6Installation and connection
Intended use
Information on mounting position
If the sensor is installed in the tank, the measurement signal will not be reliable in an area of
20 mm (35 mm) from the sealing edge (see dimensional drawing). This means that the 4 mA or
20 mA signal is located on the bottom weld seam of the measuring rod.
The continuous level sensor NSL-F is set to operate in aqueous media without requiring special
settings. In case of highly critical media or special tank contours (with inside fittings such as a
pipe), it may be necessary to adjust some parameters. The parameterization may be changed
using the PC-based MPI-200 programming adapter or the Simple User Interface. The setting
can either be set or changed directly on location or in the office in a dry simulation.
When setting the parameters, it must be ensured that the various authorization levels are en-
abled (see "Associated setup mode" column). The Monitor and Adjust levels are not required
for setting the NSL-F sensor. These levels can be individually protected with a password and
thus made available to specific users/service personnel. The software in both the PC/MPI-200
and Simple User Interface features a tree structure.

4...20-mA signal
•Filling level height for 4/20-mA signal
•"Dry run" warning signal
•"Failure" error signal
•“Underdrive/overdrive”signal limit
•"Underflow/overflow" error signal
•Signal simulation (3.95...20.05 mA)
Filling level measurement
•Filling level zero point/offset
•Filling level slope/gain
•Damping/filter
•Physical unit
A list of the parameters settings in the continuous level sensor is included with the delivery. These de-
fault parameter values, and the parameter values changed by the user, can be printed out using the MPI-
200 programming adapter software.
When making the settings, note the help texts in the MPI software. These contain additional useful
information on changing the selected parameter.
6.1 Setup using the MPI-200 programming adapter
The MPI-200 programming adapter is connected to the NSL-F continuous level sensor via the ex-
ternal MPI-200-F adapter piece. It must be ensured that the NSL-F continuous level sensor is per-
manently connected to the supply voltage while the parameters are being set.
Connection of the programming adapter MPI-200
1: Connection for M12 connector
(external power supply)
2: USB port for connecting
to a PC incl. power

7Installation of the „Large User Interface“ (LUI)
1. Remove the plastic cover (continue with step 4), or remove the puck with the mounted small dis-
play (continue with step 2)
2. Remove the small display
3. Install the puck in the sensor head
4. Mount the large display
Hot-plug function: The large display can be installed while the sensor is energized, but this requires the
usual precautionary measures when working with electronic components.
If the display is being installed while energized, it is necessary to press both buttons simultaneously
for > 10 s after the display is installed to activate the display.
7.1 Retrofitting the display if a display was not yet installed
After removing the plastic cover, the large display can be inserted in the head of the sensor. The tabs
(Fig. 2) must be inserted in the appropriate openings on the puck (Fig. 1). Then the display can be easily
pressed onto the puck. No wiring is required.
Note: After the Large User Interface is mounted, the sensor can only be operated on this display since
the display conceals the connector for the MPI-200 adapter. If operating the sensor using the program-
ming software is preferred, the display must be removed. Then the connector of the programming
adapter can be plugged in
Remove the plastic cover: To do so, bend the tabs
slightly inwards with a screwdriver to be able to
remove the cover easily.
fig. 1
fig. 2

NSL-F Series Operating Manual 13
Attention: The connector of the programming adapter (Fig. 3) must be connected in the correct direc-
tion the green spacer must face the cable exit (M12 connector or PG).
7.2 Retrofitting the display if a small display (SUI) was already installed
First the puck with the mounted display needs to be removed using the puck puller tool (Fig. 1). To do
so, detach the wires from the cable terminal. Then insert the five arms of the puck puller in the plastic
tabs of the puck (Fig. 2).
Push the puck puller all the way into the sensor head and push
the disk as far as possible toward the sensor head so that the
arms of the puck puller firmly grasp the puck.
Pull the puck with the display out of the sensor housing and pull
the small display off of the puck.
Now the puck without the display can be properly positioned and installed back in the sensor head
and the wiring can be reconnected to the cable terminal. Then the large display can be mounted 
see "Retrofitting the display if a display was not yet installed".
7.3 Operating the large display
The large display (LUI) is operated in the same way as the small display (SUI). It is operated using two
operating buttons below the display:
After the sensor is started, the screen saver appears in which the process values of the sensor are
displayed one after the other. To reach the start page from here, press one of the two buttons briefly.
Further information on operating the display can be found in the quick start manual and in the operat-
ing manual for the modular sensors (ILM-4, NSL-F…).
