NSL-F Series Operating Manual 3
Application/intended use
Continuous level monitoring in metallic vessels up to 3m in height
Ideal for highly adhesive and pasty media
Filling level measurement of foamy media
Hygienic use for float sensors
Generally for media with a conductivity of 5 µS/cm or higher (media with a lower conductivity re-
quire individual clarification regarding the tank contour, temperature, assembly, etc.)
Not suitable for explosive areas
Not suitable for safety-related unit parts (SIL)
1Conformity with standards
The basic safety and health requirements are met through fulfillment of
2014/30/EU Electromagnetic Compatibility
1935/2004/EU Consumer Goods Ordinance
Directive (EU) 10/2011 (articles in contact with food)
EN 61000-6-2:2005 (Interference Immunity)
EN 61000-6-4:2007 + A1:2011 (Interference Emissions)
2Safety instructions
These safety instructions must be followed to
Avoid endangering persons and the environment
Avoid damage to the sensors
Prevent faulty batches during production
The electrical connections may only be performed by persons with the necessary technical skills (e.g. cer-
tified electricians or persons with technical training in electrics) and by persons with the necessary au-
thorization from the operator.
The power supply and the control circuit inputs and outputs must be properly wired. The current state-of-
the-art of electrical connections must be adhered to. See also section 8 "Wiring diagram".
The following details must be noted in particular:
Safety instructions
Electrical connection data
1. All persons involved with the setup, commissioning, operation, service and maintenance of the sen-
sor must be suitably qualified.
2. This operating manual must be followed precisely. The operator must ensure that the personnel has
read and fully understood the operating manual.
3. All work must be performed with utmost care and may only be performed by authorized and trained
personnel. The regulations effective in the country of use regarding the opening and repair of the
devices must be adhered to.
4. The operating manual must be stored in the vicinity of the measurement equipment in an easily ac-
cessible location.
5. The sensor must be de-energized prior to alterations and maintenance.
6. The working area of the operator must offer enough space to minimize the risk of injury.
7. The technical data specified in the operating manual and on the type label must be adhered to.
Warranty coverage shall not be granted for any damage that can be attributed to improper execution of
work.

5Installation 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 set-
tings. 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 leve ls are enabled (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
“Underdriven/overdriven”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
Mounting position
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 u seful
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 external
MPI-200-F adapter piece. It must be ensured that the NSL-F continuous level sensor is permanently con-
nected 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
supply if not supplied externally
3: Connecting cable to
adapter for NSL-F
