WARNINGS:

• Never attempt to loosen, remove, or disassemble process connection or

instrument housing while vessel contents are under pressure.

• The user is responsible for the selection of bolting and gasket materials which

will fall within the limits of the flange and its intended use and which are suitable
for the service conditions.

• Improper installation may result in loss of process pressure.

Notes:

• The process connection tag shall remain with the process pressure boundary assembly

In the event the instrument package is replaced, the process connection tag shall be
transferred to the replacement unit.

•

SITRANS LR250 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.

The process pressure boundary assembly comprises the components that act as a barrier against

pressure loss from the process vessel: that is, the combination of process connection body and

emitter, but normally excluding the electrical enclosure.

Pressure Equipment Directive, PED, 97/23/EC

Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts

have no pressure-bearing housing of their own, and therefore do not come under the Pressure

Equipment Directive as pressure or safety accessories (see EU Commission Guideline 1/8 and

1/20).

Installation

Nozzle design

• The end of the antenna must protrude a minimum of 10 mm (0.4”) to avoid false echoes

being reflected from the nozzle.

• Minimum recommended nozzle diameter for the threaded PVDF antenna is 51 mm (2").
• An antenna extension (100 mm/ 3.93") is available for any version except the threaded

PVDF antenna.

WARNINGS:

• Installation shall be performed only by qualified personnel and in

accordance with local governing regulations.

• Handle the device using the enclosure, not the antenna or the process

connection tag, to avoid damage.

• Take special care when handling the threaded PVDF antenna. Any damage

to the antenna surface, particularly to the tip, could affect performance.

• Materials of construction are chosen based on their chemical compatibility

(or inertness) for general purposes. For exposure to specific environments,
check with chemical compatibility charts before installing.

Notes:

• For European Union and member countries, installation must be according to ETSI EN

302372.

• Refer to the device nameplate for approval information.
• The serial numbers stamped in each process connection body provide a unique

identification number indicating date of manufacture.
Example: MMDDYY – XXX (where MM = month, DD = day, YY = year, and XXX= sequential

unit produced)

• Further markings (space permitting) indicate flange configuration, size, pressure class,

material, and material heat code.

Nozzle location

Avoid central locations on tall, narrow vessels.

Environment

• Provide an environment suitable to the housing

rating and materials of construction.

• Provide a sunshield if the device will be mounted

in direct sunlight.

Beam angle

• Beam angle is the width of the cone

where the energy density is half of the
peak energy density.

• Peak energy density is directly in front

of and in line with the antenna.

• Signal is transmitted outside the beam

angle; therefore false targets may be
detected.

Emission Cone

• Keep emission cone free of interference

from ladders, pipes, I-beams or filling
streams.

Access for programming

• Provide easy access for viewing the display and programming via the handheld

programmer

Mounting instructions

Threaded Versions

Before inserting the instrument into its mounting connection, check to ensure the threads
are matching to avoid damaging them.

2) Simply screw the instrument into the process connection, and hand tighten, or use a

wrench. For pressure applications see Warning note above.

Flanged Versions

WARNING: For pressure applications use PTFE tape or other appropriate thread
sealing compound and tighten the process connection beyond hand-tight. The
maximum recommended torque is 40 N-m (30 ft.lbs.)

Note:

• There is no limit to the number of times an instrument can be rotated without damage.
• When mounting, orient the front or back of the instrument towards the closest wall.
• Do not rotate the enclosure after programming and vessel calibration, otherwise an error

may occur, caused by a polarity shift of the transmit pulse.

WARNING: The user is responsible for the selection of bolting and gasket materials
which will fall within the limits of the flange and its intended use, and which are
suitable for the service conditions.

Entity Concept:

The Entity Concept allows interconnection of Intrinsically Safe apparatus to associated

apparatus not specifically examined in such combination. The criteria for interconnection is

that the voltage and current which Intrinsically Safe apparatus can receive and remain

Intrinsically Safe, considering faults, must be equal to or greater than the output voltage (Uo)

and output current (Io) levels which can be delivered by the associated apparatus, considering

faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and

Inductance (Li) of the Intrinsically Safe apparatus, including interconnecting wiring, must be

equal to or less than the capacitance and inductance which can be safely connected to

associated apparatus.

FISCO Concept

Under the FISCO evaluation concept, SITRANS LR250 has the following characteristics:

The FISCO Concept allows interconnection of Intrinsically Safe apparatus to associated

apparatus not specifically examined in such combination. The criteria for interconnection is

that the voltage (Ui or Vmax), the current (Ii, or Imax) and the power (Pi, or Pmax) which

Intrinsically Safe apparatus can receive and remain Intrinsically Safe, considering faults, must

be equal to or greater than the voltage (Uo or Voc or Vi), the current (lo or Isc or li), and the

power (Po or Pmax) levels which can be delivered by the associated apparatus, considering

faults and applicable factors. In addition, the maximum unprotected capacitance (Ci) and

inductance (Li) of each apparatus (other than the termination) connected to the fieldbus must

be less than or equal to 5 nF and 10

H respectively.

In each segment only one active device, normally the associated apparatus, is allowed to

provide the necessary energy for the fieldbus system. The allowed voltage Uo (or Voc or Vt) of

the associated apparatus is limited to the range of 14V dc to 24V dc. All other equipment

connected to the bus cable has to be passive, meaning that they are not allowed to provide

energy to the system, except for a leakage current of 50

A for each connected device.

Separately powered equipment needs a galvanic isolation to assure that the Intrinsically Safe

fieldbus circuit remains passive.

2.Non-Sparking/Energy Limited wiring

• Approved dust-tight and water-tight conduit seals are required for outdoor NEMA 4X /

Programming SITRANS LR250

A Quick Start Wizard provides an easy step-by-step guide to help you configure the instrument

for a simple application.

• See

Quick Start Wizard via the handheld programmer

on page 19.

• See

Quick Start Wizard via AMS Device Manager

on page 23.

Settings can be modified locally via the Local User Interface (see

Accessing parameters via

the handheld programmer

on page 16) or remotely via AMS Device Manager. The Local User

Interface (LUI) consists of an LCD display and a handheld programmer.

Activating SITRANS LR250

Out of the box, SITRANS LR250 will not begin measurements, and all blocks will be Out of

Service until the instrument has been configured via the local user interface (LUI), or a remote

configuration tool.
Follow these steps to configure the instrument via the LUI:

• Power up the instrument
• The LCD at startup will show LANGUAGE. Edit or cancel this selection. When complete,

the instrument will show QUICK START.

• Complete the Quick Start Wizard (see

Quick Start Wizard via the handheld programmer

on page 19). Completing the Quick Start Wizard or writing any parameter via the LUI
causes the instrument to begin measuring.

• The Resource Block (RES) and Level Transducer Block (LTB) will move to Automatic

mode.

• AIFB 1 and AIFB 2 will remain Out of Service (as displayed on the LCD). These blocks can

only be configured and scheduled using a network configuration tool. For more details,
see System Integration in manual
