C4.4 Generator Set Engines 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 personality module defines the power rating family. The personality module can contain one to four ratings. The rating number defines the power rating that is used within the power rating family.

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.

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

Overspeed Protection

The "Overspeed Protection" speed is the engine rpm when a shutdown will occur. Overspeed protection is used in order to protect the engine from damage. Overspeed protection must be enabled in "Monitoring Mode Shudowns".

1500 rpm	2100 rpm	2100 rpm

Configurable Governor Droop

"Configurable Governor Droop" allows the engine to run in "droop mode" when the genset is operated in parallel with other gensets.

Coolant Level Sensor

Note: This parameter is only applicable if a coolant level switch is installed.

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.

Disabled Enabled	Disabled

Air Filter Restriction Switch Installation Status

Note: This parameter is only applicable if an air filter restriction switch is installed.

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.

Value	Default
Disabled Enabled	Disabled

Fuel/Water Separator Switch Installation Status

Note: This parameter is only applicable if a fuel/water separator switch is installed.

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.
