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.
