Customer Specified Parameters

Customer specified parameters allow the engine to

be configured to the exact needs of the application.

Customer parameters may be changed repeatedly as

a customer’s operation changes.

The following information is a brief desc ription of the

customer specified parameters.

Rating Duty Selection

This parameter enables selection of the engine rating

from a series of maps within the ECM. Changing the

rating requires a cus tomer password. The available

ratings within the ECM will vary with the type of

engine and the specification of the engine.

Rated Frequency

This parameter displays the rated frequency of the

genset. This is determined by the rating selection

and the status of the external speed selection s witch.

This parameter is read only.

Rated Speed

This parameter displays the rated speed of the

engine. This is determined by the rating selection

and the status of the external speed selection s witch.

This parameter is read only.

Rated Real Genset Power

This parameter displays the maximum power in kW

of the currently s elected rating. This parameter is

read only.

Rated Apparent Genset Power

This parameter displays the maximum power in kVA

of the currently s elected rating. This parameter is

read only.

Rating Configuration

This parameter displays the configuration of the

currently selected rating. The following list gives the

possible configurations:

• Standby power

• Limited time prime power

• Prime power

• Continuous or baseload power

For definitions of these ratings, refer to ISO8528.

This parameter is read only.

Note: Not all of the above rating configurations will

be available in the software files of every ECM.

E xternal Speed Selection Switch Enable

For dual s peed applications with an external

speed selection switch, this parameter enables the

functionality of the speed selection switch within

the s oftware. Changing this parameter requires a

customer password.

Engine Startup Acceleration Rate

This parameter enables the ac celeration rate of

the engine in RPM per second to be programmed.

The parameter can be programmed from idle speed

to rated speed. Control of this parameter enables

any overshoot in speed on start-up to be limited.

Changing this parameter requires a c ustomer

pas sword.

Droop/Isochronous Switch Enable

This parameter determines whether the external

droop/isochronous switch is enabled or disabled.

Changing this parameter requires a c ustomer

pas sword.

This document has been printed from SPI². Not for Resale

KENR6224

27

Troubleshooting Section

Droop/Isochronous Selection

The engine will normally be run in isochronous mode.

This means that the engine speed will not change,

regardless of the load. If the engine needs to operate

in parallel with another genset or the engine needs

to operate in parallel with the grid, it is nec essary to

operate the engine in droop mode in order to ensure

the stability of the system. This parameter enables

droop/isochronous running selection. Changing this

parameter requires a customer pass word.

Note: If an external droop/isochronous switch is

enabled, the position of this switch will override the

“Droop/Is ochronous” selection.

Engine Speed Droop

If droop operation is selected, this parameter

allows the setting of percentage droop. This is the

percentage of speed reduction with an increase in

load. This parameter has no effect when the engine

is running in isochronous mode. Changing this

parameter requires a customer pass word.

Digital Speed Cont rol Installed

This parameter determines whether input from the

raise/lower switch controls the speed of the engine.

If digital speed control is not installed, the speed of

the engine is controlled by inputs from the analog

throttle or the PWM throttle. This depends on the

input that is selected in the desired speed input

configuration. Changing this parameter requires a

customer password.

Digital S peed Control Minimum Speed

This setting determines the minimum speed range of

both the raise/lower control and the analog control.

For example, if this is set to 100 RPM and the

nominal engine speed is s elected to 1500 RPM, the

minimum speed setting is 1400 RPM. This parameter

does not affect the range of the PWM speed control

as this control has a fixed minimum limit and a fixed

maximum limit. Changing this parameter requires a

customer password.

Digital S peed Control Maximum Speed

This setting determines the maximum speed range of

both the raise/lower control and the analog control. If

this is set to 100 RPM and the nominal engine speed

is selected to 1500 RPM, the maximum speed setting

is 1600 RPM. This setting does not affect the range

of the PWM speed control as this c ontrol has a fixed

minimum limit and a fixed maximum limit. Changing

this parameter requires a customer password.

Digital Speed Control Ramp Rate

This setting determines the rate of change of engine

speed in RPM when the raise/lower switch inputs are

closed. Changing this parameter requires a customer

pas sword.

Crank Terminate Speed

This parameter is used to set the engine speed that

is required before the output from the crank terminate

relay is switched. Changing this parameter requires a

customer password.

Desired Speed Input Arrangement

If a digital speed control is not installed, this

parameter enables selection of either an analog

throttle, a PWM throttle or an ex ternal CAN Bus

speed control. The inputs from the analog throttle,

the PWM throttle or the CAN Bus speed control

are normally used with genset load sharing and

synchronizing controllers. Changing this parameter

requires a customer password.

Note: If a PWM throttle, an analog throttle or a CAN

Bus speed control is selected but there are no inputs

to the terminals for the selected speed control, the

engine will default to running at 1100 RPM.

If a PWM throttle, an analog throttle or a CAN Bus

speed control is not used, the digital s peed control

should be selected.

Fuel Enable Input Configuration

This parameter enables the selection of switch to

battery positive or CAN input for the control of the

injector On and injector Off.

Governor Gain Parameters

The following items are the adjustable parameters for

gov ernor gain:

• Governor Gain Factor

• Governor Minimum Stability Factor

• Governor Maximum Stability

Note: No engineering units are associated with these

numbers.

Note: The programmable range is wide for flexibility.

Values of 1 to 40000 are valid. The full range of this

parameter may not be used on any system. Do not

expect to use the whole range.

slow, the response of the engine speed is slow.

Governor Minimum/Maximum Stability

Factor

The stability factor terms work in order to eliminate a

steady state speed error. There are two gain terms

that are used for stability. If the error is greater than

20 RPM and if the error is increasing, the maximum

stability gain is functioning. If the error is less than

20 RPM, the minimum stability gain is used. This

function allows the use of a high gain that would

Determine the desired scenario in order to tune

the engine. For example, check if the engine has

poor response during specific load assignments

or specific load dumps.

Perform the desired load change that is detailed

in step 4. Check the response of the engine by

viewing the following parameters.

• The engine speed on the control panel on the

genset

• The frequency response of the system bus to

the load change

• Listening to the response of the engine

stability gain is set too high, the governor will

provide more fuel than the amount that is

nec essary to bring the error to zero. The additional

fuel will cause the engine speed to overshoot and

the engine to produce excessive combustion noise.

stability gain is set too low, excessive time is taken

in order to stabilize the engine s peed.

Tuning Procedure

1. Turn the keyswitch to the OFF/RESET position.

Before the tuning procedure is started, connect

the electronic serv ice tool and then check

that engine overspeed protection is enabled.

Engine overspeed is configured on the

“Service\Monitoring System” sc reen on the

electronic service tool.

NOTICE

Performing engine governor tuning without engine

overspeed protection could result in serious engine

damage.  Ens ure  that this  parameter is  ON while

performing this proc edure.

Note: Usually, the gain factor of the governor should

be lower than the minimum stability fac tor of the

gov ernor in order to obtain optimum performance.

The maximum stability factor is typically a smaller

value than the minimum stability gain and the

gov ernor gain factor.

7. Repeat steps 5, 6 and 7 until a desired engine

response can be met. Use large adjustments

(10% of original gain) initially to generally tune the

engine in the proper manner. As the response

gets closer to the desired value, increase the

gains in smaller increments (1% of total gain).

Engine monitoring

Perkins provides an engine monitoring system that

is ins talled at the factory. The system monitors the

following parameters:

• Engine oil pressure

• Coolant temperature

Intake manifold air temperature

Fuel temperature

Diagnostic codes that are stored in memory are

called Logged diagnostic codes. The fault may have

been temporary or the fault may hav e been repaired

since the fault was logged. For this reason, logged

codes do not necessarily mean that something needs

to be repaired. Logged diagnostic codes are meant

to be an indication of probable causes for intermittent

faults.

The monitoring system has three levels of operation.

The levels are described below.

Warning Operation

In the Warning condition, the ECM causes the

warning lamp to come ON. The warning lamp

indicates that a fault has been detected by the engine

monitoring system. No further action by the ECM or

the engine occurs.

Action Alert Operation

In the Action Alert condition, the ECM causes the

action alert lamp to come on. The Action Alert lamp

indicates that a fault has been detected by the engine

monitoring system. This condition is normally wired

in order to cause a shutdown and the shutdown is

controlled by the control panel on the mac hine.

Shutdown Operation

If the fault reaches the Shutdown c ondition, the ECM

causes the shutdown lamp to come on. Unless the

engine is in a Critical Override condition, the engine

will shut down.

Monitoring the Fuel Temperature

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.

The sensor is also used to warn the operator of

exces sive fuel temperature with a diagnostic event

code. Excessive fuel temperatures can adversely

affect engine performance.

Self-Diagnostics

The electronic system has the ability to diagnose

faults. When a fault is detected, a diagnostic code

is generated and the diagnostic code is stored

in permanent memory (logged) in the ECM. The

diagnostic lamp is also activated.

When diagnostic codes occur, the diagnostic codes

are referred to as Active diagnostic codes. Active

diagnostic c odes indicate that a fault of some kind

currently exists.

Diagnostic codes that identify operating conditions

outside the normal operating range are called Events.

Event codes are not typically an indication of a fault

with the electronic system.

Note: Some of the diagnostic codes require

pas swords to clear the code.

Effect of Diagnostic Codes on

Engine Performance

The diagnostic lamp comes on when a specific

condition exists. When the ECM detects an engine

fault, the ECM generates an active diagnostic code

and the diagnostic code is logged. The diagnostic

code is logged in order to record the following

information:

• The date

• The time

• The number of occurrences of the fault

The two types of diagnostic codes are Fault codes

and Event codes.

Fault Codes

Fault codes are provided in order to indicate that

an electrical fault or an electronic fault has been

detected by the ECM. In some cases, the engine

performance can be affected by the condition that is

causing the code. More frequently, there is no effect

on engine performance.

Event Codes

Event codes are used to indicate that some

operational fault has been detected in the engine by

the ECM. This does not usually indicate an electronic

malfunction.

The ECM also provides a cloc k in order to add the

date and the time to the following critical event codes:

• 360-3 Low oil pressure shutdown

• 361-3 High coolant temperature shutdown

information.

5. Check the fuel filters.

6. Cold weather adversely affects the characteristics

of the fuel. Refer to the Operation and

Maintenance Manual for information on improving

the characteristics of the fuel during cold weather

operation.

7. Check the fuel pressure during engine cranking.

Check the fuel pressure after the fuel filter. Refer

to Systems Operation/Testing and Adjusting, “Fuel

System” for the correct pressure values. If the fuel

pressure is low, replace the fuel filters. If the fuel

pressure is still low, check the following items: fuel

transfer pump, fuel transfer pump coupling, and

fuel pressure regulating valv e.

Diagnostic Codes and Event Codes

Certain diagnostic codes and/or event codes may

prevent the engine from starting. Connect the

electronic service tool and check for active codes

and/or for logged codes. Troubleshoot any codes that

are present before continuing with this procedure.

Troubleshooting Section

Position Sensors

1. Crank the engine and observe the engine speed

on the status screen of the electronic service

tool. If the electronic service tool indicates zero

rpm, refer to the Troubleshooting Guide, “Engine

Position Sensor Circuit - Test”.

Note: Upon initial cranking, the status for engine

speed may indicate that the engine speed signal is

abnormal. This message will be replaced with an

engine s peed once the ECM is able to calculate a

speed from the signal.

2. If an engine s peed is present, check the sensor

ins tallation. If the sensor is not properly installed,

the ECM may read engine speed, but the ECM

cannot determine the tooth pattern. The ability for

the ECM to read the tooth pattern is necessary

to determine the cylinder position. Engine speed

is present when engine speed is greater than 50

rpm. Refer to the Troubleshooting Guide, “Engine

Position Sensor Circuit - Test”.

Electronic Unit Injector

1. Ensure that the valve cover connectors for the

injector harnesses are fully connected and free of

corrosion.

2. Perform the “Injector Solenoid Test” on the

electronic service tool in order to determine if all

of the injector solenoids are being energized by

the ECM. Refer to the Troubleshooting Guide,

“Injector Solenoid Circuit - Test” for additional

information.

Combustion

Check the engine for faults in the combustion system.

i02557751

Engine Has Early Wear

Probable Causes

• Incorrect engine oil

• Contaminated engine oil

• Contaminated air

• Contaminated fuel

• Low oil pressure

Recommended Actions

Incorrect Engine Oil

Use engine oil that is recommended and change the

engine oil at the interval that is recommended by the

Operation and Maintenance Manual.

Contaminat ed Engine Oil

Drain the crankcase and refill the crankcase with

clean engine oil. Ins tall new engine oil filters. Refer to

the Operation and Maintenance Manual.

If the oil filter bypass valve is open, the oil will not

be filtered. Check the oil filter bypass valv e for a

weak spring or for a broken spring. If the spring is

broken, replace the spring. Refer to the Disassembly

and Assembly manual. Make sure that the oil bypass

valve is operating correctly.

Contaminated Air

Inspect the air inlet system for leaks. Inspect all of

the gaskets and the connections. Repair any leaks.

Inspect the air filter. Replace the air filter, if necessary.

Contaminated Fuel

Inspect the fuel filter. Replace the fuel filter, if

nec essary.

Contaminants in the fuel such as hy drogen sulfide

and sulfur can lead to the formation of acids in the

crankcase. Obtain a fuel analysis.

Low Oil Pressure

When some components of the engine show bearing

wear in a short time, the cause can be a restriction in

a passage for engine oil.

An indicator for the engine oil pressure may indicate

sufficient pressure, but a component is worn due to a

lack of lubrication. In s uch a case, look at the passage

for the engine oil supply to the component. Refer

to the Systems Operation, Testing and Adjusting

manual.
