4-fold switch decoder

from the Digital-Professional-Series !

SA-DEC-4-DC-B Part-No.: 210211

>> kit <<

Compatible to the DCC-Format:

(e.g. Lenz Digital Plus, Arnold-, Märklin-Digital=, Intellibox,

TWIN-CENTER, Roco-Digital, EasyControl, ECoS,

KeyCom-DC, Digitrax, DiCoStation, Zimo and others.)

For the digital control of:

⇒ consumers of up to 4 Ampere on each output

(e.g. illumination, switching track sections voltage free).

⇒ jammed turnout- and signal drives

(drives with integrated end switch).

This product is not a toy! Not suitable for children under 14 years of age!

The kit contains small parts, which should be kept away from children under 3!

Improper use will imply danger of injuring due to sharp edges and tips! Please

store this instruction carefully.

Introduction:

You have purchased a kit for your model railway supplied within

the assortment of Littfinski DatenTechnik (LDT).

The SA-DEC-4 kit is a high quality product which is easy to

assemble.

We are wishing you having a good time for assembling and

application of 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

• 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 and zener diodes please keep special attention

to the correct polarity (marked line for the cathode).The zener

diode D4 has a thicker connection wire and is suitable for

position D4 only.

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 (IC`s) are either marked with a half round

notch on one end or a printed point for the correct mounting

position. Push the IC`s 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.

The relays are marked with a thick line on one side. This line

has to correspond to the marking on the pc-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.

Littfinski DatenTechnik (LDT) Operating Instruction 4-fold switch decoder from the Digital-Professional-Series ! SA-DEC-4-DC-F Part-No.: 210212 The DCC-Digital-Systems uses different color codes respectively indications for the two digital cables. Those markings are indicated next to the clamp KL2. These markings have not necessarily to be maintained correct as the decoder converts the signal automatically to be correct. The decoder receives the power supply via clamp KL1.

• If you press the first key of the programmed group of keys or you send a switch signal for this address from a PC the addressed bistable relay should now switch the connected consumer on or off. Switching consumers via loc-addresses (e.g. Lokmaus 2® or R3®): The decoder SA-DEC-4-DC makes it possible to switch consumer via loc-addresses. For example switching with the functional keys F1 to F4 of the Lokmaus 2® or R3®.
