Figure 8-73 Connection of the AREC to the Synchronization Function
With External Control
You have the option of controlling the synchronization function externally via binary input signals. This can be
done as follows:
•
Edge-controlled
•
Via the signals >Start syn. process and >Stop syn. process
•
State-controlled, via the signal >Start / stop syn.proc. (see also chapter 8.4.6 Sequence of Func-
tions).
The start is followed by the functional sequence (see chapter 8.4.6 Sequence of Functions). If the conditions
are fulfilled, the output signal Release close cmd. is issued. The switched object QAx of the function
group Circuit breaker is not closed. The output signal Release close cmd. must be explicitly assigned to
the binary output in order to close the circuit breaker.
