The settings related to CBB configuration are:
• First...Seventh reclose time
• Init signals CBB1...CBB7
• Blk signals CBB1...CBB7
• Shot number CBB1...CBB7
The reclose time defines the open and dead times, that is, the time between the
OPEN_CB and the CLOSE_CB commands. The Init signals CBBx setting defines
the initiation signals. The Blk signals CBBx setting defines the blocking signals that
are related to the CBB (rows in the matrix). The Shot number CBB1...CBB7 setting
defines which shot is related to the CBB (columns in the matrix). For example,
CBB1 settings are:
• 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
