Battery Bus Power
The battery bus receives power from the 28v dc battery bus bar or TRU 3.
The BAT BUS NORM RLY (K2) is closed and gives DC power from TRU3 to the battery bus when all of these conditions are true:
BATTERY SW ON
STANDBY POWER SW not in BAT position
TRU 3 gets more than 18v dc for more than 0.15 seconds.
When the K2 relay is closed, the BAT BUS ALT RLY (K1) must be opened.
The K1 BAT BUS ALT RLY is closed and gives power to the BATTERY BUS during these conditionBattery switch is ON and TRU 3 does not have power (less than 18v dc) for more than 0.1 seconds or
STANDBY POWER SWITCH is in the BAT position.
