12. Troubleshooting for digital operation
The ZIMO sound decoder used in this locomotive is extremely robust and
includes thermal cut-outs and overload protection on all outputs. However
they are not immune to damage, so please avoid making changes or re-wiring
unless you are confident or experienced. For the novice, there are some things
which may appear to be a fault but which can be remedied after a few checks.
Please refer, in the first instance, to the table on the next page.
Resetting the decoder
With so many CVs, which may be changed to customise your model, it is possible
that undesired results might inadvertently occur, or the sounds behave oddly. It is
normally simple to undo these programming errors but sometimes, especially if you
have made multiple CV changes, it is more difficult. Use CV8 = 8 to reset the entire
project back to how it was supplied by us. This will preserve all the sounds held
onboard. Any CV changes you have subsequently made will be lost. This includes
loco address or ID, which will be reset to 3, and any changes to global or individual
sound levels.
Changing CVs
The precise sequence of keystrokes will depend upon your DCC controller, but there
are two types of what is commonly called ‘CV programming’.
Service mode programming requires the use of a dedicated section of track
occupied by one loco at a time. As this does not require the loco ID to be entered, it
is the usual method used to set the address. Switching to this mode usually ‘cycles’
the power to the loco automatically.
Programming on the main or POM is exactly as the name suggests. It requires
entry of the locomotive address to avoid accidentally reprogramming all the locos
on the layout. It does not interfere with normal running of the layout so can be
used to make changes ‘in real time’. However, it does not cut or ‘cycle’ power to the
reprogrammed loco.
Both of these methods have their advantages, but some CV changes are only
‘saved’ or put into action when the decoder ‘reboots’. This requires the power to be
cycled (switched off and on). If you use POM exclusively, please be aware that for
some DCC controllers and some CV changes to be effected, you will need to cut the
power to the decoder. Usually tilting the loco to one side, so it breaks contact with
the rails for a few seconds, will suffice.
