Proto-Coupler Installation
Owners of 2-rail models who intend to run this locomotive on a 3-rail layout may wish
to use the M.T.H. Proto-Coupler so that they may enjoy the remote uncoupling
anywhere on the layout.
A Proto-Coupler and the necessary mounting hardware are included in the packaging
with each 2-rail locomotive. The wire harness in the tender is prewired with a plug-in
connection for the Proto-Coupler.
To install the Proto-Coupler on a 2-rail tender, follow the step by step instruction listed
below.
- First remove the Fine Scale European Coupler and pilot beam from the bottom of
the tender chassis.
- Install the optional pilot beam with no coupler installed
- Next remove the shell from the tender by removing the 4 body screws and then
unplug the wire harness between the shell and the chassis.
- Attach the proto-coupler to rear tender truck as shown.
- Plug the Proto-Coupler to the black connector provided.
- Reconnect the wire harness between the tender chassis and the tender shell.
- Reattach the tender shell. Remember that the front step piece goes under the chassis.
When power is applied to the engine the Proto-Coupler can be operated anywhere on
the layout. To operate the coupler in the command mode, press the rear coupler button
on the DCS remote each time you want the coupler to open.
To operate the coupler in the conventional mode, the coupler can be opened by quickly
pressing the Bell Button and Horn Button (1 Bell and 3 Horns) on a Z-4000 or
compatible Toy Train Transformer. Refer to the Proto-Sound 3.0 Operating
Instructions on page 11.
