What mounting tips can you give for single beam polarised reflex type detectors with the mute function connected to an XPSCM11

Summary of the mute function of an XPSCM Preventa module:

The Preventa XPSCM module mute mechanism allows materials to be transported across the protection field provided by the light guard without the safety outputs being deactivated. 

A person cannot activate the mute detectors in the same way and will cause the system to stop if he/she enters the danger zone.

When a moving part, length dM<m, enters the area between the two points MS1 and MS2 , the "muting" input on the XPSCM1144 product is closed (MS1 or MS2 output closed). The XPSCM1144 module then behaves as though the beams of detectors D1, D2 and D3 were not obstructed: "muting" function

Mounting the detectors

The best solution is to cross the transmitters with the reflectors (see below), rather than install the 2 polarised reflex type detectors either side of the guard.

3-wire PNP dark switching only detectors should be used for this function, part numbers XUB0BPSNLx + XUZC50.
