HOSE-WATER INLET 2610715 - Caterpillar

The I/O module, located in the autonomous cabinet, communicates with the MCM over CAN 2. The I/O module acts to expand the input and output capacity of the MCM. The expanded capacity includes the many components. Refer to System Operations, "Electrical Input Components" for more information on components.Pulse Per Second Buffer (PPS Buffer)

The PPS buffer is used as a converter to change the TTL logic signal from the PCS output to an RS232 signal. After conversion, the module provides multiple RS232 outputs for other modules for timing synchronizationTire Monitoring Module
Illustration 14 g03226818
The tire monitoring system TMS for the autonomous mine truck AMT is designed to detect tire pressure, temperature, calculate temperature compensated tire pressure, calculate tire deflation, generate messages for diagnostics, and to detect a tire blowout so the AMT can take appropriate action.The system uses a tire-monitoring module TMM to communicate with multiple wheel sensors through wireless radio. Each wheel sensor measures temperature and pressure for radio transmission. TMM communication with the autonomous system is through the truck Chassis ECM and the MCM master.During operation, tire sensors and measure gauge pressures and temperatures every 4 seconds. Each sensor, using a unique identification number programmed in at the time of installation, transmits data to the TMM for processing. The TMM calculates compensated tire pressures using both stored cold inflation pressure data for each tire and the transmitted gauge pressures and temperatures. Results are communicated to the Chassis ECM, through the autonomous system and to the Cat MineStar System office so that gauge pressure and temperature compensated pressure are displayed for all wheel sensors that are installed.The TMM internal calculations are also used to determine thresholds and events. The Chassis ECM reads the messages from the TMM to determine the current diagnostic trouble codes DTC, tire deflation, or tire blowout requiring immediate AMT action.ReferenceFor more information on the Tire Monitoring System, refer to Systems Operation, Troubleshooting, Testing and Adjusting, UENR2211, "793F CMD Off-Highway Truck (Command for Hauling) Chassis Electronic Control System".
