The two engines are Caterpillar 3456 EPG Engines. They are Liquid-cooled, 6 cylinder, four-cycle, turbo-charged, and after-cooled and have a 15.8 Liter (964 cubic inch) displacement.
Both Generators are Caterpillar model SR4B. The generator is a brushless, rotating armature exciter,
single-bearing, air-cooled, open drip-proof unit. The generator is directly connected to the engine. Thegenerator is a permanent magnet pilot excited (PMPE) generator that receives power for the voltageregulator from the pilot exciter, rather than the main armature as in self-excited generators. The pilotexciter consists of permanent magnet (PM) rotor and PM armature (stator). The pilot exciter operatesindependently. The generator is Wye connected. For 60 Hz operation the output is 4160 volts line to line,2400 volts line to neutral, 3 phase, 4 wire, Wye connected generator. For 50 Hz operation the output is3800 volts, 3800 volts line to line, 2200 volts line to neutral, 3 phase, 4 wire, Wye connected generator.
The housing is a weather-tight enclosure that provides access for maintenance, overhaul, or replacementof major components. For proper airflow through the PU housing, all doors must be closed while the unitis running.
Lifting and Tie-downs - The van has standard ISO corner fittings on the top 4 corners for lifting by
a standard 20 foot ISO lifting frame using ISO Extenders, see Figure 2.1-1 and Figure 2.1-4. OneISO Extender is needed for each ISO Fitting on the PU. Although the van has ISO features it isNOT stackable. - The van has tie-down features rated to meet the system.
Engine Fluid Drains - Each PU is provided with a serviceable means of draining engine fluidssuch as oil, coolant and fuel through the bottom exterior of the van.

Floor Vents - A section of the floor under the generators in the engine-generator compartment isventilated to allow air to be drawn through the compartment for ventilation air and enginecombustion air. A shield is provided below the floor vents to minimize debris such as rocks or dirt
from being thrown into the generator compartment during towing.
Grounding Lug Two Ground lugs are provided on the PU for connecting the external groundconnections. The ground lugs are a 4/0 split-bolt copper lug and are designed for repeated use.The ground lugs are located under the Local Control Panel (LCP). Refer to figures 5.1.3.1-1 and5.1.3.1-3 for the A and B models grounding lug locations.
2.2 DIFFERENCES BETWEEN VERSIONS
The "A" and "B" versions differ due to the two styles of trailers and associated hardware. See Table 2.2-1.
TABLE 2.2-1 DIFFERENCES BETWEEN VERSIONS
TRAILERTOWINGHITCH
The "A" version PU uses a trailer lunette with a 3 inch inside diameter. It hooks to thetow pintle of the towing vehicle. The "B" version PU uses a fifth wheel, which slides onand hooks to the fifth wheel plate of the towing vehicle.
RUNNINGBRAKES
The A version uses a surge brake system that is an integral part of the towing hitch.When braking, trailer inertia pushes a rod against the master cylinder and applies thetrailer brakes using a conventional hydraulic system. The B version uses a standardair DOT anti-lock brake system (ABS) for fifth wheel trailers. It includes a full functionservice and spring brake valve, ABS control module, service and supply hoses, gladhands, and a 2,800 cu. in. air tank.
BRAKES
The parking brake on the A version is a mechanical manual crank devise that clampsover the inside rear tires. The B version uses an air control spring brake system.When the trailer is being towed, powerful springs in the brake chamber are held back by
air pressure. When the parking brakes are applied or the PU is disconnected, airpressure is released from the chamber and the springs apply mechanical brakes toeach wheel hub.
VAN LIGHTS
The "B" version PU trailer has lights for clearance, reflectors, turn signals, and tail/stop-lights in accordance with Department Of Transportation (DOT) and Federal MotorVehicle Safety Standard (FMVSS), 121, 571.124 standards for commercial operations.For towing with a commercial truck, the commercial lights are powered by the vehicle12-volt electrical system and are provided with a 7-way intervehicular cable. Inaddition, a set of blackout lights including clearance, reflectors, turn signal, andtail/stop-lights powered by the vehicle 24-volt electrical system. A 12-way intervehicularcable is provided for towing with military vehicles. When in the blackout mode ofoperation, the commercial lights are non-operational
STEPSThe "B" version trailer is provided with a commercial ladder to allow access into the PUtrailer at any of the PU side doors. Ladder storage is above the PDC within the interiorPU when the ladder is not in use or during transportation of the PU.
TIRES The A version is provided with a LT235/85R16 with a load range of E.
TIRES The B version is provided with a 11R22.5 with a load range of G.
STORAGE The B version has a general cargo storage box 24IN. x 24IN. x 54IN.

3.2.3 PRIMARY DISTRIBUTION CENTER (PDC) EQUIPMENT
The Local Control Panel Assembly, as illustrated in Figure 3.2.3-1, provides local control for the PowerUnit (PU). Located at the rear of the PU, the Local Control Panel (LCP) contains the Master Control
Panel (MCP), and the Generator Control Panel (GCP) for Generator 1 and Generator 2. All Automatic
and Manual operations are controlled from these panels.
The Local Control Panel (LCP) allows the operator the flexibility of controlling operations from the GCPs
including the ability to start, stop, add and remove load, parallel in and add or remove units from the bus,
as well as monitor all control functions. A capability for remote operations is provided through the
addition of a Operator Remote Terminal (ORT).

From the Generator Control Panel (GCP), the operator can manually start, stop, control, and operate theassociated generator and feeder breakers. Additionally the operator can observe engine and generator
parameters at the Generator Set Control GSC+ module. There are current protective relays installed inthe GCP for generator and feeder breaker protection. All controls and indicators described in this sectionrefer to the Generator 1 GCP and use the applicable component marking (A suffix) references. Thefollowing controls and indicators of the G1 GCP as illustrated in Figure 3.2.3.1-1 are:
a. System in Battleshort Mode Light(SBL)
This amber LED indicates that the PU is in Battleshort mode. This status is visible at both generatorcontrol panels, as it is common for both generators.
b. Primary Fuel Filter High Differential Alarm Light(HPFFDPL)
This amber LED indicates that the associated engine primary fuel filter has reached the highdifferential pressure setpoint and needs to be inspected and the filter replaced.
c. Secondary Fuel Filter High Differential Alarm Light(HSFFDPL)
This amber LED indicates that the associated engine secondary fuel filter has reached the highdifferential pressure setpoint and needs to be inspected and the filter replaced.
d. Primary Fuel Filter High Water Level Alarm Light(PFFHWLL)
This amber LED indicates that the associated engine fuel filter has reached the high level of wateraccumulated in the bowl setpoint and needs to be inspected and the bowl drained.
e. Oil Filter High Differential Alarm Light(HOFDPL)
This amber LED indicates that the associated engine oil filter has reached the high differentialpressure setpoint and needs to be inspected and the filter replaced.
f. Air Filter High Differential Alarm Light (HAFDPL)
This amber LED indicates that the associated engine air filter has reached the high differentialpressure setpoint and needs to be inspected and the filter replaced.
g. Fuel Tank High Level Alarm Light (HFTLL)
This amber LED indicates that the PU common fuel tank has a high fuel level. The fuel transfer pumpneeds to be checked to ensure that it is not running to prevent overflowing the tank.
h. Fuel Tank Low Level Alarm Light (LFTLL)
This amber LED indicates that the common fuel tank level is low. Verify the fuel transfer pump isrunning and make-up fuel is being transferred to the PU. Both generator sets can be operated at fullload in this condition for a maximum period of 10 minutes. The control system will automatically shutdown operating generator sets and prevent restarting until the fuel level reaches the minimumallowable level.

3.2.3.1.2 DETAILED DISCUSSION OF CONTROLS AND INDICATORS
3.2.3.1.2.1 GSC+ GENERATOR SET CONTROL
The GSC+ provides control for the engine/generator and local monitoring for its associated generator set.All metering parameters are available from the GSC+. The GSC+ monitors and controls many of theengine functions. Some of the more basic checks that the operator will be required to perform on aroutine operating basis have been provided for convenience.
The GSC+ is covered in detail in the Caterpillar service manual. For further operational instructions onusing the GSC+ see the Caterpillar (See RENR-1200 or later) manual (See Figure 3.2.3.1-1, Item 10).
3.2.3.1.2.1.1 FUNCTIONS
The GSC+ is designed to operate with a 24VDC battery system. The GSC+ monitors and controls manyof the generator set functions. The functions and features of the GSC+ are:
a. Provides generator AC output information including power metering.
b. Controls starting and stopping of the engine based on the input from the Engine Control Switch(ECS), and/or the internal Programmable Logic Computer (RTU).
c. Shows engine condition and generator output information on two displays. These displays alsoshow fault codes and GSC+ programming information.
d. Monitors the system for faults. If a fault occurs, the GSC+ performs a controlled fault shutdownor provides a fault alarm annunciation. The GSC+ uses indicators and displays to describe the
fault to the operator.
e. Contains programming features for the DPGDS system.
3.2.3.1.2.1.2 DISPLAYS
Upper Display:
The primary function of the upper display is to show AC voltage, current and frequency information of thegenerator output. There are several options available. These options can be viewed one at a time bypressing the AC meter key on the keypad:
Voltage (average), frequency, and current (total)
Voltage (line to line), frequency, or current on any phase
Current (line) for all three phases at once
Various fault codes for system faults. For detailed information on fault codes refer to theCaterpillar service manual.

Lower Display:
The lower display shows values for power metering, engine parameters and the relay status. The leftside of the lower display functions as a generator set power meter. The following functions scrollautomatically:
Total real power (kW)
Total reactive power (kVAR)
Percent of rated power
Power factor
Total energy output (kVA)
Briefly pressing the Power Meter keypad will cause the display to start scrolling. Pressing a second timewill display the parameter continuously, indicated by the parameter label flashing.
The right side of the lower display shows the value of certain engine parameters. The parameters shownare:
System battery voltage (VDC)
Engine run time (Hours)
Engine speed (RPM)
Engine oil pressure (PSI)
Engine coolant temperature (F)
The value of each of these parameters is shown for two seconds and then the display scrolls to the nextparameter. A small pointer identifies the engine condition being displayed. When the Engine Meter keyis depressed, the information screen stops scrolling and continuously displays the selected parameter.
