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:
Page 5

tams elektronik
nglish Multi-Timer
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.

angerous 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 of 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.
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.
Page 8

tams elektronik
Multi-Timer nglish
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
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 nglish
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. xample:
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 or each output.
The maximum activating time is 30 seconds.
Each change in state at one o 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 o the contacts o the switching input. A maximum
o 64 changes in state can be saved within the set time o delay. In
case there are more changes o state within the time o delay, the
changes o state irst executed will be deleted.
Application
You can apply the operation mode 2 or all actions that should be
executed with a time delay a ter a preceding occurance, e.g. opening
the level-crossing a ter a train has passed or setting the signal to stop
a ter a train has passed.
The operation mode 2 can be used as well to release switching
operations delayed, in order to prevent switching contacts rom being
blocked permanently. Example: The power supply in a rail section has
to be switched o (and the train brought to a stopp), as soon as the
train has passed a reed contact. In case the train would stop
immediately a ter 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 nglish
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

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.

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

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

Multi-Timer nglish
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. very 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.
