Error message
Error message Possible cause Solution
CN001: Tilt sensor • Maximum gradient exceeded
• Excessively steep slope
Exclude the excessively steep slope from the cutting
area
Robot has been picked up Place the robot on a level surface and reset the error.
CN002: Lift sensor The housing has been displaced in an
upward direction because it has been
lifted or because the mower has run
over an object.
Remove the foreign object.
CN005: Bumper deflected The robot has collided with an
obstacle and is unable to move clear
(collision near the base station).
Remove the obstacle
CN007: No loop signal
CN017: Cal: signal weak
No circuit signal.
Error during calibration, circuit signal
too weak.
• Check base station power supply.
• Check circuit.
• Disconnect and then reconnect the transformer.
CN008: Loop signal weak Circuit signal is weak. • Check base station power supply.
• Check boundary circuit: the cable may be buried too
deep.
• Disconnect and then reconnect the transformer.
CN010: Bad position The robot has moved outside the
operating area.
• Return the robot to the operating area.
• Boundary cable crossover
CN011: Escaped robot The robot has moved outside the
operating area.
Check laying of the boundary cable (curves, obstacles,
etc.).
CN012: Cal: no loop
CN015: Cal: outside
Error during calibration: the robot has
not detected the circuit.
• Position the robot at right angles with respect to the
boundary cable; the robot must be able to straddle
the boundary cable.
• Check base station power supply.
• Check circuit.
• Disconnect and then reconnect the transformer.
• Boundary cable crossover.
CN018: Cal: Impact Error during calibration, impact Remove the obstacle.
CN038: Battery Battery discharged. • Check that there are no obstacles preventing the
robot from docking at the base station.
• Check the electrical charging contacts of the base
station.
• Circuit is too long or has too many islands.
• The robot lawnmower has become stuck.
Defective boundary cable, the
robot is unable to find the base
station.
Check the boundary cable for possible breaks, if
necessary have the circuit tested by an authorized
service centre
Spent battery. The battery has reached the end of its working life.
Contact an
authorized service centre to fit a new battery
Charging circuit electronics faulty. Contact an authorized service centre to replace the
charging circuit board
Robot does not connect with the
charging
contacts.
• Return the robot to the base station and ensure the
charging contacts are connected.
• Have the charging contacts checked and, if necessary,
replaced by an authorized service centre
