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 LR260

SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of

solids in storage vessels including extreme levels of dust and high temperatures, to a range of

30 m (98.4 ft).

The instrument consists of an electronic component coupled to a horn antenna with an

integral Easy Aimer and flange for quick and easy positioning. A dust cover or air purging are

available as options.

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 LR260 is to be used only in the manner outlined in this

manual, otherwise protection provided by the equipment may be impaired.

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

Pressure Application

Installation1

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.

• Optional antenna extension: 100 mm (3.93"),

200 mm (70.9"), 500 mm (19.69"), 1000 mm (39.4")2

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.

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 assembly1. In

the event the instrument package is replaced, the Process Device Tag shall be transferred

to the replacement unit.

• SITRANS LR260 units are hydrostatically tested, meeting or exceeding the requirements

of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment

Directive.

1. 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.

2. Extensions are not recommended for applications where there may be excessive visible vibration.

Please consult factory for more information.

Nozzle location

• Keep emission cone free of

interference from ladders, pipes,

I-beams or filling streams.

• Avoid central locations on tall,

narrow vessels.

• Align the antenna so that the

radar cone is perpendicular to the

surface of the monitored material,

if possible.

Note: Beam angle depends on horn

size.

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, meeting the applicable safety

requirements of IEC 61010-1.

All field wiring must have insulation suitable for rated voltages.

Connecting SITRANS LR260

1. Use a 2 mm Allen key to loosen the lid-lock set screw then using a screwdriver for

leverage if necessary, unscrew the cover.

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

thread the wires through the gland1.

3. Connect the wires to the terminal as shown (SITRANS LR260 is not polarity sensitive)

4. Ground the device according to local regulations.

5. Tighten the gland to form a good seal.

6. Close the lid and secure the locking ring before programming and calibration..

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

Wiring setup for hazardous area installations

on page 7.

Note:

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

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

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

wiring practices, or electrical codes.

1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.

Notes:

• PROFIBUS PA must be terminated at both extreme ends of the cable for it to work

properly.

• Please refer to the

PROFIBUS PA User and Installation Guidelines

(order number 2.092),

available from www.profibus.com, for information on installing PROFIBUS devices.
