1.8 The loop system’s control
signals
The loop system consists of a boundary wire and
a guide wire connected to the charging station.
Together they essentially comprise three different
signals:
• A signal
• F signal
• Guide signal
To check the A, F and Guide signals, see
“Loop (5-1-3)” .
• A signal
The signal that the charging station transmits
over the loop and which demarcates the
working area for the robotic lawnmower.
Coded information is transmitted via the
A signal to the mower.
If there is no A signal, for example due to a
break in the boundary wire or in the power
supply to the charging station, the robotic
lawnmower stops and displays the No loop
signal message.
• F signal
Remote signal from the charging station
which has a range of 2-3 metres. The signal
is generated by the large coil in the charging
station plate. The F signal is used so that the
mower knows that it is in the vicinity of the
charging station.
If there is no F signal, the robotic lawnmower
will not be able to find the charging station.
The mower will eventually stop and display
the message “Low battery voltage” .
• Guide signal
The signal that the charging station transmits
through the guide wire. The guide signals
lead the mower to the charging station,
but can also be used to direct the mower
to a remote area. Guide is marked at the
connection on the rear of the charging
station.
If there is no Guide signal, the robotic
lawnmower cannot follow the guide wire and
will therefore not be able to find the charging
station. The mower will eventually stop and
display the Low battery voltage message.
1.9 The loop system’s status
The loop system’s status is most easily checked
using the LED in the charging station. Check the loop
signal by inspecting the LED indicators.
• Solid green light = All signals are OK.
• Green flashing light = The A signal has been
turned off in the boundary wire (ECO mode).
• Blue flashing light = No signal in the
boundary wire (A signal). Most likely a break
in the boundary wire.
• Yellow flashing light = No signal in the guide
wire. Most likely a break in the guide wire.
• Red flashing light = No F signal. Most likely
interruption in the charging station’s antenna
plate
• Solid blue light = Weak signal in the
boundary wire (A signal). This may depend
on the boundary wire being over 250 m in
length or that the wire is damaged. If the
mower still works, this is not a problem.
• Solid red light = fault in a circuit board in the
charging station.
