Page 5: Introduction
Introduction HG G-98780-A Introduction The described antennas are especially suited for outdoor applications, as the elec- tronic units are sealed within the antenna cases. All important settings, adjustable val- ues and software updates can be effected via a serial interface. Unlike Transponder Positioning System S_I13933 (128 kHz operating frequency), Transponder Positioning Antenna HG G-98780-A is operating at 13.56 MHz. -
Page 6: 1.2 Function
Introduction HG G-98780-A 1.2 Function As the antenna passes over the transponder, it energizes the latter with an energy field of 13.56 MHz. The transponder returns its code through frequency modulation to the antenna. An additional coil generates the positioning pulse. The interpreter which is integrated within the antenna decodes the transponder code. - Page 7 Introduction HG G-98780-A The measured voltage X must fall below a certain threshold (refer to Table 20 on page 31). If the above listed preconditions are met, a positioning pulse with changeable duration is generated. For the generation of a new positioning pulse it is essential that the re- ception voltage S has fallen below the threshold set for Threshold for Decoding (refer to section 5.2.2.2 on page 33) first.

Page 8: Mounting
Mounting HG G-98780-A Mounting 2.1 Transponders 2.1.1 Dimensions and Specifications The maximum reading distance for all transponders can only be achieved when the minimum distance to metal surfaces is maintained. It is recommended to maintain the minimum distances within the metal-free area (Figure 2). The impact on positioning ac- curacy and range also depends on the size and distance of metal parts. -

Mounting HG G-98780-A 2.2 Antenna HG 98780-A ATTENTION! Make sure the antenna is mounted correctly with regards to its reading side! Mounting side Bore hole ø 6,5 mm approx. 20 mm Bore hole ø 10 mm up to 140 mm 4 Screws (not in the scope of supply) Reading side... - Page 10 Mounting HG G-98780-A In order to prevent any adverse effects on the system: The space above and around the antenna should be metal-free. Do not operate the reading antenna while the reading side is located directly above a metal surface, as this would mistune the antenna severely in such a way that the power consumption of the output stage would increase considerably.
