BRACKET 3V4174 - Caterpillar

Monitoring Features
The RTD Module monitors eight Platinum RTD inputs. All monitored values are available on the communication data link as read-only information. Temperatures are configured in order to indicate the Suspect Parameter Number (SPN) transmitted by each temperature input. An SPN is an internationally recognized trouble code that is assigned a specific meaning. For example, SPN 171 relates to the Ambient Air Temperature.Each input is fully configurable and can be set to any SPN that is listed in Table 4. The display units are selectable at the EMCP 4 controller as either Fahrenheit or Celsius. The Caterpillar Electronic Technician (Cat ET) is used in order to configure the inputs of the RTD module. Table 4 shows the SPNs that are available for configuration of temperature inputs.
