Parameter
Factory setting
To:
The measuring range limit facing away from the device (echoes
from larger distances are ignored): 0.1 ... 1,500 m
1500 m
8.2.6
Configuring signal level range limits
The signal level limits define the selectable range inside of which measuring objects are
evaluated and processed further.
Echoes with level sizes below or above this range are not included in the evaluation and
therefore blanked.
The “No echo” operational status is output if no echo within the signal level range is
detected.
Parameter
Factory setting
From:
Lower signal level limit (weaker echoes are ignored):
0 to 16383 digit
0 digit
To:
Upper signal level limit (stronger echoes are ignored):
0 to 16383 digit
16383 digit
8.2.7
Configuring delay time for "No echo"
During the delay time, the "No echo" state is ignored and the last valid measured values
are output.
On the control side, this can be detected, after corresponding parameterization, by
evaluating a digital output (“Service/No echo: Delay time active” switching variable)
or the RS-422 status double word (bit 12). When using the SSI interface with the
24+8 data format, the status of the digital output named above can be read in via the
respective status bit.
Parameter
Factory setting
Delay time:
0 to 1023 cycles
50 cycles
