Each of the screen menus contains important system variables in the first line (refer
also to Table 16), as they also appear in the output telegram (described in section
4.2.4.1.1 on page 17). The last line on the screen contains possible status messages,
if e.g. predetermined value ranges have not been observed during input.
Other menus are activated by pressing the (characters in brackets). Before altered
values are transferred into the permanent memory, the pass word
815
has to be en-
tered by pressing
. This prevents unintended alterations of values. With
the val-
ues are saved after alteration and input of the password.
System errors are explained in plain text upon pressing
.

Description of the system variables
S
Measured voltage of the sum coil within the cover of the casing
in samples (max. 1023).
X
Measured voltage of the difference coil within the cover of the
casing in samples (max. ±1023).
Code
The 32 infobits of the transpondercode in hexadecimal notation.
The code will be deleted, if the voltage decreases below the
“threshold for decoding” (refer to 5.2.2.5 on page 35).
Read
Number of readings per transponder crossing. This value is pre-
served until another transponder is detected. It is also deleted
through Noise.
Frx [Hz]
and
Ftx [Hz]
Display of important system frequencies for transmission and
reception. Those frequencies are permanently controlled and
output via the system status.
U [mV]
Supply voltage of the processor board with an accuracy of
100 mV. Due to several protection methods it is always a bit
lower than the supply voltage of the antenna.
I [mA]
Current consumed by the positioning device, accuracy: 10 mA.
T [Grd.C]
Temperature measured within the device. The sensor is located
close to a cooling sheet. Output in 5
o
steps.
E
State of system in hexadecimal notation. The meaning of each
bit is explained in Table 6 on page 18.
N
Number of reading errors per transponder crossing. This value is
stored until a new transponder has been detected.
