event signals. Time stamp resolution is 1ms. Function provides also cumulative counters
for each applied reclosing events and requests.
Autorecloser function can be divided into starter, shot selector state machine, sorter and
shot blocks which operate dynamically during the reclosing cycles based into the given
settings and input signals monitoring. Autorecloser behavior can be changed dynamically
even during the cycle based into programmed reclosing scheme and active requests.
In the Figure 4.2.2-22 is presented the simplified function block diagram of the AR function.

As can be seen in the function block diagram the autorecloser is tightly dependent of the
object function block status information and configuration. Therefore in order to use
autoreclosing the controlled object has to be configured before the autoreclosing can be
used. In AQ 2xx platform the object control block takes all control of the breaker operations
which means that for example synchrocheck, breaker status monitoring etc. breaker related
functionality is not taken separately in to account in the autorecloser function. Should any
of these fail in the circuit breaker opening or closing object control function will report the
event to autorecloser function which will do corresponding action.
In addition to the previously mentioned also manual control of the breaker whether open or
close during the autoreclosing cycle will always cause reset of autorecloser. For example if
