In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, direct
inputs 5 and 6 should be ANDed in FlexLogic and the resulting operand configured as the permission to trip (
setting).

a) OVERVIEW
The relay provides sixteen teleprotection inputs on communications channel 1 (numbered 1-1 through 1-16) and sixteen
teleprotection inputs on communications channel 2 (on two-terminals two-channel and three-terminal systems only, num-
bered 2-1 through 2-16). The remote relay connected to channels 1 and 2 of the local relay is programmed by assigning
FlexLogic operands to be sent via the selected communications channel. This allows the user to create distributed protec-
tion and control schemes via dedicated communications channels. Some examples are directional comparison pilot
schemes and direct transfer tripping. It should be noted that failures of communications channels will affect teleprotection
functionality. The teleprotection function must be enabled to utilize the inputs.
