5 SETTINGS 5.3 SYSTEM SETUP
5
The switch element has direct hard-coded connections to IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each switch, using either CSWI or XSWI IEC 61850 logical nodes. IEC 61850 select-
before-operate functionality, local/remote switch functionality along with a blocking open/close commands are provided.
Note that IEC 61850 commands are event-driven and dwell time for these is one protection pass only. If you want to main-
tain close/open command for a certain time, do so either on the contact outputs using the "Seal-in" setting or in FlexLogic.

FLEXCURVE A(D)
FlexCurves A through D have settings for entering times to reset and operate at the following pickup levels: 0.00 to 0.98
and 1.03 to 20.00. This data is converted into two continuous curves by linear interpolation between data points. To enter a
custom FlexCurve, enter the reset and operate times (using the VALUE keys) for each selected pickup point (using the
MESSAGE UP/DOWN keys) for the desired protection curve (A, B, C, or D).
