6.1 Installation
The installation of the circuit boards depends individually on the
model and the equipment. The main board has the same dimen-
sions as our standard circuit board or decoder. Thus the available
space can be used. Usually the existing main board is replaced with
the new R/C board. A suitable place must be found for the switch
circuit board. It is important that the solder joints of the printed
circuit boards are not in contact with metal parts in the locomotive,
otherwise short circuits will result.
ATTENTION! If the system is used with permanent track voltage,
the switch PCB must be properly mounted on a metal weight. On
the one hand to cool the rectifier and on the other hand to protect
it from damage by hot parts. However, make sure that the solder
joints are properly insulated!
The experienced modeler will integrate the R/C circuit board to the
analog sound or sound decoder. The existing supply lines must
be separated and extended accordingly. The following illustrations
show the possibilities.
Attention! These steps should only be carried out by experien-
ced model railroaders.
