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

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.

Governor Gain Factor
The governor gain factor is multiplied to the difference
between desired speed and actual speed.
large, the engine speed can overshoot the desired
speed. The overshoot is caused by an excessive
correction or an instability of a steady state.
that is nec essary to accelerate the engine to the
des ired speed must be obtained by increas ing the
stability terms to a higher value. As this process is
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

Start the engine. On the engine mounted genset
control panel, check that the engine has reached
rated speed. This panel will serve as the reference
point for the speed during this procedure.
Enter the “Configuration Parameters” screen on
the electronic service tool.
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
Use the listed suggestions in order to determine
the gains that require adjustment.

engine is operating near the desired speed.
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
Engine speed
Boost pressure
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

and/or replace the lines.
3. Check the fuel tank for foreign objects which may
block the fuel supply.
4. Prime the fuel system if any of the following
procedures have been performed:
• Replacement of the fuel filters
• Servic e on the low pressure fuel supply circuit
Note: A sight glass in the low pres sure supply line
is helpful in diagnosing air in the fuel. Refer to
Systems Operation, Testing and Adjusting for more
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.
Electrical Power Supply to the ECM

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.
