Warranty / Agreement Electronics International Inc. (E.I. inc.) warrants this instrument and system components to be free from defects in materials and workmanship for a period of one year from the user invoice date. Fuel Flow and Pressure Transducers are NOT covered under this warranty. They are covered by the original equipment manufacturer. Electronics International Inc.
FP-5 and FP-5L Installation Instructions 1. Important Information and Initial Check Out: A. The installer and aircraft owner must read the Warranty before starting the installation. There is information in the Warranty that may alter your decision to install this instrument. If you do not accept the terms of the Warranty, do not install this instrument. B.
2. Install the Fuel Flow Transducer: Mount the Fuel Flow Transducer using the appropriate drawing at the back of this manual. Aircraft Configuration Drawing # Page Fuel injected engine without a fuel return line from the fuel servo (most Lycomings). 1229932 or 1229931 18 or 17 Fuel injected engine with a fuel return line from the fuel servo (most Continentals). 0415941 20 Carbureted engine with a fuel pump and no fuel 1229932 or return line.
D. The flow transducer must be mounted so the wires exiting the transducer are pointing up. E. Before connecting any hoses, thoroughly clean them and insure they are free of any loose material. High air pressure may be used, however, do not allow high air pressure to pass through the flow transducer. F. When mounting a Fuel Flow Transducer make provisions for the Fuel Pressure Transducer as necessary. You may want to consider using some Fittings and Hoses shown below. Note:DO NOT EXCEED a torque of 15 ft.
5. Route the Power and Ground Wires: In the wire harness are two sets of red and black 6' wire bundles used for the fuel pressure transducer and the fuel flow transducer. Also, there are red and black 3' wires used for instrument power and ground. Route the 3' red wire in the harness to the aircraft’s 12 or 24 volt main or emergency bus as applicable via an independent circuit breaker (five amps or less). An alternate method would be to route the red lead to the bus via a one amp in-line fuse.
Any excess wires can be rolled up and tie wrapped under the instrument panel. Tie wrap these wires so they do not obstruct the freedom of travel of any controls. If you decide to cut these wires to a specific length, strip each wire and double the wires over. An extra set of connectors is provided in the kit. Double crimp each connector. Doubling the wires over and a good crimp are critical. Note: A dab or grease or two drops of oil on the red connectors will protect them for many years. 9.
11. (FP-5L Only) Connect the RS-232 Output Line: Connecting the FP-5L Output Line to a compatible GPS unit allows the GPS unit to use the fuel data transmited by the FP-5L. The FP-5L has three GPS Transmit Formats: 1. "Ot1" outputs older Shadin fuel flow data (for Arnav, King and newer Garmin GPS units); 2. "Ot2" outputs the Shadin fuel flow sentence (for Garmin and other GPS units); 3. "Ot3" outputs a modified Shadin Fuel/Airdata sentence (for UPS GPS units). The GPS unit may require some setup.
13. Install the Instrument in the Panel: Install the instrument from behind the instrument panel using 6 x 32 screws. These screws must not be any longer than 1/2". Tie wrap any loose wires as needed. Make sure the instrument and wire do not obstruct the operation of any controls. Mount the placard "Do Not Rely on Fuel Flow Instrument to Determine Fuel Levels in Tanks" on the aircraft instrument panel near the FP-5.
F. (FP-5L Only) Check the FP-5L display to read a number when the "F. to D." (Fuel to Destination) button is pushed. You may have to fly the aircraft before the GPS unit will output data. If the "F. to D." function is not working properly, use the following chart to help find your problem. FP-5L Display Comments Off The FP-5L is not receiving serial data. Check Connections and the setup of the Loran/GPS unit. ' on The FP-5L is receiving serial data but it does not have the proper protocol.
