11.5 Status Messages and Diagnostics Information
These messages are shown on page 3 of the display. mA- and status outputs can be set so that
error messages are signalled, see Section 10.4, Fct. C 3.x.4 (current) and Fct. C 3.x.1 (status).
Please note: for settings with mA and/or status outputs:
- out of specification (S) = all errors of Categories S, F and F
- application error (F) = all errors of Categories F and F
- fault in device (F) = all errors of Category F
