6.6 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 occur 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.
