Figure 379: Example of an auto-reclose program with a reclose scheme matrix
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:
