3.3.2 Sensors

The appliance is provided with
several safety sensors. It does
not restart automatically after be-
ing switched off by a safety sen-
sor. The error message is shown
on the display and must be ac-
knowledged. The reason for the
triggering of the sensor must be
resolved.
Lifting sensor
If the appliance is raised by the
housing during operation, the
travel drive switches off and the
cutting blades are stopped.
Bump sensors for obstacle
detection
The appliance is equipped with
sensors that ensure it changes
its direction of travel if it encoun-
ters obstacles. When it encoun-
ters an obstacle, the top part of
the deck is shifted slightly and
the shock sensor triggered.
44
Tilt sensor in direction of
travel/sideways
If an upward or downward slope
or a laterally inclined angle of
24° (45 %) is reached in the di-
rection of travel, the appliance is
turned or the appliance changes
its direction of travel.
Rain sensor
The appliance is equipped with a
rain sensor that (when activated)
interrupts the mowing procedure
in case of rain, and ensures that
the appliance returns to the
charging station.
NOTE
The appliance can be op-
erated reliably in the im-
mediate vicinity of other
automatic lawnmowers.
The signal used in the
boundary cable corre-
sponds to the standard de-
fined by the European
Garden Machinery Indus-
try Federation (EGMF)
with regard to electromag-
netic emissions.
