6. TROUBLESHOOTING
The parameter for the type of
robotic lawnmower is different
in the MMI circuit board and
main circuit board.
An object is obstructing the
robotic lawnmower.
The contact between the
charging strips and contact
strips may be poor and the
robotic lawnmower has made
a number of attempts to
charge.
There is an object in the way
of the robotic lawnmower
preventing it from leaving the
charging station.
The robotic lawnmower slides
on the charging station's
antenna plate.
The battery is being charged
with too high a current.
The robotic lawnmower is
set to the Secondary area
operating mode.
N/A
The parameter can only be entered at
the initial programming of the main circuit
board. It may not be changed afterwards.
Replace the main circuit board and ensure
that the correct robotic lawnmower model is
selected.
A used MMI circuit board can be used
only if it has previously been fitted to the
same type of robotic lawnmower. Thus,
one cannot, for instance use an MMI
circuit board in a Husqvarna 320 if it has
previously been fitted to a Husqvarna 330X.
Remove the object.
Put the robotic lawnmower in the charging
station and check that the charging strips
and contact strips make good contact.
Remove the object.
Clean the antenna plate.
Fault in the transformer or wrong type of
transformer alternatively charging station is
being used.
Program the mower with the most recent
main program. See 4.3.4 Programming on
page 47.
Put the mower in the charging station. This
behaviour is normal and no further action is
required.
