The Vital Information Display System (VIDS) is an electronic monitoring system that continuously checks machine systems. The VIDS is composed of software components and hardware components. The hardware components of VIDS consist of the following items:
- VIDS ECM
- Message center module
- Keypad
- Quad gauge module
- Speedometer/Tachometer module
- Various switches
- Sensors
- Lamps
- Alarms
The software components are the input system, monitor subsystem manager, and the operator interface.
Data Links
The VIDS components communicate with each other, with other electronic controls on the machine, and with systems off the machine. The VIDS components communicate through data links. The VIDS uses the two data links that are listed here:
CAT Data Link - This two-wire data link allows communication between the VIDS ECM and all machine control systems.
SPI data link - This four-wire data link allows communication between the VIDS ECM and all display components.
The VIDS uses four types of data (information). The types of data are listed below:
- Sensed Data is read from the sensors. The sensors communicate continuously with the VIDS ECM or with other electronic control modules.
- Internal Data is generated within the VIDS ECM. An example of internal data is the date and time.
- Communicated Data is sent from other machine systems to the VIDS ECM through the data link. An example of communicated data is the engine speed. The engine speed is received from the electronic engine control.
- Calculated Data is determined mathematically by the VIDS ECM. An example of calculated data is the event duration in the event list.
Data Events and System Events
The VIDS alerts the operator of abnormal machine conditions that exist. All abnormal machine conditions are called data events (machine events). An example of a data event is high engine coolant temperature. The VIDS ECM also alerts the operator of problems that occur in other electronic modules that are used on the machine. In addition, the VIDS ECM alerts the operator of problems that occur within the ECM. These system failures are called system events. A typical example of a system event is listed here: The signal voltage of the power train oil temperature sensor is above the normal limit. The VIDS ECM stores information about each event (data and system). This stored data can be used by service personnel while maintenance is performed on the machine. This data can also be used by service personnel to troubleshoot machine systems.
DATA events are events that relate to a machine system. In most cases, the operator needs to RESPOND to this event. An example of a data event is given below: The hydraulic oil temperature is too high. Pressing the "MORE" key will show additional information about the event on the message center when a data event is present. During temperature warnings, the key will cause the display to show the actual temperature.
SYSTEM events are events that relate to an electrical system problem. System events usually require a service technician to MAKE A REPAIR. Pressing the "MORE" key will display the diagnostic codes (MID, CID, and FMI).
Note: The VIDS ECM can determine if the sensor is actually faulty or if the machine system that is being monitored is abnormal. The VIDS ECM can determine the problem if data events and system events for the same machine system are detected simultaneously.
The types of indicators that are available on the display components are listed below:
- Alert indicator (4) on the message center module shows that an event is detected.
- Universal gauge (10) on message center module (3) shows the value of the parameter that is presently displayed on message area (9) .
- Message area (9) on the message center module displays the following items: parameter name, status of the parameter, event information, status of the machine, service hour meter and any operator related instructions.
Diagnostic information is stored for most level one events, most level two events and all level three events even if the event is not present at the time of troubleshooting.
Event List
The event list is a record of the stored events that have occurred on the machine. Some events such as "Low Fuel Level" are not stored.
The event list is accessible from the message center in the cab.
Event Summary in Caterpillar Electronic Technician (ET) - The VIDS ECM stores the events in a summary log that is used with the ET service tool.
Note: In order to avoid duplication of events in the ET, only events that are stored in the summary log with the VIDS module identifier can be viewed with the ET. Events that are stored under other ECM module identifiers within the summary log may be viewed through the ET by selecting the "Include All ECM's" check box within the ET logged diagnostic code screen.
Note: Events that are stored in the summary log should be cleared through the VIDS menus via the keypad on the D10R (S/N: AKT), on the D11R (S/N: 7PZ), and on the D11RCD (S/N: AAF) machines. See the System Operations, "Menus" section of this manual for additional information.
