Introduction
By default, the "Light Bar Scales" option 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.Operate to an on-grade tolerance threshold appropriate for the design surface. The "Light Bar Scales" dialog sets the vertical and horizontal tolerances that apply to the LED indicators on the light bars. The horizontal and vertical light bars are set independently of each other.Tolerance Thresholds
A tolerance threshold for vertical light bars is the distance off-grade at which two LED indicators will be illuminated. A tolerance threshold for horizontal light bars is the distance off-line at which two LED indicators will be illuminated.When the bucket is on-grade (on-line) to within half the tolerance threshold, only the center green LED on the appropriate light bar is lit. As the bucket moves offgrade (off-line), additional LED indicators are illuminated.Other LED distances are automatically scaled from the tolerance threshold.The vertical tolerance threshold also determines the on-grade tolerance. The on-grade tolerance is the vertical range where the bucket is considered to be on-grade. When the bucket is in the on-grade range, the "Cut/Fil"l text items and the associated direction arrow are green.When the bucket is out of the on-grade range, one of the following things will occur:
The Cut text item and the down arrow will be red.
The Fill text item and the up arrow will be blue.Setting the Light Bar Scales
In order to set the tolerance thresholds, complete the following steps:
From the "Setup Menu – Configuration" dialog, press the down arrow or the up arrow until "Light Bar Scales" is highlighted.
Press the "OK" key. Refer to Illustration 1.
Illustration 1 g01261114
In the "Light Bar Scales" dialog, press "Vertical" in order to set the vertical light bar scale. Use any of the following tools to edit the vertical tolerance value:
If you work in meters, press "Default Set 0.050" to set your tolerance to the default value of 0.050 m. If you work in US FT or feet, press "Default Set 0.200".
Use the arrow keys to enter the off-grade distance at which two vertical LED indicators are illuminated. Enter a value between 0 and 3.810 m. The remaining threshold values are calculated automatically and appear in the dialog.
Press "Half Set 0.025" to set your tolerance to half of the current tolerance.
Press "Double Set 0.100" to set your tolerance to double the current tolerance.This vertical tolerance value is used as the AccuGrade system off-grade limit. If the cut or fill value at either bucket tip exceeds this tolerance for more than three seconds, then the bucket is considered to be off-grade.
Press the "Horizontal" soft key in order to set the horizontal light bar scale. Use any of the following tools to change the horizontal tolerance value:
If you work in meters, press "Default Set 0.100" in order to set your tolerance to the default value of 0.100 m. If you work in "US FT" or feet, press "Default Set
