Help in case of malfunction
Fault code Cause Remedy
CN002: Lift sensor The lift sensor has triggered:
■
The appliance cover has
been deflected upwards
by lifting or by an
obstacle.
Remove the obstacle.
CN005: Bumper de-
flected
The appliance has driven
into an obstacle and cannot
free itself (e.g. collision close
to the base station).
■
Place the appliance on the free,
designated grass surface.
■
Correct the location of the boundary
cable.
CN007: No loop sig-
nal
■
No loop signal
■
The boundary cable is
faulty.
■
Loop signal is too weak.
■
Check the LEDs on the base sta-
tion.
■
Check the power source of the base
station. Disconnect and reconnect
the transformer.
■
Check the boundary cable for dam-
age. Repair the defective cable.
CN008: Loop signal
weak
■
Loop signal too weak
■
Boundary cable buried
too deep
■
Check the LEDs on the base sta-
tion.
■
Check the power source of the base
station. Disconnect and reconnect
the transformer.
■
Raise the boundary cable to the
prescribed height; attach directly on
the grass if necessary.
CN010: Bad position
■
The appliance is outside
the designated grass
surface.
■
The boundary cable has
been routed in a criss-
cross pattern.
■
Place the appliance on the free,
designated grass surface.
■
Correct the location of the boundary
cable around curves and obstacles.
Eliminate the criss-crossing of the
cable.
CN011: Escaped robot The appliance is outside the
designated grass surface.
Correct the location of the boundary
cable around curves and obstacles.
CN012: Cal: no loop
CN015: Cal: outside
Fault during the calibration:
■
The appliance cannot
find the boundary cable.
■
Check the LEDs on the base sta-
tion.
■
Check the power source of the base
station. Disconnect and reconnect
the transformer.
■
Place the appliance at the pre-
scribed calibrating position; align
precisely at right angles. The appli-
ance must be able to drive over the
boundary cable.
