5.5 Connection to the Fuel Flow Sensor

1. If the aircraft is not equipped with a fuel flow source, refer to the STC covering the

installation of the fuel flow transducer on the engine.

2. When connecting to any fuel transducer, Shadin recommends using a 3 conductor, 22 gauge,

shielded wire with the shield terminated at the DigiData only.

3. Note that for single engines all fuel flow types should use left side inputs only.

4. *Install the transducers according to the engine STC. Use Drawing 4028-207 (Freq. Option)

to connect the fuel flow transducer to the DigiData.

5. *If the aircraft is equipped with a digital fuel flow transducer (P/N 680501), use Drawing

4028-207 and the STC drawing covering the installation of the fuel flow transducer in the fuel

line.

6. *If the aircraft is equipped with an existing digital fuel flow transducer (P/N 6605XX), use

Drawing 4028-207 and the STC drawing covering the interconnection of the fuel totalizer to

the existing fuel flow system.

7. Before hooking to an existing fuel system in a turbine or jet application, consult all

installation drawings contained in this manual.

8. *If the aircraft is equipped with a Analog (DC) fuel flow system, use Drawing 4005-546,

4005-548, 4028-A23, 4028-A24 and 4028-207.

9. *If the aircraft is equipped with a sine wave pickup coil type of fuel flow transducer, use

Drawing 4028-373 (Sine Wave Signal). Use the converter, SHA P/N 631201 (Drawing 4005-

642).

10. Make sure that the system is initialized with the proper K factor. Consult the DigiData

Operating Manual OM2802 and section 9.1 of this manual for setup.

* Consult section 10 of this manual for specific aircraft installation wiring drawings.
