8.5.7. Synchro’ Check (25)
The ETMFC610 provides a synchronism check element. The synchronism check element is used
when both the source and load side circuit are in a live state, when the phases of the two circuits are
synchronized. If it remains in the asynchronous state for the set waiting time, it will not close even
after synchronization.
If all of the following conditions are satisfied, it is determined to be as synchronization.
The voltage of the source side and the load side must be within the synchronous detection range.
If the voltage is out of the lower limit value (Min. Volt) and the upper limit value (Max. Volt), it
is determined that the voltage of the system is not stable and it is determined as asynchronous.
The frequency on the source side and the load side must be within ± 5 Hz of the rated value.
The voltage difference between the source side and the load side must be less than or equal to
the set voltage.
The frequency difference between the source side and the load side must be less than or equal to
the set frequency difference.
The phase difference between the source side and the load side must be less than or equal to the
set
