C19's - sound systems

[peterbunce]

Hi,

The new C19 - can I fit a voltage sensing sound system - I am in England where they use the voltage sensing system to regulate the chuff's?

What do you mean by "voltage sensing?" If you mean a sound board that bases the chuff rate on the motor voltage, then the PC board in the tender has solder pads which you can use to feed the motor voltage to the sound board.

If we wish to use the optical contacts in the cylinders, can leads from the sound board be attached to the PC board in the tender without additional electronics.
  Thanks you.

No additional electronics are needed to connect sound systems to the C-19.  In most case a single wire connection between the sound board chuff input to the C-19s chuff output.  In a few cases the sound boards chuff ground may also have to be connected to the C-19 ground.

Hope that helps.

Stan, which solder tab on the board would that be? I've noticed with the Revolution installed, you've got to jumper the B+ and ground to the rail (battery) inputs to send voltage forward to the locomotive for lights, etc. I would presume the optical chuff sensors to also need this power feed.

All of the Bachmann locomotives that have the expanded socket need for power to come through the socket.  This power is used to power the fans, the lighting, the smoke, and the chuff.

Most devices that plug into the socket (including the dummy board that comes with the locomotive) have a rectifier built in.  This rectifier powers these locomotive devices.

Unfortunately I do not believe the Aristocraft unit has this rectifier built in and therefore requires the locomotive's + and -to be separately powered either through the battery or through a user installed rectifier.  All other devices in the market that plug into the socket have the needed rectifier built in.

Once you have power to the locomotive the chuff sensors will work and you simply hook up the chuff output on the side of the board labeled "chuff sensor" to the chuff input on the sound board.

Hope that helps.
