Green LED double flash

Green LED double flash — Weak loop signal

husqvarna · Automower Technical Manual

What does Green LED double flash mean?

The green LED on the charging station is flashing twice every other second, indicating a weak boundary loop signal. This may be due to the wire being too long or damaged.

Common Causes

  • Boundary wire is too long (beyond 500 meters).
  • Boundary wire is damaged.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Consider installing a Signal amplifier (522 42 58-01), available as an accessory, if the loop is longer than 500 meters (up to 800 meters).

  2. 2

    Check the boundary wire for any damage or breaks that might be causing signal weakening.

  3. 3

    If possible, reduce the overall length of the boundary wire to improve signal strength.

  4. 4

    Ensure all boundary wire connections are secure and free from corrosion.
