Introduction:
You have purchased the 8-fold track occupancy detector GBM-8
for your model railway layout. The GBM-8 is a high quality
product that is supplied within the
Littfinski DatenTechnik (LDT).
We wish you having a good time using this product.
The track occupancy detector GBM-8 of the
Professional-Series can be easily operated on your digital model
railway.
The GBM-8 is suitable for the direct connection to the feedback
modules RM-88-N-O / RM-DEC-88-O and Roco 10787.
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 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 please keep special attention to the correct
polarity (marked line for the cathode).
Resistor-networks are marked on one end with a printed circle
or a square. Assemble this component that way that the marking
corresponds with the marking between the first and second bore
respectively with the marking "1" on the pc-board.
The 330Ohm networks (RN1 and RN2) contain the label "331"
for identification of the resistance value. The 10kOhm networks
(RN3 and RN4) contain the label "103".
Please attend to the flat side of the transistors.
Please put the 2-pole clamps and the 3-pole clamps together
to a block with 10 respectively 12 connections before assembling
the clamps to the board.
