Autos Setup on Cat D6 and D7 machines

When you engage Autos the system automatically controls lift and tilt movement of the blade.

Autos status indicators

The Autos status indicators at the bottom corners of the work screen show you what state Autos are currently in. The Blade Lift status indicators are on the left–hand corner and the Blade Tilt status indicators are on the right–hand corner of the screen.

Engaging Autos

To use Autos:

1. Load a design or have a benched surface to guide to.

2. Make sure the machine’s hydraulic oil is at its normal operating temperature.
3. Turn the throttle up to maximum revs. If your machine has Eco‑mode, turn it off.

4. Position the blade within the control range.

   TIP – Use the lightbars, cut/fills and buzzer to assist you to position the blade within the control range. The Control Range is also available as a text item.

5. Access the Autos Setup screen via the Work Settings menu.

6. In the Autos Setup screen, select the Autos mode you require and tap Apply.

   • Latch to Grade (default): the system controls the blade when either blade tip is on grade.

   • Snap to Grade: the system controls the blade when both blade tips are within the auto controls range limit.

   NOTE – If you are using the AutoCarry feature in conjunction with Autos, the feature with the largest raise command or the smallest lower command takes control of the blade, with the exception that Autos (Grade Control) will not allow the blade to cut below design without a deliberate manual joystick command to over‑ride Autos. See the Best Practices when using Autos guide for more information.

7. Exit to the work screen.

8. For Snap to Grade—Press the auto switch as the cutting edge approaches the design elevation to engage Autos.

   NOTE – Each press of the auto switch will cycle between Autos and Manual.

   

   To switch off Autos and return to Manual, press the auto switch or you can temporarily over‑ride Autos by moving the joystick while you are in the Autos control window. Be aware that while Autos is disengaged you can cut beneath the design. Sometimes you may purposefully want to cut below design, however if this is not the case make sure that you monitor your cut/fills and lightbars.
   To re‑engage Autos, press the auto switch again or if you temporarily over–rode Autos then return your joystick to the neutral position.

9. For Latch to Grade—Drive the machine onto design and when either blade tip is on grade the system will go into the Autos Engaged state. You can temporarily over‑ride Autos by moving the joystick. This will put the system into the Autos Ready state. Now put the joystick into neutral and move the joystick in the desired direction again to start driving the blade manually.

Select and Apply a Preset

You can select and apply the active preset via the Autos Setup or Autos Optimization screen. You can access these screens via the Work Settings menu. There is always at least one preset stored which is the Default preset set by your technician in the Web Interface. This cannot be edited or deleted.

Select the active preset that you require and tap Apply.

You can create, edit or delete a preset via the Autos Optimization screen. For more information, see Autos Optimization.
