Parameters (HART)
By using SIMATIC PDM, you can display a list of all echoes in your vessel. It provides
the distance between the flange and the measuring medium’s surface, as well as
the distances of fixed targets. These may be directly used and transferred to the fix
distance list.
4.2.3.9: Auto False Echo Suppression (F = use)
Learns and records the current signal up to the suppression distance setting. These
signals are then ignored during operation.
If all signals fall below this defined threshold, then the failsafe timer is initiated.
4.2.3.A: Auto False Echo Suppression Distance (F = 2/3
vessel height)
Defines the end point of the Auto False echo suppression distance
4.2.4: Level Parameter
4.2.4.1: Level URV (= parameter 1.5)
4.2.4.2: Level URV (= parameter 1.6)
4.2.4.3: Level URV (= parameter 1.7)
4.2.4.4: MinLim Level (F = 0 m)
Lower limit value of the level (see “Functional Dimensions” on page 25)
Set the lower limit value of the level as a height above the LRV.
4.2.4.5: MaxLim Level (F = 0 m)
Upper limit value of the level (see “Functional Dimensions” on page 25)
Set the upper limit value of the level as a height above the LRV.

4.2.5: Volume parameters
To calculate the volume of the measuring medium, you need the level parameters (see
parameter 4.2.4) in the units selected according to parameter 4.1.1 and additionally a
vessel characteristic (parameter 4.2.5.7).

Determining the vessel characteristic
Select the option “Calculate” or “Calibrate/Table” as required. The selection controls the
display of Parameter 4.2.5.8.
The possibilities of each parameter are listed below. For the values associated with
Parameter 4.2.5.8: Calculate, go to page 43.
4.2.5.8: Calibrate/table
If your vessel deviates from the forms offered, the necessary data is not available or is
unknown or you need a vessel characteristic with greater accuracy you must calibrate it
by liters. You can enter reference values from a table provided by the vessel
manufacturer or do the calibration manually and enter the determined reference values.
You can only enter pairs of values consisting of level and volume.

Note: Entering the vessel characteristic with the operation and monitoring module
can be a time-consuming procedure. It can be done more quickly and comfortably
with the SIMATIC PDM software. There, an entered table can be edited simply – an
option which is only conditionally possible with the operating and monitoring module.

Parameters (HART)
The 4.2.5.8: Calibrate parameter offers the following selection possibilities:
4.2.5.8.1: Calibrate
Here you can enter up to 50 reference values whose levels SITRANS LR 400 measures.
Enter the appropriate volume (determined by manual calibration).
If you access this parameter, first the currently measured level is displayed. Accept it by
pressing . Enter the appropriate volume, save it by pressing or reject it by pressing
.
Then the device displays the “Calibrate” selection again. Access again (press ) to
select a further reference value. The device automatically offers you the next undefined
reference value.
It is recommended to enter a maximum of two or three reference values for the linear
range of the vessel and to use the others for the non-linear portion
If you enter a second volume value for the same level, the reference value saved earlier is
overwritten.
4.2.5.8.2: Enter table
Manual entry of a table
Here you can enter up to 50 reference values provided by the vessel manufacturer in any
order.
The first reference value is offered when you access the parameter. Enter the level as a
distance from the floor of the vessel in the units selected according to parameter 4.1.1
(parameter “Enter level” and the volume corresponding to the level (parameter “Enter
volume”).
The device then displays the selection “Enter table” again. Access again to enter a
further reference value. The device automatically offers you the next undefined reference
value.
It is recommendable to enter a maximum of two or three reference values for the linear
range of the vessel and to use the others for the non-linear part.
If you enter a second volume value for the same level, the reference value saved earlier is
overwritten.

Parameters (HART)
4.2.5.8.3: Show table
Display table
Here you can display the entered reference values sorted on levels. In the second line,
the level corresponding to the first reference value appears first and then the
corresponding volume value when you switch further. Each switching accesses a further
reference value.
4.2.5.8.4: Clear table
Delete table
If you access the “all” selection in this parameter, the entire saved table is deleted. You
can delete individual reference values with the selection “1st”, “2nd” etc. which were
displayed in parameter 4.2.5.8.3.
or
4.2.5.8: Calculate
Automatic calculation of a vessel characteristic is faster than manual entry by calibrating
or a table. However, the calculated vessel characteristic is not as accurate as a manually
calibrated characteristic – especially in the non-linear areas of the vessel in which errors
of ≤ 1 % may occur. As well, the necessary data which you can get from the design
documents of your vessel must still correspond to the real conditions.
The 4.2.5.8: Calculate parameter requires the following parameters:

Parameters (HART)
In the “Hold...” parameters, the device outputs the last valid value until the set time has
run out or the fault has been eliminated. If the fault persists after the set time runs out,
the analog output switches to an error signal of 3.6 mA.
4.4 Digital Output
4.4.1: parameter DO (F = Alarm)
Assignment of the digital output
Here you can select whether the digital output supplies the upper or lower limit value of
level or volume or an alarm (device error, measurement error; see parameter 3.1) to the
control system. If you select the “No function” option, the digital output is switched off.
Selection of a limit value enables parameter 4.4.3.
4.4.2: Error Level (F = D: Error Signal)
Level for the error signal to alarm in Analog or Digital output
When D is selected, all errors are displayed. When D+F is selected, there is special
handling for failsafe. When D+F+W is selected, there is special handling for warnings.
