            General information

            1

            Introduction

            The 2300 and 2800 Series industrial diesel engines are the latest development from Perkins Engines

            Company Limited, a world leader in the design and manufacture of high performance diesel engines.

            Read and remember the "Safety precautions" on page 2. They are given for your protection and must be

            applied at all times.

            Danger is indicated in the text by two methods:

            Warning! This indicates that there is a possible danger to the person.

            Caution: This indicates that there is a possible danger to the engine.

            Note: Is used where the information is important, but there is not a danger.

            Ensure that all adjustments and repairs are done by personnel who have had the correct training.

            1

            2300 Series

            Safety precautions

            These safety precautions are important. Reference must also be made to the local regulations in the country

            of operation.

            Only use these engines in the type of application for which they have been designed.

            Do not change the specification of the engine.

            Do not smoke when you put fuel in the tank.

            Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a

            safe place.

            Do not put fuel in the tank while the engine runs (unless it is absolutely necessary).

            Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct training;

            even then extreme caution must be used to prevent injury).

            Do not make adjustments that you do not understand.

            Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.

            Other persons must be kept at a safe distance while the engine or equipment is in operation.

            Do not permit loose clothing or long hair near moving parts.

            Keep away from moving parts during engine operation.

            Warning! Some moving parts cannot be seen clearly while the engine runs.

            Do not operate the engine if a safety guard has been removed.

            Do not remove the filler cap of the cooling system while the engine is hot and while the coolant is under

            pressure, because dangerous hot coolant can be discharged.

            Do not use salt water or any other coolant which can cause corrosion in the closed coolant circuit.

            Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the

            gases from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially

            to the eyes.

            Disconnect the battery terminals before a repair is made to the electrical system. Always disconnect the

            negative terminal first.

            Only one person must control the engine.

            Ensure that the engine is operated only from the control panel or from the operator’s position.

            If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.

            Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.

            Protect your hands with gloves or a special solution to protect the skin.

            Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated

            with oil into the pockets.

            Discard used lubricating oil in a safe place to prevent contamination.

            The combustible material of some components of the engine (for example certain seals) can become

            extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with

            the eyes.

            Fuel and oil pipes MUST be inspected for cracks or damage before they are fitted to the engine.

            Fit only genuine Perkins parts.

            1

            2300 Series

            Glossary of terms

            Active diagnostic code

            Describes a condition that is currently present to alert the operator or service technician of an abnormal engine

            operation parameter. See also Diagnostic fault code.

            Aftermarket device

            A device or an accessory that is installed by the customer or OEM after the engine has been delivered.

            Alternating current (AC)

            The direction of current flow changes (alternates) regularly and constantly in a circuit.

            Atmospheric pressure sensor

            Analogue sensor generates a signal proportional to atmospheric (barometric) air pressure in the crankcase

            and sends a signal to the ECM.

            Before top center (BTC)

            The 180° of crankshaft rotation before the piston reaches the very top of its travel (normal direction of rotation).

            Intake manifold pressure sensor

            This sensor measures inlet manifold air pressure (boost pressure) and sends a signal to the ECM.

            Bypass circuit

            A circuit, usually temporary, to substitute for an existing circuit, typically for test purposes.

            Calibration

            An electronic adjustment of a sensor signal.

            Electronic system overview

            2

            System operation

            The 2300 and 2800 Series industrial diesel engines are designed for electronic control. The injection pump,

            fuel lines and nozzles used in mechanical engines have been replaced with an electronic unit injector in each

            cylinder. A solenoid on each injector controls the amount of fuel that is delivered by the injector. An Engine

            Control Module (ECM) sends a signal to each injector solenoid in order to provide complete control of the

            engine.

            Electronic controls

            The electronic system consists of the Engine Control Module (ECM), the engine sensors and the OEM

            interface. The ECM is the computer which controls the engine and contains the software which controls how

            the ECM behaves and stores the operating maps that define power, rev/min, etc.

            Engine governor

            The electronic controls on the engine serve as the engine governor, determining when and how much fuel to

            deliver to the cylinders based on the actual and desired conditions at any given time.

            The ECM uses one of three possible speed control inputs to determine the desired engine speed and

            compares this to the actual engine speed determined through the crankshaft position sensor. If the desired

            engine speed is greater than the actual engine speed, more fuel is injected in order to increase engine speed.

            Timing considerations

            Once the ECM has determined how much fuel is required, it must next determine when to inject the fuel.

            Injection timing is determined by the ECM after considering input from the following components:

            Coolant temperature sensor

            Intake manifold air temperature sensor

            Atmospheric pressure sensor

            Intake manifold pressure sensor

            The ECM determines where top centre on cylinder number one is located from the engine camshaft position

            sensor signal. The ECM decides when injection should occur relative to top centre and provides the signal to

            the injector at the desired time. The ECM adjusts timing for the best engine performance, fuel economy and

            white smoke control.

            Note: Actual or desired timing cannot be viewed with the TIPSS-EST service tool.

            2

            2300 Series

            Fuel injection

            The ECM controls the amount of fuel injected by varying the signals to the injectors. The injectors will pump

            fuel only if the injector solenoid is energized. The ECM sends a high voltage signal to energize the solenoid.

            By controlling the timing and duration of the high voltage signal the ECM can control injection timing and the

            amount of fuel that is injected.

            The software inside the ECM sets certain limits on the amount of fuel that can be injected. The fuel limit is a

            limit based on boost pressure to control the air/fuel ratio for control of emissions. When the ECM senses a

            higher boost pressure (more air into cylinder) it increases the fuel limit (allows more fuel into cylinder).

            The Rated Fuel Limit is a limit that is based on the power rating of the engine and engine rev/min. It is similar

            to the rack stops and torque spring on a mechanically governed engine. It provides power and torque curves

            for a specific engine family and rating.

            Note: All of these limits are determined at the factory in the ECM software and cannot be changed.

            2300 Series

            Engine monitoring

            Perkins provides a factory installed engine monitoring system. The Perkins engine monitoring system monitors

            the following parameters:

            Engine oil pressure

            Coolant temperature

            Intake manifold air temperature

            Engine speed

            Boost pressure

            Fuel temperature

            The Perkins engine monitoring system has three levels of operation, WARNING, ACTION ALERT and

            SHUTDOWN as described below.

            Perkins engine monitoring WARNING operation

            In the WARNING condition the ECM causes the Warning lamp to turn ON to indicate a problem has been

            detected by the Engine Monitoring System. No further ECM or engine action occurs.

            Perkins engine monitoring ACTION ALERT operation

            In the ACTION ALERT condition the ECM begins by activating the Action Alert lamp ON to indicate a problem

            has been detected by the Engine Monitoring System. This is also normally wired to cause a shutdown via the

            OEM control panel.

            Perkins engine monitoring SHUTDOWN operation

            If the fault reaches the SHUTDOWN condition the ECM activates the shutdown lamp and unless the engine is

            in CRITICAL OVERRIDE condition, the engine will shutdown.

            Fuel temperature monitoring

            The fuel temperature sensor monitors the fuel temperature, adjusting the ECM calculated fuel rate to

            compensate for fuel temperature changes and to adjust the fuel rate for constant power. The sensor is also

            used to warn the operator of excessive fuel temperature with a diagnostic event code because excessive fuel

            temperatures can adversely affect engine performance.

            Self diagnostics

            The electronic system has the ability to diagnose problems. When a problem is detected, a diagnostic code is

            generated and stored in permanent memory (logged) in the ECM. The diagnostic lamp is also activated.

            When diagnostic codes occur, the diagnostic codes are referred to as Active diagnostic codes. They indicate

            that a problem of some kind currently exists.

            Diagnostic codes that are stored in memory are called Logged diagnostic codes. Since the problem may have

            been temporary, or may have been repaired since the problem was logged, logged codes do not necessarily

            mean that something needs to be repaired. They are instead meant to be an indication of probable causes for

            intermittent problems.

            Diagnostic codes that identify operating conditions outside the normal operating range are called Events.

            Event codes are not typically an indication of an electronic system problem.

            Note: Some of the diagnostic codes require passwords to clear.

            Effect of diagnostic codes on engine performance

            The discussion on engine monitoring mentions that the diagnostic lamp activates when a specific condition

            exists. When the ECM detects an engine problem, it generates an active diagnostic code and also logs the

            diagnostic code in order to indicate when, and if appropriate, how many times the problem occurred. There are

            two types of diagnostic codes, Fault codes and Event codes.

            Diagnostic fault codes

            These are provided in order to indicate that an electrical or electronic problem has been detected by the ECM.

            In some cases the engine performance can be affected when the condition causing the code exists. More

            frequently, however, no difference in the engine performance can be detected.

            Diagnostic event codes

            Diagnostic event codes are used to indicate that some operational problem has been detected in the engine

            by the ECM. This usually does not indicate an electronic malfunction.

            The ECM also provides an ECM clock with date/time to date and time stamp the following critical event codes:

            360-3 Low oil pressure Shutdown

            361-3 High coolant temperature Shutdown

            For a listing all of the diagnostic fault codes, along with the page number where details regarding the cause,

            performance effect, and diagnosis of the code can be located, refer to "Diagnostic code quick reference" on

            page 80.

            Current totals stored in the ECM

            The ECM maintains engine total data for the following parameters:

            Total time

            The total time is the engine's operating hours. This does not include operating time when the ECM is powered

            ON but the engine is not running.

            Programmable parameters

            Certain parameters affecting engine operation may be changed with the TIPSS-EST service tool. The

            parameters are stored in the ECM, and are protected from unauthorized changes by passwords. These

            parameters are either system configuration parameters or customer parameters.

            System configuration parameters

            These are set at the factory and affect emissions or power ratings within an engine family. Factory passwords

            must be obtained and used to change the system configuration parameters.

            Customer parameters

            These are variable and can be used to tailor the engine to customer requirements within the limits set by the

            factory and Perkins engine monitoring operation. Customer passwords may be required to change customer

            parameters.

            Caution: Some of the parameters may affect engine operation. Without adequate training, these parameters

            may lead to power or performance complaints even when the engine is performing to specification.

            Refer to "Programming parameters" on page 29 for further information.

            Service tools and diagnostics

            The Perkins TIPSS-EST service tool is designed to help the service technician analyse and locate faults or

            problems within the system. They are required to perform calibrations and to read or change engine

            parameters.

            Perkins TIPSS-EST is a software program that runs on a personal computer and requires a communication

            adapter to translate information from the Perkins Data Link to the computer RS232 port.

            Perkins TIPSS-EST can be used to display the following information:

            Programmable parameter settings

            Active and logged diagnostic codes

            Logged events

            Engine rating history

            Histograms

            Custom data

            ECM date/time clock

            Perkins TIPSS-EST can also be used to perform the following functions:

            Diagnostic tests

            Sensor calibrations

            Flash programming

            Parameter programming

            Copy configuration (ECM replacement)

            Data logging

            Real time graphing

            There are several adapter cables, breakout T cables, etc that are used in order to access measurements of

            signals. A heavy duty multimeter is suitable in order to make the necessary measurements. A multimeter that

            has the ability to measure duty cycle may also be required. Other special tools include those needed to

            measure pressure and temperature. For further details refer to Chapter 5, Special tools.

            A diagnostic code reader is also available. This is a hand held unit which allows reading certain parameters

            and diagnostic codes.

            Connecting the TIPSS-EST

            The communications adapter is powered by 24 Volts DC from the engine battery. This permits operation

            beside the engine to allow use during engine operation.

            Use the following procedures to connect the service tool to the engine.

            1  Stop the engine by turning the key switch to the OFF position.

            2  Connect the service tool harness cable on the engine to the communication adapter. Refer "Connecting

            TIPSS-EST using a TIPSS communication adapter" on page 22.

            3  Connect the communication adapter to the PC using the appropriate cable.

            4  Turn the key switch to the ON position in order to begin testing. The service tool will operate while the engine

            is running or with the engine OFF and the key switch ON. If the tool does not communicate with the ECM

            disconnect and reconnect the diagnostics connector cable. Check the communication. If the problem is still

            present refer to Test 45: Perkins Data Link circuit test on page 118.

            Notes:

            The service tool may restart during engine cranking due to a voltage dip on the battery line.

            The TIPSS-EST must be configured to communicate with the specific type of communication adapter used.

            Go to the "Preferences" menu that is located under "Utilities" in order to select the appropriate

            communication adapter.

            Passwords

            Factory passwords

            Factory passwords are required to perform each of the following functions:

            1  Program a new ECM

            When an ECM is replaced the system configuration parameters must be programmed into the new ECM. A

            new ECM will allow these parameters to be programmed once without factory passwords. After the initial

            programming these parameters are protected by factory passwords.

            2  Rerate to another engine family

            This requires changing the ECM software code, which is protected by factory passwords.

            3  Read customer passwords

            If the owner loses his customer passwords, he will not be able to program customer parameters. By using

            factory passwords, one can read customer passwords, then use those customer passwords to program

            customer parameters.

            4  Clear certain diagnostic codes

            Diagnostic code 253-02 Incorrect ECM software requires a factory password to clear the code. This diagnostic

            code should be cleared only if you are certain that the ECM software is for the specific engine.

            Caution: Operating the engine with ECM software not designed for that engine will result in engine damage.

            Be sure the ECM software is correct for your engine.

            5  Certain other codes require customer passwords. The majority of logged codes do not require passwords

            to be cleared. To obtain factory passwords, proceed as if you already have the password. At some point, if the

            factory passwords are actually needed, TIPSS-EST will request the factory passwords and display the

            information required to obtain the passwords.

            Customer passwords

            If customer passwords have been entered, they are then required to change ANY customer parameter.

            TIPSS-EST can be used to change customer parameters. To obtain customer passwords, contact the supplier

            of the equipment. If the owner has lost the passwords, customer passwords may be read by using TIPSS-EST

            (factory passwords are required in order to read customer passwords) by using the following procedure.

            1  In TIPSS-EST access "Passwords" under the "Information" menu.

            2  When the "Factory Password" screen appears, record the information listed.

            3  Obtain the factory passwords. The information recorded above must be provided, and generates a

            permanent record at Perkins of the access.

            4  From the "Factory Password" screen, enter the factory passwords.

            5  When the "View Customer Passwords" screen appears, record the customer passwords. The customer

            passwords may then be used to change customer parameters.

            Programming a new ECM

            The Engine Control Module or ECM is the brain of the system. When a problem occurs, it is easy to assume

            that the ECM is responsible. This is usually the wrong conclusion.

            Most failures occur at the wiring and connectors or at a sensor input/output. Follow the diagnostic test

            procedures and do not replace an ECM on speculation.

            However, when your diagnosis indicates that a failure has in fact occurred in the ECM, the following procedure

            outlines the steps required to replace a faulty ECM.

            Note: If an ECM replacement is required, the ECM parameters and injector trim codes can be transferred from

            the suspect ECM to the replacement ECM. This feature requires TIPSS-EST and is only possible if the suspect

            ECM can communicate with the TIPSS-EST.

            Replacing the ECM using TIPSS-EST ECM replacement feature

            Note: The Test ECM referred to below is another identical ECM to that fitted to the engine. There is no special

            Test ECM available.

            1  Ensure that the ECM is the problem by first temporarily connecting a test ECM. Hang the test ECM on the

            side of the engine. Flash program the identical software that was used in the suspect ECM into the test ECM.

            Use the TIPSS-EST ECM replacement feature to copy the parameter configuration of the suspect ECM into

            the test ECM. Ensure that the parameters in the test ECM are programmed the same as the parameters in the

            suspect one.

            2  If the test ECM repairs the problem, reconnect the suspect ECM. Check that the problem returns when the

            suspect ECM is reconnected.

            3  Select the ECM Replacement feature under the "Service/Copy Configuration" menu and load the

            parameters from the failed ECM.

            4  Temporarily connect the new ECM by connecting both ECM connectors. Do not mount the ECM on the

            engine yet.

            5  Flash program the ECM software into the new ECM if the software is not already installed.

            Note: The new ECM may be shipped with no software installed or may have been pre-flashed at the factory.

            Following reflashing the engine may be inoperable until a factory password has been obtained.

            6  Use the TIPSS-EST ECM replacement feature to program the new ECM

            7  Enter rating number parameter into the new ECM

            8  Check for active codes. Program any required parameters that have not been programmed.

            Note: On initial power-up of a new ECM, the Rating Number parameter must be programmed to avoid a

            268-02 Check Programmable Parameters diagnostic code.

            Install the new ECM on the engine and after checking for correct operation perform a timing calibration.

            2300 Series

            Replacing the ECM (if ECM replacement feature cannot be used)

            1  Ensure that the ECM is the problem by first temporarily connecting a test ECM. Hang the test ECM on the

            side of the engine. Flash program the identical software that was used in the suspect ECM into the test ECM.

            Program any parameters that are necessary to use the ECM for the test. Program the parameters exactly the

            same as they are in the suspect ECM.

            2  If the test ECM repairs the problem, reconnect the suspect ECM. Check that the problem returns when the

            suspect ECM is reconnected.

            3  Obtain customer parameters from the failed ECM

            Obtain and record the customer passwords. If the customer has lost or forgotten their passwords, obtain

            factory passwords to get them.

            Use TIPSS-EST to access customer specified parameters from the ECM that is being replaced. If the ECM

            does not communicate with the electronic service tool, obtain the required parameter list from the OEM.

            Record the customer parameters.

            4  Record ECM current totals

            5  Temporarily connect the new ECM by connecting both ECM connectors. Do not mount the ECM to the

            engine until the timing calibration has been performed.

            6  Flash program the software into the new ECM if the software is not already installed.

            Note: The new ECM may be shipped with no software installed, or may have been pre-flashed at the factory.

            7  Obtain factory passwords if required. The following parameters can be programmed once on a new ECM

            without factory passwords:

            Full Load Setting (FLS)

            Full Torque Setting (FTS)

            Engine serial number

            System configuration parameters must be entered before the customer specified parameters are entered

            If customer parameters are entered before the system configuration parameters, the total tattletale will change.

            It will then be necessary to obtain another set of factory passwords in order to access system configuration

            parameters.

            8  Record the following information from the engine information plate:

            Engine serial number

            Obtain the following information from the factory:

            Full Load Setting (FLS)

            Full Torque Setting (FTS)

            Injector Trim Codes

            Use TIPSS-EST to access system configuration parameters. When the "Factory Specified Passwords" screen

            appears record the following information:

            ECM serial number

            Engine serial number

            TIPSS-EST serial number

            Total tattletale

            Reason code

            Leave TIPSS-EST on the "Factory Specified Passwords" screen and obtain the factory passwords.

            On initial powerup of a new ECM the following three parameters must be programmed to avoid a 268-02

            Check Programmable Parameters diagnostic code:

            Full Load Setting (FLS)

            Full Torque Setting (FTS)

            Engine serial number

            Use TIPSS-EST to access system configuration parameters. Enter the recorded values for the following

            parameters:

            Full Load Setting (FLS)

            Full Torque Setting (FTS)

            Engine serial number

            Injector trim codes

            Use TIPSS-EST to access customer specified parameters. Enter the customer specified parameters and the

            original customer passwords.

            Use TIPSS-EST to access current totals from the "Read/Change Current Totals" main menu. Using the

            recorded factory passwords enter the totals from the original ECM.

            Use the "Service\Calibrations\Timing Calibration" menu to calibrate the timing. Refer to Test 46: Engine

            Programming an ECM using flash programming

            1  Connect the PC to the appropriate communication adapter and connect the communication adapter to the

            ECM. Refer to "Connecting TIPSS-EST using a TIPSS communication adapter" on page 22.

            2  Start the WinFlash PC Program.

            3  Ensure that the key switch is ON and the engine is OFF.

            4  Select the part number of the engine software that needs to be programmed into the ECM and proceed with

            programming. A new ECM is shipped with no software loaded.

            Note: The WinFlash PC program provides the ECM, application and software part number of the selected file.

            Ensure that this file matches the engine before you begin to Flash the file into the ECM

            PC program software messages and their meaning

            A new ECM comes unprogrammed. An unprogrammed ECM will prompt you for all three of the following

            messages. The information that is contained in the ECM Status will be scrambled and meaningless if the

            module has not been programmed previously (this is normal).

            Message: The engine ID in the flash file does not match the engine ID in the ECM

            Meaning: The ECM has software for a different engine.

            Solution: Stop the transfer and access information about the ECM Status under the "Electronic Control

            Module" menu. Ensure that the file you are about to transfer matches the engine application.

            Message: The application ID in the flash file does not match the application ID in the ECM

            Meaning: The ECM has software for a different application.

            Solution: Stop the transfer and access information about the ECM Status under the "Electronic Control

            Module" menu. Ensure that the file you are about to transfer is for the correct engine type.

            Message: The ID of the ECM in the flash file does not match the ID of the ECM in the ECM

            Meaning: The ECM is not for use with this application.

            Solution: Stop the transfer and access information about the ECM status under the "Electronic Control

            Module" menu. Ensure that the ECM on the engine is for the correct application.

            Note: If you access the ECM status under the "Engine Control Module" menu, but do not program the ECM,

            complete the following procedure.

            Turn the key switch to the OFF position, and then to the ON position before using TIPSS-EST. If the key switch

            is not cycled after reading the ECM Status, the ECM will not communicate with your service tool or will not start.

            Cycling the key switch is not necessary after the software has been successfully programmed using the

            WinFlash program.

            5  Start the engine and check for correct operation.

            Program any parameters not previously in the old software if a 268-02 Check Programmable Parameters

            diagnostic code is active. Read the diagnostic code from service tool "Active Diagnostic Code" screen in order

            to determine the parameter(s) requiring programming.

            On initial powerup of a new ECM three parameters must be programmed to avoid a 268-02 Check

            Programmable Parameters diagnostic code:

            Full Load Setting (FLS)

            Full Torque Setting (FTS)

            ECM date/time clock

            ECM date/time stamped information

            The ECM date and time can be programmed with the TIPSS-EST service tool (factory passwords are required

            to change these parameters). This will display the programmed date in month/day/year format and the

            programmed time in hour:minute:second format. The tool has the option to program any date/time or

            automatically select the date/time stored in the PC real time clock.

            The date and time will remain programmed in the ECM even if the unswitched battery connections are

            removed.

            The ECM Date/time clock is used to stamp the following critical event codes:

            360-3 Low oil pressure Shutdown

            361-3 High coolant temperature Shutdown

            Before adjusting the ECM date/time clock

            Before adjusting the ECM date/time clock, ask the owner/operator if the time stamped information should be

            recorded. After the time stamped information is recorded, clear this information before adjusting the ECM date/

            time clock. This is a very important step if the adjustment of the clock is a big adjustment. This will prevent

            unnecessary confusion if someone else views the information at a later date.

            Determining time stamped information occurrence

            When viewing time stamped information remember that someone may have incorrectly or never set the clock.

            Use the time currently set in the ECM to compare any ECM recorded information to the time the ECM indicates

            to determine how long ago the time stamped event occurred.

            Caution: Do not replace an ECM because of an incorrect time.

            The following example indicates the correct use of the clock.

            Example use of ECM date/time stamped information

            The TIPSS-EST service tool indicates a Low Oil Pressure occurred on NOV 19 1998 10:30:46 and that the

            current time of day in the ECM is NOV 24 1998 11:20:58.

            This indicates that the problem occurred approximately 5 days and 50 minutes ago.

            Caution: Do not compare it to the current time at your location.

            If the ECM time is significantly different than your current time, for example the wrong month is programmed,

            ensure you have recorded the time stamped information if it is important. After recording the information, clear

            the code and then adjust the clock.

            ECM diagnostic clock

            The diagnostic clock should not be confused with the ECM date/time clock. The diagnostic clock records the

            actual hours the ECM has been powered (key switch ON and engine running). This information is maintained

            even if the unswitched battery connections are removed. The clock information is used to log diagnostic code

            and event code occurrences. Logged diagnostic codes and event codes display the diagnostic clock hour of

            the first and last occurrence and the total number of occurrences.

            Note: Actual engine running hours (total time) can be obtained from the "Current Totals" menu of TIPSS-EST.

            Injector codes

            Injector codes are etched on each injector. The injector codes can be viewed/changed using TIPSS-EST by

            selecting the "Calibrations" screen under the "Service" menu. The injector codes calibration is located under

            the "Calibration" menu. The injector code must match the code on the corresponding injector. When an injector

            is replaced, reprogram the new code for the new injector.

            TIPSS-EST cylinder cut-out test

            The 2300 and 2800 Series engines use electronic fuel injectors. These injectors are mechanically actuated

            and electronically energized. The cylinder cut-out tests are used to confirm that the cylinders are functioning

            correctly.

            The cylinder cut-out test allows a specific cylinder to be cut out while the fuel position is monitored for the

            remaining cylinders.

            To perform a cylinder cut-out test, connect TIPSS-EST to the diagnostic connector as described in

            "Connecting the TIPSS-EST" on page 21, and select the Cylinder cut-out test located under the "Diagnostics"

            menu.

            The Cylinder cut-out test opens with the manual test. At the bottom of the TIPSS-EST screen there is a row of

            buttons that function as follows:

            Change toggles the highlighted cylinder between powered and not powered

            Power All returns all cylinders to the normal operating state

            Start initiates the automated Cylinder cut-out test.

            Stop terminates the automated test.

            Results displays the test results.

            Print allows the contents of the screen to be previewed or to be sent to a file or printer.

            Programming parameters

            Many programmable parameters affect engine operation. These parameters may be changed by using the

            TIPSS-EST service tool. The parameters are stored in the ECM. Whilst any parameter can be read, passwords

            can be used to protect parameters from unauthorized changes.

            Two categories contain these various parameters:

            System configuration parameters

            System configuration parameters can only be altered with factory passwords by using TIPSS-EST.

            Customer specified parameters

            Customer specified parameters can be changed by using the TIPSS-EST service tool (this may require

            customer passwords if customer passwords have been programmed). Refer to "Passwords" on page 13 for

            more details on how to receive and use factory and customer passwords.

            System configuration parameters

            System configuration parameters affect critical settings for the engine. They are programmed at the factory

            and would normally never need to be changed through the life of the engine. A complete list of these

            parameters is given in the table on the following page.

            Note: System Configuration Parameters must be reprogrammed if an ECM is replaced. Failure to programme

            these parameters will result in a 268-02 Check Programmable Parameters diagnostic code.

            Proper values for these parameters are stamped on the engine information ratings plate located on the valve

            cover or air inlet manifold. Factory passwords are required to change these parameters. The following

            information is a description of the system configuration parameters.

            Full Load Setting (FLS)

            Number representing fuel system adjustment made at the factory to “fine tune” the fuel system. The correct

            value for this parameter is stamped on the engine information ratings plate. A new ECM requires this

            parameter to be programmed to avoid generating a 268-02 Check Programmable Parameters diagnostic code.

            Full Torque Setting (FTS)

            Similar to Full Load Setting. This parameter must be programmed to avoid generating a 268-02 Check

            Programmable Parameters diagnostic code.

            Software part number

            This is the part number of the software flashed into the ECM.

            Engine serial number

            This should be programmed to match the engine serial number that is stamped on the engine information plate.

            A new ECM is delivered without the engine serial number programmed.

            ECM serial number

            This is a read-only parameter which displays the serial number of the ECM.

            Software release date

            This parameter is defined by the ECM software and is not programmable. It is used to provide the version of

            the software. Customer parameters software changes can be tracked by this date. The date is provided in the

            month and year (NOV99), where NOV is the month (November) and 99 is the year (1999).

            Critical override switch installed

            The critical override switch, if fitted and enabled, allows the engine to continue running even if engine oil

            pressure or coolant temperature have reached the limits where the engine would normally be shutdown. If the

            engine is run in this condition, the engine warranty is void and any events occurring are stored in the ECM with

            time and date stamping. Implementation of this facility requires a factory password.

            Total tattletale

            Displays the total number of times the configuration parameters have been changed.

            Customer specified parameters

            Customer specified parameters allow the OEM to modify engine parameters to suit the application.

            Customer parameters may be changed repeatedly as a customer changes his requirements. Customer

            passwords are required to change these parameters.

            The following information is a brief description of the customer specified parameters.

            Rating duty selection

            This enables selection of the engine rating from a series of maps within the ECM. Changing the rating requires

            a customer password. The available ratings within the ECM will vary with engine type and specification.

            Rated frequency

            This displays the rated frequency of the set, i.e. 50 Hz or 60 Hz, determined by the rating selection and the

            status of the external speed selection switch. This parameter is read only.

            Rated speed

            This displays the rated speed of the engine, i.e. 1500 rev/min or 1800 rev/min, determined by the rating

            selection and the status of the external speed selection switch. This parameter is read only.

            Rated real genset power

            This displays the maximum power in kW of the currently selected rating. This parameter is read only.

            Rated apparent genset power

            This displays the maximum power in kVA of the currently selected rating. This parameter is read only.

            Rating configuration

            This displays the configuration of the currently selected rating. The possible configurations are:

            Standby power

            Limited time prime power

            Prime power

            Continuous or baseload power

            For definitions of these ratings, refer to ISO8528. This parameter is read only.

            Note: Not all of the above rating configurations will be available in a given ECM software file.

            External speed selection switch enable

            For dual speed (1500 rev/min or 1800 rev/min) applications, where an external speed selection switch is

            required, this parameter enables the functionality of the speed selection switch within the software. Changing

            this parameter requires a customer password.

            Engine startup acceleration rate

            Enables the acceleration rate of the engine in rev/min/s, from idle speed to rated speed, to be programmed.

            Control of this parameter enables any overshoot in speed on start up to be limited. Changing this parameter

            requires a customer password.

            Droop/isochronous switch enable

            Determines whether the external droop/isochronous switch is enabled or disabled. Changing this parameter

            requires a customer password.

            Droop/isochronous selection

            The engine will normally be run in isochronous mode i.e. the engine speed is the same at all loads. For certain

            applications where parallel operation with another generating set or with the grid is required, it is necessary for

            stability reasons to run in droop condition where engine speed drops with load. This parameter enables droop/

            isochronous running selection. Changing this parameter requires a customer password.

            Note:  , If an external droop/isochronous switch is enabled, the position of this switch will over-ride the Droop/

            Isochronous selection.

            2300 Series

            Engine speed droop

            If droop operation is selected, this parameter allows the setting of percentage droop i.e. the percentage that

            the engine speed will drop with load. This parameter has no effect when the engine is running in isochronous

            mode. Changing this parameter requires a customer password.

            Digital speed control installed

            This parameter determines whether raise/lower switch input control of engine speed is installed. If digital speed

            control is not installed, speed control reverts to the analogue or PWM inputs depending on which input is

            selected via the desired speed input configuration detailed on the following page. Changing this parameter

            requires a customer password.

            Digital speed control min speed

            This setting determines the minimum speed range of both the raise/lower button control and the analogue

            control, for example: if this is set to 100 rev/min and the nominal engine speed is selected for 1500 rev/min,

            the minimum speed setting is 1400 rev/min. It does not affect the PWM speed control range which has fixed

            min/max limits. Changing this parameter requires a customer password.

            Digital speed control max speed

            This setting determines the maximum speed range of both the raise/lower button control and the analogue

            control, i.e. if this is set to 100 rev/min and the nominal engine speed is selected for 1500 rev/min, the

            maximum speed setting is 1600 rev/min. It does not affect the PWM speed control range which has fixed min/

            max limits. Changing this parameter requires a customer password.

            Digital speed control ramp rate

            This setting determines the rate of change of engine speed in rev/min/s when the raise/lower switch inputs are

            closed. Changing this parameter requires a customer password.

            Crank terminate speed

            This parameter is used to set the engine speed at which the crank terminate relay output will be switched.

            Changing this parameter requires a customer password.

            Desired speed input arrangement

            This parameter allows selection of the analogue or PWM external speed control if the digital speed control is

            not installed. The Analogue or PWM speed control inputs are normally used with generating set load sharing

            and synchronising controllers. Changing this parameter requires a customer password.

            Note:  If PWM or Analogue speed control is selected but there are no inputs to the selected speed control

            terminals, the engine will default to running at 1100 rev/min.

            If it is not intended to use PWM or analogue speed control then the Digital speed control should be selected.

            Governor gain parameters

            The adjustable Governor Gain parameters are:

            Governor Gain Factor

            Governor Minimum Stability Factor

            Governor Maximum Stability

            Notes:

            No engineering units associated with these numbers.

            The programmable range is wide for flexibility. The values are valid from 1- 40000. This wide programmable

            range may not be fully used on any system. Do not expect to use the whole range.

            Gain explanations

            Governor gain factor

            The governor gain factor is multiplied to the difference between desired speed and actual speed.

            If the governor gain factor value is too large, the engine speed can overshoot the desired speed. The

            overshoot is caused by an overcorrection or a steady state instability.

            If the governor gain factor is too small, the response necessary to accelerate the engine to the desired

            speed must be obtained by ramping the stability terms to a higher value. This process is time consuming

            so, as a result, the engine speed is slow to respond.

            Governor minimum/maximum stability factor

            The stability factor terms work to eliminate a steady state speed error. There are two gain terms used for

            stability. If the error is greater than 20 rev/min and the error is increasing, then the maximum stability gain is

            functioning. If the error is less than 20 rev/min, then the minimum stability gain is used. This function allows

            the use of a high gain that would otherwise cause the engine to be unstable when the engine is operating near

            the desired speed.

            If either the minimum stability gain or the maximum stability gain is set too high, the governor will provide

            more fuel than is necessary to bring the error to zero. The additional fuel will cause the engine speed to

            overshoot and ring.

            If either the minimum stability gain or the maximum stability gain is set too low, the engine will take too long

            to arrive at a steady state speed.

            Tuning procedure

            1  Turn the key switch to the OFF/RESET position. Connect the TIPSS-EST service tool and check that engine

            overspeed protection is enabled before beginning the tuning process. Engine overspeed is configured on the

            "Service\Monitoring System" screen on TIPSS-EST.

            Warning! Performing engine governor tuning without engine overspeed protection could result in serious

            engine damage. Ensure that this parameter is ON while performing this procedure.

            2  Start the engine. Observe, on the engine mounted genset control panel, that the engine has reached rated

            speed. This panel will serve as the speed reference point during this procedure.

            3  Enter the "Configuration Parameters" screen on TIPSS-EST.

            4  Determine the desired scenario to tune the engine. For example, is the engine having poor response during

            specific load assignments or specific load dumps ?

            5  Perform the desired load change from step 4. Observe the response of the engine by viewing the engine

            speed on the genset mounted control panel, by looking at the system bus frequency response to the load

            change, or by listening to the response of the engine.

            6  Use the suggestions listed above to determine which gains should be adjusted.

            Note: Usually, the governor gain factor should be somewhat lower that the governor minimum stability factor

            for optimum performance. The maximum stability factor is typically a smaller value than the minimum stability

            gain and governor gain factor.

            7  Repeat steps 5,6, and 7 until a desired engine response can be met. Use large adjustments (10% of original

            gain) at first to generally tune the engine in the proper manner. As the response is closer to desired, increase

            the gains in smaller increments (1% of total gain).

            Customer password 1, customer password 2

            These are the customer password programmable parameters that can be used to protect certain configuration

            parameters from unauthorised changes.

            Fault diagnosis

            4

            Introduction

            This chapter has information that will assist with the diagnosis of mechanical and electronic faults on the

            engine, and its management system.

            The diagnostic process

            Some engine symptoms are caused by conditions or components other than the electronic control system,

            such as poor fuel quality or incorrectly adjusted valves.

            The basic philosophy of diagnosing this engine is to follow the three steps listed below FIRST to diagnose a

            malfunctioning engine:

            1  Gather operator information. Check that the fault is not due to normal engine operation.

            2  Perform a visual inspection of the engine. Check fuel and oil level, supply and/or condition. Check for visible

            wiring and connector problems or damaged components.

            3  Check and repair all ACTIVE/LOGGED diagnostic codes using the diagnostic procedures given in

            "Diagnostic procedures with a diagnostic fault code" on page 76.

            If ALL three of these inspections reveal no problems, identify probable causes using the procedure or

            procedures in this chapter that best describes the symptoms. Narrow the probable causes given in the

            procedure by considering operator information, operating conditions, and repair history of the engine.

            Operator information

            What happened, and when ?

            Under what conditions ?

            2300 Series

            Diagnostic symptoms

            Engine will not crank

            Test 1

            Note: This is NOT an electronic system problem, the engine starter motor wiring is not supplied by Perkins.

            Refer to the Workshop Manual and OEM Manual for additional information on the following tests.

            Probable root causes

            Battery cables/batteries

            Emergency stop switch

            Starter motor solenoid or circuit problem (in system wiring)

            Starter motor/flywheel ring gear

            Engine accessory

            Internal engine problem

            Perform the following tests

            1  Check battery post and battery cables for loose connections and corrosion. If corroded, remove and clean

            cables and connections. Check the optional battery disconnect switch.

            2  Check that the optional emergency stop switch is not engaged. Load test batteries. If necessary, charge the

            batteries.

            3  Test starter motor solenoid operation. Check the system wiring to starter motor solenoid.

            4  Test starter motor operation. Inspect starter motor pinion and ring gear for damage.

            5  Check that the timing pin was not left in the flywheel housing after setting valve clearances. Use the engine

            turning tool and attempt to manually turn the engine. If unable to turn the engine, remove and inspect engine

            accessories that can lock up the engine. Repair or renew as necessary.

            6  Remove injectors and check for fluid in the cylinders.

            7  Disassemble engine to inspect for internal components that may be seized, broken, bent, out of alignment,

            etc. Refer to the Workshop Manual.

            4

            2300 Series

            Engine cranks but will not start

            Test 2

            Probable root causes

            Starting aids/fuel waxing (cold temperature operation)

            Electrical connectors and wiring

            ECM software or ECM

            Engine speed/timing signal

            Electrical connections to the unit injector solenoids

            Fuel supply

            Restriction of the air supply or exhaust

            Combustion problem

            Perform the following tests

            1  If cold ambient conditions exist, check operation of starting aids. Check the coolant immersion heater for

            malfunction and replace if required. Check for presence of congealed fuel (wax). Repair as required.

            2  Check that the keyswitch and Injection Disable switches are closed.

            3  Check for correct installation of the ECM connectors J1/P1 and J2/P2, engine speed/timing sensor

            connectors J401/P401 and J402/P402, and unit injector connectors J300/P300. Check that the ECM is

            receiving the correct voltage.

            Note: Aftermarket engine protection devices may interrupt power to the ECM and prevent communications

            with the TIPSS-EST service tool. Check for correct installation and operation of aftermarket engine protection

            devices. Aftermarket devices may need to be bypassed to continue.

            4  If the engine has an unprogrammed ECM it will crank but will not start. Access ECM Status in the WinFlash

            PC program and follow the request to program the software. Refer to "Programming an ECM using flash

            programming" on page 27. Failure to program the software will cause the engine to not start or communicate.

            Cycling the key switch will allow access to the WinFlash PC program.

            5  Check that none of the diagnostic lamps are illuminated. If any are, turn the key switch OFF and ON to try

            and clear the fault. If the diagnostic lamps cannot be cleared refer to "Diagnostic procedures with a diagnostic

            fault code" on page 76. Check that the speed/timing sensors are correctly installed and that no diagnostic

            codes are active.

            6  Check that there is not an active 268-02 Check Programmable Parameters diagnostic code. If the diagnostic

            code is present, refer to "Programming an ECM using flash programming" on page 27.

            7  Observe the engine speed on the TIPSS-EST "Status" screen while cranking the engine. If the electronic

            service tool displays 0 rev/min while cranking the engine, there is a problem in the engine speed/timing sensor

            circuit. Refer to Test 46: Engine speed/timing circuit test on page 126.

            If the engine speed is greater than 50 rev/min the engine speed/timing circuitry appears to be operating

            correctly. Check that the timing reference gear is installed correctly and keyed to the camshaft by means of

            the locating dowel. If the gear was installed backwards or flipped over during assembly, the engine will not

            start.

            8  Check the calibration of the timing sensor and recalibrate if required. Refer to Test 47: Engine speed/timing

            calibration on page 134. Check for correct orientation between crankshaft and camshaft drive gears, repair as

            required.

            9  Ensure the unit injector connectors are correctly installed. Refer to Test 48: Injector solenoids circuit test on

            page 138 and perform the Injector Solenoid test as a quick check to confirm that the ECM can energize the

            unit injector solenoids. Ensure that the injection disable switch (if fitted) is ON.

            10  Check for a fuel supply problem and check fuel pressure. Refer to Test 29: Engine has a fuel supply

            problem on page 65.

            11  Check for combustion problems.

            4

            2300 Series

            Engine misfires, runs rough or is unstable

            Test 3

            Note: If the problem is intermittent and cannot be recreated, refer to Test 6: Intermittent low power or power

            cut-outs on page 42. If the problem is consistent and can be recreated, continue with this procedure.

            Probable root causes

            Cold mode operation (normal operation, if the problem occurs only after start-up)

            Battery cables, battery

            Electrical connections to the ECM

            Loss of backup engine speed/timing sensor

            Throttle position signal

            Faulty electronic unit injector circuit (individual cylinder malfunction)

            Fuel supply

            Air inlet or exhaust restrictions or air system leaks

            Internal engine problem

            Note: If the problem only occurs under certain conditions (high engine speed, full load or engine operating

            temperature, etc), then perform the test under those operating conditions.

            Perform the following tests

            1  Check indicator lamps; refer to Test 39: Inspecting electrical connectors on page 82.

            2  Check for a fuel supply problem and check fuel pressure.

            3  Check air inlet and exhaust systems for restrictions and leaks. Look for a diagnostic lamp indication, or

            tripped restriction indicators (if fitted) associated with plugged air filters. Replace plugged air filters, or clean

            filters, as described in the User’s Handbook, and repair any leaks found. Also refer to Test 41: Analogue

            sensor open or short circuit test on page 91. Refer to the Workshop Manual if an internal engine problem is

            suspected.

            4  Monitor the TIPSS-EST "Status" screen to check that the engine has exited cold mode and observe the

            coolant temperature reading on the electronic service tool. The engine should exit cold mode operation

            whenever the coolant temperature is above 17 °C (64 °F) and the engine has been running for five minutes.

            5  Check battery post and battery cables for loose connections and corrosion. If corroded, remove and clean

            cables and connections.

            6  Check the ECM connectors J1/P1 and J2/P2, customer connector, engine speed/timing sensor connectors,

            unit injector connectors and associated wiring for damage, abrasion or incorrect attachment. Refer to Test 39:

            Inspecting electrical connectors on page 82.

            7  Check the battery connection at the customer connector and ECM connector. Perform a pull test on the

            customer connector. Perform a pull test on P1 pins 48, 52, 53, 61, 63, 65 and 70. The wires should remain in

            the connectors during pull test. Refer to Test 39: Inspecting electrical connectors on page 82.

            8  Check that a 190-11 Loss of Engine Speed Signal diagnostic code is not active. If the 190-11 code is active

            check to see if a 342-11 Loss of Backup Engine Speed Sensor diagnostic code has been recently logged. If

            the electronic service tool indicates that a 342-11 code has been recently logged perform a pull test on the

            wires to the backup engine speed/timing sensor. Refer to Test 39: Inspecting electrical connectors on page

            82. If a 342-11 code has not been recently logged and the 190-11 code is active refer to Test 46: Engine

            speed/timing circuit test on page 126.

            9  Connect an electronic service tool to the service tool connector. Turn the key switch to the ON position,

            engine OFF. If a PWM speed control is fitted, check that a 91-08 Invalid PWM Speed Control Signal diagnostic

            code has not been recently logged. Monitor the throttle position from low idle to full throttle.

            10  Check for active or recently logged injector solenoid diagnostic codes. Use an electronic service tool and

            cut out each cylinder at low idle to isolate the misfiring cylinder(s). Refer to Test 48: Injector solenoids circuit

            test on page 138.

            2300 Series

            Low power/poor or no response to throttle

            Test 4

            Probable root causes

            Customer specified parameters

            Cold mode operation (normal operation if the problem occurs only after start-up in cold weather)

            Engine is in a derated mode

            Electrical connections to the ECM

            External speed control

            Faulty electronic unit injector (individual cylinder malfunction)

            Fuel supply

            Intake manifold sensor signal

            Air inlet or exhaust system restrictions or leaks

            Incorrect adjustment of full load setting or full torque setting

            Note: If the problem only occurs under certain conditions (high engine speed, full load or engine operating

            temperature, etc), then perform the test under those operating conditions.

            Perform the following tests

            1  Check for a fuel supply problem and check fuel pressure. Refer to Test 29: Engine has a fuel supply problem

            on page 65.

            2  Check air inlet and exhaust systems for restrictions and leaks. Look for a diagnostic lamp indication, or

            tripped restriction indicators (if fitted) associated with plugged air filters. Replace plugged air filters, or clean

            filters, as described in the User’s Handbook, and repair any leaks found.

            3  Check that the fault is not normal (programmed parameter) operation. Connect an electronic service tool

            and check the system/customer parameters. If a 268-02 Check Customer Or System Parameters diagnostic

            code is active, ensure ALL the system and customer parameters are programmed. Check that the injector

            codes are programmed. Check that the correct rating is programmed.

            4  Monitor the electronic service tool "Status" screen to check that the engine has exited cold mode. Observe

            the coolant temperature reading on the electronic service tool. The engine should exit cold mode operation

            whenever the coolant temperature is above 17 °C (64 °F) and the engine has been running for five minutes.

            5  The engine may be derated due to altitude or other factors. Connect an electronic service tool and check for

            active engine derates or diagnostic codes.

            6  Check the ECM connectors J1/P1 and J2/P2, customer connector and the relevant speed setting inputs and

            associated wiring for damage, abrasion or incorrect attachment. Refer to Test 39: Inspecting electrical

            connectors on page 82.

            7  If a PWM speed control is fitted, connect an electronic service tool to the service tool connector. Turn the

            key switch to the ON position, engine OFF. Check that a 91-08 Invalid PWM Speed Control Signal diagnostic

            code has not been recently logged. Monitor the PWM input. The duty cycle should be between 5 and 10

            percent at low load and increase at full load. If the throttle position change is erratic or out of range the problem

            is with the external speed control.

            8  Check that a 262-03 +5 V Supply Above Normal or a 262-04 +5 V Supply Below Normal diagnostic code is

            not present. If either of the codes are active refer to Test 41: Analogue sensor open or short circuit test on

            page 91.

            Intermittent engine shutdowns

            Test 5

            Note: Use this procedure only if the engine has shut down completely and has had to be restarted.

            Probable root causes

            Customer specified parameters

            Electrical connections to the ECM

            Faulty electronic unit injector connector

            Engine fault

            The ECM detects an engine fault, e.g. low oil pressure, etc. These fault codes may be viewed on the display

            modules or an electronic service tool. They are logged in memory except as noted.

            Note: If the problem only occurs under certain conditions (high engine speed, full load or engine operating

            temperature, etc), then perform the test under those operating conditions.

            Perform the following tests

            1  The engine may be shut down due to low pressure levels, or other factors. Connect an electronic service

            tool and check for active engine derates or diagnostic codes.

            2  Check the ECM connectors J1/P1 and J2/P2, customer connector, engine speed/timing sensor connectors

            and the unit injector connectors and associated wiring for damage, abrasion, corrosion or incorrect attachment.

            Refer to Test 39: Inspecting electrical connectors on page 82 for additional information.

            3  Check the electronic service tool for a logged 168-02 Intermittent Battery Power to the ECM diagnostic code.

            Check the battery connection at the customer connector and the ECM connector. Refer to the electrical

            schematic. Perform a pull test on the customer connector. Perform a pull test on P1 pins 48, 52, 53, 61, 63, 65

            and 70. The wires should remain in the connectors during the pull test. Refer to Test 39: Inspecting electrical

            connectors on page 82.

            4  If the problem occurs only after the engine is warmed up and disappears after the engine has been allowed

            to cool, the circuit breakers may be exceeding the trip point because of overheating. Check the circuit breakers

            on the engine, reset if required.

            Note: Aftermarket engine protection devices may interrupt power to the ECM. Check for correct installation

            and operation of aftermarket engine protection devices. Aftermarket devices may need to be bypassed to

            continue testing.

            5  Check switch status on an electronic service tool. If the switch status is incorrect, refer to "Machine wiring

            diagram (all options)" on page 18.

            6  Check for a fuel supply problem and check fuel pressure. Refer to Test 29: Engine has a fuel supply problem

            on page 65.
