5. Functional Description
Important Note:
The antenna builds in conjunction with the Reader Module a tank circuit creating high voltage at the an-
tenna terminals. Please avoid any contact to these antenna terminals during operation of the Reader and
especially keep children at a safe distance from the device.
The antenna activates through its high resonance voltage a transponder which is held close enough to the antenna,
receives data from the transponder and provides the information to the RF reader module, which is able to decode the
information.
Any electrical noise (electric wires, motors, switching power supplies, fluorescent lamps, monitors, laptops, etc.)
nearby the antenna or the antenna cable may interfere with the used frequencies and disturb the proper reading of
transponders. Please avoid any of above mentioned noise sources close to the antenna module.
6. Connections
For proper connection of the two antenna wires to the RF reader module or the power module please follow the in-
structions in the corresponding user guide.
The antenna module can be mounted both on a wall or flush-fitting in a 60mm switch box.
Mounting on a wall can be done with two screws M3 or with the attached double sided self adhesive tape.
Please take into care that no metal parts are close by the antenna (distance > 5 cm).
If the antenna module is mounted as a sandwich assembly together with the RF reader boards, please keep a distance
of min. 2 cm between the module and the reader pcb.
The cable is fixed at the antenna module. For proper mounting on a wall one can remove the thinner part of the side
wall of the antenna. This allows to route the cable on the side of the module.
The cable (LiYY) has a length of 1,5 m with a twisted pair of 0,14 mm² wires. The length should not exceed 1,5 m as
this could reduce the reading capability of the RF reader.
Please take care of not bending the antenna module during assembly. This might break the coil or cable wires inside
the antenna module.
7. Putting into Operation
If the RF reader (with power module) and the antenna are connected properly, the reader can be put into operation..
8. Care, Maintenance and Disposal
Besides providing the specified voltage and its intended use as an antenna module for the RF reader modules the
antenna module does not require any special care or maintenance.
An antenna module that highly unexpected has become unusable must be disposed of observing all relevant legal
regulations.
9. Debugging
If all notes and regulations of this and other relevant Operation Manuals are observed correctly there should be no
unexpected malfunctions. If this nevertheless happens to be the case, please do not attempt to make any own repairs.
Return the device to your point of purchase and have it checked and possibly repaired by a qualified engineer. Open-
ing or improper handling of the devices will invalidate any guarantee.
