6Chapter 2: Introduction HG G-98780-A
2Introduction
The described antennas are especially suited for outdoor applications, as the electronic
units are sealed within the antenna cases. All important settings, adjustable values and soft-
ware updates can be effected via a serial interface.
Unlike Transponder Positioning System S_I13933 (128 kHz operating frequency), Transpon-
der Positioning Antenna HG G-98780-A is operating at 13.56 MHz. This ensures sufficient
frequency separation to interference sources such as, e.g., drives, power converters and
switching power supply.
Both systems supply a similarly structured output format in which additional system infor-
mation can be configured by the user. This information can, for example, be saved in a visu-
alization system and enables statements about the condition and availability/ accessibility
of the transponders and antennas. This system description applies to devices with the firm-
ware 98780B2 version 1.06 and higher.

7Chapter 2: Introduction HG G-98780-A
2.2 Functional Description
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.
Furthermore several antenna parameters, e. g. current consumption and supply voltage, are
measured and, if desired, added to the serial output protocol.
The serial signal is made available via potentially separated RS 422 or RS 232 interfaces. In
addition, the positioning pulse is dc-insulated. Furthermore, CAN Bus or Profibus interfaces
are provided optionally. The following variants are available, they can be distinguished by
the second to last character of the product number, e.g. HG G-98780ZA.
As an option, the serial signal can be converted into a 16 bit parallel output signal (24 Volts
switched) for the code within an external interface device. This interface device is suited for
mounting rail (top-hat rail) installation and should be installed in a place protected from any
environmental influences (see section 5.3 on page 25).
2.3 Positioning Pulse
For the generation of the positioning pulse, it is necessary that the following preconditions
are met:
– The reception voltage S (refer to Table 20 on page 30) must exceed the set threshold
for Level for Positioning (refer to section 6.2.2.2 on page 31).
– A transponder code must be decoded without error.
– The measured voltage X must fall below a certain threshold (refer to Table 20 on
page 30).
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 reception
voltage S has fallen below the threshold set for Threshold for Decoding (refer to sec-
tion 6.2.2.2 on page 31) first.

8Chapter 2: Introduction HG G-98780-A
Thus only one pulse per transponder crossing is possible. Therefore, if a vehicle/crane stops
above the transponder after the positioning pulse was generated and then changes its di-
rection of travel, no renewed positioning pulse is generated during the center crossing!
Positioning Accuracy
As the field compensation for the corresponding measuring coil is not infinitely sharp and
is also depending on the reading height (refer to Appendix, Section A on page 44), the po-
sitioning pulse is generated at different but reproducible locations, depending on the direc-
tion of travel. Since the antenna is not aware of its direction of travel, but depends on the
physical effect of the field strength, only the vehicle/crane control can carry out the direc-
tion-depending compensation. The appendix, section B on page 46 shows the locations of
the positioning pulse related to the X and Y coordinates and the reading height.

3Mounting
3.1 Transponders
3.1.1 Dimensions and Specifications
The maximum reading distance for all transponders can only be achieved when the mini-
mum distance to metal surfaces is maintained. It is recommended to maintain the mini-
mum distances within the metal-free area (Figure 2). The impact on positioning accuracy
and range also depends on the size and distance of metal parts.
Figure 2 Minimum iron-free area around Puck Transponder HG 70661
As rule of thumb it can be said that if the metal-free area behind the transponder has to be
at least of the same range as the reading distance between transponder and antenna. The
reception of the transponder signal will be largely unattenuated (also refer to Table 26 on
page 48). It is essential, that the transponder does not dip into the meshs/loops of steel
reinforcement grids. Single metal rods, on the other hand, hardly have any influence on
the performance.
3.1.2 Mounting Instructions
The Transponders may be mounted on even ground using a metal screw and a washer. The
maximum fastening torque is not allowed to exceed 4 Nm. The diameter of the metal wash-
er should not be max. 18 mm. For further information please refer to the transponder data-
sheet HG G-70661.

3.2 Antenna HG 98780-A
ATTENTION!
Make sure the antenna is mounted correctly with regards to the orientation of its reading
side!
Figure 3 Mounting the antenna
The casing of the antenna has bore holes for 4 screws (also refer to Figure 4 below). We rec-
ommend the usage of M6 hexagon socket screws. The length of the screws depends on
where the antenna is to be mounted. Please make sure that in the direction of travel there
is enough free space for the connections. Depending on the variant up to 140 mm are need-
ed (the picture above shows the ZA/WA variants).

11Chapter 3: 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. YOu can find more
information in the sections C on page 48, D on page 49 and E on page 50.
– 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.
– Perfect transponder readings are only guaranteed if the transponders are placed
within max. ±4 cm tolerance from the center line of the antenna! Outside these lim-
its, the transponder readings become less reliable due to decreasing signal levels.
Note
Whenever the antenna is operated at temperatures below 0oC, it is necessary to use the
integrated heater! As the warm-up time with heater at -20oC surrounding temperature is
approx. 1 hour, the heater should be connected to a stand-by power supply.
3.3 Interface HG 06150ZA/XA (optional)
The optional interface has to be mounted in a climated enclosure on a mounting bar with
the following connections:

12 Chapter 4: Installation / Commissioning HG G-98780-A
4Installation / Commissioning
Note
Check the operating voltage before connecting! The cable should not lie directly beside
power supply cables.
Connect all necessary cables. For the next commissioning steps, connect a laptop with the
serial interface of the antenna. Antenna variants with RS422 interface (HG 98780ZA/XA) re-
quire an appropriate interface converter. This interface converter is not included in the
scope of supply of this system. For further information, please refer to the introduction in
chapter 6 on page 26. Then start the monitor program as described in section 6.2 on page
27.
Default values: In default the system uses the values of the file 1 (Mon3964r.txt; as list-
ed in part 6.2.1 on page 27) with 9,600 Baud. Please keep in mind that another user could
have changed these values.
1. Move a transponder into reception range.
The voltage Sshould increase significantly. The code should be detected immedi-
ately and the number of readings has to be continuously counted up to 65535. When
moving the transponder in driving direction over the center axis of the antenna, a
positioning pulse should be generated.
2. For setting the decoding thresholds (refer to section 6.2.2.2 „(T)ime & Code“ on page
31) it is useful, to record a complete test run along the transponder track.
Antennas HG G-98780ZA and HG G-98780WA offer for this function the use of
the serial interface (section 6.2.2.6 „CS(V)“ on page 36) or the CAN Bus Message
Object 3 (section 5.2.6.4.4 on page 23 or 6.2.2.4 „C(A)N Parameters“ on page 34).
Antennas HG G-98780YA and HG G-98780XA offer for the same function the
serial interface (refer to section 6.2.2.6 on page 36) or the Profibus interface (refer to
section 6.2.2.5 on page 35). When using the Profibus interface, the necessary param-
eters from the 16 byte data block are System Status, Code and U-Summe.
Provided that the test run did not reveal any problems, changed parameters may be saved
and the monitor program may be terminated. Changing certain parameters requires a com-
plete system reset (switching the antenna off and on again), as described in the correspond-
ing section for the monitor program (section 6.2). This procedure ensures that the system is
commissioned correctly.

Inside the casing are the completely sealed antenna electronics and the heater. For con-
necting the antenna, the cable tails X1 and X2 (Profibus) and X3 (PosiPuls, RS422, power
supply) are being used. The integrated LED is lit for the Profibus status Data exchange.
5.2.3.2 Pin Allocations X1/X2/X3
This Profibus variant of the antenna offers up to two identical cable tails X1/X2 for Profibus
connections depending on whether a terminating resistor is included.

In addition there is a cable tail X3 for the power connection and the serial interface.
5.2.4 Positioning Pulse
The digital positioning output indicates the crossing of the center line of the antenna in di-
rection of travel (x direction). Its duration is adjustable within a millisecond pattern.
Both positioning connections are separately and not internally connected to +24 V or GND,
as a strict voltaic separation is essential for some of the systems. For safety reasons, a
20 mA current limitation has been implemented in the antenna for these outputs. In case a
24 V output is required, contact No. 9 may be connected to +24 V and contact No. 10 may
be connected to GND via a 1 KOhm resistor.

5.2.5 Switch-on Characteristics
Once the supply voltage has been applied, the antenna requires 10 s until it reacts to data
input, or outputs data protocols. During these 10 s, a software download may be started (al-
so refer to section 5.2.7 on page 24).

5.2.6 Interfaces
5.2.6.1 Serial (RS 422 / RS 232)
The serial output may be configured in several ways. The transmission rate is adjustable be-
tween 9600 and 19200 Baud, the output protocol may be chosen as “transparent“ or
“3964R“. Apart from that, the content of the telegrams is configurable, as the user may
choose from a list of parameters.
Serial commands are used for activating a system monitor. The crossing of the antenna´s
center axis in direction of travel, is shown by the digital positioning output. Its transmission
time is adjustable in blocks of milliseconds. In addition, it may be reduced to one impulse
per crossing.
5.2.6.1.1 List of system data to be output
A telegram consists of max. 15 bytes. The minimum update rate at 9600 Baud is then cal-
culated as follows
Figure 11 Formula: minimum update rate
As the transmission is binary, it is possible - when using the 3964R procedure - that further
(DLE) characters are added by this procedure. All multiple-byte variables are output either
with the highest byte or the lowest byte first (adjustable)!
The 8 bit check character is only output when using the transparent protocol. It then in-
cludes the start character. The check character (transparent protocol), cannot be removed
from the data block. It is a matter of configuration, whether data telegrams are output per-
manently according to the set update rate or only during the period, when a transponder is
within the field.

The following table shows a list of the binary codes used to describe the system status (for
bytes # 13 and 14 from Table 3):
*) These bits are deleted as soon as the transponder has left the antenna field.
Example: Status 0x0600
stands for TRANS_IN_FIELD and CODE_OK
The status 0x0002 may also arise during ordinary transponder crossings, if the code trans-
mission is aborted due to decreasing power output level. The message 0x0100
(REF_TRANS_ON) enables checking whether transmission of the corresponding switch-off
command has been forgotten (in this case, it is no longer possible to read runway transpon-
ders correctly).
