!Note!
These Operating Instructions describe how to install and commission the level transmitter.
All functions that are needed for regular measuring tasks are taken into account.
In addition, the silometer, for example, has many other functions for optimising the measuring point
and converting the measured value which do not form part of these Operating Instructions.
An overview of the configuration options at the FEI57C electronic insert is provided on

1 Safety instructions
1.1 Designated use
Liquicap M FMI51, FMI52 are compact, capacitance level transmitters for the continuous
measurement of conductive liquids.
1.2 Installation, commissioning and operation
Liquicap M is designed to meet state-of-the-art safety regulations and complies with the applicable
requirements and EC Directives. If used improperly or other than intended, the device can,
however, be a source of application-related danger, e.g. product overflow as a result of incorrect
installation or configuration. For this reason, installation, electrical connection,
commissioning,operation and maintenance of the measuring system must only be carried out by
trained technical personnel authorised to perform such work by the owner-operator.The technical
personnel must have read and understood these Operating Instructions and must follow the
instructions they contain. The device may only be repaired or modified if expressly permitted in the
Operating Instructions.
1.3 Operational safety
1.3.1 Ex area
When using the measuring system in Ex-areas, the appropriate national standards and regulations
have to be observed. Separate Ex documentation, which constitutes an integral part of this
documentation, is supplied with the device. The installation procedures, connection data and safety
instructions it contains must be observed.
• Make sure that the technical staff has adequate training.
• The special measuring and safety-related requirements for the measuring points must be
observed.

1.4 Notes on safety conventions and icons
To highlight safety-related or alternative processes, we have designed the following safety
instructions where every instruction is indicated by a corresponding pictogram.
Safety instructions
#
Warning!
Draws attention to activities or procedures that can result in serious injuries to persons, a safety risk
or the destruction of the device if not carried out properly.
"
Caution!
Draws attention to activities or procedures that can result in injuries to persons or the defective
operation of the device if not carried out properly.
!
Note!
Draws attention to activities or procedures that have an indirect effect on operation, or can trigger an
unforeseen device reaction if not carried out properly.
Type of protection
0
Explosion-protected equipment tested for type examination
If this sign can be found on the nameplate of the device, the device can be operated in hazardous
areas or non-hazardous areas in accordance with the approval
-
Hazardous area
This symbol in the drawings in these Operating Instructions indicates Ex-areas. Devices located in
Ex-areas, or cables for such devices, must have appropriate explosion protection.
.
Safe area (non-hazardous area)
This symbol in the drawings in these Operating Instructions indicates non-Ex areas. Devices in non-
hazardous areas must also be certified if connecting cables lead into hazardous areas.
Electrical symbols
%
Direct current
A terminal to which direct voltage is applied or through which the direct current flows.
&
Alternating current
A terminal to which alternating voltage (sine wave) is applied or through which the alternating
current flows.
)
Ground connection
A grounded terminal which, from a user's point of view, is grounded via a grounding system.
*
Protective earth connection
A terminal that has to be grounded before any other connections may be established.
+
Equipotential connection
A connection that has to be connected to the grounding system of the plant. This can be a potential
matching line or a star grounding system, depending on national or company codes of practice.
Immunity to temperature change of the connecting cables
Means that the connecting cables have to withstand a temperature of 85 °C at least.

3 Installation
3.1 Quick installation guide
L00-FMI5xxxx-17-06-xx-xx-001
1.) Screw in the device
2. a) Loose clamping screw that the housing can be alined easily.
2. b) Align the housing.
2. c) Tighten clamping screw (< 1 Nm) until the housing can no longer be rotated.
3.2 Incoming acceptance, transport, storage
3.2.1 Incoming acceptance
Check whether the packaging or content is damaged.
Check that the goods delivered are complete and compare the scope of delivery against the
information on your order.
3.2.2 Transporting to the measuring point
"Caution!
Observe safety instructions and transportation conditions for devices over 18 kg.
3.2.3 Storage
