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 269:
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.

Sequence controller
When the
LOCKED
output is active, the AR function is in lockout. This means that new
sequences cannot be initialized, because AR is insensitive to initiation commands. It can
be released from the lockout state in the following ways:
