Source text - English Control system connections form the "nerve tract" of an industrial plant. Their smooth operation requires a high degree of plant reliability and availability. The interfaces in automation technology react very sensitively to surge voltages. It is therefore necessary to have surge arresters with combined protective circuits, which can unify the coordination of lightning protection zones as needed. The lightning protection zone concept is thus maintained. The protection module is selected to match the signal level, measuring principle, installation location and the operational electric strength. The grounding concept specified for the application is considered here. This is the only way controllers and measuring sensors can be protected effectively against the hazards of surge voltage coupling along the conductor path or via the ground potential.
Translation - Russian Связи систем управления образуют «нервную систему» производственного предприятия. Для их бесперебойного функционирование требуется высокая степень надежности и готовности к работе предприятия. Интерфейсы в технологиях автоматики очень сильно влияют на скачки напряжения. Именно поэтому необходимы разрядники для защиты от перенапряжений с смешанными цепями защиты, которые могут унифицировать согласование зон молниезащиты так, как это необходимо. Таким образом, вводится понятие зоны молниезащиты. Блок защиты подбирается таким образом, чтобы соответствовали друг другу уровень сигнала, метод измерения, размещение установки и рабочая электрическая прочность диэлектрика. В данной статье, рассматривается понятие заземления, соответствующего техническим условия на применение. Это единственный способ для эффективной защиты контроллеров и измерительных датчиков от рисков скачков напряжения, которые образуют связи по пути тока или через нулевой потенциал.

Source text - English 1 Scope and field of application
1.1 This standard describes the examination of special steels for non-metallic inclusions of sulfidic and oxidic nature. Both macroscopic and microscopic methods are used for this purpose. Microscopic examination can be carried out using a metallurgical microscope and auto¬matic devices. It has not been possible to standardize instrumentation for automatic evaluation of micrographs because development of such instruments is not yet complete. This standard specifies a method to be applied for microscopic examination using a metallurgical microscope and a set of standard diagrams arranged in a systematic sequence, which enables the micrograph to be described on the basis of the type and size of inclusion (length and width or diameter) and the frequency (standard diagram plate 1). An index proportional to the content of inclusions from a specified limit size upwards can be calculated separately for the oxide and sulfide components or as a total value. There is also provision for determining maximum sizes.
Translation - Russian 1 Предмет исследования и область применения
1.1 Данный стандарт описывает анализ высококачественных сталей на наличие неметаллических включений сульфидного или оксидного происхождения. С этой цель применяются как макроскопические, так и микроскопические методы. Микроскопический анализ может выполняться с помощью металлографического микроскопа и автоматических приборов. До настоящего времени не представляется возможным стандартизировать измерительные приборы для автоматической оценки микрографических снимков, так как разработка таких приборов еще не завершена. Данный стандарт оговаривает технические условия для методики, которая должна применяться в микроскопическом анализе с помощью металлографического микроскопа и набора стандартных графиков, расположенных в систематизированных последовательностях, что дает возможность обработать микрографический снимок на основании типа и размеров включений (длина, ширина или диаметр), а также частоты (стандартный плоский график 1). Индекс, пропорциональный содержанию включений, начиная с оговоренных размеров и выше, может быть рассчитан отдельно для оксидных и сульфидных составляющих, или как общая величина. Также обеспечивается определение максимальных размеров включений.

CHAPTER 6
MAINTENANCE, FAULT LOCATION AND REPAIR
6.1 MAINTENANCE
6.1.1 Introduction to Maintenance Activities
Maintenance of a system can be defined as preventive and corrective maintenance (corrective maintenance
may also be defined as ’Repair’ activity in case of a fault). Within this chapter two basic types
of preventive maintenance are described, namely periodic maintenance and normal maintenance.
It is essential to ensure that the radiated signals remain within the fixed tolerances at all times after
the navigation system has been handed over for service to air traffic. With this aim in mind, ICAO (see
document ICAO DOC 8071, Vol. I, chapter 4 for ILS) recommends verifying the most important signal
parameters of the ground station within the framework of periodic maintenance to maintain the operational
integrity and serviceability. In addition, flight testing is required to confirm the correctness of
the setting of essential signal−in−space parameters to determine the operational safety and acceptability
of the ILS installation.
NOTE: Change of parameters is allowed only by maintenance people with specific access level
(i.e. > level 2) to the PC user program (ADRACS or MCS). Changes to the established
monitor alarm limits should only be done during flight check procedure.
In the Navaids ILS 420, all the main parameters are maintained at the preset values throughout the
entire life of the system by means of a digital controlled transmitter, so that drift as a result of ageing
should not normally occur. In addition, the radiated signals are checked by two high−precision microprocessor
controlled monitors. These prevent faulty signals from being emitted by either switching
over to the standby transmitter or shutting down the system completely. Since, moreover, no parts
which are subject to mechanical wear and tear are used, the periodic maintenance intervals can be
made longer than usual and the number of measurements restricted to a minimum. In addition to the
periodic maintenance work, there are a few activities of normal maintenance which should be performed
as and when necessary.
NOTE: The responsible authorities (e.g. ATC/Controls) must be informed before commencing
any maintenance work in accordance with national regulations!
6.1.2 Work on Equipment sensitive to electrostatic Charge
A grounding strip with a large cross−sectional area is connected between the shelter grounding terminal,
the equipment racks and the worktable to act as the system ground and to eliminate electrostatic
charges. It is firmly connected to the table and a grounding bus on the working surface. This
system ground should not be connected to either the mains protective ground conductor or to housings
and grounds of external consumers, i.e. consumers not associated with the worktable, except
at the potential equalization bus for the overall installation. The protective ground wire offered with
mains cable or plug connections is not suitable for potential equalization of equipment on a worktable.
Depending on local circumstances, it can carry quite high RF interference voltages.
Mains−supplied equipment, power supplies and test equipment should be connected via two−wire
cables and two−pin plugs. For measures to be taken with respect to components sensitive to electrostatic
charging (MOS, Low Power Schottky) please refer to the customer service documentation
of the manufacturer. If an employee is required to handle subassemblies for transport purposes, he
should place both hands flat on a grounded surface beforehand (e.g. on the ground bus of the work
table). The module can be picked up by its insulator immediately following this potential equalization.
It is safer to avoid touching the terminals. Only remove short−circuit links where absolutely necessary.
Place printed circuit boards only on tables with a conductive, grounded working surface. Leave
individual subassemblies in the antistatic plastic bags for as long as possible.

6.2 PERIODIC MAINTENANCE
We recommend for a CAT. III installation to perform the maintenance activities listed in the table below
weekly, quarterly, half−yearly or yearly (more details are given in ICAO DOC 8071, Vol. I, 4th Ed.). For
other categories (CAT. II or I) the scope of activities should be defined accordingly. The half−yearly
checks (items 13 to 15) are performed mandatory. Besides the recommended activities, the responsible
authorities may define individual procedures depending on local guide lines and requirements.
The following measuring instruments are recommended for maintenance on site:
− Desktop PC or Laptop with PC User Program (ADRACS or MCS) used for maintenance on site
− ILS test set for field measurement (e.g. PIR)
− Multimeter, frequency counter, frequency generator, spectrum analyzer (e.g. HP8561E, 30 Hz to
6.5 GHz), cables, adapters
− If non maintenance free batteries are used:
Battery maintenance equipment (acidimeter, acid syringe, areometer, thermometer, funnel). Refer
to the instructions of the manufacturer.

6.2.2 Check of Transmitter Parameters and Monitoring
There are various methods to validate periodically the transmitter and monitor functions depending
on the procedures laid down by the national customer procedures. For example course alignment
may be checked by center line runs with a test vehicle weekly, but in case a farfield monitor is available
and by integrity and stability history, the maintenance intervals may be increased. The check of monitor
parameter alarms is proposed to be done with a change of corresponding transmitter parameter
(power level, DDM, SDM etc). In addition, there are some special checks to be performed which are
described separately. Item 4 is only performed with LLZ systems. The previous check ’Polarization’
is still performed only with the flight check during first alignment. For item 17, it is recommended to
use a spectrum analyzer connected to a 50 dB directional coupler which is inserted in the feeding
cable at the output on top of the cabinet.
NOTE: The procedures to change transmitter parameters and check of monitoring alarms can
be performed locally via a connected Laptop/PC or remotely via the RMMC system.
6.2.2.1 Shut Down Timing Test (STT)
The purpose of the Shutdown Timing Test is to measure the time it takes to accomplish a complete
shutdown when the radiating signal source(s) is (are) invalid. The STT measures the time to complete
shutdown both on dual−equipment (DE) systems and on single equipment (SE) systems. The test
is performed with the PC User Program:
a) Use menu ’Commands’ − ’More commands’ − ’Transmitters’ − ’TX Miscellaneous’. Select ’Initiate
transfer/shutdown test’ to activate the STT. The result is shown in the window MON1(2) ’Transfer
Timing Data’: the item ’Test Procedure Result’ must show ’OK’.
6.2.2.2 Check of Carrier Frequency
Validate set station frequency with a frequency counter or similar. The measurement is performed at
the affected TX in Stdby mode (this RF path includes a 35 dB attenuator):
a) Switch off both TX1 and TX2. Remove RF cable from J25 (Stby CRS CSB) at PIN−Diode Transfer
Switch, rear side of cabinet. Connect Frequency Counter to J25 (stby CSB out).
b) Switch on both TX1 and TX2. Open dialog ’Transmitter1−Waveform Data#1’ and ’Transmitter2−
Waveform Data#1’. Note down value of ’CRS CSB SDM’ of standby transmitter. Set it to 0 %. Validate
indication of station frequency. After measurement, reset ’CRS CSB SDM’ of standby transmitter
to noted value. Change transmitter, repeat step b).
c) Finally switch off both TX and connect as normal again. Switch on both TX.
6.2.3 Performing Check of Shutdown Circuits and Control Logics
Transmitter shutdown occurs with the activation of either the modulation shutdown (Shutdown B,
modulation signal at LGA off), or the synthesizer shutdown (Shutdown A, synthesizer carrier generation
off). To ensure that no latent failure exists in the shutdown paths (LGA or SYN) that would prevent
its capability, it is to verify that a transmitter shutdown occurs solely due to this path. To perform the
test, refer to section 6.2.8. Follow the procedure described in the ECU test data sheet.
6.2.3.1 Check of ECU Interlock Shutdown Control
NOTE: Perform this test only if the ECU Interlock function is really used.
Preparation: The runway to which the station under test belongs, must be the inactive one. The correspondent
station status must be ’OFF’. Verify that the DIP−switch SW4(SW1)/2 at the ECU subassembly
is set to ’open’: Interlock enabled.
Test action Expected result
At the LCP of the station , perform a ’TX on’ command. The transmitter is turned on, but station remains not radiating
because the ECU keeps both shut down paths ’OFF’ (SYN and
MOD shutdown).
Station status changes from ’OFF’ to ’Runway OFF’.
After test has passed, return to normal operation

6.2.4.1 Performing advanced Check of MIT Function (ECU 120571−0003 only)
With the ECU 120571−0003 an advanced check of the MIT−Function is introduced. This check must
not be performed with the ECU −0001 and −0002. The MIT check in section 6.2.4 can be performed
for both the ECU −0001/−0002 and the ECU −0003.

Verify all reading return to normal conditions.
Perform ’Reset ECU’ to restart the system. Both TX on. Verify all reading return to normal conditions.
Equipment is serviceable. End MIT check.
6.2.5 Check of Battery Function
This check shall ensure that the battery is able to supply the installation in case of a mains interrupt.
To check the battery function perform the following procedure:
a) Both TX are on. Switch off mains supply, e.g. switch off the ACC modules. The equipment should
be supplied by the battery and runs without interruption. The LCD screen should indicate a maintenance
alert with ’AC1 Failure’ and ’AC2 Failure’.
b) After a few minutes (e.g. about 5 min) switch on ACC modules again. The equipment should be
supplied by the mains again and runs without interruption.

6.2.6 Documentation of System Data
The data recorded during the flight test is the only data which is binding for operation of a navigation
installation. It is advisable to check this data in accordance with the chart for periodic maintenance.
A documentation is performed by the printer of the connected PC or in a file for the transmitter data
and monitor data on the PC (.lda files).
The first data so−obtained of the basic adjustments of the alignment procedure at commissioning
and flight check should be recorded and stored in a reference file or on a floppy disk. One hardcopy
of the data should be completed with date and signature. The same procedure should be followed
when performing further checks, when the data recorded can be compared with the original flight
check data.
6.2.7 Cleaning
CAUTION
Cleaning aids, such as brushes and dusters, must be made of antistatic material. See also
the instructions in Section 6.1.2.
− Shelter
Brushes, dusters and a vacuum cleaner should be used to clean the transmitter rack and the rack
for the battery−charged power supply. The transmitter room should not be cleaned with a broom,
but rather using a vacuum cleaner.
The floor should be washed regularly every 6 months. The detergent should be added in small
quantities only to the water; no aggressive cleaning agents should be used. Floor cleaning agents
should be avoided, since these have the same effect as a dielectric and encourage the build−up
of static charges. If the floor covering is made of a conductive material, then similarly only those
cleaning agents expressly recommended by the manufacturer of the floor covering should be
used.
The air filters of the fans, ventilation openings or air conditioners in the shelter should be checked
from time to time in accordance with the volume of dirt which accumulates at the particular location.
The filters should be replaced by new ones before they become clogged. If no new filters are available,
the dirt may − as an exceptional measure − be banged out of the old filter to permit the filter
to be re−used. Damaged filters on the other hand, should not be re−used. If an air conditioner
should become iced−up, switch it off and let it defrost. Observe the manufacturers maintenance
recommendations. The separate battery compartment should be dusted out once a year. Avoid
transferring dirt from the battery compartment into the transmitter room.
− Transmitter rack
Only two types of alcohol, namely Ethyl alcohol or Glycol,or clean water should be used to remove
layers of dirt on the LCP panel. Cleaning procedure: Moisten a cloth a little with one of the liquids
mentioned above and remove dirt.
Dusting of the subassemblies should only take place in conjunction with removal of a subassembly
when this becomes necessary in any case for some other purpose. Even then, subassemblies
should only be dusted if dust can be detected by means of a visual check. They should always
be dusted using a soft brush, and if possible with the aid of a vacuum cleaner. During such operations
it is essential to observe all precautionary measures described in Section 6.1.2 for voltage−
sensitive semiconductors.
− Antenna
Inspect complete antenna, monitor dipole and the equipment installation for any damage caused
by corrosion, rodents, termites, or others. Air traffic control should be informed before the antenna
will be inspected. Normally the antenna is not radiating while inspection.

6.2.8 Performing Check of Shutdown Paths
NOTE: This procedure will take the station out of service.
The shutdown paths are checked for both Shutdown A path (carrier off) and Shutdown B path (modulation
off) for the TX1 and TX2 each. Use Oscilloscope with probes for signal check at ECU (voltage)
and MODPA TP1 (CSB) and TP2 (SBO). If any test fails the ECU, SYN or LGA card should be replaced
before the system is put back into service. The procedure should be accomplished without removing
the ECU card from the equipment cabinet. The jumper should be repositioned without removing
power from the ECU card. When a jumper is in any of the ’park’ positions, the ECU will not have a
test fault. The park positions are used only to hold jumpers. To perform this check, use proposed form
and maintain it in station records. Fig. 6−2 shows the jumper and testpoints. With ECU board
120571−0003, regard the different jumper label noted. Proceed as follows:
− Set key lock switch at LCP to ’Maintenance’. After the test, set key lock switch to previous position.
− Log on to system in level 4. With transmitters on, verify that there are no alarms, alerts or ECU faults
other than the maintenance switch notice indicated on the LCP screen. If there are, troubleshoot
and correct before continuing.
The form comprises following checks:
− Functional test modulation shutdown path TX1 (Shutdown 1B, Shutdown 1A disabled)
− Functional test modulation shutdown path TX2 (Shutdown 2B, Shutdown 2A disabled)
− Functional test Synthesizer carrier shutdown path TX1 (Shutdown 1A, Shutdown 1B disabled)
− Functional test Synthesizer carrier shutdown path TX2 (Shutdown 2A, Shutdown 2B disabled)
− Functional test of Control Logic 1 and 2 and 3rd Shutdown Path (incl. clock detector)
Up to 8 jumpers should be available to perform the test settings.

6.3 NORMAL MAINTENANCE
6.3.1 Replacing the Lithium Battery (LCP)
To back up the real time clock in case of a voltage drop, the subassembly LCP contains a Lithium
battery (LS 14250, 3.6V/0.95Ah, make SAFT; Thales Ref. Nr. 97991 28479). Lithium batteries have an
extended life time. Also not in use, it ages as a result of self−discharging. Therefore it is recommended
to install a replacement battery after about five years operation, or its voltage drops below
3.0 V. The battery back up function is enabled via jumper, set during first setup or before replacing
the respective pc board. Always observe the label on the battery. The Lithium battery has to be replaced
by the same battery type. Other types of lithium batteries are not approved by Thales.
WARNING
Do not recharge, disassemble, heat above 100 °C or incinerate the lithium cell. Do not
short circuit, or solder directly on the cell. Disregard of the norms regarding the use of
lithium batteries may cause risk of fire, explosion or leaking out of toxid liquid and gas.
Run−down batteries are objects that can pollute the environment and must be disposed
of with proper precautions. Regard national regulations.
The backup battery can be replaced without switching off the power. The battery is disconnected with
jumper X36 on the LCP. To unsolder the battery a soldering iron with a grounded soldering tip should
be used. A battery short−circuit via the soldering iron for the duration of soldering is unlikely to harm
the relatively high−impedance battery, but should however be avoided wherever possible.
Replace the Lithium battery as follows:
− Open the cabinet front door. Remove jumper X36 on the LCP.
− Unsolder the minus and plus pole of the old battery from the soldering terminals on the LCP board.
− Remove the old battery
− Re−tin the soldering terminals of the new battery in order to ensure a good soldered connection.
− Insert the new battery, and solder the minus and plus pole of the battery to the soldering terminals.
− Set jumper X36 on the LCP. Close the cabinet front door.
6.3.2 Check of Emergency Battery Voltage
The overall battery voltage is monitored by the transmitter assembly LCP. However it is recommended
to measure the battery voltage to check the performance of the battery. The voltage measured is that
between the BAT1 or BAT2 terminals against GND (BAT0), see 2−13, 2−14. The half voltage value
should be exactly half the full value. Should unbalance occur, a fault is indicated. The deviation in the
ratio of 2:1 for the half voltage measurement increases the further the aging process of a cell is advanced.
If the deviation from the ratio of 2:1 is minimal, the battery can be maintained in service, but
should be kept under observation.
If the deviation is greater (from as little as a few tenths of one volt), each cell must be measured under
load in order to determine the weak cell. This should be replaced by a new cell as soon as possible.
The battery half to be examined may be determined as follows.
Voltage ratio: locate faulty cell:
> 2:1 (e.g. 47: 23 V = 2.043:1) between center and minus
< 2:1 (e.g. 47: 24 V = 1.958:1) between center and plus
CAUTION
Before replacing the battery or individual cells, always check:
− Is the battery−charged power supply switched on ?
− Switch off fuse switch F20 (50 A) in battery fuse box, if the BCPS is on.

6.3.3 Matching the charging Voltage of BCPS Modules
6.3.3.1 Reasons for Voltage matching
The BCPS has a fixed voltage of 54 V±3 % for parallel operation with lead batteries. It is not possible
to vary the output voltage for operation with other types of battery, e.g. nickel cadmium batteries. An
adjustment of ±1 V is however possible on the front panel of the slide in units. This is intended for
optimization of the trickle charge. The most important parameter for operation of lead batteries at the
BCPS is the trickle charge voltage. This voltage is 2.23 V/cell ±1% in accordance with VDE (registered
society of German electrical engineers).
In the interests of optimizing the charge Thales have utilized the upper tolerance limits and fixed the
trickle charge voltage at 2.25 V/cell. This results in a trickle charge voltage of 54 V for a battery with
a rated voltage of 48 V. Strictly speaking however this fixed trickle charge value of 54 V is only valid
at a temperature of 20 °C in the battery compartment. If the temperature rises above 20 °C, it is necessary
to reduce the voltage in order to maintain a sufficient difference with respect to the gassing voltage
of 2.4 V/cell. If the temperature falls below 20 °C, it is necessary to increase the charging voltage
in order to ensure optimum charging. The relationship between the temperature and the charging
voltage is shown in the table below. It is valid for the types of battery proposed or provided by Thales.
Please consult the manufacturer if using other types.
BATTERY TEMPERATURE IN °C TRICKLE CHARGE VOLTAGE IN V
10 55.08
15 54.54
20 54.0
25 53.46
30 52.92
The internal temperature in the battery compartment is subject to fluctuations dependent on the time
of day and time of year. The considerable mass of the batteries and the associated high thermal inertia
mean that temperature fluctuations dependent on the time of day are insignificant and can be ignored.
It is necessary on the other hand to determine the average temperature in the battery compartment
during the hot and cold seasons or to estimate it on the basis of experience. The optimum charging
voltage can be read off from the table when the average temperature has been calculated.
It is not necessary in moderate climatic zones to take seasonal fluctuations into account. If the batteries
are accommodated inside a shelter or a building, the fluctuations between summer and winter are
not very great, and the mean temperature will not deviate substantially from 20 °C.
In such cases it is not necessary to optimize the trickle charge voltage as described here. This only
becomes necessary if the batteries are installed outside the shelter or in hot or cold zones without
an air−conditioned battery compartment. If the mean annual temperature is known during the installation
phase, adjustments can be carried out by the Thales installation team. Otherwise they should
be carried out by the customer’s own maintenance personnel as follows.
6.3.3.2 Matching the Voltage
NOTE: This procedure is performed once during installation or if other battery types are used.
The battery must be connected. Switch off the transmitters. Using the switches on the front panel
switch off the ACC units except the outer left one, which has to be adjusted first. Beginning with left
ACC unit adjust the ACC units as follows:
− Connect a digital voltmeter to the test jacks on the front panel of the switched on ACC unit.
LLZ 421
Operation and Maintenance Maintenance
ILS 420
Ed. 01.10 SOAC 6−13
− Set the desired voltage carefully at the potentiometer on the front panel with the aid of a calibration
screwdriver. It should be possible to obtain the value specified in the table in 6.3.3.1 to within a
tolerance of ±0.2 V.
− Switch off the adjusted ACC unit.
− Switch on the next ACC unit and adjust it in the same way.
− Adjust all installed ACC units in the same way.
When all units have been set in this way measurements should be performed as follows:
− Disconnect the battery.
− Perform measurement between BAT and −BAT on the BCPS terminal plate using a digital voltmeter:
First measurement : Transmitter off, BCPS without load
Second measurement : Transmitter on, BCPS with load
The values should not deviate from the set value by more than ±1 %. If the deviation is greater, the
relevant module can be determined by deactivating the power units individually and observing the
voltage change. The voltage of this unit must then be corrected upwards or downwards. The BCPS
is then ready for service.

6.4 STARTUP, CARE AND MAINTENANCE OF THE LEAD BATTERY
6.4.1 Startup Specifications for the Lead Battery in Navigation Installations
6.4.1.1 General
For countries in Europe, the sets of lead batteries in the navigation installations are normally supplied
already filled and charged by the manufacturer. On site the batteries then merely need to be installed
and connected to the power supply unit of the navigation installation.
NOTE: Maintenance free batteries need no further maintenance activities.
Batteries supplied in a non−filled state to their point of installation must be set up, filled and charged
there in accordance with the manufacturers handling specifications. The batteries can be supplied
non−filled in either a dry precharged state, or a non pre−charged state (see 6.4.1.3.2 and 6.4.1.3.3 ).
The battery may not be removed from its transport packing until immediately prior to startup.
CAUTION
Maintenance−free batteries have to be set into operation within half a year after delivery
to prevent drawback in the battery lifetime.
The startup procedure comprises the following stages:
a) Installation on site, interconnection of the cells with the cell connectors and connection to the
electrical installation;
b) Filling with accumulator acid;
c) Immediate subsequent charging or activation of the plates (see 6.4.1.3)
d) Immediate subsequent activation in standby parallel mode.
These instructions do not cover the installation work, but instead deal merely with filling and activation
using tools which, even in remote areas, are either available or easily obtainable. They moreover apply
only to batteries for which a rated acid density of 1.24 kg/l is specified by the manufacturer, e.g.
Gro E, iron−clad and block batteries, and not to starter batteries or batteries with a fixed electrolyte.
The aids required are as follows:
− Accumulator acid
The acid must have a particular density. If this value is incorrect, the mixture should be made up
of high−density sulphuric acid and specially purified water (see 6.4.1.2.2 ).
− 1 Acid syringe with areometer

By pressing the [Enter] or the [U]/[ ] key, the data is displayed in an ascending order. By pressing the [P]/[-] key, data is displayed in a descending order. Pressing the [Q] key at any time will exit the Diagnostics menu. The ST98 functional data in RAM is saved in the USER area of the Non-Volatile Memory (NVM). The user has the option to save user data to the USER Save area of NVM at any time. At completion of the FCI calibration, the data was saved to the FACTORY area of NVM. Each of these data areas may be viewed by the user (Refer to Menu item ‘S’ for more detail on saving and restoring the NVM data areas).
Example:
At BOOTUP or RESET, the following is displayed: “Initialization!”, with “FCI ST98” flashing, followed by “Heat On!”.
Pressing D [Enter] will display “USER Displayed” followed by “Change it ?

Dauphin AS365 Helicopter
Landing gear system
The helicopter is equipped with a retractable tricycle landing gear which includes two main landing gear units located aft of the aircraft center of gravity and a nose landing gear unit attached to the airframe structure.
The brake system is hydraulically controlled from the cockpit via transmitters slaved to the tail rotor control pedals, and by a braking relay powered by the hydraulic pressure from the utility system.
Shock strut tube
It is made from steel. It supports the wheel spindle on which is machined the lower attachment fitting of the torque links and the brake unit attachment flange. A bushing is screwed to the top part, which actuates a microswitch control button when the shock strut is fully extended.
Torque links
They consist of two identical light alloy links which are held together by a pin fitted with a ball-joint and an adjusting shim. The torque links are coupled to the strut housing and the shock strut tube by means of two bolts and nuts locked with cotter pins.
Low pressure chamber
It is situated between the strut housing and the cylinder. The hydraulic fluid is stored under the separator piston head.
