The "GEN.TRIP-A,-B,-C" signals are transferred to the ARC function to initiate the
reclose operation of the CBs.

Acquisition of fail-safe signal provided externally
If an external relay is available to provide a fail-safe check for the internal operation of the
IED, and the user wishes to use the output of the external relay in order to enhance the
reliability of tripping further, then the PLC connection points 'ADD-FS' can be used in the Trip-
signal generation scheme. That is, the external check signal is connected at the 'ADD-FS' point.
Acquisition of external trip command
As the PLC connection point 'ADD_OPT_COM' is provided, the TRC function can accept a trip
command that is generated externally.
