Hopper loads above 360 gallons

Also provided with the system are two
hopper-level warning lights: one amber

test feature and a dimming capability.
The lights are adjusted to come on at
any position (hopper level) that you may
desire by potentiometers located under
pop-off caps on the face of the analog
control unit Type FA-A. The amber light
is adjusted to come on by adjusting Pot
1 labeled set point 1, and the red light is
adjusted to come on by adjusting Pot 2
labeled set point 2.
The amber and red lights can be set at any
position you may desire. Thrush Aircraft

come on at 25 gallons, or 8 3/8" from top of
lower stop collar to bottom of floating ball,
and the red light to come on at 6 1/2
gallons, or 2 1/2" from top of lower stop
collar to bottom of floating ball.
