Welding Precaution

Correct welding procedures are necessary in order to

avoid damage to the following components:

•  Electronic Control Module (ECM) on the engine

•  Clean Emissions Module (CEM)

•  Sensors

g01143634

Illustration 1

•  Associated components

Service welding guide (typical diagram)

Components for the driven equipment should also be

considered. When possible, remove the component

that requires welding. When welding on an engine

that is equipped with an ECM and  removal of the

component is not possible, the following procedure

must be followed. This procedure minimizes the risk

to the electronic components.

5.  When possible, connect the ground clamp for

the welding equipment directly  to the engine

component that will be welded. Place the clamp

as close as possible to the weld. Close positioning

reduces the risk of welding current damage to the

engine bearings, to the electrical components,

and to other components.

1.  Stop the engine. Remove the electrical power

from the ECM.

6.  Protect the wiring harnesses from welding debris

and/or from welding spatter.

2.  Ensure that the fuel supply to the engine is turned

off.

7.  Use standard welding procedures to weld the

materials together.

3.  Disconnect the negative battery cable from the

battery. If a battery disconnect switch is installed,

open the switch.

System Operation

Engine Governor

The ECM governs the engine. The ECM determines

the timing, the injection pressure, and the amount

of fuel that is delivered  to each cylinder. These

factors are based on the actual conditions and on the

desired conditions at any given time during starting

and operation.

The governor uses the throttle position sensor  to

determine the desired engine speed. The governor

compares the desired engine speed to the  actual

engine speed. The actual engine speed is determined

through interpretation of the signals that are received

by the ECM from the engine speed/timing sensors. If

the desired engine speed is greater than the actual

engine speed, the governor injects more fuel in order

to increase engine speed.

Troubleshooting Section

Fuel Injection

The ECM sends a high voltage signal to the injector

solenoids in order to energize  the solenoids. By

controlling the timing and the duration of  the high

voltage signal, the ECM can control the  following

aspects of injection:

•  Injection timing

•  Fuel delivery

The flash file inside the ECM  establishes certain

limits on the amount of fuel  that can be injected.

The FRC Fuel Limit is a limit that  is based on the

intake manifold pressure. The FRC Fuel Limit is used

to control the air/fuel ratio for control of emissions.

When the ECM senses a  higher intake manifold

pressure, the ECM increases the FRC Fuel Limit. A

higher intake manifold pressure indicates that there

is more air in the cylinder. When the ECM increases

the FRC Fuel Limit, the ECM allows more fuel into

the cylinder.

g01860934

Illustration 6

Typical example

The Rated Fuel Limit is a limit that is based on the

power rating of the engine and on the engine rpm.

The Rated Fuel Limit is like the rack stops and the

torque spring on a mechanically governed engine.

The Rated Fuel Limit provides  the power curves

and the torque curves for a specific engine  family

and a specific engine rating. All of these limits are

determined at the factory. These limits cannot  be

changed.

The desired engine speed is typically determined by

one of the following conditions:

•  The position of the throttle

•  The desired engine speed in Power Take-Off (PTO)

Timing Considerations

Once the governor has determined the amount of

fuel that is required, the governor must determine

the timing of the fuel injection. Fuel injection timing is

determined by the ECM after considering input from

the following components:

Customer Parameters and Engine Speed

Governing

A unique feature with electronic engines is customer

specified parameters. These parameters allow the

owner of the machine to fine-tune the ECM for engine

operation. Fine-tuning the ECM allows the machine

owner to accommodate the typical  usage of the

machine and the power train of the machine.

•  Coolant temperature sensor

•  Intake manifold air temperature sensor

•  Intake manifold pressure sensor

•  Barometric pressure sensor

Many of the customer parameters provide additional

restrictions on the actions that will be performed by

the ECM in response to input from the operator. The

PTO Top Engine Limit is an engine rpm limit that is

used by the ECM to limit the fuel during operation of

the PTO. The ECM will not fuel the injectors above

this rpm.

The ECM adjusts  timing for optimum engine

performance and fuel economy. Actual timing and

desired timing cannot be viewed with the electronic

service tool. The ECM determines the  location of

top center of the  number one cylinder from the

signals that are provided by the engine speed/timing

sensors. The ECM determines when injection should

occur relative to top center position. The ECM then

provides the signal to the injector at the desired time.

Some parameters are intended to notify the operator

of potential engine damage  (engine monitoring

parameters). Some parameters  enhance fuel

economy (machine speed, engine  speed limit,

and idle shutdown). Other parameters are used to

enhance the engine installation into the machine.

Other parameters are used to  provide operating

information to the owner of the machine.

Other ECM  Functions for

Performance

“Lifetime Total Engine Revolutions”  is the total

number of revolutions that have been completed by

the engine crankshaft.

The ECM can also provide enhanced control of the

engine for machine functions such as controlling the

cooling fan. Refer to Troubleshooting, “Configuration

Parameters” for supplemental information about the

systems that can be monitored by the ECM in order

to provide enhanced machine performance,  fuel

economy, and convenience for the operator.

“Average Load Factor” provides  relative engine

operating information. “Average  Load Factor”

compares actual operating information of the engine

to the maximum engine operation that is available.

“Average Load Factor” is determined by using “Total

Max Fuel”, “Total Idle Fuel”, and “Total Fuel”. All of

these parameters are available with the electronic

service tool. These parameters are available within

the menu for “Current Totals”.

ECM Lifetime Totals

The ECM maintains total data of the engine for the

following parameters:

Programmable Parameters

Certain parameters that affect engine  operation

may be changed with the electronic  service tool.

The parameters are stored in  the ECM, and the

parameters are protected from unauthorized changes

by passwords. These parameters are either system

configuration parameters or customer parameters.

•  “Total Operating Hours”

•  “Engine Lifetime Hours”

•  “Total Idle Time”

•  “Total Idle Fuel”

System configuration parameters are  set at the

factory. System configuration parameters  affect

emissions or power ratings within an engine family.

Factory passwords must be obtained and factory

passwords must be used  to change the system

configuration parameters.

•  “Total Fuel”

•  “Total Max Fuel”

•  “Engine Starts”

Customer parameters are  variable. Customer

parameters affect the following characteristics within

the limits that are set by the factory, by the monitoring

system, and by PTO operation:

•  “Lifetime Total Engine Revolutions”

•  “Average Load Factor”

The “Total Operating Hours” is the operating hours of

the engine. The operating hours do not include the

time when the ECM is powered but the engine is not

running.

•  Rpm ratings

•  Power ratings

Customer passwords may be required to change

customer specified parameters.

The “Engine Lifetime Hours” is the number of hours

when electrical power has  been applied to the

engine. These hours will include the time when the

ECM is powered but the engine is not running.

Some of the parameters may affect engine operation

in an unusual way. An operator might  not expect

this type of  effect. Without adequate training,

these parameters may lead to power  complaints

or performance complaints  even though the

performance of the engine is to the specification.

“Total Idle Time” and “Total Idle Fuel” can  include

operating time when the engine  is not operating

under a load.

Fuel Information can be displayed in US gallons or

in liters.

Refer to Troubleshooting, “Configuration Parameters”

for additional information on this subject.

“Total Fuel” is  the total amount of  fuel that is

consumed by the engine during operation.

Passwords

“Total Max Fuel” is the maximum amount of fuel that

could have been consumed by the engine  during

operation.

System configuration parameters are protected by

factory passwords. Factory passwords are calculated

on a computer system  that is available only to

Perkins Distributors. Since factory passwords contain

alphabetic characters, only the electronic service

tool may change system configuration parameters.

System configuration parameters affect the power

rating family or emissions.

“Engine Starts” is the total number of times when the

engine has been started.
