6. TROUBLE SHOOTING
No loop signal Break in the boundary wire or no voltage
to the charging station.
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
5.23
Checking the loop on page 101 for more
information.
The transformer is not connected to the
mains supply or its miniature
circuit-breaker has tripped.
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.
Communication between the Automower
®
and the charging station has broken
down.
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.
The boundary wire has been routed the
wrong way around an island.
Check that the boundary wire has been routed in
accordance with the installation instructions.
The circuit card in the charging station is
defective.
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.
The front loop sensor card is defective. 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.
The control box in the mower is defective. 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% and
the circuit card in the charging station is in working
order, the control box is defective and must be
replaced.
If this occurs in isolated areas it may be
due to interference from metallic objects
(perimeter fence, reinforcement bar) or
buried cables in the vicinity.
Try moving the boundary wire.
Front loop sensor defect 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%, the cabling to the front loop sensor
is defective or has come loose.
The front loop sensor card is defective. 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.
Rear loop sensor defect The cabling to the rear 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. 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.
