Hornby R8249 Mode D'emploi

R8249 Hornby Locomotive Decoder
The Hornby locomotive decoders may be used with all
standard digital control equipment that conforms to the
NMRA standards.
For confirmation please contact your system supplier.
Note the normal running current carrying capacity of
the Hornby Decoder is 500mA peaking at 1Amp shared
with the Function outputs. If this capacity is exceeded
the decoder will cut out.The decoder must not touch
any metal parts of the locomotive as this may cause a
direct short and permanently damage the decoder.
Do not wrap the decoder in insulating tape as the
decoder requires a cooling smooth air flow across it's
surface. If air is restricted the decoder may over heat
and be damaged. As a precaution it is advised that any
exposed metal surfaces that the decoder may come into
contact with are covered with insulating tape, especially
on the surface where the decoder is to be installed.
If there is no decoder housing for the decoder to be
located into, the decoder can be fixed in position using
double sided tape or pads.
Decoder equipped locomotives must not be operated
using an overhead power supply or catenary system.
Before installing the Hornby Decoder make sure that
the model runs efficiently in DC mode.
A poorly running locomotive will not be improved by
adding a decoder!
The R8249 Hornby Decoder is fitted with an NEM652 / NMRA plug. To install the Hornby decoder, remove
the locomotive body as per the manufacturer's instructions and locate the decoder socket. Remove the
"plug" from the socket and ensuring that Pin 1 of the decoder is aligned with Socket 1 (orange wire) of the
plug and then insert. Do not force the plug into the socket as this may damage the pins. If the locomotive
incorporates lights and the decoder is inserted the opposite way round the lights will not work!
Programming the R8249 Hornby Decoder
To programme the decoder consult your digital system handbook.
The locomotive address, acceleration and deceleration plus other features of the Hornby Decoder can be
altered as many times as you wish by the standard reprogramming procedure. All the features are "stored"
permanently on locations "in" the decoder even when the power is switched off to the locomotive and track.
The locations are known as Configuration Variables or "CVs". The CVs can only be altered once the
locomotive is placed on a "live" track or a "Programming Track". The Hornby Decoder is factory set as
"No.3" with a speed step setting of 128.The Hornby Decoder may be used immediately after installation
but it is recommended that the locomotive should have it's operational functions tested on a Programming
Track before the locomotive's body is refitted to the model.
If you require more information please contact Hornby or your local stockist.

Important Note:
The locomotive must be removed from the track
before installing or removing a locomotive
decoder.
To prevent the risk of electro-static damage
occurring to the decoder, NEVER directly touch
the component parts of a decoder PCB.
