4.9 Failure alarm box (FAB)
A FAILURE ALARM BOX (FAB) must be installed on
SV 300 equipped with MON-PROM V5.01. The
alarm functions of the FAB are integrated on
MON-PROM V6.00/PC 1608E and the FAB is not
used on SV 300 equipped with MON-PROM
V6.00/PC 1608E (or higher). See section
”4 MONITORING” for further information
regarding PROM and PC board versions.
The FAB is mounted on the SV 300
connector N81. All functionality of the SV
300 Analog
I/O terminal N81 is available through the
one-to-one connected FAB connector N81.
The FAB includes the functional blocks:
+24 V MONITOR
FAB INTERNAL MONITOR
ALARM CONTROL
A FAB BEEPER, a red LED, a push button and
the connector N81 (as described above) are
also included in the FAB.
The FAB is designed to detect loss of the
SV 300 internal +24 V power and emits
audible alarm in response to such a power
failure or in case of a FAB internal failure.

FAB, contact your Siemens representative.
