Technical Manual
The shot pointer starts from an initial value "1" and determines according to the settings
whether or not a certain shot is allowed to be initiated. After every shot, the shot pointer
value increases. This is carried out until a successful reclosing or lockout takes place after
a complete shot sequence containing a total of five shots.

Figure 512: Shot pointer function
Every time the shot pointer increases, the reclaim time starts. When the reclaim time ends,
the shot pointer sets to its initial value, unless no new shot is initiated. The shot pointer
increases when the reclose time elapses or at the falling edge of the INC_SHOTP signal.
When SHOT_PTR has the value six, the AR function is in a so called pre-lockout state. If
a new initiation occurs during the pre-lockout state, the AR function goes to lockout.
Therefore, a new sequence initiation during the pre-lockout state is not possible.
The AR function goes to the pre-lockout state in the following cases:
• During SOTF
• When the AR function is active, it stays in a pre-lockout state for the time defined by
the reclaim time
• When all five shots have been executed
• When the frequent operation counter limit is reached. A new sequence initiation
forces the AR function to lockout.

Reclose controller

The reclose controller calculates the reclose, discrimination and reclaim times. The
reclose time is started when the INPRO signal is activated, that is, when the sequence
starts and the activated CBB defines the reclose time.
