Preventa XU - How to wire the XU2S18PP340L5 sensors to the safety controller XPSMCM?

The association XU2S18PP340* photo cells + XPSMCM safety controller, is not possible. Legally the XU2S18PP340* is declared to be a type 2 light curtain, when it is combined to the XPSCM1144 monitoring relay (EC type-examination for both components). Technically the XPSMCM safety controller can be associated to a complete and certified safety curtain type 2 or type 4, like the XUSL2E or XUSL4E. The compact XUSL2E light curtain is equivalent to the association XU2S18PP340* photo cells + XPSCM1144 unit.
