Upgrading Multiple-Unit Diesels - DCS Proto-Sound 2.0 Diesel/Electric Locomotive Upgrade Kit Installation Manual

Upgrading Multiple-Unit Diesels

This kit is designed for single diesel or electric locomotives only. There
is no provision for wiring a coupler and/or back-up light into a dummy
or non-powered trailing unit. Similarly, the kit does not provide a way to
control powered trailing units. See the note below on four-motored
locomotives as serious damage can occur to the Proto-Sound 2.0
electronics if warnings are not heeded.
Four-Motored Locomotives
This kit is designed to upgrade only a single locomotive with one or two
motors. Engines with four motors in two separate body shells will
require two upgrade kits- and thus become two separate PS-2
locomotives that can be operated as a lash-up or as separate units.
Warning: Attempting to run three or four motors off of a single PS-2
board will damage the motor drive circuit and require board
replacement.
Lighting In Non-Powered Units
This kit does not provide connections for lights in non-powered
(dummy) units. Non-powered Proto-Sound One units with constant-
voltage lighting boards will work under DCS with no modifications. If
the non-powered trailing unit is equipped with lighting (ie: back-up light)
that is connected to the powered unit through a harness, you can use that
existing harness to connect those lights up to the PS-2 kit.
Proto-Couplers In Non-Powered Units
This kit does not provide connections for Proto-Coupleres in non-
powered (dummy) units, although it does include two PS-2 Proto-
Couplers.
Note: Original Proto-Sound Proto-Couplers will not work
consistently with the PS-2 board. The original Proto-Sound Proto-
Couplers require higher voltage to operate and therefore do not
open consistently when commanded with the PS-2 board.
came with a Proto-Coupler on the non-powered trailing unit, you can use
the existing harness to connect the newly installed Proto-Coupler on the
trailing unit.
