2. Parameterisation of the MWF electronic
2.1 General information
1. The MWF has been completely parametrised corresponding to your requirements ex works.
If the adaption of parameters is required, you should change only these parameters.
2. You find a sheet with all factory settings for the measuring parameters in the appendix of the
supplied operation manual of the MWF.
3. All necessary changes can be executed in the register Basic configuration.
4. In order to change the value of a parameter, please insert the requested value in the orange colored
field in the column variable.
With a click on SEND this value will be sent to the MWF electronic.
After a short time „ok“ is shown in the field status.
The new value has been stored in the MWF electronic. (The previous value has been overwritten)
5. In order to secure your changes please store the Excel-file on the connected PC.
With it the changed parameters can be checked again at any time or the Excel-file can be sent to
MOLLET for support.
6. During the process of parameterisation you can use the display on the MWF-HART-D2 modem for
monitoring the current output (4 –20 mA). This is done by pressing the red button for switching on
the display. After that you can read the actual measured value (filling level).
2.2 Parameterisation
Line 2 to 5 Setting of measuring range [M]
This is where the lower and upper measuring limits are parameterised. The values correspond to the
length at the probe in mm, measured from the reference point [R].
1. Insert in line 2 the value for the lower measuring limit [uMG] 4 mA.
2. Insert in line 3 the value for the upper measuring limit [oMG] 20 mA.
Line 6 and 7 No input
These values are for factory setting only. Please don´t do any changes!
Line 8 to 13 Setting of switching output
This is where the switching output is parameterised.
The switch-on and switch-off points of the switching output can be set at different positions within the
measuring range [M] (switching hysteresis) by setting different values for lower and upper switch points.
By using the same value for lower and upper switch points the least switching hysteresis is 3mm of the
probe length.
1. Insert in line 8 the function of the switching output. The factory setting NC can be change to NO by
setting the value „1“.
2. Insert in line 10 the value of the lower point of the switching output [uSA] and in line 12 the value of
the upper point of the switching output [oSA].
The values correspond to the length at the probe in mm, measured from the reference point [R].

Line 14 and 15 Setting of upper dead band [TB]
Dependent on the installation situation of the MWF signal disturbances could occur in the upper area of
the measuring probe (e.g. caused by a narrow nozzles). In order to suppress these disturbances, an
upper dead band can be determined. Within the entered length, starting from the reference point [R], the
measuring probe detects no signal.
1. Read in line 5 the value for the upper measuring limit [oMG] 20 mA.
2. Insert in line 14 the requested value for the upper dead band [TB]. This has to be less than the
value for the upper measuring limit from line 5 but more than the length of the nozzle.
Line 16 and 17 Adjustment of the sensitivity
Depending on bulk solids characteristics the sensitivity of the MWF has potentially to be adjusted. This
can be done by changing the so-called amplitude threshold.
1. Insert in line 16 a new value. Change the value in steps by 10 until you get a stable signal. The
lower the value for the amplitude threshold, the higher the sensitivity.
Examples for wrong adjusted sensitivity:
- In case of an instable measuring value the MWF is too sensitive and the amplitude threshold has to be
increased.
- In case of no signal in a filled-up silo the MWF is too insensitive and the amplitude threshold has to be
decreased.
Line 18 and 19 Setting of noise filter
The noise filter suppresses external disturbances, e.g. caused by large electric motors.
By activating the function „noise filter“, the function “disturbance signal suppression” (line 20) is
deactivated at the same time.
1. Insert in line 18 the value „1“ for activating the function „noise filter“.
Line 20 and 22 Setting of disturbance signal suppression
Installations (e.g. strut, ladder or measuring devices that cause an echo) near the probe could disturb the
measurement and deliver false signals that not correlate with the filling level. The disturbance signal
suppression serves to detect, buffer and eliminate these disturbance signals.
Attention!!! In order to perform a disturbance signal, scan the MWF must be mounted at the final position
prior to this and no bulk material / liquids may reside in the scan area (5,500 mm from top).
1. Insert in line 20 the value „01“ for activating the disturbance signal suppression. The disturbance
signal suppression has to be activated before a disturbance signal scan and elimination can be
done.
Start the disturbance signal scan with a click on START in line 22 und wait for the indication „ok“ in the
field status.
This can last up to one minute.
2. Insert in line 20 the value „00“ for deactivating the disturbance signal suppression.

Line 23 and 24 No input
Type of probe has to be „1“. Please don´t do any changes!
Line 25 and 26 Adjustment of probe length [L]
If the probe has been shortened or another probe with a different rope length has been mounted, the
probe length [L] has to be adjusted.
1. Insert in line 25 the value of the probe length [L] in mm, measured from the reference point [R].
Attention!!! After shortening the probe, it could be necessary to adapt the value for the lower
measuring limit in line 2 as well.
Line 27 Reset to MOLLET factory settings
Click on START in line 27 and the MWF will be reset to MOLLET factory settings.
All individual parameter settings will be overwritten with the primary MOLLET factory settings.
Line 28 Measuring of filling level
Click on START in line 28 and the actual filling level will be scanned. The scanned value corresponds to
the length at the probe in mm, measured from the reference point [R].
Line 31 and 32 Recording of signal image
1. Insert in line 32, in the lower, orange colored field the value of the probe length [L] in mm + 1000
mm rounded up to x000 and click on ADJUST.
Example: probe length 8600 mm, please insert value 10000.
2. Click on START in line 31 and the recording of the signal image will be started. The duration of the
recording is dependent on the probe length and can last up to 4 minutes.
3. Recording of signal image is finished as soon as „ok“ is permanent shown in the field status. Now
the signal image can be viewed in the register Signal.

4.3 Signal image with weak signal without indication of filling level.
A weak signal is indicated at approx. 1850mm, but no filling level is indicated or the filling level indication
varies.
There are two potential reasons for such a situation:
Reason 1: The signal is generated by a disturbing installation in an empty silo.
Action: Step back to register Basic configuration and follow the instructions in
chapter “Line 20 and 22 –Setting of disturbance signal suppression“.
Reason 2: The signal is generated by the bulk solids surface, but the value for the parameter
amplitude threshold is too high.
Action: Step back to register Basic configuration and follow the instructions in
chapter “Line 16 and 17 - Adjustment of the sensitivity “.
