SITRANS Probe LU
SITRANS Probe LU is a loop-powered continuous level monitor, using advanced ultrasonic
techniques. The unit 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.
Communicationis via HART1, andsignals areprocessedusingSonic Intelligence®.
Specifications
For a complete listing, see the SITRANS Probe LU Instruction Manual. For Approvals
information, please refer to the product nameplate.

Mounting Location
Recommendations:
• Ambient temperature within –40 to 80 oC (–40 to 176 oF).
• Easy access for viewing the display and programming via the hand programmer.
• 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.
•Avoidinterferencetothe soundpathfromobstructionsorfromthe fill path.
Mounting Instructions
SITRANS Probe LU is available in three thread types: 2" NPT, 2" BSP, or PF2/G.
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.

Fill
The sound path should be:
• perpendicular to the
monitored surface
• clear of rough walls,
seams, rungs, or
other obstructions
• clear of the fill path

Wiring
Power1
Connecting SITRANS Probe LU
3. Strip the cable jacket for approximately 70 mm (2.75") from the end of the cable, and
thread the wires through the gland2.
4. Connect the wires to the terminals as shown above: the polarity is identified on the
terminal block.
5. Tighten the gland to form a good seal.
6. Close the cover and tighten screws: please do not overtighten screws.
Recommended torque is 1.1 to 1.7 N-m (10 to 15 in-lb).
WARNINGS:
DC terminals shall be supplied froman SELV 1source in accordance
with IEC-1010-1 Annex H.
All fieldwiring must have insulation suitable for rated voltages.
1. Safety Extra Low Voltage
Notes:
• For detailed information on Intrinsically Safe set-ups, please see the full manual.
• Use shielded, twisted pair cable (wire gauge AWG 22 to AWG 14 /0.34 mm2to 2.08 mm2).
• Separate cables and conduits may be required to conform to standard instrumentation
wiring practices, or electrical codes.
• The non-metallic enclosure does not provide a continuous ground path between conduit
connections: use grounding-type bushings and jumpers.
2. If cable is routed through conduit, use only approved suitable-size hubs for waterproof application.

RUN Mode and PROGRAM Mode
SITRANS Probe LU has two modes of operation: RUN and PROGRAM.
SITRANS Probe LU automatically starts in RUN mode when power is applied, and detects the
material level. The primary reading displays the material level (in meters) referenced from
Empty (process empty level). This is the default start-up display mode.
System status is displayed on the LCD, or on a remote communications terminal.
RUNModeDisplay
Use the hand programmer to control the display.1
If the echo confidence drops below the echo confidence threshold, the failsafe timer starts
running. When the timer expires, the letters LOE (Loss of Echo) alternate with the reading
every two seconds, and the Reliable Echo indicator is replaced by the Unreliable indicator.
When a valid reading is received, the level reading display returns to normal operation.
PROGRAM Mode Display2
1 – Primary Reading (displays level, distance, or volume1, in either units or percent).
2 – Secondary Reading (displays Parameter number for Auxiliary Reading2)
3 – Echo status indicator: Reliable Echo or Unreliable Echo
4 – Units or Percent
5 – Active bar graph represents material level
6 – Auxiliary Reading (depending on the parameter selected, it displays milliAmp value,
distance, or echo confidence, with units where applicable.)

Programming
• Set parameters to suit your specific application.
•ActivatePROGRAM mode at any time, to change parameter values and set operating
conditions.
• For local programming, use the Siemens Milltronics hand programmer.
• For programming from a distance, use either a PC running SIMATIC PDM, or a HART
handheld communicator.
Hand programmer
Low temperature effects on RUN/PROGRAM modes
If the internal temperature falls to –30 oC (–22 oF) or below, it will affect both RUN and
PROGRAM modes.
RUN mode will operate normally, with the following exceptions:
• hand programmer operation is disabled
• the LCD displays only limited information: the bar graph and the reliable/unreliable echo
indicator
PROGRAM mode:
• hand programmer operation is disabled
