Locomotive decoders of the series 30 plus English
10. Check list for troubleshooting
 Parts are getting very hot and/or start to smoke.
Disconnect the system from the mains immediately!
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 return 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.
Problems with the driving characteristics
 After programming the decoder the locomotive does not run or runs
badly.
Possible cause: The set values for the CV are inconsistent.
à Perform a decoder reset and program the decoder anew.
 In digital mode the locomotive suddenly runs very fast.
Possible cause: Interfering signals from the layout have switched the
decoder to analogue mode. à As the origin of the interfering signals´
often cannot be found, it is advisable to switch off the automatic
recognition of the analogue mode during digital operation. As an
alternative you can increase the value for CV#11.
 The CV values cannot be read out by RailCom.
Possible cause: RailCom is switched off. à Alter the value of CV#29
(add "8" to the input value).
 The decoder switches off in operation, switches on after a short time
and switches off again immediately.
Possible cause: The overload protection was activated, as the current
consumption exceeds the decoder´s maximum total current. à Check
the current consumption of the motor and the accessories. Possibly the
decoder is not suitable for being mounted in this locomotive.
