Therefore, at each terminal, directinputs 5 and 6 are ANDed in FlexLogic and the resulting operand configured as the permission to trip (HYB POTT RX1setting).5.9.7 Teleprotection5.9.7.1 OverviewThe relay provides 16 teleprotection inputs on communications channel 1 (numbered 1-1 through 1-16) and 16teleprotection inputs on communications channel 2 (on two-terminals two-channel and three-terminal systems only,numbered 2-1 through 2-16). The remote relay connected to channels 1 and 2 of the local relay is programmed byassigning FlexLogic operands to be sent via the selected communications channel. This allows the user to createdistributed protection and control schemes via dedicated communications channels. Some examples are directionalcomparison pilot schemes and direct transfer tripping. Note that failures of communications channels affectteleprotection functionality. The teleprotection function must be enabled to utilize the inputs.5.9.7.2 Teleprotection inputsSETTINGS INPUTS/OUTPUTS TELEPROTECTION TELEPROT INPUTS TELEPROT INPUTS TELEPROT INPUT 1-1DEFAULT: OffRange: Off, On, Latest/Off, Latest/On
