Sensors (5-2-5) - Husqvarna Automower 210 C Technical Manual

2. SPECIAL MENU FUNCTIONS
Restarts = an indication that the loop system is
•
restarting. Within 5 – 10 seconds after the function
starts, the restart value stabilises. When the value
continues to change this indicates that the system
is affected by interference or is defective.
The value for Ar is shown when you press Arrow up.
When the rear loop sensor is malfunctioning the Ar
value is constant and the Quality value is 0 %.
The Automower must stand in a special test position
®
to receive usable values when testing the F- and
N-signals. This means the nose of the mower is partly
edge to edge with the charging station base plate,
partly to the right of centre. See the picture opposite.
The value for the F-signal should be above 300 and
the value for the N-signal should be above 100.
When one of the values is lower than 300 respective
100, there is probably a coil fault in the charging
station plate (see page 89 to replace the plate). The
loop sensors on the Automower

Sensors (5-2-5)

The easiest way to test the sensors is when the
Automower ® is at a standstill. The following values
indicate:
• Collision = position of the right and left collision
sensors. To test the collision sensors: Hold the
handle on the underside of the Automower
Press on different parts of the body. The display
shows None, Both, Left or Right. Continue to
press on the body until you see that both
collision sensors work.
• Lift = position for the lift sensor. To test the lift
sensor, lift up the front part of the body. When
the body is lifted up, the lift sensor is activated
and YES is shown on the mower's display. When
the mower is in the lowered position NO is
shown.
• Tilt X and Tilt Y = the movement of the angle
sensors where X is the inclination front/rear
and Y the inclination left/right-hand side. When
Automower ® is horizontal the values should be
max ±3. Inclination up and to the left give a
negative values.
could also be faulty.
