6. TROUBLE SHOOTING
Cause
The set delay time does not permit
Automower to start following the guide
wire when it searches for the charging
station.
Automower does not find the strength on
the loop signal that the set corridor width
corresponds to.
Cause of fault message
Automower has collided with an obstacle
in the N-field.
The charging plate (N-coil) is defective.
The contact between the charging strips
and contact strips is poor and the
Automower has made a number of
charging attempts.
Action
Check that the set delay time to permit Automower to
start following the guide wire has elapsed. To easily
check that Automower starts to follow the guide wire,
the delay time can be set to 0 minutes.
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.
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").
Action/Check
Is anything blocking the N-field?
The charging station may need to be moved.
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.
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. Also test the charging current with the
help of the Quick check function (press and hold the 0
key down for 2 seconds). The current (I) should be at
least 1.6 A.
