IN: DESCRIPTION:
TRIP-BLOCK Inhibits the operation of tripping logic.
TRIP-EXTTRIP Initiates the instantaneous three-phase tripping. Disabled when the function is out of oper-
ation.
TRIP-EXTL1 External tripping related to phase L1.
TRIP-EXTL2 External tripping related to phase L2.
TRIP-EXTL3 External tripping related to phase L3.
TRIP-TRSPE Information on necessary tripping in one phase. It causes instantaneous single-phase trip-
ping if some of the phase selection signals are present. If not, three-phase tripping,
delayed for 50 ms, is initiated.
TRIP-PSL1 Necessary condition for single phase trip in phase L1. Usually connected to protection
functions with phase-selective operation.
TRIP-PSL2 Necessary condition for single phase trip in phase L2. Usually connected to protective
functions with phase-selective operation.
