When reading or programming, very small currents usually flow, which do not damage the decoder in the 
event of a short circuit.

Connection of special functions

 

 

An additional special function such as smoke generator, automatic coupling or a cab lighting can be 
connected to the special function output A1 (green).

 

 

Connection of incandescent lamps

 

 

To adjust the operating voltage and to avoid very high inrush currents, we recommend a resistance of 68 
ohms to the incandescent lamps in series.

 

 

 

Connection of energy storage device 71800

ATTENTION:

 Soldering on the decoder should only be carried out by experienced professionals with the appropriate 

tools. For decoders that have been damaged by improper handling, the warranty claim is void.

 

  

A short circuit in the area of motor, lighting and power consumption

 

 

destroys the building block and possibly the electronics of the locomotive!
