Safety information
Observe the following safety instructions for handling ultrasonic sensors:
„
The surface to which the ultrasonic sensor is mounted must be even and
must be at least 2 mm larger than the ultrasonic sensor (this is required
to protect the drainage holes in the rear against direct high-pressure
cleaning).
„
Ultrasonic sensors must not to be mounted in a U-profile because this
could cause reflections. WABCO recommends to mount the ultrasonic
sensors mechanically protected to avoid damage.
„
The ability to detect objects largely depends on the ultrasonic sensors'
positioning on the vehicle. Make sure that the ultrasonic sensors are
installed at a height of at least 40 cm.
„
No other vehicle components should be installed within the ultrasonic
sensor's range of vision.
„
The rate of detection depends on object surfaces:
„
Ultrasound is best reflected by smooth surfaces that are positioned at a
right angle to the sound's direction.
„
Small and unfavourable surfaces such as meshed structures, furry
or hairy surfaces at an oblique angle to the sound's direction are not
detected so easily.
