Locomotive decoders of the series 30 plus
English
Analogue mode
The locomotive decoder can also be used in analogue model railway
layouts run with a D.C. or A.C. speed control. When putting the vehicle
on the rails the decoder recognizes automatically if it is run in analogue
or digital mode and sets the corresponding operation mode. The
automatic recognition of the analogue mode can be switched off.
Caution:
Old analogue driving transformers (e.g. models in a blue housing
from Märklin**) are not suitable for use with digital decoders in
analogue operation! These transformers have been designed for the
older supply voltage of 220 V and, due to construction, generate very
high excess voltage impulses when changing the driving direction.
When using them with the modern supply voltage of 230 V too high
excess voltage impulses can occur, damaging electronic parts on the
decoder. For that reason only use driving transformers designed for a
net voltage of 230 V.
Switching the function outputs on or off is not possible in analogue
mode. They can be programmed so that they are either switched on or
off in analogue mode. The effects set for the outputs are active in
analogue mode as well.
Outputs to be switched with F0 are switched on or off in analogue mode
according to the direction of travel. When operated in analogue d.c.
layouts this applies only to lamps or accessories where the return
conductor is connected to the decoder´s common return conductor for all
function outputs.
The decoders´ load control is also active in analogue mode. The set
maximum speed also limits in analogue mode the maximum speed of the
locomotive.
