Defines the assignment of the safety-oriented digital inputs of the FSC.
If not all the input signals of an FSC input configuration are used, these must be connected according to the notices in the footnotes.
- Safety interlock circuit before fan start
-
Safety-oriented input for connecting the monitors and limiters required for start-up and operation of the combustion air fan.
- Safety interlock circuit after fan start
-

Note
If the safety interlock circuit is not included in the FSC input configuration after fan start, then monitoring of the safety interlock circuit monitors and limiters must take place in the following safety interlock circuits after fan start:
-
Safety interlock circuit before fan start
-
