Problems Caused by Boundary Wire Faults - Adano RM5 / SMART 365 500m²

Common Faults and Troubleshooting

Error Codes and Messages:
Robotic lawn mowers often display specific error codes related to boundary wire issues or when the robot's operation is obstructed.

Note that the indicator light on the charging station should be steadily green. If it flashes red, this indicates poor connections or a break in the wire.

1. No signal detected – E11
   • Cause: Wire break or faulty connection.
   • Solution:
     1. Inspect the wire for visible damage or breaks.
     2. Use a cable tester to locate the break.
     3. Repair using waterproof connectors or repair kits.
2. “Weak signal”, the machine makes periodic errors, sometimes runs in circles and stops midway on the lawn due to lack of signal from the boundary wire.
   • Cause: Long cable runs, interference, or moisture.
   • Solution:
     1. Start by checking the machine’s driving log in the app for error messages. If related to the boundary wire, proceed with the following points.
     2. Verify that the total cable length does not exceed the manufacturer’s limits.
     3. Check whether nearby devices are causing electromagnetic interference.
     4. Check for moisture in connectors or cables, as this can cause oxidation and signal problems. Replace defective connectors and repair damaged cable areas.
     5. Tighten the boundary wire behind the charging station.
     6. Avoid excess boundary wire being coiled behind the charging station.
     7. Ensure the boundary wire is not placed too close together to avoid signal interference (see the manual for the recommended distance for your model).
3. “Lawn mower running outside the area” – E1
   • Cause: Incorrect cable placement or signal interference.
   • Solution:
     1. Adjust the boundary wire to ensure proper coverage.
     2. Check if similar products are installed in the area as they may cause signal interference, e.g., at a neighbour’s property. Adjust the distance between boundary wires and charging stations according to your model’s manual.
4. “Intermittent connection”
   • Cause: Loose joints or physical damage to the boundary wire.
   • Solution:
     1. Repair breaks in the wire again.
     2. Replace worn or corroded connectors.
     3. Check the output terminal and ends of the boundary wire for corrosion/rust.

       5. Alternative Solutions
                      Check the charging station for insects:

1. Insects can often find their way into the charging station, which can cause blockages or disturbances in its function. The inspection should include the following:
2. -Inside the charging station: Check for cobwebs, dead insects, or live pests that may affect the electrical components.
3. -Ventilation openings: Ensure that the ventilation openings are free from blockages such as insects or dirt.
4. -Charging points: Inspect the charging contacts for insect residues that may prevent proper charging.
5. -General area around the charging station: Inspect the area around the station for insect nests or signs of activity that could lead to recurring problems.

Note! An effective method for diagnosing boundary wire faults is to set up a test area (approx. 2 m x 1.5 m) in a small size and test the robot within this area.
If the machine works well in the test area, the fault is likely in the boundary wire in the garden.
