▶ For further information on compatibility, see online www.Z21.eu.
2.3 Kragtoevoer vir die Z21 Digitale Sentrum
As 'n kragtoevoer vir die Z21 Digitale Sentrum, gebruik asseblief uitsluitlik die meegeleverde wisselstroomadapter (Art. Nr. 10851). Moet beslis nie 'n wikkelkerntransformator gebruik nie!
Met die Z21 Digitale Stelsel kan jy die volume verandertage applied to your system at any time by software.
For this purpose, change to the menu “Z21 Settings” in the Z21 mobile app. Always make sure to stay in 11 to 23 V range. Typical voltage ranges are from 14 to 18 V (for the gauges H0 and TT) and approx.12 V (for the gauge N).
Maksimum insette voltage vir die Z21 Digitale Stelsel is 24 V. Die maksimum spoorvolumetage is altyd 1 V onder die insetvolumetage.
Die Z21 Digitale Sentrum is ontwerp vir ladings van tot 3.2 A. Indien gereelde kragonderbrekings in die stelsel voorkom as gevolg van oorbelasting, installeer asseblief 'n booster (sien Bladsy 46).
Let wel: To find out the current power consumption of your system, check the menu point “Power Centre” in the “Z21 Settings” menu of the Z21 mobile app.
Waarskuwing: Positively do not connect the Z21 Digital Centre to ROCO ampVerligters Art. Nrs. 10761 en 10764! Gebruik hierdie komponente slegs op elektries geskeide uitlegonderdele wat slegs deur oorgangsbane verbind is.
Let wel: How to compute the power consumption of an H0 system:
▶ Stationary locos with light: approx. 100 mA
▶ Travelling locos depending on size and load: 300 – 600 mA
▶ Illuminated coaches: approx. 30 mA per minibulb (expect considerable fluctuations!)
▶ Digital coupling or smoke generator: approx. 100 mA
▶ Digital switch drive or switch decoder: approx. 500 mA as reserve
Let wel: Easy programming of your loco decoder
▶ Place loco onto programming track
▶ Start the Z21 mobile app
▶ Switch to programming mode
▶ Enter the new parameters
▶ Ready!
2.4 Werking van Digitale Lokomotiewe
The Z21 Digital System is suitable for the control of all locomotives using ROCO loco decoders or any DCC-compatible decoders. Your Z21 Digital System can administer up to 9,999 loco decoders. The preconfi guration by the factory of all ROCO and Fleischmann locos is decoder address 3. If you use several locos on your system simultaneously, you need to assign a separate decoder address to each one.
With the Z21 Digital System, this is very simple: put the locomotive as the only loco onto the programming track. Select the locomotive on Z21 mobile app and give it a name and decoder address not yet assigned in the programming mode. That’s it!
Alle magnetiese items (skakelaars, ontkoppelspore, seindekodeerders) wat met 'n digitale dekodeerder toegerus is, kan net so maklik met die Z21-mobiele toepassing geprogrammeer en beheer word.
2.5 Opgradering van Analoog Lokomotiewe
Locomotives and components without decoder cannot be used in the Z21 Digital System.
Due to the entirely different voltagDie gebruik van 'n lokomotief sonder 'n dekodeerder lei tot 'n hoogs irriterende hoëfrekwensiegeraas. Daarbenewens is daar 'n risiko dat die motors beskadig sal word.
Baie analoogmodelle kan egter met lokomotiefdekodeerders toegerus word en sodoende geskik gemaak word vir gebruik op jou Z21-uitleg. Met lokomotiewe met 'n vrye gleuf en 'n operasionele digitale koppelvlak is dit baie eenvoudig en maklik, want as 'n reël hoef die dekodeerder bloot in 'n vrye sok ingeprop te word.
2.6 Herstel van die Z21 Digitale Sentrum
If your digital system no longer operates flawlessly, please reset your Z21 Digital Centre to the factory setting as follows:
▶ Press the stop key on the front of the unit.
▶ Keep the key depressed for 5 seconds. The LED light starts flashing in purple.
This shows the Z21 Digital Centre has been reset to the factory setting. If the digital system still does not operate flawlessly, contact your dealer.
2.7 Opdatering van Z21 Digitale Sentrum
Wanneer jou slimfoon of tablet-rekenaar aan die internet gekoppel is, kan jy vir toepassings en die Z21-firmware soek in die "Opdaterings"-afdeling van sagteware-opdaterings by die AppStore en Google Play.
Let wel: You can have your locomotives converted in a professional workshop.
For a list of recommended suppliers, see www.ROCO.cc/en/service-partner.
Waarskuwing: Locomotives and components without decoder cannot be used on the Z21 Digital System.
Let wel: The firmware of your Zimo loco decoder can be updated very conveniently via the programming track. For this purpose, simply drive the respective locomotive to the programming track. In the Z21 mobile app, switch to programming mode and select the menu item “Decoder Update.
Waarskuwing: Only one loco can be read out and/or programmed at the same time.
Let wel: When setting the length of the programming track, take the longer tenders of steam locomotives into account!
2.8 Programmering en Uitleesbaan
Solank jy een enkele lokomotief-dekodeerder wil programmeer, kan jy dit direk op die hoofspoor programmeer. Vir hierdie doel, merk eenvoudig die lokomotief in die Z21 mobiele toepassing, skakel oor na programmeringsmodus en verander die verlangde parameters.
Indien u die dekodeerderinstellings wil lees of nie meer die dekodeerderadres ken nie, beveel ons die gebruik van 'n aparte programmeringsspoor aan.
You can use any partial section of your layout as a programming track – simply isolate it on both ends with insulated rail connectors (Art. Nos. 42611, 61192, 6433 or 9403) or separator rails and then connect it to a power supply element (Art. No. 61190) at the “Prog Track” socket of the Digital Centre.
To program a loco, simply drive it to the corresponding track section. Then change your Z21 mobile app to programming mode (for details, see www.z21.eu). The Z21 Digital Centre now switches the track automatically into programming and read mode.
You can now read the decoder data of the locomotive in the Z21 mobile app via RailCom© and set new CV values for the locomotive. For details, also see www.z21.eu.
2.9 Terugvoer by Programmering en Hoofbaan
Indien die kragverbruik 2.5 A oorskry, is die gedeelte oorlaai en moet dit verdeel word.
Waarskuwing: The booster and the Z21 Digital Centre must not be operated with the same transformer or AC adaptor!
Maak seker dat die spore by die wissels dieselfde polariteit het om kortsluitings te vermy wanneer oor die skeidingswissels gery word. Maak seker dat aangedrewe spore geen kapasitors het nie.
Driving with a Booster
Wanneer jou stelsel gereeld afskakel sonder dat 'n lokomotief of wa ontspoor het of in die afwesigheid van 'n bedradingsfout, dui dit gewoonlik op 'n oorlading as gevolg van te veel kragverbruikers. In hierdie geval sal 'n booster (Art. Nr. 10765) wat ekstra krag aan die uitleg verskaf via 'n ekstra transformator (Art. Nr. 10718, 10725 of 10850) help.
Installasie is eenvoudig:
▶ Subdivide your system into two supply sections having approximately the same power consumption. Separate the tracks on both sides using insulated rail connectors (Art. No. 42611, 61192, 6433 or 9403) or separator tracks.
▶ Attach a power supply element to the new supply section (e.g. geoLine Art. No. 61190) or another separator track and connect it to the “Track Out” socket of the booster.
▶ Now connect the booster to its transformer.
▶ Connect the “Booster In” socket on the booster with the “B Bus” socket of the Z21 Digital Centre. Use the dedicated cable supplied with the booster for this purpose. A detailed cabling diagram is found on Page 47.
You can connect up to three more boosters to the “Booster Out” socket of the booster when necessary. If more than four boosters are needed for your layout, a brake generator (Art. No. 10779) must be connected in place of the fourth booster. Up to four more boosters can then be connected to the “Booster Out” socket.
Let wel: Om seker te maak dat die lusmodule vinnig genoeg reageer, moet die sensitiwiteit voor gebruik ingestel word met behulp van die potensiometer wat aan die kant sigbaar is. Volg die gebruiksinstruksies.
Loops in Digital Operation
Every DC railway enthusiast knows the following problem: if after a loop, the left rail profi le meets the right one, a shortcircuit occurs without the appropriate wiring.
With our loop modules (Art. No. 10767 or 10769), this switching problem in digital operation is elegantly taken care of: simply separate the loop on both sides on two poles and insulate the rest using insulated connectors (Art. No. 42611, 61192, 6433 or 9403) electrically from the remainder of the layout (see Page 49). The separated layout portion within the loop must be longer than the longest train which is to drive through the loop. The power to the loop is supplied by the loop module which is connected either to the track outside the loop or to the Z21 Digital Centre.
And this is how the loop module works: as soon as a train enters the loop regardless of the direction, shortcircuit detection occurs in the module. The polarity in the loop is automatically changed before the shortcircuit detection of the Digital Centre is aware of it or before the trains slows down. The polarity reversal is repeated when the train leaves the loop. Thus, the train can pass through a loop without stopping or operator ingryping.
