ORDINAL SIGNAL NAME ELEMENT NAME
DESCRIPTION
456
Recon Interlock
DDB_RECONFIGURATION_INTERLOCK
This must be energized (along with DDB 455 - inhibit C Diff) at the time that a relay configuration is changed from 3 ended to 2 ended
scheme. This usually should be driven from a 52-B contact of the CB connected to the line end that is taken out of service
459
Test Mode
DDB_TEST_MODE
Commissioning tests - automatically places relay in test mode
460
103 CommandBlock
DDB_COMMAND_BLOCKING
For IEC-870-5-103 protocol only, used for "Command Blocking" (relay ignores SCADA commands)
461
103 MonitorBlock
DDB_MONITOR_BLOCKING
For IEC-870-5-103 protocol only, used for "Monitor Blocking" (relay is quiet - issues no messages via SCADA port)
