When the reclose time has elapsed, the
CLOSE_CB
output is not activated until the
following conditions are fulfilled:
•
The
SYNC
input must be TRUE if the particular CBB requires information about the
synchronism
•
All AR initiation inputs that are defined protection lines (using the
Control line
setting) are inactive
•
The circuit breaker is open
•
The circuit breaker is ready for the close command, that is, the
CB_READY
input is
TRUE. This is indicated by active
READY
output.
If at least one of the conditions is not fulfilled within the time set with the
Auto wait time
parameter, the autoreclose sequence is locked.
The synchronism requirement for the CBBs can be defined with the
Synchronisation set
setting, which is a bit mask. The lowest bit in the
Synchronisation set
setting is related to
CBB1 and the highest bit to CBB7. For example, if the setting is set to "1", only CBB1
requires synchronism. If the setting is it set to "7", CBB1, CBB2 and CBB3 require the
SYNC
input to be TRUE before the reclosing command can be given.

Figure 513:
Initiation during discrimination time - AR function goes to lockout
The discrimination time starts when the close command
CLOSE_CB
has been given. If a
pickup input is activated before the discrimination time has elapsed, the AR function goes
to lockout. The default value for each discrimination time is zero. The discrimination time
can be adjusted with the
Dsr time shot 1…4
parameter.
