Foreword

Foreword

Recommended service should be performed at the

appropriate intervals as indicated in the Maintenance

Interval Schedule. The actual operating environment

of the engine also governs the Maintenance Interval

Schedule. Therefore, under extremely severe, dusty,

wet or freezing cold operating conditions, more

frequent lubrication and maintenance than is

specified in the Maintenance Interval Schedule may

be necessary.

Literature Information

This manual contains safety, operation instructions,

lubrication and maintenance information. This manual

should be stored in or near the engine area in a

literature holder or literature storage area. Read,

study and keep it with the literature and engine

Safety Section

General Hazard Information

•   The engine is stopped. Ensure that the engine

cannot be started.

•   Disconnect the batteries when maintenance is

performed or when the electrical system is

serviced. Disconnect the battery ground leads.

Tape the leads in order to help prevent sparks.

•   Do not attempt any repairs that are not

understood. Use the proper tools. Replace any

Pressurized Air and Water

Pressurized air and/or water can cause debris and/or

hot water to be blown out. This action could result in

personal injury.

Illustration 6

g00687600

Always use a board or cardboard when you check for

a leak. Leaking fluid that is under pressure can

penetrate body tissue. Fluid penetration can cause

serious injury and possible death. A pin hole leak can

cause severe injury. If fluid is injected into your skin,

you must get treatment immediately. Seek treatment

from a doctor that is familiar with this type of injury.

When pressurized air and/or pressurized water is

used for cleaning, wear protective clothing, protective

shoes, and eye protection. Eye protection includes

goggles or a protective face shield.

The maximum air pressure for cleaning purposes

must be below 205 kPa (30 psi). The maximum water

pressure for cleaning purposes must be below

275 kPa (40 psi).

Containing Fluid Spillage

Care must be taken to ensure that fluids are

contained during performance of inspection,

maintenance, testing, adjusting, and repair of the

product. Be prepared to collect the fluid with suitable

containers before opening any compartment or

disassembling any component containing fluids.

Fluid Penetration

Pressure can be trapped in the hydraulic circuit long

after the engine has been stopped. The pressure can

cause hydraulic fluid or items such as pipe plugs to

escape rapidly if the pressure is not relieved correctly.

Dispose of all fluids according to local regulations and

mandates.

Do not remove any hydraulic components or parts

until pressure has been relieved or personal injury

may occur. Do not disassemble any hydraulic

components or parts until pressure has been relieved

or personal injury may occur. Refer to the OEM

information for any procedures that are required to

relieve the hydraulic pressure.

Static Electricity Hazard when

Fueling with Ultra-low Sulfur Diesel

Fuel

The removal of sulfur and other compounds in ultra-

low sulfur diesel fuel (ULSD fuel) decreases the

conductivity of ULSD and increases the ability of

ULSD to store static charge. Refineries may have

treated the fuel with a static dissipating additive.

Many factors can reduce the effectiveness of the

additive over time. Static charges can build up in

ULSD fuel while the fuel is flowing through fuel

delivery systems. Static electricity discharge when

combustible vapors are present could result in a fire

or explosion. Ensure that the entire system used to

refuel your machine (fuel supply tank, transfer pump,

transfer hose, nozzle, and others) is properly

grounded and bonded. Consult with your fuel or fuel

system supplier to ensure that the delivery system

complies with fueling standards for proper grounding

and bonding.

General Hazard Information

•   Never use compressed air for cleaning.

•   Avoid brushing materials that contain asbestos.

•   Avoid grinding materials that contain asbestos.

Avoid static electricity risk when fueling. Ultra-low

sulfur diesel fuel (ULSD fuel) poses a greater stat-

ic ignition hazard than earlier diesel formulations

with a higher sulfur contents. Avoid death or seri-

ous  injury from  fire  or  explosion. Consult  with

your fuel or fuel system supplier to ensure the de-

livery system is in compliance with fueling stand-

ards for proper grounding and bonding practices.

•   Use a wet method in order to clean up asbestos

materials.

•   A vacuum cleaner that is equipped with a high

efficiency particulate air filter (HEPA) can also be

used.

Inhalation

•   Use exhaust ventilation on permanent machining

jobs.

•   Wear an approved respirator if there is no other

way to control the dust.

•   Comply with applicable rules and regulations for

the work place. In the United States, use

Occupational Safety and Health Administration

(OSHA) requirements. These OSHA requirements

can be found in “29 CFR 1910.1001”.

•   Obey environmental regulations for the disposal of

asbestos.

•   Stay away from areas that might have asbestos

particles in the air.

asbestos free. Perkins recommends the use of only

genuine Perkins replacement parts. Use the following

guidelines when you handle any replacement parts

that contain asbestos or when you handle asbestos

debris.

Illustration 8

g00706404

Use caution. Avoid inhaling dust that might be

generated when you handle components that contain

asbestos fibers. Inhaling this dust can be hazardous

to your health. The components that may contain

asbestos fibers are brake pads, brake bands, lining

material, clutch plates, and some gaskets. The

asbestos that is used in these components is usually

bound in a resin or sealed in some way. Normal

handling is not hazardous unless airborne dust that

contains asbestos is generated.

Improperly disposing of waste can threaten the

environment. Potentially harmful fluids should be

disposed of according to local regulations.

Always use leakproof containers when you drain

fluids. Do not pour waste onto the ground, down a

Electrical System

Start the engine from the operator compartment or

from the engine start switch.

Always start the engine according to the procedure

that is described in the Operation and Maintenance

Manual, “Engine Starting” topic in the Operation

Section. Knowing the correct procedure will help to

prevent major damage to the engine components.

Knowing the procedure will also help to prevent

personal injury.

Never disconnect any charging unit circuit or battery

circuit cable from the battery when the charging unit is

operating. A spark can cause the combustible gases

that are produced by some batteries to ignite.

To help prevent sparks from igniting combustible

gases that are produced by some batteries, the

negative  “−” jump-start cable should be connected

last from the external power source to the negative

“−”  terminal of the starting motor. If the starting motor

is not equipped with a negative “−” terminal, connect

the jump-start cable to the engine block.

To ensure that the jacket water heater (if equipped) is

working correctly, check the water temperature gauge

and/or the oil temperature gauge during the heater

operation.

Engine exhaust contains products of combustion

which can be harmful to your health. Always start the

engine and operate the engine in a ventilated area. If

the engine is started in an enclosed area, vent the

engine exhaust to the outside.

Check the electrical wires daily for wires that are

loose or frayed. Tighten all loose electrical wires

before the engine is started. Repair all frayed

electrical wires before the engine is started. Refer to

the Operation and Maintenance Manual, “Engine

Starting” for specific starting instructions.

Note: The engine may be equipped with a device for

cold starting. If the engine will be operated in cold

conditions, then an extra cold starting aid may be

required. Normally, the engine will be equipped with

the correct type of starting aid for your region of

operation.

Grounding Practices

Proper grounding for the engine electrical system is

necessary for optimum engine performance and

reliability. Improper grounding will result in

uncontrolled electrical circuit paths and in unreliable

electrical circuit paths.

Uncontrolled electrical circuit paths can result in

damage to main bearings, to crankshaft bearing

journal surfaces, and to aluminum components.

Safety Section

Engine Electronics

Engines that are installed without engine-to-frame

ground straps can be damaged by electrical

discharge.

The Engine Monitoring package can vary for different

engine models and different engine applications.

However, the monitoring system and the engine

monitoring control will be similar for all engines.

To ensure that the engine and the engine electrical

systems function properly, an engine-to-frame ground

strap with a direct path to the battery must be used.

This path may be provided by way of a starting motor

ground, a starting motor ground to the frame, or a

direct engine ground to the frame.

Note: Many of the engine control systems and

display modules that are available for Perkins

Engines will work in unison with the Engine

Monitoring System. Together, the two controls will

provide the engine monitoring function for the specific

engine application. Refer to the Troubleshooting

manual for more information.

All grounds should be tight and free of corrosion. The

engine alternator must be grounded to the negative

“-” battery terminal with a wire that is adequate to

handle the full charging current of the alternator.

Engine Electronics

Tampering with the electronic system installation

or the OEM  wiring installation can be dangerous

and could result in personal injury or death and/or

engine damage.

This engine has a comprehensive, programmable

Engine Monitoring System. The Electronic Control

Module (ECM) will monitor the engine operating

conditions. If any of the engine parameters extend

outside an allowable range, the ECM will initiate an

immediate action.

The following actions are available for engine

monitoring control: WARNING, DERATE and

SHUTDOWN. These engine monitoring modes can

limit engine speed and/or the engine power.

Many of the parameters that are monitored by the

ECM can be programmed for the engine monitoring

functions. The following parameters can be monitored

as a part of the Engine Monitoring System:

•   Operating Altitude

•   Engine Coolant Level

•   Engine Coolant Temperature

General Information

Product Description

An electronic governor controls the output of the unit

injectors in order to maintain the engine rpm that is

desired. The functions of the governor include a

programmable low idle and a 20 rpm to 200 rpm

governor overrun.

High injection pressures are produced by

electronically controlled, mechanically actuated unit

injectors. The injectors combine the pumping and the

electronic fuel metering (duration and timing) during

injection. The unit injectors accurately control smoke

limiting, white smoke, and engine acceleration rates.

There is one unit injector per cylinder. Individual unit

injectors meter the fuel. The individual unit injectors

also pump the fuel. The metering and the pumping is

done under high pressure. High injection pressures

help to reduce fuel consumption and emissions. The

use of this type of unit injector provides total

electronic control of injection timing. The injection

timing varies with engine operating conditions. The

engine performance is optimized in the following

areas:

Electronic Engine Features

The engine is designed for electronic controls. The

integral on board computer controls the operation of

the engine. Current operating conditions are

monitored. The Electronic Control Module (ECM)

controls the response of the engine to these

conditions and to the demands of the operator. These

conditions and operator demands determine the

precise control of fuel injection by the ECM. The

electronic engine control system provides the

following features:

The cooling system consists of the following items: a

centrifugal pump that is driven by a gear, water

temperature regulator, an oil cooler and a radiator that

incorporates a shunt system.

•   Engine speed governor

•   Automatic air/fuel ratio control

•   Torque rise shaping

The engine lubricating oil is supplied by a gear type

pump. The engine lubricating oil is cooled and

filtered. Bypass valves provide unrestricted flow of

lubrication oil to the engine in the following

circumstances: when the oil viscosity is high and if

the oil cooler or the oil filter elements (paper

cartridge) become plugged.

•   Injection timing control

including the use of recommended fuels, coolants,

and lubrication oils.

Additional Features

The following additional features provide increased

engine fuel economy and serviceability:

•   Cold starting capability

•   Diagnostics

Engine Service Life

Engine efficiency and maximum utilization of engine

performance depend on the adherence to proper

operation and maintenance recommendations. In

addition, use recommended fuels, coolants, and

lubricants. Use the Operation and Maintenance

Manual as a guide for required engine maintenance.

Expected engine life is predicted by the average

power that is demanded. The average power that is

demanded is based on fuel consumption of the

engine over a time. Reduced hours of operation at full

throttle and/or operating at reduced throttle settings

result in a lower average power demand. Reduced

hours of operation will increase the length of

operating time before an engine overhaul is required.

Monitoring System

Features and Controls

If the engin, e is in the Warning condition, then the

event will be logged in the memory of the ECM. An

event code will be transmitted over the Perkins Data

link and the hard wired Warning output will be

energized. If the engine is in the Warning condition,

the event code and output will remain while the

condition exists. The electronic service tool is used to

remove the event code from the memory of the ECM.

The trip point for the Warning alarm will be set to a

factory default in production. The electronic service

tool may be used to alter the trip point for a Warning

within predefined limits.

i06216788

Monitoring System

The monitoring system is designed to alert the

operator to an immediate problem.

The engine has protection in three stages:

•   Warning

Action Alert

The Action Alert informs the OEM that the engine is

approaching a critical condition. The engine should

be stopped in a controlled manner. Further running of

the engine may result in an immediate shutdown.

•   Action Alert

•   Shutdown

The engine protection may be overridden by the

critical condition mode.

If the engine is in the Action Alert condition, the event

will be logged in the memory of the ECM. An event

code will be transmitted over the Perkins Data link

and the hard wired Action Alert will be energized. If

the engine is in the Action Alert condition, the event

code and output will remain while the condition exists.

The event code cannot be cleared from the memory

of the ECM without using a factory password.

The Electronic Control Module (ECM) monitors the

following parameters:

•   Engine Temperatures

•   Engine Pressures

•   Engine Speed

Shutdown

If the engine reaches the Shutdown condition, one of

the following events has occurred: low lubricating oil

pressure, high coolant temperature, or overspeed.

The event will be logged in the memory of the ECM.

The engine will be shut down. An event code will be

transmitted over the Perkins  Data link and the hard

wired Shutdown output will be energized. The

Shutdown condition will latch until the ECM is reset.

The event code for the shutdown cannot be cleared

from the memory of the ECM without using a factory

password.

If the parameters exceed a trip point for a period that

is longer than the delay period, the ECM logs an

event code. The indicator switches to the ON

position.

The following parameters are monitored for event

codes:

•   Lubricating Oil Pressure

•   Coolant Temperature

•   Overspeed

Critical Protection Override

In an application that is critical for safety, the

protection system can be overridden in order to

ensure continued engine operation during fault

conditions.

•   Intake Manifold Temperature

•   Intake Manifold Pressure

•   Fuel Temperature

Critical Protection Override will be set by a switch

input from the OEM. For example, switch to battery +

in order to disable a critical override. Critical

Protection Override input can be enabled in the

electronic service tool by use of a factory password.

The temperature protection is disabled for a period

when the engine is cranking in order to compensate

for heat soak solutions.

The ECM has dedicated alarm outputs for each of the

three stages of protection. There are also dedicated

alarm outputs for oil pressure, coolant temperature,

and overspeed events which are energized at any

stage of protection.

When the Critical Protection Override feature is

active, the ECM will continue to run the engine in all

shutdown conditions except for Overspeed shutdown.

If the shutdown is overridden, an event code is

generated. The ECM will log the event code. The

ECM will energize the following: Warning, Action

Alert, Shutdown, oil pressure, coolant temperature

and overspeed outputs as normal. The warranty of

the engine will be invalidated if the engine is operated

in the following conditions: active event code and

Critical Protection Override mode.

Features and Controls

Sensors and Electrical Components

Standard Warning Outputs

The following sensors are monitored in order to

determine if the sensors are out of the normal range,

an open circuit, or a short circuit:

The ECM provides individual outputs in order to drive

warning lamps or relays to indicate each of the

following fault conditions:

•   Atmosphere Pressure

•   Lubricating Oil Pressure

•   Inlet Manifold Pressure

•   Inlet Manifold Temperature

•   Fuel Temperature

•   Diagnostic Fault

•   Oil Pressure

•   Coolant Temperature

•   Overspeed

•   Action Alert

•   Coolant Temperature

•   Engine Speed

•   Warning

•   Shutdown

•   Desired Speed Input

If the ECM detects a coolant temperature warning,

the warning output will be energized. If the ECM

detects a warning for low oil pressure, the warning

output will be energized.

The Diagnostic output differs from the Warning and

Shutdown outputs. The Warning and Shutdown

outputs refer to the operation of the engine. The

Diagnostic output refers to the condition of the

electronic system and software system.

If the Action Alert alarms are enabled and the ECM

detects a coolant temperature condition, the output

on the Action Alert will be energized.

A diagnostic fault may develop on the lubricating oil

pressure or coolant temperature sensors. For

example, if a Shutdown protection sensor has a fault,

the result will be an engine shutdown, unless the

system is in critical protection override. If a diagnostic

fault occurs, with one of the engine speed sensors

while the engine is running. The engine continues to

run by using the other timing sensor for reference.

If the engine shuts down on low oil pressure, the

output on the shutdown will be energized. If the

engine shuts down on coolant temperature, or the

engine shuts down on overspeed, the shutdown

output will be energized.

Shutdown Reset

i06216799

The cause of an engine shutdown must be

investigated. Corrective action must be taken before

the system is reset in order to operate the engine.

Sensors and Electrical

Components

After an engine shutdown, operate the reset input of

the ECM or power down the controller.

The illustrations within the following sections are

typical location of the sensors or electrical

components for an industrial engine. Specific engines

may appear different due to differences in

applications.

Powering down the electronic control module can be

achieved by the operation of the keyswitch into sleep

mode. The electronic control module can be powered

down by isolating the power supply to the electronic

control module.

Note: The ECM cannot be reset by using the Reset

input until the engine has stopped.

Diagnostic

If there is a fault with an engine protection sensor on

the engine, the engine activates a diagnostic code.

The engine communicates the diagnostic code to the

operator via the Diagnostic output. The diagnostic

code provides an indication to the operator of a fault

with the engine protection system. Running of the

engine for a prolonged period in this condition may

result in engine failure. The output is normally used to

drive lamps or relays.

there is a low oil pressure condition, engine power will

be limited until the problem is corrected. If the oil

pressure is within the normal range, the engine may

be operated at the rated speed and load. However,

maintenance should be performed as soon as

possible.

The problems may have been repaired since the

logging of the code. These codes do not indicate that

a repair is needed. The codes are guides or signals

when a situation exists. Codes may be helpful to

troubleshoot problems.

When the problems have been corrected, the

corresponding logged fault codes should be cleared.

The active diagnostic code should be investigated.

The cause of the problem should be corrected as

soon as possible. If the cause of the active diagnostic

code is repaired and there is only one active

i06217559

diagnostic code, the diagnostic lamp will turn off.

Diagnostic Lamp

Operation of the engine and performance of the

engine can be limited as a result of the active

diagnostic code that is generated. Acceleration rates

may be lower. Refer to the Troubleshooting Guide for

more information on the relationship between these

active diagnostic codes and engine performance.

A diagnostic lamp is used to indicate the existence of

an active fault. A fault diagnostic code will remain

active until the problem is repaired. The diagnostic

code may be retrieved by using the electronic service

tool.
