Description
USAF TO 35C2-3-518-1 USA TM 9-5115-484-14 DRS RADIAN CTM 01646.1R0253/1R0254
Oil flows into the cylinder head via a hollow locating dowel in the top deck of the cylinder block. Oil travels to the camshaft bearing journals and the three center rocker arm shaft supports through drilled passages in the cylinder head. The supports supply oil to each rocker shaft. Oil flows to the bushings of the injector rocker arm through holes in the rocker arm shaft. This same oil lubricates the valve and the rollers. Oil flows through drilled passages in the rocker arms. This oil lubricates the roller, the valve bridge and the contact surfaces of the actuator of the unit injector. The remaining valve system components are lubricated by splash oil. When all the components have been lubricated, the excess oil returns to the engine oil pan. 3.9.2

LUBRICANT SPECIFICATIONS
3.9.3.1
API AUTHORIZED OILS
Caterpillar, Inc., the manufacturer of the DPDGS 3456 EPG Engine, recognizes The Engine Oil Licensing and Certification System for engine oils by the American Petroleum Institute. For detailed information about this system, see the thirteenth edition of the API publication No. 1509. API authorizes engine oils that bear the API symbol. 3.9.3.2
ENGINE OIL: CATERPILLAR DIESEL ENGINE OIL
Caterpillar Oils have been developed and tested in order to provide the full performance and service life that has been designed and built into Caterpillar Engines. Caterpillar Engine Oil is used to fill the 3456 EPG Engine at the factory. These oils are available by Caterpillar dealers worldwide for continued use when the engine oil is changed. Due to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations: •
Caterpillar Diesel Engine Oil (10W3O)
•
Caterpillar Diesel Engine Oil (15W40)
Caterpillar multi-grade Diesel Engine Oil is formulated with the correct amounts of detergents, dispersants, and alkalinity in order to provide superior performance in Caterpillar Diesel Engines. Caterpillar multi-grade Diesel Engine Oil is available in two grades of viscosity (10W30 and 15W40). To choose the correct grade for the ambient temperature, see Table 3.9.3.4-1. Multi-grade oils provide the correct viscosity for a broad range of operating temperatures. Multi-grade oils are effective in maintaining the following conditions: •
Proper engine lubrication
•
Low oil consumption
•
Low levels of piston deposits
3.9.3.3
ENGINE OILS: COMMERCIAL OILS
The performance of commercial diesel engine oils is based on classifications that were created by the American Petroleum Institute (API). These API classifications are developed in order to provide commercial lubricants for a broad range of diesel engines that operate in various conditions.
3-128
USAF TO 35C2-3-518-1 USA TM 9-5115-484-14 DRS RADIAN CTM 01646.1R0253/1R0254
If Caterpillar multigrade Diesel Engine Oil is not used, only use commercial oils that meet the following classifications: •
EMA LRG-1 multigrade oil is Preferred Oil
•
API CH-4 multigrade oil is Preferred Oil
•
API CG-4 multigrade oil is Preferred Oil
•
API CF-4 multigrade oil is Acceptable Oil
The following explanations of these API classifications can be used to make the proper choice when commercial oil is chosen: •
CH-4 is the newest API classification for heavy-duty diesel engine oil. CH-4 oils can be used in Caterpillar diesel engines that are recommended to use CF-4 oils.
•
CG-4 is a new API classification for heavy-duty diesel engine oil. CG-4 oils can be used in Caterpillar diesel engines that are recommended to use CF-4 oils.
In comparison to CF-4 oils, CG-4 oils provide improvements in the following performance: •
Cleanliness of the crankcase
•
Cleanliness of the pistons
•
Soot Dispersion
•
Viscosity Control
CH-4 oils were developed primarily for diesel engines that use a .05 percent level of fuel sulfur. However, CG-4 oils can be used with higher sulfur fuels. CH-4 oils were the first oils that passed the industry standard tests for foam control and viscosity shear loss. CG-4 oils must also pass tests that were recently developed for corrosion and wear. These oils service a wide variety of modern diesel engines. CF-4 oils provide more stable oil control and reduced piston deposits in comparison to the obsolete API CE oils. CF-4 oils provide improved soot dispersion in comparison to API CF and obsolete CD oils. The API CF-4 classification was developed with a 0.40 percent sulfur diesel fuel. This represents the type of diesel fuels that are commonly available worldwide. Some commercial oils that meet the API CG-4 and CF-4 classifications may require reduced oil change intervals. To determine the oil change interval, closely monitor the condition of the oil and perform a wear metal analysis. Caterpillar’s S.O.S. oil analysis program is the preferred method. NOTE:
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
NOTE:
Do not use CE-4 or lower grade oils.

LUBRICANT VISCOSITY RECOMMENDATIONS
The minimum ambient temperature during cold engine start-up; and the maximum ambient temperature during engine operation determine the proper SAE viscosity grade of oil. Table 3.9.3.4-1 presents the oil viscosities required for starting in minimum and maximum temperatures. Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at engine start-up. TABLE 3.9.3.4-1

ENGINE/ALTERNATOR SYSTEM
The Engine/Alternator System is comprised on the Caterpillar 3456 EPG engine and the Caterpillar SR4B Alternator mounted on a common skid. 3.10.1
CATERPILLAR 3456 EPG ENGINE
The MEP-PU-810 A/B Power Unit uses two Caterpillar 3456 EPG Engines. The two 3456 EPG engines are electronically controlled, mechanically actuated, unit injector diesel engines. The 3456 EPG Engine is an in-line six-cylinder engine with a bore of 5.5 inch (140 mm) and with a stroke of 6.7 inch (171 mm). The 3456 EPG Engine has a total displacement of 964.18 Cubic Inches (15.8 L). The engine is turbocharged and cooled with air-to-air after cooling with electronic unit injection (EUI). Figure 3.10.1-1 through Figure 3.10.1-5 illustrates the 3456 EPG Engine through the series of Right Side, Left Side, Top, Rear and Front Views.

The electronic control system was designed to provide electronic governing, automatic fuel ratio control, torque rise shaping, injection timing control, and system diagnostics. The Electronic Unit Injector system eliminates many of the mechanical components of an in-line pump system. This system also provides increased control of the timing and of the fuel air ratio. The timing advance is achieved by the precise control of the injector timing. Adjusting the duration of the injection controls the engine rpm. A special pulse wheel provides information to the electronic control module for the detection of the cylinder piston positions and of the engine rpm. The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition by the fault or alarm lights on the GSC+. The GSC+ will display some diagnostic codes and the Caterpillar ET tool can be used to read the numerical code of the faulty component or its condition. Intermittent faults are logged and the information is stored in the memory of the ECM.

3.10.2
STARTING THE ENGINE
The Electronic Control Module (ECM) will automatically provide the correct amount of fuel that is necessary to start the engine. The ECM controls the starting-aid operation automatically. At engine coolant temperatures below 32°F (0°C), the ECM will control ether injection. The Electronic Modular Control Panel (EMCP+), controls the crank cycles and duration of the starter motor. If the engine fails to start, the EMCP+ will cycle cranking to allow the starter motor to be cooled for the programmed cycle time. WARNING DO NOT MANUALLY SPRAY ETHER INTO THIS ENGINE. EXCESSIVE ETHER (STARTING FLUID) CAN CAUSE PISTON AND RING DAMAGE. NOTE: 3.10.3
Use ether for cold weather starting purposes only. COLD MODE OPERATION
The engine control system performs a cold start strategy for the correct warm-up time after a cold engine start. The temperature for a cold engine start is less than 64°F (18°C). This cold start strategy is called cold mode. After being activated, this cold mode will remain active until the coolant temperature rises above 64°F (18°C) or until the engine has been running for 12 minutes. Cold mode will also vary the fuel injection amount, the timing for the maximum start-up, and the timing for the control of white smoke. The time that is necessary for the engine to achieve the normal mode of operation is usually less than the time that is required for a walk-around inspection of the engine. 3.10.4
MEP-PU-810 SPECIFIED PARAMETERS
The engine is capable of being programmed for several customer-specified parameters. Refer to Annex B, C, E, and F for each of the DPGDS specified parameters.

ALTERNATOR
3.10.5.1
SR4B ALTERNATOR
Figure 3.10.5.1-1 illustrates the DPGDS SR4B Alternator. The SR4B is a three-phase, alternating current, brush less type generator. It is a four-pole design. The stationary main armature bolts to the engine flywheel housing. A flexible plate type coupling connects the rotor shaft to the engine flywheel. The rotating main field is keyed directly to the rotor shaft. The generator is self-ventilated with air entry through screened openings at the rear of the generator and air discharge through screened openings at the drive-coupling end. The fan attaches to the rotor shaft. A bearing supports the exciter end of the rotor shaft.
FIGURE 3.10.5.1-1 3.10.5.2
DPGDS SR4B ALTERNATOR
GENERATOR THEORY OF OPERATIONS
The DPGDS SR4B Alternator is a Permanent Magnet Pilot Excited (PMPE) type. Figure 3.10.5.1-1 illustrates the components of the SR4B Alternator. An engine supplies the power to turn the Rotor Shaft. The Exciter Armature (Rotor) and Main Field (Rotor) attach to the Rotor Shaft. As the Rotor Shaft turns, the Exciter Field (Stator) and Rectifiers generate DC current. This DC current is supplied to the Main Field (Rotor) and creates a magnetic field around the poles of the Main Field (Rotor). The Automatic Voltage Regulator (AVR) controls current. As the Main Field (Rotor) turns with the Rotor Shaft, the magnetic field also rotates and induces an AC voltage into the Main Armature (Stator). The Main Armature (Stator) is a coil with many turns of wire and the current that flows through it also flows to the load. The Exciter Field (Stator) supplies DC current to the Main Field (Rotor). Load (terminal) voltage is controlled, by varying the current to the Exciter Armature (Rotor).

3.10.5.3
PERMANENT MAGNET PILOT EXCITER (PMPE)
Figure 3.10.5.3-1 illustrates the PMPE Generator Wiring Diagram. Permanent magnet pilot excited generators receive power for the voltage regulator from a pilot exciter, rather than from the main armature as in self-excited generators. The pilot exciter consists of permanent magnet (PM) and Pilot exciter armature (L5). The pilot exciter operates independently from the generator output voltage. Constant excitation during large load application is possible, because the irregularities that occur in generator output voltage (caused by load conditions) are not fed back into the exciter. The independent operation also allows the generator to supply and sustain excessive currents for short periods of time. When the engine starts turning the rotating field assembly (RFA), a permanent magnet (PM) induces an AC voltage in the pilot exciter armature (L5). The pilot exciter armature has three coils of wire and generates three-phase AC. The resulting AC flows through wires T1 PMG, T2 PMG and T3 PMG to the voltage regulator. Within the voltage regulator the three-phase AC is rectified to DC and a controlled amount is fed to exciter field (L1) through terminals Fl and F2.

DC now flows to the exciter field (L1) and a magnetic field is created, in which exciter armature (L2) is rotating. The exciter field (L1) and exciter armature (L2) generates three-phase AC. The AC is then rectified to DC by three-phase full wave bridge rectifier circuit (diodes CR1-CR6). The DC output from the bridge rectifier is carried to the main field (L3) by conductors, which are routed through a passage in the generator shaft. Current through the main field (L3) creates the magnetic field of the generator. As the main field (L3) rotates, it induces a three-phase AC voltage in the main armature (L4), which is sent to terminals TO, T1, T2 and T3, which are connections for the load. To keep the output voltage constant with changing loads, it is necessary to control the exciter current. This control is the function of the voltage regulator. The voltage regulator senses the generator output voltage at wires 20 GEN, 22 GEN and 24 GEN. The voltage regulator uses the current generated from the permanent magnet (PM) and pilot exciter armature (L5) at wires T1 PMG, T2 PMG and T3 PMG. This current is then controlled by the voltage regulator and sent to the exciter through wires Fl and F2. Permanent magnets (PM) supply the initial magnetism required at start-up. Flashing the field is not required for start-up of the generator. 3.10.5.4
GENERATOR COMPONENTS
The SR4B generator design includes: •
Power for the exciter field is provided by a Permanent Magnet Pilot Excited (PMPE) method of excitation.
•
Bearing location (inboard). The size and vibration characteristics of the engine and generator determine whether the bearing is located inboard or outboard of the exciter. On the DPGDS, the bearing is inboard of the exciter.
•
On PMPE generators, the pilot exciter is either inboard or outboard of the exciter.
On the
DPGDS, the pilot exciter is outboard of the exciter. •
The Rotating Field Assembly (RFA) components attach to rotor shaft, which is supported by the engine flywheel and bearing.
•
The Generator main field rotor is part of the rotating field assembly and rotates with the shaft.
Figure 3.10.5.4-1 illustrates the heat sink on the end of the Rotating Field Assembly (RFA). The 6-diode rectifier block contains six diodes (CR1-CR6) of the bridge rectifier circuit and Varistor (CR7). The heat sink also contains an additional varistor (CR8). The two varistors are used to protect the diodes by suppressing any abnormal transient peak voltages in the generator circuit. The varistor is a voltage dependant resistor that has a high resistance at low voltage and a low resistance at high voltage. This allows current to pass through the varistor to ground when voltage spikes are present. The terminals, marked AC, connect to the wires from the exciter armature (L2). The terminals marked + and – connect to the main field (L3).

COMBUSTION AIR FLOW
Figure 3.11.1.1-1 illustrates the Combustion Air Flow within the Air Intake and Exhaust System. The turbocharger pulls combustion air through the Air Cleaner Assembly into the compressor side of the turbocharger. The combustion air is compressed which heats it to about 300°F before being pushed to the aftercooler (ATAAC). The combustion air flows through the aftercooler core and the temperature of the compressed combustion air is then reduced to around 110°F before entering the Air Inlet Manifold.

EXHAUST GAS FLOW
Figure 3.11.1.2-1 illustrates the Exhaust Gas Flow. Exhaust gases & noise are dispersed through top of the Power Unit (PU). Exhaust gases flow through the exhaust manifold to the turbine side of the turbocharger to drive the turbine wheel. Air is pulled into the system by the compressor wheel, which is connected to the turbine wheel by means of a common shaft. After leaving the turbine, exhausted gases pass out through the Muffler Assembly.

POWER UNIT INTERNAL COOLING AIR FLOW
Figure 3.11.1.3-1 illustrates the Power Unit Internal Cooling Air Flow. Cooling air is drawn into the interior of the PU from two areas. One entry point is the rear of the trailer at the alternator end. Air removes ambient heat from the Alternator and Engine and is drawn by hydraulic driven cooling fans, and pushed through the top of the Power Unit above the radiator. The other entry point is below the radiator assembly, where hydraulic driven fans push cool air up through for the Radiator and ATAAC then through the top of the Power Unit.

AIR-TO-AIR AFTER COOLER (ATAAC)
Figure 3.11.2.1-1 illustrates the Air-to-Air After Cooler. The ATAAC is separate from the coolant radiator by means of a sheet of metal that forms two separate compartments within Radiator/Air-to-Air After Cooler Assembly. Contained within ATAAC compartment is the Fuel Cooler. The purpose of the ATAAC is to cool the compressed combustion air. This makes the air denser so more air will be packed into each cylinder during the engine intake cycle thereby increasing engine efficiency.

Figure 3.11.2.3-1 illustrates the Turbocharger. The Turbocharger is situated next to the engine cylinder head assembly above the Exhaust Manifold. The purpose of the turbocharger is to increase horsepower output by pumping pressurized combustion air into the engine, allowing fuel to be burned more efficiently.
FIGURE 3.11.2.3-1
TURBOCHARGER
Exhaust gases flow through the exhaust manifold to the turbine side of the turbocharger to drive the turbine wheel. Air is pulled into the system by the compressor wheel, which is connected to the turbine wheel by means of a common shaft. After leaving the turbine, exhausted gases pass out through the Muffler Assembly. The air is compressed and heated to about 300°F (150°C) before the air is forced though the ATAAC and the temperature of the compressed air is lowered to about 110°F (43°C). The combustion efficiency increases because of the cooler inlet manifold air. This helps to provide lowered fuel consumption and increased horsepower output. The ATAAC is a separate cooler that is mounted in behind the Radiator. Hydraulic driven fans force ambient air across both cores. This cools the compressed combustion air and the engine coolant.

AIR INLET AND EXHAUST MANIFOLDS
Figure 3.11.2.4-1 illustrates the Air Intake Manifold and Figure 3.11.2.4-2 illustrates the Exhaust Manifold. The Air Inlet Manifold is located on the left side of the engine near the midway point. The Air Inlet Manifold is cast integrally with the 3456 engine cylinder head. The Exhaust Manifold is situated on the right side of the engine just below the turbocharger. The Exhaust Manifold connects directly to the cylinder heads, whereas the Air Inlet Manifold connects to the cylinder heads through Air Inlet Manifold Elbow. The Air Inlet Manifold distributes clean filtered air from the turbocharger and after cooler into each cylinder, while the exhaust manifold collects exhaust gasses from each cylinder and directs them to the turbocharger, then to the muffler.

MUFFLER ASSEMBLY
Figure 3.11.2.5-1 illustrates the Muffler Assembly (See Item 1). The Muffler Assembly reduces the exhaust-gas noise level and vents exhaust gases to atmosphere. Rain caps automatically open by exhaust gas pressure and close by use of counter weights. The rain cap is located at the end of the exhaust system and the muffler is an integral part of the PU roof (See Item 9).

AIR FILTER HIGH DIFFERENTIAL PRESSURE ALARM (HAFDPA)
Figure 3.11.2.6-1 illustrates the Air Filter High Differential Pressure Alarm (HAFDPA), located on the Generator Control Panel (GCP). The Alarm is activated after a fault is detected by continuous monitoring provided by the Air Filter Differential Gauge as shown in Figure 3.11.2.6-2. The Air Filter Differential Gauge is located inside the Power Unit below the engine-compartment cooling fan. The Air Filter Differential Gauge monitors restriction across the Air Filter. When the Air Filter High Differential Pressure Alarm light is lit, the Air Filter requires replacement.

ORT HARDWARE/SOFTWARE
The ORT provides DPGDS operators with a capability to conduct operations remotely, and provides maintainers with a capacity to conduct detailed maintenance diagnostics through communications with the Caterpillar Electronic Modular Control Panel (EMCP+), as well as the Caterpillar Electronic Technician (ET) Tool. Figure 3.12-1 illustrates the Operator Remote Terminal (ORT). The ORT is a Panasonic “ToughBook” notebook computer configured with software required to perform its functions as the ORT. The ORT Operator’s monitoring software runs on a preinstalled version of Microsoft Windows 2000 or XP. In addition to monitoring, the ORT includes the software and files necessary to configure and load the following MEP-PU-810 components: the PLC system and the overcurrent relays. The ORT may be loaded with Caterpillar’s Electronic Technician software to diagnose and troubleshoot the CAT 3456 engines.

ORT SCREENS
3.12.2.1
OVERVIEW SCREEN
There are two main screen types used in the ORT. The first screen type is the Overview Screen. This screen provides the operator with an overview of the complete DPGDS power plant system, up to a maximum of 4 PUs installed and connected. From this screen, the operator monitors the overall status of the system. No individual PU controlling is done from this screen. From this screen, the operator monitors overall system KW, number of generators required, and the following individual generator parameters: KW, total 3-phase voltage, total current, frequency, and power factor. Additionally, the operator can tell if the individual generators are running and if they are in automatic or manual mode.
FIGURE 3.12.2-1 3.12.2.2
OPERATOR’S REMOTE TERMINAL
INDIVIDUAL PU SCREENS
The second type of main screen is the individual PU monitoring/control screens. There is a screen for each individual PU, up to a maximum of 4. From the individual screen, the operator has control of the individual generators installed in each PU. This screen provides the operator with all the necessary information and controls to start, stop, parallel, or change lineup from the ORT. The operator also has control over the operation of individual PU breakers. This screen also informs the operator as to whether

USAF TO 35C2-3-518-1 USA TM 9-5115-484-14 DRS RADIAN CTM 01646.1R0253/1R0254 the PU is in Battleshort, mode of voltage regulation, engine economizing status and control, and fuel solenoid valve control. With the system operating in the automatic mode, by connecting an ORT to the network, the operator can monitor and control the Power Units from up to 150 feet away. From the ORT, the operator can operate all breakers and start/stop generators. The ORT has the capability to monitor and control a full system of four Power Units. From the ORT, the operator will receive indications that an alarm has occurred. The ORT will display which generator has the alarm. The operators can then make corrections or repair the problem before it causes the loss of a generator. The ORT also provides the operator with the capability of changing the lineup of online generators, as long as the number online stays the same. In a multiple PU lineup, the operator can disable engine economizing. This prevents the RTU from shutting down lightly loaded generators; however, in the event the load exceeds 85% and additional units are required, those units are added automatically by the RTU.

PLC and ORT load limiting software description Power monitor 60 Hz operation 50 Hz operation Warnings Battle short ORT load monitoring pop-up screens PDC AND ORT LOAD LIMITING SOFTWARE DESCRIPTION
The PLC and ORT overload software does not change the control/operation of the power unit under normal operating conditions. All operating procedures should be followed as specified in this technical manual, noting the power rating of the set is 420 kW prime for 60 Hz operation and 350 kW prime for 50 Hz operation. Software updates allow both the ORT and the PLC to warn the operator of an excessive load applied to the power unit. Additionally, the service pack adds additional functions and features to the ORT for improved operator interaction. 3.12.3.13.2
POWER MONITOR
The primary overload protection for continuous loads on the engine/generator is provided using the existing Generator Set Controller (GSC) and Programmable Logic Controller (PLC) in the PDC. New software has been added to the PU that will monitor the load and warn the operator if the power capability of the engine has been exceeded. If normal load levels are not established through load shedding or additional generators brought on line within the time allotted the unit will shut down to protect the engine/generator. 3.12.3.13.3
60 HZ OPERATION
Based on the 420 kW prime, 460 kW (110%) maximum rating of the generator, the load limits implemented are: (1) At 470 kW or 600 kVA the load limiting software warns the operator of an overload and the generator will shutdown in 8 minutes. * (2) At 480 kW or 615 kVA, the load limiting software warns the operator of an overload and the generator will shutdown in 2 minutes. * (3) At 500 kW or 630 kVA the generator will shutdown in 5 seconds. * The load must exceed this level for 5 seconds to activate the warning. When the generator load drops below 465 kW and 595 kVA the warnings will be extinguished.

Based on the 350 kW prime, 385 kW maximum rating of the generator, the load limits implemented are: (1) At 390 kW or 500 kVA the load limiting software warns the operator of an overload and the generator will shutdown in 8 minutes. * (2) At 400 kW or 512 kVA the load limiting software warns the operator of an overload and the generator will shutdown in 2 minutes. * (3) At 415 kW or 525 kVA the generator will shutdown in 5 seconds. * The load must exceed these levels for 5 seconds to activate the warning. When the generator load drops below 385 kW and 495 kVA the warnings will be extinguished. 3.12.3.13.5
WARNINGS
The operator warning is given in two ways. Additional fault lights indicating an overload have been added to the PU. When an overload is detected by the PLC, the existing PU fault annunciator will be turned on and the associated GENERATOR OVERLOAD light(s) will flash. A warning and countdown timer will be displayed on the Operator Remote Terminal (ORT) if it is in use. Two unique audible alarms have been implemented on the ORT signaling the 8-minute (470kW) or 2-minute (480kW) countdown periods. If the load on the unit is not reduced before expiration of the overload countdown timers the generator breaker will open and the engine will enter cooldown mode. The GENERATOR OVERLOAD lights on the PU will remain illuminated (steady state). See Figure 3.12.3.13.5-1. A generator overload fault can only be cleared from the PU using the MSES switch, Not from the ORT. If the Load is reduced to the 465 kW threshold for 5 seconds before the timers time out, the timers will reset and the audible alarm/faults will clear.

BATTLE SHORT
Activation of the Battle Short switch on the PU will override the shutdown of the unit except for Over Speed, Generator Basler Over Current Protection Relays, and Emergency Stop. If an overload condition is present the overload warning will be present but the overload timer will remain at 8 minutes and/or 2 minutes. WARNING Operating the unit in Battle Short can result in catastrophic failure of the engine and generator. When operating in Battle Short mode all PU’s are required to be placed in Battle Short mode. 3.12.3.13.7
ORT OVERLOAD POP-UP SCREENS
Two ORT load monitoring pop-up screens have been added to reflect over load timing functions and one new screen was added that details new features to the Overview Screen. Upon reaching an overload condition, as outlined above, the following will occur: (1) An alarm on the ORT is logged that must be acknowledged by the operator and warns of an overload condition. (2) An audible alarm on the ORT is activated and remains active as long as the generator is in an overload condition. (3) On the Plant Overview Screen, the overloaded generator(s) will flash and an overload countdown timer will be present as shown in Figure 3.12.3.13.7-1. (4) Upon reaching the second level of overload detection (480 kW for 60 Hz), a 2-minute warning will be displayed and a second audible warning (different tone) will sound on the ORT. This audible warning can only be extinguished by lowering the load on the generator below 465 kW. (5) When the overload condition reaches the 2-minute load level (480 kW at 60 HZ), this timer will override the 8-minute timer unless the generator is within 2 minutes of shutdown on the 8-minute timer. The timer that has the shortest shutdown time will then be displayed on the ORT screen. This means that if the generator is in an overload condition, (470 kW) and the load increases to 480 kW, the 2-minute timer will then activate, unless the generator is within 2 minutes of shutdown. If there are 2 minutes or less on the 8-minute timer, the 2-minute timer will not activate as that will add more time to the engine shutdown. (6) If the load is not reduced before the overload period expires the generator breaker opens and the generator enters the cooldown cycle. To re-enable the generator the fault must be cleared on the PU by toggling the Master Start Enable Switch for three seconds. The fault is then cleared and normal operation can resume. If the operator displays the PU Control and Monitoring Screen, during an overload condition, the screen will be shown as in Figure 3.12.3.13.7-2: Figure 3.12.3.13.7-3 shows new features added to the Plant Overview Screen

BRAKE SYSTEMS
3.13.3.1
MEP-PU-810A BRAKE SYSTEM
The hydraulic brakes on the MEP-PU-810A are much like those on a car. The hydraulic fluid from a master cylinder is used to actuate the wheel cylinder, which, in turn, applies force against the brake shoes and drum. The main difference between automotive hydraulic brakes and hydraulic trailer brakes are the actuation systems, which transfer the braking signal from the tow vehicle to the brakes. 3.13.3.1.1
SURGE BRAKING SYSTEM
Figure 3.13.3.1-1 illustrates the MEP-PU-810A Hydraulic Brake Actuator. The Surge Braking System uses a specially designed trailer hitch coupler, which has a built in master cylinder. When the tow vehicle applies its brakes, the tow vehicle decelerates causing the trailer to apply a pushing force against the towing vehicle hitch. This force actuates the surge hitch master cylinder, transferring high-pressure brake fluid to the wheel cylinder. The trailer brakes are now applied (See Figure 3.13.3.1-1).
FIGURE 3.13.3.1-1
HYDRAULIC BRAKE ACTUATOR
Figure 3.13.3.1-2 illustrates the Break-Away Lever and Chain positions. The surge brake system incorporates a safety breakaway lever and chain that activates the surge brake if the trailer separates from the tow vehicle. The actuator’s breakaway chain S-hook should be securely attached to one of the tow vehicle safety chain connection points. Before towing, check that the breakaway lever and chain are properly positioned as shown in (Figure 3.13.3.1-2). If the breakaway lever and chain are not located correctly, due to either the chain being pulled during use or by accident, it must be reset prior to moving the trailer. Resetting the lever is accomplished by first removing the two rearward bolts, located on each side of the breakaway lever. These two bolts hold down the breakaway locks. Loosen, but do not remove the remaining two bolts. This will allow the two locks to be swung aside and the lever can be pushed back into its resting position. Replace the breakaway locks to their original positions and retighten the four bolts using a torque wrench to 90-120 inch-pounds of torque.

3.13.3.1.3
HYDRAULIC BRAKE OPERATION
Figure 3.13.3.1.3-1 illustrates the Hydraulic Brake Function Diagram. The Hydraulic Brake utilizes a single acting cylinder. Upon actuation, the primary shoe is pressed against the brake drum, which causes the shoe to move in the direction of rotation. This movement in turn actuates the secondary shoe through the adjuster link assembly.

FIGURE 3.13.3.1.4-1 3.13.3.1.5
HYDRAULIC BRAKE COMPONENTS
SELF-ADJUSTING MECHANISM FOR HYDRAULIC BRAKES
The brakes adjust on both forward and reverse stops. Components include a new adjuster, adjuster lever arm, adjuster return springs, cable, cable anchor bracket, and an extension spring. The new cable anchor bracket fits over the anchor post and has a slotted hole. The extension spring attaches the cable anchor bracket to the primary brake shoe. The brake adjuster cable is routed from the cable anchor bracket, over the cable guide, to the adjuster lever. The forward stop adjustment is accomplished when the primary shoe lifts sufficiently far off the anchor post. The extension spring connecting the primary shoe to the slotted cable anchor bracket pulls the bracket and the cable causing the adjuster lever to rotate the adjuster screw star wheel. This will continue on each brake until the shoe clearance is sufficiently small so that the primary shoe movement is insufficient to pull the cable to engage the next tooth on the adjuster star wheel. 3.13.3.1.6
PARKING BRAKE
The parking feature for the MEP-PU-810A is a positive mechanical device that clamps against the inside rear tires when applied. The parking brake is engaged and disengaged using a crank handle located at the rear of the unit.

3.13.3.2
MEP-PU-810B BRAKE SYSTEM
Trailer air brakes are operated by the tractor air supply through a series of relays and check valves. When braking is desired, the air is supplied to the axle air chamber, which applies a force that is multiplied by the slack adjuster lever arm length. This force is transmitted rotationally through the camshaft, which, through the geometry of the S-head, spreads the brake shoes to contact the brake drum surface. 3.13.3.2.1
AIR CHAMBERS
Figure 3.13.3.2.1-1 illustrates the S-Cam Brake Assembly. The air chambers convert the tractor compressed air into mechanical force on the slack adjuster. The force on the slack adjuster operates on the end of the lever and converts the chamber output force to a torque on the S-cam. Federal and state regulations state the maximum pushrod stroke length as an indication of brake adjustment. The stroke length is indicated by the Maximum Stroke Indicator, located on the Air Chamber Pushrod. Maximum allowable stroke is achieved when the indicator is fully extended from the air chamber housing.
FIGURE 3.13.3.2.1-1 3.13.3.2.2
S-CAM BRAKE ASSEMBLY
SPRING BRAKES
For parking and emergency braking, a spring brake chamber is used in conjunction with the standard air chamber. The Spring Brake contains an additional air diaphragm and a very strong spring. When air pressure is applied to the spring brake, the spring is held in the off position by the air diaphragm. When the air pressure is released, the spring provides the braking force to the air chamber pushrod, thus activating the brakes.

3.13.3.2.3
SLACK ADJUSTERS
The Slack Adjuster performs two functions: (1) the slack adjuster acts as a lever arm to convert the linear pushrod force to rotational camshaft torque. The length of the slack adjuster determines the amount of torque multiplication provided from the pushrod. (2) Allows a simple external adjustment of the lining to drum clearance to compensate for shoe lining wear. Slack adjusters require manual adjustment to make up for the brake lining wear and the associated drum to lining gap that results. Adjustment is usually performed by rotating the hex nut on the slack adjuster body to set a lining to drum clearance of about .020-.030”.

BRAKE SYSTEM COMPONENTS
ANTI-LOCK BRAKE SYSTEM (ABS)
Figure 3.13.3.2.4-1 illustrates the Anti-Lock Brake System (ABS) Wiring Layout. The ABS is made up of Wheel Speed Sensors, an ABS Relay Valve, an integral Electronic Control Unit (ECU), mounted on the relay valve, and an ABS indicator light. The ECU monitors wheel speed through two-wheel speed sensors mounted on the hubs of the axle. When the ECU detects that a wheel is stopping too fast, during a brake application, the air pressure in the brake chambers of the wheels is reduced via the ABS Relay Valve, allowing the wheels to recover. The ECU then commands the relay valve to apply additional pressure unit maximum braking potential is produced. This ABS cycle is repeated roughly five times per second as needed, or until the vehicle is traveling at less than six miles per hour. NOTE:
The ABS system only functions when the PU is connected to the Tow Vehicles 12VDC electrical system; ABS will not function when connected to a 24VDC system.

The setpoints (stored or being programmed) must match the specified DPGDS setpoints.
② When oil pressure drops to within 5PSI (34kPa) of the P013 or P014 setpoint, a low oil pressure alarm is issued by the GSC+. ③ When coolant temperature rises to within 11ºF (6ºC) of the P015 setpoint, a high coolant temperature alarm is issued by the GSC+. ④ The values other than the default (700V) are for switchgear applications and require the use of external potential transformers and the removal of the AC voltage range jumper located in the relay module. The DPGDS unit is factory configured for the 5.20 K value. See the Caterpillar Electronic Modular Control Panel II+ manual topic AC Voltage Range Selection in the Testing and Adjusting section. ⑤ After setpoint P022 is reprogrammed, the GSC+ must be power cycled (powered down and then powered up)

PLANT OPERATIONS (AUTOMATIC MODE)
5.2.5.1
OPERATION SAFETY PROCEDURE
This mode of operation places control of all generator starting, stopping, synchronizing, and load management under the auspices of the Remote Terminal Unit (RTU) system. As long as the SMS is in AUTO, any generator started, manually or automatically, is automatically synchronized to the system bus. Care must be taken when starting a generator manually when the SMS is in AUTO. Either place the associated BCS in Pull-To-Lock (prevent closing to the bus) or ensure it has the red target visible (allow paralleling to the bus) before starting the engine. The only exception is automatic operation of the feeder breakers. Auto Mode does not automatically close feeder breakers; it only enables remote operation of the feeder breakers from the ORT. 5.2.5.2
DESCRIPTION
The master controller (the designated “A” unit) will control all connected generators based on the total system KW/KVA load. The controller shuts down one of the generators after 3 minutes should the system load drop below a level where the remaining generator load would not exceed 85% (360kW) if a generator is shutdown. If the load of the remaining generator exceeds 85% (360kW) for one minute, a standby generator is started and paralleled to the bus. A change of system load is recognized by the control system and appropriate action is taken to maintain generator load in the 85% (360kW/450 KVA) range. The system never automatically shuts down the final generator under normal operating conditions. The shutdown of the final generator must be done following manual operating procedures. The default configuration is Economizing Mode on. The economizing mode can be turned off from the ORT. Through the ORT, the AUTO shut down is disabled but the AUTO start-up remains active to prevent overloading the online generator(s).

n. Observe the KW, PF and KVAR of each generator at the LCP. Note: If adjustment is needed for KVAR balance, start with the generator that is the furthest from the average KVAR (either too low or too high). Make minor adjustments of the Voltage Adjust Rheostat (VAR) until the KVAR sharing between generators are within +/– 10% of the average plant KVAR load. This adjustment will typically be required only once during initial power plant setup and is intended to compensate for meter variations among generators.
CAUTION Improper adjustment of the VAR can cause a reverse KVAR shutdown of a generator.

PLANT OPERATIONS (AUTOMATIC MODE)
5.4.5.1
PRECAUTIONS AND WARNINGS
This mode of operation places control of all generator starting, stopping, synchronizing, and load management under the auspices of the Programmable Logic Controller (PLC) system. As long as the SMS is in AUTO, any generator started, manually or automatically, is automatically synchronized to the system bus. Care must be taken when starting a generator manually when the SMS is in AUTO. Either place the associated BCS in Pull-To-Lock (prevent closing to the bus) or ensure it has the red target visible (allow paralleling to the bus) before starting the engine. The only exception is automatic operation of the feeder breakers. Auto Mode does not automatically close feeder breakers; it only enables remote operation of the feeder breakers from the ORT.

DESCRIPTION
The master controller (the designated “A” unit) will control all connected generators based on the total system KW/KVA load. The controller shuts down one of the generators after 3 minutes should the system load drop below a level where the remaining generator load would not exceed 85% (360kW) if a generator is shutdown. If the load of the remaining generator exceeds 85% (360kW) for one minute, a standby generator is started and paralleled to the bus. A change of system load is recognized by the control system and appropriate action is taken to maintain generator load in the 85% (360 KW/450 KVA) range. The system never automatically shuts down the final generator under normal operating conditions. The shutdown of the final generator must be done following manual operating procedures. The default configuration is Economizing Mode on. The economizing mode can be turned off from the ORT. Through the ORT, the AUTO shut down is disabled but the AUTO start-up remains active to prevent overloading the online generator(s). 5.4.5.3
DEFAULT OPERATING SEQUENCE
Start-Up Sequence: The automatic controls will continuously monitor the system load. As load on the system increases, the controls automatically start and place additional units on line in the following sequence at 1-minute intervals: a. One generator from PU “B” based on lower engine runtime. b. Remaining generator from PU “A”. c. Remaining generator from PU “B”. Shutdown Sequence: Based on the loading experienced, the controller shuts down generator sets that are not needed. For the purpose of explanation, we will assume that all generator sets are on line following an initial startup. Based on load, the controls shut down generator sets in the following sequence at 3-minute intervals: a. One generator from PU “B” based on higher engine runtime. b. One generator from PU “A” based on higher engine runtime. c. Remaining generator from PU “B”. 5.4.6
