Caterpillar Monitoring System Introduction
The scope of this document is the basic Caterpillar Monitoring System. This includes the switches, sensors, external monitoring hardware (horn, lamp), the Serial Peripheral Interface (SPI) peripherals such as the Quad Gage, the Lamp Display modules as well as some basic Caterpillar Monitoring System operational functions.The Caterpillar Monitoring System is an electronic monitoring system that continuously watches machine systems. The system is a flexible modular monitoring system that includes the following devices:
Main display module
Action lamp
Action alarm
Speedometer/Tachometer module
Gauge module
Switches and sensorsThe main display module is the brain of the Caterpillar Monitoring System. The Caterpillar Monitoring System receives information from switches, sensors, and other electronic control modules on the machine via the Cat Data Link. The main display module processes all of the information. The module then activates various outputs. The outputs could be in the display area of the main display module, the quad gauge module, the speedometer/tachometer module, the action lamp, or the action alarm. The display components show the condition of the machine systems. The operator or the service person can also obtain system diagnostic information.When power is applied, the machine serial number is used in order to determine the type of machine that is being operated. The module will perform only the intended functions for the machine. The main display module is required for the monitoring system to operate.
