During the breaker unload situation: If bit 3 »Execution of wish« is set together with
bit 0 »Wish to open the breaker«, the easYgen interprets this as an unload command.
During the breaker close situation (synchronization): If bit 3 »Execution of wish« is set
together with bit 1 »Wish to close the breaker«, the easYgen interprets this as a
synchronizing procedure.
If the 'Synchronization mode' is con󰈡gured to 'Slip frequency' and a separate slip
frequency o󰈠set is considered: bit 5 »Synchronization Mode« is "0", and bit
6 »Synchronization with separate slip frequency o󰈠set« is "1".
0 Wish to open the breaker
1 Wish to close the breaker
2 Wish is for breaker
0 = Breaker CBA
1 = Breaker CBB
3 Execution of wish The LS-5 informs that it will execute
the wish for close or open its
breaker. The execution wish isn't
active during dead bus closure or
immediately open from the breaker.
