Husqvarna Automower Solar Hybrid Technical Manual page 38

Ar = The strength of the A-signal measured via the
rear loop sensor on the mower. Ar is shown when
you press Arrow up. The guideline values of
approximately 70 – 320 also apply for Ar.
• S, G1 and G2 = The strength of the guide signal
for each guide wire measured via the front loop
sensor and close to the guide wire. To the left of
the guide wire, in the direction towards the
charging station, the value is negative and to the
right of the wire the value is positive. The guide
wire is named G1 for 220 AC and the guide wires
are named G1 and G2 for 230 ACX and Solar
Hybrid. To ensure the functionality of the guide
wire, the value should be (-) 250 – 320 next to the
guide wire.
• F = an indication of the F-signal strength. The
F-signal is generated by the large coil in the
charging station plate.
• N = an indication of the N-signal strength. The
N-signal is generated by the two small coils in the
charging station plate.
• Quality = an indication of the loop's overall
function. The normal value is 100 %. Another
value indicates there is a system malfunction.
• Restarts = an indication that the loop system is
restarting. Within 5 – 10 seconds after the function
starts, the restart value stabilises. When the value
continues to change this indicates that the system
is affected by interference or is defective.
The value for Ar is shown when you press Arrow up.
When the rear loop sensor is malfunctioning the Ar
value is constant and the Quality value is 0 %.

2. SPECIAL MENU FUNCTIONS
Loop system reminder:
The charging station generates four signals, one to
the boundary wire, one to the guide loop and two to
the coils in the plate.
A-signal: Signal that demarcates the working area.
Normal value for the A-signal: about 70 – 320.
Guide signal: Signal that delimits the guide area.
Default value for the Guide signal next to the guide
wire: about (-) 250 – 320.
F-signal: Remote signal that helps the Automower
to find the charging station. Normal value for F with
Automower in the test position: Over 300.
N-signal: Near signal that guides the Automower
into the charging station. Normal value for N with
Automower in the test position: Over 100.
The loop signals can only be interpreted if the
Quality value is 100 %. When the value is 99 % or
lower, the loop system does not function correctly
and with that, the displayed values for the signals
will not be correct.
