Alert indicator (7) notifies the operator of an abnormal condition in a machine system. The main module uses information from the interface modules and any other electronic control modules on the machine to determine when an abnormal condition is present. The main module then FLASHES alert indicator (7). When alert indicator (7) FLASHES, an abnormal condition exists. For more information, refer to the Systems Operation, "Warning Operation" section in this manual.

Data logging indicator (8) is a series of dots that scroll when data logging is turned on. The dots only scroll when data logging is turned on from the keypad.

Message area (9) identifies the machine system parameter with an abnormal condition. The first line shows the parameter and the parameter status. The second line prompts the operator for a reaction. When alert indicator (7) is FLASHED, the machine system parameter with the abnormal condition is shown in the message area. For more information, refer to the Systems Operation, "Warning Operation" section in this manual. Message area (9) is also used to show the event lists, active diagnostic events (MID, CID, and FMI format) and other requested information.

The system default information is shown on the message area during normal operation. The default information is referred to as the background mode. Information that is shown in the background mode is listed here:

• Time of day

• Odometer (9.3X class of software or later)

• Total machine hours. The total machine hours are based on engine running time.

• On trucks, the payload weight is the information that is shown in the background mode when the truck is being loaded.

• On loaders, the payload weight is also the information that is shown in the background mode when the payload system is ON.

Universal gauge (10) shows a relative value of the parameter in message area (9). For sensor type parameters, universal gauge (10) shows the relative value of the event parameter. Switch type parameters are not shown on universal gauge (10). Universal gauge (10) can also show the RELATIVE value of any valid machine system parameter. The ACTUAL value can be viewed by entering the desired parameter number on the keypad and pressing the "GAUGE" key or pressing the "F1" key while the event is present.

Gauge warning area (1) is a bar that can be located at either end of universal gauge (10). The bar that is used is determined by the parameter that is being displayed. Gauge warning areas (11) may be illuminated in order to indicate an abnormal condition. In illustration 1, gauge warning area (11) is illuminated in order to show the abnormal condition: "TRN TEMP HI". The lower end of the gauge would have illuminated if there was an abnormal condition: "ENG OIL PRES LO"

The 133-1840 VIMS Message Center Module or later can be adjusted for the best viewing angle and the best backlighting intensity. However, the machine must be equipped with the V3.0 hardware and the 9.X class or later of onboard software to use these advanced features. Message centers prior to the 133-1840 VIMS Message Center Modules allow backlight adjustment. However, 9.X software is required. The viewing angle (contrast) cannot be adjusted. Refer to Table 1 for additional information on features of the message center module.
