a clarification of the level of caution to be observed.

FCC and IC Conformity

US Installations only: Federal Communications Commission (FCC)

rules

Canadian Installations only: Industry Canada (IC) rules

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.

Notes:

• This device shall be installed and operated in a completely enclosed container to prevent

RF emission, which otherwise can interfere with aeronautical navigation. Installation

shall be done by trained installers, in strict compliance with the manufacturer’s

instructions.

• The use of this device is on a ’no-protection non-interference’ basis.

- The user shall accept operations of high powered radar in the same frequency band,

which may interfere with or damage this device.

- The user is responsible for removing, at the user’s expense, any device found to

interfere with primary licensing operations.

The Manual

SITRANS LR460 supports HART communication protocol, or PROFIBUS PA, and SIMATIC PDM

software, and this manual is in 3 parts:

•

SITRANS LR460 (HART/PROFIBUS PA)

on page 3: information for both HART/

PROFIBUS PA models, including:

• power, approvals, installation, connecting, programming, activating, quick start via

handheld programmer, communications via HART or PROFIBUS PA, quick start via

SIMATIC PDM

•

Hazardous area installations

•

SITRANS LR460 PROFIBUS PA wiring

on page 8

SITRANS LR460 (HART/PROFIBUS PA)

The SITRANS LR460 is a 4-wire 24 GHz FMCW radar level transmitter with extremely high

signal-to-noise ratio and advanced signal processing for continuous monitoring of solids up to

100 m (328 ft). It is ideal for measurement in extreme dust. The Easy Aimer design makes it

easy to install the device and orient the signal towards the material angle of repose. The high

frequency signal creates a narrow emission cone, which makes the LR460 quite insensitive to

vessel interferences.

Specifications

For a complete listing, see the SITRANS LR460 Instruction Manual, available from the product

page of our website at: https://pia.khe.siemens.com/index.asp?Nr=14655. For Approvals

WARNING: SITRANS LR460 is to be used only in the manner outlined in this

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

Installation shall only be performed by qualified personnel and in

accordance with local governing regulations.

Notes:

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

302372.

• Refer to device nameplate for approval information.

• Use appropriate conduit and conduit fittings or cable glands, to maintain IP or NEMA

rating.

• Observe maximum permissible ambient and process temperatures.

• For US and Canadian installations, see FCC and IC Conformity on page 2.

Notes:

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

programmer.

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

• Provide a sun shield if the device is mounted in direct sunlight.

Key considerations

• Nozzle design and nozzle location are critical to a successful application.

• Avoid reflective interference from vessel walls and obstructions by following the

guidelines below.

Nozzle design

Nozzle location

• Locate antenna at least 1 meter away from

side wall.

• Keep emission cone free of interference

from ladders, pipes, I-beams or filling

streams.

• Make allowance for beam spread to avoid

interference with the emission cone.

Device orientation

Align the antenna so that the radar cone is

perpendicular to the surface of the monitored

material, if possible.

Easy Aimer Installation

1. Holding the electronics enclosure firmly,

loosen the Easy Aimer ball locking bolts and

gently reposition the enclosure (see

Nozzle

design

above).

2. Direct SITRANS LR460 so the horn antenna

is pointed at an angle perpendicular to the material surface, if possible. (As a guide, aim

the beam at a point approximately 2/3 of the way across the tank diameter.)

3. When the desired position is reached, re-tighten the 5 bolts to 15-23 N m (11 to 17 Lbf-ft).

Note: When the Easy Aimer ball is loosened,

the device is free to tilt to a maximum of 30°.

min. clearance

10 mm (4")

• Bottom edge of horn must project from nozzle.

• Nozzle must have adequate clearance to allow LR460 to be positioned at an angle (see

below).

Wiring

Connecting SITRANS LR460

1. Release the cover lock on the enclosure with a 3 mm Allen key and unscrew the cover.

(Use a screwdriver for extra leverage, if required.)

2. Loosen the cable gland and push the power cable through until it reaches the terminal

strip.

3. Go to

SITRANS LR460 HART wiring

on page 7 or

SITRANS LR460 PROFIBUS PA wiring

on page 8 for next steps.

WARNINGS:

• Turn off power to the device before removing the cover in a hazardous area.

• All field wiring for AC models must have insulation suitable for at least 250 V.

• The DC input terminals shall be supplied from a source that provides electrical

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

requirements of IEC 61010-1.

• The equipment shall be protected by a fuse or circuit breaker of up to 16 A in the

building installation.

• A circuit breaker or switch in the building installation, marked as the disconnect

switch, shall be in close proximity to the equipment and within easy reach of the

operator.

• To avoid short-circuits, do not connect a load resistance with bare wires inside the

connection box.

Notes:

• AC and DC input circuits: min. 14 AWG (2.5 sq. mm) copper wire.

• Lay power cables separately from communication wiring.

• Recommended torque on terminal clamping screws: 0.5 to 0.6 N m (0.37 to 0.44 Lbf-ft).

Connecting HART

4. Connect the earth conductor of the power supply to

the earth terminal on the metal bracket inside

the enclosure. Adjust the cable length so that the

earth conductor would be last to disconnect if cable

is pulled.

5. Tighten the cable gland and check the strain relief

(pull and turn).

Note: LR460 HART requires no power from the 4-20 mA loop.

6. Replace the enclosure cover and hand tighten it. The sealing ring must be clean and

undamaged.

7. Tighten the screw on the cover lock.

8. Connect the external earth terminal located between the cable glands to a ground

connection at your vessel. Use a cable with a cross-section of 2.5 mm2or greater.

9. Return to

Power Demands

To determine how many devices can be connected to a bus line, calculate the combined

maximum current consumption of all the connected devices: 10.5 mA for SITRANS LR460.

Allow a current reserve for safety.

Bus Termination

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.

Install in accordance with

PROFIBUS PA User and Installation Guidelines

(order number 2.092),

available from www.profibus.com.

Note: PROFIBUS PA is not polarity-sensitive.
