Find Breaks In The Loop Wire - Husqvarna AUTOMOWER 305 Operator's Manual

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.
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
mode is activated. Make sure first that ECO
mode is switched off. Refer to ECO mode on
page 31 .
1. Check that the indicator lamp in the charging
station flashes blue, which indicates a break
in the boundary loop. Refer to
in the charging station on page 48 .
2. Check that the boundary wire connections to
the charging station are properly connected
and not damaged. Check that the indicator
1462 - 001 - 24.02.2020
lamp in the charging station is still flashing
blue.
3. Switch the connections between the guide
wire and the boundary wire in the charging
station.
Start by switching connection and .
If the indicator lamp has a solid green light,
then the break is somewhere on the
boundary wire between and the point where
the guide wire is connected to the boundary
wire (thick black line in the illustration).

To rectify the fault you will need boundary
wire, connector(s) and coupler(s):
Indicator lamp
a) If the suspected boundary wire is short
then it is easiest to exchange all of the
boundary wire between and the point where
the guide wire is connected to the boundary
wire (thick black line).
b) If the suspected boundary wire is long
(thick black line) then do as follows: Put and
back to their original positions. Then
disconnect . Connect a new loop wire to .
Connect the other end of this new loop wire
at the middle of the suspected wire section.
