Corridor Width - Husqvarna Automower Technical Manual

1. Function
The strength of the signal in the guide loop is
dependent on the length of the loop. Consequently, the
guide loop should be as short as possible, preferably
no longer than about 200 metres. See the picture
below for examples of guide wire installation.
Example 1:
Installation of the guide
wire = Approved
Guide loop < 200 m
The longer the guide loop the lower the signal strength
and the harder it is for the Automower to follow the
guide wire. A lower signal strength means that the
mower, with a given corridor width, will be run closer to
the guide wire. Should the strength of the signal
become too low, the Automower may, for example in a
closed corner, stop following the guide wire.
The strength of the S-signal also varies along the guide
loop depending on the proximity to other parts of the
guide loop and is affected by islands, heads, passages
and corners.

1.9 Corridor width

The corridor width determines the maximum distance
from the boundary wire or the guide wire that the
Automower is permitted to run when it follows the
loop or the wire on route to or from the charging
station. A low corridor width value represents a
narrow corridor while a high value represents a wide
corridor.
With a narrow corridor the Automower always runs
close to the boundary wire respective guide wire.
With a wide corridor the Automower varies how it
runs, i.e. close to and further from the boundary wire
respective guide wire. A wide corridor reduces the
risk of tracks forming.
