ELBOW 0016873 - Caterpillar

Introduction
By default, the "Lightbar Scales" option is available for all configurations of 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 dialogs set the vertical and horizontal tolerances that apply to the LEDs 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 LEDs will be lit. A tolerance threshold for horizontal light bars is the distance off-line at which two LEDs will be lit.When the blade 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 blade moves offgrade (off-line), additional LEDs are lit.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 blade is considered to be on-grade. When the blade is in the on-grade range, the Cut/Fill text items and the associated direction arrow are green.When the blade 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.
