6. TROUBLE SHOOTING
Cause
Automower will not pass through narrow
passages.
The position of the charging station is
unsuitable.
The charging plate (F-coil) is defective.
Poor contact between the Automower and
the charging station.
The battery is spent or defective.
Wrong PIN code has been entered. Three
attempts are permitted, the keypad is
then blocked for five minutes. However,
the function Discover PIN code works,
this is accessed by pressing and holding
down the 9 key for 5 seconds.
The Automower has become caught in
something.
The lift sensor has been activated as the
mower has become trapped.
The lift sensor card is defective.
Pillar or magnet fitted incorrectly
An object prevents the Automower from
rolling out of the charging station.
The contact strips jams.
Action
Check all passages in the working area by positioning
the mower beyond the passage, seen in the direction
from the charging station, and press Home. If the
mower does not pass through the passage, change
the Corridor width setting via Garden - Follow loop -
Corridor width (shortcut 3-2-3).
Check that the charging station has been placed as
set out in the installation instructions.
Check the F-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 F-coil is defective if
the value for F is lower than 300. The charging plate
must be replaced.
Check the charging current 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). Contact is
poor if the current (I) is lower than 3,0A (1.6A for 220
AC). Now check the contact strips on the charging
station and charging strips and charging cabling on
the mower.
When the running time on the mower exceeds
3000 hours the battery is spent.
When the mower is locked: Wait 5 minutes until you
can enter the code again. Now enter the correct PIN
code.
Free the mower and rectify the reason for the lack of
drive.
Free the Automower and rectify the reason for it
getting trapped.
Check the lift sensor via Tools - Test - Sensors
(shortcut 5-2-5). When the mower has been lifted, i.e.
when the lift sensor is activated, the mower should
indicate YES on the display.
Check that the pillar and magnet have been fitted
correctly. The magnet must be fitted on the right-hand
pillar. Two dashes on the chassis mark where the
magnet should be seated. Make sure that the body
can move freely up and down in relation to the
chassis.
Remove the object.
Check that the contact strips on the charging station
are not jammed. Round off the charging strips on the
Automower if necessary using emery cloth and
lubricate with copper paste.
