• First reclose time = 1.0s
• Init signals CBB1 = 7 (three lowest bits: 111000 = 7)
• Blk signals CBB1 = 16 (the fifth bit: 000010 = 16)
• Shot number CBB1 = 1
CBB2 settings are:
• Second reclose time = 10s
• Init signals CBB2 = 6 (the second and third bits: 011000 = 6)
• Blk signals CBB2 = 16 (the fifth bit: 000010 = 16)
• Shot number CBB2 = 2
CBB3 settings are:
• Third reclose time = 30s
• Init signals CBB3 = 4 (the third bit: 001000 = 4)
• Blk signals CBB3 = 16 (the fifth bit: 000010 = 16)
• Shot number CBB3 = 3
CBB4 settings are:
• Fourth reclose time = 0.5s
• Init signals CBB4 = 8 (the fourth bit: 000100 = 8)
• Blk signals CBB4 = 0 (no blocking signals related to this CBB)
• Shot number CBB4 = 1
If a shot is initiated from the INIT_1 line, only one shot is allowed before
lockout. If a shot is initiated from the INIT_3 line, three shots are allowed before
lockout.
A sequence initiation from the INIT_4 line leads to a lockout after two shots. In a
situation where the initiation is made from both the INIT_3 and INIT_4 lines, a
third shot is allowed, that is, CBB3 is allowed to start. This is called conditional
lockout. If the initiation is made from the INIT_2 and INIT_3 lines, an
immediate lockout occurs.
The INIT_5 line is used for blocking purposes. If the INIT_5 line is active
during a sequence start, the reclose attempt is blocked and the AR function goes to
lockout.
If more than one CBBs are started with the shot pointer, the CBB
with the smallest individual number is always selected. For
example, if the INIT_2 and INIT_4 lines are active for the
second shot, that is, the shot pointer is 2, CBB2 is started instead of
CBB5.
