5 Mounting
5.1 Overview of mounting procedure
The procedure for mounting the device is divided into the following steps:
1. Select a suitable mounting location for the device.
The mounting location and position depend on the following factors:
°
Identification task
°
Working range of the device ( see "Read range", page 16 )
°
Transponder used
°
Environmental influences
2. Mount the device at the intended reading point and temporarily align the device
to the object with transponder. Make sure that there is a suitable distance to the
object.
3. If required, mount the read-cycle sensor for object-specific triggering.
After the electrical installation is complete and while adjusting the device parameters to
suit the application:
4. Finely align the device to the object and adjust it.
5. Test for successful reading and writing of the device in operational use of the
application.
5.2 Preparation for mounting
5.2.1 Installation requirements
Space requirements
For the typical space requirements, see the:
• Dimensional drawing of the device see "Device view", page 15 and propagation of
the UHF field, see "Read range", page 16 .
The device does not require any physical or visual contact with the transponders.
However, align the device with the reading space.
Environmental influences
• Comply with technical data, such as the permitted ambient conditions for oper‐
ation (e.g. approved region, ambient temperature range, ground potential),
see
"Technical data", page 47 .
• To prevent condensation, avoid exposing the device to rapid changes in tempera‐
ture.
• To prevent additional external heating of the device, protect the device against
direct and indirect sunlight.
• In order to avoid reflections of the UHF waves and any associated physical phe‐
nomena, make sure if possible that there are no metal surfaces on the side of the
device in the direction of the transponder.
Possible disturbances of the UHF field caused by reflections of the UHF waves
are:
°
Overreaches
°
“Holes” (destructive interferences)
• To avoid attenuation of the UHF field by absorption, exclude the following between
device and transponder:
°
Electrically conductive material, e.g. liquids (water)
°
Persons or animals
