Overload Protection (Except Ld-G-31 Plus) - tams elektronik 30 plus Series Manual

Locomotive decoders of the series 30 plus
4.8. Overload protection
The locomotive decoders LD-G-33 plus, LD-G-34 plus and LD-G-36 plus
have an overload protection, which prevents them from overheating
when exceeding the maximum motor or total current.
As soon as the maximum motor or total current is exceeded, the
decoder automatically temporarily switches off. This operation will be
repeated until the overload has been eliminated.
When exceeding the maximum current at the output only (but not the
total current of the decoder) the decoder´s overload protection is
without effect, the concerned output will be damaged.
Attention:
!
When a short circuit occurs that bypasses components on the decoder
either to each other or to track voltage, the overload protection is not
effective. Examples:

contact between the decoder and the rails or metal parts of the
vehicle;

contact between not-isolated decoder connecting wires and the rails
or metal parts of the vehicle;

contact between accessories connected to the common return
conductor of the decoder and the rails or metal parts of the vehicle.
Attention:
!
Malfunctions of the locomotive motor (e.g. the so-called "sparking of
the brushes") can cause extreme interference current, possibly
damaging components on the decoder. The decoder´s overload
protection is without effect with this extremely high current.
