4.2 Determining the sensor installation position
See fig. 2 to fig. 5
I
Note the following during installation:
 The distance from the sensors to the ground should be at least 40 cm and
a maximum of 50 cm (fig. 2).
 For the sensors to function optimally, the angle of the sensor to the road
surface should be 90° (fig. 2). The angle may not be less than 90°, as
the road will otherwise be interpreted by the sensor as an obstacle.
 The sensor holders included are suitable for all standard bumpers. Should
the vehicle bumper be mounted at a steep angle, 20° sensor holders with
a cover ring are available as an optional extra (see chapter “Accessories
for WPS 900F/WPS 910” on page 29).
 The sensor holders included are not suitable for installation in metal
bumpers. If your vehicle has metal bumpers, you will need special sensor
holders with a silicon ring (see chapter “Accessories for
WPS 900F/WPS 910” on page 29).
 Note that the sensor holder depends on the installation height and the
angle of the bumper. Select the right sensor holder and the appropriate
drill diameter by consulting the table in fig. 2. The instruction manual
shows how to install the standard sensor holder (fitted from the inside of
the bumper), which produces the best visual result. Alternatively, the sen-
sors can also be fitted using the sensor holders with cover ring which are
provided.
 Install the sensors in the correct position (fig. 5):
NOTE
The sensors must be correctly aligned for the device to work prop-
erly.
If they point to the ground, irregularities and bumps on the surface
may be interpreted as obstacles. If they point too far up, obstacles
will not be detected at all.
