Littfinski DatenTechnik 050061 Light Power Module
Introduction:
You have purchased a kit for your model railway that is supplied within the assortment of Littfinski DatenTechnik (LDT).
- These kits are easy to assemble and they are a product of high quality.
- Model railway kits are not only welcome handicraft jobs but they can be purchased with a considerable price reduction.
This will justify to spend about an hour because you do not need more time to assemble those kits.
We are wishing you having a good time using this product.
General:
Tools required for the assembly
Please assure that the following tools are available:
- a small side cutter
- a mini soldering iron with a small tip
- solder tin (if possible 0.5mm diameter)
Safety Instructions
- We designed our devices for indoor use only.
- All electrical and electronic components included in this kit shall be used on low voltage only by using a tested and approved voltage transducer (transformer). All components are sensitive to heat. During soldering the heat shall be applied for a very short period only.
- The soldering iron develops up to 400°C. Please keep continual attention to this tool. Keep sufficient distance to combustible material. Use a heat resistant pad for this work.
- This kit consists of small parts, which can be possibly swallowed from children. Children (especially under 3 years) should not participate on the assembly without supervision.
Set-Up:
For the board-assembly please follow exact the sequence of the below assembly
list. Cross each line off as done after completing the insertion and the
soldering of the respective part.
For the diode please keep special attention to the correct polarity (marked
line for the cathode).
Attend to the connection marked “+” at the tantalum capacitor. This mark has
to correspond to the mark on the pc board. Resistor networks are marked for
assembly with a printed circle or a square at one end. Insert this component
that way that the marking correspond with the first and second bore of the pc
board. The first bore has been additionally marked at the pc board with a “1”.
You can identify the 1kOhm network by the printed mark of 102 and the 100kOhm
network by the printed mark 104.
Please assemble the clamps to blocks of 15 and 21 connections.
The transistors have to be assembled in that direction that the metal side
will face to the bold white line on the pc-board.
Integrated circuits (ICs) are either marked with a half round notch on one end or a printed point for the correct mounting position. Push the ICs
into the correct socket assuring that the notch or the printed point is
corresponding to the half-rounded marking on the pc-board.
Please attend to the sensitivity of the ICs to electrostatic discharge which
will cause immediate damage of the IC. Before touching those components please
discharge yourself by contacting an earthed metal (for example: an earthed
radiator) or work with an electrostatic safety pad.
Cut out the labels for the sockets BU2 and BU3 and stick them onto the RJ-45 sockets. This will indicate an explicit identification for the connection of light power module via patch cable.

Soldering instruction
Provided you have no special experience in soldering electronic components please read first this soldering instruction before starting the job. Soldering has to be trained!
- Never use additional fluxes for soldering electronic circuits which contain acids (e.g. zinc chloride or ammonium chloride). Those can destroy components and printed circuits when not washed off completely.
- As soldering material only lead free soldering tin with a rosin core for fluxing should be used.
- Use a small soldering iron with max 30 Watt heating power. The solder tip shall be free from scale to assure an excellent heat transfer to the area to be soldered.
- The soldering shall be performed on a speedy way because a long heat transfer can destroy the components. To much or to long heating can take off the copper pads and copper tracks from the board.
- For a good soldering a well tinned solder-tip has to be brought in contact to the copper-pad and the component wire at the same time. Simultaneous a little solder-tin shall be applied for heating up. As soon as the solder-tin starts melting the tin wire has to be taken away. Just wait until the tin has well wetted the pad and the wire and take the soldering iron away from the soldering area.
- Make sure not to move the just soldered component for about 5 seconds after removing the soldering iron. This should create a silver shining faultless soldering joint.
- For a faultless soldering joint and well done soldering is a clean non oxidized soldering-tip absolutely required. It is not possible to perform a sufficient soldering joint with a dirty soldering tip. Therefore please clean the soldering tip from excessive solder-tin and dirt by using a wet sponge or a silicone cleaning pad after each soldering process.
- After completion of the soldering all connection wires have to be cutted off directly above the soldering joint by using a side cutter.\
- By soldering semiconductors (transistors, diodes), LED
s and ICs is it very important never to exceed the soldering time of 5 seconds to prevent the destruction of the component. It is absolutely required to attend to the correct polarity of the component before starting the soldering process. - After the board assembly carefully control the pc-board about correct insertion of the components and the correct polarity. Please check if no connections or copper tracks are accidentally short circuited by soldering tin. This can not only result to malfunction of the module but also result to a destruction of expensive components.
- Please take into account that improper soldering joints, wrong connections, faulty operation or wrong board assembly is not a matter within our sphere of influence.
General installation information
The contact-wires of resistors and diodes to be assembled in a lying position shall be bended in accordance to the raster distance into a right angular position and assembled into the specified bores (in accordance to the board assembly plan or the assembly markings). To prevent that the components will not fall out by turn-over the pc-board please bend the connection wires about 45° apart and solder them carefully to the copper pads on the rear side of the board. Finally the excessive wires shall be cutted off with a small side cutter.
The resistors in the supplied kits are metal-foil resistors. Those have a tolerance of 1% and are marked with a brown “tolerance-ring”. The tolerance ring can be identified by the larger margin distance respectively the larger distance to the other four marking rings. Normally there are five color rings on the metal-foil resistors. To read the color code you have to locate the resistor that way that the brown tolerance ring will be on the right side. The color rings will be red now from left to right!
Please take care to assemble diodes with the correct polarity (position of the cathode marking). Take care about a very short soldering time! The same will apply to the transistors and the integrated circuits (IC`s). The flat side of the transistors has to correspond with the marking on the pc-board.
The transistor legs should never be assembled in a crossed position.
Further those components should have a distance of about 5mm to the board.
Attend to the short soldering time to prevent the damage of the component by
excessive heat.
Capacitors shall be assembled into the respective marked bores, the wires to be bent a little apart and careful soldered to the copper pad. By the assembly of electrolytic capacitors (electrolytic cap) it has to be attended to the correct polarity (+,-)! Wrong-way soldered electrolytic capacitors can explode during the application! Therefore is it very important to check the correct polarity two- or even better three-times. In addition it has to be attended to the correct capacitor values, e.g. n10 = 100pF (not 10nF!).
A careful and clean assembly will drastically reduce the possibility that anything will not be in correct function. Check every step and every soldering joint two times before carrying on! Attend closely to the assembly list! Perform the described step not different and do not skip any step! Mark each step as done at the foreseen column after assembly and careful check.
Take your time. Private work is no piece-work because the time for careful assembly work is much less than an extensive fault diagnosis.
Final assembly
Sockets and integrated circuits (IC´s) of the kits will be supplied on a piece
of foam to assure safe transport.
This foam shall never be used below or between components as this foam is
electrical conductive.
In case the kit will be taken into operation the conductive foam can produce a short circuitry and destroy the complete kit. Anyhow the function of the module will not be as expected.
