BCB control and synchronizing
If the system is equipped with BCB the BCB is controlled by the Bank controller. There is a set of control
outputs for various types of the breaker or contactor: BCB close/open, BCB ON coil, BCB OFF coil, BCB UV
coil. Breaker feedback signal is to be connected to the binary input with logical function BCB feedback. If this
logical function is not configured on any binary input the bank controller assumes BCB is not used. See the
chapter Installation for information about proper wiring of the site with or without BCB.
