On-screen Lightbars

Lightbars provide you with guidance information. They enable you to view the guidance information, attachment, and the surface you are working all at the same time.

TIP – Lightbars provide guidance to designs or alignments, they do not provide guidance to a point.

The Lightbars screen

Use the Lightbars screen to select the guidance that you want. You can access the Lightbars screen from the System Settings menu.

The screen shows the current lightbar configuration.

There are also options for the left, center and right lightbars. Use the toggle to turn the lightbars on and off.

Understanding lightbar information

The on-screen lightbars appear along the left, top, and right edges of the display, depending on your system configuration.

The following table describes the different items in the left/right on-screen lightbars:

Item   Function
Live location arrow The arrow moves along the lightbar, tracking changes in the position of the cutting edge. It shows whether the current position is cut, fill or on grade in relation to the design or target surface.
Cut

The cut zone is red, and is above the on grade tolerance zone.

The cut zone is active when the current position of the cutting edge is above the design or target surface.

On grade tolerance

or

The on grade tolerance zone is always bright green.

NOTE – To change the on‑grade tolerance zone, go to System Settings > Grade Tolerance.
Fill

The fill zone is blue, and is below the on grade tolerance zone.

The fill zone is active when the current position of the cutting edge is below the design or target surface.

The lightbars behave differently depending on the mode you are working in.

The following tables describe what the lightbars display for each mode.

Depth and Slope mode

  • Amber (left of center) – curl the attachment out (dump) away from the cab.
  • Green – the bottom of the attachment is parallel to the design slope.
  • Amber (right of center) – curl the attachment in towards the cab.
Right lightbar

Useful text items

  • Cut/Fill Left
  • Cut/Fill Center
  • Cut/Fill Right
  • Offline

NOTE – If the text item value is Cut then the icon in the text item shows a red arrow; if it is Fill it shows a blue arrow; and if it is within the on grade tolerance it shows a green arrow.

System buzzer

When the lightbars are in Cut/Fill Left and Cut/Fill Right, the system buzzer Cut/Fill is determined on the attachment tip that is farthest from design. Both tips need to be within grade tolerance for the buzzer to sound.

Troubleshooting

The lightbars are disabled if there is no guidance available, for example if the elevation is not benched. When the lightbars are disabled, they appear as follows:

  • The location arrow does not appear
  • The lightbars are grayed-out
  • The Cut/Fill or Offline text items do not show any values
