WARNING: Changes or modifications not expressly approved by Siemens 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 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, in which case the user will be required to correct the interference at his own expense.

Application Examples

The application examples used in this manual illustrate typical installations using SITRANS Probe LR. Because there is often a range of ways to approach an application, other configurations may also apply.

WARNINGS:
• Installation shall only be performed by qualified personnel and in accordance with local governing regulations.
• SITRANS Probe LR ‘is to be used only in the manner outlined in this manual, otherwise protection provided by the device may be impaired.
• Never attempt to loosen, remove, or disassemble process connection or instrument housing while vessel contents are under pressure.
• This product is designated as a Pressure Accessory per Directive 97/ 23 / EC and is not
• Materials of construction are chosen based on their chemical compatibility (or inertness) for general purposes. For exposure to specific environments, check with chemical compatibility charts before installing.
• The user is responsible for the selection of bolting and gasket materials which will fall within the limits of the flange and its intended use and which are suitable for the service conditions.
• Improper installation may result in loss of process pressure.
Notes:
• Refer to the device nameplate for approval information.
• The Process Device Tag shall remain with the process pressure boundary assembly1. In the event the instrument package is replaced, the Process Device Tag shall be transferred to the replacement unit.
• SITRANS Probe LR units are hydrostatically tested, meeting or exceeding the requirements of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment Directive.
• The serial numbers stamped in each process connection body provide a unique identification number indicating date of manufacture. Example: MMDDYY – XXX (where MM = month, DD = day, YY = year, and
Further markings (space permitting) indicate flange configuration, size, pressure class, material, and material heat code.

Recommendations:

Ensure ambient temperature is within –40 to 80 oC (–40 to 176 oF).
Provide easy access for viewing the display and programming via the handheld programmer.
Ensure the environment is suitable to the housing rating and materials of construction.

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 emission cone from obstructions or from the fill path.
Avoid central locations on vessels.

WARNING: For vessels with conical or parabolic tops, avoid mounting the instrument at the centre. (The concavity of the top can focus echoes into the centre, giving false readings.)
Note:
Under certain circumstances, it may be acceptable to mount SITRANS Probe LR at the centre of a flat-topped tank: please discuss this with your Siemens Milltronics representative.

Notes:
• Beam angle is defined at the

• For more detail on false echoes, see
False-Echo
Suppression
on page 94.
Make allowance for the emission cone spreading: allow a minimum of 300 mm (1 ft) for every 3 m (10 ft) of vessel height.
Locate the antenna away from the side wall, to avoid interference from indirect echoes.
Avoid interference from objects such as ladders or pipes, which can cause false echoes.
Make sure the beam angle does not intersect the fill path.

Notes:
• Use the 100 mm (4") shield on nozzles that are 100 mm (4") in length, or shorter.
• Use the 250 mm (10") shield on nozzles that are 250 mm (10") in length, or shorter.
• If your nozzle is longer than 250 mm (10"), contact your local representative. You will need to exchange the device for a different model with a longer shield length.
On a nozzle, the end of the shield section should protrude a minimum of 10 mm (0.4”) to avoid interference.
A manhole cover is typically a covered nozzle with a diameter of 610 mm (24”) or greater. To provide optimum signal conditions on a manhole cover, locate the antenna off-center, typically 100 mm (4") from the side.
Note: For details on other applications, see
page 98.
Appendix F: Special Applications

Mounting Instructions

Note: Do not rotate the enclosure after programming and vessel calibration, otherwise
an error may occur, caused by a polarity shift of the transmit pulse.
1. Before inserting SITRANS Probe LR into its mounting connection, check to ensure the threads are matching, to avoid damaging them.
Installation
2. Simply screw SITRANS Probe LR into the process connection, and hand tighten. For pressure applications, it will be necessary to use PTFE tape (or other appropriate thread sealing compound) and tighten the process connection beyond hand tight.
The maximum torque is 40 N-m (30 ft.lbs.).
3. If you want to rotate the enclosure, use a 2 mm Allen key to loosen the three set­screws that secure the locking collar.
4. Once the enclosure is in a suitable position, tighten the set-screws.

Notes:
Use shielded, twisted pair cable (wire gauge AWG 14 to 22).
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.

SITRANS Probe LR has two modes of operation: RUN and PROGRAM.

RUN Mode

Operation
SITRANS Probe LR 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.

Display

1 – Primary Reading (displays level, distance, or volume, in either units or percent)
2 – Secondary Reading (displays Parameter number for Auxiliary Reading1)
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 confidence, with units where applicable)
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 Echo indicator. When a valid reading is received, the level reading display returns to normal operation.

PROGRAM Mode

Programming

Set parameters to suit your specific application.
•Activate PROGRAM mode at any time, to change parameter values and set operating conditions.
For local programming, use the Siemens handheld programmer.
For programming from a distance, use either a PC running SIMATIC PDM, or a HART handheld communicator.
Operation
Note: Do not use the handheld programmer at the same time as SIMATIC PDM, or
erratic operation may result.

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.

handheld programmer operation is disabled
the LCD displays only limited information: the bar graph and the reliable/
unreliable echo indicator
PROGRAM mode:
handheld programmer operation is disabled

2. Select the measurement mode: level, space, or distance (P001).
3. Set the response time to level changes (P003).
4. Select units of measurement: m, cm, mm, ft, or in. (P005).
5. Set process empty level (Empty: P006).
6. Set the range to be measured (Span: P007).
7. To ignore false echoes before the material echo, set Auto False-Echo Suppression Distance (P838).
8. Enable Auto False-Echo Suppression (P837).
9. Return to RUN mode.

Setup Instructions

Notes:
•In PROGRAM mode, you can use the ARROW keys to scroll to a parameter number.
• The default parameter values are indicated by an asterisk (*) in the tables.
Using the handheld programmer, set each parameter value to suit your application. (For detailed instructions on accessing a parameter and changing the value, see page 22.)
