Mechanical hazards
Cut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the PCB.
Visibly damaged parts can cause unpredictable danger. Do not use
damaged parts: recycle and replace them with new ones.
Electrical hazards
§Touching powered, live components,
§touching conducting components which are live due to malfunction,
§short circuits,
§connecting the circuit to another voltage than specified,
§impermissibly high humidity,
§condensation build up
can cause serious injury due to electrical shock. Take the following
precautions to prevent this danger:
§Never perform wiring on a powered module.
§Assembling and mounting the kit should only be done in closed,
clean, dry rooms. Beware of humidity.
§Only use low power for this module as described in this manual and
only use certified transformers.
§Connect transformers and soldering irons only in approved mains

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.
In schools, training centres, clubs and workshops, assembly must be
supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.

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.
English S88-2

!
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.

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.
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.
