In addition to these eleven display modes the FP-5L has the following pilot programmable settings (used to
set up the display and alarms): Display in Gallons, British (Imperial) Gallons, Pounds or Liters, Fuel Remaining,
Auto Calibrate the K Factor, two Low Fuel Alarms, Time to Empty Alarm, Reoccurring Fuel Used Alarm, High
and Low Pressure (i.e. PRESS.) Alarm. Also, the FP-5L has Power-Up Programmable Settings that are used to
configure the instrument for your personal preferences, aircraft and engine. Although the FP-5L is simple to
operate, the pilot programmable settings makes it a very effective and sophisticated fuel management system.
Note: After the FP-5L has been installed in an aircraft it should be programmed initially as described in the
"Power-Up Programming" section of this Manual.

1. Digital LCD Display and LED Display Mode Indicators:
If the digital LCD display backlight has been wired to be on, when the instrument is powered on (as recom-
mended), the display will be easier to see during low ambient light conditions and at night. In direct sunlight the
digital LCD display is also easy to see.
During night operation the green LED Display Mode Indicators may be too bright. If the LED Dimming
Line on the FP-5L is connected to your panel light rheostat, turning the rheostat up will dim the LEDs. If the LED
Dimming Line is connected to E.I.'s CP-1 (LED Intensity Control Pot), the Pot will control the LED intensity,
independent of other instrument lights. The two red Warning LEDs will always be displayed at full intensity.
2. Low Fuel Warning LED:
There are four pilot-programmable alarms that will blink the red Low Fuel Warning LED when violated.
The following describes how each alarm affects the Low Fuel Warning LED:
A. First Low Fuel Alarm: This alarm should be set as a reminder (example: 1/3 tank level). When the
Alarm Limit is violated the red Low Fuel Warning LED will start to blink. Pushing any button or
switch will stop the blinking and turn off the Warning LED. Also, a bar in the upper left corner of
the display will be shown when displaying "REM".

Note: In this example, the First
Low Fuel Limit was set to 12.0
Gallons. The blinking Low Fuel

limit was violated.
