6.5 Installation of the full-authority fuel valves (one per bank)
The full-authority fuel valves are to be mounted between the fuel regulator and
carburetor fuel inlet, as close to the carburetor inlet as possible.
7. Wiring the AF900PC Controller
All wiring to the AF900PC enters the controller through three (3) conduit openings
in the bottom and connects to three (3) double row terminal strips on the bottom of
the controller main board. The terminal strips unplug from the main board for ease
of controller wiring and replacement. The main board cover plate shows the
location of the terminal strips.
Wiring for terminal strip TS1 should enter through the left conduit opening.
Wiring for terminal strip TS2 should enter through the center conduit opening.
Wiring for terminal strip TS3 should enter through the right conduit opening. This
will separate the millivolt signal levels on TS1 and TS2 from the power, output, and
relay wiring on TS3.
8. Electrical Connections
The Fuel Valves must be configured for single demand, PWM control, and low side
drive.
