Tilt Autos Setup on Cat NGH mini/micro machines

Tilt Autos performs best when grading a finish surface. After you finish bulk excavating and approach final grade, engage Autos. The system automatically controls movement of the attachment tilt, while you manually control movement of the rest of the front linkage.

Tilt Autos can automatically move the tilting attachment at rotation angles 70° from forward and 70° from backwards. The tilt cylinders do not rotate with the attachment, so outside of this range the cylinders drive attachment dump/curl instead of tilt. If the attachment falls outside this range, you get the message: Attachment tilt is outside of measurable range.

Tilt Autos status indicators

The Tilt Autos status indicators at the bottom left–hand corner of the work screen show you what state Autos are currently in.

Enable and Engage Tilt Autos

To use Tilt Autos:

1. If you are in Depth and Slope mode, bench the machine before you use Tilt Autos.

   If you are in Design mode, load a design before you use Tilt Autos.

2. Position the machine on solid, stable ground to prevent rocking.

3. Make sure the machine’s hydraulic oil reaches its normal operating temperature (55°C/130°F).

4. Select High Power mode and turn the throttle up to maximum revs.

   NOTE – You can use the auto idle function on your machine.

5. Position the attachment within the control range.

   TIP – Use the lightbars, cut/fills and buzzer to guide the attachment.

6. If you are using a non‑integrated tiltrotator:
   1. Toggle off Grade Enable via the Cat Machine Display.
   2. Access the Autos Setup screen via the Work Settings menu.
   3. In the Autos Setup screen, toggle Arm Tilt Autos on and tap Apply.
   4. To engage Tilt Autos: Press and hold the Tilt Autos switch as the attachment cutting edge approaches the design elevation. If the attachment is in the controls range it will start automatic movement of the attachment as you move the stick lever.
7. If you are using an integrated tiltrotator:
   1. Set the Grade Configuration to Tilt Only and toggle on Grade Enable via the Cat Machine Display.

   2. Press the Grade Auto switch and acknowledge the Grade Enable message on the Cat Machine Display.

      

   3. To engage Tilt Autos: Press and hold the Grade Auto switch as the attachment cutting edge approaches the design elevation. If the attachment is in the controls range it will start automatic movement of the attachment as you move the stick lever.

      To temporarily disengage Tilt Autos: Let go of the Grade Auto switch. Be aware that while Tilt Autos is disengaged you can cut beneath the design. Sometimes you may purposefully want to dig below design, however if this is not the case make sure that you monitor your cut/fills and lightbars. Press and hold the Grade Auto switch again to re‑engage Tilt Autos.

      You can manually override Tilt Autos at any time by moving the attachment.

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 Tilt Autos Optimization on Cat NGH mini/micro machines.
