1Notes on use
You have various options for accessing the descriptions of instrument functions or how to enter
parameters.
1.1 Using the table of contents to locate a function description
All the functions are listed in the table of contents sorted by function group (e.g. basic setup,
safety settings, etc.). You can access a more detailed description of a function by using a page reference / link.
The table of contents is on ä 3.
1.2 Using the graphic of the function menu to locate a
function description
This guides you step by step from the highest level, the function groups, to the exact function
description you require.
All the available function groups and instrument functions are listed in the table ( ä 13). Select
your required function group or function. You can access an exact description of the function group
or function by using a page reference.
1.3 Using the index of the function menu to locate a
function description
To simplify navigation within the function menu, each function has a position which is shown in
the display. You can access each function via a page reference in the function menu index ( ä 91)
which lists all the function names alphabetically and numerically.

1.4 General structure of the operating menu
The operating menu is made up of two levels:
• Function groups (00, 01, 03, …, 0C, 0D):
The individual operating Selection of the instrument are split up roughly into different function
groups. The function groups that are available include, e.g.: "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 parameterisation of the instrument. Numerical values can be entered here and parameters can
be selected and saved. The available functions of the “basic setup (00)” function group include,
e.g.: "tank shape (002)",
"medium property (003)", "process cond. (004)", "empty calibr. (005)", etc.
If, for example, the application of the instrument is to be changed, carry out the following procedure:
1. Select the “basic setup (00)” function group.
2. Select the "tank shape (002)" function (where the existing tank shape is selected).
1.4.1 Identifying the functions
For simple orientation within the function menus ( ä 13), for each function a position is shown
on the display.

to min. level
1 Function group
2 Function
The first two digits identify the function group:
•basic setup 00
• safety settings 01
• temperature 03
…
The third digit numbers the individual functions within the function group:
•basic setup 00 • tank shape 002
• medium property 003
• process cond. 004
…
Hereafter the position is always given in brackets (e.g. "tank shape" (002)) after the described
function.

The following table describes the symbols that appear on the liquid crystal display:
Symbols Meaning
ALARM_SYMBOL
This alarm symbol appears when the instrument is in an alarm state. If the symbol flashes, this indicates
a warning.
LOCK_SYMBOL
This lock symbol appears when the instrument is locked,i.e. if no input is possible.
COM_SYMBOL
This communication symbol appears when a data transmission via e.g. HART, PFOFIBUS-PA or FOUNDATION Fieldbus is in progress.
SIMULATION_SWITCH_ENABLE
*
This communication symbol appears when simulation in FF is enabled via the DIP switch.

3.5 Function "empty calibr." (005)
This function is used to enter the distance from the sensor membrane (reference point of the measurement) to the minimum level (=zero).

E: empty calibration
Caution!
For dish bottoms or conical outlets, the zero point should be no lower than the point at which the
radar beam hits the bottom of the tank.
3.6 Function "blocking dist." (059)
In this function the blocking distance is displayed. Level echoes within the blocking distance can
not be detected by the Prosonic M. Make sure that the maximum level will never run into the blocking distance.

3.7 Function "full calibr." (006)
This function is used to enter the distance from the minimum level to the maximum level (=span).
"
F: full calibration (span); BD: blocking distance; SD: safety distance
Caution!
The maximum level may not project into the blocking distance (BD). If the blocking distance is compromised, it may cause device malfunction.
After basic calibration, enter a safety distance (SD) in the "safety distance" (015) function. If the
level is within this safety distance, the Prosonic M signals a warning or an alarm, depending on your
selection in the "in safety distance" (016) function.
3.8 Display (008)
The distance measured from the sensor membrane to the product surface and the level calculated
with the aid of the empty calibration are displayed. Check whether the values correspond to the
actual level or the actual distance. The following cases can occur:
• Distance correct – level correct -> continue with the next function, "check distance" (051)
• Distance correct – level incorrect -> Check "empty calibr." (005)
• Distance incorrect – level incorrect -> continue with the next function, "check distance" (051)

3.9 Function "check distance" (051)
This function triggers the mapping of interference echoes. To do so, the measured distance must be
compared with the actual distance to the product surface. The following options are available for
selection:
Selection:
•distance = ok
• dist. too small
• dist. too big
• dist. unknown
• manual
"
distance = ok
• mapping is carried out up to the currently measured echo
• The range to be suppressed is suggested in the "range of mapping (052)" function
Anyway, it is wise to carry out a mapping even in this case.
dist. too small
• At the moment, an interference is being evaluated
• Therefore, a mapping is carried out including the presently measured echoes
• The range to be suppressed is suggested in the "range of mapping (052)" function
dist. too big
• This error cannot be remedied by interference echo mapping
• Check the application parameters (002), (003), (004) and "empty calibr." (005)
dist. unknown
If the actual distance is not known, no mapping can be carried out.
manual
A mapping is also possible by manual entry of the range to be suppressed. This entry is made in the
"range of mapping (052)" function.
Caution!
The range of mapping must end 0.5 m (1.6 ft) before the echo of the actual level. For an empty tank,
do not enter E, but E – 0.5 m (1.6 ft).

3.10 Function "range of mapping" (052)
This function displays the suggested range of mapping. The reference point is always the sensor
membrane. This value can be edited by the operator.
For manual mapping, the default value is: 0 m.
3.11 Funktion "start mapping" (053)
This function is used to start the interference echo mapping up to the distance given in "range of
mapping" (052).
!
Selection:
• off: no mapping is carried out
• on: mapping is started
Note!
If a mapping already exists, it is overwriten up to the distance specified in
"range of mapping" (052). Beyond this value the existing mapping remains unchanged.

The distance measured from the reference point to the product surface and the level calculated with
the aid of the empty alignment are displayed again. Check whether the values correspond to the
actual level or the actual distance. The following cases can occur:
• Distance correct – level correct -> basic setup completed
• Distance incorrect – level incorrect -> a further interference echo mapping must be carried out
• Distance correct – level incorrect -> check "empty calibr." (005)
"check distance"(051).

Note!
After the basic setup, an evaluation of the measurement with the aid of the envelope curve
("display" (09) function group) is recommended.
