6. TROUBLE SHOOTING
6.2.3 Fault symptoms with“Follow loop”
6.2.4 Fault symptoms during Docking
Automower
®
does not run
along the guide wire when
it searches for the
charging station.
Automower
®
is set to
follow the guide wire on
the left-hand side in the
direction towards the
charging station.
Automower
®
does not find the strength
on the loop signal that the set corridor
width corresponds to.
If the boundary wire to the left of the guide wire, seen
in the direction towards the charging station, and the
guide wire are routed close together; reduce the
corridor width until the Automower
®
manages to
follow the guide wire. Use the function Test IN, see
3.4 Testing the installation on page 50.
Increase the distance between the boundary wire to
the left of the guide wire, seen in the direction
towards the charging station, and the guide wire. The
distance between the boundary wire and the guide
wire should be at least 30 cm (12”).
Symptom
(follow loop)
Cause Action
Automower
®
follows the
boundary wire in a saw
tooth pattern
Automower
®
does not find the strength
on the loop signal that the set corridor
width corresponds to. Automower
®
now
searches for the strength by running in a
saw tooth pattern along the boundary
wire.
Increase the corridor width until the behaviour stops.
Automower
®
can not pass
through a narrow opening
or passage when
following the boundary
wire.
The corridor width is too high for
Automower
®
to pass through the
passage.
Reduce the corridor width successively until
Automower
®
can pass through the passage. In order
to prevent Automower
®
from running on a small
corridor width, install a guide wire through the
passage. Use the function Test IN, see
3.4
Testing the installation on page 50.
Automower
®
does not
follow the boundary wire
out from the charging
station to a remote area
when it should, but starts
mowing directly.
Automower
®
does not find the strength
on the loop signal that the set corridor
width corresponds to. When
Automower
®
does not detect the strength
after reversing out of the charging
station it starts to mow instead.
Try a different corridor width, a greater corridor width
usually improves the function. Check the loop signal
strength and compare with Table 8 and Table 9. Also
try to adjust the mower's reversing distance.
Automower
®
does not
follow the guide wire out
from the charging station
to a remote area when it
should, but starts mowing
directly.
Automower
®
does not find the strength
on the loop signal that the set corridor
width corresponds to. When the mower
reverses out from the charging station it
turns a full circle to find the strength.
When Automower
®
does not find the
strength it starts to mow instead.
Check that the guide wire has been routed correctly.
It should be routed at least 130 cm (52”) straight
back, out from the edge of the charging station. The
adjustable reversing length must be adapted
according.
Try a different corridor width, a greater corridor width
usually improves the function. Check the loop signal
strength and compare with Table 8 and Table 9.
Symptom (docking) Cause Action
Automower
®
detects the
signals from the charging
station but is not able to
dock successfully
The charging plate (N-coil) is defective. Check the N-signal from the charging station: Place
the Automower
®
in the test position and then check
the value via the Quick check function (Press and
hold the 0 key down for 2 seconds). The N-coil is
defective if the value for N is lower than 100. The
charging plate must be replaced.
