Ex CLOSE/OPEN
If the switchgear should be opened or closed by an external signal, the User can assign one signal that will trigger the
CLOSE and one signal that will trigger the OPEN command (e.g. digital inputs or output signals of the Logics). An
OPEN command has priority. CLOSE commands are slope oriented, OPEN commands are level oriented.
Synchronised Switching*
*=availability depends on ordered device type
Before a switchgear may connect two mains sections, synchronism of these sections must be assured.
In the menu [Synchronous Switching] the parameter »Synchronism« defines which signal indicates synchronism.
If the synchronism condition shall be evaluated by the internal Synch-Check module the signal
»Sync. Ready to Close«
(release by synch-check module) has to be assigned. Alternatively a digital input or a logic output can be assigned.
In the synchronisation mode “Generator-to-System” additionally the synchronism request has to be assigned in the
menu [Protection Para\Global Prot Para\Sync].
If a synchronism signal is assigned, the switching command will only be executed, when the synchronism signal will
become true within the maximum supervision time »
t-MaxSyncSuperv«. This supervision time will be started with the
issued CLOSE command. If no synchronism signal has been assigned, the synchronism release is permanently.
