The OSSD1 and OSSD2 safety contacts cannot be connected
in series or in parallel, but can be used separately (Fig.15). If
one of these configurations is erroneously used, the device
enters into the output failure condition (see cap.7 “Diagnostic
functions”).
Connect both OSSD to the activating device. The avoided
connection of an OSSD to the activating device jeopardises the
system safety degree that the light curtain has to control.
