C4.4 and C6.6 Engines for Caterpillar Built Machines Customer Specified Parameters Caterpillar

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 description of the customer specified parameters. The following parameter values are included with the descriptions:

• Minimum

• Maximum

• Default

Engine Rating Parameter

Rating Number

The rating number is the selected rating within a power rating family. The flash file defines the power rating family. The flash file can contain one to four ratings. The rating number defines the power rating that is used within the power rating family.

Low/High Idle Parameters

Low Idle Speed

The "Low Idle Speed" is the minimum engine rpm.

High Idle Speed

The "High Idle Speed" is the maximum engine rpm.

ECM Identification Parameter

Equipment ID

"Equipment ID" is the identification of the equipment that is assigned by the customer. The "Equipment ID" is only for reference only by the customer. The "Equipment ID" is not required by the Electronic Control Module (ECM).

Miscellaneous

Monitoring Mode Shutdowns

"Monitoring Mode Shutdowns" controls the shutdown feature that is associated with the engine monitoring feature. When this feature is enabled and an event code with a "-3" suffix is detected, the engine will be shut down.

Monitoring Mode Derates

"Monitoring Mode Derates" controls the derate that is associated with the engine monitoring feature. When this feature is enabled and an event code with a "-2" is detected, the engine will be derated.

Limp Home Desired Engine Speed

The "Limp Home Desired Engine Speed" is the maximum speed of the engine when the engine has been derated.

J1939 Continuous Fault Handling

Remote Torque Speed Control Enable Status

The "Remote Torque Speed Control Enable Status" parameter determines the way that faults will be handled by the ECM when the "J1939 Torque Speed Control (TSC1)" message is used as a speed request input to the ECM. Programming the "Remote Torque Speed Control Enable Status" to "Enabled" will cause the ECM to display a fault code if a valid TSC1 message is not received by the engine ECM within 30 seconds of the engine starting. If the" Remote Torque Speed Control Enable Status" is programmed to "Disabled", the engine will display a 247-12 Data Link Malfunction immediately after a loss of a TSC1 message. Program "Remote Torque Speed Control Enable Status" to "Enabled" if the ECM will always be receiving a TSC1 message.

Configurable Inputs

Coolant Level Sensor

A coolant level sensor is an optional switch input. Programming the "Coolant Level Sensor" parameter to "Enabled" notifies the ECM that a coolant level sensor input is present on pin J1:38. If this parameter is programmed to "Enabled" and the coolant level falls below the measured level, a "E2143-3" event code will be displayed.

Air Filter Restriction Switch Installation Status

An "Air Filter Restriction Switch" is an optional switch input. Programming the "Air Filter Restriction Switch Installation Status" parameter to "Enabled" notifies the ECM that an input from the air filter restriction switch is present on pin J1:47. When this parameter is programmed to "Enabled" and the air filter restriction switch closes, an E172-1 or J107-15 event code will be displayed.

Fuel/Water Separator Switch Installation Status

A fuel/water separator switch is an optional switch input. Programming the "Fuel/Water Separator Switch Installation Status" parameter to "Enabled" notifies the ECM that a fuel/water separator switch input is present on pin J1:44. When this parameter is programmed to "Enabled" and the fuel/water separator switch closes, an E232-1 or J97-15 event code will be displayed.

User Defined Switch Installation Status

A user defined shutdown switch is an optional switch input. Programming the "User Defined Switch Installation Status" parameter to "Enabled" notifies the ECM that a user defined switch input is present on pin J1:48. If this parameter is programmed to "Enabled" and the user defined shutdown switch closes, the engine will shut down.
