Safety Guidelines

Warning notices must be observed to ensure personal safety as well as that of others, and to

protect the product and the connected equipment. These warning notices are accompanied by

a clarification of the level of caution to be observed.1

FCC Conformity

US Installations only: Federal Communications Commission (FCC) rules

SITRANS LR250

SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of

liquids and slurries in storage vessels including high pressure and high temperature, to a range

of 20 m (66ft). It is ideal for small vessels and low dielectric media.

The device consists of an electronic component coupled to a horn antenna and either a

threaded or flange type process connection.

SITRANS LR250 supports HART communication protocol, and SIMATIC PDM software. Signals

are processed using Process Intelligence.

WARNING: relates to a caution symbol on the product, and means that failure to

observe the necessary precautions can result in death, serious injury, and/or

considerable material damage.

WARNING1: means that failure to observe the necessary precautions can result

in death, serious injury, and/or considerable material damage.

Note: means important information about the product or that part of the operating manual.

1. This symbol is used when there is no corresponding caution symbol on the product.

WARNING: Changes or modifications not expressly approved by Siemens

Milltronics could void the user’s authority to operate the equipment.

Notes:

• This equipment has been tested and found to comply with the limits for a Class A digital

device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in a

commercial environment.

• This equipment generates, uses, and can radiate radio frequency energy and, if not

installed and used in accordance with the instruction manual, may cause harmful

interference to radio communications. Operation of this equipment in a residential area is

likely to cause harmful interference to radio communications, in which case the user will

be required to correct the interference at his own expense.

WARNING: SITRANS LR250 is to be used only in the manner outlined in this manual,

otherwise protection provided by the equipment may be impaired.

Note: Use appropriate conduit seals to maintain IP or NEMA rating.

WARNINGS:

• This product is designated as a Pressure Accessory per Directive 97 / 23 / EC, and

is not intended for use as a safety device.

• Do not attempt to loosen, remove, or disassemble process connection or

instrument housing while vessel contents are under pressure.

• Improper installation may result in loss of process pressure.

2. 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.

WARNINGS:

• Installation shall only be performed by qualified personnel and in

accordance with local governing regulations.

• 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.

• The Process Device Tag shall remain with the process pressure boundary assembly2. In

the event the device package is replaced, the Process Device 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.

Installation guidelines

• Provide easy access for viewing the display and programming via the hand programmer.

• Provide an environment suitable to the housing rating and materials of construction.

• Provide a sunshield if the device will be mounted in direct sunlight.

Nozzle design

• The end of the horn must protrude a minimum of

10 mm (0.4”) to avoid false echoes being reflected

from the nozzle.

• An antenna extension: (100 mm / 3.93") is

available.

Nozzle location

• Keep emission cone free of

interference from ladders, pipes,

I-beams or filling streams.

• Make allowance for the emission

code spreading, to avoid

interference with vessel walls or

obstructions. (Beam angle

depends on horn size.)

• Avoid central locations on tall,

narrow vessels, which can

generate false echoes

Note: Beam angle depends on horn

size.

Mounting instructions

Threaded Version

1. Before inserting the device into its mounting connection, check to ensure the threads are

matching to avoid damaging them.

2. Simply screw the device into the process connection, and hand tighten, or use a wrench.

A torque of 40 N m (30 ft.lbs) is recommended.

Flanged Version

Wiring

Power

Connecting SITRANS LR250

WARNING: For pressure applications, it will be necessary to use PTFE tape or other

appropriate thread sealing compound, and to tighten the process connection

beyond hand-tight.

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.

WARNINGS:

The DC input terminals shall be supplied from a source providing electrical

isolation between the input and output, in order to meet the applicable safety

requirements of IEC 61010-1.

All field wiring must have insulation suitable for rated voltages.

WARNINGS:

• Check the device nameplate and process device tag, to verify the approval rating.

• Use appropriate conduit seals to maintain IP or NEMA rating.

•Read

Instructions specific to hazardous area installations

on page 10.

Notes:

• For detailed wiring instructions, please refer to the full Instruction Manual.

• Use twisted pair cable: AWG 22 to 14 (0.34 mm2to 2.5 mm2).

• Separate cables and conduits may be required to conform to standard instrumentation

wiring practices, or electrical codes.

2. Strip the cable jacket for approximately 70 mm (2.75") from the end of the cable, and

thread the wires through the gland.

3. Connect the wires to the terminal as shown: the polarity is identified on the terminal

block.

4. Ground the device according to local regulations.

5. Tighten the gland to form a good seal.
