Loop Signal Strength - Husqvarna Automower 210 C Technical Manual

6.3 Loop signal strength

Below are the loop signal strength levels for the
respective Corridor width. The strength that the
Automower ® follows varies from search to search. For
example, with Corridor width 6 set on the 02.71
260ACX (2010) mower program, the signal strengths
for the boundary loop varies between 255-286
The low strength is the one that the mower searches
for when it follows the boundary wire at maximum
distance. The higher strength is the one that the
mower searches for when it follows the loop at the
minimum distance.
When Automower is set to follow the boundary wire or
®
the guide wire with the help of the Test IN function
(3-2-4), it follows the loop according to the low strength
on the loop signal, that is to say, at maximum distance
from the loop. Consequently, you should always use
the Test IN (3-2-4) function when testing whether the
set corridor width is appropriate.
