• Under no circumstances should safety contacts OSSD1 and
OSSD2 be wired in series or parallel; however, both may be used
separately.
If one of these two configurations should be used by mistake, the
safety light curtain will indicate an output malfunction (see Ch. 7
“Diagnostic functions”).
• Connect both OSSD outputs to the control element. If an OSSD
output is not connected to the control element, this will have a
negative effect on the safety level of the system in which the safety
light curtain is used.
