times.
Possible cause:
– Date and time incorrectly set
– Active times incorrectly set
– Machine has been operated by
unauthorised persons
Remedy:
– Set the time and date (Ö 11.10)
– Set the active times (Ö 11.7)

"High" (Ö 11.15)
Fault:
The robotic mower fails to operate during
an active time
Possible cause:
– Battery is charging
– Automatic mowing switched off
– Active time switched off
– Rain detected
– If the mow plan type "Dynamic" is
activated: weekly mowing duration has
been reached, no further mowing
operations required that week
– Message is active
– Control panel not correctly inserted
– Docking station not connected to power
supply
– Outside allowed temperature range
– Power failure
Remedy:
– Allow the battery to finish charging
(Ö 15.8)
– Switch on automatic mowing (Ö 11.7)
– Release the active time (Ö 11.7)
– Set the rain sensor (Ö 11.11)
– No further action necessary, mowing
operations are automatically distributed
over the week in the mow plan type
"Dynamic" – if necessary, start the
mowing operation in the "Start" menu
(Ö 11.5)
– Rectify the displayed fault and confirm
the message with OK (Ö 24.)
– Insert the control panel (Ö 15.2)
– Check power supply to the docking
station (Ö 9.3)
– Allow the robotic mower to warm up or
cool down – standard temperature
range for operation of the robotic
mower: +5°C to +40°C. Detailed
information is available from your
specialist dealer. #
– Check power supply. When the robotic
mower detects a wire signal again after
a periodic check, it resumes the
interrupted mowing operation.
This means that it can take several
minutes before mowing operation is
automatically resumed following the
power failure. The intervals between
the individual periodic checks increase,
the longer the power failure lasts.
