Mounting
We recommend the following procedure for mounting the transponder antenna:
First prepare the connection cables (see section 7.2 on page 22).
Lay the connection cables in the vehicle.
Then mount the antenna at the desired position (see section 7.3 on page 23).
Close unused connectors with M12 closing caps.
7.1 Mounting the Transponders
7.1.1 Operating Conditions for Transponders
For all transponders, the maximum reading distance can be achieved if they are po
-
sitioned away from metallic surfaces. Practical tests should be carried out to clarify
the configuration!
Mounting options for the transponders:
On the road surface.
Flush in the roadway with grouting.
The reading distance is the distance between the reading side of the antenna and
the top edge of the transponder.
Transponders may not be permanently mounted in standing water. The plastic can
absorb water over a longer period of time and weaken the transponder signal.
Reinforcements laid tightly under the road surface can interfere not only with the
transponders but also with the antennas and thus falsify the position detection. The
influence on positioning accuracy and range depends on the size and distance of
metal parts.
Observe the minimum distances specified in the associated data sheets (see
1.1.2 „Additional Applicable Documents“ on page 6).
Observe the recommended minimum distances in the metal-free space
(section 7.3.4.2 on page 25). The influence on the position accuracy and range
also depends on the size and distance of the metal parts.
A minimum distance of 500 mm is required between two transponders.
NOTICE
Malfunction or detuning of the antenna
If you do not comply with the operating conditions, the position detection may be
faulty or the antenna may fail completely.
Always comply with the operating conditions specified in section 7.3 on page
23, in particular regarding metal-free areas and the routing of live cables
around the antenna.
