Installation and Configuration
4.2.6 Safety alarm configuration
Prior to setting up a Rosemount Tank Gauging Safety System it shall be installed and configured
as a regular Rosemount Tank Gauging system. See the Rosemount Tank Gauging System
Configuration Manual and the reference manuals for the various Rosemount Tank Gauging
devices for more information. A list of documents is available in Section 2: Reference Documents.
Once the devices are up and running, the SIL safety alarm can be configured by using the Safety
Alarm function in TankMaster WinSetup.
Prior to starting the Safety Alarm Configuration procedure, check the following:
Make a note of the Device Id of the 5900, see Appendix C: Safety System Identification
Verify that the SIL Baselines for the 5900 and 2410 are identical, see Appendix C: Safety
System Identification
Verify that the 5900 is equipped with a terminal block that supports the required SIL,
see
Appendix C: Safety System Identification
Verify that the 5900 and 2410 have the same SIL Level (both SIL 2 or both SIL 3), see
Appendix C: Safety System Identification
Make a note of the antenna type, it is typed on a label attached to the 5900 antenna,
see
Appendix B: Supported Antennas
In overfill applications Safety Alarm Configuration must be performed with the product
surface at least 1 m below the SIL High Alarm Limit
There must not be any objects that may cause disturbing echoes within 1 meter from
the product.
For 5900 with LPG/LNG antenna, verify that the verification pin is visible above the
product surface
For dry-run applications, the surface level must be a maximum of 125 mm above the SIL
Low Alarm Limit
The SIL 3 Rosemount Tank Gauging Safety System includes a 2-in-1 Rosemount 5900 with two
independent radar level gauges using the same antenna and tank opening. The Safety Alarm has
to be separately configured for each of the two gauges as described in “Safety alarm
configuration procedure” on page 32.
Note
The Rosemount 5900 Radar Level Gauge is not safety-rated during maintenance work,
configuration changes, or other activity that affects the Safety Function. Alternative means
should be used to ensure process safety during such activities.
