAN CAUSEDAMAGE TO THE GENERATOR.

• Now that the generator set is running, allow fiveminutes for warm-up time.

• Listen for any unusual sounds or excessvibrations that could signal problems andrequire immediate shutdown of the unit. Shouldunusual sounds be detected, shut the unitdown, and contact TEREX Service.

• Once the engine has been started and runningsmoothly, the following gauges should bemonitored. All gauges are located on the controlpanel.

• Oil Pressure Gauge - This gauge should read30 psi or higher.

• Coolant Temperature Gauge -This gaugeshould read between 170-200 degrees F.

• Voltmeter - This gauge should read at least 12volts DC to indicate the diesel engine’salternator is charging properly.

• AC Voltmeter - This gauge should reflect theproper voltage selected for this operation.

• AC Ammeter - The reading on this gaugeshould be zero since the main breaker is in the“OFF” position. Once a load is applied to thegenerator, the ammeter will produce anappropriate reading.

VOLTAGE SELECTOR SWITCHOPERATION

The voltage selector switch will have three posi-tions, and each position gives a different output tothe three-phase distribution lugs (designated as“L1”, “L2”, “L3”, and “N”) located on the distri-bution panel.

In the three-phase “480/277” position, the follow-ing will be the normal output voltages:

• Line - to - Line (“L1” to “L2”, “L2” to “L3”,“L1” to “L3”) 480 VAC/3P.

• Line - to - Neutral (“L1”, “L2” or “L3” to “N”)277 VAC/1P.

NOTICE: This three-phase wiring configurationis referred to as “Hi Wye”.

In the three-phase “208/120” position, the follow-ing will be the normal output voltages:

• Line - to - Line (“L1” to “L2” and “L2” to“L3”; “L1” to “L3”) 240 VAC/3P.

• Line - to - Neutral (“L1”, “L2”, or “L3” to“N”) 139 VAC/1P.

NOTICE: The above voltages can be “dialeddown”, or adjusted lower, by using the voltageadjustment potientiometer located on the gen-erator main control panel.

NOTICE: This three-phase wiring configurationis referred to as “Lo Wye”.

The three position selector switch has HI WYE480 V 3ph., LOW WYE 240 V 3ph. and 240Vsingle phase that is Zig Zag. The following is theoutput voltages on the zigzag position.

INSTALLATION AND ANY WORK PERFORMEDON THIS UNIT SHOULD BE DONE ONLY BY AQUALIFIED ELECTRICIAN.

DO NOT REMOVE OR COVER ORIGINALSAFETY AND OPERATION DECALS. REPLACEANY DAMAGED DECALS BEFORE USING THISEQUIPMENT!

LED STATUS LIGHTS

Eleven LEDs separated into two banks (see “Fig.1”) are provided on the faceplate. The LEDs Bank1 includes 6 LEDs and Bank 2 includes 5. InSetup mode, these banks form a binary code toindicate either the controller setup configuration orerror status, which is indicated by the last 8 (red)LEDs. Refer to Tables 1, 2, 3 and 4 ( See "Cas-cade Controller Installation and Operations

Manual" supplied with unit) for configuration andstatus listings.

One LED is located next to the “AUTO” button toindicate that the controller is waiting for the remotestart input to become active. The LED status lightsare (from top to bottom) see “Fig. 1”:

Engine running - If the green LED is on, then theunit is receiving a speed signal, indicating that theengine is above the crank cut speed.

ECU status - If the green LED is on solid, itindicates that in a J1939 application the ECU andthe unit are communicating properly. If the LED isblinking slowly the ECU is broadcasting a mes-sage. If the LED is blinking fast, the ECU is NOTcommunicating properly.

Remote Start/ Crank Rest - If the green LED ison, then the remote start input is active and if thesystem is in "AUTO" mode, it will try to start. If theLED is blinking, the crank cycle has ended and isnow in crank rest cycle.

Low oil pressure - If the red LED is on, thecontroller has caused the engine to shutdown andlockout. If the LED is blinking, the engine ECU hastransmitted a SPN for an oil pressure relatedcondition.

High Engine Temperature - If the red LED is on,the controller has caused the engine to shutdownand lockout. If the LED is blinking, the engine ECUhas transmitted a SPN for an engine temperaturerelated condition.

Overspeed - If the red LED is on, the controllerhas caused the engine to shutdown and lock outdue to engine speed exceeding the setpoint.

Underspeed - If the red LED is on, the controllerhas caused the engine to shutdown and lock outdue to engine speed falling below the minimumneeded for proper operation.

Overcrank - If the red LED is on, the controllerhas exceeded the set number of start attempts

The potentiometer is set at the factory. However, ifthe voltage reading on the voltmeter is not asdesired use the following procedure to make thenecessary adjustments. With the unit running,under no load, observe the AC voltmeter. Locatethe voltage adjustment knob on the control panel.The decal above the knob indicates the directionto turn the knob to increase or decrease thevoltage. Turning the knob to the right increasesthe voltage while turning the knob to the leftdecreases the voltage. Slowly turn the adjustmentknob in the desired direction, while observing theAC voltage meter, stop when the desired voltageis obtained. The unit is now ready to load. If thedesired voltage cannot be reached contact theTEREX Service Department at 1-800-433-3026.

In the event of a fault that causes the engine toshutdown, the cause of the event will be indicatedon one of the 11 status lights on the right handside of the controller (See Fig. 1). When the causeof shutdown is corrected, the controller canresume normal operation.

without receiving a valid speed signal indicatingthat engine speed is above crank disconnect. Thiscauses the engine to shutdown and lockout.

Charge Fail - If the red LED is on, it indicates thatthe battery charging alternator is not charging thecranking batteries, or that the battery charger failoutput is on.

Aux 1 - If the red LED is on, it indicates that thiscustom-configured input is active. On an ECU(ECM) equipped engine, if this LED is blinkingslowly, it indicates that one or more engineparameters are near exceeding enginemanufacturer’s setpoints. If the LED is blinkingfast, it indicates that one or more engine param-eters have exceeded setpoints, the ECU hasissued a fault - and most likely the engine hasshut down.

Aux 2 - If the red LED is on, it indicates that thiscustom-configured input is active.

Overspeed & Underspeed - If these two LED’sare both blinking, the controller has lost its speedsignal.

CARE AND SERVICING AIR FILTERS

A common belief in air filtration is that new cleanfilters are the best. In reality, a filter is the leastefficient it will ever be when it is first installed.Filter paper is specially designed paper that iswoven with a series of small openings that allowsair to pass through it and dust to be stopped. Assmall particles of dust are trapped in the paper,the holes become smaller and the efficiencyincreases.

Operating Instructions and Parts Manual

June 2006REV A

MAINTENANCE (Cont.)Enginaire filtration systems using stagedprecleaners, keep large particles of dust from theair stream, which would bridge across the elementand cause premature filter failure.The most common cause of engine failure due todust ingestion is over servicing.

DO NOT USE VISUAL INSPECTION TO DETER-MINE FILTER FAILURE.

Use a dust load indicator (vacuum gauge) todetermine when the filter should be changed.These are available in many configurations butshould trigger when 10-15 inches of water columnover the clean element is reached. When youremove a filter from the canister, the seal isbroken and loose particles of dust can fall into theoutlet and be drawn into the engine the next time itstarts. Leave the inner (safety) element installed,as this will protect against loose debris enteringthe engine.

General cleaning of cartridges should be accom-plished by either a light brushing or mild airpressure application.

NEVER DIRECT A HIGH-PRESSURE AIRSTREAM DIRECTLY INTO A FILTER PACK ASIT MAY RESULT IN MEDIA BREAKDOWN.NEVER TAP A FILTER TO REMOVE DIRT ASTHIS COULD DAMAGE THE SEALING SUR-FACES.

Carefully remove any loose dust from the canister-using a vacuum and then wipe with a damp cloth.

NEVER BLOW AIR INTO THE CANISTER AS ITMAY FORCE DIRT INTO THE ENGINE.

Make sure the sealing areas of the canister andthe element are clean and free of defect beforeinstalling the element. The safety element shouldbe changed sparingly (every three or four filterchanges) and extreme care should be taken to notallow dirt to enter the engine when the safety

element is removed.

NEVER WASH THE CANISTER WITH HIGHPRESSURE WATER AS IT COULD DAMAGEOR BREAK THE PRECLEANER ROTOR.

5 COMPONENTS THAT CAUSEVOLTAGE RELATED PROBLEMS

POTENTIOMETER

Connects to voltage regulator. Bypass potentiom-eter by unplugging from voltage regulator andinstalling jumper on 2 male spades on regulator.

VOLTAGE REGULATOR

(Located inside the upper control panel behind thegauges.)

Measure DC voltage at F1 & F2. Normal voltage is10 to 12 V DC. Remove 2 wires marked (F1,X)(F2, X X) from voltage regulator. Connect wiremarked F1 to positive and F2 to negative of a 12volt battery. Start unit and measure voltage. If unitproduces close to maximum output, replaceAutomatic Voltage Regulator.

VOLTAGE SELECTOR SWITCH

The correct way to test is to disconnect fromgenerator and hard wire the generator into oneconfiguration. This will eliminate the switch fromthe circuit and verify that the generator is function-ing properly. All contacts should be checkedfollowing the proper schematic with the switchdisconnected from the generator set. Actual loadscan cause failures in contacts that cannot beduplicated using a meter.

OVERCURRENT RELAY

This device causes the 3-phase breaker to tripthat supplies AC power to the distribution lugs ifuneven or excessive current is measured at thedistribution lugs. It is also connected to the 3-phase door switch and will automatically trip the 3-phase breaker when the door is open and pre-vents the breaker from being reset while it is open.

GENERATOR

Test resistance of field, stator and exciter wind-ings. Contact TEREX for procedures or repairfacility recommended by generator manufacturer.

PROCEDURE FOR TESTINGGENERATOR WITH NO OUTPUT

THIS EQUIPMENT USES HIGH VOLTAGECIRCUITS CAPABLE OF CAUSING SERIOUSINJURY OR DEATH! EXCERCISE EXTREMECAUTION AROUND ANY ELECTRICALCOMPONENT WHEN OPERATING THIS UNIT.

IT IS ESSENTIAL THAT ALL TEST INSTRU-MENTS ARE REGULARLY CHECKED FORSAFETY, AND ANY CONNECTION LEADS,PROBES, OR CLIPS, ARE CHECKED TOENSURE THAT THEY ARE SUITABLE FORTHE VOLTAGE LEVELS BEING TESTED.

NEVER ATTEMPT TO TEST A "LIVE" GENERA-TOR UNLESS THERE IS ANOTHER COMPE-TENT PERSON PRESENT WHO CAN SWITCHOFF THE POWER SUPPLY OR SHUT DOWNTHE ENGINE IN AN EMERGENCY.

NEVER EXPOSE "LIVE" CONNECTIONS UN-LESS YOU HAVE CREATED A SAFE WORKINGAREA AROUND YOU. MAKE SURE YOU HAVEMADE ALL OTHER PERSONS IN THE IMMEDI-ATE AREA FULLY AWARE OF WHAT YOUARE DOING.

• When a new generator is not producing voltage,the testing or wiring personnel should first verifythat the unit is wired correctly! The stack switchand generator leads should all be checked aswell as the breaker and sensing leads. If theunit was not wired correctly and you flashed thegenerator, you could burn up the unit. (Do notforget to check the sensing leads!).

• After performing the initial checks above,remove the field wires from the voltageregulator (F1 or X is positive and F2 or XX isnegative). Connect the battery + to the F1 or Xwire and battery - to the F2 or XX wire. Start theengine and check for the rated voltage.Hooking this up incorrectly will reversepolarity and could damage the voltageregulator and /or generator end. This checkshould correct any voltage problems. If yourvoltage does not come up to the rated voltage,this indicates an internal problem with thegenerator end. The output should be close toproper voltage. Also, if the unit comes up tovoltage, check for even reading across the linesif they are not this would mean you probablyhave a problem with the wiring of the switch orgenerator. If the generator voltage readscorrectly you know there is not a problem withthe generator end. Your problem is more thanlikely with the voltage regulator. In this case,you should contact the TEREX servicedepartment.

• If the voltage is uneven between the legs whenyou apply 12 volts to the field wires you need torecheck your wiring connections. (If you cannot find the problem hard wire thegenerator!) After you have the field wireconnected start the unit again and check youroutput voltage. It may still be necessary to flashthe fields to restore residual voltage. This needsto be done with the unit off and the field wiresremoved. (Do not flash the regulator, flashthe field wires)

• As with any electrical device use extremecaution when working around a runninggenerator it could cost you your life. Observeproper polarity when working with the regulatorso you don’t break something that is not brokento begin with, and if you are ever in doubt, ask.

• Make sure generator is turned off and e-stop isengaged before opening control panel.

• Locate the two wires going to the speedcontroller mounted on the inside of the controlpan marked MPU + and MPU -.

• Both wires are isolated in their own shieldedcable.

• Once the wires are loose, pull them through theback of the control box until they are completelyfree from all ty-wraps and wire harnesses.

• Unscrew and remove the old sensor.

• Align the flywheel tooth to the center of thesensor hole.

• Install new sensor until it bottoms out onflywheel tooth and then back it off ¼ turn.

• Make sure generator is turned off and e-stop isengaged before opening control panel.

• Locate the two wires going to the back of thepotentiometer. Both wires will be white with ared stripe.

• Both wires have been spliced into harnesswires and should be cut so that the splice istaken out. It is better to have as few splices aspossible and you will be replacing the spliceyou cut out.

• Once the wires are loose, go to the front of thecontrol panel and loosen the lock nut holdingthe potentiometer.

• Put the new potentiometer in its place andretighten lock nut.

• Reattach new wires to the same wires and inthe same configuration as the ones that werecut loose in step 3.

• After completing the installation of the newpotentiometer go back and check allconnections to make sure everything is tightand that no connections are loose, this includesall other wiring on the back of the control paneland on the inside of the control box.

• You should now be able to restart the generatorand check for proper operation.
