WIB-33.2
English
Operation in analogue mode
The carriage lighting WIB-33.2 can also be used in analogue model
railway layouts. 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.
Switching the LEDs and 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.
In analogue layouts supplied with d.c. voltage, the function outputs
switched with F0 are switched on and off according to the direction of
travel. This is not possible in analogue a.c. layouts as the decoder does
not recognize the impulse for changing the direction of travel.
Activating the LEDs
The eight LEDs can be switched on and off individually, in groups or
corporately. By programming the decoder accordingly you can
set the LEDs´ brightness individually for each LED,
switch the LEDs according to the direction of travel,
simulate fluorescent tubes when switching on the LEDs,
set the duration of the switching on of the fluorescent tube
simulation until reaching a constant light and a defective fluorescent
tube individually for each LED.
You can switch from standard lighting to orientation light with a
function key (e.g. for holded carriages or sleeping cars). The orientation
light´s brightness is set corporately for all LEDs.
Instead of programming the LEDs´ brightness with a digital control unit
you can set it with a trim-pot (corporately for all LEDs). The brightness
programmed via CVs or register remains active, the settings at the trim-
pot only alter the brightness with a factor valid for all LEDs.
Activating the addtional function outputs
There are three outputs for external loads on the PCB controlled by the
integrated decoder. The output AUX2 is designed for the connection of
LEDs for the back lighting. The necessary series resistors are integrated
on the PCB.
The two outputs AUX1 and AUX3 are available e.g. for the connection
of additional lighting (e.g. in the driver´s cabin or in the toilet cabin) or
electric couplings. Their maximum current is 300 mA.
It is possiblie to switch all outputs dependent on the direction of travel
and to dim them.
Besides, the two outputs AUX 1 and AUX 3 provide:
Kick function for special types of electric couplings needing a
reduction of the connected voltage after the switching operation in
order to protect the coupling.
Random switch switching on and off the output in irregular intervals
(e.g. for the lighting of a toilet cabin).
Connecting a light dependent resistor
When a light dependent resistor is connected, the LEDs and the
decoder´s function outputs can be switched on and off automatically
depending on the surrounding lighting. The sensivity is set via CVs or
registers. You can activate the dim switch with a function key.
The dim switch effects only those outputs switched on. As soon as the
outputs have been switched off by the dim switch they cannot be
switched on with a function key. In this case the dim switch has to be
deactivated first.
With the initial settings the LEDs are switched on as soon as the
surrounding lighting under-runs the set limit value. It is possible to
invert this functionality, e.g. in order to automatically switch off the
lighting in a shadow station.
Flickering protection
An integrated smoothing capacitor supplies the LEDs when short
current interruptions occur, which prevents the lighting from flickering
when points or smudges on the rails are crossed. In case the integrated
smoothing capacitor is not sufficient, you can connect an additional
external bridging capacitor with a minimal voltage sustaining capability
