No loop signal — Boundary wire or power issue

What does No loop signal mean?

The robotic mower cannot detect the boundary wire signal. This often indicates a power problem with the charging station or a break in the boundary wire. Check the charging station's LED status for more clues.

• The power supply or low-voltage cable is not connected or is damaged.
• The boundary wire is not connected to the charging station or is broken.
• ECO mode is activated and the product attempted to start outside the charging station.
• Boundary wire is crossed around an island or the product is too far from the wire.
• Disturbances from metal objects (fences, reinforcement steel) or buried cables nearby.

Click steps to track your progress.

1. 1

   Examine the LED status on the charging station. If the LED is not lit, check the power outlet connection and if a residual-current device is engaged.

2. 2

   Make sure the low-voltage cable is connected to the charging station. Replace the power supply or low-voltage cable if damaged.

3. 3

   Ensure boundary wire connectors are fitted properly to the charging station. Replace connectors if damaged.

4. 4

   If the charging station LED indicates a boundary wire break, locate and replace the damaged section using an original coupler.

5. 5

   If ECO mode is active, place the product in the charging station and start it. Generate a new loop signal if needed.

6. 6

   Check the boundary wire layout to ensure it's not crossed, especially around islands, and that the product is within 35 m / 115 ft of the wire. Consider moving the boundary wire or creating more islands if disturbances are suspected.
