Introduction:
You have purchased the 4 fold switch decoder kit SA-DEC-4 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 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.
