Main Distribution BUS 1

Main Distribution BUS 2
Powered By ALT 2 Powers ESS BUS's 1 & 2 ( through the MCU) Non ESS BUS Main BUS 1 Main BUS 2
What is the job of the MCU
Master Control Unit
MCU is located on the left firewall.
- controls ALT 1, ALT 2, starter, landing light, external power & power generation functions.
- Provides voltage regulation ALT 1 & ALT 2 ,
- external power reverse polarity protection,
- alternator overvoltage protection,
- Systems health annunciations
- Power is distributed to the airplane circuit panel buses through Main and Essential buses in the MCU.
The Main distribution buses are interconnected by an 80-amp fuse and a diode.
The diode prevents ALT 2 from feeding the Main distribution Bus 1. Additionally, since ALT 2 Bus voltage is slightly higher than ALT 1 voltage, bus separation is further assured
Leaning -
Best Power
Rich Of Peak
75% Power or Less
Lean until 1st Cylinder then enrichen by 75 deg F
High CHT - richen mixture (more Fuel)
Leaning
Best Economy
Lean Of Peak
65% or Less
Lean until last Cylinder then keep leaning 50 Deg F
Hgh CHT - lean further (Less Fuel)
