1. FUNCTION
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.
1.7 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 (for 210 C only the
A-signal applies).
See
Loop (5-’2-4), page 38
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.
