Assembly Instruction
s88-Clock Master
from the Digital-Professional-Series !
s88-ClockMaster-B
To be used as timing generator for the s88-
feedback bus to operate the switch board light
decoder GBS-DEC-s88 without the connection to a
digital control unit or to a PC with model railway
software.
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).
• These high quality kits are easy to assemble.
• Model railway kits are not only well come handicraft jobs but
they can be purchased with a considerable price reduction.
This will justify to spend about an hour because you do not
need more time to assemble those kits.
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 diode please keep special attention the correct polarity
(marked line for the cathode).
Light emitting-diodes have to be assembled that way that the
longer leg has to be inserted to the pc-board marked "+".
Before assemble please push the distance spacer onto the
legs.
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 of the capacitor is in
correspondence with the marking on the pc-board.
It has to be attended to the flattened side of the Sensor MC3....
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 correct socket assuring that the
notch or the printed point is corresponding to the half-rounded
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.
