Event Categories
The RAC system has the flexibility that allows the user to change the trigger values of the RAC Event Category Groups. The user is allowed to change the trigger values in order to accommodate for the various underfoot conditions. Adjusting the trigger values also allows the user to manage the number of events that are created. There are three Category Groups of RAC Events."Group - One"
"Group - One" is the most sensitive setting and will generate the most events as compared to "Group -Two" or "Group - Three" under the same haul cycle conditions. Customers with good haul road maintenance will be able to use the default setting of "Group - One" immediately. Other sites with less haul road maintenance will need to start with "Group-Two" or "Group-Three" settings. Then, as haul road conditions improve you may reduce the trigger levels. The primary purpose of this process is to manage (reduce) the number of RAC events. "Group - One" settings coincide with factory design guidelines for component life that are discussed in this manual. "Group - One" is also the default setting for new RAC installations.Note: Caterpillar recommends "Group - One"settings for all applications. "Group - Two"
The "Group -Two" trigger values are 1.35 times the settings for "Group - One". "Group - Three"
"Group-Three" trigger values are 1.7 times the settings of "Group-One".Setup of the Event Category
In order to change the "RAC Group Settings", connect VIMSpc to the machine. This allows programming of the "RAC Group Settings" via the VIMS keypad. After communications have been established, press the "tab" key on the service tool until the "Status" screen is shown. Enter the letters "RAC" via the VIMS keypad. Then press the "OK" key. Verify the machine data (such as the serial number and SMH). The event Category that is presently programmed will appear on the VIMS message center. Enter the desired "Group" setting via the VIMS keypad in order to change the Category.
Enter "1" for "Group - One", then press the "OK" key
Enter "2" for "Group - Two", then press the "OK" key
Enter "3" for "Group - Three", then press the "OK" key.After this procedure is complete, turn the key start switch to the OFF position and then turn the key start switch back to the ON position. The new Group is now active. The RAC System provides the ability to increase the trigger settings above the recommended factory default of "Group - One". But, "Group - Two" and "Group -Three" should only be used on an interim basis. The intent if to work toward the "Group-One" settings. As haul road conditions improve through the use of the RAC System, the trigger categories that are used should be progressively reduced until "Group - One" is achieved. Note: Due to the environmental conditions (heavy rain fall, poor building material for roads, etc.) present at some locations, some sites may not be able to achieve the "Group-One" setting.
