Possible cause
Cover has been deflected
upwards by lifting or by a
foreign body.
Robotic lawn mower has en-
countered an obstacle and
cannot free itself (collision
close to base station).
No loop signal.
Fault during calibration, loop
signal too weak.
Loop signal weak.
Robotic lawn mower is outs-
ide loop.
Robotic lawn mower has left
field.
Fault during calibration, ro-
botic lawn mower could not
find loop.
Fault during calibration, colli-
sion
Battery flat.
Boundary cable defective,
robotic lawn mower does not
find base station.
Battery exhausted.
Charging electronics faulty.
Solution
Remove foreign body.
Check base station power supply
Check loop
Disconnect and reconnect transformer
Check base station power supply
Check loop, it has possibly been buried too
deep
Disconnect and reconnect transformer
Place robotic lawn mower in mowing area
Loop crossed-over
Check routing of loop (curves, obstacles, etc.)
Place robotic lawn mower at right angles to
loop, robotic lawn mower must be able to drive
over loop
Check base station power supply
Check loop
Disconnect and reconnect transformer
Loop cable crossed-over
Remove obstacle
Check base station for obstacles
Check base station charging contacts
Loop too long, too many islands
Robotic lawn mower has got stuck
Check boundary cable for interruptions, if ne-
cessary have it tested by a service partner.
Battery service life exceeded. Have battery rene-
wed by a service partner.
Have charging electronics renewed by a service
partner.
