The collision sensors are the sensors that detect when
the mower has run into a fixed object. To test the two
collision sensors:
1. Hold the handle on the underside of the
Automower.
2. Press on different parts of the body.
In the Active collision sensors box you should now
see None, Left, Right or Both. This is also shown
in the picture to the right of the screen.
3. Continue to press on the body until you see that
both sensors work. Make sure the mower does not
indicate a collision when it is untouched.
The tilt sensor is the sensor that detects the mower's
inclination in relation to the horizontal plane. The
X-angle indicates a front – rear inclination and the
Y-angle a left – right inclination.
When Automower stands on a perfectly flat surface,
the values should be about +/-3. Otherwise the tilt
sensor needs to be calibrated. When the mower is
tilted up and to the left the values will be negative.
To calibrate, i.e. reset the tilt sensor:
1. Place the Automower on a flat surface.
2. Click on Tilt sensor calibration.
3. Click OK when prompted to place the mower
horizontal.
The message Calibration OK is shown once
calibration is complete.
The lift sensor is the sensor that detects whether the
mower has been lifted from the ground. To test the lift
sensor:
1. Lift up the front part of the body.
2. When the body is lifted up, YES is shown. When
the mower is in the lowered position NO is shown.
Manual test: Loop
In order to test the loop signals and to receive useful
values the test must be performed where there is a
boundary wire and a charging station installed. It must
be a test surface of at least a few square metres
around the charging station. It also requires the mower
to be connected to the installation.
The values for the different loop signals are shown in
the Loop signals box. These values are an indication of
how well the loop system is functioning. The loop
signals can be measured through the front or the rear
loop sensor. Select which sensor is to be tested by
checking either Front loop sensor or Rear loop sensor.
Point to a value or a heading and the relative field and
loop are shown in the picture at the bottom of the
screen.
