AccuGrade® Version 11 Compaction GPS Mapping and Measurement System Caterpillar

The "Select Design" option is used for the following purposes:

• Select a design to use for guidance

• Create a design if there are no listed designs.

In order to perform either of these actions, perform the following steps:

1. Ensure that there is a data card inserted in the Display.

   Illustration 1 shows the physical layout of the AccuGrade Display. Refer to this Illustration for the location of the keys that are discussed within this section.

5. Perform one of the following actions:
   • Select a design. Use the arrow keys (9). Press the OK key (10). You are returned to the "Setup Menu - Configuration" screen.

   • If the only entry in the list is "[None]", then you must create a valid design.

Creating a Design

A valid design can be created by using one of the following soft keys:

• New Level

• New Slope

• New Map

Once a valid design has been created, the "Vertical Offset" and the "Horizontal Offset" dialogs are available.

New Level

In order to create a design by using the current elevation of the machine, complete the following steps:

1. From the "Select Design File" dialog, press the "New Level" soft key. The "New Design: Level Surface" dialog appears.

7. Press the OK key (10). The "Setup Menu - Configuration" screen appears. The design that you selected appears to the right side of the "Select Design:" text.

8. Press the Escape key (5). A guidance screen appears.

New Slope

The following methods can be used in order to create a sloping surface design file:

• Two Points Method: using the "Method: 2 Points" soft key

• Point and Direction Method: using the "Method: Pt/Dir" soft key

The "Two Points" method and the "Point and Direction" method update each other with information. The "Point 1" value and the "Cross Slope" value are always the same in either method. The System uses these values in order to calculate the direction and the grade.

Note: If you change the "Direction" setting or the "Grade" setting using the "Pt/Dir" soft key, then the change clears the value of "Point 2" in the "2 Points" method. This occurs because there is not enough information for calculating the new position.

In order to create a sloping surface design file, complete the following steps:

1. From the "Select Design File" dialog, press the "New Slope" soft key. The "New Design: Sloping Surface" dialog appears.

Show/hide table

2. The dialog contains the soft keys and the fields that are needed to define a sloping surface with the "2 Points" method.

3. Specify the value for "Point 1". Refer to the following when specifying the point.
   • Use the next key (4) to move to each of the fields.

   • The "Northing", "Easting", and "Elevation" fields can be edited directly. Use the arrow keys (9) .

   • Change the edge of the drum that has focus. Use the "Drum:" soft key. The key will toggle between "Drum: Left" and "Drum: Right". The displayed value is the edge of the drum that has focus.

   • To use the current position as point 1, press the "Here" soft key. The current northing, easting, and elevations of the drum edge that has focus are loaded into the fields.

4. The "Two Points" method is the default method. If you want to use the "Point and Direction " method to define the surface, go to Step 7.

5. Press the "Point 2" soft key. Use the bulleted items in Step 3 when specifying the second point.

6. Go to Step 12.

9. Edit the "Direction" field in order to specify the direction of the master alignment relative to "Point 1". Use the arrow keys (9) .

10. Press the Next soft key (4). The "Grade" field is highlighted. A "Level" soft key appears.

11. Specify the grade of the master alignments. Use one of the following methods.
    • The "Grade" field can be edited directly. Use the arrow keys (9) .

    • Press the "Level" soft key. The Grade is set to zero percent. The value in the field indicates "Level".

The Cross Slope screen is shown. In Illustration 10 the "Right" field contains a slope of 10 percent. The corresponding figure to the right of this field indicates the direction of the slope as seen by the operator. Note that the Left field contains a slope of 0 percent. The corresponding figure to the right of the field is level.

12. Press the "Cross Slope" soft key. The "Cross Slope" screen appears. A "Level" soft key appears. A "Swap Slope" soft key appears below the "Level" soft key. The "Left" field is highlighted.

13. Refer to the following when specifying the Left cross slope and the Right cross slope.
    • Edit the "Left" and "Right" fields directly. Use the arrow keys (9) .

    • Use the Next key (4) in order to move between the fields.

    • Press the "Level" soft key in order to set the selected cross slope to zero percent.

    • Press the "Swap Slope" soft key in order to change the direction of the cross slope. The symbol that is beside the selected cross slope field indicates the direction of the slope as seen from the position of the operator. If a field contains zero percent, this symbol will be flat. Refer to Illustration 10.

14. Press the OK key (10). The "Design Name" dialog appears. The System assigns a default name to the design.

15. Press the OK key. The new sloping surface design is loaded. The "Select Design File" screen appears. The new name is listed in the "Design Name" field.

16. If you want to use a different name, edit the default name. Use the arrow keys (9).

17. Press the OK key (10). The "Setup Menu - Configuration" screen appears. The slope file that you selected appears to the right of the "Select Design:" text.

18. Press the Escape key (5). A guidance screen appears.

New Map

In order to create a new, empty map directory to hold map recording data, complete the following steps:

1. From the "Select Design" dialog, select "New Map". The "New Map" dialog appears. The AccuGrade System assigns a default name to the map.

2. If you do not want to use this name, edit the default name. Use the arrow keys (9) .

3. Press the OK key (10). The new name is accepted. The "Select Design" dialog appears. The map that was just created is highlighted.

4. Press the OK key (10) in order to load the new map. After the map is loaded, the "Setup Menu - Configuration" screen appears.

   Note: If a New Map is created or if an existing "Map Type" is not selected, then there is no surface design that can be used to determine the cut or the fill. No information is displayed in the Cross Section screen or in the Profile screen. There is no related information for the cut or the fill.

   Note: The difference between a "New Map" and any other design is a reference surface. Every "design" has a reference surface, so cut and fill may be computed and displayed. There may also be linework for horizontal guidance. A "map" has no surface associated with it. In both cases, however, position and compaction data may be displayed and logged.

   Note: This map does not guarantee that Productivity data (*.tag files) are logged. If Productivity data is also required, verify in the "Installation" menu that "Production Reporting" = "Yes".

5. Press the Escape key (5). A guidance screen appears.
