Husqvarna Automower Solar Hybrid Technical Manual page 14

F-signal (only 220 AC, 230 ACX and Solar Hybrid) =
Remote signal from the charging station which has a
range of 6 – 7 metres. The signal is generated by the
large coil in the charging station plate. The F-signal
guides the mower in the direction of the charging
station.
When there is no F-signal, the Automower will not be
able to find the charging station. The mower will
eventually stop and display the fault message Low
battery voltage.
N-signal (only 220 AC, 230 ACX and Solar Hybrid) =
Near signal from the charging station with a range of
approximately 1 metre. The signal is generated by the
two small coils in the charging station plate. The
N-signal guides the Automower directly into the
charging station, so that the charging strips and
contact strips make contact.
The Automower cannot enter the charging station
when there is no N-signal. The mower will eventually
stop and display the fault message Low battery
voltage
Guide 1 and Guide 2 (only 220 AC, 230 ACX and Solar
Hybrid) =
Signal that the charging station transmits out through
the guide wires. The Guide 1 and Guide 2-signals lead
the mower along each Guide wire to or from a remote
area. Guide 1 and Guide 2 are marked at the rear of
the charging station. Guide 2 is only available for
230 ACX and Solar Hybrid.
Automower can not follow the guide wire if there is no
Guide-signal.

Cause
The boundary wire is broken or the circuit card in the
charging station is defective. See page 87 to replace the
card. Test short-circuiting the terminal pin with a short
conductor.
Too high loop resistance. This may be on account of the
boundary wire being too long or that the cable is damaged.
If the mower works, it is not a problem.
Defective coil in the charging station plate or a defective
circuit card. See page 87 to replace the plate. See page 87
to replace the card.
