5.3 SIL High Alarm test
The SIL High Alarm Test is based on using the Rosemount 5900 gauge to measure the distance
from the SIL Reference Point to a reference reflector placed above the current SIL High Alarm
(see Figure 4-9 on page 22 and Figure 4-10 on page 23). Prior to the test, the Rosemount Tank
Gauging Safety System must be installed and configured as described in appropriate reference
manuals and the Rosemount 5900 and 2410 Safety Manual.
The test will detect approximately 96% of the DU (dangerous undetected) failures not detected
by the diagnostics in the Rosemount Tank Gauging Safety System.
Make sure that a Proof Test Reference Reflector is installed and configured as described in the
Rosemount 5900 Manual Supplement (Document No. 00809-0200-5900).
Ensure that SIL High Alarm Limit is located at least 500 mm below Reference Reflector.
See Figure 4-9 on page 22 for information on tank geometry.
