In the AR function, each shot can be programmed to locate anywhere in the reclose
scheme matrix. The shots are like building blocks used to design the reclose program.
The building blocks are called CBBs. All blocks are alike and have settings which give
the attempt number (columns in the matrix), the initiation or blocking signals (rows in
the matrix) and the reclose time of the shot.
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.
