Auto Reclosing States during manual breaker closing.
Protection Trip while Manual Close Blocking time is Timing
What happens if while the timer manual close block time is timing down the protective device gets a trip signal?
While the timer manual close block time is timing, any trip during this time period trips the breaker. The manual close
block timer does not care about that and timing continues until it times out.
After it times out, the AR-module looks at the breaker status again and sees that the breaker is open. The AR goes to
the »STANDBY« state, no autoreclosure is possible. Note: The AR Does Not go to »LOCKOUT« state!)
