Q

External Power

A
  • Right hand nose section
  • 3 Pins
  • Ext PWR switch connects external power to the Main Bus 1
  • EXT POWER DOOR CAS message
  • Overvoltage 30.5 Volts the external power is disconnected from the system.
  • When External power is introduced to the system, the Starter/Generators and Batteries will be disconnected from the system

Q

Generator Control Units (GCU)

A
  • Located below the baggage compartment
  • Maintains 28V DC to the aircraft busses
  • 1(2) DC GEN HOT CAS message
  • Protection for:
    • OVERVOLTAGE
    • UNDERVOLTAGE - <5V
    • FEEDER FAULT - Deferential feeder current exceeds 125 A
    • BUS FAULT - Over current > 550A - Logic will try to clear the fault within 6 seconds if unsuccessful the Starter/Generator will disconnect
    • REVERSE CURRENT - >10% of the rated load

27
Q

Power Distribution Operation

A

Discuss switchology and symbology of synoptic page

28
Q

Power Distribution Buses

A
  • Normal Flight - Generators feed the the main buses and allow the batteries to be charged.
  • Main buses power the essential and non-essential buses.
  • If both generators fail, AUX BAT feeds ESS 1 and ESS 2 MAIN BATT feeds ESS 1 & 2 and Main 1 & 2. Non-essential busses are not powered.
  • With external power connected the #1 MAIN BUS is powered and with the BUS TIE closed power is supplied to all BUSES.
  • The batteries are not charged when the external power is connected.
