SECTION 1

1.1 PRIMARY ACTIONS AFTER INSTALLATION

WARNING: Do not fly until you have performed at least

the actions indicated below:

1 - Select the engine type: the first parameter to setup is the
engine selection, because it reset all the parameters to the
default value. The engine selection can be made by entering in

the Main menu → Settings → Global Settings → Aircraft as

explained in chap.1.3.5.

2 - Tank level sensors: (if connected). It's indispensable to
perform the calibration for all the tank level sensors connected
to the Vigilus. Without performing calibration and settings no
indication will be furnished.
It is responsibility of the user to check during the first flights
and over time the goodness of the calibration and therefore
the instrument indications.
The verification can be done in any moment, for example b y
simply checking the quantity put to fill the tank: if you k n o w
that the tank filled contain 40 liters and the Vigilus i n d i c a t e
as remaining quantity 10.0 liter, you know that to fill the tank
you must put approximately 30 liters. Of course keeping in
mind that in ground the indications will be different that in
flight because of the flight's attitude. This problem is present
also in the traditional analog gauge indicators, but is more
difficult to detect because of the non-numeric indication.
Another verification is, in case of low remaining quantity (i.e.
4~5 liters), drain and measure it.

Primary actions after installation

3 - Fuel computer: (if installed). If it's installed the fuel flow
transducer, BEFORE rely on informations provided by the fuel
computer section you must:

- Verify that the K-factor set in the Vigilus is pertinent to the
installed fuel flow transducer (for the Flybox® TFTHP is 416400).

- Execute the fuel flow transducer calibration as explained in
chapter 1.4. Without calibration the fuel computer
informations may be wrong, even if the nominal K-factor is
correct for the fuel flow transducer used.
After calibration, the K-factor should have been calculated
automatically and at best for every single installation. You must
still check for some time if the remaining quantity indicated are
reliable compared to the refuelling performed. For example, if
the instrument indicate a remaining quantity of 35 liters and you
know that the tanks capacity is 80 liters, filling the tanks should
require approximately 45 liters; in case of much difference redo
the calibration.
Consider also that, during use, little errors accumulate and if
you never fill the tanks you never “reset” all these errors.

To increase accuracy in the fuel flow measurement you must
calibrate the transducer by following this steps.

NOTE: it's recommended to perform the calibration right after
installing the Vigilus+Remote module and repeat it once a year.

1- With the aircraft in level attitude, fill the tank/s of fuel; note
that in the step #4 it's required to refill the tank/s at the
exact level reached here.

2- Turn-on the Vigilus and select “FILLED” when asked for
the fuel quantity.

3- Burn at least 3/4 of fuel in the tank/s: a greater amount of
burned fuel will increase the accuracy, and you can do
this step in more flights: at the start of each flights you
must not add fuel in the tank/s and you must select “NO

REFUEL” when asked after turning on the Vigilus.

4- Fill the tank/s with the exact same level reached in the

step #1, accurately measuring the quantity of fuel added
in the tank/s.

5- Turn on the Vigilus and select “NO REFUEL” (even

though you have refilled it’s required to select “NO

REFUEL”).

6- Enter in the Main menu → Settings → Fuel Computer →

Calibration; the following screen will appears:

7- Now you must insert in the “FUEL FILLED” the exact
quantity of fuel that you have added and measured in step
#4; probably it doesn't correspond exactly to the “FUEL
USED” because this is the measurement from the
transducer not yet calibrated and it’s showed for reference
only. To insert the value rotate the knob and press
“ENTER” to confirm. To exit without saving, press “ESC”.

8- When you confirm by pressing “ENTER” the display will
briefly shows the newly calculated K-factor and return to
the Fuel computer menu. The transducer is now
calibrated and the K-factor is automatically stored in
memory; you can safely exit the setup menu or turn off the
Vigilus.

NOTE: it's recommended to annotate the K-factor value
so that if you inadvertently modify it it's possible to
manually reenter the value without doing again the
calibration (however the fuel flow transducer calibration
may be repeated in any moment).

Before using the fuel level indications it's necessary to calibrate
all the aircraft fuel tanks by following the procedure explained
in this chapter.

The calibration is divided in more calibration steps, in each step
you will fill the tanks with predetermined fuel quantity; the
calibration ends when the tank is completely filled.

The parameters available in the calibration menu are:

● Cal Steps: With this parameter it's possible to choose the fuel
quantity to add at each calibration step. Choose a proper value
considering the tanks capacity and how many calibration steps
you want to execute.
For example with a 40 liters tank and “Calibration fuel step”

set to 2 it's required 40 / 2 = 20 calibration steps. Consider
also that the maximum number of calibration steps that is
possible to store in memory for every tank is 50.

The “Cal. steps” parameter is used for all the tanks

calibrations, don’t modify it once you have choosed a value
(range:1~100 lt, default=2 lt).

● mV Steps: Minimum thresold to detect fuel sensor movements
(default = 20, don't modify this value).

● DRES Filter: Filter for DRES sensors only. Not used for the
other sensor types.

Fuel level sensors calibration

NOTE: A common problem for many fuel level sensors is that

they can't completely measure the tank capacity, so one or both
of this conditions can occur (see also “Fuel level sensors”
section on chap.2.4 of the installation manual):

- As you add fuel to an empty tank it takes a certain amount
of fuel before the fuel sensor start to move from the
bottom.

- As you drain fuel to a filled tank it takes a certain amount
of fuel before the fuel sensor start to move from the top.

If one of this conditions occurs during the calibration, the Vigilus
notice that the fuel sensor doesn't produce an electrical change
and ask the user if fuel was really already added for that
calibration step:

If you are sure to have already added the fuel click on “YES”
otherwise click on “NO” to go back to the previous calibration
step.

Please note that the amount of fuel that is not measurable,
it will not be counted, so for example if your tank have a

capacity of 40 liters but only 30 is measurable by the fuel level
sensor, after the calibration you will see 30 liters when the tank
is full.

1.5.1 FUEL LEVEL SENSORS CHECKINGS

To configure correctly the fuel level indicators, you need to know
what type of fuel level sensors are installed in your aicraft. The
resistive sensors can be of two types:

● Sensors that increase resistance as the fuel level increase

● Sensors that decrease resistance as the fuel level increase

If you don't know what type of resistive sensors are installed in
your aircraft, follow this procedure:

- Empty the tank that you want to check.

- On the Vigilus enter in the calibration for that tank (Main

menu → Instruments → Fuel L → Calibrations →

Left/Right/Main Tank ).

- From the screen that appear click on “START” button

- Annotate the numerical value (mV):

- Add a certain amount of fuel in the tank and check if the
numerical indication increase or decrease: if increase then
the sensors installed increase the resistance as you add
fuel (RES+), if decrease the sensors decrease the
resistance as you add fuel (RES-).

To exit from the calibration screen click on “ABORT”.
Repeat the procedure for any other unknown sensors installed.

● Status indicator: This is a useful indicator that you should
check before takeoff.
When the essential measurements are not in a safe area the

indicator shows “WARMUP” in red background; the
measurements taken in consideration are the oil pressure
(must be in green zone), the oil temperature (must be warmer
than “Clearance” parameter), the fuel pressure (must be in
green zone), the CAT (must be in green zone) and all the
CHTs (must be in green zone).

When all the measures becomes in its safe zone the indicator

change state to “READY” in green background, that
automatically disappear 30 seconds after take-off.

● Flight time: The flight timer starts automatically when the
engine meets or exceeds for 30 seconds the value set in the
“Flight” parameter (see chap.1.3.4, section “RPM setup menu”)
and it stops automatically when the engine is turned off (0000
RPM).

VARIANT FOR ROTAX 912iS:

The engine page for the Rotax 912iS version is slightly different
from the aspirated version; the differences are:

1 - WT (Water temperature) instead of CHT (Cylinder head
temperature): 912iS have only one sensor for the water/coolant
temperature.

2 - MT (Manifold temperature) instead of CAT (carburetor
temperature).

3 - TP: Throttle position 0~100%

4 - The STATUS INDICATOR became a smaller circular version
to save space for the throttle position gauge. The function of
the status indicator remain the same:
When the essential measurements are not in a safe area the
indicator shows “WU” in red background; the measurements
taken in consideration are the oil pressure (must be in green
zone), the oil temperature (must be warmer than “Clearance”
parameter), the fuel pressure (must be in green zone), the MT
(must be in green zone) and the WT (must be in green zone).
When all the measures becomes in its safe zone the indicator
change state to “RD” in green background, that automatically
disappear 30 seconds after take-off.

5 - ECU STATUS: This status indicate if the Vigilus is
communicating properly with the two ECUs (A and B) of the
Rotax 912iS engine.
If the communication is ok with both A and B ECUs the two
indications are in green [A B].
If the communication is missing with one of the ECUs the
relative indication is in red ( for example [A B] or [A B] ).

● Fuel levels section:

The fuel level indications are obtained by reading the fuel level
sensors installed in your aircraft and connected to the remote
module of the Vigilus. The indications are approximated, do not
solely rely on the Vigilus indications to determine the fuel
available in the tanks, but always refer to primary instrument
installed in your aircraft.

Before using the fuel llevels section you must be sure to have
already set the following parameters:

- Set the unit of measure: USgallons or liters (set this before all
the other parameters). See parameter “Unit” on menu Settings

→ Instruments → Fuel L → Tanks.

Left/Right/Main Tank).

- Execute the calibration for each used tanks (see chap.1.5).

● Fuel Computer section:

Before using the fuel computer section you must be sure to have
already set the following parameters:

- Set the unit of measure: USgallons or liters (set this before all
the other parameters). See parameter “Fuel unit” on menu

Settings → Fuel Computer.

- Set the unit of measure: kilometers or nautical miles. See

parameter “Space unit” on menu Settings → Fuel Computer.

- Set the total tank/s capacity. See parameter “Tank Cap.” on

menu Settings → Fuel Computer.

- Set the K-factor. The K-factor of a fuel flow transducer is the
number of electric pulses for 1 gallon of fuel consumption (if you
have K-factor in liters you must multiply this value by 3.78 before
set k-factor in the Vigilus). If you use Flybox® TFTHP fuel flow
transducer, set the k-factor to 416400.
It's recommended also to execute the K-factor calibration as
soon as possible to have the maximum accuracy (refer to
chapter 1.4 “Fuel flow transducer calibration”).

Everytime after powering-on, the Vigilus ask if you have
refuelled the tank; you must choose one of the 3 options
available (rotate the knob to select and press to confirm):

VIGILUS - Operating manual

NO REFUEL: Select this option if you have not refuelled the
tank.
ADD FUEL: Select this option if you have added fuel to the tank
(on the next screen that appears you can insert the exact
amount of fuel added).
FILLED: Select this option if you have filled the tank; the display
will show the quantity that has been added to reach the full level.
Before using this option you must have already set the tank/s
capacity in the fuel computer setup.
If you press “ESC” pushbuttons no change are made, but the
next time that you reach the fuel management page it ask again
until you choose one of the three options.

NOTE: If you need to correct a wrong fuel quantity add, select
“ADD FUEL” and insert a negative value.

Now the fuel computer is ready to operate; the available
indications are:

● FUEL FLOW: According to the selected unit of measure the
flow is indicated in liters per hour (Lt/h) or gallons per hour (Gl/h).

● REMAINING FUEL: Display the fuel remaining in the tank/s.
According to the selected unit of measure the quantity is
indicated in liters (Lt) or gallons (Gal).
WARNING: The remaining fuel displayed here is not a

measurement of the fuel in the tank, but it is calculated from
the initial quantity entered by the user and the burned quantity
measured by the fuel flow transducer (or measured by the
Rotax ECU for the 912iS version).

● ENDURANCE: Display the time to empty, calculated
considering the fuel remaining and the actual fuel flow.
If it is not possible to calculate the time to empty (for example

when the engine is not running) the display shows --:--

● RANGE: Display the range calculated considering the fuel
remaining, the actual fuel flow and the ground speed furnished
by the GPS.

If the display shows “NO GPS!” it means that the GPS is

disabled (see parameter “GPS Enabled” on menu Settings →

Fuel Computer). If the display shows “WAITING GPS RMC” it
means that the GPS is enabled but not connected, turned off
or it don't have the fix.

If it is not possible to calculate the range (for example when

the engine is not running) the display shows --:--

● RESERVE: Display the fuel remaining at destination; the
destination is intended as the approaching GPS waypoint.
If the number is negative it means that there is not enough

fuel to reach the destination.

To enable this indication you must connect an external GPS

and enable the “RMB” sentence on it; you must also set to

“YES” the parameter “GPS Enabled” on menu Settings →

Fuel Computer.

If the display shows “NO GPS!” it means that the GPS is

disabled (see parameter “GPS Enabled” on menu Settings →

Fuel Computer). If the display shows “WAITING GPS RMB” it
means that the GPS is enabled but not connected, turned off
or it don't have the fix.

Vigilus continuously monitor all the sensors and when a
measurement exceed its setpoint the corresponding alarm is
activated (if enabled).

An alarm condition is indicated in this ways:

● A red flashing message appears on the bottom of the
display, as in this example:

● One of the four programmable outputs of the remote module
is activated (if enabled).

● Vocal alert on the audio output is activated (if enabled).

To reset any alarm condition press or rotate the knob or press
a button; in case of multiple alarms the alarm pages is presented
in sequence.

The possible alarm conditions are:

● “HIGH BATTERY VOLTAGE!”

Another type of alarms is the sensor alarms, that occur when
the Vigilus cannot find a sensor needed for a measurement:
if this happen you should check possible damage to the wiring
or to the sensor itself.

The sensors taken in consideration are only those enabled in
all the instruments submenu (refer to chap. 1.3.4 “Instruments
menu”). For this reason you must ensure to have enabled only
those sensors installed in your aircraft and let disabled all the
rest to avoid false alarms.

The possible sensor alarms are:

● "EGT1~6 SENSOR ERROR”

● "CHT1~6 SENSOR ERROR”

● "FUEL PRESSURE SENSOR ERROR!"

● "OIL PRESSURE SENSOR ERROR!"

● "OIL TEMPERATURE SENSOR ERROR!"

● "CAT SENSOR ERROR!"

● "OAT SENSOR ERROR!"

The datalogger is a useful data recording tool that permits later
viewing in both graphical or numerical representation. It also
allow the download of the data in a USB flash drive.
Data are organized in separate recording sessions, each time
the engine is started a new recording session will be initiated.
The memory can store 100 hours of data, with a sample rate of
1 second. Older data are automatically erased to make room
for the new ones.
The datalogger menu shows a list of flights, sorted by date (the
most recent flight is the first on the list). The “Time” column
indicate the start of the flight while the “Fl. Time” column indicate
the fligh time.
NOTE: the date and time indications is read from an external
GPS, if connected; if no GPS is connected to the Vigilus, these
indications will not be available.
