4. AUTOCHECK, SERVICE PROGRAM
The following values are stated for the A-signal and
Guide signals:
• Af = The strength of the A-signal measured via
the front loop sensor on the mower. The value
should lie between approximately 70 and 320 to
ensure good functionality. The closer to the loop
the mower is, the higher the value. When the
Automower is directly over the loop the value is 0
and when the mower is outside of the loop the
value is negative.
• Ar = The strength of the A-signal measured via
the rear loop sensor on the mower. The guideline
values of approximately 70 – 320 also apply for
Ar.
• Guide 1 and Guide 2 = The strength of each
guide signal 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. To ensure the
functionality of the guide wire, the Guide signal
value should be (-) 250 – 320 next to the guide
wire.
In order to obtain usable values from the F- and
N-signals the Automower must be in the test position.
This means the nose of the mower is partly edge to
edge with the charging station base plate, partly to the
right of centre. See the picture opposite. Tick the
Mower is standing in test position checkbox when you
have positioned the mower correctly.
The value of the F-signal should be more than 300
and for the N-signal the value should be over 100.
The value stated for Quality, is a measurement of the
loop system's total function. When a value other than
100 % is stated, this indicates that the system is
malfunctioning and the values shown for loop signals
are not correct.
On 210 C only Quality and the A-signal are available.

Loop system reminder:
A-signal: Signal that the charging station transmits
to the loop and which the loop sensors then
interpret. 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.
