Section 6: Certified Safety Instrumented System (Safety-Certified)
April 2014
Certified safety instrumented system (safety-certified)
6.7 Certification
The 3144P is certified to IEC61508 for single transmitter use in Safety Instrumented Systems up
to SIL 2 and redundant transmitter use in Safety Instrumented Systems up to SIL 3. The software
is suitable for SIL 3 application.
6.8 3144P safety-certified identification
To identify Safety Instrumented System (SIS) safety-certified 3144P transmitters, verify one of
the following:
1. See a yellow tag affixed to outside of transmitter.
2. Verify the option code QT in the model string.
6.9 Installation
No special installation is required in addition to the standard installation practices outlined in
this document. Always ensure a proper seal by installing the electronics housing cover(s) so that
metal contacts metal.
Environmental limits are available in the 3144P Product Data Sheet
(Document No. 00813-0100-4021). This document can be found at http://www.emersonpro-
cess.com/rosemount/safety/safetyCertTemp.htm.
The loop should be designed so the terminal voltage does not drop below 12 Vdc when the
transmitter output is 24.5 mA.
6.10 Commissioning
The 3144P Safety Certified Transmitter can be commissioned by a person with average
knowledge of Rosemount temperature transmitters and the configuration device being used.
To commission the 3144P Safety Certified Transmitter, use the HART “Fast Key Sequences” on
page 38.
For more information on the Field Communicator see Document No. 00809-0100-4276. AMS
