1. DESCRIPTION

The  fuel  level  sensor  is  installed  in  the  both  left  and  right  fuel  tank  on  the  root  rib
of fuselage fuel tank. Signal from the fuel level sensor is carried via low value warning
unit  and  from  there  to  the  engine  monitoring  system  unit  Dynon  SV-EMS  220  and
from  there  to  the  Dynon  SkyView  SV-D1000.  Low  fuel  quantity  (less  than  16  litres)
is  signalized  with  the

LH FUEL RES / RH FUEL RES

red warning lamps

(Chapter 39-10).

Fuel pressure sensor and standby fuel pressure indicator are installed in the fuel
system and connected through the 3-way distributor with restrictor jets in its outlets
to the 4-way distributor. Both check the actual pressure in the fuel supply line. Signal
from the sensor is carried to the engine monitoring system unit Dynon SV-EMS 220
and from there to the Dynon SkyView SV-D1000.

Exceeding of fuel pressure limit value is signalized by red warning lamp

EMS

on the instrument panel (Chapter 39-10).

The fuel flow transducer is located on the engine mount top. The electrically operated
fuel flow transducer transmits fuel flow rate data to the engine monitoring system unit
Dynon EMS 220 and from there to the Dynon SkyView SV-D1000.

DRAINING ALL FUEL FROM THE FUEL SYSTEM IS NOT
POSSIBLE, BE CAREFUL DURING DISASSEMBLING THE FUEL
SYSTEM.

NOTE

Described is left side. The right side is mirrored.

(1) Fuel level sensor removal:

Make sure that the

IGNITION

switches are set to

OFF

Remove engine cowlings (Chapter 71-10).

Disconnect negative terminal of battery (Chapter 24-30).

Electrically ground the aircraft (use the exhaust pipe outlet)

to the grounding point.

Drain fuel tanks (Chapter 12-10).

Inside of the cockpit to the left and right of the wing pin remove round
cover (3, Fig. 06-4, Chapter 06-00).

Disconnect connectors (5, Fig. 28-9).

Unscrew the bolts (3) with washers (4).

Pull out fuel float LH/RH (1) with seal (2).

INDICATING

FUEL

(2) Fuel level sensor installation:

Make sure that the

IGNITION

switches are set to

OFF

In cockpit on side, put fuel float (1, Fig. 28-9) with seal (2).

Put washers (4), tighten the bolts (3) secured with Loctite 577.

Connect connectors (5).

Check if sensor is firmly secured and sealed.

Install round cover (3, Fig. 06-4) from inner side of the cockpit
to the left and right side near main wing pin.

Connect negative terminal of the battery (Chapter 24-30).

Install engine cowlings (Chapter 71-10).

Remove the ground cable from the aircraft.

Replenish the fuel system (Chapter 12-10).

Carry out engine ground test; check fuel system for leaks and fuel

system indication.

(3) Adjustment / Test

– calibration and check of a correct function

of the measurement system and indication of fuel quantity

Carry out this procedure on the aircraft with completely finished fuel
installation.

Perform the procedure in a suitable and exactly defined space. In this space
and

in its vicinity don´t carry out, in the course of the calibration, any other

work than the work necessary for performing the calibration.

As working and procedure medium for this calibration, use gasoline Natural
95 or aviation gasoline Avgas 100LL.

During  this  procedure,  perform  the  tank  filling  with  fuel  by  means
of  the  calibration  device  or  the  calibration  vessel  so  that  it  is  possible
to  determine  a  precise  quantity  of  added  fuel.  For  the  same  reason,  use
the  calibration  device  or  the  calibration  vessel  also  when  draining  fuel
from  the  tank.  When  handling  fuel,  use  the  clothing  that  doesn´t  contain
artificial clothes.

WARNING

UNAUTHORIZED ENTRY TO THE SYSTEM SETTINGS AND NON-
OBSERVANCE OF THE DEFINED CALIBRATION PROCEDURES
MAY CAUSE AN INCORRECT FUNCTIONALITY OR A TOTAL
FAILURE OF THE WHOLE SKYVIEW SYSTEM!

NOTE

FUEL

Level the aircraft (Chapter 08-10).

Electrically ground the aircraft (use the exhaust pipe of the aircraft)

to the grounding point.

Check whether appropriate wing tank is empty; otherwise, drain

the fuel (Chapter 12-10).

Connect the aircraft to the external power source.

Check whether the appropriate drain valve is closed and remove

the tank filler cap.

Enter the SETUP MENU of the appropriate SV-D1000 Display.

By turning the rotary switch, select HARDWARE CALIBRATION.

Move the rotary switch to the right and select EMS CALIBRATION.

By turning the rotary switch, select the calibrated tank

– FUEL TANK

1 or 2 (LEFT or RIGHT) and then move the rotary switch to the right.

If you want to edit the calibration, select EDIT; if you want to do
a recalibration, select RECAL.

EDIT

editing of the calibrated values in the table

– for fine tuning.

In "POINT 1" for empty tank "VALUE (LTR) = 0.0" set the value

of "VOLTS" according to the actual value VOLTAGE SENSOR
(top right corner of the screen). Save the set value using the SAVE
DONE buttons.

Add to the tank exactly 5 liters of the fuel. Wave with the fuselage and
wait for spill and stabilization of fuel level in the tank

– the aircraft must

be at rest.

Reselect by the cursor value in "POINT 2" and press ADJUST.

In "POINT 2" for tank "VALUE (LTR) = 5.0" set the value of "VOLTS"

according to the actual value VOLTAGE SENSOR (top right corner
of the screen). Save the set value using the SAVE DONE buttons.

Repeat procedure in accordance with points (l), (m) and (n)

up to 45 liters.

To calibrate opposite fuel tank, repeat steps (i) to (o).

Finish and save the calibration by the DONE button. Exit menu

by the EXIT button.

Disconnect external power source and grounding from the exhaust
pipe.
