NOTE!

The Rosemount 5300 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.

The Safety Function is based on the analog output 4-20 mA, used as the safety variable. It is configured to activate the alarm function if an error occurs or if the measured value goes beyond the measurement range set by the user.

Only the 4-20 mA output can be used in the Safety Function. The HART protocol can only be used for setup, calibration, and diagnostic purposes, not for safety critical operation. The measurement signal used by the logic solver must be the analog 4-20 mA signal proportional to the level generated.

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 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 8-2, when the transmitter output is 22.5 mA.

Installations

Use a HART-compliant master, such as Rosemount Radar Master or 375 Field Communicator, to communicate with and verify configuration of the Rosemount 5300. A full review of configuration methods is available in Section 5: Configuration. These instructions are applicable to the 5300 Prior-Use option with any differences noted.

User adjusted damping will affect the transmitter’s ability to respond to process changes. Therefore, the damping values + response time should not exceed the loop requirements. For further information on damping, see “Echo Tracking” on page C-12.
