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
A 4 mm Allen key is needed to turn the housing.
2.2.2 General instructions
Normally use rod probes. Rope probes are used for measuring ranges > 4 m and with restricted
ceiling clearance which does not allow the installation of rigid probes
Mounting location
• Do not mount the probe in the filling
curtain (2).
• Mount the probe at such a distance away
from the wall (B) that, in the event of
buildup on the wall, there is still a
minimum distance of 100 mm between
the probe and the buildup.
• Mount the probe as far away as possible
from internals.
• The minimum distance from the probe
end to the tank floor is 10 mm.
• If installing outdoors, it is recommended
that you use a weather protection cover
(1). See "Accessories" in Operating
Instruction on the CD-Rom.

!Note!
You must ensure that the probe does not come into contact with the container wall, container
bottom and tank internals.
2.2.3 Special instructions
When installing in tanks with agitator, observe the lateral loading capacity of rod probes:
• 10 Nm with 1.4435 / SS316L
• 16 Nm with Hasteloy C22 (auf Anfrage).
The formula for calculating the bending torque M impacting on the probe:
with
cw: Friction factor
ρ [kg/m3]: Density of the medium
v [m/s]: Velocity of the medium perpendicular to the probe rod
d [m]: Diameter of the probe rod (8 mm)
L [m]: Level
LN[m]: Probe length
Tank internals
• If the distance to the internals is < 300
mm, "mapping" must be carried out, and
the measurement capability may be
restricted.
• During operation, the probe must not
touch any internals within the measuring
range.
Optimization options
• Interference echo suppression:
measurement can be optimized by
electronically suppressing interference
echoes.

2.2.4 Notes on special installation situations
The probe must be mounted opposite the
agitator. If possible, check whether a
non-contact process, ultrasonic or
level-radar would be better suited,
particularly if the agitator generates large
mechanical loads on the probe
L00-FMP43xxx-17-00-00-xx-005
Installation at an angle
• For mechanical reasons, the probe should
be installed as vertically as possible.
• The maximum mounting angle is
– up to 1 m = 30°
– up to 2 m = 10°
– up to 4 m = 5°

Installation in plastic containers
Please note that the "guided level radar" measurement principle requires a metallic surface at the
process connection!
When installing rod or robe probes in plastic silos, whose silo cover is also made of plastic or silos
with wood cover, the probes must either be mounted in a ≤DN 50 / 2" metallic flange, or a
metal sheet with diameter ≥200 mm must be mounted under the screw-in piece.

2.2.5 Turn housing
After mounting, the housing can be turned 350° in order to simplify access to the display and
the terminal compartment. Proceed as follows to turn the housing to the required position:
• Undo the fixing screws (1)
• Turn the housing (2) in the required direction
• Tighten up the fixing screws (1).
L00-FMP4xxxx-17-00-00-en-028
2.3 Post-installation check
After the measuring instrument has been installed, perform the following checks:
• Is the measuring instrument damaged (visual check) ?
• Does the measuring instrument correspond to the measuring point specifications such as
process temperature/pressure, ambient temperature, measuring range, etc..?
• Are the measuring point number and labeling correct (visual check ?
• Is the measuring instrument adequately protected against rain and direct sunlight (see Chapter
"Accessories" in the Operating Instructions on the CD-ROM) ?

2.4 Cleaning of the probe
2.4.1 Cleaning of the probe in the tank
Installation close to tank wall
• By installing the probe close to the tank
wall, the cleaning effect is improved in
cases where a spray ball is used. The
cleaning jet is deflected against the tank
wall and onto the probe. This means that
those parts of the probe are cleaned which
would normally not be reached by the
spray ball jet. If the probe is positioned in
this way, only one spray ball is needed.
L00-FMP43xxx-17-00-00-xx-003
Installation in the center of the tank
• If the probe is mounted in the center of
the tank, it may be necessary to use a
second spray ball. The spray balls should
then be mounted to the left and right of
the probe.

The following values are the voltages across the terminals directly at the instrument:
• standard: 9V...32V
• Lift-off voltage: 9V
Current consumption
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).
3.7 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.
3.8 Degree of protection
• with closed housing tested according to:
– all housing: IP68, NEMA6P (24 h at 1.83 m under water surface); IP66, NEMA4X
– F23 housing: IP69K in combination with cable entries M20, G½ and NPT½
• with open housing: IP20, NEMA1 (also ingress protection of the display)

3.9 Post-connection check
After wiring the measuring instrument, perform the following checks:
• Is the terminal allocation correct (→ä15)?
• Is the cable gland tight?
• Is the FOUNDATION Fieldbus connector screwed 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 FMP43 with FOUNDATION Fieldbus
18 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.
