3. Safe and correct soldering

ta
m


el
ek


Use a small soldering iron with max. 30 Watt or a regulated
soldering iron.
Only use electronic tin solder with flux.
When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
Insert the component connecting pins into the PCB´s holes as far as
possible without force. The components should be close to the
PCB`s surface.
Observe correct polarity orientation of the parts before soldering.
Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or soldering
eyes.
Apply the soldering tip to the soldering spot in such a way that the
part and the soldering eye are heated at the same time.
Simultaneously add solder (not too much). As soon as the solder
becomes liquid take it away. Hold the soldering tip at the spot for a
few seconds so that the solder flows into the joint, then remove the
soldering iron.
s

tro
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions.


Do not move the component for about 5 seconds after soldering.
To make a good soldering joint you must use a clean and unoxidised
soldering tip. Clean the soldering tip with a damp piece of cloth, a
damp sponge or a piece of silicon cloth.
Cut the wires after soldering directly above the soldering joint with a
side cutter.
After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created by
accident. This would cause faulty operation or, in the worst case,
damage. You can remove excess solder by putting a clean soldering
tip on the spot. The solder will become liquid again and flow from
the soldering spot to the soldering tip.

4. Operation overview
ni
k
Most locomotive decoders with load control are designed to control
locomotives with direct current (d.c.) motor. There are only few
locomotive decoders with load control available to control locomotives
with alternating current (a.c.) motor. In order to drive a locomotive
with a.c. motor in digital operation with load control, it is widespread to
alter the motor (by replacing the field coil with a permanent magnet or
exchanging it completely).

5. Technical specifications
tro
The load control adapter LRA has to be mounted between the a.c.
locomotive motor and a decoder with load control for d.c. motors. It
allows to drive a.c. motors with locomotive decoders for d.c. motors
and supplies the load control, without altering the motor.

Preparation
Put the sorted components in front of you on your workbench.
ni
k
The separate electronic components have the following special features
you should take into account in assembling:
Electrolytic capacitors
tro
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. The
value is given on the package.
Diodes
el
ek
Electrolytic capacitors are available with different voltage
sustaining capabilities. Using an electrolytic capacitor with
a voltage sustaining capability higher than required is
always possible.
ta
m
s
Diodes allow the current to pass through in one direction
only (forward direction), simultaneously the voltage is
reduced by 0,3 to 0,8 V. Exceeding of the limit voltage
always will destroy the diode, and allow current to flow in
the reverse direction. The diode type is printed on the
package.

The negative end of the diodes is marked with
a ring. This is shown in the PCB layout.
Observe the polarity! One of the two leads
(the shorter one) is marked with a minus sign.
Depending on the space available in the
locomotive you should mount the capacitors
either
 upright, with the package vertical to the
PCB or
 horizontal, with the package in parallel to
the PCB. Bend the legs before soldering
near to the package to 90 degrees.

7. Connecting the LRA
Preparation
tro
ni
k
Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
 Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
 Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.
el
ek
With a ready-built module you can carefully erect the capacitors
mounted horizontally, as needed with regard to the space available in
the locomotive.
! Be especially careful not to apply pressure to the soldering pads
and not to damage the PCB tracks.
s
Connection to locomotive motor and locomotive decoder
ta
m
Connect the LRA, according to the following list, to the locomotive
motor and the motor output of the locomotive decoder. Solder the
connecting cables directly to the connecting points of the PCB, in order
to save space. When there is enough space available in the locomotive
you can alternatively connect the cables via pin strips and sockets
(spacing 2,54 mm, not included in the package).

Advice: Possibly the locomotive´s driving direction does not match the
direction set at the control unit after mounting the load control adapter.
In this case you should exchange the connections X1 and X2 or X5 and
X6 or program the decoder´s CVs that way, the driving direction is
inverted.
Fix the LRA with a screw or double sided adhesive tape, in order to
prevent components from touching accidentally metal parts of the
locomotive.
ta
m
s
! Caution: When components of the LRA touch the metal parts of
the locomotive, there is a risk of short circuits. The LRA as well as the
connected decoder possibly can then be damaged!
Optimising the driving characteristics
The standard settings of the load control parameters of locomotive
decoders regularly are optimised to control d.c. motors. For that reason
the driving characteristics of the locomotive possibly are not satisfying
after having mounted the LRA. In this case you have to alter the load
control parameters of the decoder according to the instructions in the
decoder´s manual. Proceed in small steps.
