Emerson 00825-0100-4530 Rev EC manual Safety Instrumented Systems 4-20mA only, Installation

March 2013 Quick Installation Guide

Safety Instrumented Systems (4-20 mA only)

The following section is applicable to the Rosemount 5300 Prior-Use option (Special certification: QS). Additional Safety Instrumented Systems information is available in the Rosemount 5300 Series Reference Manual (Document No.

00809-0100-4530). The manual is available electronically at www.rosemount.com or by contacting an Emerson Process Management representative.

To identify a 5300 Prior-Use option transmitter:

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

Handheld HART Communicator: Fast Key Sequence [1, 7, 8]. Verify that the Prior-Use safety device is ON or

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

Installation

The device should be installed and configured as a level sensing device per manufacturer’s instructions. The materials must be compatible with process conditions and process fluids. No special installation is required in addition to the standard installation practices outlined in this document.

Environmental limits are available in the Rosemount 5300 Series Reference Manual (Document No. 00809-0100-4530), Appendix A: Reference Data.

The loop must be designed so the terminal voltage does not drop below the minimum input voltage, see values in Table 2, when the transmitter output is 22.5 mA.

Table 2. Minimum input voltage (Ui) at different currents

			Current

Configuration

Use a HART-compliant master, such as Rosemount Radar Master or a Field Communicator, to communicate with and verify configuration of the Rosemount 5300 Series. A full review of configuration methods is available in the Rosemount 5300 Series Reference Manual (Document No. 00809-0100-4530).

NOTE:

The Rosemount 5300 Series transmitter is not safety-rated during maintenance work, configuration changes, multidrop, loop test, or other activity that affects the Safety Function. Alternative means should be used to ensure process safety during such activities.
