Figure 8-1. Alarm Levels and Operation Values
It is assumed that the current output signal is fed to a SIL 2-compliant analog input board of
a safety logic solver. For instructions on alarm level settings see section
Note
Only the High or Low Alarm Mode can be used for the safety function. Do not choose Freeze
Current.
Write protection
A Rosemount 5300 Series safety-certified transmitter should always be protected from
unintentional configuration changes by a password protected function. It is recommended
to use write protection described in section
“Write protecting a transmitter” on page 174
Site acceptance
After installation and/or configuration, proper operation of the transmitter (including
verification of all configuration changes) must be verified. A site acceptance test is therefore
required. The proof test outlined in this document can be used for this.
