Condition Indication
If the inquiry of the circuit-breaker readiness is switched on
directly before the close command through the parameter and
the maximum dead-time prolongation expires
Not ready
Blk.by CB ready sup.
Blk.by max.d.t. expiry
If the closing indication is delayed through the binary input
>Delay close cmd.
for so long until the maximum dead time
extension is exceeded before the assignment of the close
command
Not ready
Blk.by max.d.t. expiry
If an evolving fault occurs and the parameter
Response to
evolv. faults
is set to
blocks 79
Not ready
Blk. by evolving fault
If the start-signal supervision time for the operate indication
starting from the automatic reclosing function or the starting
binary input expires.
In this case, a circuit-breaker failure is assumed.
Not ready
Blk.by strtsig.superv.
If after the start of the automatic reclosing function a dead time
is already running and a blocking binary input is active, with the
following binary inputs:
>Blk. 1-pole AR
,
>Blk. 3-pole AR
,
>Blk. with 1-ph
pickup
,
>Blk. with 2-ph pickup
, >Blk. with 3-ph pickup
Not ready
Block. by binary input
If the maximum number of automatic reclosing attempts is
reached and there is a trip command within the reclaim time
Not ready
Block. by max. cycles
With operating modes with action time:
If the action times of all released automatic reclosing cycles
expire without a trip command
Not ready
Blk.by action time exp
For applications with voltage measurement and switched on
functionalities with dead-line check:
If during the dead time the required voltage criteria is not
fulfilled
Not ready
Blk.by dead-line check
For applications with voltage measurement and switched on
functionalities with dead-line check:
If during a running automatic reclosing cycle a failure of the
measuring voltage is determined.
After the completion of the automatic reclosing cycle, the
dynamic blocking becomes static blocking if there is a continued
failure of the measuring voltage.
Not ready
Blk.by loss of voltage
