Rosemount 5300 Series

OVERVIEW

Applicable Models

The following section applies to the 4-20 mA Rosemount 5300 Prior-Use option (Special certification: QS) transmitter used in Safety Instrumented Systems (SIS) applications. The 5300 Prior-Use option with analog output provides overfill and empty tank protection to improve the system safety. The transmitter is classified as a Type B device. It contains self-diagnostics and is programmed to send its output to either a high or low failure state upon internal detection of a failure.

An independent FMEDA (hardware assessment) was conducted by Exida according to IEC 61508. The FMEDA is performed to determine failure rates, calculate the Safe Failure Fraction (SFF), and the average Probability of Failure on Demand (PFDAVG). The hardware assessment is one of the steps taken to achieve functional safety per IEC 61508.

NOTE:

Refer to the 5300 FMEDA(1) report for failure rate data, assessment details, and assumptions regarding failure rate analysis.

Table 8-1lists the versions of the Rosemount 5300 Series transmitter that have been considered for the hardware assessment, to which this section applies.

To identify a 5300 Prior-Use option transmitter:

•Verify the option code QS in the model code, on the label affixed to the outside of the transmitter head or

•375 Field Communicator: HART Sequence [1, 7, 8]. Verify that Prior-Use safety device is ON

•Open Rosemount Radar Master, right click on the device, and select properties. Verify that the Safety Device (QS Option) is present

Skill Level of Personnel

It is assumed that the personnel installing, configuring, and operating the system have the knowledge equal or greater than that of a qualified Instrument Technician familiar with safety-related systems, process control applications and general instrument use.
