6. Checklist for troubleshooting and error correction
Warning:
If you notice a strong heat development or if the decoder starts to smoke, disconnect the
connection to the supply voltage immediately.
Fire hazard!
Possible causes:
Possible cause: one or more connections are soldered incorrectly.
à
Check the
connections.
Possible cause: Short circuit between the decoder or accessories connected to the retrun
conductor for all functions and metal parts of the locomotive or the rails.
à
Check the
connections. A short circuit can result in irreparable damage.
6.1. Problems with programming the decoder
The CV values cannot be changed.
Possible cause:
Different values are entered in CV 15 and CV 16 (decoder lock).
à
Enter the same value in
CV 15 as in CV 16.
6.2. Problems in driving mode
After installation of the decoder the loco runs badly or not at all.
Possible cause:
The current consumption of the loco (and thus the transmission of the digital signals to the
decoder) is insufficient.
à
Check the current collectors / the slider and if necessary ensure
a better current consumption.
The locomotive stops and the lights that are switched with F0 flash.
Cause: The overload protection has been activated because the current consumption is higher
than the maximum total current of the decoder or there is a short circuit at the motor output.
à
Eliminate the cause of the overload. Check the following points in particular:
Current consumption of the motor and the additional consumers. If the current
consumption is higher than the permissible current, the decoder is not suitable for this
locomotive.
Smooth running of all moving parts (e.g. wheels, rods).
Condition of the brushes
Note: The decoder must first be de-energised before it will respond to run commands again.
In digital mode, the locomotive suddenly runs at high speed.
Possible cause:
Interference signals from the layout have switched the decoder to analogue operation.
à
As it is often not possible to localise the cause of the interference signals, it is advisable
to switch off the automatic analogue detection during digital operation.
