Note: To acknowledge a blinking LED (i.e., to stop the blinking), change the position of the Selector
Switch.

Digital Display:

On every power-up the FL-1 checks the tank calibration data for errors. If an error is found, the FL-1
displays the first error it finds and locks the FL-1 into a non-operating mode. If no errors are found,
the FL-1 will perform a power-up test, sequence the leds and display "8888" on the digital display. The
FL-1 uses an LCD display (viewable in direct sunlight), with 12 and 24 volt backlight control wires for
night operation.

Max, Min and Resolution:

Minimum fuel level for each tank: 4 gallons.
Maximum fuel level for each tank: 999 gallons.
Resolution: Programmable to 1 or 1/2 Gallon (Fuel levels below 2 gallons will be displayed as "0").

External Warning Control Line:

Grounds when the Red Warning LED is on or a yellow LED is blinking. Current should be limited to
1/10 amp.
