SIS operation and maintenance
Proof test
The following proof test is recommended. If an error is found in the safety function, the
measuring system must be switched out of service and the process held in a safe state by
means of other measures. Proof test results and corrective actions taken must be
documented at
EmersonProcess.com/Rosemount-Safety
Note
For a valid result, always perform the proof test on the product that will be stored in the
tank while the device is in operation.
Note
Before every test, make sure you are connected to the correct transmitter by verifying
QT/QS in the model code on the label and your software version. Also verify that the serial
number on the label matches the one in your configuration tool.
Make sure to enable write protection as soon as you are finished.
Required Tools: HART host/communicator and mA meter.
Note that prior to these tests, inspect the echo curve to ensure that no disturbing echoes
affecting the measurement performance are present.
