subsequently diminishes the farther away from the wire
you get. Outside the guide loop, the signal is negative
and the strength of the signal diminishes more rapidly.
Note: The product always tracks the left side of the
guide wire when facing the charging station, i.e. the
product follows the negative values on the guide signal.
CAUTION: Do not lay the guide wire at 90°
angles or less. Lay the wire in two 135° angles.

3.6 Charging station
The placement of the charging station must be well
planned in order to give the best installation and
operation of the product. Refer to
station in the Operator's Manual.
Note: The battery is spared if charged in the lowest
possible ambient temperature. Consequently, it is
beneficial if the charging station is placed where it is
shaded, especially during the warmest parts of the day.
When the battery level has dropped to 600 mAh or
the battery voltage has dropped to 17.5 V, the product
shuts down the cutting motor and starts searching for
the charging station.

5. Rear Loop sensor
6. STOP sensor
CAUTION: Some sensors consists of a Hall
sensor and a magnet. Since the magnets have
a south and a north pole, it is important that the
magnet is fitted correctly.
Note: There are no sensors for collision in the product.
Collision detection is registered from the power variation
of the wheel motors.
3.7.1 Tilt sensor
The tilt sensor is a sensor on the main board that
detects the product's inclination in relation to the
horizontal plane. The X-angle indicates front to rear
inclination, and the Y-angle indicates left to right
inclination. The value from the tilt sensor is used, among
other things, to correct the speed of the drive wheels
when mowing in steep slopes.
3.7.2 Lift sensors
The lift sensors detect if the product is being lifted off
the ground. This is done with the help of the mechanical
design and magnets. If a lift signal is indicated, the blade
disc stops immediately. The product tries extrication
maneuvers by reversing and turning several times.
3.7.3 Loop sensors
The loop sensors measure the signals that the charging
station sends through the boundary loop (A signal), the
guide loop (Guide signal) and the baseplate (F signal).
The signals are used to control the product and keep
the product inside the work area. The product can only
detect the signals if it has been paired with the charging
station. Refer to
3.7.4 STOP sensor
The STOP sensor detects if the STOP button is pushed
6
down. If the STOP signal is indicated, the product and
the blade disc stop immediately.
Note: There is a magnet and a Hall sensor in the
STOP button, which means that there is no connection
between the hatch and the STOP button.
