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.

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. Use ESD protective packaging and material handling containers that are anti-static and provide discharge protection and electric field suppression. 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: 2 SAFETY Information 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. 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.

3 INSTALLATION. 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 INSTALLATION. 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. 3 INSTALLATION 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.

For the engine harness, use the 6V Wire. Part number is available for lengths of up to 200ft. For longer runs, select a cable that meets SAE J requirements. The cable must be resistant to fuel and oil.Deutsch DT type of connectors are recommended. The Connection between the wire and the terminal should be crimped and soldered 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.

3 INSTALLATION FROM THE EMCP 3 DISPLAY Parameters are accessed (irrespective of the current screen position) by pressing the AC OVERVIEW or ENGINE OVERVIEW buttons located below the screen. Detail screens provide even more information by pressing the SCROLL DOWN overview screens.The sections below list all of the parameters available, and on which level of EMCP 3 they may be available. Parameters are displayed with units, some of which are configurable. For changing units or setting other user preferences see Chapter 4.2, Setting User Preferences. Parameters that are not available to the EMCP 3 are shown as (four asterisks). This may indicate an incorrect software configuration, a wiring problem, or a problem with the sensor. There are several preferences to alter how you view the data on the display. These include: display contrast, units used to display pressure, units used to display temperature, units used to display volume (EMCP 3.3 only), and display Only shown on the EMCP 3.3, and only if an optional Thermocouple or RTD module is connected and configured for one of these parameters. 4 INITIAL Operation and User Orientation 24 24 language (to select between the customer language and Technician English). NOTE: These preferences do not affect operation of the EMCP 3 or the data as viewed in the Caterpillar Service Tool. They only affect how the text and data is converted and displayed on the EMCP 3 GSC display. SETTING THE PREFERENCES USING THE EMCP 3 DISPLAY On the EMCP 3 display, the Preferences menu is located at the bottom of the Main Menu. The preferences are listed, with the current settings shown to the right (except language, whose current setting is usually obvious). For any preference, press ENTER KEY to accept the change (or ESCAPE KEY to reject the change) and return to the Preferences menu. PREFERENCES CONTRAST PRESSURE TEMPERATURE VOLUME (EMCP 3.3 only) LANGUAGE This determines the darkness of the pixels on the display.

A contrast setting of zero (reached by pressing and holding the down or left arrow) effectively blanks the screen, and a contrast setting of 100 (reached by pressing and holding the up or right arrow) effectively darkens the entire screen. This allows pressure parameters (such as Engine Oil Pressure) and setpoints (such as Low Engine Oil Pressure Event Threshold) to be shown in either kpa, psi, or bar. Select the desired unit with the left or right arrows. This allows temperature parameters (such as Engine Coolant Temperature) and setpoints (such High Engine Coolant Temperature Event Threshold) to be shown in either Celsius (Centigrade) or degrees Fahrenheit. This allows volume parameters (such as Fuel Volume) to be shown in either Liters, Imperial Gallons, or US Gallons. This allows the display to be switched between Technician English (always listed first) and the customer language (always listed second, and written in the font of the customer language). The below example shows the language selection in the German language flash file. The LANGUAGE setting has been conveniently located at the bottom of the Preferences menu, which is at the bottom of the Main Menu. If an EMCP 3 which is set to display an unknown language, the following steps will change the language to Technician English, regardless of the current screen, and without needing to read the text. 4 INITIAL Operation and User Orientation 25 25 CHANGING TO TECHNICIAN ENGLISH Press the ENGINE OVERVIEW key Press the ESCAPE KEY (this will take you to the top of the Main Menu) SCROLL DOWN until the scrolling stops Press the ENTER KEY (this will take you into the Preferences Menu) SCROLL DOWN until the scrolling stops Press the ENTER KEY (this will take you into the language selection) Press the ENTER KEY to select TECHNICIAN ENGLISH (shows as TECH ENGLISH on the EMCP 3.1 or 3.2) The EMCP 3 language setting is changed back to TECHNICIAN ENGLISH.

Select Display Preferences from the left pane. 4 INITIAL Operation and User Orientation 26 26 FIGURE 13: DISPLAY PREFERENCES The display units can be changed the same way other setpoints are changed with the Service Tool. PRESSURE This allows pressure parameters (such as Engine Oil Pressure) and setpoints (such as Low Engine Oil Pressure Event Threshold) to be shown in either kpa, psi, or bar. TEMPERATURE VOLUME This allows temperature parameters (such as Engine Coolant Temperature) and setpoints (such High Engine Coolant Temperature Event Threshold) to be shown in either Celsius (Centigrade) or degrees Fahrenheit. 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. 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.

Refer to Chapter 6, Security for information on obtaining LEVEL 1 ACCESS. Press the RIGHT ARROW key to put the box around the date ENTER KEY. Press ENTER KEY again to begin editing the date. Use the LEFT ARROW or RIGHT ARROW keys to select a digit and the UP ARROW or DOWN ARROW keys to change it. Press ENTER KEY to accept, or ESCAPE KEY to reject, your change. 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. If the EMCP 3 GSC is not programmed for an electronic engine, speed will not show up as an option. The speed and voltage adjust screen will be displayed. To adjust the engine speed from this screen To INCREASE the engine speed 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. To adjust the generator output voltage from this screen To INCREASE the generator output voltage. To DECREASE the generator output voltage. 4 INITIAL Operation and User Orientation 30 30 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. To change the state, Press UP ARROW ARROW Press ENTER KEY or DOWN Then select the value. 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.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). 4 INITIAL Operation and User Orientation 31 31 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. 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. 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. 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.If the ENTER KEY bypassed. 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 4 INITIAL Operation and User Orientation 33 33 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. 4 INITIAL Operation and User Orientation 34 34 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 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 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.
