False signal suppression
Change now?
Proceed as follows:
1. Move from the measured value display to the main menu by
pushing [OK].
2. Select the menu item "Service" with [->] and confirm with [OK].
Now the menu item "False signal suppression" is displayed.
3. Confirm "False signal suppression - Change now" with [OK] and
select in the below menu "Create new". Enter the actual distance
from the sensor to the product surface. All false signals in this
area are detected by the sensor and saved after confirming with
[OK].
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
echo. The filling level would then no longer be detectable in this area.
The menu item "Extended setting" offers the possibility to optimise
VEGASON 62 for applications in which the level changes very quickly.
To do this, select the function "Quick level change > 1 m/min.".
Extended setting
quick level change > 1 m/min.
Note:
Since with the function "Quick level change > 1 m/min." the genera-
tion of an average value of the signal processing is considerably
reduced, false reflections by agitators or vessel installations can
cause measured value fluctuations. A false echo memory is thus
recommended.
This function enables reading out parameter adjustment data as well
as writing parameter adjustment data into the sensor via the display
and adjustment module. A description of the function is available in
the operating instructions manual "Display and adjustment module".
