Monitoring System

The monitoring system continuously monitors all machine systems and communicates with the ECMs of other systems via the CAN data link.

The hardware components of the monitoring system are:

Indicators and Gauges (Dash panel)
Graphical display module (Advisor)
VIMS^TM

The monitoring system can indicate warnings that have occurred in the ECMs of other systems, including:

Brake
Chassis
VIMS^TM
Engine

VIMS^TM 3G Monitoring System

VIMS^TM 3G is a standard feature that monitors payload operations and collects data for other machine systems.

VIMS 3G data is used to assist the service personnel with machine maintenance and troubleshooting. All abnormal conditions on the machine system are called events. VIMS 3G stores information about events as data. The operator is alerted to the existence of abnormal machine conditions via the Advisor display module. A high engine coolant temperature is an example of an event.

Events are related to a machine system and usually require an operator response. For example, the operator needs to modify operation to cool the oil temperature for the converter when the temperature is too high. When such an event is present, the operator is shown information on the Advisor screen. A fault with the electrical system of the machine is called a diagnostic. A diagnostic requires a service technician to make a repair.

Feature Variations

VIMS 3G is designed to operate on several different types of machines. All of the possible functions of VIMS 3G are not needed on every type of machine.

Configuration software is used to identify the type of machine and the available VIMS 3G functions.

Diagnostic Information

Diagnostic information is stored in VIMS 3G for all system events and diagnostics. The information is stored even if the condition is not present at the time of troubleshooting.
