Troubleshooting

Error Messages and Solutions

• Shock Absorber Error: Ensure nothing is obstructing the machine.

• Emergency Stop Activated: To restart the machine after an emergency stop, rotate the emergency stop button a quarter turn counterclockwise to reset it.

• Boom Sensor: The boom is likely in too low a position. Raise the boom manually via the app on the tablet. The boom can then operate autonomously again.

• Too Large an Angle to the Next Point During Autonomous Driving, Cannot Find the Next Point: Manually drive the machine to a point where it can be activated.

• Low Voltage: The robot may experience low voltage even if the generator is on. This indicates the machine has been working too hard. Let the machine rest with the generator running for a few minutes. Then attempt to resume work with the machine running at a slower speed.

• GPS Missing RTK: The GPS requires access to Real-Time Kinematic (RTK) positioning for the machine to operate autonomously. Allow the machine to remain stationary until the GPS regains the RTK signal. The machine will automatically resume work once the signal is restored. Alternatively, the machine can be operated manually via the Kilter Remote application until RTK is restored.

Clearing Blockages in the Fluid System

Blockages in the fluid system can occur for various reasons, such as debris or dried spray agent obstructing the flow, or improperly connected hoses. Below is a general procedure for troubleshooting and removing blockages:

• Step 1: Check that all spray units are properly connected as described in Section 4.4 Spray Unit.
• Step 2: Verify that all valves are in the correct position as described in Section 4.2.6 Valve Positions.
• Step 3: Check the spray pressure in the Kilter Remote application and the pressure gauge (see Figure 12 – Other Components of the Fluid System) to determine if the pressure readings indicate the location of the blockage.
• Step 4: Clean the suction filter of the fluid system as described in Section 9.5 Suction Filter.
• Step 5: Clean the filters of the spray units as described in Section 9.4.1 Filter for Spray Unit.
• Step 6: Perform a nozzle cleaning procedure in the Kilter Remote application.
• Step 7: If blockages persist in the spray system, contact your Kilter representative for further assistance.

Spray Liquid Does Not Circulate

This issue could result from one or more of the following causes:

• The tank is empty. Refill the tank with spray liquid.
• The pump is not drawing. Check in the Kilter Remote application that the pump is turned on.
• Clean the suction filter of the fluid system as described in Suction Filter.
• Verify that all spray units are properly connected as described in Spray Unit.
• Clean the filters of the spray units as described in Filter for Spray Unit.
• Verify that all valves are in the correct position as described in Valve Positions.
• Check the spray pressure in the Kilter Remote application and the pressure gauge to identify potential blockages.
• If the spray liquid still does not circulate, contact your Kilter representative for further assistance.

Pressure Is Not High Enough

This issue could result from one or more of the following causes:

• There may be a leak in the spray system. If there is a leak, stop the pump immediately.
• The tank is empty. Refill the tank with spray liquid.
• The pump is not drawing. Check in the Kilter Remote application that the pump is turned on.
• Clean the suction filter of the fluid system as described in Section 9.5 Suction Filter.
• Verify that all spray units are properly connected as described in Section 4.4 Spray Unit.
• Verify that all valves are in the correct position as described in Section 4.2.6 Valve Positions.
• If the pressure remains low, contact your Kilter representative for further assistance.

Robot is driving out of the tracks

If the robot keeps driving out of the tracks, this could be because the segment it follows is a bit off. Open the route editor, and shift the current segment using the "Shift Segment" button. If the robot keeps driving out of the field to the right, shift the field to the left and vice versa. Please refer to the help section of KilterRemote app under "Route Editor" for more information.

Other Troubleshooting in the Field

• Tablet/Mobile Device Cannot Connect to the Robot

  • Check if Wi-Fi is enabled on the tablet/mobile device.
  • Verify that the AX-1 is turned on and has power.
  • It may take up to 2 minutes after powering on the machine to establish a connection.
  • Ensure you have the correct username and password for logging into the Kilter Remote application.

• Generator Stops or Won’t Start

  • Check the fuel level. Refer to the generator’s user manual.
  • Ensure the choke is turned off after starting.

• Nozzles Are Spraying Excessively

  • Verify that the spray pressure is correct.
  • Check that all spray modules have hoses and cables connected to the correct ports.
  • Confirm in the Kilter Remote application that all spray modules have the correct status (green, not red) and proper numbering.
