For more information about The loop system, see 1.8
Loop signal strength on page 12 and 1.9 Corridor
width on page 14.
The clock in the
Automower shows
strange times.
The battery in the control box is
defective.
Replace the battery, see page 112 about
replacement.
The control box is defective. Replace the control box, see page 108 about
replacement.
The background lighting
on the display is on, but
the keypad and main
switch do not react.
The control box is blocked. 1. Reprogram the control box with the help of
Autocheck. Use the Advanced function and
download the program manually. Ignore the
Autocheck message No contact.
2. Should the program not start or it is cancelled
before it is finished, the battery may need to be
charged for a few minutes. However, do not charge it
for more than 10
minutes as the charging/battery's
temperature can not be monitored when the control
box is blocked.
3. Also refer to page 83.
Table 13: Fault symptom, Loop system
Symptom, Loop
system
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.
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.
When the working area is large/open and when the
distance between the boundary wire is large, choose
a wider corridor. When the working area is
small/narrow and the distance between the boundary
wire is small, choose a narrower corridor.
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 130cm straight back, out
from the edge of the charging station. The adjustable
reversing length must be adapted according.
