VEGASON 51K … 53K 41
The adjusted percentage
value is written in the sensor
and the distance correspond-
ing to the percentage value
flashes.
With the " +“ or "–“-key you can
co-ordinate a product dis-
tance (example 5,85 m) to the
previously adjusted percent-
age value. When you do not
know the distance, you have
to sound.
The adjusted product dis-
tance is written in the sensor
and the indication stops flash-
ing.
You have thereby adjusted the lower product
distance as well as the percentage filling
value corresponding to the lower product
distance.
Set-up
Under the menu point " Adjustment“ you in-
form the sensor with which meas. range it
should operate.
You can carry out the adjustment without and
with medium. Generally you will carry out the
adjustment without medium as you can then
adjust without filling cycle.

(Max-adjustment)
The max. adjustment (upper product dis-
tance) is made in the same way (example:
100 % and 1,270 m).
Note:
The difference between the adjustment val-
ues of the lower product distance and the
upper product distance should be as big as
possible, preferably at 0 % and 100 %. If the
values are very close together, e.g. lower
product distance at 40 % (3,102 m) and
upper product distance at 45 % (3,331 m),
the measurement will be inaccurate.
A level characteristic is generated from the
two points. Even with smallest deviations
between actual product distance and ad-
justed product distance, the slope of the
characteristics will be considerably influ-
enced. Thereby small failures multiply with
the adjustment when the adjustment points
are too close together to more considerable
errors at the output of the 100 %-value or the
0 %-value.
