1 Notes on using this manual
There are various ways of getting to the device function you require or the parameters to be entered.
1.1 Using the table of contents to locate a function
description
All the functions are listed by function group (e.g. "Basic Setup", "Security Settings", etc.) in the table
of contents. The page reference/link shows you exactly where to find the detailed descriptions of
the functions in question.
The table of contents can be found on →ä4.
1.2 Using the graphic display of the function menus to
locate a function description
This step-by-step, top-down approach starts with the function groups, the highest level, and works
down through the matrix to the description of the function you need.
All the available function groups and functions of the device are listed in the table (→ä12). Select
the function group or a function needed for your particular application. The page reference/link
shows you exactly where to find the detailed description of the function group or function in
question.
1.3 Using the index of the function menu to locate a
function description
To ease orientation within the function menu, a position is shown on the display for each function.
The function menu index (→ä71) which lists the codes for all the functions in alphabetical or
numerical order takes you to the function in question via a page reference or link.

1.4 General structure of the operating menu
The operating menu is made up of two levels:
•Function groups (00, 01, … , 0C, 0D):
The individual operating options of the device are split up roughly into different function groups.
The function groups that are available include: "Basic Setup", "Safety Settings", "Output",
"Display", etc.
•Functions (001, 002, 003, …, 0D8, 0D9):
Each function group consists of one or more functions. The functions perform the actual operation
or configuration of the device. Numerical values can be entered here and parameters can be
selected and saved. The functions available for the "Basic Setup"(00) function group include:
"Tank Properties"(002), "Process Propert."(004), "Empty Calibration"(005), etc.
If, for example, the application of the device is to be changed, carry out the following procedure:
1. Select the "Basic Setup"(00) function group
2. Select the "Tank Properties"(002) function (where the tank level is selected).
1.4.1 Identifying the functions
To ease orientation within the function menus (See →ä12), a position is shown on the display for
each function.
The first two digits identify the function group:
The third digit numbers the individual functions within the function group:
In the following section, the position is always indicated in brackets (e.g."Tank Properties" (002))
after the function described.
• Basic Setup 00
• Safety Settings 01
• Length Adjustment 02

3.1 Function "Measured Value" (000)
This function displays the current measured value in the selected unit(see "Customer Unit"(042)
function). The number of digits after the decimal point can be selected in the "No. of
Decimals"(095) function.
The standard settings for PV and SV assignment are as follows:
PV corresponds to the interface layer; SV = total level
3.2 Function "Tank Properties" (002)
This function is used to select the tank properties.
Depending on the settings, the system searches for one (flooded) echo or 2 (partially filled) echoes.
Options:
• Partially Filled
• Flooded
Partially Filled
The system searches for 2 signals in the measuring range. The upper signal is assigned to the total
level and the lower signal to the level of the interface layer. The difference between the two levels
corresponds to the thickness of the upper phase.
Flooded
The biggest signal in the measuring range is evaluated. If the signal for the total level is within the
upper blocking distance, the signal detected corresponds to the level of the interface layer. If an echo
is not found, echo loss is detected.
!Note!
• If "Flooded" is selected, it is absolutely essential that the upper signal for the total level is within
the upper blocking distance so that it is not evaluated incorrectly. The setting for the upper
blocking distance is an integral part of the basic setup if "Flooded" is selected.
• A change in the total level when "Flooded" is selected impacts the accuracy.

3.3 Function "Process Propert." (004)
Use this function to adapt the device reaction to the filling speed in the tank. The setting influences
an intelligent filter and affects the total level and interface layer level in the same way.
Options:
• Standard
• Fast Change
•SlowChange
• Test: No Filter
3.4 Function "Empty Calibr." (005)
This function is used to enter the distance from the flange (reference point of the measurement) to
the minimum level (=zero).

Options: Standard Fast Change Slow Change Test: No Filter
Application: For all normal applications, bulk
solids and liquids with low to
medium filling speeds and
sufficiently large tanks.
Small tanks, primarily with
liquids, at high filling speeds.
Applications with severe surface
movement, e.g. caused by
agitator, primarily large tanks
with low to medium filling
speeds.
Shortest reaction time:
• For test purposes
• Measurement in small tanks
at high filling speeds, if "Fast

3.6 Function "Upper Block. Dist." (059)
For rod probes and for rope probes with lengths of up to 8 m, the upper blocking distance is preset to
0.1 m on delivery.

Note!
When installing in flooded bypasses, the blocking distance is used to map the total level echo. It may
have to be adjusted to suit local conditions.
Maximum measured error
Typical data under reference conditions:
DIN EN 61298-2, percentage values in relation to the span.
If the reference conditions are not met, the offset/zero point arising from the mounting situation
may be up to ±12 mm for rope and rod probes. This additional offset/zero point can be
compensated for by entering a correction (function "Offset" (057)) during commissioning.

Differing from this, the following measuring error is present in the vicinity of the level
(electronic version level and interface measurement):
If for rope probes the DC value is less than 7, then measurement is not possible in the area of the straining
weight (0 to 250 mm from end of probe; lower blocking distance).

The tables below divide the DK values by product group. However, it is not sufficient to assume a
typical value. For accurate interface measurement, it is necessary to determine the DK of the upper
medium (upper phase) as accurately as possible and enter the value in this function.
The DK of the upper medium must be known and constant. The DK can be determined via the DK
manual SD106F. If there is an interface of known thickness, the DK can also be calculated
automatically by FieldCare.
3.8 Display (008)
The measured distances from the reference point to the product level and the interface are shown.
Check whether the values correspond to the actual distances. The following cases can occur:
• Distances correct -> continue with group selection
• Distance to level incorrect -> empty tank/bypass and perform mapping over the entire probe
length.
• Distance to interface incorrect -> check entry for "Medium Prop." (003).
