How to select a passive barrier for SITRANS LR250
To make sure that the barrier safety description is suitable for the LR250 Intrinsically Safe (IS)
input parameters, carry out the following calculations:
Re-e = max. end-to-end resistance of the barrier
Rloop = loop resistance (total of cable resistance plus e.g. sense resistance,
displays, and/or PLC inputs)
Vbarrier = value of any non-linear voltage drops due to the barrier
1. Determine the value for Re-e from the data sheet.
2. Calculate the total value for Rloop: by adding, for example, sense resistance, displays,
and/or PLC inputs.
3. Calculate Rworking = Re-e + Rloop.
4. Determine the value of Vbarrier from the barrier data sheet (for example, voltage drops
due to diodes).
5. Calculate Vworking = Vsupply – Vbarrier.
6. Use the values for Vworking and Rworking to confirm that operation is within the shaded
area of the graph
Loop Voltage versus Loop Resistance on page 21.

SITRANS LR250 Communications: HART
• You will need the full manual to acquire the list of applicable parameters.
• We recommend that you use SIMATIC Process Device Manager (PDM) to program your
device.
SIMATIC PDM
SIMATIC PDM is a software package used to commission and maintain SITRANS LR250 and
other process devices. Please consult the operating instructions or online help for details on
using SIMATIC PDM. (You can find more information at www.fielddevices.com: go to Products
and Solutions > Products and Systems > Communications and Software > Process Device
Manager.)
Device Description (DD)
• You can locate the DD in Device Catalog, under Sensors/Level/Echo/Siemens Milltronics/
SITRANS LR250.
• Check the product page of our website at: www.siemens.com/LR250, under Downloads,
to make sure you have the latest version of SIMATIC PDM, the most recent Service Pack
(SP) and the most recent hot fix (HF). If you need to install a new DD see
Configuring a
new device below.
Configuring a new device
1. Check that you have the most recent DD, and if necessary download it from the product
page listed above. Save the files to your computer, and extract the zipped file to an easily
accessed location. Launch SIMATIC PDM – Manager Device Catalog, browse to the
unzipped DD file and select it.
2. Launch SIMATIC PDM and create a new project for LR250. Application Guides for setting
up HART devices with SIMATIC PDM can be downloaded from the product page of our
website at: www.siemens.com/LR250.
3. Upload parameters to the PC/PG.
4. Configure the device via the Quick Start wizard (see page 19).
Note: SITRANS LR250 requires the DD for SIMATIC PDM version 6.0 with SP2 and HF1, or
higher.
Note: Clicking on Cancel during an upload from device to SIMATIC PDM will result in some
parameters being updated.
