Break in the boundary wire or no voltage
to the charging station.
The transformer is not connected to the
mains supply or its miniature
circuit-breaker has tripped.
Communication between the Automower
and the charging station has broken
down.
The boundary wire has been routed the
wrong way around an island.
The circuit card in the charging station is
defective.
The front loop sensor card is defective.
The control box in the mower is defective. Check the levels for Af and Ar via Quick check (Press
If this occurs in isolated areas it may be

(perimeter fence, reinforcement bar) or
buried cables in the vicinity.
The cabling to the front loop sensor is
defective or has come loose.
The front loop sensor card is defective.
The cabling to the rear loop sensor is
defective or has come loose.
Action
First check that the LED on the charging station is
solid or flashing. This indicates that there is power to
the charging station. If it is flashing once per second,
the loop is damaged. Repair the breakon the cable
using the original water-tight connector. See
Checking the loop
on page 101 for more
information.
Check the wall socket connection and whether the
miniature circuit-breaker has tripped.
Reset the miniature circuit-breaker by removing the
transformer's power cord from the wall socket, wait
10 seconds and then reconnect the power cord in the
wall socket again.
Place the Automower in the charging station and
® ®
state the PIN-code again via Settings- Security - PIN
code (shortcut 4-1-1). You can use the same PIN
code as earlier.
Check that the boundary wire has been routed in
accordance with the installation instructions.
Check the levels for Af and Ar via Quick check (Press
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. When both Af
and Ar are 0 or when Quality is lower than 100%, the
circuit card in the charging station is defective and
must be replaced.
Check the levels for Af and Ar via Quick check (Press
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. When Af is 0
and Ar is higher than 70 (the mower is outside the
charging plate, but inside the loop) or when Quality is
lower than 100%, the front loop sensor card is
defective and must be replaced.
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. When both Af
and Ar are 0 or when Quality is lower than 100% and
the circuit card in the charging station is in working
order, the control box is defective and must be
replaced.
Try moving the boundary wire.
Check the levels for Af and Ar via Quick check (Press
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. When Af is 0
and Ar is higher than 70 (the mower is outside the
charging plate, but inside the loop) or when Quality is
lower than 100%, the cabling to the front loop sensor
is defective or has come loose.
Check the levels for Af and Ar via Quick check (Press
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. When Af is 0
and Ar is higher than 70 (the mower is outside the
charging plate, but inside the loop) or when Quality is
lower than 100% and the cabling to the front loop
sensor is undamaged, it is the front loop sensor card
that is defective and must be replaced.
Check the levels for Af and Ar via Quick check (Press
and hold the number 0 down for 2 seconds). Switch
between Af and Ar with the YES button. Switch
between Af and Ar with the help of Arrow up. When
Ar is 0 and Af is higher than 70 (the mower is outside
the charging plate, but inside the loop) or when
Quality is lower than 100%, the cabling to the rear
loop sensor is defective or has come loose.
