Operating Manual
•
Under no circumstances should safety outputs OSSD1 and OSSD2
be wired in series or in parallel (Fig. 15, 16, 17); both must be used
separately, as shown in Fig. 14. Should one of these two
configurations be used in error, a malfunction will occur (see Ch. 7,
"Diagnostic function").
