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)
WARNING: Changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.
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.

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.

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.

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 gland1.
2. Connect the wires to the terminal as shown:
Probe LU (PROFIBUS PA) is not polarity-sensitive.
3. Ground the instrument according to local
regulations.
• For Intrinsically Safe applications, connect
the cable shield to the instrument shield
connection2, 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).
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.
1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.
2. 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.

Instructions specific to hazardous area installations
(Reference European ATEX Directive 94/9/EC, Annex II, 1/0/6)
The following instructions apply to equipment covered by certificate number SIRA
06ATEX2357X:
1. For use and assembly, refer to the main instructions.
2. The equipment is certified for use as Category 1G equipment.
3. The equipment may be used with flammable gases and vapors with apparatus
group IIC and temperature class T4.
4. The equipment is certified for use in an ambient temperature range of –40 C to
80 C.
5. The equipment has not been assessed as a safety related device (as referred to by
Directive 94/9/EC Annex II, clause 1.5).
6. Installation and inspection of this equipment shall be carried out by suitably trained
personnel in accordance with the applicable code of practice (EN 60079-14 and
EN 60079-17 in Europe).
7. Repair of this equipment shall be carried out by suitably trained personnel in
accordance with the applicable code of practice (e.g. EN 60079-19 within Europe).
8. Components to be incorporated into or used as replacements in the equipment shall
be fitted by suitably trained personnel in accordance with the manufacturer’s
documentation.
9. It is the responsibility of the user to ensure that manual override is possible in order
to shut down the equipment and protective systems incorporated within automatic
processes which deviate from the intended operating conditions, provided that this
does not compromise safety.
10. The ‘X’ suffix to the certificate number relates to the following special conditions for
safe use:
a. Parts of the enclosure may be non-conducting and may generate an ignition-
capable level of electrostatic charge under certain extreme conditions. The
user should ensure that the equipment is not installed in a location where it
may be subjected to external conditions (such as high-pressure steam) which
might cause a build-up of electrostatic charge on non-conducting surfaces.
b. As either Aluminum, Magnesium, Titanium or Zirconium
may be used at the
accessible surface of the equipment, in the event of rare incidents, ignition
sources due to impact and friction sparks could occur. This shall be considered
when the SITRANS Probe LU (PROFIBUS PA) is being installed in locations that
specifically require group II, category 1G equipment.
