Commissioning
Note
Check the operating voltage before connecting! Although the RS 232 interface reacts large-
ly insensitive to interferences, the cable should not be located directly beside power supply
cables.
Connect all necessary cables. For the next commissioning steps connect a laptop with the
antenna. Then start the monitor program as described in section 6.2 on page 31.
1.
Move the transponder below the antenna
In the status line the voltage S has to rise significantly. The code has to be detected
immediately and the number of readings has to be counted up to 255 constantly.
When the transponder crosses the center axis of the antenna in driving direction, a
positioning pulse has to be generated.
2.
Remove the transponder from below the antenna
If there is no transponder in the field, the voltage S has to fall to extremely small val-
ues. The code display and an possible display of the number of readings remain. If
that is not the case, interferences in a frequency range of 64 kHz are induced.If no
errors occurred, the monitor program can be closed. Remember to save possibly
altered values. After changing certain parameters, a system reset is required (turn-
ing off and on the antenna). This procedure is explained in the corresponding chapter
of the monitor program (see chapter 6.2 „System Monitor“ on page 31).
3.
Now proceed an one-time reference transponder setup by transmitting the corre-
sponding serial command (see Tabelle 5.3.2.1.2 auf Seite 20) or by using the corre-
sponding submenu in the monitor program (see Tabelle 6.2.1 auf Seite 31).
Note
This command may only be carried out once during the commissioning, as otherwise
changes in the accuracy of the antenna remain undiscovered, as they are included in the
reference values each time a setup of the reference transponders is proceeded!
The new reference values, found during the reference transponder setup (sum. and differ-
ence voltage), are saved automatically to the parameter E
2
PROM when applying the serial
command.
4.
Now, it is recommended to protocol a complete drive. Depending on the antenna ver-
sion there are different possibilities:
Parallel interface (in the interpreter version HG G-71912YA)
Here, a logging is possible via a serial interface (see chapter 6.2.2.9 on page 41).
CAN-Bus (in the interpreter version HG G-71912ZA, XA)
Here, a logging is possible via a serial interface (see chapter 6.2.2.9 on page 41).
