Automower from 119
6. Trouble shooting
™
No loop signal Boundary wire broken. Check the signal given by the LED on the charging
station. If it flashes the loop is damaged. Repair the
broken cable using an original waterproof coupler.
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.
The connection between the Automower
and the charging station has been lost.
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 Tools - Test -Loop
(shortcut 5-2-4). Switch between Af and Ar with the
help of Arrow up. 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 Tools - Test -Loop
(shortcut 5-2-4). Switch between Af and Ar with the
help of Arrow up. 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 Tools -Test -Loop
(shortcut 5-2-4). Switch between Af and Ar with the
help of Arrow up. 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 Tools -Test -Loop
(shortcut 5-2-4). Switch between Af and Ar with the
help of Arrow up. 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 Tools - Test -Loop
(shortcut 5-2-4). Switch between Af and Ar with the
help of Arrow up. 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.
