Interaction with Control and External Triggering
With Control
The control and synchronization function are always located in a function group Circuit breaker. The control
and also the synchronization function always operate with the circuit breaker, which is linked to the function
group Circuit breaker.
As soon as the synchronization function is in the function group Circuit breaker, the circuit breaker is subject
to compulsory synchronization. If all synchronization stages are deactivated, the circuit breaker cannot be acti-
vated via the control, as no release can be generated for the closure. The circuit breaker is no longer subject to
compulsory synchronization after deletion of the synchronization function. Closure without synchronization is
then possible via the control.
If closure is to be synchronized via the control, the control automatically generates an internal signal which
starts the synchronization function. The functional sequence is described in chapter 6.4.6 Sequence of Func-
tions. After fulfilling all closing conditions, the synchronization sends a release signal to the control, which
closes the circuit breaker and then stops and synchronization function.

Figure 6-93 Interaction of the Control with 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 6.4.6 Sequence of Func-
tions).
The start is followed by the functional sequence (see chapter 6.4.6 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.
