Note: Only terminals S1 and S3 can be used for
the emergency shutoff function. For
details, refer to "Emergency Shutoff
Function" (page 2-10).
PSC Multi-function input
common The sink and source logic for contact input can
be switched by connecting a short-circuit bar on
the control terminal block.

alarm factor code (e.g. Inverter trip). The signal
between each terminal and PC always
