Finding Breaks In The Loop Wire - Husqvarna Automower 320 Operator's Manual

9.5 Finding 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. Certain 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 first 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.
See 6.9 Settings on page 59.
1. Check that the indicator lamp in the charging
station flashes blue, which indicates a break in
the boundary loop. See 9.3 Indicator lamp in the
charging station on page 79.
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.
