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

information.

The maintenance schedule items are organized for

a preventive maintenance management program. If

the preventive maintenance program is followed, a

periodic tune-up is not required. The implementation

of a preventive maintenance management program

should minimize operating  costs through cost

avoidances resulting from reductions in unscheduled

downtime and failures.

English is the primary  language for all Perkins

publications. The English used facilitates translation

and consistency.

Some photographs or illustrations in this  manual

show details or attachments that may be different

from your engine. Guards and  covers may have

been removed for illustrative purposes. Continuing

improvement and advancement of product design

may have caused changes to your engine which are

not included in this manual. Whenever a question

arises regarding your engine, or this manual, please

consult with your Perkins dealer  or your Perkins

distributor for the latest available information.

Maintenance Intervals

Perform maintenance on items  at multiples of

the original requirement. We recommend that the

maintenance schedules be reproduced and displayed

near the engine as a convenient reminder. We also

recommend that a maintenance record be maintained

as part of the engine’s permanent record.

Burn Prevention

Coolant

When the engine is at operating temperature, the

engine coolant is hot. The  coolant is also under

pressure. The radiator and all lines to the heaters or

to the engine contain hot coolant. Any contact with

hot coolant or with steam can cause severe burns.

Allow cooling system components to cool before the

cooling system is drained.

Check the coolant level after the engine has stopped

and the engine has been allowed to  cool. Ensure

that the filler cap is cool before removing  the filler

cap. The filler cap must be cool enough to touch with

a bare hand. Remove the filler cap slowly in order

to relieve pressure.

g00687600

Illustration 5

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.

Cooling system conditioner contains alkali. Alkali can

cause personal injury. Do not allow alkali to contact

the skin, the eyes, or the mouth.

Oils

Hot oil and hot lubricating components can cause

personal injury. Do not allow hot oil or hot components

to contact the skin.

Containing Fluid Spillage

Care must be taken in order  to ensure that fluids

are contained during performance of  inspection,

maintenance, testing, adjusting and repair of  the

engine. Make provision to collect  the fluid with a

suitable container before any compartment is opened

or before any component is disassembled.

If the application has a makeup tank, remove the cap

for the makeup tank after the engine has stopped.

The filler cap must be cool to the touch.

Batteries

The liquid in a battery is an electrolyte. Electrolyte is

an acid that can cause personal injury. Do not allow

electrolyte to contact the skin or the eyes.

•  Only use the tools that are suitable for collecting

fluids and equipment that is suitable for collecting

fluids.

Do not smoke while checking the battery electrolyte

levels. Batteries give off flammable fumes which can

explode.

•  Only use the tools that are suitable for containing

fluids and equipment that is suitable for containing

fluids.

Always wear protective glasses when you work with

batteries. Wash hands after touching batteries. The

use of gloves is recommended.

with the correct type of starting aid for your region

of operation.

Grounding Practice

i01462046

Engine Stopping

Stop the engine according  to the procedure in

the Operation and Maintenance Manual, “Engine

Stopping (Operation Section)” in order  to avoid

overheating of the engine and accelerated wear of

the engine components.

Use the Emergency Stop Button (if equipped) ONLY

in an emergency situation. Do not use the Emergency

Stop Button for normal engine stopping.  After an

emergency stop, DO NOT start the engine until the

problem that caused the emergency stop has been

corrected.

g01403749

Illustration 9

Typical example

Stop the engine if an overspeed condition  occurs

during the initial start-up of a new engine or an engine

that has been overhauled. This may be accomplished

by shutting off the fuel supply to the engine and/or

shutting off the air supply to the engine.

(1) Starting motor to engine block

(2) Starting motor to battery negative

Correct grounding for the engine electrical system

is necessary for optimum  engine performance

and reliability. Incorrect grounding  will result in

uncontrolled electrical circuit paths and in unreliable

electrical circuit paths.

To stop an electronically controlled engine, cut the

power to the engine.

Uncontrolled electrical circuit paths can  result in

damage to the crankshaft bearing journal surfaces

and to aluminum components.

i02814681

Electrical System

Engines that are installed without engine-to-frame

ground straps can  be damaged by electrical

discharge.

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 ensure that the engine and the engine electrical

systems function correctly, 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 direct

engine ground to the frame.

To help prevent sparks from igniting  combustible

gases that are produced by  some batteries, the

negative “−” 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

cable to the engine block.

The connections for the 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

The power supply connections  and the ground

connections for the engine electronics should always

be from the isolator to the battery.

i02773399

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  Engine Control

Module (ECM) has the ability to 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, ACTION ALERT, and

SHUTDOWN.

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:

•  Atmospheric Pressure

•  Intake Manifold Air Pressure

•  Coolant Temperature

•  Engine Oil Pressure

•  Crankshaft Position

•  Camshaft Position

•  Fuel Temperature

•  Intake Manifold Temperature

•  System Voltage

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.

Model Views

Very 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.

Engine efficiency, efficiency of emission controls, and

engine performance depend on adherence to proper

operation and maintenance recommendations. This

includes the use of recommended fuels, coolants

and lubrication oils.

Aftermarket Products and Perkins

Engines

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:

When auxiliary devices, accessories, or consumables

(filters, additives, catalysts, etc) which are made by

other manufacturers are used on Perkins products,

the Perkins warranty is not affected simply because

of such use.

However, failures that result from the installation

or use  of other manufacturers’ devices,

accessories, or consumables are NOT Perkins

defects. Therefore, the defects are NOT covered

under the Perkins warranty.

•  Starting

•  Emissions

•  Noise

•  Fuel consumption

The timing advance is achieved  through precise

control of the  injector firing. Engine speed  is

controlled by adjusting the  firing duration. The

information is provided to the  Electronic Control

Module (ECM) by the crankshaft position sensor and

the camshaft position sensor. The information is for

detection of cylinder position and engine speed.

The engines have built-in diagnostics  in order to

ensure that all of the components are functioning

and operating properly. In the  event of a system

component deviation from the programmed limits,

the operator will be alerted  to the condition by a

DIAGNOSTIC lamp that is mounted on the control

panel. An electronic service tool that is provided by

Perkins may be used to read the diagnostic codes.

These codes are logged and stored  in the ECM.

Refer to Operation and Maintenance Manual, “Engine

Diagnostics” for additional information.

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.

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  parts when the oil

viscosity is high or if either the oil  cooler or the oil

filter elements (paper cartridge) become plugged.

for information on engine storage.

i02513632

Product Lifting

There is three different levels  of engine storage.

Level “A, B and C”.

Level “A ”

Level “A” will give protection for 12 month for diesel

engines and 12 month protection for gas engines.

This is for engines that are transported by a container

or a truck. Level “A” is for the transportation of items

that are within the United kingdom and within Europe.

Level “B ”

This level is additional to level “A”.  Level “B ” will

give protection under normal  storage condition

from −15° to  +55°C (5° to  99°F) and “90%”

relative humidity for two year. Level  “B” is for the

transportation of items overseas.

g00103219

Illustration 16

NOTICE

Level “C ”

Never bend the eyebolts and the brackets. Only load

the eyebolts and the brackets under tension. Remem-

ber that the capacity of an eyebolt is less as the angle

between the supporting members and  the object be-

comes less than 90 degrees.

In order to protect the product to Level “C”, contact

Perkins Engines Company Limited Stafford.

When it  is necessary to  remove a component at  an

angle, only use a link bracket that is properly rated for

the weight.

Use a hoist to  remove heavy components. Use

an adjustable lifting beam  to lift the engine. All

supporting members (chains and cables) should be

parallel to each other. The chains and cables should

be perpendicular to the top of the object that is being

lifted.

Some removals require lifting the fixtures in order to

obtain proper balance and safety.

To remove the engine ONLY, use the lifting eyes that

are on the engine.

Lifting eyes are designed and installed for specific

engine arrangements. Alterations to the lifting eyes

and/or the engine make the lifting eyes and the lifting

fixtures obsolete. If alterations are made,  ensure

that proper lifting devices are provided. Consult your

Perkins dealer for information regarding fixtures for

proper engine lifting.

Features and Controls

Features and Controls

Warning Alarm

The Warning alarm informs the user that the engine

is approaching a critical condition.

i02780670

Monitoring System

If the engine is in the Warning condition,  then the

event will be logged in  the memory of the ECM.

A 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.

The engine has protection in three stages:

•  Warning

•  Action Alert

•  Shutdown

The engine protection may be overridden  by the

critical condition mode.

Action Alert

The Electronic Control Module (ECM) monitors the

following parameters:

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.

•  Engine Temperatures

•  Engine Pressures

•  Engine Speed

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

will be logged in the memory of the ECM. A  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 can not be cleared from the memory

of the ECM without using a factory password.

If the parameters exceed a trip point for a period of

time that is longer than the delay period, the ECM

logs an event code and the indicator switches ON.

The following parameters are monitored for event

codes:

Shutdown

•  Lubricating Oil Pressure

•  Coolant Temperature

•  Overspeed

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. A 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 can not be cleared

from the memory of the ECM without using a factory

password.

•  Intake Manifold Temperature

•  Intake Manifold Pressure

•  Fuel Temperature

The temperature protection is disabled for a period

of time when the  engine is cranking in order to

compensate for heat soak solutions.

Critical Protection Override

If the engine is in an application  that is critical for

safety, the protection system can be overridden in

order to ensure the continuation of the power supply

during engine fault conditions.

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.

SEBU8337

Operation Section

Features and Controls

Shutdown Reset

Critical Protection Override will be set by a switch

input from the OEM.  For example, this may be

a 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 cause of  an engine shutdown  must be

investigated. Corrective action must be taken before

the system is reset in order to operate the engine.

After an engine shutdown, operate the reset input of

the ECM or power down the controller.

When the Critical Protection Override  feature is

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

shutdown conditions with the exception of Overspeed

shutdown. If the shutdown is overridden a 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.

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: It is not possible to reset the ECM by using the

Reset input until the engine has come to rest.

Altitude derate

Standard Warning Outputs

At high altitudes or high ambient temperatures, the

engine will be derated. The engine derate information

can be obtained from the Applications Department at

Perkins Engines Company Limited Stafford.

The ECM provides individual outputs  in order to

drive warning lamps or relays to indicate each of the

following fault conditions:

•  Diagnostic Fault

•  Oil Pressure

•  Coolant Temperature

•  Overspeed

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 generally used

to drive lamps or relays.

•  Action Alert

•  Warning

•  Shutdown

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:

If the ECM  detects a warning for  the coolant

temperature , the output on the coolant temperature

will be energized and the  warning output will be

energized. If the ECM detects a warning for the low

oil pressure, the output on the oil pressure  will be

energized and the warning output will be energized.

•  Atmosphere Pressure

•  Lubricating Oil Pressure

•  Inlet Manifold Pressure

•  Inlet Manifold Temperature

•  Fuel Temperature

If the Action Alert alarms are enabled and the ECM

detects a coolant temperature condition, the output

on the coolant Temperature will be energized and the

output on the Action Alert will be energized.

If the engine shuts down  on low oil pressure the

output on the low oil pressure will be energized and

the output on the shutdown will be energized. If the

engine shuts down on coolant temperature or the

engine shuts down on overspeed  the dedicated

output and the shutdown output will be energized.

•  Coolant Temperature

•  Engine Speed

•  Desired Speed Input

Operation Section

Features and Controls

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.

A diagnostic fault may develop on  the lubricating

oil pressure or coolant temperature sensors.  For

example, if a Shutdown protection sensor has a fault,

this will result in 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.

Failure of Sensors

Programmable Monitoring System

(PMS)

All Sensors

The Programmable Monitoring System determines

the level of action that is taken by the Engine Control

Module (ECM) in response to a condition that can

damage the engine. These conditions are identified

by the ECM from the signals that are produced from

the following sensors.

A failure of any of the sensors may be caused by one

of the following malfunctions:

•  Sensor output is open.

•  Sensor output is shorted to “- battery” or “+ battery”.

Engine Coolant Temperature

Sensor 1

•  Measured reading of the  sensor is out of the

specification.

The coolant temperature sensor monitors engine

coolant temperature. The output of the  ECM can

indicate a high coolant temperature through a relay

or a lamp. The coolant temperature sensor is used

by the ECM to determine initiation of the Cold Start

Condition.

Operation Section

Features and Controls

Failure of the  Coolant Temperature

Sensor

Low Oil Pressure Warning

The setpoint for  the low pressure warning  is

dependent upon the engine speed. The fault will be

active and logged only if the engine has been running

for more than 8 seconds.

The ECM will  detect a failure  of the coolant

temperature sensor. The  diagnostic lamp will

warn the operator about the status of  the coolant

temperature sensor. A  failure of the coolant

temperature sensor will cause a shutdown of  the

engine. The faulty sensor should be replaced. Refer

to Disassembly and Assembly Manual,  “Coolant

Temperature Sensor - Remove and Install”.

Low Oil Pressure

The very low oil pressure setpoint is dependent upon

the engine speed. If very low oil pressure is detected,

the ECM will stop the engine immediately  unless

Critical Events Override is active.

Intake Manifold Pressure Sensor 2

Failure of the Engine Oil Pressure Sensor

The intake manifold pressure sensor measures boost

pressure in the intake manifold. A signal is sent to the

ECM. A failure of the inlet manifold pressure sensor

will limit the power of the engine.

The ECM will detect failure of the engine oil pressure

sensor. The diagnostic lamp warns the user about the

status of the engine oil pressure sensor. The engine

oil pressure related strategies will be disabled in the

event of a failure of the engine oil pressure sensor.

A failure of the engine oil pressure sensor will cause

a shutdown of the engine. The faulty sensor should

be replaced. Refer to Disassembly and assembly

Manual, “Engine Oil Pressure Sensor - Remove and

Install”.

Intake Manifold Air Temperature

Sensor 3

The Intake manifold air temperature sensor measures

the intake air temperature. A signal  is sent to the

ECM. The intake manifold air temperature sensor is

also used by the ECM to determine initiation of the

Cold Start Strategy.

Fuel Temperature Sensor 7

Atmospheric Pressure Sensor 4

The fuel temperature sensor  monitors the fuel

temperature. The signal from the  sensor allows

the ECM to compensate for  changes in the fuel

temperature by adjusting the fuel rate for constant

power.

All the output signals from the pressure sensors are

matched to the output signal  of the atmospheric

pressure sensor during calibration. The signal from

the atmospheric pressure sensor is used by the ECM

in order to determine the operating altitude  of the

engine. If necessary, the ECM can derate the engine.

Primary Speed/Timing Sensor 8

If the ECM does not receive a signal from the primary

speed/timing sensor , the “DIAGNOSTIC” lamp will

indicate a diagnostic fault code which will be logged

in the ECM memory.

Secondary Speed/Timing Sensor 5

The signal from the secondary speed/timing sensor

is used by the ECM on engine start-up  in order to

determine the stroke that the pistons are on.  The

secondary speed/timing sensor may be used by the

ECM in order to operate the engine  if the primary

speed/timing sensor is faulty.

If the ECM does not receive a signal from the primary

speed/timing sensor (9), the ECM will read the signal

from the secondary speed/timing sensor (2). The

ECM continually checks in order  to determine if

there is a signal from both sensors. If either sensor

fails, the faulty sensor should be replaced. Refer to

Disassembly and Assembly Manual, “Crankshaft

Position Sensor - Remove and Install” or  refer to

Disassembly and Assembly Manual,  “Camshaft

Position Sensor - Remove and Install”.

In order to check the correct operation of the sensor,

refer to Troubleshooting, “Engine speed/Timing

sensor-Test”.

Engine Oil Pressure Sensor 6

Intermittent failure of the sensors will cause erratic

engine control.

The engine oil pressure  sensor is an absolute

pressure sensor that  measures the engine oil

pressure in the main  oil gallery. The engine oil

pressure sensor detects engine oil  pressure for

diagnostic purposes. The engine oil pressure sensor

sends a signal to the ECM .
