Relay Systems that use the older-style electro-
mechanical relays such as ABB/Westinghouse’s
KA-4/KD-10 series of relays that have one lead that
serves the function of both start and stop. Table 2–3
would apply in this situation. Please see the
Installation Guide for details on how to install this
type of system. The “common start/stop input” box
must be checked in order for this table to be
applied. FSK channel functions are used for Direct
Transfer Tripping Systems or Line Relay Systems. If the DTT/POTT or the Unblocking-2 F selection
is set for the function, then Table 2–4 will apply.
When the FSK channel is used for both a DTT and
Line relaying channel, Table 2–5 will apply. If both
the DTT Key and LR key are present, the DTT key
will have precedence. In using the FSK channel for
Phase Comparison Relaying systems, Table 2–6
will apply.
