AND-linked safety inputs (sensor inputs)
E.g. emergency stop button, position switch, electromagnetic switch, light curtain, ...
All emergency stop buttons and light curtains with FUNCTION 1 from
the SA-BM-S1 and the SA-IN-S1 input expansion are AND-linked.
AND-linked safety inputs (sensor inputs)
The non-contact inductive safety sensor S1 with test input (e.g. GM 504S, GM505S from
ifm) and the testable light barrier LC1 are AND-linked. Both sensors must be actuated
before a new Reset can be initiated. The emergency stop button ES1 at SA-BM-S1 has
priority over the enabling input on the right SA-BM-S1 by AND operation.
