1 Introduction This document will describe the components of the reader system ARE K1 / PFB and the procedure how to do the set up of the reader.
The antenna must not be brought next to a metal surface. This could lead to a significant change of the properties of the antenna circuit, which in turn reduces the reading range considerably. Please take account to the installation manual of the antenna! Environmental electromagnetic noise may also reduce the specified reading performance. Special hints to overcome these problems are documented in chapter 3 and in the installation manuals of the antenna.

5 Installation To get the specified reading performance it is necessary to do the installation carefully step by step as it is described in the chapters below. All the work must be done by well educated people. 5.
Attention! While closing the box take cake, that no cables are shut between top and bottom of the box. In addition the seal ring in the top of the box has to be checked, to ensure tightness of the box. 5.2 Grounding of the Reader Box To get reliable reading results, the reader must be grounded. The connector is placed at the side of the housing (6.35 mm flat contact). To avoid problems with electromagnetic compatibility, the cable to ground ought to be very short with low impedance.
5.3.3 Mounting of the Power Supply Cable The power supply cable must be mounted in following steps: • Prepare the SAB cab according to chapter 5.3.2 • Remove all inner parts from the cable pipe at the SAB cab (1) ( nut (5), pipe(4) and cable fastener (3)) (see Figure 5-3) • Put all the removed parts ( nut (5), pipe (4), cable fastener (3)) and the cable pipe of the SAB cab as well (1 to 4) to the cable.
• Fasten nut (5) of the cable pipes with the right tool (17mm). • Do this carefully, to ensure the tightness of the protection class of IP 65. 5.3.5 Plug in of the SAB Cab Attention ! Before plugging the SAB cab to the connectors of the reader, make sure that the grounding of the device is well done. Otherwise the electronic may be destroyed by electrostatic discharge. 2 1 A 1 B A 2 Figure 5-5: Plug-in of the SAB Cab • • • • Put on the sealing ( (2) in Figure 5-5 ) to the SAB cab (A).
5.3.9 Assembling of the Data Cable (Profibus Network) The connection from the ARE K1 / PFB to the master PLC is made using the interface cable. This must be mounted in following steps: • Prepare the SAB cabs "Profibus" in the same way like subchapter 5.3.2 . • Put all the removed parts ( nut (5), pipe (4), cable fastener (3)) and the cable pipe of the SAB cab as well (1 to 4) to the cable.
5.3.10 Plug in of the Profibus SAB Cabs Attention! Before plugging the Profibus SAB cabs to the connectors of the reader, make sure that the grounding of the device is well done. Otherwise the electronic may be destroyed by electrostatic discharge. 6 Definition of the Profibus Slave Attributes Before bringing the ARE K1 / PFB into operation in the Profibus net, the adress of the slave has to be adjusted.
6.1 Operation at the End of a Network Line If an ARE K1/PFB is used at the end of a network line, the termination has to be activated as described in the previous subchapter. In this device only one data cable is connected to the reader box. It is indifferent, which one of the both ports is used for the data cable. To ensure the tightness of the the protection class of IP65 the port unused has to be closed with a plain SAB cab.
7.1 Indicators The device has 9 indicators. OP ANT Run READ BusFail NoREAD RX ERR Tx Figure 7-1: Position of all LED Indicators Their function is: OP: ANT: READ: NoRead: ERR: Run: BusFail: RX: TX: 8 flashing as long as the microprocessor is working properly - life indication on if antenna is operated on if last read was successful on if last read was not successful on if a hardware error was detected, i.e.
8.1 Profibus Slave: Configuration and Parametrization The ARE K1 / PFB has one configuration only. Only the seven standard Profibus parameters are defined. So it is not necessary, to handle with device specific parameters (User_Prm_data). If the device is parametrized successfully it is ready for data tranfer. The green LED indicator "Run" is on. Attention ! Inside of a network line, it’s not allowed to install more then 32 reader devices.

Caution ! Never mount or place the antenna on extended metal parts. Do not bring another antenna very near to the operated antenna (second antenna operated or not). In both cases there is a risk, that the antenna may be destroyed. Such defects are not covered by the warranty. An unusual high current consumption can be a hint for such not allowed configuration 11 FCC Information Federal Communications Commission (FCC) Statement 15.
