5.7.10 TELEPROTECTION INPUTS/OUTPUTS
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 pro-
tection 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.

Setting the
TELEPROT INPUT ~~ DEFAULT
setting to “On” defaults the input to logic 1 when the channel fails. A value of “Off”
defaults the input to logic 0 when the channel fails.
The “Latest/On” and “Latest/Off” values freeze the input in case of lost communications. If the latest state is not known,
such as after relay power-up but before the first communication exchange, then the input defaults to logic 1 for “Latest/On”
and logic 0 for “Latest/Off”.
