Decoder for Atlas N Scale H15/16-44 Locomotives 4
Atlas Model Railroad Co., Inc.
Silent Drive or Precision Glide Control
The H15/16-44 decoder provides an option to use either Silent Drive or
Precision Glide Control for motor control. Silent Drive is best for
coreless motors and for applications were you want absolutely silent
operation. Precision Glide Control provides much more precise slow
speed operation because it pulses the motor to ensure the friction of the
motor and drive train does not interfere with the operation. The default is
Precision Drive Control. The motor control selection is made using
CV50.
Preparing to Install the H15/16-44 Decoder
Before installing the H15/16-44 decoder in your locomotive, it is
necessary to test (and adjust, if necessary) the locomotive for proper
operation on conventional DC power. Replace any worn out parts, such
as brushes. Also clean any dirt or oxidation from the wheels and pickups
to insure that electrical contact is good. Now is also a good time to
lubricate your locomotive. A locomotive that runs well under
conventional DC will also run exceptionally well under DCC.
Precautions to Take When Installing the Decoder:
Although the H15/16-44 decoder has many internal safeguards to
prevent damage, you must not allow any metal part of the locomotive to
touch surface components of the decoder other than the pickup pads on
the decoder that connect to the wheel-sets, the headlights, and the
motor. Any contact to other parts of the decoder can cause a direct
internal short circuit and destroy the DCC decoder.
The H15/16-44 decoder is not completely protected against static
electricity and has sensitive electronic parts. When installing this
decoder in your N scale locomotive, it is recommended that you wear a
grounded anti-static wrist strap. Also be careful in handling the decoder,
especially in the area around the top rear part of the decoder (the area
where the microprocessor is located).
