Warning – Welding Welding can cause damage to the on engine electronics. The following precautions should be taken before and during welding: • Turn the engine OFF. Place the ignition keyswitch in the OFF position • Disconnect the negative battery cable from the battery. If the machine is fitted with a
battery disconnect switch then open the switch • Clamp the ground cable of the welder to the component that will be welded. Place the
clamp as close as possible to the weld. • Protect any wiring harnesses from welding debris and splatter. DO NOT use electrical components in order to ground the welder. Do not use the ECM or sensors or any other electronic components in order to ground the welder.
Warning - Electrostatic Paint Spraying The high voltages used in electrostatic paint spraying can cause damage to on engine electronics. The damage can manifest itself through immediate failure of components, or by weakening electronic components causing them to fail at a later date. The following precautions should be taken when using electrostatic paint spraying techniques on engines: • Connect all 64 pins of the ECM J1 Connector directly to the spraying booth ground. • Connect the engine block to ground at 2 points. Ensure that good screwed connections
onto bright metal are used.
Warning – Jump Starting Jump-starting an engine can cause higher than normal voltages to appear across the battery terminals. Care must be taken that this does not exceed the recommended maximum voltage for the ECM.

Engine Component Overview
Electronic Control Module (ECM) The A4E2 ECM is an electronic control device, fundamentally a computer that governs engine speed and torque output. The ECM processes sensor measurements from the connected sensors to determine fuel quantity, fuel timing, fuel pressure and intake pressure. The device is assembled to a special mounting plate fitted to the engine. The location is common on both 1104D and 1106D engines, left hand side close to the fuel rail. The device has 2 connection sockets, one for the engine wire harness (J2) that is blue in colour and the other for the machine OEM harness connection (J1) that is grey in colour. There are two ECM options, a fueled cooled version and an air-cooled version. The choice of option depends on the maximum ambient temperature (see mechanical installation guide for details of fuel connection requirements and temperature restrictions).
Sensor Details
Intake Manifold Pressure Sensor The intake manifold pressure sensor measures the air pressure inside the intake manifold, after the turbo. There are two sensor options dependant on the choice of rating. The operating range of the sensor options differs. The range is either 0-339 Kpa absolute or 0-440 Kpa absolute The sensor is used to determine atmospheric (barometric) pressure. During certain operating conditions the ECM will take a snapshot of the measured pressure to set the atmospheric pressure value. The atmospheric pressure is used to determine the atmospheric related fuel limits (if any) e.g. at high altitude fuel may be limited during cranking to prevent turbo over-speed. The ECM also uses the atmospheric value to calculate gauge pressure of other absolute engine pressure sensors. When the engine is running the sensor measurement is used as an input parameter to calculate torque and air fuel ratio limits. This helps prevent black smoke during transient engine conditions, mainly during acceleration or upon sudden load application. i.e. If intake manifold pressure is too low for the requested fuel, then the fuel is limited to prevent the over fuel condition. The measurement will also be used to select certain timing maps. Intake manifold pressure is also used to control the turbo wastegate regulator, if fitted. The turbo wastegate regulator control system regulates intake manifold pressure to a desired value, calibrated in the software. In order to do this, the software needs to know the actual value of intake manifold pressure, hence the need for the sensor measurement. If the intake manifold pressure sensor/circuit fails, then a low default value is used in the software. The wastegate regulator control (if fitted) will go to open loop, whereby the resultant intake manifold pressure will be low (as determined by the wastegate hardware chosen) and hence fuel will be limited under certain engine conditions, effectively providing a fuel/torque derate.
Intake Manifold Temperature Sensor This sensor measures the temperature inside the inlet air manifold .There are two sensor options on the 1104D engine depending on the turbo arrangement.The operating range of the sensors differs. The range is either –40°C to +120°C or –40°C to +200°C (used on straight turbo options). The 1106D engine uses the –40°C to +120°C option. Note that this is the sensor to which the engine is calibrated. Intake air temperature measurement is very sensitive to location. If the OEM adds additional inlet air temperature monitoring, for example during prototype evaluation, it should be

anticipated that there may be a difference of several degrees Celsius between the engine sensor and the OEM sensor. Intake manifold temperature measurement is used as an input to the cold start strategy. When the engine is running the sensor measurement is used as an input parameter to calculate torque and air fuel ratio limits. The OEM has no connection to this sensor, but if the intake air is required by some machine system, for example for fan control strategy, then the data can be accessed on the J1939 datalink. It is possible, if extreme temperatures are measured at the intake that the engine will derate. In the event of a derate, an event code will be generated on the J1939 datalink, or displayed on the service tool, and the warning lamp will illuminate.
Coolant Temperature Sensor The coolant temperature sensor measurement is used as an input to the cold start strategy. The measurement is also used to select certain maps at 0°C, 50°C, 65°C and 70°C. The engine is considered warm at 65°C. The fuel delivery characteristics will change dependant on the engine temperature. The sensor is also used for activating the glow plugs for cold engine starting and for detecting high coolant temperatures for raising an event. The range is –40C to +120C If the sensor/circuit fails, then a default value is used and a diagnostic code is raised. For glow plug control if this sensor/circuit is faulted, the intake manifold air temperature sensor is used. It is possible that with this sensor/circuit in a failure condition white smoke may result during a cold engine start. The high coolant temperature event will not be raised under this fault condition. The sensor reading of coolant temperature is also used to determine the maximum fuel allowed during engine starting. If the sensor/circuit fails, it is possible the engine will not start under cold engine conditions. It is possible, if the coolant temperature exceeds the design limits, that the engine will derate. In the event of a derate, a fault code will be generated on the J1939 datalink, or displayed on the service tool, and the warning lamp will illuminate.
Fuel Rail Pressure Sensor The fuel rail pressure sensor is used to measure the fuel pressure in the high-pressure fuel rail. (The fuel in the fuel rail then feeds all injectors. Injection takes place when each injector is electrically operated.) The fuel rail pressure measurement is used in conjunction with the high-pressure fuel pump to maintain the desired fuel pressure in the fuel rail. This pressure is determined by engine calibrations to enable the engine to meet emissions and performance objectives. If the fuel rail pressure sensor/signal is faulted, a diagnostic code is set with a warning; a default value used and a 100% engine derate results. The default value for fuel rail pressure will allow the engine to run in a limp home fashion whereby a known fuel rail pressure will be controlled within reasonable engine conditions. Emissions compliance cannot be guaranteed under this fault condition.
Fuel Pump Solenoid Fuel Rail Pump Solenoid is used to control the output from the high-pressure fuel pump. The fuel rail pump solenoid is energized when fuel is required to be pumped into the high-pressure fuel rail. Varying the energize time of the solenoid controls the fuel delivery from the
Perkins Confidential Green Production January 07

pump. The earlier the solenoid is energized (degrees before TDC), the more fuel is pumped into the fuel rail. The solenoid forms part of the fuel rail pressure closed loop control system in conjunction with the fuel rail pressure sensor, ECM and software. The fuel rail pressure sensor measures the fuel rail pressure; the signal is processed by the ECM and software and compared to the desired fuel rail pressure for the given engine operating conditions. The control algorithm then controls the fuel rail pump solenoid energies time. There is no OEM connection to this component. If the fuel rail pump solenoid fails, it is likely that fuel will not be pumped into the fuel rail and engine shutdown or failed start is expected.
Electronic Unit Injectors Each fuel injector contains a solenoid to control the quantity of fuel injected. Both positive and negative wires to each solenoid are wired directly back to the ECM There is no OEM connection to this component. Voltages of up to 70V are used to drive the injectors. The signals to the injectors are sharp pulses of relatively high current. The OEM should ensure that any systems that are sensitive to electromagnetic radiation are not in proximity to the harness components that lead to the injectors.
Crankshaft Speed/Timing Sensor The crankshaft speed-timing sensor is a Hall effect sensor. The sensor works in conjunction with the timing ring fitted to the engine crankshaft. The sensor produces a signal as the timing ring/crank rotates past the sensor. The ECM then uses this signal to calculate crankshaft speed and crankshaft position. The crank speed/timing signal is used during normal engine running since is more accurate than the signal obtained from the cam speed/timing sensor. If the crank speed/timing sensor/signal is lost or faulted, the engine is capable of starting provided the cam speed/timing signal is healthy. A diagnostic and warning will be raised if the fault occurs during engine running. A full derate will result since the engine is not then guaranteed to be emissions compliant due to the accuracy of the cam speed/timing signal. The diagnostic and derate will not be raised during engine cranking (if fault present), but the service tool will provide a means to read the condition of the cam and crank speed signals to aid fault finding. The OEM has no connection to this sensor. If the OEM requires accurate engine speed information then this may be obtained from the SAE J1939 datalink. The software includes logic to prevent reverse engine running.

Pump / Camshaft Speed Sensor The camshaft speed/timing sensor works in conjunction with the timing ring fitted inside the high Pressure fuel pump. The sensor produces a signal as the timing ring/pump rotates past the sensor. The ECM then uses this signal to calculate camshaft speed, camshaft position and engine cycle. The cam speed/timing signal is required for determining the correct engine cycle and is also used for limp-home operation in the event of the crank speed sensor/circuit being faulted/lost. If the camshaft speed/timing sensor/signal is lost or faulted, the engine will not start (since engine cycle is not known from the crank signal only), but if the engine is already running, no engine performance effect will be noticed. A diagnostic and warning will be raised if the fault occurs during engine running. The diagnostic will not be raised during engine cranking, but the service tool will provide a means to read the condition of the cam and crank speed signals to aid fault finding. The software includes logic to compensate for minor timing errors.
Oil Pressure Sensor The oil pressure sensor measures the engine oil pressure in Kpa. Oil pressure is used for engine protection, whereby if insufficient oil pressure is measured for a given speed, an event for low oil pressure would be raised. The low oil pressure threshold is defined as a map against engine speed. Currently, two levels of event are specified. Level 1 is the least severe and raises a warning. Level 3 is the most severe and raises a warning, which request the engine be shutdown. Automatic engine shutdown can be configured for certain applications, such as Gensets to occur when a level 3 event is raised. If the oil pressure sensor fails, a diagnostic is raised and a default value is used by the software, which has been chosen to be a healthy (high) pressure value. It is not possible to raise an event whilst an oil pressure diagnostic is present.
Wastegate Regulator The regulator controls the pressure in the intake manifold to a value that is determined by the ECM. The wastegate regulator provides the interface between the ECM and the mechanical system that regulates intake manifold pressure to the desired value that is determined by the software.

Customer System Overview Key Elements The engine can be wired and configured many different ways dependant on the requirements of the OEM. The key elements to consider are
Connection, Power and Grounding The engine ECM requires electrical power. The requirements for powering the ECM need careful review. It is important to understand how to connect the ECM to the machine battery, more detail is given in the power and grounding section of this document.
Indication Starting and Stopping the Engine With the battery connected a single connection to the ECM is required to initialize the ECM. Once initialized the ECM will be ready to control the engine. It is important to consider how the power to pin 40 is controlled, most machines use a simple key-switch to start and & stop the engine. There are specific recommendations for stopping the engine that are specified in the starting and stopping section of this guide. Mandatory requirements regarding operator indication are in place; see the operator display section of this document.
Controlling the Engine There are specific requirements in this document for controlling engine speed, and auxiliary components. Further information is available in the speed demand section of this document.

Example OEM Schematic The engine can be configured and wired many different ways dependent on the requirements of the OEM. The following four example schematics and descriptions provide a guide for the OEM.
Example 1 Basic Engine Application This solution is suitable for applications where very little integration or additional engineering is a requirement when compared to the solution used for a mechanical engine. This solution can be used in most mechanically governed engine replacement situations. The OEM needs to consider only basic functions these being Power Supply, Operator Indication, Cold Start Aid and a simple method of controlling the engine speed.
Example 2 Construction Application An application where the engine, in response to an arrangement of switched inputs will operate at one of a range of defined speeds. This is suitable for applications where the device has multiple operating speeds that are either defined for the specific output reasons, for simplicity of operator use or for operation dependent upon the environment - e.g. quiet modes. This could include: auxiliary engine on road sweeper, multiple speed water pumps, etc. There are sixteen possible set speeds based on four discrete ECM inputs. In addition to the Key-Switch a separate engine shutdown switch is used to stop the engine.
Example 3 Industrial Open Power Unit Application An application where the engine, in response to a control input, e.g. a button press, accelerates from idle speed up to the pre-defined operating engine speed. Once at the pre-defined operating speed, the engine speed may be raised or lowered by increment / decrement button presses. This is suitable for enhancing some of the applications of the single speed (set speed) control, or to provide a variable speed control without having a throttle pedal / lever. This functionality may benefit when the user wants to use ‘set speed operation’, but with the capability to adjust it themselves - users may have a favorite operating speed. This could include concrete pumps, hydraulic driven machines.
Example 4 Agricultural Application The application will allow single or twin throttles, engine twin set speed control, Multi mode operation, integrated display drive, etc. This set-up is suitable for applications where the customer requires a high degree of operator control over the machine’s behavior. It is one of the most complex applications. Typically this is used in mobile applications that may be driven to the place of work and then require operator selectable speed operation whilst performing their chosen task. This could include: Tractors, Combines, Backhoe loaders.

Power and Grounding Considerations
Engine Block Grounding Although the engine electronics are all directly grounded via the ECM connector, it is also necessary that the engine block be properly grounded to provide a good return path for components such as Starter Motor, Alternator and Cold Start Aids. Improper grounding results in unreliable electrical circuit paths. Stray electrical currents can damage mechanical components, and make electronic systems prone to interference. These problems are often very difficult to diagnose and repair.
Ground stud on Starter Motor If the Starter motor has a grounding stud then this should be used. The ground connection should be preferably be made directly back to the battery negative terminal. The starter motor ground path must not include any flanges or joints. Painted surfaces and flexible mounts in particular must be avoided. Star washers must not be relied upon to make contact though paint. The ground cable should be of cross section 67.4 mm² (00 AWG) or greater.
Ground Connection to Tapping on engine Block A separate engine block ground should be used in addition to the starter motor ground. A ground cable, direct from the battery negative or starter ground terminal, should be connected to a ring terminal which connects to one of the three tappings shown in diagram 1 and 2. The tapped holes will be reserved for customer use and can be used for grounding purposes. If a tapping is used then it should be checked to be free of lacquer, paint and dirt before the connection is made. A M10 metric screw should be used plated with Zinc. A washer should retain the ring terminal and the screw tightened to 44 Nm (32Ibft) It is preferable to use a conductive grease to ensure the reliability of this connection.

Power and Grounding Considerations
Voltage and Current requirements The ECM power supply requirements must be carefully considered when designing the supply circuit; there are specific limitations that must be considered in the design to ensure a reliable consistent power supply to the engine electronic components. The table provides the electrical characteristics and limitations for the A4:E2 ECM.

Max Peak Current 60A 60A
Peak Current Cranking 36A 36A
Max RMS Current* 13A 7.5A Suggested Fuse Rating** 25A 20A

Minimum ECM Voltage during Cranking
5.5V 5.5V
Maximum total ECM power circuit wire resistance

Target circuit resistance 40 mOhms 80 mOhms
*Max RMS current measurements conducted on engine running at rated speed and load. RMS current will vary with engine speed (assuming constant voltage) no Lamp Drivers or application side components fitted during measurement. ** Suggested fuse rating are based on automotive blade type fuses and are for guidance only. ***The ECM can survive higher voltages. ECM will survive for at least 2 minutes on a supply voltage of 30V for 12V systems and 48V for 24V systems.
ECM power supply circuit resistance Often during engine cranking the battery voltage will drop to values much lower than the normal system operating voltage. The minimum permissible voltage measured at the ECM during cranking is 6V. The power requirements to drive the engine electronic components such as the Injectors and fuel pump circuit remain the same during cranking; for this reason the ECM power supply circuit resistance becomes very important and will affect the voltage seen at the ECM. The table below illustrates the difference between the voltage at the ECM during cranking and normal running conditions:
Parameter Engine Cranking Engine Running System Voltage at the Battery 8 V 13.8V Engine ECM Current Draw 36A 36A Total ECM power supply resistance 40 mOhms 40 mOhms Voltage Drop (I*R) 1.44V 1.44V Voltage at the ECM 6.56V 12.36V
Perkins Confidential Green Production January 07
Page 29 of 119 1104D and 1106D Electronic Application and Installation Guide
The maximum permissible circuit resistance including positive and negative wires is 50mOhms for 12V systems and 100mOhms for 24V systems, however Perkins recommends that this value should not be targeted during design, as it is often difficult to predict the final circuit resistance when considering other factors such as fuse holders, connector resistance and aging. A target calculated circuit resistance including wire and connections of 40mOhms for 12V systems 80mOhms for 24V systems is recommended. The table below provides typical wire resistance for various cross sections of copper wire.

Battery (+) Connection The ECM requires four un-switched battery positive inputs; the inputs should be permanently connected to the machine battery. When the ignition key switch is off the ECM is in a sleep mode where it draws a very small residual current through the four battery connections. When the ignition key switch is turned on the ECM will become active. It is recommended, therefore that the ignition keyswitch is turned to the off position when connecting or disconnecting the ECM J1 connector, to prevent large sparks which may cause damage to the pins. The power supply to the ECM should be taken from the battery, and not from the starter motor terminals to avoid unnecessary system noise and voltage drops. Note that there are 4 ECM pins allocated for battery positive. All 4 pins must be used. The correct system voltage must be applied (12V or 24V), as the following components on the engine are system voltage sensitive: Wastegate Regulator Glow Plugs Alternator Starter Motor
Battery (-) Connection The ECM requires five un-switched battery negative inputs; the inputs should be permanently connected to the machine battery. Battery Connection – Do Not supply power to the ECM from the starter motor connections:

Engine ECM Power Supply Circuit Resistance Test It is not possible to accurately measure the machine ECM power supply wire resistance using a standard ohmmeter alone; it is therefore necessary to use a specific test circuit. The diagram and table below details the test apparatus used in the circuit to determine the engine ECM circuit resistance. The circuit consists of two voltmeters and a resistor connected to the J1 ECM plug that can be switched in and out of circuit using a relay. It’s very important to keep the test circuit resistance to a minimum, use a relay with low contact resistance (preferably silver oxide or gold) and short lengths of heavy gauge wire.

Inductive Energy – Fly-back Suppression Diode When an inductive load is suddenly switched off fly-back energy is introduced to the circuit. This is can be observed as a voltage spike. When using an ECM output to drive an inductive load such as a relay or solenoid, circuit protection needs to be considered. To prevent unnecessary ECM circuit loading use relays or solenoids with integral fly- back suppression components to suppress induced fly-back energy.

Note: The insulation should be stripped to 5 mm from the end of the wire. Only a single wire must be crimped into each terminal.
ECM connector sealing plug installation guidelines All unused connector socket slots must be filled with sealing plugs - Delphi p/n 12129557. Due to the small size of the sealing plugs, it may be quicker to install sealing plugs in all cavities, and then remove those which are not required, rather than to try to fit the sealing plugs when wires have already been inserted into the back of the connector. Note: do not use “non conductive” grease to seal unused terminal cavities.
OEM harness Retention at the ECM A wire strain relief component should be used to prevent ECM connector damage. The wire strain relief component is assembled to the engine ECM during engine manufacture and will be supplied on the engine. Wire bundle size may vary between applications. Cable tie/Wire tie slots are provided for correct bundle retention. Use the correct slots. Use Strain Relief and correct slots for the harness bundle size:

Harness Wiring Standards
General Recommendations for Machine Wiring harnesses The following are general “good practice” for wire harnesses. It is the responsibility of the machine designer to follow standards appropriate to the application type and to the geographical territory where the machine will be operated. These recommendations do not replace in any way any industrial standards or legislative requirements:
Connectors It is strongly recommended that high quality, sealed connectors are used throughout. Automotive standard components are not necessarily suitable as they are often only designed for a very low number of disconnect/reconnect cycles. Connectors should be horizontally mounted rather than vertically mounted to prevent ingress of water/chemicals. Whenever possible, connectors should be mounted such that they are protected from direct exposure to extreme cold. Connectors can be damaged by frost if water does penetrate the seals. Cables should not bend close to the connector seals, as the seal quality can be compromised. The correct wire seal must be selected for the diameter of wire used. Cables should be selected of an appropriate cross section for the current and voltage drop requirements Where large numbers of wires go to the same connector, it is essential that no single wire is significantly shorter than the others, such that it placed under exceptional strain.
Cable routing. Cables should be routed such that bend radii are not too tight. A cable should not be either in compression or tension, nor should it be excessively long or loose, such that sections may become caught or trapped. Clips should be used at regular intervals to support cables. These clips should be of the correct diameter to grip the cable firmly without crushing it. Ideally, harnesses should not rub against any mechanical components. The only points of contact should be clamps and connectors. If this is not possible then as a minimum they should not touch components that are hot, that move or vibrate, or that have sharp edges Conductors carrying high currents or voltages, particularly when these are alternating or switched, should be physically separated from conductors carrying small signal currents. In particular, high current and signal wires should not run parallel in the same harness bundle for any significant distance. Ideally, if high current wires must be in proximity to signal wires then they should cross at right angles. The engine wire harness should not be used by the installer for as a support for any components that are not supplied as part of the engine. For example, external hoses and wires should not be tied to the engine harness.
Mounting location for electronic modules The least harsh possible location should be selected for an electronic component or module, even one that is robustly designed. Select the mounting location carefully, therefore, considering exposure to frost, vibration, heat, mechanical damage, or ingress of water, dust or chemicals.

Care should be taken during design to ensure that components are accessible for repair and possible replacement in the field. Poor maintenance access may lead to poor quality repairs in the field.
Electromagnetic Compliance (EMC) Special measures should be taken to shield cables if the application is to be used in extreme electromagnetic environments – e.g. aluminum smelting plants. If screened cable is used, the screens should be connected to ground at one point only. That point should be central if possible

Diagnostic Connector A 9 pin diagnostic connector is fitted to the engine wire harness on all industrial engines. Various diagnostic and development tools may use the connector to access the engine data links. If the connector is inaccessible when the engine is in the application or no connector is fitted to the engine wire harness, provisions should be made to allocate an alternative location for diagnostic connection. In this case it is recommended that a diagnostic connector be wired in a location that can be easily accessed, free from possible water/dirt ingress and impact damage. The engine wire harness must not be changed or modified. To wire a diagnostic connection use the data link pins available on the OEM J1 ECM connector. It is recommended that all machines with an off engine diagnostic connector wire the J1939 CAN bus and the proprietary PDL data link. Mandatory Requirement for Prototype Machines It is mandatory for all prototype machines to have access to the engines PDL and J1939 CAN data links.
Termination Resistor It is recommended that termination resistors be wired to the OEM machine harness as stated in the SAE standard. If the engine is the only CAN J1939 devise ever present on the machine it is not necessary to wire the resistors. It is important to note, however that if devices such as handheld code readers, CAN PC tools or Navigation systems are installed in field later, resistors will be required. 9 Pin Diagnostic Connector Part Numbers

Starting and Stopping the Engine
Starting the Engine Unlike mechanically controlled fuel systems no customer connection to the fuel pump solenoid is necessary. To activate the engine ECM battery voltage needs to be constantly applied to pin 40. When the ECM is active the engine crankshaft needs to be rotated above a minimum cranking speed, a typical cranking speed is 180rpm (this will differ dependent on the application). Once the ECM has determined engine cranking speed and engine position, fuel pressure and delivery will be controlled. The most popular way to control engine starting is by a specifically designed 3 position key switch. The key switch controls battery voltage to the keyswitch input and the starter motor circuit. Some application may require a 4-position switch to run auxiliary equipment when the engine is not running.

Automatic Starting – Some applications need to be started automatically. There is no automatic start feature available on this product. If an automatic start sequence is required the following points must be considered: Start Aid - Wait to Start Control Starter Cranking Duration Starter Abutment Detection Number of Start Attempts Starter Disengagement Speed Warm Up Period Cool Down Period The ECM software considers the engine running when the engine speed is 100rpm below the desired engine speed or has reached 1400rpm, at this point after a predetermined period of time the engine will switch from cranking fuel maps to running fuel maps. It is important to note that starter motors must be disengaged earlier to prevent the starter motor being driven by the engine. The engine is considered stalled when the engine has dropped below 300rpm. When the engine is running the engine firing order is:

Stopping the Engine (and Preventing Restart) There is often some confusion about the different methods and devices used to either stop the engine or to prevent it from starting. These devices may be divided into the following categories:
• Ignition Keyswitch • Emergency Stop Button • Battery Isolation Switch • Remote Stop Button • Datalink stop
Each of these devices is described below to assist the OEM in selecting the method that is most suitable for his machine and his market. It remains, however, the responsibility of the OEM to ensure compliance of the machine with legislation in the territories into which it is sold. It is recommended that the OEM performs a risk assessment such as a Failure Mode Effects Analysis (FMEA) on the application to determine the most appropriate method of stopping the engine and/or preventing it from being restarted.
Ignition Keyswitch It is a Perkins requirement that all machines have an simple intuitive and accessible method of stopping the engine. This will normally be a directly wired Ignition Keyswitch. When the keyswitch is turned to the off position or when the key is removed, power must be removed from the ignition keyswitch pin (pin 40) of the ECM J1 connector.
Emergency Stop Button An emergency Stop button is a failsafe method for an operator to stop a machine to protect people or equipment. Emergency Stop buttons are defined by national or international standards in terms of colour, functionality, shape, size, latching /locking. In the EU for example, they are described in the Machinery Directive. For mobile machines, however, true emergency stop buttons are not always appropriate and are rarely fitted, due to the following issues:
• The legislation is designed principally for static industrial machinery (e.g. lathe) where the main power source is mains electricity.
• Stopping a diesel engine in a mobile machine may not always be safe. In particular the vehicle may need the power to move to a safe position (for example off the public highway, or off a railway track)
• In practice it is difficult to find components such as safety relays which are suitable for mounting on mobile machines due to the high vibration and water ingress protection, and the low voltages that occur during starting
• Fail-safe wiring can be a cause of machine unreliability and can create faults that are difficult to detect in the field.
If a true emergency stop button is required for an application it is recommended that it is implemented such that both the +battery and the ignition keyswitch lines are cut directly by the emergency stop button. Perkins do not provide a standard recommendation, or approval, for a circuit for multiple emergency stop buttons, as the differences between application mean that significant time and resources are necessary to design a system which will be fail safe without adversely affecting reliability.

Battery Isolation Switches Battery Isolation switches are usually fitted in the battery or the engine compartment of a machine. On some machines there may be a small number of low current devices which are not switched off by this device e.g. clocks or anti-theft tracking devices. The function of a battery isolation switch is as follows:
• Prevent battery discharge during vehicle shipping or storage • Protect service technicians from danger caused by inadvertent engine crank or start
.To offer good protection of service personnel is it possible to provide a switch which can be locked in the open position (e.g. with a padlock) and the key removed and given to the service engineer who is working on the dangerous components
The battery isolation switch is not a suitable method for stopping an engine, as it is not guaranteed to stop the engine as the ECM may continue to operate with power generated by the alternator. It is also possible that opening the battery isolation switch when the engine is running will cause an “alternator load dump”. This is a kind of electrical transient that can cause damage to electronic components Battery isolation switches are normally fitted in the negative path, close to the battery.
Remote Stop Button Remote stop is intended to provide a convenient method of stopping the engine. It is not designed to be fail safe and so should not be used assure the protection of either personnel or equipment Remote stop buttons may be used on large machines, which can be operated from ground level and where the operator wants to stop the machine without climbing into the cab. There are a number of variations on remote stop button circuits. The engine uses a single normally open contact, which must be closed to stop the engine. The remote stop button will function as follows: A single switch to ground input on pin 48 of the ECM J1 Connector (Several stop buttons can therefore be connected in parallel) When the switched is closed (or if a button is stopped for longer than 150mS), then the engine will stop. The ECM will remain ON, so it will continue to communicate over J1939 and with the service tool. Note however that it will continue to draw power from the battery so if it is left in this state it will eventually result in a flat battery.

48 REMOTE STOP SWITCH
ECMJ1Remote Stop Button
The engine may be restarted by opening the switch and activating the starter motor. The red “mushroom” emergency stop buttons must not be used for remote stop functions as they may be mistaken for emergency stop buttons as described above.
Datalink stops It will be possible to stop the engine via a datalink (J1939 or PDL). As per the remote stop button, described above, the datalink stop is not fail safe and does not meet the requirements of emergency stop legislation so should not be relied on to assure the safety of machine operators or other personnel.
Perkins Confidential Green Production January 07
Page 47 of 119 1104D and 1106D Electronic Application and Installation Guide
Datalink stops may be used in the following circumstances
• Immobilisers • Machine protection strategies • Automatic machine features (e.g. idle shutdown timer) • Stopping machines by radio control or other telemetry. Geo-fencing is a particular
application, where a machine will not operate outside defined map coordinates It is recommended that if such features are implemented, then they are clearly documented and communicated to the final users and owners of the machine. If this is not done then there may be complaints that the engine is stopping unexpectedly.
Common problems with the application of stop devices • It is possible, although extremely rare, that diesel engines continue to run even if all
electrical power is removed. This can happen when high quantities of oil vapour or other inflammable gases are present in the air into the engine. The only way to prevent this is to provide an air inlet shut-off valve (slicer valve). It is not common practice to fit such devices to all engines, but they should be considered where there is a risk of flammable gases (e.g. in petroleum applications), or where the application demands high engine gradebility (slopes)
• Some hazards are present when the engine is being cranked by the starter motor, as well as when it is running. For example, components will still rotate, hydraulic pressure will still be present, fuel may still be pump to high pressures.
• If an emergency stop button is pressed, to cut power to ECM and ignition, but is released while the engine is still turning, it is possible for the engine to continue to run.

Engine Speed Demand It is necessary to select a device that converts the speed requirements of the engine operator or controller to an electrical signal recognized by the engine ECM. There are five types of speed demand input: • Pulse Width Modulation (PWM) Sensor • Analogue Sensor • PTO mode - also known as “engine speed cruise control” or “set speed control”. • Multi Position Throttle Switches (MPTS) • Torque Speed Control - TSC1 (Speed control over CAN J1939) The speed demand type must be carefully considered and appropriate for the application. The options must be selected at the time of engine order so that the ECM will be configured correctly, for the type or pedal, lever or control device selected. There are two dedicated software input channels that can be configured to accept specific types of speed demand inputs. The valid combinations and throttle logic are given in the following diagram. PTO mode can be used with Analogue/PWM combinations; it cannot be used with multi position switch. The J1939 TSC1 parameter will override any speed demand input when broadcast. Droop is applied to the requested desired engine speed.

The Analog sensor should use non-contact Hall effect technology. Robust potentiometer contact sensors designed for use in vehicles may be considered under no circumstances should ordinary carbon track or wire wound potentiometers be used, as they will not be reliable. For all mobile applications, and those where a rapid change in engine speed could cause a hazard, an idle validation switch is required. The idle validation switch closes to ground when the sensor is in the minimum position. Off idle switches and kickdown switches are not monitored by the engine ECM. This Analogue input must only be used to control engine speed from a direct operator input, and is not suitable as the mechanism for speed control by another electronic controller. There is no special requirement for a relationship between angular movement of the pedal and output voltage. This document does not measure component acceptability in terms of:
• Temperature • Vibration • Electromagnetic Compatibility • Design life • Supply voltage requirements (min, max, stability) • Legal Compliance
It the responsibility of the OEM and the throttle device manufacturer to ensure that the component is suitable for the application in which it is to be used.

PTO mode PTO mode has also previously been referred to as “engine speed cruise control” or “set speed control” PTO mode cost effective way to control engine speed as for the minimum implementation it only requires buttons to raise and lower engine speed. Another benefit is that it can be used in an application where it is necessary to control the engine speed from several different points on the machine. Likewise, it is a simple method controlling engine speed by another controller The disadvantage of controlling speed via PTO mode is that it takes some time to ramp up or down to the required speed.

ON/OFF switch When this switch input is open then the PTO mode cannot be engaged, and none of the other buttons will have any effect. When the switch is turned off, any adjusted memorized speed will be lost.
Set/lower Button When the PTO mode is on but not engaged, the first time that the set button is pressed it will save the current engine speed as the memorized speed, and the engine will try to run at this speed. Once that a PTO speed has been engaged, if the pressed again, or if it is held down, then the engine speed will be lowered.
Raise/ Resume Button If the resume button, is pressed before the set button, immediately after start or after switching ON the cruise control ON/OFF switch then the engine will go to the preset speed as described below. If a the PTO mode has already been engaged by the set button, then the resume/raise button can be pressed or held down to increase the speed. After the PTO mode has been disengaged using the disengage switch described below, then pressing the Resume/Raise button will set the engine speed to the last memorized speed.
Disengage Switch The disengage switch input is opened the engine speed will not follow the memorised speed, but will return to the next highest engine speed demand The disengage switch may be a operator panel switch, or may be a micro switch on the brake, clutch, or other component of the application

Multi Position Throttle Switch (MPTS) Four switch inputs are available on the ECM for a switch-controlled throttle. The ECM may be configured so that different combinations of switch inputs will relate to different engine speed demands. There are 16 different combinations of states of these 4 switches, although not all of these combinations need to be programmed.

If a switch combination is detected which has been configured as “Not Valid” then a fault code will be raised and the ECM will ignore the MPTS for the rest of the key cycle. This is a very powerful and flexible feature that may be used in a number of ways. For example:
• Principal speed control method in a hydrostatic machines where engine speed is selected and then not required to be frequently changed by the operator. It is in this respect a good alternative to a hand throttle as the speeds selected on the switch. can be designed to correspond to the optimum operating speeds of hydraulic pumps. A rotary encoded 10 position switch component is available for this function. Please contact the electronic applications team for further details.
• Machine limp home speed feature. For example, if the normal throttle fails the operator could remove a fuse or a link and the engine would go to a speed that would allow the machine to be moved. In this application only one of the available 4 switch inputs would be used.
• Elevated idle. For example the OEM could increase the idle speed when work lights are switched on so that the alternator will provide sufficient current to recharge the battery. In this application only one of the available 4 switch inputs would be used.
The following table illustrates how the ECM may be configured for a 10 position rotary switch. Multi-Position Switch Configuration Example Switch 4 Switch 3 Switch 2 Switch 1 Switch

The service tool configuration allows the user to specify the number of switch inputs to use. It is recommended that where possible the user configures 4 inputs and mark those not used as ‘not valid’. If however the user chooses to configure less then 4 inputs using the service tool the physical input allocation vs software input description changes as described in the table below.

Multi Position Throttle Switch - EST Configurable Parameters The throttle configurable parameters must be configured in Perkins EST prior to using the MPTS feature. The parameters are selectable in the main throttle configuration screen.
Torque Speed Control TSC1 (Speed Control Over CAN) A special J1939 message called Torque/Speed Control #1 (TSC1) allows other electronic devices to control or to limit the engine speed. This message is explained in detail in the J1939 section of this application and installation guide
Arbitration of speed demand In applications where there is more than one source of engine speed demand, it is necessary to arbitrate between the different demands. There are 3 methods of arbitration:
• Max Wins. The highest speed demand is the one that controls the engine. This is the default configuration
• Manual Selection switch. A switch input can be used to define which speed input has control. This is particularly useful in applications where there are 2 driver seat positions.
• TSC1 override. As described above, the Tsc1 message over J1939 will override speed demand from any other source.
Manual Throttle Selection Switch A switch input is available on pin 47of the ECM J1 connector, which can be configured to manually select the active speed demand channel. If the switch input is open then Speed demand 1 is selected. If the switch is closed then speed demand 2 is selected.
Ramp Rate It is possible to limit the overall acceleration rate of the engine speed. The acceleration limit applies to overall engine speed, irrespective of applied strategy. The rate may be configured in ET. The rate is defined in units of rpm per second. 0 rpm/s represents no limit to engine acceleration (i.e. turns off the feature.) The default ramp rate will be 0 rpm/s.

Throttle Calibration The majority of throttle components have mechanical and electrical tolerances that affect the final output of a device, for example two components of the same design and part number may produce a different voltage output in the open position. Also after a period of time throttle components can mechanically wear, affecting/changing the output of a device. To accommodate these differences and changes the engine ECM may be configured to automatically calibrate to differing input values at the upper and lower positions. The diagrams below give an example pedal design where the open and closed position of the throttle pedal are set by adjusting the manufacturing adjustment screws. With this type of arrangement the mechanical accuracy is limited and therefore auto calibration may be used. The calibration control logic needs a number of parameters specific to the chosen device to allow auto calibration. This feature is configurable for Analogue and PWM inputs. The algorithm treats either a PWM or analogue input as a ‘raw signal’ in the range 0 to 100% for example the analogue voltage range is 5V therefore 0.05V is treated as 1%. Several parameters are used to: Define the boundaries for calibration in the open and closed positions Define the amount of ‘deadzone /play’ from the open and closed positions Define the upper and lower diagnostic boundaries

The diagram above is a simplified representation of a throttle pedal assembly; a small lever attaches the pedal to a throttle position sensor. Two lock screws limit the open and closed pedal movement, one for each position. The lever movement is directly proportional to the electrical output signal of the throttle sensor. The electrical raw signal is shown as a percentage of the total permissible input range. Eight parameters are shown on the diagram scale, each parameter has a purpose; these parameters are required for correct calibration. The parameters are expressed as a percentage of raw signal, the parameters may be changed/configured to match the chosen device:

Throttle Parameter Description Diagnostic Lower Limit The lower diagnostic limit is the absolute minimum raw value accepted as a valid signal by the engine ECM. Any values below this point will flag appropriate diagnostics and invoke the limp-home strategy. Most analogue devices are classed as faulted with a voltage of 0.25V and below (5%) this is to prevent a possible open or short circuit being mistaken for a valid signal, for similar reasons a PWM duty cycle should not fall below 5% duty cycle. Lower Position limit This is the minimum point of the lower calibration boundary Initial Lower Position limit This is the maximum point of the lower calibration boundary. This value is also used as the initial lower position when no calibration has been applied. Lower Deadzone This position is given as a discrete raw signal percentage value. The lower dead zone effectively gives some play at the lower position. This dead band is expressed in terms of a raw signal percentage, such that the initial lower position plus the lower dead zone will give the 0% throttle position. Initial Upper Position limit This is the minimum point of the upper calibration boundary. This value is also used as the initial upper position when no calibration has been applied. Upper Position Limit This is the maximum point of the upper calibration boundary Upper Deadzone This position is given as a discrete raw signal percentage value. The upper dead zone effectively gives some play at the upper position. This dead band is expressed in terms of a raw signal percentage, such that the initial upper position minus the upper dead zone will give the 100% throttle position. Diagnostic Upper Limit The upper diagnostic limit is the absolute maximum raw value accepted as a valid signal by the engine ECM. Any values above this point will flag appropriate diagnostics and invoke the limp-home strategy. Most analogue devices are classed as faulted with a voltage of 4.75V and above, this is to prevent a possible open or short circuit being mistaken for a valid signal, for similar reasons a PWM duty cycle should not go above 95% duty cycle.

Throttle Calibration Function When the engine ECM is active the raw throttle signal is continuously monitored. The following diagrams explain how the automatic calibration functions. The adjustment screws in the diagram have been purposely adjusted and differ from the previous throttle pedal diagram. When the engine ECM is active the raw throttle value is checked, if the value falls within the lower calibration region (defined by the ‘lower position limit’ & ‘Initial lower position limit’) calibration will take place. In the diagram below the lever position is at 11% and falls within the lower calibration area so auto calibration will be applied.

Diagram A, before calibration, the sensor output falls within the lower calibration region, without auto calibration the ‘initial lower position limit’ is used by the engine ECM as the throttle start point. Once clear of the deadzone the desired engine speed will change. In this case the lever would have to move 14% of the raw signal (9% + 5% deadzone) before desired engine speed changes. This is situation is undesirable.

Idle Validation Switch Analogue devices must use an idle validation switch. The idle validation switch is required to validate that a change in signal is indeed valid and not a potential electrical fault. Two parameters need to be defined for correct operation. When configured the engine ECM continually monitors the speed demand request and the Idle validation switch. Idle validation maximum ON threshold (Closed) The value is defined as percent raw signal. At low idle the Idle Validation switch should be ‘ON’ (the input should be switched to ground). When increasing engine speed the ECM will continually monitor the idle validation switch. The switch needs to have switched ‘OFF between the two IVS thresholds. If the switch state does not change by the ‘Idle validation maximum ON threshold’ the ECM will invoke the limp home strategy and the throttle will not respond. Idle validation minimum OFF threshold (Open) The value is defined as percent raw signal. At high idle the Idle Validation switch should be ‘OFF’ (the input should be switched to open). When decreasing engine speed the ECM will continually monitor the idle validation switch. The switch needs to have switched ‘ON’ between the two IVS thresholds. If the switch state does not change by the ‘Idle validation minimum off threshold’ the ECM will invoke the limp home strategy and the throttle will not respond.

Cold Starting Aid.
Control of Glow Plugs by the Engine ECM Glow plugs are fitted as standard on the 1104D and 1106D. When the ignition key switch is switched ON, the engine ECM will monitor the coolant temperature and the inlet air temperature and decide whether the glow plugs are required. If so then the ECM will drive ECM connector pin 57 to ground, activating the glow plug relay. The Glow plug relay is supplied and fitted by the OEM.

The relay coil should not draw more than 1A and should be fitted with either a resistor or diode to suppress flyback energy (back emf) when the relay is de-energized. As the glow plugs may be activated during cranking, when the battery voltage may be low, it is recommended that relay is specified such that it will close at a voltage of 60% of nominal battery voltage or lower. The relay contacts should be rated to withstand the current characteristics outlined in the table below. Note that for the purpose of relay specification, the glow plugs are a purely resistive load (no inductive element). Although the glow plugs are normally operated only for a short time, in cold ambient conditions, best practice would be to size the cable to withstand the stabilized glowplug current permenantly. This will allow for a relay that fails closed. For example a 4 Cylinder 12V application should have wire sized to carry 50A. Refer to the recommended cable sizes in the table below.

Wait-to-Start / Start Aid active lamps On a cold start, when the ECM decides that it is necessary for the glowplugs to be activated prior to starting, a lamp output will indicate to the operator that he needs to “wait to start”. Note that it is possible that start aids will also be used either during cranking or when the engine has started. The wait to start lamp will not be active in these conditions. For further information refer to the Lamp Output section. Note that the ECM will also transmit a parameter on the J1939 datalink indicating the status of the Wait to Start lamp (see section on J1939 support).

OEM / Operator control or override of the Glow Plugs The ECM glow plug control strategy has been developed in a cold chamber to be suitable for the majority of applications. There may be some applications that require a specially adapted strategy for control of the start aid. In such cases it will be necessary for the OEM or operator to control the start aid. Examples of applications that may require special starting strategies are:
• Engines in extremely cold climates that are fitted with block heaters. • Engines that drive high loads during run up e.g. compressors.
Busbar connection point
An insulated M6 terminal post is provided for the machine harness connection to the busbar, this is located to the top right hand side of the ECM bracket. A 5.5-6 mm diameter ring terminal is required to connect the machine harness; this should be capable of handling an 80Amp current and insulated by a terminal insulator cap. The existing terminal nut is used to locate both the engine-side and harness-side ring terminals to the post. A 10mm ring spanner is required to tighten the terminal nut to a torque of 6 Nm ± 2Nm. Customers who paint their engine are required to shield the terminal post prior to painting.

A location should be chosen that avoids any radiated or conducted heat produced by the engine water jacket heater. The location and mounting design should protect the sensor from damage; the sensor probe is particularly vulnerable and should be guarded from possible impact damage.
NOTE: Do not splice the sensor signal wire for input to third party devices. Recommended connector mounting for component with a pigtail harness: The connector interface should never be tied directly to a vibrating member. Pigtail wire lead should be tied down on only one side of the connector interface.

Operator Displays
Gauge Drivers OEM’s are increasingly selecting datalink driven intelligent displays for their applications, instead of traditional gauges and lamps directly driven from sensors or engine ECM. If a needle type Analog gauge is required, to display an engine parameter such as engine speed, oil pressure or coolant temperature, then it is recommended that the OEM uses a gauge or display that can use the parameters broadcast by the ECM on the J1939 datalink. As an alternative, traditional single wire gauge “senders” may be used if a suitable tapping is available. If this implementation is required, then please contact the electronic applications team to discuss requirements. A traditional tacho signal may be obtained from the “W” terminal of the alternator, although this will not be as accurate as the value sent on the J1939 datalink. Warning: The engine wiring harness must NEVER be modified to use the signal from the sensors connected to the engine ECM. This action would invalidate the engine warranty.
Lamp Outputs The lamp strategy is designed to display the maximum amount of information on the minimum number of lamps. There are six lamp outputs available:
Lamp Description Pin Allocation Red Stop Lamp Pin 60 Amber Warning Lamp Pin 59 Wait to Start Lamp (Cold Start Aid) Pin 63 Oil Pressure Lamp Pin 62 PTO Mode Lamp Pin 61 Maintenance Due Lamp Pin 58 It is mandatory for the OEM to fit the Red Stop Lamp (1), Amber Warning Lamp (2) and the Wait to Start Lamp (3) unless a datalink driven intelligent display is fitted, which fulfils the specification outlined in the next section. Lamps four, five and six are optional.

Datalink Driven Intelligent Displays Displays may be connected to the engine ECM using J1939 datalink. Some products that use the PDL may also be compatible. Please contact your local applications team to confirm before selecting a PDL display. Devices that are connected to the J1939 datalink should meet the following standard if the OEM does not intend fitting the indicator lamps, described above.
Minimum Functional Specification for J1939 display. • The display always on when the engine is running • The display should be line-of-sight of machine operator during machine operation • Display of the whole J1939 fault code including Suspect Parameter Number, Failure
Mode Indicator, and Occurrence number. • Clear indication of what action, if any the operator is required to take. • Display of engine speed • Audible or bright lamp warning when new fault code is detected • The scaling of any gauges (e.g. coolant temperature) should be such that the needle
is not far to the right of vertical when the engine is in normal operation (this would give the impression that the engine was abnormally hot, when in fact it is running within it’s design limits).
Perkins will under no circumstances change the engine J1939 implementation in order to resolve compatibility issues with gauges or displays other than those supplied directly by Perkins. Gauge manufacturers may contact the Electronic Applications team, however for information and assistance in ensuring that their products are compatible with the engine ECM. To support new standards and requirements Perkins may add to the fault code table. Therefore any active engine fault codes including those not recognized or referenced should be displayed. Perkins recommends that any suspect parameter number and the associated failure mode identifier are displayed.
Customer Triggered Engine Fault codes The engine will raise fault codes (event codes) when it’s design limits are exceeded. For example, for excessive coolant temperature. The fault code algorithms are carefully designed and validated so that they do not cause spurious codes when there is in fact no fault. Some intelligent instrument clusters available on the market are also capable of raising fault codes themselves, based on the information that the engine transmits on J1939 such as “engine coolant temperature”. The machine designer could set a limit that is more conservative (lower) than the warning threshold defined by Perkins. This raises the possibility that the display will say that the engine has a fault, when the engine is in fact running within its design limits. This is undesirable as it may result in a service technician being called to resolve a “problem” when in fact no problem exists. It will also cause damage to the reputation of Perkins and of the OEM. Perkins recommend therefore, that intelligent display DO NOT have their own fault detection for engine over temperature / oil pressure etc, but that they use the fault codes generated by the engine, sent in the J1939 “Diagnostic Message#1 (DM1)”.

Engine Software Features
Engine Monitoring System Software will monitor the engine during operation and in extreme conditions make decisions to protect the engine from damage. The values of four main operating parameters are monitored Engine Coolant Temperature, Engine Oil Pressure, Intake Manifold Air Temperature and Engine Speed. The monitoring system will compare parameters predetermined as dangerous to the engine and depending on the parameter values take appropriate action. There are three levels of action Warning, De-rate and Shutdown. General All parameters work independently using individual threshold values and guard timers. Consequently, it is possible for more than one parameter to register a warning or de-rate condition at any one time. Warning Each monitored parameter has its own warning trigger threshold. A warning will be triggered when any parameter equals or exceeds its warning. In addition, for oil pressure, the trigger threshold varies with engine speed. The ECM will log these events and turn on the appropriate lamp driver. De-rate Each monitored parameter that uses the de-rate function has its own de-rate trigger threshold. If the de-rate threshold is equaled or exceeded by any parameter for a de-rate protection will be set active. The engine will de-rate. The ECM will log these events and turn on the appropriate lamp driver. Whilst de-rate protection is set active, the de-rate percentage may vary with parameter value Shutdown The engine shutdown indication lamp driver will be triggered when any parameter equals or exceeds it shutdown threshold for a time exceeding its shutdown indication guard time. Physical engine shutdown will occur only if enabled by the configurable parameter. The ECM will log these events and turn on the appropriate lamp driver. Note: All values quoted in tables below are subject to change. Also, the percentage derate can be confusing. 100% derate does not mean that the engine has no power at all, it means that the engine will be running on a derate rating. The percentage of normal power that is available on the derate curve will depend on the rating used, but will normally be approximately 50% of nominal power

Engine Governor All speed The default governor type is an All Speed Governor, also known as a variable Speed Governor. The diagram below illustrates the torque and speed characteristics of this governor
Torque limit curve Note that the engine may not be capable of reaching the torque fuel limit curve in some circumstances. For example, if the turbocharger is not providing the required boost pressure, then the fuel will be limited so that the engine does not emit black smoke
Droop Droop is the variation of engine speed as load is applied. For example, if an engine has 10% droop and is running at 1500RPM without load, then as load is applied the operator will feel and hear the engine speed gradually decreasing. This is represented by the diagonal dotted lines under the torque curve in the diagram below. When the load reaches the torque limit curve of the engine, the engine will lug back along the curve. Note that droop values can be assigned to the multi-position throttle switch input, PWM accelerator pedal/lever input and the TSC1 speed demand over J1939. Droop does not apply, however to the PTO mode, which always operates isochronously (0% Droop)
High Speed Governor (Governor Run-Out) The parameter Top Engine Limit (TEL) will no longer be offered on the 1104D and 1106D engines. Flexibility is improved, however, by allowing the high idle (HI) speed to be configured. High Idle is the maximum speed that the engine will reach. Note that this is on the bare engine and when installed in an application, it may not be possible to reach this speed due to the parasitic loads of the driven equipment. The range of possible high idle speeds is defined by the parameters High Idle Lower limit (HILL) and High Idle Upper Limit. (HIUL). High Idle cannot be specified to be less than Rated Speed (RS) and the HIUL will be dependant on the mechanical limits of the engine. The rated speed (RS) may not be changed by customer configuration.

Auxillary Governor It is possible to control the engine by the output shaft speed of another module. Perkins do not offer a speed sensor for this component, nor is there a direct speed sensor input, however this is for the following reasons:
• There are a wide variety of speeds to be measured • Speed sensors output signals are low in amplitude and sensitive to electromagnetic
interference • The engine is often not close to the output shaft to be measured, thus resulting in
poor quality speed signals The recommended solution for this requirement is as follows The speed measured close to the output shaft by a third party electronic control module, which would give an engine speed demand to the engine, either using by switch the PTO raise and lower buttons. The third party module could also incorporate a display and/or operator control buttons. The electronic Application team can give advise on specifying and selecting the third party electronic module for this function. The advantage of this approach is that, although the initial cost of the additional module is higher than a direct speed input, the cost of the additional components is reasonable and the advantages in reliability and ease of commissioning outweigh the disadvantages.
Rating selection via Service Tool Some engines will have the capability to run more than one power rating. If this is the case then the highest allowed rating may be changed via the “rating” parameter on the confitguration screen of the service tool. Note, however that the engine may not be running the highest enabled speed due to the status of the mode switches or due to requests from another electronic module on the machine over J1939 datalink.
Mode Switches A mode is a performance characteristic in terms of power / torque, Droop and rated speed. There are up to 4 modes configurable on the 1104D and 1106D engines, and these can be selected in operation when the engine is running and on load. The mode switches are of the Switch to Ground type and the ECM J1 pin connections are as follows: Function ECM - J1
connector pin
assignment Mode switch 1 39 Mode switch 2 46 The following table is an example of how the mode switches can be configured. The 2 switch inputs provide a total of four possible combinations. Two ratings have been configured such that if switch 2 is open the engine will run on the lower rating, and if the switch is closed it will run on the higher rating. Switch 1 is configured such that if it is open then the droop on throttle 1 and 2 is 10%, which may be suitable for road operation in an agricultural tractor, for example. When Switch 1 is closed, however, a tighter droop is applied which may be suitable in “field” or “work” operation Note that the highest rating available in the mode switch feature will be defined by the “rating” parameter on the configuration screen of the service tool

Service Maintenance Indicator A service maintenance indicator option is available. This is a configurable option; its purpose is to inform the operator that a pre-determined time set in the service tool has elapsed. The feature may be installed using the EST service tool. When configured, the default configuration for the service interval is 500hrs. This can be configured through the service tool configuration screen. The number of hours cannot be increased above 500hrs however the hours may be decreased to a lower value. · Disabled - no monitoring needed · Manual Hours - software monitors hours since the last reset When the number of hours since the last service is greater than configured maintenance interval the software will permanently illuminate the maintenance due indicator lamp connected to J1-58. The number of hours until the next service, displayed in EST, will also become negative, i.e. two hours past the service interval will be indicated by –2.The maintenance due indicator lamp is available in the service tool as a status parameter, “Maintenance Indicator Lamp Status”. The override “Maintenance Indicator Lamp Override” such that the lamp status can be overridden for testing purposes. At any time, before or after the maintenance interval has expired, the maintenance due counter can be reset through any of the following mechanisms: · Using the Maintenance Due service tool feature, the maintenance due counter will be reset when the reset button is clicked. If Pin J1-36 (SWB) is held high for greater than two seconds. · If the ECM receives J1939 SPN 1584, “Service Component Identification”, with data value (decimal) 32, “Engine oil-engine #1”, the maintenance due counter will be reset. (If the SPN is received with any other data value it will be disregarded.)

Using the EST service tool. The latest version of EST will be required to view or modify some of the 1106D engine software parameters and features. It is important that the engineer regularly updates their service tool to ensure compatibility. In addition it is the responsibility of the engineer to confirm software release dates. During project engine development features may not be available or viewable and may be dependant on later software release dates.

Datalink Support There are 2 datalinks available for OEM connection to the engine. J1939 and Perkins Data link (PDL). It is recognized, however that other CANbus standards (higher level protocols) do exist and are used in off-highway applications, so some notes are also provided for users of those standards.
SAE J1939 The SAE J1939 standard was initially developed for the US truck and bus industry. It has been expanded and is now the most widely used datalink standard for industrial powertrains, with compliance from almost all engine manufacturers and most transmission manufacturers.
Summary of Key J1939 Application Issues This is a summary of some of the key points and answers to frequently asked questions relating to design of a J1939 compatible network. It is intended to give a design overview and does not in any way replace or contradict the recommendations contained in the SAE J1939 standard documents.
Physical layer • The data rate is 250 KBits/sec • Twisted pair cable, of a 120Ohm impedance characteristic, should be used throughout.
Note that most commercially available twisted pair cable is not suitable. • It is recommended that this cable is shielded (as per J1939-11)and that the screen is
grounded at a central point in the network. Unshielded-twisted pair cable is used by some machine manufacturers, however (as per J1939-15), offering lower cost but lower immunity to electromagnetic noise.
• The bus is linear and should be terminated with 120-Ohm resistors at either end. It is a common mistake to use one 60-Ohm resistor instead of two 120-Ohm resistors. This does not work correctly however.
• Maximum bus length is 40m • The terminating resistors should not be contained in Network Nodes • Network nodes are connected to the bus via stubs of maximum recommended length 1
meter.
Network Layer • J1939 recommends a bit sample point of 87% . This relatively late sample point gives
best compromise for immunity to noise and propagation delay. It does restrict the size of the software jump width (SJW), however.
• All nodes should have the same bit timing • Accurate bit timing is essential (4μs +/- 0.2%) • It is recommended that the average bus load is not greater than 40% • Hardware filtering (masking) of CAN messages should be used under high bus loads to
limit demands on processors. • The Engine ECM always assumes a fixed address 0. It will not change it’s address in the
arbitration process described in J1939-81 • The multi-7packet protocol (described in J1339-21) is used for sending messages with
more than 8 bytes of data. In the Perkins application this will be used principally for the diagnostic messages DM1 and DM2.
• Information may be broadcast, at regular intervals, or requested. For example the engine will broadcast its “current speed” every 20ms but it will only send “hours run “ information if another node requests it.
Application Layer • The messages (PGN’s)supported by Perkins ECM are only a subset of the messages
described in J1939-71 and J1939-73
Perkins Confidential Green Production January 07
Page 85 of 119 1104D and 1106DD Electronic Application and Installation Guide
• Some PGN’s may be partially supported i.e. only those bytes for which the ECM has valid data will be supported.
• Unsupported data bytes are generally sent as FF (hex) and incorrect or invalid information is sent as FE.

The Torque/Speed Control #1 (TSC1) PGN allows other electronic devices to control the engine speed. Although originally designed by the SAE for truck applications as a temporary means for the transmission to override engine speed during gearshifts, this PGN is now widely used as a permanent means of controlling the engine speed. It is particularly common in machines that have complex hydraulic systems. This is a powerful feature, but special care must be taken by the OEM with the implementation of TSC1 to ensure that the speed demanded of the engine is one that is safe and appropriate for the current operating conditions of the engine. It is the responsibility of the ECM to ensure that this is so and to perform the necessary risk assessment validation of the software of electronic modules on the application that are transmitting TSC1 speed demand messages to the engine. TSC1 Configuration Tsc1 will always be available (it does not need to be configured to be ENABLED in the service tool) In addition, Tsc1 may be configured to be a “continuous speed limit/ request”. In this case the
• TSC1 –Transient Engine Speed Limit / Request • TSC1 - Continuous Speed Limit / Request
Perkins Confidential Green Production January 07
Page 91 of 119 1104D and 1106DD Electronic Application and Installation Guide
In addition to these options, it is also possible to specify what droop value applies to the engine speed request. This will operate in the same was as for the direct analogue / PWM and throttle position switch inputs. TSC1 as Transient Speed Limit / Request The ECM will allow other modules to request or limit engine speed for any period. The TSC1 message will override any other speed demand such as PWM throttle pedal. End of Transmission – fault detection The ECM needs to differentiate between the end of a transmission by another controller and an intermittent failure. The ECM expects, therefore, that when a controller no longer wished to demand engine speed then it will terminate with at least one message with the control override bits set to 00. If the engine sees that TSC1 messages have stopped, for 90ms, but have not been terminated correctly then the ECM will recognize this as a fault and will not accept any speed demand requests for the remainder of the key cycle.TSC1 as Permanent speed demand Source address requirements The ECM will accept messages from modules with any source address (i.e. TSC1 messages do not necessarily have to be sent by the transmission). The destination address does have to be 00 for the messages to be accepted by the engine however. TSC1 as Continuous Speed Limit / Request If TSC1 is to be the primary means of controlling the engine speed or as a method of continuously limiting engine speed, then the ECM may be configured to raise a fault code if a valid Tsc1 message is not received by the time that engine speed reaches 500rpm of the keyswitch being turned on. This will allow for the normal start up time of other electronic modules. TSC1 - Feature Summary Table Function TSC1 –

Note A: The ECM does not prioritize or arbitrate between speed request or limits from more than one source and so this situation may result in erratic engine operation. The OEM must ensure that TSC1 messages are not sent from more than one source at a time. Note B: Support for the “Torque limiting” aspect of TSC1 has been added, although this may only be used for temporary conditions, such as during a gear change. Cab Message 1 (CM1) Identifier Rate

Note B: Percent load at current speed. Parameter is not accurate at low loads nor during transient conditions. Note C: When there is discrepancy between the pedal position and the idle validation switch position, then the Accelerator Pedal Low Idle Switch parameter will be transmitted as 102 (error) and the accelerator pedal position will be transmitted as FE16 (error). If however, a pedal is not configured, then it will be sent as not supported. This will apply to both accelerator 1 and accelerator 2. Note also that the name “accelerator pedal” is not always accurate for off highway machines. Accelerator pedal 1 refers to any pedal, lever or other device that uses either the Analogue 1 or PWM throttle 1 input. Likewise, Accelerator pedal position 2 refers to any device that uses the analogue throttle 2 input. Electronic Engine Controller 1 (EEC1) Identifier Rate

The machine designer can use the spare inputs of the ECM, therefore, as additional input channels for non engine systems Note B: Each of the switch inputs is transmitted as 00 if it the switch is open (or not connected) and 01 if it is closed. The 2 “SWB” inputs below are “switch to battery”, meaning that when battery voltage is applied to the pin then it will be “closed”. All the other switch inputs are switch to ground, which means that when an input is at ground potential it will be “closed” Note C: The analogue channels are scaled at 0.955Volts per bit with a 0.5V offset. For example a voltage of 2.5Voltages would be transmitted as (2.5volts – 0.5 v offset)/0.000955 volts/bit = 209410 or 82E16 Table of Input pins to SPN’s

This is not the same as the implementation for tier 2 product but the change has been implemented to make the parameter more relevant to customers who need to determine how far and how rapidly the engine is lugging back. One effect will be that in many applications where there are high parasitic loads, the engine speed will never actually reach it’s desired operating speed.

This PGN defines several points on the torque curve (rating) that is active in the engine. The values will change if a different torque curve is selected or to reflect if the engine is derating e.g. due to excessive engine temperature. Note A: As this PGN is more than 8 bytes long, it will always be transmitted via the transport protocol Note B: This PGN is sent every 5 seconds but also whenever there is a change in active torque limit map. Note C: Engine reference torque is the advertised bare engine torque of the highest “enabled” rating in the box. That is the highest rating that can be selected via mode switches or J1939, whilst the engine is running. Note D: As both point 2 and point 6 are supported, and Gain (Kp) of Endspeed Governor is not, the support of this message conforms to Engine Configuration Characteristic Mode 1 as described in the J1939-71 specification

X Not available 1111 C This PGN is used to describe the logical state of the throttle position switch input (also known as multi-position throttle switch). Note A: “intermediate speed not requested” state is not supported. Note however, that on most applications where throttle position switch is used, logical position 1 will be all four switches in the open position and will equate to engine idle. Note B: There are only 13 states available but 16 possible combinations of the 4 switch inputs. No known application has used more than 10 states however, or is expected to use more than 10 states in the future, so this is not envisaged that this will cause a problem. If 16 states are use then logical states 14, 15 and 16 will be transmitted as 13.

This PGN may be sent to the engine to demand an alternative rating or droop, in a similar way to the hardwired “mode switches”. The J1939 request will have precedence over the hard wired switch inputs to the ECM. When the ECM receives this PGN, it will switch to the alternate ratings/alternate droop settings requested. It will remain in this new state until either another message is received with a different ratin / droop request, or until the key switch is cycled Note A: Ratings 1 to n are populated with all the ratings available in the ECM with “1” being the lowest and “n” being the highest rating. If the ECM receives the “0” then the rating value entered through the mode selection switches should be used. Off highway Engine control selection state (OHCSS) Identifier Rate

If there is more than one fault code present then the DM1 message will be longer than 8 bytes thus the transport protocol (BAM) will be used to send the message. This is different from tier 2 functionality where the transport protocol is used to send all DM1 messages, even if only one fault code is active Note B: A DM1 message is sent when a new active fault is detected, and approximately every 1second after that. The DM1 message is not sent if there are no active fault codes. Note C: This is not supported as per J1939 – Implementation is supported as follows: Diagnostic and Event codes have been split into 3 categories of severity called “Warning Category Indicators (WCI)” .

The lowest level (Level 1) is used for “warning” level faults, such as when engine design limits for temperature have been reached, or for a sensor short circuit. The highest level (Level 3) is used for events where the severity merits the machine and the engine being immediately stopped. Level 2 is an intermediate level used particularly for events or diagnostic which cause an engine derate The status lamps in the DM1 message will be switched on according to the following table:

Diagnostic codes are those that relate to faults of the electronic system (e.g. sensor failure. Event codes are those where there is a problem with the engine operation (e.g. coolant temperature high warning) Event codes can only be cleared with the service tool and require a factory password.

Perkins Data Link For industrial engines, the Perkins Datalink (PDL) is principally used for service tool support. If an application does have a requirement to communicate with another system on PDL, for example with a Perkins transmission or a display, then please contact your local applications team for further information.
Other Datalink Standards
CANopen CANopen may become a popular choice of CAN higher level protocol in off-highway machines which use significant numbers of electro-hydraulic controllers. If CANopen is used as the main communications standard in a vehicle, then a J1939 gateway is required A specification for a CAN open to J1939 gateway may be obtained from the the website of “CAN in Automation (CIA)” .
OEM Proprietary CAN standards It is accepted that the J1939 standard cannot meet all the diverse needs of the many specialised applications in the off-highway market. The OEM may have to use a small number of proprietary messages on the same bus as the J1939 messages. If a large number of proprietary messages are required for an application, then the machine designer should consider the use of a CAN gateway to isolate the proprietary messages from the J1939 bus. The risk of OEM defined messages is that they will clash with some of the J1939 standard messages.

Appendix 2 - Electronic Options Selection Form The latest copy of this form is found in the Engine Sales Manual. It is replicated in this document for illustration and for convenience. At the time of customer order, the customer needs to make certain decisions about how the engine is configured. This configuration is done in the factory, although most items can also be adjusted in the field using the service tool.
