SITRANS Probe LU (PROFIBUS PA)
SITRANS Probe LU is a 2-wire loop-powered, continuous level monitor that uses advanced
ultrasonic techniques. The instrument consists of an electronic component coupled to the
transducer and process connection.
The transducer is available in ETFE (ethylene-tetrafluoroethylene) or PVDF (polyvinylidene
fluoride), allowing SITRANS Probe LU to be used in a wide variety of industries and
applications using corrosive chemicals.
The ultrasonic transducer contains a temperature-sensing element to compensate for
temperature changes in the application.
Communication is via PROFIBUS PA. This device supports acyclic communications from both a
PROFIBUS Class I and Class II master. Signals are processed using Sonic Intelligence® which
has been field-proven in over 500,000 applications worldwide (ultrasonic and radar).
SITRANS Probe LU is available in three versions:
• General Purpose (non-hazardous)
• Intrinsically Safe (with suitable barrier)
• Non-Incendive (FM Class I, Div. 2)
Specifications
For a complete listing, see the SITRANS Probe LU (PROFIBUS PA) Instruction Manual. For
Approvals information, please refer to the device nameplate1.
WARNING: Changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate, radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving transducer.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a different circuit from the one to which the
receiver is connected.
• Consult an experienced radio/TV technician for help.
Note: This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based communications.

Recommendations
• Ambient temperature should be within –40 to +80 °C (–40 to +176 °F).
• 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.
• Keep the sound path perpendicular to the material surface.
Precautions
• Avoid proximity to high voltage or current wiring, high voltage or current contacts, and to
variable frequency motor speed controllers.
• Avoid interference to the sound path from obstructions or from the fill path.

WARNINGS:
• Installation shall only be performed by qualified personnel and in accordance with
local governing regulations.
• SITRANS Probe LU is to be used only in the manner outlined in this manual,
otherwise protection provided by the equipment may be impaired.
Note: Please refer to the device nameplate for approval information.

Mounting instructions
SITRANS Probe LU is available in three thread types: 2" NPT, 2" BSP, or PF2/G (BS EN ISO 228-1).
1. Before inserting SITRANS Probe LU into its mounting connection, ensure that the threads
are of the same type to avoid damaging them.
2. Simply screw SITRANS Probe LU into the process connection and hand tighten.
Wiring
Power1
Connecting SITRANS Probe LU (PROFIBUS PA)
1. Strip the cable jacket for approximately
70 mm (2.75") from the end of the PROFIBUS PA
cable, and thread the wires through the gland2.
2. Connect the wires to the terminal as shown:
Probe LU (PROFIBUS PA) is not polarity-sensitive.
Note: Ideally, mount SITRANS Probe LU so that the face of the transducer is at least
300 mm (1 ft) above the highest anticipated level.
WARNINGS:
DC terminals shall be supplied from an SELV1source in accordance with
IEC-1010-1 Annex H.
All field wiring must have insulation suitable for rated voltages.
1. Safety Extra Low Voltage
Note:
• For detailed wiring instructions, please see the full manual.
• For Intrinsically Safe setups (FM/CSA Class I, Div. 1), see
FM/CSA Intrinsically Safe
Connection Drawing on page 1 of Appendix A, for drawing number 23650617.
• For Non-Incendive setups (FM: Class I, Div. 2), see FM: Class I, Div. 2 Connection Drawing
on page 5 of Appendix A, for drawing number 23650583.
• The non-metallic enclosure does not provide a continuous ground path between conduit
connections: use grounding-type bushings and jumpers.
• Separate cables and conduits may be required to conform to standard instrumentation
wiring practices, or electrical codes.
2. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.

3. Ground the instrument according to local regulations.
• For Intrinsically Safe applications, connect the cable shield to the instrument shield
connection1, and ground the shield connection to an external ground that is
connected to an equal-potential grounding grid. For more detail on Explosion
Protection, you can download the brochure
Siemens Process Automation Explosion
Protection (part number A5E00265440) from www.siemens.com/level, under
Brochures/General.
• For General Purpose applications, ground the shield at one point only (usually the
power supply side) and continue the shield from device to device, connecting it to
the shield connection in each Probe LU.
4. Tighten the gland to form a good seal.
5. Close the cover and tighten screws: please do not overtighten screws. Recommended
torque is 0.5 to 1.1 N-m (5 to 10 in-lb).
Communications via PROFIBUS PA
Configuring the PROFIBUS PA master
To configure SITRANS Probe LU on the network, you will need the GSD file. You can download
the files (SIEM8124.gsd for the 6 m Probe LU, or SIEM8123.gsd for the 12 m Probe LU) from our
web site. Go to the SITRANS Probe LU product page at:
https://pia.khe.siemens.com/index.asp?Nr=11157 and click Downloads.
Startup
SITRANS Probe LU automatically starts up in RUN mode, and detects the material level. The
LCD displays the material level referenced from the Low Level Point2(the output of Analog
Input Function Block1/AIFB1). System status is displayed on the LCD, or on a remote
communications terminal.
1. The instrument shield connection is internally connected to the external ground lug.
Note: 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.
Notes:
• The following instructions assume that the user is familiar with PROFIBUS PA.
• For a complete list of applicable parameters, please see the full manual.
