2.2. ADEM III Engine Control ler
2.2.1. IntroductionThe ADEM III controller is the main Electronic Control Module (ECM) used on the 3516Bdiesel engines.The ADEM III control is designed to control interface Electronic Unit Injector (EUI)equipped engines. The ADEM III controller is composed of the ADEM III ECM, controlsoftware, sensors, actuators, fuel injectors, and interface to the generator system.The prime benefit of an ADEM III engine system is to better control and maintain theparticulate emissions, both steady state and transient, while improving engineperformance over the Mechanical Unit Injector (MUI) engines.
2.2.2. Features
1 - General features
RELIABLE, DURABLE - All ADEM III controllers are designed to survive theharshest environments.Environmentally sealed, die-cast aluminum housing isolates and protectselectronic components from moisture and dirt contamination.Rigorous vibration testing ensures product reliability and durability.
Accuracy maintained from -40 C to +85 C.Electrical noise immunity to 100 volts/meter.Internal circuits are designed to withstand shorts to +battery and battery.
SIMPLE SERVICING -Each ADEM III system works in combination with the Caterpillar
ET service tool software to keep the engine operating at peak performance (notincluded). Displays measured parameters. Retrieves active and logged event codes documenting abnormal system
operation. Performs calibrations and diagnostic tests. Supports flash programming of new software into the ADEM III ECM.
SELF DIAGNOSTICS - Each ADEM III ECM has a full compliment of self diagnostics.The ECM can detect faults in the electrical system and report those faults to the servicetechnician for quick repair. Self-diagnostic capability pinpoints operational problems inneed of attention.

2-Advanced features
Isochronous or droop speed control. Enhanced performance from fuel injection timing and limiting. J1939 Communications. Adjustable monitoring of vital engine parameters. Idle/rated speed setting. Programmable speed acceleration ramp rate. Adjustable cooldown duration. Data link interfaces.
2.2.3. Description
The ECM is housed in an environmentally sealed casting. All wiring connections to theECM are made at the two sealed seventy-pin connectors.
ENGINE SPEED GOVERNING - Desired engine speed is calculated by the ECM andheld within 0.2 Hz for isochronous and droop mode. The ECM accounts for droop thatis requested. The proper amount of fuel is sent to the injectors due to these calculations.The ECM also employs cooldown/shutdown strategies, acceleration delays on startup,acceleration ramp times, speed reference and a low/high idle switch is also available viacommunications to the EMCP 3.3 generator mounted local control panel.
FUEL LIMITING - Warm and cold fuel-air ratio control limits are controlled by the ECM.Electronic monitoring system derates, torque limit, and cranking limit, programmabletorque scaling, and cold cylinder cutout mode are standard features.
FUEL INJECTION TIMING - Master timing for injection is controlled by the ECM control.
Temperature dependencies are accounted for in the fuel injection calculations.
ELECTRONIC MONITORING - Electronic monitoring of vital engine parameters can beprogrammed. Warning, derate and shutdown event conditions may be customized by theuser.
INFORMATION MANAGEMENT -The ECM stores information to assist with electronictroubleshooting. Active and logged diagnostic codes, active events, logged events, fuelconsumption, engine hours, and instantaneous totals aid service technicians whendiagnosing electronic faults and scheduling preventive maintenance.
CALIBRATIONS - Engine performance is optimized through injection timing.Auto/manual sensor calibrations are standard features.
ON-BOARD SYSTEM TESTS - System tests are available to assist in electronictroubleshooting. These tests include: injector activation, injector cutout, and override ofcontrol outputs.

3.3. Form Wound Stator Winding before Impregnation Coils fit precisely into slots, without voids, giving better mechanical and electrical
strength. Crimped and soldered lead connections. Large spaces between symmetrical coils:
o Improves winding coolingo Reduces moisture retention
Lacing, double surge ropes, and blocking of coil end turns minimizes coilmovement during surges.
Insulation Each stator is vacuum pressure impregnated (VPI) with class Hpolyester insulation material. Each stator is then sealed with a class H epoxymaterial for excellent abrasion protection.
3.4. Rotor construction
The exciter rotor is machine wound and receives two dips and bakes of a fungus-resisting resin.The main rotor uses a precision wet layer wound process, with epoxy painted on thebare rotor and on each layer. This ensures bonding of all the wire layers together,bonding of the coils to the rotor laminations, and a sealed insulation system. The rotorepoxy is then oven-cured.

6. Switchgear
6.1. ControlsCaterpillar Utility paralleling switchgear is intended for automatic or manual parallelingwith a utility power source as a load management system, with provisions for standbyoperation feeding an isolated load network. Modes of operation are field configurableand include:
Single Unit Island Mode.
Multiple Unit Island Mode (up to 10 units).o Includes Load Sense / Load Demand control.o Load sharing capability is provided via network communication.
Single Unit Utility Parallel Mode.o Automatic paralleling.o Selectable for Import / Export control. (Requires 4-20 mA customer input.)
6.1.1. Incoming Utili ty Breaker Status Circuit
Circuit to accept customers contact from remote utility disconnect device. Customer toprovide a normally open form a contact to indicate when the local load network isconnected to the utility grid.
6.1.2. Utility Transfer Trip Circuit
Circuit accepts input (normally open dry contact) from customer's system protectiverelay(s) or other controlling device. Operation of contacts causes tripping of thegenerator circuit breaker via the generator lock-out relay (ANSI device 86) and places
the engine in cooldown mode. Circuit is disabled when operating in single unit or multipleunit island modes.
6.2. Monitoring

7. Testing
7.1. Prototype TestingThe Caterpillar Utility Power Module has extensive prototype testing and validations.This includes an 8 hr. of the load test with the following parameters will be recorded:
Fuel rate and specific fuel consumption
Frequency and speed
Real and reactive power
Power factor
Jacket water temperature
Oil pressure
Fuel pressure
Phase voltages and currents
Sound level measurements
7.2. Standard Power Module TestTesting for production power module switchgear containing generator set controller(GSC), GSC+, and microprocessor based intertie and generator protection relays. Thepurpose of this power module switchgear test procedure is to:
Verify the programs contained in the generator protection relay and the intertieprotection relay.
Verify that the GSC panel has been properly programmed.
Verify the setting of the trip unit contained in the main circuit breaker.
Verify all switch gear metering.
Verify stand-by operation using both local and remote start/stop.
Verify parallel operation using both local and remote start/stop.
Verify both manual and automatic base-load control using both local and remotestart/stop.
Check the setting of the generator mounted voltage regulator.
Set the isochrous governor and load share module.
Check the mechanical and electrical integrity of the power module switchgearassembly.
Because generator set engines and the generators have been pre-tested, this test is notintended to provide a measurement of the generator set power capability.
Note: Power Module will be tested at 60hz first then tested at 50hz and will leave thefactory at 50hz.
Prior to the testing described herein, the engine and the generator and the gensetpackage shall be pretested by their respective manufacturer's normal production teststandards. These tests will be recorded and available for review at the Power Modulewitness test.
