If at least one of the conditions is not fulfilled within the time set with the Auto wait
time parameter, the auto-reclose 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 798: Initiation during discrimination time - AR function goes to lockout
The discrimination time starts when the close command CLOSE_CB has been given.
If a start 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.
