FL-1RA-24

FL-1RA-24

FL-1RA-24 (Fuel Level Instrument to be used in a 24 Volt System and with resistive sensors .)
FL-1CA

FL-1CA

FL-1CA (Fuel Level Instrument for use with E.I.'s capacitive sensors from 125Hz to 5KHz.)

Case Size and Weight:

2.5" x 2.5" x 3.65" depth, 2 1/4" Bezel.
10 Oz. Unit Only.

Environmental:

Meets TSO-C55

Power Requirements:

7.5 to 35 Volts, 1/10 Amp.

Analog Display:

A sets of 17 High Intensity Light Emitting Diodes (LEDs) in 210 degree arc with Intensity Control
Line available for dimming. Sequential flash test on power up.

LED Warnings:

1. 3/17 Tank Warning -

3/17 Tank Warning -

3/17 Tank Warning - If the fuel tank level reaches 3/17 of a tank, the appropriate yellow LED will

blink.

2. Low Fuel -

Low Fuel -

Low Fuel - If the left or right tank reaches 1/17 of a tank, the red LED will blink.

4. "OPEN" -

"OPEN" -

"OPEN" - If the wire to the fuel tank sensor becomes open, the analog display will show empty and

the digital display will show "OPEN."

Note:

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.
