Issue:
How to wire a SIL Interface Avatar for the different SIL stop 0 applications?
Product Line:
Motor Management system Tesys Island
Environment:
IEC Contactors and Starters
Resolution:
Examples: SIL STOP Category 0
Wiring Category 1
The safety-related sensor element can be directly wired to the SIL-IN/SIL Common inputs. The Mirror In/Mirror Out inputs are not used.
Refer to page 43 Functional Safety Guide Link
Wiring Category 2
The safety-related sensor element is wired to a Preventa XPS module (or equivalent). The Preventa XPS module (or equivalent) outputs are wired to the SIL-IN/SIL Common inputs of the SIL8 interface module. To meet the requirement for Category 2, the mirror contact feedback (Mirror In/ Mirror Out) must be monitored by a Preventa XPS module (or equivalent) that performs external diagnostic monitoring of the mirror contact. If the mirror contact does not close on stop, the next restart is prevented to all SIL starters in the SIL group.

Wiring Category 3/4
A single fault will not lead to the loss of the safety function and whenever practicable, the single fault shall be detected at or before the next demand on the safety function. To meet the requirement for Category 3, the mirror contact feedback (Mirror In/ Mirror Out) must be monitored by a Preventa XPS module (or equivalent) that performs external diagnostic monitoring of the SIL10 starter’s mirror contact. If the mirror contact does not open on stop, the next restart is prevented for all SIL starters in the SIL group. The safety-related sensor element is wired to a Preventa XPS module (or equivalent). The Preventa XPS module (or equivalent) outputs are wired to the SIL-IN/SIL Common inputs of the SIL interface module.
