Figure 6-8. Typical alarm display for three-terminal mode
The alarm display shows the code number for each alarm, a brief description of its meaning, and its status ("I"
for "inactive," or "A" for "active"). Full descriptions for each alarm are as follows:
010 - DC 9 Seconds Local Display Controller Alarm: 9 seconds has elapsed without supervisor
communications.
012 - DC No Ack 200ms Local Display Controller Alarm: No acknowledgment from Supervisor Module in
200 ms.
013 - DC 3 NAKs Local Display Controller Alarm: Three non-acknowledgments (NAKs) from Su-
pervisor Module.
014 - DC - OC No Comms Local Oscillography Controller Alarm: Display Controller lost communication
with oscillography board.
015 - DC NV RAM Fail Local Display Controller Alarm: Non-volatile RAM failure on Display Controller.
016 - Transmit Addr 1 General Alarm: Remote address 1 does not match local address or remote unit
is not responding. (Local address plus remote address must equal 4095)
017 - Transmit Addr 2 General Alarm: Remote address 2 does not match local address or remote unit
is not responding. (Local address plus remote address must equal 4095)
024 - DC DTT I Display Controller Trip Alarm: DC trip current sensed for more than 500ms
025 - DC I Sense Ckt Display Controller Trip Alarm: Current Sense circuit failure.
027 - DC 3Ph Trip I Display Controller Trip Alarm: Three-pole dc trip current sensed for more than
500ms.
030 - SV LCCT Ground Local Alarm From Supervisor Module: Local Charge Comparison Trip (calcu-
lated without active fault detector) 3I0 controller.
031 - SV LCCT A Local Alarm From Supervisor Module: Local Charge Comparison Trip (calcu-
lated without active fault detector) Phase A.
