8.2.4 Symptoms during charging
Symptom Cause Action
Both the mowing and charging
times are shorter than usual
Low battery capacity. Perform a
Battery test
to determine the
battery’s capacity. Refer to
Auto test on
page 10
.
The product never leaves the
charging station
The parking mode is activated. Restart the product on main or secondary
area.
Schedule settings are preventing the
product from leaving the charging station.
Check the Schedule settings. Also check
that the clock shows the current time.
The product never becomes fully charg-
ed.
Check that the product is receiving the
charging power. Check that the value for
the current corresponds with the guide-
line values. If the charging plates appear
to be burnt or coated, clean them using a
fine grade emery cloth. Check that the
rear sensor module and the charging
tower are correctly connected, and that
they are not damaged.
If the problems remain, try the following:
• Replace the charging tower.
• Replace the rear sensor module.
The power supply is faulty.
Check that the product is receiving the
charging power. Check that the value for
the current corresponds with the guide-
line value in
The battery system on page

8.3 LED indicator lamp on the charging station
Always start by checking the LED in the charging
station. This usually provides a good indication of where
troubleshooting should begin.
Colors in the charging station’s LED
Color Status
Solid green light All signals are OK
Green flashing light ECO mode
Red flashing light Malfunction in the charging
station F and N signal
Solid red light Fault in the circuit board,
or incorrect power supply
in the charging station.
In the event of faults in the charging station follow the
instructions in the Operator's manual and below.
8.3.1 Green solid light
The LED in the charging station is solid green, but
neither the front or rear loop sensor detects any loop
signal:
1. Generate a new loop signal. Test the product and
continue with step 2 if the product still cannot find
the loop signal.
2. Replace the circuit board in the charging station.
Refer to
To replace the circuit board in the charging
station on page 31
.
8.3.2 Green flashing light
ECO mode is enabled in the product and no loop signals
are therefore being transmitted in the loop wires in the
charging station baseplate. If the product has been
removed from the charging station manually without
pushing STOP before, ECO mode may still be enabled
(green flashing light) so that the loop system is not
transmitting any signals. To start the loop system
manually:
1. Place the product in the charging station and push
the STOP button.
8.3.3 Red flashing light
A red flashing light is most likely an interruption in the N
or the F-wire in the charging station’s antenna.
