Example: connection to the safety relay.
Fig. 17
The figures show the connection between the safety light curtains and the safety relay of the SE-SR2
series functioning in the Automatic Start mode (left side) and Manual Start with monitoring (right side).
Do not use varistors, RC circuits or LEDs in parallel at relay inputs or in series at OSSD outputs.
The OSSD1 and OSSD2 safety contacts cannot be connected in series or in parallel, but can be
used separately (Fig.18). If one of these configurations is erroneously used, the device enters into
the output failure condition (see chapter 7 “Diagnostic functions”).
