Safety Instrumented Systems Requirements
6.5
Rosemount 3051SMV SIS operation and maintenance
6.5.1
Proof test
The following proof tests are recommended.
All proof test procedures must be carried out by qualified personnel.
“Field Communicator Fast Keys” on page 62
to perform a loop test, analog output trim, or sensor
trim. security switch should be in the (
) position during proof test execution and repositioned in the
(
) position after execution.
6.5.2
Partial proof test
The partial suggested proof test consists of a power cycle plus reasonability checks of the transmitter
output. This test will detect
~
48% of possible DU failures in the device.

and look at the certificates and approvals documentation.
Required tools: Field Communicator and mA meter.
1. Bypass the safety function and take appropriate action to avoid a false trip.
2. Use HART communications to retrieve any diagnostics and take appropriate action.
3. Send a HART command to the transmitter to go to the high alarm current output and verify that the
analog current reaches that value
.
(1)
See
“Alarm level verification” on page 30
.
4. Send a HART command to the transmitter to go to the low alarm current output and verify that the
analog current reaches that value.
(2)
5. Perform a “reasonability check” on the pressure sensor reading and the sensor temperature reading
and if applicable the process temperature reading.
(3)
6. Remove the bypass and otherwise restore the normal operation.
7. Place the Security switch in the (
) position.
6.5.3
Comprehensive proof test
The comprehensive proof test consists of performing the same steps as the simple suggested proof test
but with a two point calibration of the pressure and temperature sensors in place of the reasonability
check of the sensors. This test will detect
~
90% of possible DU failures in the device.
Required tools: Field Communicator and pressure calibration equipment.
1. Bypass the safety function and take appropriate action to avoid a false trip.
2. Use HART communications to retrieve any diagnostics and take appropriate action.
3. Send a HART command to the transmitter to go to the high alarm current output and verify that the
analog current reaches that value.
“Alarm level verification” on page 30.
4. Send a HART command to the transmitter to go to the low alarm current output and verify that the
analog current reaches that value.
1.
This tests for compliance voltage problems such as a low loop power supply voltage or increased wiring resistance. This also tests for other possible
failures.
2.
This tests for possible quiescent current related failures.
3.
This tests for faults in the input multiplexer and A to D converter.
