Error Messages and Troubleshooting - Garden 1200m2 APP Control

On the error indicator light, you can see what might be wrong if the robotic lawnmower has stopped.

    Meaning of the indicator light on the charging station

• Green light: The boundary wire is correctly connected, the robotic lawnmower is ready, and the battery is fully charged.
• Flashing green: There is a break in the boundary wire. The ends of the boundary wire are connected incorrectly on the charging station. Correct the error.
• Red light: The battery is charging.
• Flashing alternately green and red: Maintenance charging of the battery (trickle charging).

        Note! If the error indicator light on the robotic lawnmower flashes red, there may be problems with the boundary wire signal:

• The robot is outside the boundary wire.
• The boundary wire is too long (over 250 m).
• The boundary wire is incorrectly joined, there is moisture in a joint, or an incorrect connector has been used.
• The boundary wire MUST NOT be stripped when using connectors.

Error Indicator Light:

Red light on: 

 The robotic lawnmower is lifted

• The robotic lawnmower reports an error if the lift sensors are continuously activated for 10 seconds. If the robotic lawnmower reports an error due to the lift sensors, press the "OK" button to restart it.
• If the error occurs repeatedly, check the working area.
• Make sure to remove obstacles higher than 100 mm that the robotic lawnmower can drive onto.
• Use a conventional lawnmower to cut grass higher than 60 mm.

The robotic lawnmower is stuck

• If the obstacle sensors are activated more than 5 times in one minute, the robotic lawnmower will report an error.
• Press the "OK" button to restart the robotic lawnmower.
• If the error occurs repeatedly, check if the boundary wire is correctly laid out. The error often occurs in places that are too narrow or cramped for the robotic lawnmower to continue after changing direction.
• Check for obstacles such as branches or similar that may restrict the robotic lawnmower's freedom of movement.

Error with the shield

• There are four magnets in the robotic lawnmower's shield. If there is metal between the magnets and the shield, it can cause errors.
• Remove any metal pieces from the magnets and restart the robotic lawnmower.

Flashing red:

 Error with the boundary wire signal

• The robotic lawnmower turns around on the spot, stops, and reports an error if it has gone outside the working area or if there is an error with the boundary wire.
• Ensure that the entire robotic lawnmower is within the defined working area. If it is outside, it cannot find the signal or drive back to the charging station.
• Walk along the wire and look for breaks or damage. If the wire is damaged, it must be repaired or replaced.
• Look at the indicator light on the charging station. If it flashes green, this may indicate a problem with the wire.
• Remove the ends of the boundary wire from the charging station and measure the resistance of the wire with a multimeter. A new wire has about 2 Ohms per 100 metres.

If the resistance is more than 8-10 Ohms, the wire must either be repaired or replaced.

Blue light on:

Battery error

• If the robotic lawnmower reports an error, it may be due to a defective battery.
• Replace the defective battery with a new original battery with the same specifications.
• If the robot's battery indicator lights red, the battery is simply discharged.
• Place the robotic lawnmower on the charging station and perform a manual charge.

Flashing blue:

Abnormal battery temperature

       Note!  The robotic lawnmower reports an error if the battery temperature during operation goes outside the range 0-75 °C or during charging outside 0-45 °C.

• If this happens, the robotic lawnmower returns to the charging station to charge the battery and achieve a safe temperature.
• The risk of errors is highest in summer, especially if the outdoor temperature approaches 35 °C in the sun.
• To avoid this problem, it may be beneficial to change the robotic lawnmower's start time to earlier in the day when the temperature is lower.

Charging error

• Ensure that the charging contacts on both the charging station and the robotic lawnmower are clean. Use a dry cloth to wipe them if they are dirty.
• Check that the charging contacts correctly engage with the charging plug on the robotic lawnmower. They should be firmly in place and have good contact.
• If the battery is completely flat, it may be necessary to perform a manual charge.

        Note! Procedure for manual charging

• Pull the robotic lawnmower out of the charging station.
• Set the main switch to the OFF position and wait 5 seconds.
• Set the main switch to the ON position and push the robotic lawnmower back into the charging station.
• DO NOT turn on the robotic lawnmower using the Power button.
• The indicator light on the charging station may take up to 1 hour to change to red if the battery voltage is very low.
• When the indicator light turns green, charging is complete and the robotic lawnmower is fully charged.

Overheating of the circuit board

• The robotic lawnmower reports an error if the circuit board overheats. The robotic lawnmower returns to the charging station to achieve a stable temperature.
• The risk of this is greatest in summer if the outdoor temperature approaches 35 °C in the sun. It may be beneficial to change the robotic lawnmower's

start time so that it starts earlier in the day when it is not yet so hot.

The robotic lawnmower has tipped over

• If the robotic lawnmower tips over, it stops and reports an error.
• Turn the robotic lawnmower upright and press "OK" to restart it.
• If the error is due to a steep slope, change the boundary wire routing to avoid this.

The robotic lawnmower is overloaded

• The motors of the robotic lawnmower are protected against overload. If this error occurs, it is probably because the grass is too high for

the robotic lawnmower, or the cutting disc and wheels are blocked by cut grass, mud, or similar.

• Cut tall grass with a conventional lawnmower and clean the robotic lawnmower.

There is an obstacle on the boundary wire

• If an obstacle on or near the boundary wire prevents the robotic lawnmower from driving onto the charging station, it will try several times and then stop.

Remove the obstacle.
