The operate signals from the protections are connected to the trip output contact
PO3 (X100:15-19) via the corresponding Master Trip TRPPTRC1.
TRPPTRC provides the lockout/latching function, event generation and the trip
signal duration setting. If the lockout operation mode is selected, one binary input
can be reassigned to the RST_LKOUT input of the Master Trip to enable external
reset with a push button.
