VIMSTM system block diagramThis manual is for VIMSTM 3G and the systems that utilize the data that is collected by the VIMS A5N2 ECM. VIMS 3G is a standard feature that collects data for other machine systems. This manual describes the hardware, the software, and the interfaces that are used with VIMS 3G. 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 will store information about events as data. The operator is alerted to the existence of abnormal machine conditions via the Messenger display module. A high engine coolant temperature is an example of an event. Events are related to a machine system. The operator needs to respond to an event in most cases. 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 Messenger 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. The configuration software also identifies the available functions of VIMS 3G. 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. Types of Recorded Data
The occurrence of certain events, diagnostics, and machine conditions are recorded in the VIMS 3G onboard memory. The information is organized into seven categories. This information is used to analyze problems with the machine. The seven categories of information are:Event List - The event list is a record of stored events and diagnostics that have occurred on the machine. Not all events are stored. The record contains the last 500 events and diagnostics that are listed in the order of occurrence. The newest events appear at the top of the list. The event list transfers the oldest data into the event summary list when the event list exceeds 500 records. The event summary list is composed of the first five occurrences, the last five occurrences, and the worst five occurrences recorded events. The event summary list is limited to storing 500 records.The event list is accessible from the Messenger display or with VIMSpc. Snapshot - The Snapshot stores a segment of history for all parameters (channels) at a 1 second interval. The snapshot relates to a set of predefined events. A snapshot is triggered automatically for a severe event. The snapshot is then stored in memory. The configuration software designates the events that are considered to be severe events. The "Trigger Snapshot" menu option in can be used in order to initiate a snapshot
