The Loop System's Control Signals - Husqvarna Automower Solar Hybrid Technical Manual

each night it will never, in principle, perform
square mode cutting.
3. The instantaneous power consumption to
maintain the speed of the blade disc must deviate
from the average power by the set factor (e.g.
50 %). Consequently, the lawn in one area must
always be longer/thicker than before.
When an Automower seems to perform square mode
cutting too often:
• The lawn in the working area is cut very short.
This means the average power is set very low and
the Automower will then start square mode cutting
more often/easier.
When an Automower rarely seems to perform square
mode cutting:
• The mower has been turned off using the main
switch for more than 4 hours, which has reset the
time counter.
• An object has wound itself around the skid plate or
the blade disc, which means the power
consumption has increased, and the Automower
then interprets this as the grass being
longer/thicker than before.
1.9 The loop system's control
signals
The loop system, consisting of the boundary wire
connected to the charging station, basically
comprises five different signals A-signal, F-signal,
N-signal, Guide 1 and Guide 2.
See Loop (5-2-4), page 37 to check the F and
N-signals.
A-signal =
The signal that the charging station transmits over the
loop and which demarcates the working area for the
Automower. Coded information is transmitted via the
A-signal to the mower. This is unique for each
individual installation.
When there is no A-signal, for example with a break
in the boundary wire or in the power supply to the
charging station, the Automower stops and displays
the fault message No loop signal.
When the LED on the charging station (loop
generator/charger for 210 C) is lit with a steady light
this indicates that there is power and that the boundary
wire is intact. See the table on page 14 for other
indications.
