Introduction:
You have purchased the 4 fold turnout decoder kit
S-DEC-4-DC for your model railway supplied within the
assortment of Littfinski DatenTechnik (LDT). The S-DEC-4-DC
kit is a high quality product which is easy to assemble.
We are wishing you having a good time for assembling and
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
• 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 the zener diodes please keep special
attention to the correct polarity (marked line for the cathode).
The zener diode D4 has a thicker connection wire 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 (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 ICs to electrostatic
discharge which will cause immediate damage of the IC.
Before touching those components please discharge yourself
by contacting an earthed metal (e.g. 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 a flattened side as
marking this side has to correspond with the marking on the pc-
board.
