DXF files or SVL files can be used for avoidance zones guidance. DXF files must be given a name using the following convention: *.avoid.dxf. SVL files that are generated by the AccuGrade Office Software must use the following convention: *.avoid.svl. The avoidance zone files must contain one or more polygons in order to define the area to avoid.
Note: SiteVision Office Software can also be used instead of AccuGrade Office Software.
The *.avoid.dxf or *.avoid.svl files must reside in the root folder of the data card. The files load and display in the plan view when the Display is turned on. Warnings are given to the site avoidance zones until the Display is turned off.
When the DXF file or an SVL file is created for an avoidance zone, the file does not need to have the polygon boundary color or the fill color set defined. This is automatically done by the AccuGrade System. When the boundary color is defined in the DXF file, the AccuGrade System displays this color.
A measurement for the "Ripper back from the cutting edge" can be set in the "Machine Dimensions" dialog. The "Ripper back from cutting edge" measurement is used in avoidance zone proximity detection. Avoidance zone proximity detection uses the two blade tip points and the "Ripper back from cutting edge" measurement. The proximity of any one of the four points to an avoidance zone triggers a warning alarm. The "Avoid. Dist" text item displays the shortest distance between any point and the closest avoidance zone.
Warnings start when it has been detected that the machine is within three times of the warning distance that has been set. The following actions occur in a warning at this level:
- The avoidance zones within the detection zone turn magenta in color.
- The "Avoid. Dist." text item gives the distance and direction to the closest avoidance zone.
When the machine is detected to be within the set warning distance, the following extra warning measures are implemented.
- A sequence of three beeps sound.
- In the plan view, a warning symbol is displayed on the machine icon.
- The avoid indicator appears in the bottom right corner of the main views.
Finally, when a machine enters an avoidance zone the following warning measures occur:
- A flashing message "Avoid. Zone Entered" appears. The message has a yellow background.
- Constant beeping sounds until you exit the avoidance zone.
- The "Avoid. Dist." text item shows a negative value.
If the avoidance zone guidance is not available, the "No Avoid" indicator appears in the bottom right hand corner of the main views.
Note: Use AccuGrade Office Software in order to review and test that the avoidance zones are correctly defined before exporting the data to a data card.
Note: SiteVision Office Software can also be used instead of AccuGrade Office Software.
Refer to the Operation and Maintenance Manual for the AccuGrade System for more details on avoidance zones.
Setting the Warning Distance
You need to be in Service Mode in order to access the avoidance zone setting in the "Setup Menu" dialog.
Perform the following steps in order to access the "Avoidance Zone" dialog.
- From the "Setup Menu – Configuration" dialog, press the down arrow key or the up arrow key until "Avoidance Zone" is highlighted.
- Press the "OK" key. A dialog that is similar to Illustration 1 appears.
- Do one of the following.
- Press the arrow keys in order to set the warning distance.
- Press the "Default <value>" soft key in order to set the default warning distance for the selected machine type.
- Press the arrow keys in order to set the warning distance.
