VEGA VEGASON 71 - 2 … 75 - 2 - Manual (Page 15)

Start-up
71 - 2 … 75 - 2 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 sensors 1 and 2 adapted to
the vessel feature and operate with the
parameters of the VEGA-adjustments.
Level measurement 1
Level measurement 2
Sensor 2 determines in vessel 2 the actual
distance of 9,50 m
Sensor 1 determines in vessel 1 the actual
distance of 9,20 m
Optimizations are necessary for sensor 1
and / or sensor 2
