CHAPTER 5: SETTINGS SYSTEM SETUP
D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 5-149
5
BREAKER 1 EXT ALARM — This setting selects an operand, usually an external contact input connected to a breaker alarm
reporting contact. While the selected operand is active, the BREAKER 1 TROUBLE operand is activated.
BREAKER 1 ALARM DELAY — This setting specifies the delay interval during which a disagreement of status among the three-
pole position tracking operands does not declare a pole disagreement. This allows for non-simultaneous operation of the
poles.
BREAKER 1 OPEN SEAL-IN — This setting specifies the seal-in time of the three-pole open command initiated by either the
Trip Out element or a manual open command to the circuit breaker.
MANUAL CLOSE RECAL1 TIME — This setting specifies the seal-in time of the close commands due to an operator-initiated
manual close command to the circuit breaker.
BREAKER 1 OUT OF SV — Selects an operand indicating that breaker 1 is out-of-service.
BREAKER 1 RACKED-IN — This setting selects a contact input to show whether the breaker is racked-in or racked-out. The
racked-in or racked-out status is used to indicate dynamically the status of breaker symbol, only applied in the single-line
diagram in the graphical front panel. If this setting is set to Off, the racked status is not considered.
