Decoder Installation - Märklin 60947 Bedienungsanleitung

Decoder Installation

The locomotive must be checked before installing the de-
coder to make sure that it (locomotive) is in good mechanical
and electrical condition. There are situations when the loco-
motive will have to be repaired before installing the decoder.
First unsolder the wires to the current pickups (pickup
shoe(s)), motor, and the lights. After that remove the old de-
coder or reverse unit. Screw down the circuit board retainer
and solder the wires to the motor connections, pickup(s),
and any functions.
The colors for the wires correspond to the Märklin Stan-
dard; see Page 28 for a comparison table for NEM. Position
the new decoder and solder the wires according to the
diagram nearby.
If the lights are grounded to the locomotive's or powered rail
car's ground on the frame, we recommend that the lights
be insulated from the locomotive ground. To do this, use the
E604180 plug-in bulb holder(s) and E610080 light bulb(s). This
will give you flicker-free lighting.
If your locomotive or powered rail car is equipped with LED
lighting, then series resistors must absolutely be installed.
Series resistors differ according to the current the design.
Find out the correct values for your LEDs. You may have to
ask your specialty dealer about this.
If you want to retrofit your locomotive or powered rail car
with LEDs, the cathodes (-) on the LED are connected to the
light output on the decoder. Don't forget series resistors!
The anodes (+) are connected to the common wire (orange).
The common ground return (orange) must not be connected
to the ground for the locomotive or powered rail car.
Position the speakers, fasten it with the adhesive pad and
put the cable into the connector on the circuit board.
This procedure is identical for the 60945, 60946 and 60947
decoder. Make sure that you pay absolute attention to the
notes for the colors of the wires for each decoder.

If the lighting is grounded to the locomotive or powered
rail car's frame, this may cause flickering. If you don't want
this, then the lighting must be insulated. We recommend
replacing the light bulb(s) with the 604180 plug-in socket(s)
and the 610080 light bulb(s). The ground is then connected to
the orange wire.
