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 382: 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.
9.4.4.4 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.
When the reclose time has elapsed, the CLOSE_CB output is not activated until the
following conditions are fulfilled:
