Change turnout by reversing polarity of DC voltage. Use
SPDT switch & DCCconcepts PSU-2, DC supply plus DPDT
switches. DCCconcepts switch packs are economical
and include both switches and a panel LED selection.
Use with DCCconcepts ADfx-2 or ADfx8 decoders. as
these also have excellent added features and are excel-
lent value If using other brands pre-check they can de-
liver 20mA during the change cycle. (even though 20ma
is very low current some cannot)
Cobalt Classic WLife-time Warranty
DCCconcepts’ guarantees and warranties are always made in respect of the
original owner of the products. While our rst priority is to always be sure that
users of our products are given the best possible service we do also reserve the
right to request proof of purchase so we can properly establish that you were
the original purchaser and user of the product.
DCCconcepts use the best quality materials, thoroughly testing each and every
Cobalt Classic Wmotor multiple times prior to packaging them for sale and
so we have no hesitation in providing you with the best warranty possible.
Simple promises only need simple words:
If your Cobalt Classic Wever fails or needs service when being used un-
der fair and reasonable conditions we will repair/replace it at no charge.
We offer this guarantee for as long as you own it.
Installing the Cobalt Classic Wturnout motor
First, assemble your Cobalt Classic Wturnout motor: The
throw arm is already pre-centred to make this easy for you.
(1) Insert the fulcrum bar into the slides (The horizontal part of the bracket with the
holes can be either at the top or bottom . We usually have it at the bottom).
(2) Now add the throw wire, passing the straight end upwards through the centre
hole of the adjustable fulcrum bar and then inserting the bent end of the
wire into the smaller top hole on the end of the throw arm.
Secure the throw wire in place with the washer head screw provided.
(3) Add the pre-cut self adhesive foam pad to the top of your Cobalt
Classic Wmotor (leave the protective top on the pad until installation)
Now we are ready for the installation.
As well as the pre-cut foam pad, we include mounting screws with every
Cobalt Classic W turnout motor so all you will need are basic tools.
You will need a screwdriver and a drill, plus both 1.5mm (for screw pilot
holes) and 10mm drills for the throw-wire installation. (The exact drill
sizing you use is not critical so close or imperial sized drills will be OK). If
the baseboard is over 20mm/0.75” thick, increase the larger drill size.
(1) Mark the position of the hole in the turnout tie-bar with the turnout
blades held at their mid-way position. This hole may be at the centre or at
the end of the tie-bar.
(2) Make a pilot hole at that mark, then drill right through the baseboard
using the larger drill bit. Be sure to keep the drill vertical as you drill.
(It is also good practice to use a countersink bit to clean up the hole top
and bottom a little after drilling)
(3) Remove the top protective layer from the self adhesive pad and from
below the baseboard, insert the throw wire into the hole in the tie bar.
When you are sure that your Cobalt Classic Wis centralised relative
to the hole, and aligned properly along the turnouts axis, press it into
position on your baseboard. (it can face either way). Test operation.
(4) Adjust the fulcrum bar as needed by raising or lowering it. Lowering it
increases throw & blade pressure. Raising it reduces throw & pressure.
(5) When happy with operation, add a small drop of PVA to the case
where it meets the fulcrum bar to hold it in position.
(6) Use screws provided to screw Cobalt Classic Wpermanently in position.
Owners Manual
Cobalt Classic W
The DCCconcepts Cobalt Classic W (Omega) is the most
powerful and most reliable turnout motor in its class and it is
able to be used with all scales, from the diminutive T scale,
through to Z, N, TT, HO, OO, EM, P4, S, O & G.
Cobalt Classic W is easy to install, quiet and very reliable.
It has three inbuilt SPDT switches - One is directly “Diode
linked” to the drive power inputs for computer IO (feedback)
or other low power applications. The other two SPDT switch-
es are fully independent with higher power handling for frog
power control or any other switching needs you may have.
This makes DCCconcepts Cobalt the most versatile point
motor available... and the answer to all layout wiring needs!.
Cobalt Classic W is powered by low voltage DC and it is
changed by reversing the polarity of the DC power.
We recommend that you use a regulated DC power supply
between 9 and 12v DC, however we do understand that
some systems for larger scales have higher accessory
voltage power supplies and that DCC accessory decoders
may have higher output voltages, so we’ve added a simple
“voltage range change”switch to the Cobalt Classic W. This
allows it to accept two power input ranges, 6~12v or 12~18v.
Please read all of this manual before you install your Cobalt
Classic W. It contains all the detailed information you’ll need
for installation and wiring. More manuals and “how to” videos
that add even more detail will be available on our Website.

Wiring your Cobalt Classic Wturnout motor
Important: Cobalt Classic Whas a different range of
connections to the original “Cobalt Analog” motor
There are 9 spring terminals on Cobalt iP W. The terminals
will accept a wide range of wire sizes. Use the heaviest
convenient wire size. The wire should be stripped carefully
exposing appx 10mm of bare wire. The best method is to
“ring-strip” the insulation and then twist it as it is removed,
This ensures that there are no free copper strands.
Note: The wire will always be more secure if it is NOT tinned
This drawing shows the label that is applied to each
Cobalt Classic W. turnout motor. Wiring information is also
repeated on the bottom of the PCB to ensure it’s never lost.

Cobalt Classic Whas a “Voltage Range Switch” on the PCB, This gives a
choice of 6~12 or 12~18v DC & all you need to do is change the switch so
that it matches your Power supply voltage or Accessory decoder output.
