Tolerance Range
The tolerance range for the vertical Light Bars is the distance off grade when two of the LED indicator lights on the Light Bar are illuminated. A tolerance range for horizontal Light Bars is the distance off the line when two of the LED indicator lights on the Light Bar will be illuminated.When the blade is on grade and the blade is within half of the tolerance range, the center green LED indicator light on the appropriate Light Bar is illuminated. As the blade moves off grade, additional LED indicator lights are illuminated.When the blade is on-line and the blade is within half of the tolerance range, the center green LED indicator light on the appropriate Light Bar is illuminated. As the blade moves off-line, additional LED indicator lights are illuminated.Other distances for the LED indicator lights are automatically adjusted from the tolerance range.The vertical tolerance range also determines the on-grade tolerance. The on-grade tolerance is the vertical range when the blade is considered to be on-grade. When the blade is in the on-grade range, the "Cut/Fill" text field and the associated direction arrow are green.When the blade is out of the on-grade range, one of the following events will occur:
The "Cut" text field and the down arrow will be red.
The "Fill" text field and the up arrow will be blue.
