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.

Multi-Timer English
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.
Page 7

English Multi-Timer
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 coffe dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions.
Use a soldering iron with temperature control, which you set to
approx. 300 °C.
Only use electronic solder with a flux.
Never use soldering water or soldering grease when soldering
electronic circuits. These contain an acid that destroys components
and conductor paths.
Insert the connecting wires of the components as far as possible
through the holes of the board without using force. The body of the
component should be close above the board.
Make sure that the polarity of the components is correct before
soldering them.
Solder quickly: soldering for too long can coffe pads or tracks to
become detached or even destroy components.
Hold the soldering tip on the soldering point in such a way that it
touches the component wire and the pad at the same time. Add (not
too much) solder simultaneously. As soon as the solder begins to
flow, remove it from the soldering point. Then wait a moment for the
solder to flow well before removing the soldering iron from the
soldering joint.
Page 8
tams elektronik
Multi-Timer English
Do not move the component you have just soldered for about 5
seconds.
A clean, non-oxidised (scale-free) soldering tip is essential for a
perfect soldering joint and good soldering. Therefore, before each
soldering, wipe off excess solder and dirt with a damp sponge, a
thick damp cloth or a silicone wiper.
After soldering, cut off the connecting wires directly above the
soldering point with a side cutter.
After assembly, always check each circuit again to ensure that all
components are correctly inserted and polarised. Also check that no
connections or tracks have been accidentally bridged with tin. This
can lead not only to malfunction, but also to the destruction of
expensive components. You can re-liquefy excess solder with the
clean hot soldering tip. The solder then flows from the board to the
soldering tip.

4. Operation overview
Four outputs
The Multi-Timer has 4 outputs to control downstream circuits. In order
to release the switching operations, the contacts of the 4 related
switching inputs have to be closed. The switching duration can be set
via trim-pots individually for the different switching operations.
Four modes of operation
When used in analogue or digital layouts:
1. time switch
2. pulse delay
3. random switch
When used in analogue layouts:
4. start-brake-stopover switch
Setting the mode of operation
The mode of operation has to be set by means of jumpers. The
operation modes 1 and 2 are set to the 4 outputs of the Multi-Timer
individually. Thus using one Multi-Timer as a combined time switch and
pulse delay is possible. When using one Multi-Timer as a ramdom
switch or a start-brake-stopover switch, the setting is effective for the
whole module.
Operating principle "switch"
The Multi-Timer works like a switch and does not provide current for
the operation of downstream circuits at it´s outputs. Therefore the
downstream circuits have to be provided externally with current. It is
possible to use d.c. as well as a.c. voltage for the power supply.
Page 10
tams elektronik
Multi-Timer English
4.1. Operation mode 1 "Time Switch"
Use in analogue or digital layouts
The activating time has to be set individually at a trim-pot for each
output. The maximum activating time is 4,5 minutes.
After the closure of the contacts of a switching input the related output
is switched on for the set time. In order to release a switching pulse
push-buttons or comparable external circuits can be used.
In this operation mode the Multi-Timer can be set either to allow it to
be retriggered or not.
To be retriggered: When the contacts of the switching input are
closed again (e.g. by activating the push-button again), before the set
time has run out, the time starts to run from scratch again. Example:
When at a set time of 60 seconds the contacts of the switching input
are closed again after 30 seconds, the overall activating time is 90
seconds.
Not to be retriggered: When the contacts of the switching input are
closed again, before the set time has run out, this has no effects. A
new switching operation cannot be released befort the set activating
time has run out.
Application
You can apply the operation mode 1 for all actions you want to be
switched on for a certain time and to be switched off automatically after
the time has run out.
Page 11
tams elektronik
English Multi-Timer
4.2. Operation mode 2 "Pulse Delay"
Use in analogue or digital layouts
The delay time has to be set individually at a trim-pot for each output.
The maximum activating time is 30 seconds.
Each change in state at one of the switching inputs is transmitted to the
related output with the set delay. One change in state is as well an
opening as a closing of the contacts of the switching input. A maximum
of 64 changes in state can be saved within the set time of delay. In
case there are more changes of state within the time of delay, the
changes of state first executed will be deleted.
Application
You can apply the operation mode 2 for all actions that should be
executed with a time delay after a preceding occurance, e.g. opening
the level-crossing after a train has passed or setting the signal to stop
after a train has passed.
The operation mode 2 can be used as well to release switching
operations delayed, in order to prevent switching contacts from being
blocked permanently. Example: The power supply in a rail section has
to be switched off (and the train brought to a stopp), as soon as the
train has passed a reed contact. In case the train would stop
immediately after passing the reed contact, it would be impossible to
switch on the rail section again. With the Multi-Timer it is possible to
Page 12
tams elektronik
Multi-Timer English
delay the switching pulse so that the train does not stop before the
reed contact will not be released any more.
4.3. Operation mode 3 "Random Switch"
Use in analogue or digital layouts
The 4 outputs of the Multi-Timer are switched separately for a time at
random. The time interval after which the random generator decides
whether to release a switching operation or not, can be set for each
output individually via a trimpot, the maximum interval is 4,5 minutes.
The downstream circuit can stay switched on or off for several time
intervals (maximum 10)
When connecting switches (or similar circuits) to the switching inputs of
the Multi-Timer, the random control can be affected manually. As soon
as the contacts of the switching inputs are closed (= on), the current
state of the related output will be "frozen" and the random switch has
no more influence on the output. The output will be controlled by the
random switch only after the contacts of the switching input are opened
again (= out).
Application
You can apply the operation mode 3 for all actions to be switched on
and off at random.
Page 13

English Multi-Timer
4.4. Operation mode 4 "Start-Brake-Stopover Switch"
Use in analogue layouts only
The Multitimer controls
braking, stopping and starting of analogue locomotives (e.g. in a
station or at a signal stop).
optionally: the signal position (stop or clear)
the driving characteristics of a locomotive in the connected rail
section. In conjunction with the PWM it is set to control the
locomtoive´s movement within the rail section.
Length of time for braking, stopping and starting
The length of time for braking, stopping and starting and the supply
voltage when starting has to be set via trim-pots. The maximum time to
be set for stopping is 4,5 minutes, you can reduce or prolong it via a
switch as required. The maximum time for braking and starting is 12
seconds. The supply voltage when starting can be set so that the
locomotive in fact starts without delay, but at a low rate. The maximum
supply voltage is not applied before the end of the starting time.
PWM for locomotive´s motor
It is possible to set either a low or a high PWM for the connected rail
section by corresponding setting of the jumpers. The PWM is the rate
controlling the locomotive´s motor. Whether a low or a high PWM is
more suitable, depends on the individual characteristics of the motor.
low PWM: higher motor output, but loud and possibly disturbed
engine running;
high PWM: lower motor output, but quiet and smooth engine
running.

Multi-Timer English
Sequence
Via a switch connected to switching input 1, the signal is set to "stop"
(switching input closed) or to "clear" (switching input open).
Semaphore signals are to be switched directly, light signals can be
switched via bistable relays as well. It is also possible to do without
connecting signals, the outputs 1 and 2 stay then open.
The switching input 2 is used to release the braking, as soon as the
locomotive passes a contact at the beginning of the braking track and
thus the contacts of the switching input are closed. Here a reed contact
or a hall sensor in combination with a magnet or a photoelectric barrier
can be used.
Depending on the signal position (= switching input 1 closed or open),
the locomotive will brake and stop or drive on. The signal´s change to
"clear" is carried out either
automatically after the set stop time has elapsed or
before the stop time has elapsed by opening the switching input 1.
You can prolong the stop time by closing the contacts at switching input
3. The signal remains on "stop" as long as the input 3 is closed, but at
least for the set stop time.
As soon as the signal turns to "clear", the locomotive starts with the set
starting delay and starting supply voltage.
Example 1: Signal set to "Stop" (switching input 1 closed)
1. When passing the sensor at the beginning of the braking track,
switching input 2 is closed and consequently the braking process is
started. The braking track´s length depends on the time period set for
braking.
In order to guarantee a reliable stop before the signal, you can install
an additional security section switched currentless when the signal is
set to "Stop".
Page 15
tams elektronik
English Multi-Timer
2. The locomotive stops in front of the signal until the hold time has
expired (and switching input 1 has been switched to "open"
automatically) or until switching input 1 has been opened (e.g. by
means of an external switch).
By closing switching input 3 (e.g. by means of an external switch) while
keeping switching input 1 closed at the same time, you can prolong the
hold time and prevent switching input 1 from automatically been
opened after the halting has expired. If switching input 3 is opened
before the set hold time has expired, the automatic operation will be
restarted after the hold time has expired.
Page 16
tams elektronik
Multi-Timer English
Example 2: Signal set to "Clear" (switching input 1 open)
Passing the sensor at the beginning of the braking track has no effect,
the braking process is not started. The state of switching input 3 has
no effects, too.
Hint: If the signal would be set to "Stop" before the locomotive has
passed, it would stop (abruptly) at the signal or in the security section
switched currentless in front of the signal.

6. Assembling the kit
You can skip this part if you have purchased a ready-built module or device.
6.1. 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 in assembling:
Resistors
Resistors reduce current.
The value of resistors for smaller power ratings is indicated
through colour rings. Every colour stands for another
figure.
Carbon film resistors have 4 colour rings. The 4th ring
(given in brackets here) indicates the tolerance of the
resistor (gold = 5 %).
Value: Colour rings:
1 k brown - black - red (gold)
1,5 k brown - green - red (gold)
10 k brown - black - orange (gold)
Trimm-potentiometers
Trimm-potentiometers (abrv. "trimm-pots") are resistors
which allow the value of resistance to be varied and that
way to be adapted to the particular demands. In the
middle they have a small slot into which a small
screwdriver can be put in order to vary the value of
resistance. The maximum value is printed on the housing.
Depending on the mounting situation trimmpots with a lying or a
standing package are used.
Page 20
tams elektronik
Multi-Timer English
Ceramic capacitors
Among other things ceramic capacitors are used for
filtering interference voltages or as frequency determining
parts. Ceramic capacitors are not polarized.
Normally they are marked with a three-digit number which
indicates the value coded.
The number 104 corresponds to the value 100 nF.
Electrolytic capacitors
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. The
value is given on the package.
Electrolytic capacitors are available with different voltage
sustaining capabilities. Using an electrolytic capacitor with
a voltage sustaining capability higher than required is
always possible.
Diodes and Zener 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.
Zener diodes are used for limiting voltages. In contrast to "normal"
diodes they are not destroyed when the limit voltage is exceeded.
The diode type is printed on the package.
Rectifiers
Rectifiers convert alternating into direct 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.
Page 21
tams elektronik
English Multi-Timer
Transistors
Transistors are current amplifiers which convert low signals into
stronger ones. There are several types in different package forms
available. The type designation is printed on the component.
Transistors for a high power rating (e.g. BD types, BT
types) have a flat package (TO-package), which is in use in
different versions and sizes.
The three pins of the field effect transistors (e.g. BS types,
FETs, MOSFETs) are called "source", "gate" and "drain"
(abbreviated with the letters S, G, D in the circuit
diagram).
Integrated circuits (ICs)
Depending on the type, ICs fulfil various tasks. 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.
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.
Microcontrollers
Microcontrollers are ICs, which are individually programmed for the
particular application. The programmed controllers are only available
from the manufacturer of the circuit belonging to it.
Opto couplers
Opto couplers are ICs, which work similar to laser beam switches. They
combine in one housing a light emitting diode and a photo transistor. Their
task is the transmittion of information without galvanic connection. They are
in a DIL-housing with at least 4 pins.
Page 22

Multi-Timer English
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 separated any time.

6.4. Assembly
Proceed according to the order given in the list below. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutter. Follow the instructions on soldering in
section 3.
Caution:
Several components have to be mounted according to their polarity.
When soldering these components the wrong way round, they can be
damaged when you connect the power. In the worst case the whole
circuit can be damaged. At the best, a wrongly connected part will not
function.
1. Resistors Mounting orientation of no importance.
2. Diodes, Zener

mounting them.
11. ICs in DILhousing
Insert the ICs into the soldered socket.
Do not touch the ICs without first discharging
yourself by touching a radiator or other
grounded metal parts.
Do not bend the "legs" when inserting them
into the sockets. Check that the markings on
the PCB, the socket and the IC show to the
same direction.
6.5. Performing a visual check
Perform a visual check after the assembly of the module and remove
faults if necessary:
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.

7. Connecting the Multi-Timer
7.1. Functional test
Especially, when you have mounted the Multi-Timer from a kit, you
should perform a functional test before mounting it in your layout.
Connect an electric bulb with a separate power supply to output 1
(connections 1 and 2) and a push-button to switching input 1
(connection 9) as described in section 7.3 for operation mode 1.
Connect the Multi-Timer to the power supply.
Choose operation mode 1 (r) for testing all outputs, so do not insert a
jumper to any of the solder pins (→ section 8). Set a short switching
time (trim-pot as far as it will go to the left). Then check all four
outputs and switching inputs one after the other.
Caution:
When a component gets hot, disconnect the module from the power
supply immediately! Risk of short circuit! Check the assembly!

7.2. Voltage supply
You can use a d.c. or an a.c. transformer with 12 to 18 V as a power
supply for the Multi-Timer.
Caution:
Do not use the same transformer for the power supply of the MultiTimer as used for the power supply of downstream circuits or the rails.
The arising stray electric currents could possibly damage the output
transistors of the Multi-Timer.
Caution:
If you use a d.c. transformer for the power supply of the Multi-Timer,
you generally have to respect the polarity when connecting it. If using
an a.c. transformer the polarity is of no importance first.
When connecting several outputs to circuits supplied by the same
transformer, all connections have to be polarized the same way as a rule.
Otherwise a short circuit could occur damaging connected devices.

Connection to the outputs (operation modes 1, 2 and 3)
The Multi-Timer works like a switch. It does not provide current for the
operation of downstream circuits at it´s outputs. That is why these
need an external voltage supply (d.c. or a.c.).
When using the Multi-Timer with operation modes 1, 2 or 3 (as time
switch, pulse delay or ramdom switch), connect the downstream
circuits to the four outputs according to your needs.
Connection to the switching inputs (operation modes 1 and 2)
As soon as the contacts of the switching inputs are closed, the
switching operations will be released at the related outputs.
For the operation modes 1 or 2 you have to connect push-buttons to
the switching inputs. As an alternative you can mount upstream circuits
releasing a short switching pulse – like push-buttons.
Connection to the switching inputs (operation mode 3)
In order to affect the random control manually, you have to connect
switches (or circuits with a similar mode of operation) to the switching
inputs. As soon as the contacts of the switching inputs are closed, the
previously by the random switch set state will be "frozen".

Multi-Timer English
7.4. Connection with operation mode 4
For use as a start-brake-stopover switch you have to isolate the rail
section to be controlled by the Multi-Timer from the remaining layout.
These can be e.g.:
rail sections with a signal stop (e.g. block sections)
flag stops
Here cut with 3-rail systems the middle conductor and with 2-rail
systems the same conductor you have cut for other applications. In
addition, you can cut off a security section switched currentless when
the signal is set to "Stop".

9 Switching
input 1
Switch for toggling between signal position
"clear" (= open) and "stop" = closed
You can connect any upstream circuits working
according to the principle of a switch and toggling
between the two signal positions. When using
instead of a solenoid article with double coil drive
(e.g. semaphore signal) a light signal, you have to
mount an additional bistable relay.
10 Switching
input 3
Switch, push button or upstream circuits
The locomotive stops as long as the switching
input is closed, but at least for the set stop time.
11 Switching
input 2
Push button, reed contact, Hall sensor,
photoelectric barrier or similar to release the
braking operation
When switching input 1 is closed simultaneously
(signal to "stop"), the braking operation will be
released as soon as the contacts of switching
input 2 are closed at at switching pulse.

8. Setting the Multi-Timer
Setting the operation mode
You can set the following operation modes on your Multi-Timer by
inserting jumpers to the solder pins JP2 to JP5:
1. time switch
2. pulse delay
3. random switch
4. start-brake-stopover switch
The Multi-Timer reads in the currently set operation mode immediately
after having been switched on. If altering the order of the jumpers after
the switching on, this has no effect until the Multi-Timer has been
switched off and on again.
The operation modes 1 and 2 have to be set on the 4 outputs
separately. Therefore you can use the Multi-Timer as a combined time
switch and pulse delay. With the operation modes 3 and 4 the setting is
valid for all four outputs.
With the operation mode 1 "time switch" you can choose whether you
want to retrigger the outputs or not. For the operation mode 4 "startbrake-stopover switch" you have to define either a low or a high PWM
for the locomotive motor.

Setting the switching times
You set the swtching times and with operation mode 4 the starting and
braking delay as well as the voltage supply when starting at the four
trim-pots related to the outputs. When setting the trim-pot as far as it
will go to the right you will define the maximum value.
Please notice that with operation mode 3 "random switch" not the
maximum toggling time is set, but the time interval, which elapses
before the Multi-Timer decides at random if to toggle the output or
not.

9. Check list for troubleshooting
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 In case you have mounted the module from a kit, perform a
visual check (à section 6.) and if necessary, remedy the faults.
Otherwise send in the module for repair.
There is no reaction after releasing a switching operation.
Possible cause: The push-button, the switch or the circuit used to
close the contacts of the switching input are defective or connected
incorrectly. à Check the push-button, the switch or the circuit and
the connections.
Possible cause: The downstream circuit is defective or connected
incorrectly. à Check the circuit and the connections. In this case you
should exchange the circuit by an electric bulb for a test and set
operation mode 1 for the output concerned.
With use as a start-brake-stopover switch
The locomotive does not start although the signal has been set to
"clear" / the stopping time has elapsed.
Possible cause: The PWM is set to "high", but the voltage at the
track is not sufficient for the locomotive. à Alter the setting to "low
PWM".
The locomotive´s engine running loud and disturbed.
Possible cause: A low PWM has been set. à Alter the setting to
"high PWM". Notice: Possibly the locomotive does not run with these
settings as the track voltage is not sufficient.
