English Multi-Timer 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. ni Electrical hazards k Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. ta m el ek Never perform wiring on a powered module. Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity.
Multi-Timer English Fire risk ni Thermal danger k 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.
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 ta m el ek 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.
Multi-Timer k ni ta m tro el ek 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.

Operation overview Four outputs Four modes of operation 1. time switch 2. pulse delay 3. random switch el ek When used in analogue layouts: tro When used in analogue or digital layouts: ni k 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. 4.
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. el ek tro ni k 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.
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. Application el ek tro ni k 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.
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 tro ni k 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.
English Multi-Timer 4.4. Operation mode 4 "Start-Brake-Stopover Switch" Use in analogue layouts only The Multitimer controls ni 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.
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.

Multi-Timer English ni k Example 2: Signal set to "Clear" (switching input 1 open) ta m s el ek tro 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.

Multi-Timer English Ceramic capacitors k 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. ni Electrolytic capacitors el ek tro Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized.
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. Integrated circuits (ICs) tro ni k 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.

English Multi-Timer 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.). k 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.
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.: ta m s el ek tro ni k 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.
