Husqvarna Automower 320 Technical Manual page 15

The Automower always starts a search for the charging
®
station using the Irregular method, on the condition
that the delay times for the boundary wire or any of the
guide wires are not set to 0 minutes.
Irregular searching means that the Automower
in an irregular pattern until it encounters the F field by
the charging station. The strength of the F signal which
is required for the mower to react is set in the Charging
station range setting.
If a guide wire is installed and the delay time for this
wire has elapsed, the Automower
for and follow it to the charging station. If the delay
time for the boundary loop also elapses before the
Automower has found the charging station, the mower
®
will also start searching for the boundary loop. If the
mower then finds and follows the boundary loop, it
keeps going until it has found the charging station or
crosses the guide wire. If it crosses the guide wire, the
robotic lawnmower will follow it instead to the charging
station.
When the mower follows the boundary loop or a guide
wire, it travels a distance into the F field before the F
and N signals direct it correctly into the charging station.
If the boundary loop is laid around an island, the
Automower follows the loop twice around the island
®
before it leaves it and travels on to encounter the
boundary loop at another point.
If the Automower encounters an obstacle while
®
following the boundary loop, it passes it by travelling
in one or more loops around the obstacle.
If the robotic lawnmower encounters an obstacle when
it follows a guide wire, it passes it by running closer
to the guide wire.
