EMCP3 Caterpillar

The spare analog input is to be connected to a resistive sender such as the coolant temperature sensor or the oil pressure sensor. Each analog input can read a zero to 2k ohm resistive sender.

Note: The EMCP 3.1 does not have a spare analog input. The EMCP 3.2 and the EMCP 3.3 each have a single spare analog input.

Note: The R/T map in the EMCP 3 for the spare analog input differs between EUI engines and MUI engines. In EUI engines, the spare analog is reserved for user-defined purposes input. In MUI engines, the spare analog input is used for the input for oil temperature.

The spare analog input can be configured for six specific temperatures. In addition to temperatures, this input can be factory set to monitor pressures and to monitor levels. Consult the factory for information about applications that use the Spare Analog Input.

Menu Navigation

Use the EMCP 3 to navigate to the spare analog input menu. The spare analog input menu is used to program the input.

1. At the "MAIN MENU" use the arrow keys and enter key to select "CONFIGURE".

2. Use the arrow keys and enter key to select "SETPOINTS".

3. Use the arrow keys and enter key to select "I/O".

4. Use the arrow keys and enter key to select "SPARE ANALOG INPUT".

Parameters that can be Configured

Parameters that can be configured for the spare analog input include the following:

• Enable/Disable

• Suspect parameter number

• Thresholds and time delays

Enable/Disable

If the spare analog input is used, then the enable/disable set point must first be enabled.

If the spare analog input is not used, then the enable/disable set point must be disabled.

If the spare analog input is enabled, but is not being used, then diagnostic codes will be logged.

Suspect Parameter Number (SPN)

Suspect parameter numbers can be configured for the following list of possible inputs.

• Air filter differential pressure

• Ambient air temperature

• Engine coolant level

• Engine oil temperature

• Exhaust temperature

• Right exhaust temperature

• Left exhaust temperature

• Fire extinguisher pressure

• Fuel filter differential pressure

• Fuel level

• External tank fuel level

• Generator rear bearing temperature

• Oil filter differential pressure

• Starting air pressure

Additional Parameters

The following threshold and time delay parameters are numerical value entries.

• High warning threshold

• High warning time delay

• High shutdown threshold
