13.9.1 Status output active state
The status output can be compared to an electrical relay that can function as make or break contact. For
safety-relevant applications, the operator will choose the break contact setting so that a power failure or
failure of the electronics can be detected like an alarm. In standard applications, the output is used as
make contact.
The
Status output state active state function allows the operator to define the behavior of the status out-
put.

13.9.2 Status output 1 assignment

general assignment is the alarm assignment because all set limiting values and the self-test function are
then monitored via the status output.
After selecting the
Status output assignment function, press ↵ to display the current assignment.
