(11) Gauge warning area During normal operation, the VIMS display components provide the operator and the service technician with the information that is listed here:
The display components indicate whether the Vital Information Management System is operating properly. Whenever the key start switch is turned to the ON position, some of the VIMS outputs (gauges and message center module) briefly operate. This is a system self-test of the display components. See the Systems Operation, "System Self Test" topic for the complete test of the VIMS outputs.
The measured value of present system conditions are shown on the display components. The machine systems are continuously monitored. The normal range value of the gauges in the quad gauge module are shown in the central region.
The display components will indicate whether an abnormal machine system condition (data event) exists. The machine systems are continuously monitored. When an abnormal condition (problem) exists, alert indicator (7) FLASHES. Message area (9) shows the system parameter with the abnormal condition and the value of the parameter. Universal gauge (10) also shows the relative value of the abnormal parameter. The service indicator lamp is turned ON and the event may be stored in the memory of the VIMS ECM. A problem that is more severe requires the action lamp to FLASH and the action alarm is required to SOUND. See the Systems Operation, "Warning Operation" section.
The display components will indicate when a VIMS failure/ system event exists. Continuous checks are made for the existence of electrical failures in the VIMS electronic control module and in the other electronic control modules installed on the machine. When the VIMS detects a diagnostic type of system event, the service indicator lamp is activated. The event is shown on the message area. The event is also stored in the memory of the VIMS electronic control module. See the Systems Operation, "Service Operations" section. The VIMS enters the normal mode when the key start switch is turned to the ON position. This is the mode of "normal" operation. The system will enter the normal mode after the installation of valid source software and configuration software. Refer to the Systems Operation, "VIMS Electronic Control Module" section of this manual for additional information on the modes of operation.
