Understanding the Boundary Wire - Adano RM5 500m2

Understanding the Boundary Wire

The boundary wire (edge wire) defines the mower's working area and ensures efficient operation by preventing it from leaving the designated area.
It creates an electromagnetic signal that is picked up by the mower's sensors.

Key Components:

• Boundary Wire: Installed along the perimeter of the working area.
• Signal Generator: Located in the charging station; emits the boundary signal.
• Connectors and pegs: Used to secure the wire in place.

Installation Checklist:

1. Plan the layout:
   • Identify obstacles such as trees, flower beds, or paths.
   • Avoid sharp angles; use gentle curves at corners.
   • Mark off designated areas such as pools or steep slopes.
2. Install the wire:
   • Lay the wire flat on the ground, bury it, or place it under paving stones if necessary (up to 5 cm deep).
   • Ensure a complete loop to the charging station.
   • Use pegs to secure the wire at regular intervals (every 30-50 cm).
   • Ensure there are no loose sections to prevent the mower from getting stuck.
   • Be careful not to damage the wire when hammering in the pegs. Excessive hammering can cut the wire and cause faults.
3. Connect to the station:
   • Connect the ends of the boundary wire to the designated ports on the charging station (follow IN and OUT, and ensure the station is positioned correctly).
   • Test for a stable signal before starting the mower – the charging station's indicator should light up green.

Common Errors and Troubleshooting

Error Codes and Messages:
Robot mowers often display specific error codes related to issues with the boundary wire or the robot's work being obstructed.

Note that the indicator light on the charging station should be constantly green. If it blinks red, it is a sign of poor connections or a break in the wire.

1. No signal detected – E11
   • Cause: Break in the wire or faulty connection.
   • Solution:
     1. Inspect the wire for visible damage or interruptions.
     2. Use a wire tester to locate the break.
     3. Repair using waterproof connectors or splice kits.
2. “Weak signal”, the machine experiences periodic faults, runs in circles sometimes, and stops in the middle of the path due to lack of signal from the edge wire.
   • Cause: Long wire runs, interference, or moisture.
   • Solution:
     1. Start by checking the machine's driving log in the app for error messages. If it is related to the edge wire, proceed with the following points.
     2. Check that the total wire length does not exceed the manufacturer's limits.
     3. Investigate if nearby devices are causing electromagnetic interference.
     4. Check for moisture in connectors or wires, as this can cause oxidation and signal issues. Replace faulty connectors and repair damaged wire areas.
     5. Tighten the edge wire behind the charging station.
     6. Avoid excess edge wire coiled up behind the charging station.
     7. Ensure that the edge wire is not lying too closely together and interfering with the signal (refer to the manual for the recommended distance for your model).
3. “Mower running outside area” – E1
   • Cause: Incorrect wire 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 create signal interference, e.g., at a neighbour's. Adjust the distance between edge wires and charging stations according to your model's manual.
4. “Intermittent connection”
   • Cause: Loose connections or physical damage to the edge wire.
   • Solution:
     1. Repair the breaks in the wire again.
     2. Replace worn or corroded connectors.
     3. Check the output terminal and the ends of the edge 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 disruptions 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 remnants of insects that may hinder proper charging.
5. -Overall around the charging station: Inspect the area around the station for insect nests or signs of activity that may lead to recurring problems.

Note! A test area is an effective method for diagnosing faults in the edge wire is to build a test area (approximately 2 m x 1.5 m) in small size and try the robot within this area.
If the machine works fine in the test area, the fault is likely in the edge wire in the garden.
