71 - 1 … 75 - 1 15
Flow diagram for start-up
Connect sensors with central electronics
and supply with operating voltage.
The software version is indicated and the
fault signal reacts.
The measuring system is now ready and
starts for each separate channel with the
commissioning preliminary indication: 0.00 m
Commissioning, i.e:
1. Echo limitation from top to bottom.
2. Echo limitation from bottom to top.
3. Formation of a measuring window within
which an evaluation of the echo is carried
out.
After approx. 1 … 3 minutes the measuring
system is ready. The fault signal extin-
guishes. The sensor adapted to the vessel
feature and operates with the parameters
of the VEGA-adjustments.

Sensor determines the actual
distance of e.g. 9,20 m
