Cause
The lift sensor has triggered:
■
The appliance cover has
been deflected upwards
by lifting or by an
obstacle.
The appliance has driven
into an obstacle and cannot
free itself (e.g. collision close
to the base station).
■
No loop signal
■
The boundary cable is
faulty.
■
Loop signal is too weak.
■
Loop signal too weak
■
Boundary cable buried
too deep
■
The appliance is outside
the designated grass
surface.
■
The boundary cable has
been routed in a criss-
cross pattern.
designated grass surface.
Fault during the calibration:
■
The appliance cannot
find the boundary cable.
Remedy
Remove the obstacle.
■
Place the appliance on the free,
designated grass surface.
■
Correct the location of the boundary
cable.
■
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.
■
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.
■
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.
Correct the location of the boundary
cable around curves and obstacles.
■
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.
