Fire risk

Touching flammable material with a hot soldering iron can cause fire, which can result in injury or death through burns or suffocation. Connect your soldering iron or soldering station only when actually needed. Always keep the soldering iron away from inflammable materials. Use a suitable soldering iron stand. Never leave a hot soldering iron or station unattended.

Thermal danger

A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a precaution:

§ use a heat-resistant mat during soldering,

§ always put the hot soldering iron in the soldering iron stand,

§ point the soldering iron tip carefully when soldering, and

§ remove liquid solder with a thick wet rag or wet sponge from the

soldering tip.

Dangerous environments

A working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room with enough freedom of movement.

Other dangers

Children can cause any of the accidents mentioned above because they are inattentive and not responsible enough. Children under the age of 14 should not be allowed to work with this kit or the ready-built module.

Little children can swallow small components with sharp edges, with fatal results! Do not allow components to reach small children.

EMC declaration

This product is developed in accordance with the European standards EN 55014 and EN 50082-1, tested corresponding to the EC - directive 89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) and meets legal requirements.

To guarantee the electromagnetic tolerance you must take the following precautions:

§ Connect the transformer only to an approved mains socket installed

by an authorised electrician.

§ Make no changes to the original parts and accurately follow the

instructions, circuit diagram and PCB layut included with this manual.

§ Use only original spare parts if you have to repair the kit or the

ready-built module.

Operation overview

The s88-Booster reduces the interferences occuring during data transfer from the s88-feedback modules to the receiver (central unit, PC via interface or memory). Interference is caused by external electrical signals 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 the receiver.

Because it is standard to operate the s88-bus with a voltage of 5 V interference 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) and heightens the s88-bus´s supply voltage to 12 V. In consequence interference voltages of less than 6 V have non influence on the data transfer in the s88-bus.

Page 8

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-feedback modules used in your model railroad layout can operate with a supply voltage of 12 V. You can determine this by checking the IC-types used on 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 damage these 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 contents

Check the contents of the package for completeness immediately after unpacking:

§ one kit, containing the components listed in the parts list (see page

I) and one PCB or

§ one ready-built module,

§ one 6-core ribbon cable with plugs,

§ one manual.

Required tools and consumables

Make sure you have the following tools, equipment and materials ready for 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. Avoid these dangers by reading and following the directions given in the chapter Safety instructions. If you have had training in soldering you can skip this chapter.

Page 10

English S88-2

Page 26

§ Use a small soldering iron with max. 30 Watt. Keep the soldering tip

clean so the heat of the soldering iron is applied to the solder point effectively.

§ 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 components and copper tracks.

§ Solder quickly: holding the iron on the joints longer than necessary

can destroy components and can damage copper tracks or soldering eyes.

§ Observe correct polarity orientation of semi-conductors, LEDs

electrolytic capacitors and integrated circuits before soldering and ensure that the solder time does not exceed 5 seconds, otherwise components can be damaged.

§ Apply the soldering tip to the soldering spot in such a way that the part

and the soldering eye are heated at the same time. Simultaneously add solder (not too much). As soon as the solder becomes liquid take it away. Hold the soldering tip at the spot for a few seconds so that the solder 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 piece of cloth, a damp sponge or a piece of silicon cloth.

§ Cut the wires after soldering directly above the PCB solder side with

a side cutter.

§ After placing the parts, please double check for correct polarity.

Check the PCB tracks for solder bridges and short circuits created by accident. This would cause faulty operation or, in the worst case, damage. You can remove excess solder by putting a clean soldering tip on the spot. The solder will become liquid again and flow from the soldering spot to the soldering tip.

Assembling the kit

You can skip this part if you have purchased a ready-built module.

Preparation

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

Resistors

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

Value Colour rings 1 kΩ brown - black - red (gold)

Capacitors

Among other things capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic capacitors are not polarized, for that reason their mounting orientation is of no importance. Normally they are marked with a three-digit number which indicates the value coded.

Value Number 100 nF 104

Electrolytic capacitors

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

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

Page 12

English S88-2

Page 28

voltage sustaining capability higher than required is always possible.

Diodes

Diodes allow the current to pass through in one direction only (forward direction), simultaneously the voltage is reduced by 0,3 to 0,8 V. Exceeding of the limit voltage always will destroy the 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 negative

end 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 voltage is exceeded.

Rectifiers

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

Integrated circuits (ICs)

Depending on the type, ICs fulfil various tasks. They are polarized and therefore have to be mounted in a certain direction. 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 mounting orientation is shown by a semicircular or circular marking at the end of the housing, which is also shown on the PCB layout.

Page 13

S88-2 English

Page 29

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

Voltage regulators

Voltage regulators are ICs, which convert a variable, non regulated input voltage in a constant output voltage. They are produced in transistor housings with three connecting pins for input, output and earth.

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

Terminal strips

Terminal strips are solder-in screw-type terminals. They provide a solder-free and safe connection of the cables to the circuit, which can still be seperated any time. When several terminal strips have to be mounted 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 the components on the solder side of the PCB and then cut the excess wires with side cutters, as short as possible.

Then insert and solder in the IC-sockets The socket must be mounted according to the marking on the PCB. Continue the assembly with the rectifier, the capacitors, the voltage regulator and the electrolytic capacitors.

Caution:

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

Page 14

English S88-2

Page 30

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

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

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

Caution:

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

Performing a visual check

Due to material defects and / or improper assembly there may be risks of injury. Transport damage to ready-built modules is also possible. So you must perform a visual check after the assembly or after unpacking the 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 not

unintentionally 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 and connecting the s88-booster

Please note:

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

Checking the s88-feedback modules

You should check if the s88-feedback modules are working properly before connecting them to s88-booster. See the manual for the s88feedback modules. That way you can prevent faults occuring after installing the s88-booster due to the s88-feedback modules. Avoid interference caused by external electrical signals during the funtionl test.

Connecting the s88-booster

Disconnect the first s88-feedback module from the receiver (central unit, interface, memory). Next connect the s88-booster to the receiver and the first s88-feedback module. Follow the connections diagram fig. 2.

Caution:

The connections for the receiver and the s88-feedback module must not be mixed up! If you connect the receiver to the terminal for the s88-feedback module and the s88-feedback module to the terminal for the receiver, damage to the connected devices may occur when starting up!

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

Page 16

English S88-2

Page 32

Caution:

The s88-booster must be supplied by a transformer of it´s own. In case the s88-booster is connected to a transformer that also supplies other parts of the layout, short-circuits and damages at the s88-booster cannot 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 data

from the s88-feedback module. Possible cause: The power supply of the s88-booster has been

interrupted. à Check the connection. Possible cause: The IC on the s88-booster´s PCB has been

mounted the wrong way about. à Check the polarity. Possible cause: The connections of the receiver and the s88-feedback

modules have been mixed up. à Check the connections. In this case it is possible the connected devices having been damaged. Check these without connecting them to the s88-booster.

If you cannot find the problem, please return the module for repair (address on the cover page).
