User manual

Introduction:
You have purchased the Basic-Module for the layout light control Light-DEC-
Basis as a kit for your model railway supplied within the assortment of Littfinski
DatenTechnik (LDT). These kits are of high quality and 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 (attend as well to the rear side of this assembly instruction).
• 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 450°C. Please keep continual attention to
this tool. Keep sufficient distance to combustible material. Use a heat resistant pad
for this work.
• This kit contains 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 above 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 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.
