Adaptable Displays
The new software is available for the AccuGrade® Systems on Track-Type Tractors and Series H Motor Graders that are using one of the following Displays:
255-0947 Monitor Display Group
253-5371 Monitor Display Group Note: It is strongly advised that all machines that are equipped with either display in the above list be updated with the new Version 2.51 flash file.New Features and Improvements
The following list contains improvements and features that have been made to Version 2.51 of the AccuGrade Software.
Track Type Tractors and Series H Motor Graders will both use the 255-0947 Monitor Display Group .
System calibrations are not allowed until the machine dimensions have been entered in the "Machine Setup" option of the "Installation" Menu. This reduces the grade errors that were introduced when the default values in the Display were used.
The algorithm that is used in Valve calibration has been improved in order to increase the valve response when the machine is in the Automatic mode.
The response time for the cross coupling feature that is used on Motor Graders has been increased in order to allow faster cross slope response while the machine is grading.
Improved Linked Mode Elevation operation.
The Dip Reduction has been improved. Additionally, this feature can now be turned off.
New Diagnostic Codes have been added in order to aid in troubleshooting the AccuGrade System.Table 1 lists the recommended software versions for the AccuGrade components that are used with AccuGrade System v2.51 software.
