The Caterpillar Electronic Monitoring System for Locomotive applications contains the items that are listed below.
- Main display module
- Three gauge modules
- Various switches
- Various sensors
- Action Alarm
The Main Display Module is the brain of the system. This module receives information from the switches, sensors and other electronic controls that are on the engine through the CAT Data Link. The Main Display Module processes this information and the Main Display Module outputs the information to the gauge clusters. The Main Display Module also outputs the information to the Alarm. The engine systems status and the system diagnostic information are shown to the operator through the components of the display. The type of information that is shown is dependent on display mode.
The display area on the main module indicates the following items.
- °F
- °C
- kPa
- psi
- RPM
- LITER
- "GAL/H"
- -10
- VOLTS
- Hour Meter symbol
- "SERV CODE"
- Six digit display area
The six digit display area displays Diagnostic Codes for the engine ECM and the Caterpillar Monitoring System. The display also provides the engine operational hours and engine speed (RPM). Numerical values for the individual gauges are also displayed on the six digit display area. An active system diagnostic fault is indicated when the "SERV CODE" is ON.
