2. BIO signals with regard to CB, DS, and trip signals
2-1. CHs at feeders
(1)Binary inputs
Requiring input conditions are as follows.
-DS contacts
-CBF start signals by the line-protection
-(*1)CB contacts are not required, so they are not injected.
(2)Binary output
Recommending output signals are as follows.
-BP trip signal (=DIF trip signal)
-CBF trip signal (=CBF re-trip and CBF zone-trip signal)
-CBF TR signal (=CBF transfer trip signal)

did not issue the CBF TR signal.
