1 GENERAL INFORMATION

1.1 COMPANION MEDIA NUMBER

This document has media number, LEBE5255.

It also has a companion media number, LERE5255. If only one of the media numbers is ordered, the other is shipped automatically, but separately. LERE5255 is a mini-CD that contains printable files of schematics found in this document on pages 112,13,14 1, APPENDIX H (page 248).

1.2 INTRODUCTION

Caterpillar® has developed a product line of Generator Set Controls for use in the Electronic Modular Control Panel 3 (EMCP 3). They are available in three versions based on Generator Set Control feature sets.

The EMCP 3 Generator Set Control, or GSC, is the primary controller within the Generator Set Control system. It contains the primary operator and service interface. The inset photo shows an up-close view of the EMCP 3.3. The EMCP 3 line of Generator Set Controllers includes EMCP 3.1, 3.2, and 3.3. APPENDIX I shows a full view of the EMCP 3.3.

This Application and Installation Guide is intended to cover the EMCP 3 Generator Set Control and its application in generator set systems. The intended audience for this guide includes Caterpillar generator set system designers, Caterpillar service support personnel, Caterpillar Dealers and Service Technicians, contractors, and customers.

1.3 APPLICATIONS

The EMCP 3 GSC product line of generator set controllers is designed for use in a wide range of applications. They can be used on standby and prime power diesel generator sets including Caterpillar®, FG Wilson®, and Olympian® brands. The configurability of the controllers allows them to be used, in some cases, on other applications such as Marine auxiliary generators, switchgear applications, industrial engines and generator sets, and gas generator sets.

Most of the information in this document applies to all applications. However, the document was written with Caterpillar brand diesel generator sets in mind. Please contact your Caterpillar support representative for questions regarding different applications.

2 SAFETY Information

2 SAFETY INFORMATION

2.1 ELECTRICAL SAFETY

DO NOT operate or work on a generator set unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Caterpillar dealer for replacement manuals. Proper care is your responsibility.

2.2 ELECTROSTATIC DISCHARGE AWARENESS

EMCP 3 GSC control contains components that are sensitive to ELECTROSTATIC DISCHARGE (ESD). An electrostatic charge can damage the control resulting in EMCP 3 GSC breakdown or improper operation.

Take the following precautions while installing/removing/handling the control:

• Handle equipment correctly. Use ESD protective packaging and material handling containers that are anti-static and provide discharge protection and electric field suppression.

• Use protective devices: ESD-protective workstations and/or work surfaces (grounding mat, anti-static wrist strap, etc).

• Keep all plastic items away from the devices. Any plastic item is a potential static generator. This includes candy wrappers, foam cups, synthetic carpet, foam cushions, etc.

• The anti-static bag cannot function as a static dissipating mat.

• DO NOT use an anti-static bag for any other purpose than to enclose a product.

CAUTION: The 70-pin connector on the back of the control is the most vulnerable area to ELECTROSTATIC DISCHARGE (ESD). While handling the EMCP 3 GSC, extra attention is required to the back of the control. The control may become damaged or inoperable if extra care is not taken.

Consult the Electrostatic Discharge Association for proper procedure during particular situations: http://www.esda.org http://www.esda.org/

3 INSTALLATION

3 INSTALLATION

3.1 MOUNTING LOCATION

When selecting a mounting location for the EMCP 3 GSC, consider the following:

• Protection from high-voltage and high-current devices.

• Protection from devices which may produce electromagnetic interference.

• Protection from excessive vibration. The controls are designed to withstand normal generator set vibrations. The controls should not be mounted directly to the engine block.

• Protection from direct exposure to water. Once installed, the EMCP 3.1, 3.2, and 3.3 are sealed to a level of IP Level 22 for resistance to moisture.

3.2 OPERATING TEMPERATURE RANGE

EMCP 3 GSC has a continuous operating temperature range of –20°C to +70 °C ambient.

3.3 POWER REQUIREMENTS

The EMCP 3 GSC requires a nominal voltage of 12 V DC or 24 V DC. If batteries are used for operating power, a charging source such as an alternator or dual-mode battery charger is necessary to maintain a stable supply voltage. Under steady state operation, the EMCP 3 GSC will draw approximately 0.5 A to 1.5 A current draw (not including any relay loads).

Regional electrical codes must be followed. In the case of standby operation, follow the regional requirements for installing standby power systems. An example of this is the National Fire Protection Association (NFPA) guidelines for emergency power systems.

When connecting the EMCP 3 GSC to the DC power source, make sure that there is only one common connection to the negative potential of the power source. Make extra effort to avoid any ground loops in the DC electrical system. A single point common ground for sensitive electronics is recommended at the negative battery terminal or Power Distribution Box.

Avoid daisy-chaining power supply connections from one device to another. This builds resistance from one (-)Battery point to the next, effectively building a potential difference between two different reference points. Each electronics subsystem and major engine subsystem should have its own DC network so that they do not interfere with each other (see

FIGURE 1).

As shown in FIGURE 1, all sensitive electronics are electrically isolated from higher current loads, such as the starter motor. All electronics have a COMMON POWER BUS and SINGLE POINT REFERENCE. The CHASSIS GROUND is a common POWER AND TRANSIENT GROUND.

The sensitive electronics, such as sensors and control modules, have isolated power source paths. High current loads such as starters and solenoids can cause interference and possibly damage to low current loads, such as controllers and sensors.

CAUTION: Extra effort must be made to keep the high current and low current loads electrically separated.

FIGURE 1: GENERATOR SET NETWORK ISOLATION

The two types of loads may share common Battery (+) and Battery (–) connections but, they should not be electrically connected at any other point. This strategy ensures maximum isolation between high current and low current loads.

The battery DISCONNECT SWITCH is located on the negative leg of the battery supply.

3.4 BATTERY CHARGER

If a battery charger is to be used, it should be connected on the battery side of the disconnect switch, so as not to power the electronics. Most battery chargers are not to be used as power supplies. Proper battery charger operation requires that the actual battery load is present.

3.5 ELECTRICAL CONNECTIONS

The EMCP 3 GSC has one 70-pin connector on the back of the control and not all of the 70 pins are used.

FIGURE 2, FIGURE 3, and FIGURE 4 show:

• All possible connections

• What pins are used for connections

• How each pin is connected for each control version

3.6 EUI ENGINES

For EUI engines, the PASSIVE ANALOG INPUTS #1 and #2 will NOT be used. These are for discrete oil pressure and coolant temperature sensors, respectively. These sensors will be wired to the engine ECM and the EMCP 3 GSC will get that information from the engine ECM via the Primary J1939 Data Link.

For more information about the passive inputs, see Chapter 9, ANALOG INPUTS.

ANALOG CONNECTIONS

The 70-pin connector wiring diagrams below, also, show two different ways to connect the analog inputs.

• Connections for 2-wire sensors are shown (including all of the other connections).

• Connections for 1-wire sensors are shown at the bottom right hand side of the figures.

DISCRETE INPUTS

The discrete inputs are shown connected through NORMALLY OPEN contacts to battery negative.

These inputs can also be connected through NORMALLY CLOSED contacts to battery negative. To do this the ACTIVE STATE of the input will need to be set to ACTIVE HIGH.

For information on software configuration of the digital inputs see Chapter 8, Digital Inputs.

FIGURE 3: EMCP 3.2 ELECTRICAL DIAGRAM

FIGURE 4: EMCP 3.3 ELECTRICAL DIAGRAM

3.8 WINDING CONNECTIONS

The connections between the generator and the EMCP 3 GSC depend on the winding configuration as shown in the connection diagrams below.

FIGURE 5: THREE PHASE FOUR WIRE (SERIES OR PARALLEL) WYE (STAR)

FIGURE 6: THREE PHASE FOUR WIRE DELTA

FIGURE 7: THREE PHASE THREE WIRE DELTA

FIGURE 8: SINGLE PHASE THREE WIRE (DOUBLE DELTA)

FIGURE 9: SINGLE PHASE TWO WIRE (DOUBLE DELTA)

3.9 TRANSFORMER CONNECTIONS

In order to monitor generator output voltages greater than 600 Volts, external potential transformers must be used.

NOTE: The EMCP 3 GSC must be programmed for the correct winding ratios when connecting external potential transformers. See Chapter 7, Setpoints for more information on how to program the winding ratios.

CAUTION: The WYE configuration of external potential transformers is preferred for 4-wire wye generators because of the greater accuracy when loads are unbalanced.

With the open delta configuration, some power parameters can not be determined. These parameters are real power phase A, B, C and power factor phase A, B, C. For maximum accuracy, the open delta configuration of external potential transformers should be used only for 3-wire delta generators. Refer to Table 1: Power Values Valid by Generator Configuration, page 17.

(1) The number of connections must be kept to a minimum.

3.11 SHIELDED WIRING

Shielded twisted pair cable is required for the J1939 datalink and the magnetic speed sensor.

This cable is used for maximum protection against inductive noise, electromagnetic interference, and radio frequency interference. The shield greatly reduces the amplitude of any unwanted voltages on the signal wire. If the shields are connected to sheet metal, the connections are susceptible to loose bolts, corrosion, etc. The faulty connections increase the resistance of the shield. Faulty connections also reduce the effectiveness of the shield.

All the shields of the shielded cable must be connected to the common battery negative terminal of the generator set only. The shields should not be connected to the sheet metal. Sheet Metal connections corrode over time, increasing the resistance on the shield. When the cable terminates at junction boxes, the shields must be connected to each other in order to maintain a continuous path. Wire exposed beyond the shield should be as short as possible and not exceeding two inches. To avoid ground loops, shields should be grounded at one point only.

To avoid electromagnetic interference, do not run shielded signal wires near other wires carrying large currents. In installations with unavoidable risk of electromagnetic interference (EMI), shielded wire run in conduit, extra shielding, or other precautions may be necessary.

4.3 CONFIGURING TIME/DATE (EMCP 3.2 AND 3.3)

The EMCP 3.2 and 3.3 have an internal clock that is used for time-stamping events. The timestamps for the first date and time an event has occurred and the last date and time the event has occurred are viewed by selecting an Event and pressing Enter, then scrolling down.

See FIGURE 14 below.

FIGURE 14: EVENT DETAILS SCREENS – LAST OCCURRENCE (LEFT) AND FIRST OCCURRENCE (RIGHT)

CHANGING DATE FORMAT

The data format can be set to either display in the form Month/Day/Year or the form Day/Month/Year. This procedure must be performed on the EMCP 3 GSC display; it cannot be done using the Caterpillar Service Tool.

NOTE: This preference does not affect operation of the EMCP 3 or the data as viewed in the Caterpillar Service Tool. It only affects how the date is displayed on the EMCP 3 GSC display.

To change the date format, do the following:

At MAIN MENU

ENTER KEY

SCROLL DOWN

to CONFIGURE to TIME/DATE

Highlight FORMAT MM/DD/YY

(or FORMAT DD/MM/YY, depending on the current setting)

Select the format using the

LEFT ARROW or RIGHT

ARROW

CHANGING THE TIME / DATE

The EMCP 3 clock allows the time/date to be modified. Changing the time/date will change the timestamp on all future events, but not for existing events. (For example, an event that has occurred previously will still show the same FIRST time/date, but if it occurs again after the time/date has been adjusted, the LAST time/date will reflect the change.)

This procedure must be performed on the EMCP 3 GSC display; it cannot be done using the Caterpillar Service Tool. In order to update time/date, LEVEL 1 ACCESS is required. Refer to Chapter 6, Security for information on obtaining LEVEL 1 ACCESS.

To change the time/date, do the following:

4.4 ADJUSTING GENERATOR SET PARAMETERS

On some gensets, the engine speed, generator output voltage, and idle/rated status can be adjusted from the display of the EMCP 3 GSC.

ENGINE SPEED

To program the Engine Speed of a genset it must have an electronic engine controlled by an ADEM III or newer ECM. The Primary Desired Speed Input Configuration Setpoint in the ADEM is programmed to CAN INPUT, then the engine speed can be adjusted from the display of the EMCP 3 GSC. The Engine Type Configuration setpoint must be programmed to ELECTRONIC.

PROGRAMMING THE ENGINE SPEED

From the MAIN MENU select CONTROL

Once in that screen the first option will be highlighted and it will display one of the following: SPEED, VOLTAGE, or SPEED & VOLTAGE. The engine speed can only be controlled if SPEED or SPEED & VOLTAGE is displayed. If the EMCP 3 GSC is not programmed for an electronic engine, speed will not show up as an option.

Press the ENTER KEY The speed and voltage adjust screen will be displayed. To adjust the engine speed from this screen

Adjust Engine Speed:

Press RIGHT ARROW KEY To INCREASE the engine speed

Press LEFT ARROW KEY To DECREASE the engine speed

The EMCP 3 GSC will broadcast an engine speed bias based on the adjustment that is made.

If the engine speed is adjusted, that value will remain until either it is adjusted again or until the control is power-cycled.

GENERATOR OUTPUT VOLTAGE

If the genset is equipped with a Caterpillar Digital Voltage Regulator (CDVR), then the generator output voltage can be adjusted from the display of the EMCP 3 GSC.

PROGRAMMING THE GENERATOR OUTPUT VOLTAGE

Once in that screen the first option will be highlighted and it will display one of the following: SPEED, VOLTAGE, or SPEED & VOLTAGE. The generator output voltage can only be controlled if VOLTAGE or SPEED & VOLTAGE is displayed.

Press the ENTER KEY The speed and voltage adjust screen will be displayed. To adjust the generator output voltage from this screen

Adjust Output Voltage:

Press UP ARROW KEY To INCREASE the generator output voltage.

Press DOWN ARROW KEY To DECREASE the generator output voltage.

NOTE: In order for the VOLTAGE ADJUST to work, the AVR VOLTAGE CONTROL DESIRED INPUT CONFIGURATION setpoint in the CDVR must be programmed for CAN INPUT. If that setpoint is set to SWITCH, the VOLTAGE CONTROL from the EMCP 3 GSC will NOT WORK.

IDLE/RATED

The engine speed can be toggled between LOW IDLE and RATED SPEED from the display of the control.

Press DOWN ARROW Highlight IDLE/RATED.

The IDLE/RATED screen will be displayed and the current state will be shown.

To change the state, Press UP ARROW or DOWN

ARROW Then select the value.

Press ENTER KEY

4.5 STARTING AND STOPPING THE GENERATOR SET

STARTING THE ENGINE

Once the control is configured correctly, the control panel is powered up, and the generator set is ready to be operated, the generator set can be started. Refer to FIGURE 15, Stopping The Engine. There are several ways the generator set can be started from the control panel.

To START the engine in MANUAL OPERATION:

1. Press the RUN KEY or

2. Place the control in AUTO mode then

3. The engine can be started THREE DIFFERENT WAYS.

a: Activate DIGITAL INPUT #2, which is the REMOTE INITIATE INPUT.

b: Activate a REMOTE INITIATE over the MODBUS data link.

c: Configure a PROGRAMMABLE CYCLE TIMER.

When the control panel initiates a start command on a diesel engine, the control checks to make sure there are no SHUTDOWN EVENTS present (labeled PRESENT) or that there are no latched SHUTDOWN EVENTS (labeled ACTIVE).

If there are no shutdown events that are active or present, and after any pre-crank or start-aid activities have completed, the starter motor and fuel control will be activated. The EMCP 3 GSC will activate Relay Output #1 to activate the starter motor magnetic switch, and Relay Output #2 to activate the fuel enable circuit.

On electronic engines with ADEM™ A3 or newer engine ECM, the start command and fuel enable signals will be sent from the EMCP 3 GSC to the engine ECM via the J1939 data link.

After receiving the signals, the engine ECM will operate the fuel control relay and starter motor magnetic switch. Relay outputs #1 and #2 will not be used on those engines.

Relay Output #1 will remain active until the programmed ENGINE CRANK TIME has been reached, or until the engine speed has reached the programmed CRANK TERMINATE SPEED setpoint value.

NOTE: the EMCP 3 GSC Crank setpoints: number of cranks, crank duration, and crank terminate speed are not used on engines using the ADEM™ A4 with the Common Engine Interface option or newer engine ECM. These values must be adjusted in the engine ECM.

CAUTION: To determine the exact starting sequence for your engine, consult your engine’s Operation and Maintenance Manual.

STOPPING THE ENGINE

Once the engine is started, the engine can be stopped by pressing the STOP KEY on the control panel. If the control is in AUTO, the engine can also be stopped by DEACTIVATING all of the remote initiate commands. There are three possible sources for this command:

1. The remote initiate input (digital input #2)

2. The remote initial command over the Modbus datalink (register number 1055)

3. The Programmable Cycle Timer

Once the STOP command is issued, the control will go into COOLDOWN MODE. Cooldown mode will run for the duration of time that it is programmed in the COOLDOWN DURATION setpoint. If the cooldown time is set for zero minutes, the engine will stop immediately.

On engines with ADEM™ A4 or newer engine ECM, the cooldown timer in the EMCP 3 GSC should be set to 0 (Zero) minutes because the cooldown time is controlled from the engine ECM (if this is not done, both cooldown timers will run in sequence). Also, the ENGINE OPERATING STATE INPUT CONFIGURATION parameter must be set to CAN INPUT.

The cooldown timer can be overridden by pressing and holding the STOP KEY for 5 seconds. The display will show a splash screen that will ask if you want to BYPASS COOLDOWN?

or continue with the cooldown cycle.

If the ENTER KEY is pressed from the splash screen, the cooldown timer will be bypassed.

If the ESCAPE KEY is pressed from the splash screen, the cooldown cycle will continue until the programmed cooldown time has elapsed.

When the cooldown timer has elapsed or has been bypassed, Relay Output #2 will open. The STOP command will also be sent over the J1939 data link for those engines that require it. At that point, the fuel injection will be DISABLED and the engine will stop.

Any time, while the engine is RUNNING:

The EMCP 3 GSC detects a condition where an engine or generator parameter is ABOVE or BELOW programmed thresholds for a programmed amount of time or another SHUTDOWN EVENT occurs, then the EMCP 3 GSC will attempt to shut the engine down

Depending on how a specific EVENT RESPONSE configuration is programmed, the EMCP 3 GSC will either put the engine in COOLDOWN, followed by a soft shutdown or shut the engine down immediately (a HARD SHUTDOWN).

FIGURE 15: STOPPING THE ENGINE

4.6 ENGINE SETPOINT VERIFICATION

The engine setpoint verification procedure verifies that the EMCP 3 GSC operates correctly when OIL PRESSURE, HIGH COOLANT TEMPERATURE, LOW OR ENGINE OVERSPEED events occur.

On an ENGINE OVERSPEED EVENT, the EMCP 3 GSC will shut the engine down.

LOW OIL PRESSURE and HIGH COOLANT TEMPERATURE each have two events, WARNING and SHUTDOWN. The EMCP 3 GSC will issue a WARNING whenever the warning threshold is reached and a SHUTDOWN whenever the shutdown threshold is reached. The configuration setpoints used in normal operation will be modified.

During this procedure

Each configuration setpoint should be recorded prior to adjustment.

Returned back to the original setting after the setpoint has been verified.

The following conditions are required before the ENGINE SETPOINTS are verified:

REQUIRED CONDITIONS

The setpoints must be correct for the engine application.

No shutdown events should be present. If necessary, troubleshoot, correct, and reset any and all shutdown events.

PROCEDURE FOR OVERSPEED VERIFICATION

NOTE: Adjustment of ENGINE OVER SPEED SHUTDOWN THRESHOLD setpoint requires a level 3 password. For details on changing security levels refer to Chapter 6, Security.

The Security Level only affects changing parameters from the EMCP 3 GSC. Changing parameters with the Caterpillar Service Tool does not require passwords.

1. Start the engine and run the engine at rated speed.

2. Adjust the setpoint value for Engine Over Speed Shutdown Threshold to a value that is below the speed that the engine is running at. An Engine Overspeed Shutdown event will occur immediately after the setpoint is changed, and the engine will shut down.

3. View the event by going to the Genset Control event log. Reset the event. For more information about how to view and reset the event, refer to Chapter 5, Handling Events.

4. Return setpoint value for Engine Over Speed Shutdown Threshold to the original value.

PROCEDURE FOR LOW OIL PRESSURE VERIFICATION

NOTE: Low oil pressure shutdown is disabled during start-up and while the engine is not running by the Fault Protection Timer (FPT). The fault protection timer starts timing when the crank terminate RPM is reached during the starting sequence. The fault protection timer will then run for a programmed time which is determined by the Engine Start Fault Protection Activation Delay Time setpoint. Make sure the fault protection timer has elapsed before starting the Low Oil Pressure Verification.

1. Start the engine and run the engine at rated speed.

2. Adjust the setpoint value for Low Engine Oil Pressure Shutdown Event Threshold to a value that is above the oil pressure that the engine is operating at. The shutdown event will occur after the programmable time delay (the Low Engine Oil Pressure Shutdown Delay Time setpoint).

3. View the event by going to the Genset Control event log. Reset the event. For more information about how to view and reset the event, refer to Chapter 5, Handling Events.

4. Return setpoint value for Low Engine Oil Pressure Shutdown Event Threshold to the original value.

PROCEDURE FOR HIGH COOLANT TEMPERATURE VERIFICATION

NOTE: High Coolant Temperature shutdown is disabled during start-up and while the engine is not running by the Fault Protection Timer (FPT). The fault protection timer starts timing when the crank terminate RPM is reached during the starting sequence. The fault protection timer will then run for a programmed time (the Engine Start Fault Protection Activation Delay Time setpoint). Make sure the fault protection timer has elapsed before starting the High Coolant Temperature Verification.

1: Start the engine and run the engine at rated speed.

2: Adjust setpoint value for High Engine Coolant Temperature Shutdown Event Threshold to a value that is below the engine coolant temperature that the engine is operating at. The minimum value for this setpoint is 49ºC (120ºF), so you may have to run the engine for a few minutes to get the temperature above the minimum value.

The shutdown event will occur after the programmable time delay (the High Engine Coolant Temperature Shutdown Event Notification Delay Time setpoint).

3: View the event by going to the Genset Control event log.

4: Reset the event. Refer to Handling Events for more information about how to view and reset the event.

5: Return setpoint value for High Engine Coolant Temperature Shutdown Event Threshold to the original value.

4.7 ENGINE SPEED TIMING CALIBRATION - PREPARATION

The following procedure describes the required steps before an ENGINE SPEED TIMING CALIBRATION procedure is performed. After this procedure has been completed, the engine can be started and the engine can be run at rated speed.

NOTE: This procedure does NOT include the instructions for performing the actual calibration. For instructions on performing the calibration procedure, refer to the Testing and Adjusting Manual for your engine.

NOTE: Before changing any value per this procedure, RECORD THE ORIGINAL VALUE!

1: Stop the engine.

2: In the main menu scroll down until CONTROL is highlighted. Press the ENTER KEY . Scroll through the options in the control menu. If there is an option called

IDLE/RATED, go to Step 3. If not go to Step 5.

3: Make sure the IDLE/RATED option is highlighted and press ENTER KEY . If the display shows RUN AT IDLE in the IDLE/RATED screen, go to Step 10. If the display shows RUN AT RATED in the IDLE/RATED screen, go to Step 4.

4: Press the ENTER KEY and then use the UP ARROW and DOWN ARROW keys in order to select RUN AT IDLE. Press ENTER KEY to accept the new value. Go to step 10.

5: Set the ENGINE START FAULT PROTECTION ACTIVATION DELAY TIME setpoint (under Control > Auto Start/Stop) in the EMCP 3 GSC to 300 seconds.

6: If a device such as a load share module is supplying a PWM signal in order to bias the engine speed, then disconnect the PWM signal wires from the device. Go to Step 7. If there is not a device supplying a PWM signal and the engine speed bias is controlled from the EMCP 3 GSC, go to Step 9.

7: Set the PRIMARY DESIRED SPEED setpoint in the Engine ECM to PWM.

8: Set the SECONDARY DESIRED SPEED setpoint in the Engine ECM to DISABLED.

9: Start the engine and run the engine at idle speed.

10: Perform the Engine Speed Timing Calibration. See the Systems Operation, Testing and Adjusting manual for your engine for more information on how to perform the calibration procedure.

11: Stop the engine.

12: Return any modified setpoints to the original values.

13: Reconnect any wires that were disconnected in Step 6.

14: If steps 3 and 4 were performed, set the idle/rated status back to RUN AT RATED.

4.8 ENGINE OPERATING HOURS

One of the features of the EMCP 3 is the ability to maintain the ENGINE OPERATING HOURS, which is the cumulative amount of time that the engine has run above the Crank Terminate speed. This time is displayed on the Engine Overview screen, just below Battery Voltages shown in FIGURE 16.
