Installation / Commissioning
NOTE!
Check the operating voltage before connecting! Although the
RS 422 interface reacts largely insensitive to interferences, the
cable should not lie directly beside power supply cables.
Establish all required connections. For the next commissioning steps connect a laptop
with the antenna via a RS 422 to RS 232 interface (not in the scope of supply). Then
start the monitor program as described in section 5.2 on page 27.
Default values
By default the system starts into the mode „Monitor only“ at 9600
baud. Keep in mind that another person might have changed
those settings!
1.
Move a transponder under the antenna.
The voltage
S
should increase significantly in the status line. The code should
be detected immediately and the number of readings have to be counted up
continuously to 255. When moving the transponder in driving direction over the
center axis of the antenna, a positioning pulse should be generated.
2.
Remove the transponder.
The voltage
S
should decrease to very small values if there is no transponder
within the field. The code display and the number of readings will be preserved.
If this is not the case, there are interferences in the frequency band of 64 kHz.
3.
in case the antenna has been mounted directly on metal, it is necessary to re-
tune it accordingly. For setting the positioning and decoding thresholds (refer to
section 5.2.2.5 on page 35) it is useful, to record a complete test run along the
transponder track.
Antenna HG 98760ZC/WC
makes this possible via the serial interface (see
5.2.2.6 on page 36) or the CAN Bus Message Object 4 (4.2.4.3.5 on page 22 or
5.2.2.5 on page 35).
Antenna HG 98760YC/XC
offers for the same function via the serial interface
(refer to section 4.2.4.1 on page 17 ) or the Profibus interface (refer to section
4.2.5 on page 22). When using the Profibus interface, the necessary parameters
from the 16 byte data block are
System Status
,
Code
and
U-Summe
.
If no errors have occurred, exit the monitor program. Don’t forget to save the altered
values. If certain parameters have been changed, a system reset will be necessary
(switch off and reactivate then the antenna) as mentioned in the corresponding section
of the monitor program (section 5.2). Now the system has been put into operation
properly.
