Signal quality should always be 100% for satisfactory
function The signal from the boundary loop is designated
the A signal. See the illustration below for examples of
high and low signal strengths.
The strength of the A signal also varies along the
boundary loop depending on the proximity to other parts
of the loop. The strength of the signal is affected by the
size of the working area, islands, headlands, passages
and corners. The signal can also be affected by magnetic
objects in the ground or in nearby walls and buildings.
The signal is weakened in these areas. Examples
of magnetic objects are iron fences, iron girders and
reinforcement bars. Grass areas laid on concrete roofs
can therefore receive a weakened signal.
When the signal is reinforced or weakened, it is normal
that both low and high signal strengths are not always
available along the entire boundary loop.
The loop signal’s reception and amplification in the mower
can also vary by +/- 10% from one mower to another.
This means that at the same point in an installation,
one mower can display A=90 and another one A=100.
The charging station’s circuit board and the mower’s loop
sensor can also give certain variations between different
machines.
See
2.2.1 Info
for more information on how the loop signal
can be read in the mower’s display.
