1m²). If the robot lawn mower comes up against a
boundary of the mowing area, it can use various
parameters to determine a boundary quality value.
5.9.1 Initialization run – getting started
Make sure that the robot lawn mower's battery is
fully charged at the beginning of the initialization
run. Then the robot lawn mower can complete the
defi nition of a reference value in one operation. If
one battery charge is not enough for the initializa-
tion run, the robot lawn mower will automatically
return to the charging station (19) and continue its
run after charging.
For the reliability of the mowing area boundaries
to be determined, an individual reference value
per mowing area must be created for the robot
lawn mower's operation.
To determine the reference value the robot lawn
mower moves as usual in a random direction
within the mowing area. If the robot lawn mower
comes up against a boundary or an obstacle, it
will stop and evaluate the mowing area ahead of
it. Then the robot lawn mower will start moving
again in a random direction. For safety reasons
the initialization run takes place with the mo-
wer unit switched off .
If the robot lawn mower comes up against a
boundary of the mowing area, this boundary will
be evaluated and the guide cable LED (56) will
light up. Green signals a reliable boundary of the
mowing area and yellow an unreliable boundary.
The robot lawn mower indicates the quality of a
lawn boundary both in the initialization run and
during automatic mode.
For reliable determination of the reference value
you need at least 200 contacts with a boundary
of the mowing area. The boundary quality value
is checked for its reliability after more than 200
contacts. If the robot lawn mower decides that the
value is not yet reliable enough, it will continue its
initialization run for a further 200 contacts.
If the initialization run was successful so that it
was possible to create a reliable boundary quality
value, the robot lawn mower will begin to mow the
mowing area in accordance with its mowing time
setting.
If there was no success in creating a reliable re-
ference value, the robot lawn mower will stop and
the guide cable LED (56) will fl ash red. Check the
boundaries of the mowing area and correct the
boundaries which do not diff er clearly from the
mowing area. Make sure that the mowing area dif-
fers clearly from the surrounding area. Now delete
the existing reference value (see 5.9.4) and then
repeat the initialization.

5.9.2 Checking the boundary's quality in ope-
ration
When the robot lawn mower is in automatic mode,
it checks in regular intervals whether the current
boundary quality value of the mowing area has
changed compared to its reference value. As soon
as the robot lawn mower is in the charging station
(19), the corresponding status of the last deter-
mined comparative boundary quality value will be
displayed via the guide cable LED (56). This value
is compared at the same time with the reference
value determined during the initialization run.
The guide cable (56) lights up green:
The robot lawn mower is situated in the charging
station (19) or near the search loop and the devia-
tion from the reference quality value is small.
The guide cable (56) fl ashes yellow:
The robot lawn mower is situated in the charging
station (19) or within the search loop and the
deviation from the reference quality value has
worsened.
The guide cable LED (56) fl ashes red:
The robot lawn mower is situated in the charging
station (19) or inside the search loop and the
deviation from the reference quality value is too
big. The robot lawn mower stays in the charging
station (19). Check the boundaries of the mowing
area. Then delete the reference value (see 5.9.4)
and carry out a new initialization of the boundary
quality value.
The guide cable LED (56) is OFF:
•
The guide cable (24) is not connected cor-
rectly or has been damaged.
•
The power supply to the charging station (19)
has been interrupted.
•
The robot lawn mower is situated outside the
search loop.
5.9.3 Operating the robot lawn mower in se-
condary areas
The robot lawn mower can create an individual
value for the main area and the secondary area.
This means that you must carry out an initiali-
zation run in each new secondary area. You are
only allowed to use the robot lawn mower on one
secondary area. If you want to mow with the robot
lawn mower on an additional secondary area it is
absolutely essential to delete the boundary quality
value of the secondary area and to carry out an
initialization run.
