Contents of the operating instructions
This operating instrucitons contain all functions off the Prosonic M operating menu. All types of devices (FMU 40/41/
42/43) and all communication variants are considered.
Information on mounting, wiring, trouble shooting and maintenance can be found in the following documents which
are supplied together with the instrument:
•BA 237F/00/en (HART)
•BA 238F/00/en (PROFIBUS-PA)
•BA 239F/00/en (Foundation Fieldbus)
These documents can also be found on the second ToF Tool CD-ROM "Device Desriptions + Documentation"

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 Page 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 (see
Page 11). 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 (see page 79) 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 (see Page 11 ff.), for each function a
position is shown on the display.
The first two digits identify the function group:
The third digit numbers the individual functions within the function group:
Hereafter the position is always given in brackets (e.g. "tank shape"(002)) after the
described function.

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).
"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).
"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 distancemeasured 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,

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 (20") before the echo of the actual level. For an
empty tank, do not enter E, but E –0.5 m (20").
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.

3.12 Display (008)
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 "check distance"(051).
•Distance correct –level incorrect -> check "empty calibr."(005)
!Note!
After the basic setup, an evaluation of the measurement with the aid of the envelope
curve ("display"(09) function group) is recommended.
