The robotic lawnmower has an inbuilt standby
period according to the Standby time table.

6.5 Find breaks in the loop wire
Breaks in the loop wire are usually the result of
unintentional physical damage to the wire such as when
gardening with a shovel. In countries with ground frost,
also sharp stones that move in the ground can damage
the wire. Breaks can also be due to the wire being
stretched excessively during installation.
Mowing the grass too low right after the installation can
damage wire insulation. Damage to the insulation may
not cause disruptions until several weeks or months
later. To avoid this, always select the maximum cutting
height the first weeks after installation and then lower
the height one step at a time every second week until
the desired cutting height has been reached.
A defective splicing of the loop wire can also lead to
disruptions several weeks after the splice was done. A
faulty splice can, for example, be the result of the
original coupler not being pressed together hard enough
with a pair of pliers, or that a coupler of lower quality
than the original coupler has been used. Please first
check all known splices before further troubleshooting is
done.
A wire break can be located by gradually halving the
distance of the loop where the break may have occurred
until there is only a very short section of the wire left.
The following method does not work if
ECO mode is
activated. Make sure first that
ECO mode is turned off.

ECO mode on page 23.
1. Check that the indicator lamp in the charging station
flashes blue, which indicates a break in the
boundary loop. See
Indicator lamp in the charging
2. Check that the boundary wire connections to the
charging station are properly connected and not
damaged. Check that the indicator lamp in the
charging station is still flashing blue.
POWER R L GUIDE
3. Switch the connections between the guide wire and
the boundary wire in the charging station.
Start by switching connection L and GUIDE.
If the indicator lamp is lit with a solid green light,
then the break is somewhere on the boundary wire
between L and the point where the guide wire is
connected to the boundary wire (thick black line in
the illustration).
Guide
To rectify the fault you will need boundary wire,
connector(s) and coupler(s):
a) If the suspected boundary wire is short then it is
easiest to exchange all of the boundary wire
between L and the point where the guide wire is
connected to the boundary wire (thick black line).
