EDITORIALEverything is customized!

When putting together this latest version of our transportation customer magazineON TRACK! I was amazed to see how the trend of individualisation has become neccesary in so many different areas.

Whether it is ambient sounds in the train toilet that mirror the surroundings, Piezobuzzers installed in rail vehicles across the world that have customised programmedwarning tones or individually configured time relays for a clear view onboard the newRhine-Ruhr-Express. Thanks to intelligent equipment, we are now able to accommodatea wide range of demands without compromising on safety, efficiency or scalability in therail mobility area.

Speaking of mobility - LÜTZE TRANSPORTATION has got a lot of things moving! After moving into our own site, we want to lay the foundations for the continuous andsustainable growth of our rail division.

I hope you enjoy reading about it!

With kind regards,Ihr Udo Lütze

Having to go to the toilet on a train - thereare more pleasant activities. But in the CAT,everything is different. Just imagine - youopen the door of the WC and find yourselfin the Viennese Prater park with the bigwheel in front of you! Or in front of theHundertwasser house, the State OperaHouse, the Vienna Secession, the Town Hallor the Stift Klosterneuburg (monastery).

Rooms transformed; passengers enchantedThe operator of the CAT commissioned thepopular sightseeing locations to be "moved"on board into the six train WCs. The re-spective panoramic photos run from theside walls via the shelving, right down tothe toilet seat, covering the entire room.

With the additional acoustic backgroundmusic, passengers are per-fectly preparedfor their visit to Vienna.

Sounds to match the tourist attractionsMusic and suitable background noises thatmatch the respective motif enliven eachscenario. For example, in the WC contai-ning the Vienna Opera House, we can hearthe audience whispering; instruments aretuned and then Mozart's "Le Nozze die Fi-garo" begins. To complement the panoramaof the Prater park, we hear the theme musicfrom the film "Der dritte Mann" (The ThirdMan) with the un-mistakable zither soundby Anton Karas. Those visiting the toiletdecorated with Vienna's Town Hall will

hear market noise and the Johann Straussclassic "Wiener Blut" (Viennese Blood). Aspecial fragrance is also added to the visualand acoustic accents for further sensory en-joyment.

As of 2018 the Rhein-Ruhr-Express(RRX) will be crossing one of the lar-gest built-up areas in Europe. This willoffer easier mobility to almost ten mil-lion people living in the region. Onboard each RRX train from SIEMENSare three time relays from Lütze Trans-

portation GmbH to control the wind-screen wipers on board. To ensure thatthe train drivers always have a clear vi-sion when moving through the urbanland-scape at speeds of up to 160 kilo-metres an hour.

We initially received an enquiry from theFBO Group, one of the largest suppliers inthe rail industry. This French company alsoproduces windscreen wipers for both high-speed and super high-speed trains. Initiallya small control unit was planned to controlthe wipers in the electrical trains of the

type Desiro HC. However, this would havebeen problematic for the customer: a failurewould have brought the entire windscreenwiper system to a standstill. Also, the se-lected product was not suitable for use inrail vehicles because it did not comply with

the latest fire protection re-quirements forrail vehicles. The small control unit wasalso more expensive than the other feasiblesolutions.

Therefore, FBO decided to use ZR time re-lays with mechanical contacts, supplied by

LÜTZE TRANSPORTATION. There were,however, still two unanswered questions:would a time relay in this application sa-tisfy the specified precision of the timefunc-tion? Also: Can higher availabilityspecifications be reached? The final concept

e relay 60… heavy rain… great vision…al-lowed the wiper motor to be activatedthrough pneumatic electrical valves - i.e. in-ductive loads that need to be switched.

Controlling three wiper speeds

Idea number one: instead of one single con-

trol unit, it is better to have three ZR mul-tifunctional time relays DC 110 V. Eachrelay is configured with its own timefunction. The three relay outputs are eachconnected to an electrical valve to control,one of the three wiper speeds. The three

wiper speeds are achieved via a time delayprogrammed separately for each relay. Thissolution also rules out the possibility of aCommon Mode Failure because if a relayfails, the two other wiper cycles still func-tion. In the original system with a smallcontrol unit, a fault would bring the entire

windscreen wiper system to a halt and thetrain driver's vision would be impaired.

Inductive loads? No problem!

This is an electro-pneumatic valve that con-

trols the windscreen wiper via an inductiveload. If relays with mechanical contacts areused, a reduced service life must be expecteddue to a high level of wear on the contacts.Therefore, Lütze Transportation GmbH cameup with a second idea, ZR relays with semi-conductor outputs. These switch without

any wear, which is why the expected numberof operating cycles is much higher.Reliability is an important factor for thecustomer FBO, they want to ensure thattheir products operate for a long time. Evenif the train driver has never heard of MTBF

collaborative tests carried out by the engi-neers at FBO and LÜTZE TRANSPORTA-TION have confirmed that semiconductor

outputs satisfy the specified function andreliability. A high level of availability is hu-gely important for this function and out-weighs the cost benefits of mechanicalcontacts.

More benefits: Programming and diagnosis

The ZR time relay can be configured onany standard PC using the free software'LÜTZE Time Relay Configurator'. Thetime, operating and diagnosis functions

can be recon-figured easily when the relayis commissioned or after changes. Uponthe customer's request, Lütze Transporta-tion GmbH can also supply the time relaywith specific criteria.

There was another feature of the ZR relaythat FBO did not need, the configurable

digi-tal diagnosis output with an opticaldisplay. This may be a very helpfulfuction in certain cases.

Project of the century in the Rhine-Ruhr region

The solution for the windscreen wipers ofthe SIEMENS RRX trains was developedin successful cooperation with the FBOdevelopment department. The companynot only produces windscreen wipers andwashers, but also various valve types and

fittings for all reputed rail vehicle manu-facturers. At of the end of 2018, the RRXrail traffic concept plans to ensure that thefirst of 82 trains will be moving quicklyand comfortably on the tracks, in 15 mi-nute cycles at peak times.

The targeted expansion of the rail network

could help to shift 31,000 travellers fromthe road onto the rails every working day.

LÜTZE is thrilled to play a role in this en-vironmentally-friendly project for theRhine and Ruhr region. In line with theLÜTZE sustainability initiative SkyBLUE.

LÜTZE TRANSPORTATION presentsfour new relay components with positi-vely driven contacts that stand outthanks to their very narrow dimensionsof just 17.5 mm and up to four swit-ching contacts.

The new LÜTZE relays complete the Mi-crocompact series and are available for allrail-based on-board power supplies 24, 36,72 and 110 volt DC. Typical applications in-clude safety-relevant applications for swit-ching small to medium loads: e.g. for door

control systems, monitoring vehicle coup-lings, the brake system, the passengeremergency brake, traction release, SIFA(safety deadman circuit), PZB (intermittentautomatic train control) or the radio re-mote control.

The relays satisfy the standards EN 50155,EN 50121, EN 50124, EN 61373 and thefire prevention standard EN 45545-2. De-pending on the application, the relays areavailable with either 3 (2NO/1NC) or, onrequest, with 4 contacts (3NO/1NC bzw.

2NO/2NC). All contacts are positivelydriven according to EN 50205 applicationtype A.

Due to their small dimensions, the LÜTZErelay modules can also be used as space-saving substitutes for electromechanicalcontactors. The working temperature rangeof the LÜTZE relay modules is -40 °C to+70 °C (Class TX acc. to EN 50155).

Scalable network intelligence

managed Ethernet switches (Consist Swit-ches [CS]) within a train segment to securethe communication between all partici-pants, for instance, control units or decen-tral I/O nodes. The topology within anEthernet Consist Network is not specifiedby any specific standard, typically ring to-pologies are used. Due to the fact that atrain can have several train segments(ECNs), these are also connected via thecross-vehicle ETB by means of intelligentLayer-3 switches.

How can individual shielded vehiclesegments (ECN) communicate withother segments?

Ethernet as a communication bus in railvehicles – has now become a realityIt is now a reality! Ethernet is now used inrail vehicles across the globe, initially in thepassenger information and infotainmentlevel and now at the control level. Accor-ding to the definition of Train Communica-tion Network (TCN) in the standardsIEC61375-2-5 and IEC61375-3-4, the so-called Ethernet Train Backbone (ETB) re-places the soon-to-be-obsolete train busWTB and the Ethernet Consist Network re-places the previous MVB or CAN field busnetworks. The communication protocolbetween the bus participants is implemen-ted with the Train Real Time Data Protocol

(TRDP). This network protocol is IP-basedand, thanks to the new structure, allows di-rect communication between all networkparticipants. However, this developmentgoes hand-in-hand with a fundamental pa-radigm shift: a new network topology.

What are the special features of the newtopology?

Managed Ethernet switches are requiredfor implementation; these not only need tosatisfy the feature set known in industrialautomation, but also requirements fromthe rail industry. Bus participants (End De-vices [ED]) are connected to the ECN via

Lütze Transportation GmbH presents a new and innovative family of Ethernet swit-ches that can cover all complexity and hierarchy levels on rail vehicles and combineskey factors of size, durability, price and flexibility in one.

Using a network address translation (NAT) function, the net-work participants of the Consist are invisible to the outside.This is achieved by masking incoming IP addresses and trans-lating them internally. This is how data from the vehicle(ETB) with the IP address 10.10.1.0 and 255.255.255.0 arri-ves; the NAT router translates this into a local IP address,e.g. 192.168.10.0 / 255.255.255.0, that is assigned to a vehi-cle control unit. As soon as the processed data is available inthe control unit, it is sent to the NAT router. The routertranslates the network address of the control unit and sendsthe data with the IP address 10.10.1.0 to the counter-point,e.g. decentral I/O nodes.

As a result of the continuous translation of the IP addresses,the ECN network participants become invisible for partici-pants outside the ECN. Consequently, outside third parties

cannot access the controllevel of the vehicle. The address translationfunction has positive secon-dary effects on the availabilityand configuration of IP addres-ses. In a multi-section vehiclewith duplicated ECNs, networkconfigurations need to be made manuallywithout a 1:1 NAT. This is time-consumingand cost-intensive. If all networks are ma-naged centrally, steps must be taken to en-sure that the IP addresses have only beenissued once. Networking and user-friendli-ness are important criteria for cost-effectiveinstallation when configuring the network.What requirement profile does an Ethernetswitch for rail vehicles need to meet?

Rail compatibilityAn Ethernet switch that is to be installedin a rail vehicle network needs to fulfil therequirements from the EN50155 norm, de-monstrating durability in harsh environ-ments.

ReliabilityAn important characteristic of an Ether-net switch is excellent reliability. Unsche-duled maintenance work and pooravailability can become very expensive forthe train operator.

AvailabilityIf individual network segments fail due todefects, it is important to keep the networkoperational via a redundant path, e.g. viaring redundancies such as RSTP (RapidSpanning Tree Protocol).

Simple handlingThe design, integration and maintenance ofEthernet-based networks must be carriedout quickly, securely and reliably. Duringthe commissioning phase or scheduledmaintenance work, it is important that theconfiguration can be made without theneed for any special software; ideally itshould be possible to clone a configurationfrom one device to the other.

Network securityA firewall can screen and protect the net-work from external influences, such as un-intentional installation mistakes and anyresulting connection to the infotainmentlevel which could initiate criminal attackse.g. cyber attacks. It is essential that thecontrol level in the vehicle is shielded.

All properties are implemented in one deviceThe new Ethernet switch product familyfrom LÜTZE-LEOS stands for Lütze Ether-net Onboard System. The devices werespecially developed for use in rail vehiclesand comply with EN50155. All productshave a wide-range power supply rangingfrom DC 24 V to 110 V and protection classIP54.

Andreas Schindler - Product Manager LÜTZE Transportation GmbH

Technology” es for Rail Technology

LÜTZE TRANSPORTATION has expanded its 'Indication Tech-nology' product range to include configurable and universal Piezosignal encoders PST.

Thanks to its DC 24 - 110 V wide range input, the new Piezo signalencoder PST from LÜTZE TRANSPORTATION can be used acrossthe world in all networks both in diesel and also electrical vehicles.Railway manufacturers and operators can use the LÜTZE PST to pro-gramme warning signals individually. Volume, frequency range andthree operating modes can be configured, either by LÜTZE or the cus-tomer. The Piezo signal encoder is ideal for retrofitting or as a newinstallation in driver's cabs and passenger areas. The programmablePiezo signal encoder can be configured intuitively and easily via theLÜTZE Piezo Configurator Tool. The Piezo signal encoder PST is avai-lable in three different installation models for Din rail and alternativelyfor wall or rear wall mounting.

Warning signals in rail technology have a long life span

Many locomotive drivers and train attendants have become accus-tomed to certain acoustic fault and warning signals over the years;these tones have practically become fundamental audiophile features.In the case of retrofitting or when an existing warning signal encoderis replaced, the question that needs to be addressed is how the fami-liar warning signal can be 'recreated'.

The advantage of the PST warning signal encoder from LÜTZETRANSPORTATION is that it now offers the opportunity to achievecustomised warning signals. Configuration with the free LÜTZEPiezo Configurator Tool is easy to use and allows a variety of settings.There are ten volume levels to choose from. The maximum soundpressure is 96 decibels at a distance of 1 metre. This means that war-ning signals can be unmistakably heard even if there is a lot of back-ground noise. As a comparison, a pneumatic drill produces 80decibels. The frequency range of the PST warning signal encoder canbe set between 200 and a maximum of 4,000 Hertz.

18

As a third option (see Fig. 3), the alterna-ting mode can be set in which two frequen-cies alternate. Both frequencies are eachconfigured with an optional total run-timet1 and individual run-times t2, t3.

Simple handling and multiple installa-tion properties

The LÜTZE signal encoder has a sturdy andcompact aluminium casing and can bemounted in one of three ways: On the Dinrail in the driver's cab, onto the wall in the

locomotive, for example,. as a fire signalencoder in the machine room, or mountedto the rear wall, for example, near the pas-senger doors.

Users of the LÜTZE ZR time relay andLCON converter can also use their USBprogramming cable to programme theLÜTZE PST signal encoder.

The PST warning signal encoder can beused at temperatures of between -40 °C and+70 °C and satisfies the standards and spe-

The operating modes of the LÜTZEPiezo signal encoder PST

There are three different operating modesavailable for the signals: Continuous mode,with a frequency f1 and an optional runtime t1. (see Fig. 1).

In the interval mode an impulse pausemode can be set. The frequency f1 is con-figured for an optional total run-time t1with on times t2 and off times t3 (see Fig. 2).
