  • Page 4: Introduction

    The innovative LC-display is easy to read in any light conditions, all read-outs are designed following ergonomic rules. Because of the logical and clearly structured menus, the ALPHAMFD is very easy to operate. You basically only have to switch on the instrument and off you go. However we strongly recommend you read the operation manual carefully to make the best out of the many functions the ALPHAMFD offers.

    Service Centre. 2.2 Mounting into Cockpit It is very easy to mount the ALPHAMFD in your cockpit. You only need a little skill, no special tools are required. Dimensions of ALPHAMFD: Front 220 x 145 mm...

  • Page 6: Electrical Connections

    WARNING: All wires should be protected by small metal terminals to ensure a lasting and safe connection to the ALPHAMFD. All cables and the Pitot tube should be secured against pull. There is a special mounting bracket on the rear of the ALPHA ALPHAMFD for securing against pull.

  • Page 7: Switch-Off Unused Temperature Ports

    2.3.1 Switch-Off unused Temperature Ports The ALPHA ALPHA ALPHAMFD has six different ports where temperature senders can be connected ALPHA (Two Type Pt100 and four Type K). Because with some engine configurations some ports are not used, they can be switched off.

    ALPHAMFD and precise function can not be guaranteed. The fuel flow senders transmits pluses according to the actual fuel consumption to the ALPHA ALPHA ALPHAMFD. These pulses are added up to a fuel capacity ALPHA indicator. The sender can be used with all kinds of fuel.

  • Page 11: Important Safety Notes

    BRÄUNIGER fuel flow sender is looped in the fuel line between filter and engine. Make sure all connections of fuel line are leak proof and secure. Secure all line connections with suitable parts, e.g. hose clamps. The fuel flow sender is designed in such a way, that even when the sensor wheel is blocked, there is always enough fuel throughput to keep the engine running.

    Next the instrument goes into CHECK-Mode. An internal self-test is executed and all senders are checked for correct signals. If the ALPHAMFD discovers a fault, it displays an ERROR-code. A list of all possible ERROR-codes is listed in section 7.1.10 .

    Because it is very important to comprehend the different speed ranges at a single glance, self adhesive coloured marker rings in white, green, yellow and red are included with every ALPHAMFD. These rings can be mounted to the speed indicator corresponding to the speeds of the individual aircraft (Vno, Vne, Vso, Vs1, etc.) 4.1.3 Stall-Alarm...

    0.25 m/s. Values between +/- 10 m/s are displayed (or the equivalent in ft/min) The ALPHAMFD has two different ways of indication values on the round analogue scales. They can be chosen according to personal preferences in SET-Mode 17.

  • Page 18: Sector Display

    The flight time is measured as soon as the speed exceeds 50 km/h IAS. This moment is also registered as take-off time and can later be called up in the MEMO-Mode. The flight time is stopped as soon as the ALPHAMFD registers speeds of less than 50 km/h IAS.

    It is possible to set a factor "multiplied by 4, 2, or 1 or "divided by 6, 4, 3, 2". The generators of Rotax 582 and 503 engines give 6 pulses per revolution, so the ALPHAMFD must be set to "divided by 6" for use with these engines. ALPHA ALPHA...

    Additionally, the total running time of the engine of all flights (Engine Hour Meter) is displayed in SET-Mode 4. This value can not be changed and does not get lost when disconnecting the power of the ALPHAMFD. The value is shown in full hours. WARNING! Never disconnect the ALPHAMFD from its power supply before switching it off.

  • Page 21: Fuel Flow Meter

    The fuel flow sender transmits pulses to the ALPHA ALPHAMFD according to the actual fuel ALPHA ALPHA consumption. The ALPHA ALPHAMFD converts these pulses to the fuel flow and fuel state ALPHA ALPHA indication. WARNING! After filling up the aircraft, the actual contents of the tank must be input into the ALPHA ALPHAMFD (see section 5.3.8).

    WARNING: We recommend using the measuring method with only one fuel flow sender for engines with a fuel flow back system. The indicated values are not only more precise than when using two senders, you only have to buy and mount one sender. Recommended way of measuring: Measuring fuel flow with ONE Fuel Flow Sender for engines with fuel flow back system Motor...

    ALPHA has 4 Type K ports and 2 Pt100 ports. The ALPHA ALPHAMFD constantly monitors all senders for faults, e.g. cable breaks. If an ALPHA ALPHA error is found, the audio alarm is sounded through the Intercom and the respective display starts flashing.

  • Page 26: Display Of Temperatures

    5.8 Oil Pressure and Low Oil Pressure Warning The ALPHA ALPHAMFD can monitor oil pressure in two different ways, depending on the ALPHA ALPHA type of the oil pressure sender being used: You have to set the type of oil pressure sender in SET-Mode 29.

  • Page 27: Analogue Oil Pressure Sender

    The oil pressure is displayed with 3 digits and a resolution of 0.2 bar (or 2 PSI). The oil pressure unit can be set in SET-Mode 26, bar or PSI is possible. The ALPHA ALPHAMFD is designed to be used with the VDO Oil Pressure sender. It ALPHA ALPHA will not indicate correct values with other types of oil pressure senders.
