5 Functional safety (SIL)
SOLITRAC 31 • Four-wire 4 … 20 mA/HART
62085-EN-211203
All parameters changed by the operator are automatically stored
temporarily so that they can be verified in the next step.
After setup, the modified parameters must be verified (confirm the
correctness of the parameters). To do this, you first have to enter the
PIN. Here the adjustment is locked automatically. Then you carry
out a comparison of two character strings. You must confirm that the
character strings are identical. This is used to check the character
presentation.
Then you confirm that the serial number of your instrument has been
carried over correctly. This is used to check device communication.
Then, all modified parameters that have to be confirmed are listed.
After this process is terminated, the safety function is again ensured.
Warning:
If the described process was not carried out completely or correctly
(e.g. due to interruption or voltage loss), the instrument remains in an
unlocked, and thus unsafe, status.
Warning:
In case of a reset to basic settings, all safety-relevant parameters will
also be reset to default. Therefore all safety-relevant parameters must
be checked or readjusted.
