Disconnect Switch Control - GE T60 Instruction Manual

SYSTEM SETUP
5
The breaker element has direct hard-coded connections to the IEC 61850 model as shown in the logic diagram. This allows
remote open/close operation of each breaker, using either CSWI or XCBR IEC 61850 logical nodes. IEC 61850 select-before-
operate functionality, local/remote switch functionality, along with blocking of open/close commands are provided. Note
that the dwell time for the IEC 61850 trip and close commands shown is one protection pass only. To maintain the close/
open command for a certain time, do so by setting the seal-in timers
, on the contact outputs using the "Seal-in" setting, in the Trip Output element, and/or in FlexLogic.
