Alarm Card Alarm States
Alarm states are ranked from low severity to high severity.
Alarm State Severity
Major or PMJ ....................... Highest
Minor or PMN ...................... Medium
None or OK .............. Lowest (no alarm)
Alarm states are aggregated and combined into successively larger representations:
Converter circuit states are aggregated into a Converter Card state.
Converter Card states and -48V Input Feed states are aggregated and combined into a Converter Shelf state.
Converter Shelf states and Fan Shelf states are aggregated and combined into a Converter system state.
• System Alarm State - the highest alarm state within the system, including Converter Shelves and Fan Shelves.
• Shelf Alarm State - the highest alarm state within the shelf, including Converter Cards and -48V Input Feeds,
Fan Shelf state (if wired), and Alarm Card I 2 C to RS-485 communication processor.
OK No alarms are active – all OK
PMN Minor alarms only are active
PMJ Major – at least one major alarm is active
• Fan Shelf Alarm State – the alarm state of the connected Fan Shelves.
Each Fan Shelf has a single alarm that is active when one or more fans have failed or when Fan Shelf DC
voltage is low.
OK
No Fan Shelves have alarms are active – all OK
Minor One Fan Shelf has alarm active
Major Two Fans Shelves have alarms active
• Converter Card Alarm State - the highest alarm state of all Converter Cards within the shelf
OK No Converter alarms are active – all OK
Minor at least one Minor Converter alarms only is active
Major at least one Major Converter alarm is active
• -48V Input Feed Alarm State – the alarm state of the four -48V shelf feeds: - Table 2.
OK None
Minor One input feed Low
Major Multiple input feeds Low
6 Empty cells indicate: OK for inputs, OFF for LEDs, and non-alarm for relays.
7 Alarm relays are energized (powered) in the non-alarm state.
8 The Alarm card is redundantly powered by all four -48V input feeds.
