2.1 Incoming acceptance, transport, storage
2.1.1 Incoming acceptance
Check the packing and contents for any signs of damage. Check the shipment, make sure
nothing is missing and that the scope of supply matches your order.
2.1.2 Transport
"Caution!
Follow the safety instructions and transport conditions for instrument of more than 18 kg.
Do not lift the measuring instrument by its probe rod in order to transport it.
2.1.3 Storage
Pack the measuring instrument so that is protected against impacts for storage and transport. The
original packing material provides the optimum protection for this.
The permissible storage temperature is -40 °C ... +80 °C.

2.2 Installation
2.2.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• 4 mm Allen wrench for turning the housing.
2.2.2 Minimum distance between the probe and the tank wall
Any distance from the wall is allowed as long as the probe does not come into contact with the
tank wall.
!Note!
• When installing in plastic tanks, there should be no metal parts or movement of people outside
the tank at a distance of 300mm from the probe.
• Fouling or high-viscosity media should not create bridges to the wall.
2.2.3 Type of probe installation
• When installing in plastic tanks, the nozzle must have at least DN50/2". The appropriate
flange must be used as the process connection.
• For nozzles up to 450 mm high, select the length of the centering rod appropriate for the
nozzle height when using rope probes.
• Use spring washers (1) (see Figure).
!Note!
It is recommended to retighten the securing screws at regular intervals, depending on the
process temperature and pressure. Recommended torque: 60 to 100 Nm.
• After mounting, the housing can be turned 350° to make it easier to access the display and
the connection compartment.

2.2.4 Notes on special mounting situations
2.2.5 Special information on interface measurement
Installation in horizontal cylindrical, upright and underground tanks
• Use coax probes or rod probes in the bypass/stilling well. A segmented probe is available as a
special version for longer measuring ranges.
• Any distance from the wall is possible for coax probes or rod probes in the stilling well. In the
case of rod probes, it must be ensured that the probe does not come into contact with the wall.
L00-FMP4xIxx-17-00-00-xx-002.eps
Installation at an angle
• For mechanical reasons, rod probes should
be installed as vertically as possible.
• If installing at an angle, the probe length
must be limited, depending on the angle
of installation.
– Up to 1 m = 30°
– Up to 2 m = 10°
– Up to 4 m = 5°

!Note!
Rope and rod probes can only be freely installed in the tank under certain circumstances - please
contact your Endress+Hauser office.
Installation in stilling well or bypass
• A rod probe can be used for pipe diameters
bigger than 40 mm.
• Rod probe installation can take place up to
a diameter size of 100 mm. In the event of
larger diameters, a coax probe is
recommended.
• Welded joints that protrude up to approx.
5mm inwards do not affect the
measurement.
• The pipe may not exhibit any steps in
diameter.
• If a rod probe is used, the probe length
must be 100 mm longer than the lower
disposal.
• In the case of rod probes, it must be
ensured that the probe does not come into
contact with the wall. If necessary, use a
centering disk at the end of the probe.
!Note!
A plastic centering disk has to be used for
interface measurement (see Operating
Instruction on the CD-Rom).

Overvoltage protection
If the measuring device is used for the level measurement in flammable liquids which requires
the use of an overvoltage protection according to DIN EN 60079-14, standard for testprocedures
DIN IEC 60060-1 (10 kA, Puls 8/20 μs) it has to be ensured that
•
the measuring device with integrated overvoltage protection with gas discharge tubes within
the T12-enclosure is used, refer to product overview in the Operating instructions on CD-ROM
or
• this protection is achieved by the use of other appropriate measures (external protection
devices e.g. HAW262Z).
3.5 Screening/potential matching
• You achieve optimum screening against disturbances if the screening is connected on both
sides (in the cabinet and on the device). If you have to reckon with potential equalisation
currents in the plant, only earth screening on one side, preferably at the transmitter.
• When using in hazardous areas, you must observe the applicable regulations and the separate
Ex documentation.
3.6 Degree of protection
• with closed housing tested according to:
– IP68, NEMA6P (24 h at 1.83 m under water surface)
– IP66, NEMA4X
• with open housing: IP20, NEMA1 (also ingress protection of the display)
3.7 Post-connection check
After wiring the measuring instrument, perform the following checks:
• Is the terminal allocation correct (→ä11)?
• Is the cable gland tight?
• Is the housing cover screwed tight?
• If auxiliary power is available: Is the instrument ready for operation and is the liquid crystal
display visible?

Operation Levelflex M FMP41C 4...20 mA HART
14 Endress+Hauser
4Operation
4.1 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 options 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 properties"(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 properties"(002) function (where the existing tank shape is selected).
4.1.1 Identifying the functions
For simple orientation within the function menus, for each function a position is shown on the
display.

Commissioning Levelflex M FMP41C 4...20 mA HART
20 Endress+Hauser
The basic setup is sufficient for successful commissioning in most applications.
The Levelflex is precalibrated at the factory to the probe length ordered so that in most cases
only the application parameters that automatically adapt the device to the measuring conditions
need to be entered. For models with a current output, the factory adjustment for zero point and
span F is 4 mA and 20 mA, for digital outputs and the display module 0 % and 100 %.
A linearization function with a maximum of 32 points, which is based on a table entered
manually or semi-automatically, can be activated on site or via remote operation. This function
makes it possible to convert the level to volume and mass units and has a uniform effect on the
interface and the total level.
Complex measuring operations necessitate additional functions that the user can use to
customize the Levelflex as necessary to suit his specific requirements. The functions available to
do this are described in detail in BA366F – "Description of Device Functions" on the enclosed
CD-ROM.
Comply with the following instructions when configuring the functions in the
"basic setup"(00):
• Select the functions (see Operating Instruction on the CD-ROM).
• Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm
your data entries. Press Oor Sto select "YES" and press Fto confirm. The function is now
started.
• If you do not press a key during a configurable time period (→function group "Display (09)")
an automatic return is made to the home position (measured value display).
!Note!
• The device continues to measure while data entry is in progress, i.e. the current measured
values are output via the signal outputs in the normal way.
• If the envelope curve mode is active on the display, the measured values are updated in a
slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring
point has been optimized.
• If the power supply fails, all preset and configured values remain safely stored in the EEPROM.
"Caution!
All functions are described in detail, as is the overview of the operating menu itself, in
BA366F - "Description of Device Functions" on the enclosed CD-ROM.
