3. Important Directions

3.1. Care

Like every electronic instrument or camera, the VOLKSLOGGER also requires proper

treatment, to assure as long and as trouble-free a life span as possible. Therefore the following

directions should be strictly followed !

•Do not expose the instrument to direct sunlight for extended periods of time on the

ground (closed cockpit on a standing aircraft) but keep it covered (canopy cover,

paper, hat, etc.).

The temperatures, which black instruments in the cockpit of an aircraft on the ground

can reach (far above 80°C) will eventually damage the display and also the

electronic. This may lead to total failure or a shortening of the useful instrument

life.

•Do not store the instrument in high humidity (during the night/winter in the aircraft or

trailer) since the condensation caused by the cooling can penetrate into the

electronics and damage it.

•Do not clean the case and display with waterbut only with a lint-free rag (preferably

cotton) moistened (not dripping wet) with Denatured Alcohol or Ethanol. One has to

be careful not to let any liquid penetrate into the instrument or damage the label/seal

on the back.

•Do not use ACETONE or any other harsh solvents since these destroy the labels!

3.2. Safety Directions for Installation

Failure to follow the Safety Directions can cause damage to the instrument and surrounding area.

•No fuse

is built into the instrument. Therefore, an instrument fuse (500mA, slow-blow) has to

added during installation in the aircraft, before connection to the electrical system, to prevent

fires

or other damage caused by short circuits in cables or instrument.

The operation of the instrument with a fuse is part of the warranty qualification.

•There is no over-voltage protectionintegrated into the instrument. An exceeding of

the stated operating voltage leads to damage of the instrument.

•The instrument case is internally connected to electrical mass (negative ground).

Please ensure you take this into consideration during installation.

•Should the Volkslogger be rigidly connected(screwed) to parts of the canopy frame,

the cable should be lead through an easily separable intermediate connector. Ignoring

this statement can cause a failure of the canopy release in an emergency!

3.3. Installation

3.3.1. Mechanical Installation

Due to its small size the Volkslogger can conveniently be mounted on an existing

camera bracket. This allows access to all keys and easy reading of the display during

flight. For attachment, the underside of the instrument case contains three holes with

M5 thread (metric, 5mm) (Camera thread (1/4”-20) does not fit!!)

In case no camera bracket is available, the logger, due to its low mass, can also be

fastened with Velcro to the instrument console.

During installation, assure that the integral antenna has a clear view of the sky and is not

shielded by metal or carbon fiber parts.

In case the instrument should be installed in the baggage compartment, attention must

also be paid to the “clear view of the sky”. (Caution: Carbon fiber or metal parts shield

the GPS reception, plastic and wood are usually not critical).

To prevent accidental operation of the buttons by moving objects, the buttons can be

locked. (Menu: ACT.LCK). During the time the buttons are locked, the input code for

unlocking them is shown on the display.

The statements for mounting instruments and antenna are also valid for instruments with

external GPS-Antenna.

3.3.2. Electrical Installation

Power supply and communication with PC or flight computer are achieved

simultaneously over a 8-pin Western-Plug (RJ-45) on the left-hand side of the

instrument. Either the PC-readout cable or the aircraft installation cable is connected to

it.

Caution is advised during connecting the plug of the cable.

Functions of the wires on the Logger Connection Cable:

brown and brown-white: Positive wire of the power supply (+12V)

orange and orange-white: Negative wire of the power supply and the data line

blue: Data output (PC-Communication or NMEA)

green-white: Data input (PC-Communication)

We remind once more about the necessary fusing of the supply voltage!

The instrument should be connected to the aircraft power circuit by a qualified technician.

The functions of the wires have to be strictly observed. Non-compliance may seriously

damage the electronics of the VOLKSLOGGER.

The operating limits given in the technical data are stated in order to avoid damage to the

instrument. The instrument is internally protected against polarity reversal.

Nevertheless, the proper polarity should be observed during connection.

Note: Even though the instrument itself is protected against polarity reversal, a connected

flight computer can be damaged over the interface when the polarity is reversed in the

VOLKSLOGGER.

The VOLKSLOGGER has no internal buffer against momentary power interruptions. This

has the advantage that there is no part, which deteriorates and would have to be replaced

every 2-3 years by the manufacturer. Therefore, the power supply of the instrument has

to be protected against momentary drops below the minimum voltage. In particular

during switching of batteries such voltage drops can take place, which will lead to a

separated flight record during readout. This means that the recording of the flight

consists of several files, which is accepted reluctantly or not at all by the evaluator.

The circuit shown is meant as an example for a buffered and fused installation.

Alternately it is recommended to use a separate logger battery (Gel-Cell, 12V, 1.8 Ah),

to which no other power consuming devices are connected.

4. SHORT OPERATING INSTRUCTIONS

In the following text the operation of the instrument is described briefly. This chapter is

in no way meant to be a substitute for studying the complete manual but it essentially

describes the steps necessary to record a free flight, without input of the flight declaration

and without the use of the navigational support by the VOLKSLOGGER.

•Connect the VOLKSLOGGER to the power supply cable and mount the instrument in

the aircraft (the VOLKSLOGGER does not have an On/Off – switch. Operation is

started by the connection to the power circuit).

•After connection to the power supply, the display of the VOLKSLOGGER shows a

countdown timer. During this time a connection to a PC can be made for the purpose

of data transfer. If no PC is connected, the instrument switches to normal operation

mode after 9 seconds.

•Wait until the VOLKSLOGGER goes through the information displays. It will show

the instrument serial number, the hardware version, the firmware version and the

condition of the electronic seal.

•After the information pages, the VOLKSLOGGER immediately commences

recording. For correct GPS-reception it is necessary to wait for the contact with

valid satellite signals. The number of received satellites is shown in the lower left of

the display. Only after 4 (preferably 6) satellites are received, a correct positional

fix is possible. Additionally, the status of the reception is shown. See chapter 5.3.3.

Navigation.

•When the memory is full, the VOLKSLOGGER stops recording. Therefore, sufficient

memory space has to be available for a complete record of the flight. You either

have to erase the memory before the beginning of the flight (ACT.MEMCLR) or the

recording interval has to be increased (CFG1.LOG.INTV) until the available

recording time appears to be sufficient for the flight.

If the available residual recording capacity is less than 8 hours, a (visual and

acoustical) warning is unless it has been deactivated (Menu CFIG1.SND.WRN)

The available capacity of the memory (Flt-MEM) can be examined in Menu

INF.MEM. The remaining recording time is depending upon the number and size of

the recordings of old flights still in memory as well as the selected recording

interval.

•After landing, transfer of the recorded flight from the logger is by means of a PC

(under supervision of an official observer if necessary) for storage it on a floppy

disk or other suitable recording device.

5. Operating Instructions

Introduction

The VOLKSLOGGER does not have an ON/OFF switch. The operation starts by

connecting the power cable.

The complete operation of the logger is accomplished through the use of three keys on

the right-hand side of the instrument face, next to the LCD-Display. These keys are

numbered in sequence from top to bottom, Key (1), Key (2) and Key (3). Lettering on

the instrument face was omitted because with the many different functions of the keys

that would be confusing.

Figure 2: Front View VOLKSLOGGER

The keys have different functions depending on the display and the operating mode of

the VOLKSLOGGER. For instance, in the menu-mode Key (1) has the function of an

<escape>-key (exiting the menu-level to the next higher level). Key (2) has the

<Next>-function. You can select the displayed menu-items with it. Besides this, in

modes where you can change a value, Key (2) can be considered a (-) Key. Key (3) has

the property of an <Enter>-Key. With it you can go to the selected menus. In the

modes where a value can be changed, Key (3) has the function of a (+) Key.

Every key has an auto-repeat-function, which means that if it is held depressed for a

certain time (≥½ second), it acts as if it is pressed repeatedly in rapid succession.

The operation of such a complex instrument as the VOLKSLOGGER with only three

keys may appear difficult and cumbersome at first glance. However, it complies with

the by now accepted philosophy of minimizing the number of operating elements in an

instrument (for instance, modern laser printers can be operated with only one key).

After only a short period of familiarization and with a little practice, the user will find it

easy to operate and program the instrument by means of the keys.

Further details about the operation and the functions of the keys in the particular

situations are explained in the respective chapters (in particular chapter 5.7. Basics of

Data Input)

5.1. Switching On

After connecting to the power supply the VOLKSLOGGER asks the user for a

connection to a PC with the readout program running (Display: “waiting for PC”).

Unless within 9 seconds a data connection with a PC is established or one of the keys is

actuated, the instrument starts displaying a sequence of introduction screens (PC

connection may also be established through the menu ACT.PC):

1. Introduction Screen

Security Seal

is OK. Condition of the Electronic Seal:

Security-seal is OK

The undamaged condition of the seal is confirmed. The instrument has not been opened

since it was sealed by the manufacturer.

Or:

Security Seal

is not OK!!! Condition of the Electronic Seal:

Seal is broken

The system has determined that an unauthorized attempt at opening the instrument case

has been made. It therefore has to be assumed that a manipulation on the hardware has

taken place. The instrument functions remain intact but it is no longer possible to supply

flight data with the required check-sum. All flight data supplied by this instrument will

be recognized by the validation program as invalid and will be rejected by the FAI or

National Authorities.
