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
tantalum capacitors
please keep special attention to the
connection marked "+". This has to correspond to the mark on
the pc-board.
Resistor networks
are marked at the one side with a printed
circle or a square. Please insert the part that way that the marking
of the part corresponds with the marking on the pc-board
between the first and second bore. Additional marking at the first
bore is a "1" on the board.
The
rotary code switch
is either marked on one side with a
printed dot or a tapered side for the correct mounting position.
Assemble this part that the marking corresponds to the tapered
marking on the 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 correct socket assuring that the
notch or the printed point is corresponding to the half-rounded
mark 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
glue the tree
labels
onto the
RJ-45 sockets
for
identification of the output socket
BU1
(cable in direction to the
command station) and the two input sockets
BU2
and
BU3
(cable
from next feedback unit) for the
left
and
right
s88-bus line
