Installation / Commissioning – Chapter 4

The following diagrams show examples of logged system data:

Figure 5

Diagram: Commissioning Protocol / insignificant interference level; shown is the sum
voltage over the travelled distance

The above diagram shows the sum voltage (in units) over the travelled distance. The
noise is in this case approx. 50 units, the transponder signal approx. 950 units. The
transponder decoding is perfect, as also shown in the following diagram:

Figure 6

Diagram: Commissioning Protocol / undisturbed Transponder decoding

During each transponder crossing, the sum voltage increases initially. Once the
threshold

Threshold for Decoding

has been exceeded, the bit

TRANS_IN_FIELD

is set. Following 4 x 8 ms (= 4 data points) the transponder

code is decoded. The duration depends on the setting for

Number of Equal

Codes

within the menu

Time & Code

. In this example, this parameter is = 2, i. e.

the newly received code is compared to two codes which were already received.
Once the center of the antenna has been crossed, the

POSI Pulse

is generated.

Its duration is adjustable. The bits

TRANS_IN_FIELD

and

CODE_OK

are deleted,

whenever the sum voltage falls below the value for

Threshold for Decod

ing

. In the shown example there is spare time of 6 x 8 ms for the generation of the

POSI-Pulse

. The velocity of crossing was 1.1 m/s (180 mm antenna length / (20

x 8 ms)

Low Interference Level

Undisturbed Transponder Decoding
