DROPOUT DELAY
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.100 s
The setting is used to set the period of time for which the Breaker Fail output is sealed-in.
This timer must be coordinated with the automatic reclosing scheme of the failed
breaker, to which the Breaker Failure element sends a cancel reclosure signal. Reclosure
of a remote breaker can also be prevented by holding a transfer Trip signal on for longer
than the reclaim time.
BLOCK

Default: Off
RELAYS
Range: Do Not Operate, Operate
Default: Do Not Operate

Setpoints > Control > Breaker Failure 1 > BF1 Initiate
EXTERNAL INITIATE
Range: Off, Any operand from the list of FlexLogic operands
Default: Off
The setpoint selects the FlexLogic operand, digital input, virtual input or remote input
that initiates the Breaker Failure scheme; typically the trip signals from external devices.
The trip signals from internal protection functions may be used with the help of FlexLogic,
but for easier setting the Breaker Failure function is provided with a BF1 INITIATE submenu.
INITIATE IN1 (to IN15)
Range: Off, Any operand from the list of FlexLogic operands
Default: Ph TOC 1 OP
The setpoint selects the FlexLogic operand, digital input, virtual input or remote input
that initiates the Breaker Failure scheme; typically the trip signals from internal
protection functions.
The default setting includes the following protection functions:
Ph TOC 1 OP
Ph TOC 2 OP
Ph IOC 1 OP
Ph IOC 2 OP
Ntrl TOC 1 OP
