1.1 MECHANICAL INSTALLATION

Mechanical installation

SECTION 1

Oblò fits in a standard 3 1/8” (80 mm) cutouts. On the

1) panel it's necessary to make the cutout for the knob on the lower right hole.

The installation location must be carefully chosen since

2) Oblò contains magnetic sensors for the compass indication. Given that a location without magnetic interference can be difficult or impossible to find, it’s recommended to install the instrument in the top row of the instrument panel, to limit the interference of cables, switches and breakers that are usually found at the bottom. Do not install near any magnetic sources (wires that carry large amount of current, magnets/electromagnets, electric motors, airplane parts or metal parts that may have residual magnetic field). As a general rule keep a minimum distance of 30cm, but 60cm or more are recommended. To test if the location where you intend to install it is appropriate, turn on all the electrical loads (in particular radio and strobe lights) and move a handheld compass around the area making sure that the compass needle is stable (should not cycles back and forth) and is approximately indicating the magnetic North. Small deviations from the North can be compensated with the magnetic calibration (see chap.4.3)

During use the instrument become warm so it's

3) necessary to have some air circulation inside the instruments room, to avoid that the temperature increase over the operating limits.

Avoid placing in hot locations (for example near heater

4) vents).

Find a location where the display will always be

5) completely visible.

1.2 ELECTRICAL AND PNEUMATIC INSTALLATION

On the backpanel of the Oblò there is a 15 poles D-sub plug connector, supplied with the corresponding 15-pole receptacle, one static and one pitot port.

Use 1/8” NPT male fittings to connect the static pressure (STATIC) and the dynamic pressure (PITOT).

CAUTION: Don't blow air inside the fittings.

NOTE: Connections of pin#9-10-11-12 to a USB connector

is used for software upgrades and for datalogger function (in development).

CAUTION: The connection of the external GPS is highly

recommended to increase the accuracy of the attitude indicator. It is also required for the tracking indication and for the automatic correction of magnetic declination. If you connect a GPS that is not powered by the aircraft bus (for example battery-powered), connect together the ground of the GPS and of the Oblò. If no external GPS is available use the Flybox® GPS cod. 810010.

GENERAL WIRING HINTS:

- Take care to properly insulate any exposed wire to

avoid short circuits.

- Insert a 1-Ampere circuit breaker to the power lead (+12V).

- Use aeronautic cable for the wiring.

CAUTION: Voltage peaks on the supply line that exceeds the operating limits (20V) can damage the device.

OPTIONAL ACCESSORIES AVAILABLE:

- Ready to use wiring (ord. cod. 802000).

- GPS receiver module (ord. cod. 810010).

- USB flash drive, for eventual software upgrades.

- Backup battery system (ord.cod. 810020).

1.3 ALTITUDE SERIAL OUT FOR TRANSPONDER CONNECTION

If you use a transponder with serial input for receiving the altitude data, it can be connected to the Oblò by following this steps:

- To enable the transponder output it's required to

connect a 10Kohm resistor between pin#1 and pin#14 (whether or not it's connected the external GPS on pin#14).

- Ensure there is a shared ground between the Oblò and the transponder.

- Wire a serial transmit line, using shielded cable, from the Oblò (pin#6 of the connector) to the respective receive connection on the transponder. The serial out of the Oblò is RS232 type, refer to the transponder manual for its installation and configuration.

Connection of altitude serial out for transponder:

The Oblò does not require any configuration, the altitude data is transmitted once per second with the followig protocol:

Baud Rate Message formatting Example

9600 bps

The message contains the current pressure altitude, in feet, with a fixed reference to 1013.25mB (29.92 inches mercury). The resolution is 10 ft.

NOTE: If you use the ready-to-use wiring (ord. cod. 802000 or

802010), the 10 Kohm resistor between pin#1 and pin#14 is already fitted inside the connector housing of the wiring.

1.4 PRIMARY ACTIONS AFTER INSTALLATION

WARNING: Do not fly until you have performed at

least the actions indicated below:

1) Airspeed bar thresholds setting: It's essential to set the airspeed thresholds (bar colors) according to the V-speeds of the aircraft on which you installed the instrument, as explained in chapter 4.2, section “ASI”. Flying without correctly set this thresholds may be very dangerous because the airspeed bar indicate the colors relative to the various V-speeds incorrectly. The default factory settings are all preset to zero.

2) Magnetic calibration: The magnetic calibration after the installation of your Oblò is an essential procedure that you must perform before you fly. Not only the heading, but also the attitude indicator depends on a correct magnetic calibration. Without it there is no data stored for the magnetic sensors and the attitude indicator, that use this data also, may not work correctly. The magnetic calibration it's a simple procedure that is explained in chapter 4.3.

3) Instruments panel pitch adjust: For the proper operation of the attitude indicator it's necessary to compensate the inclination of the instruments panel regards the longitudinal axis of the aircraft, as explained in chap.4.2, “Pitch” parameter.

SERVO/S INSTALLATION :

The Flybox FX75 digital servos incorporates important safety features:

It has a reliable disengaging system: situations like severe turbolence or something other kind of anomaly will not be a problem, because the pilot can take in any case the immediate control of the plane.

When the autopilot isn't engaged, the internal gears are completely disconnected, then at difference as some servomotors the pilot will not feel no residual torque at the command stick, giving a confortable flight. In case of mechanical failure, the gear train is engineered to be reversible: the pilot can overtop the power of the brushless motor, it provides to the servomotor a further safety level.

Flybox

The output torque is electronically adjustable, and in case of forced action from the pilot on the command stick, the disengage will be without the breaking of a shear pin (unlike other servomotors on the market that use that mechanical safety system that after the break, needs a remediation action to work again).

Rev.3.7

Oblò / Oblò-A/P(Autopilot) User’s manual

Flybox

A software function disengage the autopilot if the pilot override the servo for more than 1 seconds.

It's recommended to install also the remote disengage button, to have an immediate way to disengage the autopilot even in presence of strong turbulence.

For installation instructions refer to the installation manual, which is included with each servo.

WARNING: improper installation of servos can lead to

loss of control of the aircraft, resulting in damage to the aircraft itself and injury or death of the occupants. BE SURE TO CAREFULLY FOLLOW THE INSTALLATION INSTRUCTIONS, AND CONSULT A QUALIFIED INSTALLER.

2.2 ELECTRICAL INSTALLATION

AUTOPILOT SYSTEM INSTALLATION:

• To install the autopilot system, in addition to perform the standard installation as described in chap.1.2, you must also perform the following wirings:

- Oblò ==> ACU control unit

- ACU control unit ==> servo/s

• The ACU control unit has two Molex minifit-jr connectors:

- 1 four-pole connector (here called “CON4P”).

- 1 eight-pole connector (here called “CON8P”).

Included in the kit there are the corresponding socket connectors (Molex P/N: 5556-04R for 4-poles connector and 5556-08R for 8-poles connector) and the crimp terminals (Molex P/N: 5556-TL).

Each servos is provided with a 10-poles Molex Microfit connector (Molex 43025-1000) and the corresponding crimp terminals (Molex 43030-0007).
