Tilt Autos Setup

TIP – For optimum performance when using Autos features, avoid connecting the Operator App device to the system via Wi-Fi. Ensure that you use a wired connection.

NOTE – For Trimble Autos on Cat NGH series 07 machines or Cat NGH mini/micro machines, see Using Autos on other machine models.

NOTE – If you want to use Depth and Tilt Autos together, see Depth and Tilt Autos Setup.

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.

NOTE – This does not apply if you have an integrated engcon tiltrotator or an engcon tiltrotator with protocol ePS 2.0.

TIP – For information on best practices, see Best Practices When Using Tilt Autos.

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.

If you use Tilt Autos without Depth Autos on an engcon tiltrotator, the system will not have any pilot pressure information and will not be able to detect a hydraulic lockout. The status indicator will remain as Autos engaged instead of changing into Manual interlock.

Status indicator Status

Manual

Tilt Autos is armed, but not engaged.

Manual interlock

Tilt Autos is armed but cannot be engaged.

Possible reasons: Tiltrotator function not currently supported, auto state in fault.

Tilt Autos ready

Tilt Autos is armed and engaged, but is not active because the attachment is outside the control range.

Tilt Autos engaged

Tilt Autos is armed, engaged and active with the attachment inside the control range.

In this state the system controls movement of the attachment.

Tilt Autos not ready

Tilt Autos is armed and engaged but cannot be active so Autos is temporarily suspended.

Possible reasons: GNSS precision is outside tolerance, attachment is off design.

Arm and Engage Tilt Autos

WARNING – When Tilt Autos is engaged, the system will control movement of the attachment tilt. These movements could cause injury to anyone near the attachment, or damage to the machine. Always put the attachment on the ground and engage the hydraulic lockout before you leave the machine.
Do not use Tilt Autos when somebody is working near the attachment or if the ground conditions are unstable. Only use Tilt Autos to grade a finish surface. Disarm Tilt Autos when you perform other applications, such as lifting.

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. Enable the Auto function on the tiltrotator controller.

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

  8. Arm Autos: In the Autos Setup screen, select Tilt as the auto mode. Toggle Arm Autos on and tap Apply.

    A 30 second timer displays.

  9. Confirm Autos: Press and hold the tilt auto switch (as per your tiltrotator manufacturer instructions) for more than one second, and then release it.

  10. Engage Autos: Press and hold the tilt auto switch as the attachment cutting edge approaches the design elevation.

    To temporarily disengage Tilt Autos, let go of the tilt auto switch. Be aware that while Autos is disengaged you can cut below 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 the tilt auto switch again to re‑engage Tilt Autos.

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.

Troubleshooting

The table below lists some of the error messages that may appear when you use Autos. You may need to enlist the help of your technician to resolve the error states.
