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 SIL* 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.
