By default, the GPS Accuracy Mode is available for all configurations of the AccuGrade System. Depending on the operator configuration settings for your system, some of the options, soft keys, or views discussed in this manual may not be accessible.Use GPS Accuracy Mode in order to set the maximum GPS error estimate that is acceptable for your application.If the GPS error estimate exceeds the limits defined for the selected mode, a "Low Accuracy GPS" message is shown on the Display.There are three GPS Accuracy modes:
Fine
Medium
CoarseYour supervisor sets the limit for each mode. Your supervisor sets each mode to suit the type of work you are doing. (Your supervisor can also deactivate the modes.) For example, the limits for Fine mode are set for finish trim work. If GPS accuracy is not within the tolerance set for Fine mode, do not change into Coarse mode in order to continue work on your final trim surface. Instead, do one of the following things:
Wait for the GPS accuracy to improve and then continue in Fine mode.
Change the GPS Accuracy mode and then continue working on an area that does not require Fine mode GPS accuracy.
Change the GPS Accuracy mode and then raise the vertical offset in order to leave the constructed surface high. Return to the area when the GPS accuracy has improved and allows Fine mode operation. This allows you to continue working on the same area of the design and not overcut the final design surface.If you are using one or more GPS Receivers as position sensors, make sure that the selected GPS accuracy mode is appropriate for the work that you are about to do.Refer to the GPS Accuracy Mode Set Section of this manual for additional information.Valve Speed
Correct valve speeds depend on the type of material that you are moving (for example, sand, hard rock, or dirt) and what tasks you are doing (for example, base grade or finished grade).
Once the system is placed in automatic mode, blade movement may occur.Ensure that all personnel are clear of the blade before you place the system in automatic mode.Personal injury or death from crushing could occur.
Refer to the Valve Speed Set Section of this manual for additional information.Lightbar Tolerances
The lightbars on-grade tolerance are adjustable in order to provide the appropriate guidance for the Design Surface.Refer to the Light Bar Scale - Set section of this manual for additionally information.Blade Wear
As you operate the machine, the cutting edge of the blade wears away. This feature allows the measurement of the cutting edge to be updated.Refer to the Blade Wear - Set section of this manual for additional information.Mast(s) Vertical
