The Caterpillar Monitoring System includes the following components.
(1) Quad gauge module
(2) Main display module (EMS) for the tractor
(3) Speedometer, tachometer, and actual gear indicator
(4) Indicators
(5) Action lamp (tractor)
(6) Mode select switch (tractor)
(7) Tractor-Scraper select switch
Also, the monitoring system includes an action alarm that is not shown.
The monitoring system is designed to alert the operator of a problem in one or more of the machine systems that are covered. The main display module includes individual alert indicators for each machine system. The action lamp and individual alert indicators will light when a problem occurs. Also, the action alarm will sound when certain problems occur.
Main Display Module
 | |
| Illustration 2 | g00927697 |
The main display module includes two rows of five alert indicator lights and a digital display window. The indicator lights monitor machine systems of the tractor and scraper. Digital display window (18) will display important numeric readouts for different machine systems. The default information that is displayed is for the tractor.
Alert Indicators
| Engine Coolant Flow (8) - This alert indicator shows that there is no coolant flow to the selected engine or that there is a failure in the cooling system. The failure could be in any component of the cooling system. |
| Air Pressure (9) - This alert indicator shows that there is low air pressure in the air system or that there is a failure in the air system. |
| Engine Oil Pressure (10) - This alert indicator shows that there is low engine oil pressure for the selected engine. |
| Secondary Steering (11) - This alert indicator shows that the secondary steering system is engaged. When the secondary steering system is engaged, the primary steering system has failed. |
| Engine Coolant Temperature (12) - This alert indicator shows that the selected engine coolant temperature is too high. |
| Torque Converter Oil Temperature (13) - This alert indicator shows that the oil temperature for the selected torque converter is too high. |
| Parking Brake (14) - This alert indicator shows that the parking brake has been engaged. The alert indicator should go out when the parking brake is disengaged. |
| Charging System (15) - This alert indicator shows that the alternator for the selected engine is malfunctioning. |
| Power Train System (16) - This alert indicator shows that the engine control system or the transmission control system has a problem. |
| Hydraulic System Failure (17) - This alert indicator shows that the hydraulic system is malfunctioning or that the hydraulic system has failed. |
Digital Display Window
Digital display window (18) is used to show different sets of data for several machine systems. The default readout of the display shows the tachometer for the scraper engine. The mode select switch is used in order to select the functions on digital display window (18) .
Warning Categories
The Caterpillar Monitoring System provides three warning categories. The first warning category requires only operator awareness. The second warning category requires an operator response. The third warning category requires immediate shutdown of machine systems.
Warning Category 1
In this category, only the alert indicator comes on. This category alerts the operator that the machine system needs attention. Failure of these systems will not endanger the operator. Failure of these systems will not cause serious damage to the machine components. The following indicators can be illuminated with Warning Category 1:
- Parking Brake (14)
- Charging System (15)
- Power Train System (16)
- Hydraulic System Failure (17)
Warning Category 2
In this category, the alert indicator and the action light come on. This category requires a change in machine operation in order to reduce excessive temperature in one or more of the machine systems. The following indicators can be illuminated with Warning Category 2:
- Engine Coolant Temperature (8)
- Torque Converter Oil Temperature (13)
- Power Train System (16)
- Hydraulic System Failure (17)
Warning Category 3
In this category, the alert indicator and the action light come on and the action alarm sounds. This category requires immediate shutdown of the machine in order to prevent injury to the operator and/or severe damage to the machine. The following indicators can be illuminated with Warning Category 3:
- Engine Coolant Temperature (8)
- Air Pressure (9)
- Engine Oil Pressure (10)
- Secondary Steering (11)
- Parking Brake (14)
- Charging System (15)
- Power Train System (16)
- Hydraulic System Failure (17)
