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: a main display module, various switches and sensors, an action lamp and an action alarm. The system may include a speedometer/tachometer module. A different number of quad gauge modules may be included in the system.The main display module is the brain of the system. This module receives information from the switches, sensors and other electronic controls 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 can also obtain system diagnostic information.The same monitoring system operates on a variety of different machines. All the possible system functions are not performed on every machine. After the main display module has been installed, the module recognizes the machine. The module will perform only the intended functions for that machine. The main display module is required for the monitoring system to operate. The quad gauge module and the speedometer/tachometer module may not be used on some machines. The maximum number of other modules that can be used with the main display module at any one time is four. The modules that can be used are two quad gauge modules and two speedometer/tachometer modules.Main Display Module
The ten alert indicators (4) show abnormal conditions in the machine.
A six digit display area (9) is provided. The display shows the following modes: machine operational hours (service meter), engine speed (tachometer), machine distance (odometer) and diagnostic codes. The information for the speedometer/tachometer module, and any gauge of the quad gauge module can also be shown as a number on this readout. The display area contains seven unit indicators and a service indicator. The operator selects the information in order to be shown on the display area.
Seven different unit indicators can be shown in the display area. The unit indicators that can be shown are "°C", "kPa", "MILES", "KM", "RPM", "LITERS" and "HOURMETER" symbol. These indicators show the units of measurement for the data on the six digit display area. The indicators are turned ON and OFF in order to correspond with the information on the six digit display area.
In order to indicate a current fault, a service code indicator is used. The service code indicator is used in service mode and diagnostic scrolling mode. Speedometer/Tachometer Module
