2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Are authorized by the plant owner/operator.
‣Are familiar with federal/national regulations.
‣Before starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the
application).
‣Follow instructions and comply with basic conditions.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Intended use
Application and media
The measuring device described in this manual is intended only for the level measurement
of bulk solids. Depending on the version ordered, the measuring device can also measure
potentially explosive, flammable, poisonous and oxidizing media.
If the limit values specified in the "Technical data" and the conditions listed in the
instructions and additional documentation are observed, the measuring device may be
used for the following measurements only:
‣Measured process variables: level
‣Calculable process variables: volume or mass in any shape of vessel (calculated from the
level by the linearization functionality)
To ensure that the measuring device remains in proper condition for the operation time:
‣Use the measuring device only for media to which the process-wetted materials have
an adequate level of resistance.
‣Observe the limit values in the "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-intended use.
Clarification of borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance
in verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability.
Residual risks
Due to heat transfer from the process as well as power loss in the electronics, the
temperature of the electronics housing and the assemblies contained therein (e.g. display
module, main electronics module and I/O electronics module) may rise up to 80 °C (176
°F). When in operation, the sensor may reach a temperature close to the medium
temperature.
Danger of burns from contact with surfaces!
‣In the event of high medium temperatures, ensure protection against contact to
prevent burns.

Spacing requirements when mounting
• Distance (A) between the vessel wall and rod and rope probes:
• For smooth metallic walls: > 50 mm (2 in)
• For plastic walls: > 300 mm (12 in) to metallic parts outside the vessel
• For concrete walls: > 500 mm (20 in), otherwise the permitted measuring range may
be reduced.
• Distance (B) between rod probes and internal fittings (3): > 300 mm (12 in)
• When using more than one Levelflex:
Minimum distance between the sensor axes: 100 mm (3.94 in)
• Distance (C) from the end of the probe to the bottom of the vessel:
• Rope probe: > 150 mm (6 in)
• Rod probe: > 10 mm (0.4 in)

Levelflex FMP56, FMP57 FOUNDATION Fieldbus Mounting
Endress+Hauser 19
Additional conditions
• When mounting outdoors, a weather protection cover (1) can be used to protect the
device against extreme weather conditions.
• In metallic vessels, preferably do not mount the probe in the center of the vessel (2), as
this would lead to increased interference echoes.
If a central mounting position cannot be avoided, it is essential to perform interference
echo suppression (mapping) after commissioning the device.
• Do not mount the probe in the filling curtain (3).
• Avoid buckling the rope probe during installation or operation (e.g. as a result of product
movement against silo wall) by selecting a suitable mounting location.
• The probe must be checked regularly for damage during operation.
In the case of freely suspended rope probes (probe end not fixed at the bottom), the
distance between the probe rope and internal fittings, which can change due to the
movement of the product, must never be less than 300 mm (12 in). Occasional
contact between the probe end weight and the cone of the vessel, however, does not
influence the measurement provided that the dielectric constant is at least DC = 1.8.
When the housing is mounted in a recess (e.g. in a concrete ceiling), observe a
minimum distance of 100 mm (4 in) between the cover of the connection
compartment/electronics compartment and the wall. Otherwise the connection
compartment/electronics compartment will not be accessible after installation.

Mounting with remote probe
The device version with a remote probe is suitable for applications with restricted
mounting space. In this case, the electronics housing is mounted at a separate position
from the probe.

• Product structure, feature 600 "Probe design":
• Version MB "Sensor remote, 3m cable"
• Version MC "Sensor remote, 6m cable"
• Version MD "Sensor remote, 9m cable"
• The connecting cable is included in the delivery with these versions.
Minimum bending radius: 100 mm (4 inch)
• The mounting bracket for the electronics housing is included in the delivery with these
versions. Mounting options:
• Wall mounting
• Mounting on DN32 to DN50 (1-1/4 to 2 inch) post or pipe
• The connection cable has one straight plug and one plug angled at 90°. Depending on
the local conditions the angled plug can be connected at the probe or at the electronics
housing.
The probe, electronics and connection cable are mutually compatible and bear a
common serial number. Only components with the same serial number may be
connected to one another.
