Introduction:

You have purchased the 4-fold decoder kit 1-DEC-DC for your

model railway supplied within the assortment of Littfinski

DatenTechnik (LDT). The 1-DEC-DC kit is a high quality

product which is easy to assemble.

We wish you having a good time to assemble and using this

product.

The 4-fold decoder 1-DEC-DC of the Digital-Professional-

Series can be used without any problems on your digital

railway.

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

• 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 a heat 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 consist of small parts which can possibly be

swallowed from children. Children (especially under 3 years)

shall 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 diodes please keep special attention to the correct

polarity (marked line for the cathode).

With reason to different makes of electrolytic capacitors you

will find different markings of the polarity. Some are marked with

"+" and some are marked with "-". Each capacitor has to be

assembled to the board that the marking on the capacitor is in

correspondence with the marking 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 socket assuring that the notch or

the point is corresponding with the triangular marking on the pc-

board.

Please attend to the sensitivity of the IC´s 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.

Please attend to the mark "+" of the rectifiers. Some

manufacturers mark the "+" connections additionally with a

longer connection wire. If the rectifier shows as marking a

flattened side this side has to correspond with the marking on

the pc-board.

For sufficient heat transfer the diodes D20 and D21 should not

be assembled directly to the pc-board but shall be soldered at a

distance of 5mm to the board.

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! 1. 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. 2. As soldering material only lead free soldering tin with a rosin core for fluxing should be used. 3.

Remarks: The decoder addresses for magnetic accessories are combined in groups of four. The addresses 1 to 4 build the first group. The addresses 5 to 8 build the second group etc. Each 1-DEC-DC decoder can be assigned to any of these groups. Which turnout of a group will be activated for the addressing does not matter. • If the decoder has recognized the assignment correctly the connected turnout will move a little faster. Afterwards the movement slows down to the initial 1,5 seconds again.
