    S1 and S2. If a type 2 AOPD is to be muted, the muting area 1 must be set to "S1 only" via MU4 (up) and the type 2 AOPD to be muted must be connected to S1. For DIP switch settings, Leuze electronic GmbH + Co. KG MSI-m(E)/R...

  • Page 16: Sequential Muting, Connections At M1 To M4

    Parallel double muting is not possible with MSI-m. If muting is needed for two independent areas, e.g. the entrance and exit area of a packaging line, the extended safety interface MSI-mx(E)/Rx takes on this task. Ask Leuze electronic or its local representatives for further information. 4.3.2.4 Testable and non-testable muting sensors The following devices are suitable for use as muting sensors: •...
