1. Getting started
How to use this manual
This manual gives step-by-step instructions for safe and correct
assembly of the kit and fitting and connecting of the ready-built
module, and operation. Before you start, we advise you to read the
whole manual, particularly the chapter on safety instructions and the
checklist for trouble shooting. You will then know where to take care
and how to prevent mistakes which take a lot of effort to correct.
Keep this manual safely so that you can solve problems in the future. If
you pass the kit or the ready-built module on to another person, please
pass on the manual with it.
Intended use
The double flashlights WBA-1, WBA-2 and WBA-3 are designed to be
operated according to the instructions in this manual in model building
and with model railways. Any other use is inappropriate and invalidates
any guarantees.
The double flashlights should not be assembled or mounted by children
under the age of 14.
Reading, understanding and following the instructions in this manual
are mandatory for the user.
Checking the package contents
Please make sure that your package contains:
one kit WBA-1 or WBA-3, containing the components listed in the
parts list (page 12) and one PCB or
one ready-built module WBA-1, WBA-2 or WBA-3,
a CD (containing the manual and further information).

Required materials
For assembling the kit you need:
an electronic soldering iron (max. 30 Watt) or a regulated soldering
iron with a fine tip and a soldering iron stand,
a tip-cleaning sponge,
a heat-resistant mat,
a small side cutter and wire stripper,
as necessary a pair of tweezers and long nose pliers,
electronic tin solder (0,5 mm. Diameter),
thin connecting wire.
2. Safety instructions
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 and connecting the circuit to another voltage than
specified,
impermissibly high humidity and 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.

WBA-1 | WBA-2 | WBA-3 English
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
sockets installed by an authorised electrician.
Observe cable diameter requirements.
After condensation build up, allow a minimum of 2 hours for
dispersion.
Use only original spare parts if you have to repair the kit or the
ready-built module.
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.
Caution:
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.
3. 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.
Use a small soldering iron with max. 30 Watt or a regulated
soldering iron.
Only use electronic tin solder with flux.
When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
Insert the component connecting pins into the PCB´s holes as far as
possible without force. The components should be close to the
PCB`s surface.

WBA-1 | WBA-2 | WBA-3 English
Observe correct polarity orientation of the parts before soldering.
Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or soldering
eyes.
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 soldering joint 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.

4. Operation overview
The double flashlights WBA-1, WBA-2 and WBA-3 have been designed
to control LEDs. The circuit´s two outputs are alternately switched on
and off. Fields of application are e.g. St. Andrew´s crosses, the flash
lights of emergency or roadworks vehicles or signal lamps.
Flashing frequency
The flashing frequency of the double flashlights WBA-1 and WBA-2
cannot be altered. Due to component tolerances it is 1 to 2 Hz. Thus
the time period between two flashes is one to a half second.
With the flashlight WBA-3 the flashing frequency can be set at a
trimmpot to 0,2 to 0,4 Hz. The time period between two flashes is 5 to
0.25 seconds then.
Connecting LEDs
The LEDs are connected directly to the outputs, the required series
resistors are integrated in the circuit. Each output enables the
connection of one LED, two LEDs in parallel or several LEDs in series.
The maximum number of LEDs that can be connected in series to one
output depends on the available voltage and the fluorescent color of
the LEDs.
