6.8.1 Alarm list
Central faults
Central faults are hardware faults which do no longer permit a dialog via the
2 Mbit/s interface. In this case, AIS must be sent to F1out provided that this
is still possible. Analog connections are released and blocked.
Central faults include:
• failure of the central controller
• failure of bus lines
• failure of a non-redundant system power supply.
Central alarms
Central alarms are those caused by a signal failure at F1in or by a failure of
central modules and circuits still permitting data transmission via the F1out
interface.
Central alarms include:
Faults in the configuration memory
• external clock failure
• synchronization clock failure at T3in
• failure of a doubled power supply
Note: The alarm contact ZA(A) is not available on each Central
Unit type.
