5. Save settings with
[OK]
and move with
[ESC]
and
[->]
to the max.
adjustment.
The min. adjustment is finished.
For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.
Proceed as follows:
1. Select with
[->]
the menu item Max. adjustment and confirm with
[OK]
.
2. Edit the percentage value with
[OK]
and set the cursor to the
requested position with
[->]
.
3. Set the requested percentage value (e.g. 90 %) with
[+]
and save
with
[OK]
. The cursor jumps now to the pressure value.
4. Enter the pressure value for the full vessel (e.g. 900 mbar) cor-
responding to the percentage value.
5. Save settings with
[OK]
The max. adjustment is finished.
For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage and vessel volume. The linearization applies to the measured
value indication and the current output.
Caution:
Note the following, if the respective sensor is used as part of an over-
fill protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer
necessarily linear to the filling height. This must be considered by the
user especially when setting the switching point on the limit signal
transmitter.
Since the parameter adjustment of the Function Block 1 (FB1) is very
comprehensive, it was divided into various submenu items.
