Rosemount 3144P
6-2
Certified SIS
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 Sequence” on page 3-6.
For more information on the Field Communicator see Document No.
00809-0100-4276. AMS help can be found in the AMS on-line guides within
the AMS system.
CONFIGURATION
All configuration methods outlined in Section 3 are the same for the safety
certified 3144P temperature transmitter with any differences noted.
Damping and Alarm Levels
User-adjustable damping affects the transmitters ability to respond to changes
in the applied process. The
damping value + response time
should not
exceed the loop requirements.
NOTES
1. Transmitter output is not safety-rated during: configuration changes,
multidrop, and loop test. Alternative means should be used to ensure
process safety during transmitter configuration and maintenance activities.
2. DCS, or safety logic solver, should be configured to match transmitter
configuration. Figure 6-1 identifies the Emerson standard alarm and
saturation levels. Alarm and saturation values are user-configurable.
Setting the alarm values is a two step process
1. With a Field Communicator, select the alarm and saturation levels using
the following Traditional Fast key sequence 1, 3, 4, 2.
2. Position the Alarm switch to the required HI or LO position.

Security Switch
Position the security switch to the “ON” position to prevent accidental or
deliberate change of configuration data during normal operation.
(1) Transmitter Failure, hardware alarm in LO position.
(2) Transmitter Failure, hardware alarm in HI position.
