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 shuttle-train control PZS-2 is designed to be operated according to

the instructions in this manual in model building, especially with model
railways. Any other use is inappropriate and invalidates any guarantees.

The PZS-2 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.

Caution:

The PZS-2 contains integrated circuits. These are very sensitive to
static electricity. Do not touch components without first discharging
yourself. Touching a radiator or other grounded metal part will
discharge you.

( page 20) and one PCB or

 one ready-built module or
 one ready-built module in a housing (complete unit),
 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).

For testing the module you need an electric light bulb.

In order to connect the module you need wire. Recommended
diameters: > 0.25 mm² for all connections.

It is recommended to connect two push-buttons when programming
the module (e.g. push-buttons item no. 85-5212x, x=1,2,3,6,7).

When connecting points at terminus station 2, you need for switching
the points:

 a bistable relay 12 V (e.g. item no. 84-61111) or

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.

 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.

PZS-2 English

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.

 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.

Page 7

English PZS-2

 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

Traffic between two terminus stations

The module controls the shuttle-train traffic between two terminus
stations of an analogue d.c. model railway layout. At the second
terminus station points can be connected. This allows the alternating
traffic of two trains on the shuttle-train section. One additional stop can
be added in each direction of traffic between the terminus stations.

The shuttle-train traffic runs automatically. The trains are slowed down
before reaching the terminus sections or the two stops as soon as a
track busy indicator integrated into the module indicates the train
coming into the respective section. The further course (braking, halting
and accelerating) is time controlled.

Extra halts

Independent of the automatically running shuttle-train traffic between
the terminus sections (and the two stops), extra halts can be
incorporated with external circuits at any time and place.

Settings for the automatic operation
The traffic

 between the terminus stations
 between the terminus stations and the stops
 between the terminus stations, the stops and/or the extra halts

always runs in four phases: acceleration, normal speed, braking and
halt. The length of the phases acceleration, braking and halt can be
programmed

 individually for each of the two terminus stations
 individually for each of the two stops
 jointly for all extra halts.

Page 9

English PZS-2

The length of the phases is adjusted at a trimmer, the settings are
saved in an IC.

Manual operation

The halt at the terminus stations, the stops and the extra halts can be
prolonged by connecting the corresponding input of the module to
earth. Then the train stops at the next station, stop or halt as long as
the input is connected to earth (at least so long as programmed for the
particular halt). This allows intervention in the automatic shuttle-train
traffic via a switch or an external extra circuit.

The already mentioned extra halts are released as soon as the
corresponding input of the module is connected to earth. This can be
done at any time, regardless in which position of the shuttle-train
section the train is. There are a whole range of applications for this,
e.g.:

 effectuating extra halts along the shuttle-train section or
 effectuating of signal stops or
 triggering exact halts at defined positions (e.g. at the end of a

platform).

To trigger additional halts, several external circuits can be used, e.g.
manually released swiches, couplings with reed contacts or light
barriers or complex signal control circuits.

Overcurrent protection

A fuse integrated in the PZS-2 interrupts the current circuit with
overload or when a short circuit occurs on the rails and thus protects
the module from damage. The fuse is designed as a self-closing fuse
which heats with overload and re-activates the module automatically
after cooling.

Power supply

The module has to be supplied via a transformer not in use as driving
transformer. Note: Driving transformers providing an additional output
for further accessories are not suitable to supply both rails and module,
as they internally contain only one transformer. Note: It is possible to
supply the module via a transformer used to supply other accessories
as the rails (e.g. lighting).

When connecting the module to a transformer in use as driving
transformer, short circuits occur within the PZS-2 which may damage it
irreparably. The integrated fuse is without effect on these short circuits.

The seperate supply of module and rails has the advantage that the
driving voltage can be set individually. E.g. the maximum driving
voltage for the shuttle-train traffic (and the maximum speed with full
speed) can be (pre-) set individually.

Example for a shuttle-train
traffic controlled by a PZS-2

In order to use the PZS-2 it is
sufficient to connect the two
terminus stations. All other
extensions are optional.

By connecting a second rail at
terminus station 2 it is possible to
run two trains alternatingly. In
order to switch between the two
rails an extra bistable relay (not
included in the package) has to be
mounted.

The additional stops 1 (outward
bound) and 2 (return) are
independent of each other. This
allows a different routeing for
outward and return journey (which
is not obligatory).

Extra halts (e.g. at signals or
further stops) can be mounted at
any point of the route. To release
the stop you need a switch or
another external circuit switching
against earth.
