Monitoring Features
Thermocouples are given a type designation that is based on the range of temperatures that the thermocouple can accurately measure. The thermocouple module monitors 20 "Type-J" or "Type-K" thermocouple inputs.Each input can be configured and can be set to any SAE CAN Suspect Parameter Number (SPN) that is listed in Table 4. An SPN is an internationally recognized code that is designated with a specific meaning. For example, SPN174 is designated as "Fuel Temperature".The display units are selectable at the EMCP 4 controller as either degrees fahrenheit or as celsius. All monitored values are available on the data link as read-only information. Temperatures are configured to indicate the SPN that is transmitted by each temperature input.
