4.2.3 "value level N" or "value flow N" (N = 1 or 2)
(only available for the option "customer specific")
Use this parameter to specify the output value in the case of an echo loss.
4.3 "delay echo loss"
4.3.1 "delay sensor N" (N = 1 or 2)
Use this parameter to define the delay time for echo loss.
After an echo loss, the instrument waits for the time specified in this parameter before generating
an alarm. Thus the measurement is not interrupted by short-time interferences.
4.4 "safety distance"
4.4.1 "safety distance sensor N" (N = 1 or 2)

⇒
safety distance AX104
saf.dist. sen 1:
saf.dist. sen 2:
Use this parameter to specify a safety distance
for the sensor.
The safety distance is located immediately
below the blocking distance. If the level projects
into the safety distance, an alarm is generated.
