EMC declaration
This product is developed in accordance with the European standards
EN 55014 and EN 50082-1, tested corresponding to the EC - directive
89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) and
meets legal requirements.
To guarantee the electromagnetic tolerance you must take the
following precautions:
§
Connect the transformer only to an approved mains socket installed
by an authorised electrician.
§
Make no changes to the original parts and accurately follow the
instructions, circuit diagram and PCB layout included with this manual.
§
Use only original spare parts if you have to repair the kit or the
ready-built module.
Operation overview
The decoder is designed for operation in Motorola II format and can be
adjusted to one of 255 addresses. It evaluates the digital data sent by the
central unit to its address and transmits it to the locomotive. In Motorola I
format it is possible to operate the decoder, but the programming of the
parameters and the controlling of the functions is restricted.
Driving of the motor
The motor is driven with a PWM of 32 kHz. This guarantees a soft and
constant run of the motor. With that the decoder may be used with
coreless (Faulhaber) motors as well.
Load control
At constant motor voltage, additional loads (e.g. running up a gradient,
coupled carriages) cause the locomotive to slow down or even come to
a standstill. If the load control is active the motor voltage varies to keep
the locomotive operating at constant velocity at a given speed level,
independent of additional loads. When programming the decoder the
load control can be switched on or off.
