Safety Instrumented Systems Requirements
5. Perform a two-point verification
(1)
of the transmitter pressure over the full working range (and
process temperature where applicable).
6. Remove the bypass and otherwise restore the normal operation.
7. Place the Security switch in the (
) position.
Note
The user determines the proof test requirements for impulse piping.
Automatic diagnostics are defined for the corrected % DU: The tests performed internally by the
device during runtime without requiring enabling or programming by the user.
6.6
Inspection
6.6.1
Visual inspection
Not required
6.6.2
Special tools
Not required
6.6.3
Product repair
The Rosemount 3051SMV is repairable with limited replacement options.
All failures detected by the transmitter diagnostics or by the proof-test must be reported. Feedback can
be submitted electronically at
Emerson.com/Rosemount/Report-A-Failure
All product repair and part replacement should be performed by qualified personnel.
6.6.4
Rosemount 3051SMV SIS reference
The Rosemount 3051SMV must be operated in accordance to the functional and performance
specifications provided in
“Specifications and Reference Data” on page 125
.
6.6.5
Failure rate data
The FMEDA report includes failure rates and the assumptions for how these failure rates were derived.
The report is available under
Certificates and Approvals
at
Emerson.com/Automation-Solutions/Pressure/Rosemount-3051SMV
6.6.6
Failure values
Safety Deviation (defines what is dangerous in a FMEDA): ±2.0% of analog output span
Transmitter response time: provided in
“Dynamic performance ambient temperature effect” on
Self-diagnostics Test Interval: At least once every 60 minutes
1.
If the two-point process temperature verification is performed with electrical instrumentation, this proof test will not detect any failures of the sensor.
