Danger
The safety devices and the interconnection to
the machinery have to comply with the basic
safety requirements as mentioned in the cur-
rent regulations and standards.
Direct interfacing of a safety light curtain to
machine control that does not meet the neces-
sary safety integrity level, i.e. use of general
purpose PLCs or general purpose relays can
cause serious injury or death of persons.
Consult a professional safety engineer!
