are automatically combined to find the charging station
as quickly as possible but also with a minimum risk of
tracks forming.
In very complex gardens e.g. with many areas joined by
narrow passages, the amount of time required to find the
charging station is decreased by carrying out a number
of the manual settings outlined below.
The robotic lawnmower always starts the search for the
charging station using an irregular search method.
When the robotic lawnmower still cannot find the
charging station after a specific period of irregular
searching, it also starts to search for the guide wires and
after a further period also the boundary wire to follow
one of them into the charging station instead. This time
is specified in minutes and is known as delay time.
Example:
3 minute delay for Guide and 11 minutes for the
boundary loop. The robotic lawnmower then searches
irregularly for 3 minutes and then searches for the guide
wires for 8 minutes. If it has not found a guide wire after
this period, the robotic lawnmower now also searches
for the boundary loop.
It is possible of course to specify the same delay time for
both the guide wires and boundary loop, for instance 5
minutes. The robotic lawnmower then searches
irregularly for 5 minutes and when it does not find the
charging station, it continues to search either by
following the guide wires or the boundary loop,
depending on which one it reaches first.
In general a long delay time decreases the risk of tracks
forming (the robotic lawnmower will find the charging
station more often through irregular searches) but gives
longer search times. A short delay time gives the
opposite effect, i.e. short search times with increased
risk of tracks forming along the guide wires and/or
boundary wires.
3.17.4.1 Overview
This overview summarises the selected settings for each
search method. To edit the settings for a method, select
the method using left and right arrow keys followed by
OK.
3.17.4.2 Guide
Move the cursor to suitable guide wire.
Use the number keys to enter the delay time.
The delay time is normally specified as a figure between
0 and 10 minutes.
30 - Installation
3.17.4.3 Guide > Disable / Enable
Normally the Guide method does not need to be
deactivated even if there is no guide wire installed.
However, to disable the Guide method, select
and press OK.
3.17.4.4 Boundary loop
Use the number keys to enter the delay time.
This time is normally longer than for
normally better if the robotic lawnmower follows the
guide wire home to the charging station. The delay time
is normally specified as a figure between 10 and 20
minutes but can be shorter if the guide wire is not
installed and it is unlikely that the robotic lawnmower
can find the charging station through an irregular search.
If the robotic lawnmower passes a guide wire while
following the boundary wire, it will stop searching along
the boundary wire and instead start to follow the guide
wire into the charging station.
3.17.4.5 Boundary loop > Disable / Enable
If it is very inappropriate in the installation to follow the
boundary loop, the Boundary method checkbox has to
be deactivated. To disable the boundary method, select
Disable and press OK.
3.17.4.6 Boundary > More > Test right / Test left
Testing selected settings can be seen as a natural part
of the installation.
1. Place the robotic lawnmower about 3 m / 10 ft. from
the boundary wire, facing the wire.
2. The test function is found in
charging station > Boundary .
More and press OK.
3. Select
Test right/Test left , and press OK.
4. Select
5. Press START and close the hatch.
6. Check that the robotic lawnmower follows the guide
wire all the way to the charging station and that it
docks with the charging station. The test is approved
only if the robotic lawnmower is able to follow the
guide wire the entire distance to the charging station
and docks at the first attempt. If the robotic
lawnmower is unable to dock on the first attempt, it
will automatically try again. The installation is not
