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.

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
Device orientation 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).

SITRANS LR460 HART wiring
(continued from Connecting SITRANS LR460 on page 6)
Install in accordance with
Wiring and Installation in the HART Application Guide (order number
HCF_LIT-34), available from: http://www.hartcomm.org/technical/doclist.html.
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.

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.

Programming SITRANS LR460
To set up SITRANS LR460 for a simple application requires only the following settings:
• select application type (silo construction)
• select operation mode: level, distance or space
• set speed of response
• set high and low calibration points
A Quick Start Wizard groups together all the settings you need. There are two ways to access
the wizard:
•
Quick Start Wizard via the handheld programmer on page 10
•
Quick Start Wizard via SIMATIC PDM on page 13
Activating SITRANS LR460
Power up the instrument. SITRANS LR460 automatically starts up in RUN mode, and detects
the distance to the material level referenced from the sensor flange face. The LCD displays the
measurement and the default unit is meters. System status is displayed on the LCD, or on a
remote communications terminal.
RUN mode display
Quick Start Wizard via the handheld programmer
The Quick Start menu appears as soon as you activate PROGRAM mode.
Note: SITRANS LR460 only supports SIMATIC PDM version 6.0 with SP2 HF1 (or higher).
Notes:
• Keep infrared devices such as laptops, cell phones, and PDAs, away from
SITRANS LR460 to prevent inadvertent operation.
• Frequently switching the device off and on causes wear of the electronics. For details,
see the full manual.
Notes:
• The wizard is a complete package and the settings are inter-related.
• Do not use the Quick Start Wizard to modify individual parameters. See the full manual
for detailed instructions.
• Changes apply only after you select YES in parameter 1.8 (APPLY?).
