Sil Error String - GE PanaFlow HT User Manual

4.2.4 SIL Error String

Note: Few of these errors will appear on the LCD. The LCD only shows the top priority error at any time.
Vitality software will list these error conditions in addition to the top priority error, as the PC display can show
more information.
SIL errors are generally faults detected during internal device monitoring of the flow measurement circuitry. To ensure
functional safety integrity, we must have absolute confidence in the integrity of our measurement hardware. These
errors show that we do not have full confidence in some part of the hardware, and must stop providing a measurement
to the SIS. More details and corrective actions are listed in the Functional Safety Manual.
Under normal operation, only S1 - "In Config Mode" is likely to appear on the error line. This is an indication that the
instrument is currently not measuring flow, because the instrument is in the Configuration mode. It also warns the
Operator that the SIL Output is not to be used as part of the SIS while in this mode of operation.
For troubleshooting details and more information on S errors, consult the Safety Manual.
