NUT 1D4717 - 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.
At the "MAIN MENU" use the arrow keys and enter key to select "CONFIGURE".
Use the arrow keys and enter key to select "SETPOINTS".
Use the arrow keys and enter key to select "I/O".
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 delaysEnable/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
