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

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

equipment that is damaged or repair the

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.

in an emergency situation. Do not use the Emergency

Stop Button for normal engine stopping. After an

emergency stop, DO NOTstart the engine until the

problem that caused the emergency stop has been

corrected.

Do not use aerosol types of starting aids such as

ether. Such use  could result in an explosion and

personal injury.

Stop the engine if an overspeed condition occurs

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

that has been overhauled. Stopping the engine may

be accomplished by shutting off the fuel supply to the

engine and/or shutting off the air supply to the engine.

If a warning tag is attached to the engine start switch

or to the controls, DO NOTstart the engine or move

the controls. Consult with the person that attached

the warning tag before the engine is started.

To stop an electronically controlled engine, cut the

power to the engine.

All protective guards and all protective covers must

be installed if the engine must be started in order to

perform service procedures. To help prevent an

accident that is caused by parts in rotation, work

around the parts carefully.

i06214263

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

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:

Features and Controls

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.

Warning Alarm

The Warning alarm informs the user that the engine is

approaching a critical condition.

SEBU9074

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.

Fault Logging

i06217555

Self-Diagnostics

The system provides the capability of Fault Logging.

When the Electronic Control Module (ECM)

generates an active diagnostic code, the code will be

logged in the memory of the ECM. The codes that

have been logged by the ECM can be identified by

the electronic service tool. The active codes that have

been logged will be cleared when the fault has been

rectified or the fault is no longer active. The following

logged faults cannot be cleared from the memory of

the ECM without using a factory password:

Perkins Electronic Engines can perform a self-

diagnostics test. When the system detects an active

problem, a diagnostic lamp is activated. Diagnostic

codes will be stored in permanent memory in the

Electronic Control Module (ECM). The diagnostic

codes can be retrieved by using the Perkins

Electronic Service Tool (EST).

Overspeed, low engine oil pressure, high engine

coolant temperature, and aftertreatment codes.

Some installations have electronic displays that

provide direct readouts of the engine diagnostic

codes. Refer to the manual that is provided by the

OEM for more information on retrieving engine

diagnostic codes.

i06217575

Engine Operation with Active

Diagnostic Codes

Active codes represent problems that currently exist.

These problems should be investigated first.

Logged codes represent the following items:

•   Intermittent problems

If a diagnostic lamp illuminates during normal engine

operation, the system has identified a situation that is

not within the specification. Use electronic service

tools to check the active diagnostic codes.

•   Recorded events

•   Performance history

Note: If the customer has selected  “DERATE”  and

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.
