1 Introduction

With it's innovative i eas an mo ern technology the ALPHAMFD offers a complete

system for flight an engine-management for ultralight/microlight pilots. Important

information for navigation an engine control are easily rea able, presente on an

integrate Liqui Crystal Display.

The ALPHAMFD was carefully esigne to be extremely reliable, safe an

maintenance free. A self-test on power-on, etection an warning of faulty sen ers

an the au io alarm through the Intercom make the ALPHAMFD an extremely

reliable an safe flight information system.

Using mo ern processors an a flash-memory, the software of the ALPHAMFD can

be up ate any time an thus being up ate to the latest software version without

hassle an cost. The ALPHAMFD is a soun long-term investment.

In or er to avoi information overloa of the pilot, only the most important information

like spee , vario, altitu e, RPM, EGT, CHT or water/oil-temperature, flight time, real-

time, fuel state an consumption, are permanently isplaye . More information can be

calle up by pressing only a few keys, e.g. flight log or engine hours, etc.

The innovative LC- isplay is easy to rea in any light con itions, all rea -outs are

esigne following ergonomic rules.

Because of the logical an clearly structure menus, the ALPHAMFD is very easy to

operate. You basically only have to switch on the instrument an off you go. However

we strongly recommen you rea the operation manual carefully to make the best out

of the many functions the ALPHAMFD offers.

We wish you many fantastic an safe flights with your new ALPHAMFD.

Note:

The operating instructions contain many important information which are necessary for

a safe operation of the ALPHA

ALPHAALPHA

ALPHAMFD. Please rea the instructions carefully! If you o

not un erstan something, you must not use the ALPHA

ALPHAALPHA

ALPHAMFD. If you have questions,

please contact the nearest

BRÄUNIGER

Service Centre or

BRÄUNIGER

irectly.

WARNING! This icon esignates important safety information in the

operating manual. Please rea carefully!

2 Mounting and Connections

2.1 Warning

The ALPHA

ALPHAALPHA

ALPHAMFD is not certifie by LBA/FAA/JAA as this is not require for Ultralights

in most countries. However, if such a certification will be require in the future, the

certification will be complete . The instrument is esigne following the most state of

the art technologies an it is extensively teste following the proce ures of LBA!

Although the ALPHA

ALPHAALPHA

ALPHAMFD is an electronic an very precise instrument, incorrect

values can be shown, mistakes in operation can be ma e an shown values can be

misinterprete . By operating the ALPHA

ALPHAALPHA

ALPHAMFD, the user confirms that he knows about

these angers an he is accepting responsibility for any possible risks.

In or er to minimize these risks, the operating instructions MUST be rea carefully. If

you have questions, please contact

BRÄUNIGER

or a

BRÄUNIGER

Service Centre.

2.2 Mounting into Cockpit

It is very easy to mount the ALPHAMFD in your cockpit. You only nee a little skill,

no special tools are require .

Dimensions of ALPHAMFD:

Front 220 x 145 mm

Cockpit Cut-out 137 x 194 mm

Drillings 207 x 87 mm, 32 mm from

bottom an 26 from the top.

All measurements in mm

Total weight only approx. 850 grs!

WARNING:

The following points must be carefully observed:

• Protect the unit from too high or too low temperatures. The unit works reliably in

a temperature range of -15°C to 50° Ceslsius.

• Protect the unit from excessive shock or vibrations. It might be necessary to

mount the unit with suitable shock absorbing materials.

• Protect the unit from irt an moisture an all kin s of oils an gasoline.

• The isplay must be easy to rea , protect the unit from glare an ensure a goo

fiel of view.

• Mount instrument as far away from ra io / transpon er antennae as possible.

All points must be observed for longevity and reliability!

2.3 Electrical Connections

If you have never before installe electrical instruments an you are not exactly sure

what to o, please ask someone who has experience to help you with the installation.

When working with sen ers, please han le carefully, as they are sensitive electronic

parts.

Only use high-quality cables (highly flexible, stran e an shiel e ) an connectors.

Check that your cables run untangle an clean. Disconnect the aircraft battery before

working on electrical components!

Ni-Cr-Ni temperature sen ers require special cables which are supplie with the

sen ers!

WARNING:

All wires shoul be protecte by small metal terminals to ensure a

lasting an safe connection to the ALPHAMFD. All cables an the Pitot tube

shoul be secure against pull. There is a special mounting bracket on the rear

of the ALPHA

ALPHAALPHA

ALPHAMFD for securing against pull.

When mounting the senders the following points must be observed:

• Protect the sen er lea s against high temperatures.

• Protect the sen er lea s from excessive vibration. However, a certain amount of

movement must be allowe .

• The sen er lea s must not be sharply bent or abra e .

• The threa s of EGT, CHT, water- an oil temp sen ers must be treate with

Loctite Anti Seize (or a similar agent) to ensure trouble-free unscrewing.

Type K temperature senders NiCrNi) MUST be exten e with specially

compensate extension lea s. If the lea s of the sen ers are too short an must be

exten e , the special Type K extension lea s an Type K plug an sockets MUST be

use . These lea s are available from

BRÄUNIGER

Type Pt100 temperature senders o not nee specially compensate extension

lea s but can be exten e with stan ar copper lea s.

Please observe, that the ALPHA

ALPHAALPHA

ALPHAMFD is equipped with two different types of

temperature ports: Type K and Pt100. These ports can ONLY be used with

the respective type of sender.

Please follow the technical information of the sen ers you are using.

NOTE:

BRÄUNIGER

provi es complete cable looms an sen er kits as an option for

some popular engines. With these connection kits, it is even easier to connect the

ALPHAMFD.

2.3.1 Switch-Off unuse Temperature Ports

The ALPHA

ALPHAALPHA

ALPHAMFD has six ifferent ports where temperature sen ers can be connecte

(Two Type Pt100 an four Type K). Because with some engine configurations some

ports are not use , they can be switche off.

Because of their technical characteristics, temperature ports still show temperatures

even when no sen ers are attache , an these temperatures are of course "nonsense".

Therefore the ports can be switche off an "nonsense" values are suppresse .

Switching-off ports is one in SET-Mo es 31 through 37.

35 CHT 1 Use CHT 1 Port YES / NO

36 CHT 2 Use CHT 2 Port YES / NO

37 Fuel flow Use Fuel Port YES / NO

Attention: Under set mode 37 it’s up from version 4.04 possible to

deactivate the fuel port. This may be helpful for trikes where the gas tank is

visible close to the pilot, or fuel systems with high flow back systems where

the flow sensor can’t work!

Note: The factory setting is all temperature ports ON!

WARNING: Make sure only unused temperature ports are switche

off! If a

use temperature port with a connecte sen er is acci entally switche off,

the temperature is not displayed and also the alarm function is

inoperative!

2.4 Mounting Fuel Flow Sender

2.4.1 General Notes

The fuel capacity in icator of the ALPHA

ALPHAALPHA

ALPHAMFD works with a special fuel flow sen er.

We recommen only to use the sen er supplie by

BRÄUNIGER

, because other

sen ers are not a apte to the ALPHA

ALPHAALPHA

ALPHAMFD an precise function can not be

guarantee . The fuel flow sen ers transmits pluses accor ing to the actual fuel

consumption to the ALPHA

ALPHAALPHA

ALPHAMFD. These pulses are a e up to a fuel capacity

in icator. The sen er can be use with all kin s of fuel.
