EMC declarationThis product is developed in accordance with the European standardsEN 55014 and EN 50082-1, tested corresponding to the EC - directive89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) andmeets legal requirements.

To guarantee the electromagnetic tolerance you must take thefollowing precautions:

§ Connect the transformer only to an approved mains socket installedby an authorised electrician.

§ Make no changes to the original parts and accurately follow theinstructions, circuit diagram and PCB layut included with this manual.

§ Use only original spare parts if you have to repair the kit or theready-built module.

Operation overviewThe s88-Booster reduces the interferences occuring during data transferfrom the s88-feedback modules to the receiver (central unit, PC viainterface or memory). Interference is caused by external electricalsignals such as:

§ switching impulses for points or§ digital signals in data lines running in parallel to the bus lines.

This interference affects the data transfer and causes faulty input to thereceiver.

Because it is standard to operate the s88-bus with a voltage of 5 Vinterference voltages of 2,5 V can cause interference in data transfer.The longer the s88-data lines are, the higher is the risk of interference.

The s88-booster is connected between receiver and s88-module(s) andheightens the s88-bus´s supply voltage to 12 V. In consequenceinterference voltages of less than 6 V have non influence on the datatransfer in the s88-bus.

English S88-2

Page 24

!

Most commercial s88-feedback modules (e.g. from Littfinsky, Märklin,Viessmann, Tams) operate with this higher supply voltage.

Caution:

Before installing the s88-booster you must check if the s88-feedbackmodules used in your model railroad layout can operate with a supplyvoltage of 12 V. You can determine this by checking the IC-types usedon the feedback modules.

Modules with ICs with a type designation starting with number „74“:These modules are not suitable to use with the s88-booster.Highering the supply voltage to 12 V on the s88-booster would damagethese modules.

Modules with ICs with a type designation containing the numbers„4014“ and „4044“: These modules are OK to use with the s88-booster.

Checking the package contentsCheck the contents of the package for completeness immediately afterunpacking:

§ one kit, containing the components listed in the parts list (see pageI) and one PCB or

§ one ready-built module,§ one 6-core ribbon cable with plugs,§ one manual.

Required tools and consumablesMake sure you have the following tools, equipment and materials readyfor use:

§ an electronic soldering iron (max. 30 Watt) with a fine tip,§ a soldering iron stand,§ a tip-cleaning sponge,§ a heat-resistant mat,§ a small side cutter and wire stripper,§ a pair of tweezers and long nose pliers (not necessary for the

ready-built module),§ tin solder (0,5 mm. diameter),§ wire (diameter: > 0,25 mm² for all connections).

Safe and correct soldering

Caution:

Incorrect soldering can cause dangers through fires and heat. Avoidthese dangers by reading and following the directions given in thechapter Safety instructions. If you have had training in soldering youcan skip this chapter.

English S88-2

Page 26

§ Use a small soldering iron with max. 30 Watt. Keep the soldering tipclean so the heat of the soldering iron is applied to the solder pointeffectively.

§ Only use electronic tin solder with a flux.§ When soldering electronic circuits never use soldering-water or

soldering grease. They contain acids that can corrode componentsand copper tracks.

§ Solder quickly: holding the iron on the joints longer than necessarycan destroy components and can damage copper tracks orsoldering eyes.

§ Observe correct polarity orientation of semi-conductors, LEDselectrolytic capacitors and integrated circuits before soldering andensure that the solder time does not exceed 5 seconds, otherwisecomponents can be damaged.

§ Apply the soldering tip to the soldering spot in such a way that the partand the soldering eye are heated at the same time. Simultaneously addsolder (not too much). As soon as the solder becomes liquid take itaway. Hold the soldering tip at the spot for a few seconds so that thesolder flows into the joint, then remove the soldering iron.

§ Do not move the component for about 5 seconds after soldering.§ To make a good soldering joint you must use a clean and

unoxidised soldering tip. Clean the soldering tip with a damp pieceof cloth, a damp sponge or a piece of silicon cloth.

§ Cut the wires after soldering directly above the PCB solder side witha side cutter.

§ After placing the parts, please double check for correct polarity.Check the PCB tracks for solder bridges and short circuits createdby accident. This would cause faulty operation or, in the worstcase, damage. You can remove excess solder by putting a cleansoldering tip on the spot. The solder will become liquid again andflow from the soldering spot to the soldering tip.

Assembling the kitYou can skip this part if you have purchased a ready-built module.

Preparation

Put the sorted components in front of you on your workbench. Theseparate electronic components have the following special features youshould take into account to prevent mistakes in assembling:

Resistors

Resistors reduce current. Their mounting orientation is of noimportance. The value of resistors for smaller power ratings(under 5 W) is indicated through colour rings. Every colourstands for another figure. The colour ring in brackets indicatesthe tolerance of the resistor which here is of no importance.

Value Colour rings1 kΩ brown - black - red (gold)

Capacitors

Among other things capacitors are used for filtering interferencevoltages or as frequency determining parts. Ceramic capacitorsare not polarized, for that reason their mounting orientation isof no importance. Normally they are marked with a three-digitnumber which indicates the value coded.

Value Number

100 nF 104

Electrolytic capacitors

Electrolytic capacitors are often used to store energy. Incontrast to ceramic capacitors they are polarized. One of thetwo leads is marked with a minus sign which indicates themounting orientation. The value is given on the casing.

Electrolytic capacitors are available with different voltagesustaining capabilities. Using an electrolytic capacitor with a

English S88-2

Page 28

voltage sustaining capability higher than required is alwayspossible.

Diodes

Diodes allow the current to pass through in one direction only(forward direction), simultaneously the voltage is reduced by0,3 to 0,8 V. Exceeding of the limit voltage always will destroythe diode, and allow current to flow in the reverse direction.

The diode type is printed on the body.

Diodes must be mounted in a given direction. The negativeend is marked with a ring. This is shown in the PCB layout.

Zener diodes

Zener diodes are used for limiting voltages. In contrast to„normal“ diodes they are not destroyed when the limit voltageis exceeded.

Rectifiers

Rectifiers convert alternating into direct voltage, they havehardly no influence on the level of the voltage. They have fourpins: two for the input voltage (a.c. voltage) and two for theoutput voltage (d.c. voltage). The pins for the output voltageare polarized. The pin connections are printed on the housing.As usual with wired components the longer connecting pin isthe positive pole.

Integrated circuits (ICs)

Depending on the type, ICs fulfil various tasks. They arepolarized and therefore have to be mounted in a certaindirection. The most common housing form is the so-called"DIL"-housing, from which 4, 6, 8, 14, 16, 18 or more "legs"(pins) are arranged along the long sides. The mountingorientation is shown by a semicircular or circular marking atthe end of the housing, which is also shown on the PCBlayout.

S88-2 English

Page 29

!

ICs are sensitive to damage during soldering (heat,electrostatic charging). For that reason in the place of the ICsIC sockets are soldered in, in which the ICs are inserted later.The mounting orientation of the sockets is preset as well. Themarkings on the PCB, the socket and the IC must lie on top ofeach other after mounting.

Voltage regulators

Voltage regulators are ICs, which convert a variable, nonregulated input voltage in a constant output voltage. They areproduced in transistor housings with three connecting pins forinput, output and earth.

With voltage reuglators in a flat TO-housing the unlabelledmetallic rear is marked by a thick line on the PCB layout.

Terminal strips

Terminal strips are solder-in screw-type terminals. They provide asolder-free and safe connection of the cables to the circuit, which canstill be seperated any time. When several terminal strips have to bemounted side by side, they have to be put together before mounting.

Assembling the kit

Start the assembly with the resistor and the diodes. First solder thecomponents on the solder side of the PCB and then cut the excesswires with side cutters, as short as possible.

Then insert and solder in the IC-sockets The socket must be mountedaccording to the marking on the PCB. Continue the assembly with therectifier, the capacitors, the voltage regulator and the electrolyticcapacitors.

Caution:

Diodes, ICs, rectifiers, voltage regulators and electrolytic capacitorsmust be mounted in the right direction! If you solder them the wrongway around the affected parts can be damaged when you connect the

English S88-2

!

power. In the worst case the whole circuit can be damaged, and at thebest, a wrongly connected part will not function.

Next solder the terminal strips and the solder pins. Join the terminalstrips together before soldering.

Finally, insert the ICs into the soldered IC-sockets.

Caution:

Do not touch the ICs without first discharging yourself by touching aradiator or other grounded metal parts. Do not bend the "legs" of theICs when inserting them into the sockets. Check that the markings onthe PCB, the socket and the IC are in the same direction.

Performing a visual checkDue to material defects and / or improper assembly there may be risksof injury. Transport damage to ready-built modules is also possible. Soyou must perform a visual check after the assembly or after unpackingthe module.

Caution:

Do not power up the module yet.

The following points are inapplicable if you have purchased a ready-built module.

§ Remove all loose parts, wire ends or drops of solder from the PCB.Remove all sharp wire ends.

§ Check that solder contacts which are close to each other are notunintentionally connected to each other. Risk of short circuit!

§ Check that all components are polarised correctly.

When you have remedied all faults, go on to the next part.

Performing a functional test andconnecting the s88-booster

Please note:

Before installing the s88-booster you should check if the s88-feedbackmodules used in your model railroad layout are compatible with avoltage supply of 12 V and so with the s88-booster. Please note thesection „Operation overview“!

Checking the s88-feedback modules

You should check if the s88-feedback modules are working properlybefore connecting them to s88-booster. See the manual for the s88-feedback modules. That way you can prevent faults occuring afterinstalling the s88-booster due to the s88-feedback modules. Avoidinterference caused by external electrical signals during the funtionltest.

Connecting the s88-booster

Disconnect the first s88-feedback module from the receiver (centralunit, interface, memory). Next connect the s88-booster to the receiverand the first s88-feedback module. Follow the connections diagramfig. 2.

Caution:

The connections for the receiver and the s88-feedback module mustnot be mixed up! If you connect the receiver to the terminal for thes88-feedback module and the s88-feedback module to the terminal forthe receiver, damage to the connected devices may occur when startingup!

Finally connect the s88-booster to it´s power supply.

English S88-2

Page 32

!

! Caution:

The s88-booster must be supplied by a transformer of it´s own. In casethe s88-booster is connected to a transformer that also supplies otherparts of the layout, short-circuits and damages at the s88-boostercannot be excluded.

At last perform a function test on the connected s88-feedback modules.

FAQ§ Parts are getting too hot and/or start to smoke.

Disconnect the system from the mains immediately!

Possible cause: one or more components are soldered incorrectly.à Perform a visual check.

§ The receiver (central unit, interface, memory) does not recieve datafrom the s88-feedback module.Possible cause: The power supply of the s88-booster has beeninterrupted. à Check the connection.Possible cause: The IC on the s88-booster´s PCB has beenmounted the wrong way about. à Check the polarity.Possible cause: The connections of the receiver and the s88-feedbackmodules have been mixed up. à Check the connections. In this case itis possible the connected devices having been damaged. Check thesewithout connecting them to the s88-booster.
