Robot lawnmower shows E06 No Loop Signal when approaching the boundary; mower stops and will not continue.

Safety first: Turn OFF the mower and disconnect power to the charging station before touching any wiring.

• Inspect boundary layout: Ensure the boundary wire is installed according to NAC spacing guidelines from obstacles and metal fences. Too close to metal can distort the signal.
• Check all connectors: Open any junction boxes or connector points. Replace corroded or non‑gel‑filled connectors with NAC‑approved waterproof connectors.
• Shorten test loop: To isolate the problem, create a small temporary loop (5–10 m) directly at the charging station using a spare piece of NAC boundary wire. If E06 disappears with the test loop, the fault is in the lawn wiring.
• Check for parallel power cables: If the boundary wire runs parallel and close to mains cables, reroute it further away to reduce interference.
• Evaluate base unit: If E06 persists even with a short test loop, the boundary signal amplifier or main board in the charging station may be defective and require replacement.

Warning: Never connect the boundary wire to household mains. Only use the NAC charging station output.
