1.1.2 The operating menu
Structure of the menu
The parameters of the Prosonic S are organized in an operating menu (consisting of a main menu
and several submenus). Parameters which are related to each other are comprised in a common
parameter set. To simplify the navigation within the menu, a five-digit position code is displayed
with each parameter set.
•The first digit (1) specifies the submenu
1)
:
– L: "level"
– F: "flow"
– A: "safety settings"
– R: "relay/controls"
– O: "output/calculations"
– D: "device properties", "calibr. display" and "sensor management"
– I: "system information"
– S: "service" (only available if the service password has been entered)
Diagrams of the submenus can be found in the Chap. 12, "Operating menu".
•The second digit (2) is used if the parameter set occurs several times within the Prosonic S (e.g.
for different inputs or outputs).
Example:
– O1201: "allocation current" for output 1
– O2201: "allocation current" for output 2
If the parameter set occurs only once wihtin the Prosonic S, "X" is indicated at this position.
•The last three digits (3) specify the individual parameter sets within the submenu.
Locking
Locks the instrument against parameter changes.
The instrument can only be unlocked again by the keys.

does not work for these sensors.
"
Caution!
After exchanging a sensor, observe the following:
The automatic sensor recognition is also active after a sensor has been exchanged
4)
. The Prosonic S
recognizes the type of the new sensor automatically and changes the "detected" parameter if
required. The measurement continues without a break.
Nevertheless, in order to ensure perfect measurement, the following checks are required:
•Check the "empty calibration" and "full calibration" parameters. Adjust these values if
required. Take into account the blocking distance of the new sensor.
•Go to the "distance correction" parameter set and check the displayed distance. If required,
perform a new interference echo suppression.

2.1.6 "LVL N linearisation" (N = 1 or 2)
The "linearization" is used to convert the level into other quantities. Especially, it can calculate the
volume or mass within a vessel of arbitrary shape. The Prosonic S provides different linearization
modes for the most common types of vessels. Additionally, a linearization table for arbitrarily shaped
vessels can be entered.
"type"
Use this parameter to select the type of linearisation.
Selection:
• none
In this linearization type the measured level is not converted but displayed in the selected level
unit (see above, "unit level").
• linear
In this linearization type the displayed value is proportional to the measured level.
The following additional parameter have to be specified:
– the unit for the linearized value, e.g. kg, m

2.1.7 Interference echo suppression: Basic principles
The "check value" and "distance mapping" parameters are used to configure the interference
echo suppression of the Prosonic S.
The following picture shows the operating principle of the interference echo suppression:
L00-FMU90xxx-19-00-00-yy-017
A The envelope curve (a) contains the level echo and an interference echo. Without interference echo suppression,
the interference echo is evaluated.
B The interference echo suppression generates the mapping curve (b). This curve suppresses all echos within the
range of mapping (c).
C From now on, only those echos are evaluated, which are higher than the mapping curve. The interference echo is
below the mapping curve and is therefore ignored.

Note!
In order to include all interference echos, the interference echo suppression should be performed
with the level as low as possible. If during commissioning the vessel can not be sufficiently emptied,
it is advisable to repeat the interference echo suppression at a later point of time (as soon as the level
reaches nearly 0%).
2.1.8 "LVL N check value" (N = 1 or 2)
L00-FMU90xxx-19-00-00-de-016
"actual distance N" (N = 1 or 2)
Displays the currently measured distance D
display
.
"check distance"
Use this parameter to state if the displayed distance D
display
matches the real distance D (measured
by a rule for example). Based on your selection, the Prosonic S automatically proposes a suitable
range of mapping.
You have got the following options:
• distance = ok
Choose this option if the displayed value D
display
matches the real distance D.
After selecting this option, the Prosonic S changes to the "LVL N distance mapping" parameter
set. The preset range of mapping is identical to D. That means: all interference echos above the
current product surface will be suppressed by the mapping curve.
• distance too small
Choose this option if the displayed value D
display
is smaller than the real distance D.
In this case the currently evaluated echo is an interference echo.
After selecting this option, the Prosonic S changes to the "LVL N distance mapping" parameter
set. The preset range of mapping is slightly larger than D
display
. Therefore, the currently evaluated
interference echo is suppressed by the mapping curve.
If after the mapping D
display
is still too small, repeat the mapping until D
display
matches the real
distance D.
• distance too big
Choose this option if the displayed value D
display
exceeds the real distance D.
This error is not caused by interference echos. Therefore, no interference echo suppression is
performed and the Prosonic S returns to the "level 1(2)" submenu. Check the calibration
parameters, especially the "empty calibration" and the "application parameters".

The Prosonic S changes to the "LVL N distance mapping" function, where you can define the
required range of mapping.
2.1.9 "LVL N distance mapping" (N = 1 or 2)
"actual distance N" (N = 1 or 2)
Displays the currently measured distance between the reference point of the sensor and the product
surface. Compare this value to the real distance in order to find out if currently an interference echo
is evaluated.
"range of mapping"
Use this parameter to specify the range of the mapping curve. Normally, a suitable value has already
been entered automatically. Nevertheless, you can change this value if required.
"start mapping"
Select "yes" in this parameter in order to start the mapping. When the mapping is finished, the state
is automatically changed to "enable map".
The "LVL N state" parameter set appears, in which the currently mesaured level and distance are
displayed. Compare the displayed distance to the real distance in order to decide if a further mapping
is necessary.
If yes: Press the left-arrow key () in order to return to the "LVL N dist. map" parameter set.
