Application Hints; Operation With The Intellibox - Viessmann 5242 Manual

The speed of the locomotive with load control
is lower than without it:
The load regulation needs a reserve for special
demands like driving an ascent, otherwise the
speed locomotive slow down.
7. Application Hints for the De-
coders 5242 and 5243
Connecting an auxiliary function
Before you connect an auxiliary function (e.g.
steam generator, see fig. 6 at page 19) you must
set the light outputs for non-directional operation.
This is achieved by setting bit 0 (value 1) in the
user-configuration register 1 (CV56).
Once this is done, F0 (light) switches only the light
output connected to the white wire, i.e. the head-
lights are switched on or off with function key F0.
This output is now non-directional. The output with
GB
the yellow wire is activated through the function in
CV58 (e.g. at value 1 with F1). In this manner you
switch on or off the auxiliary function (e.g. steam
generator).
Please note, that the maximum current of 150 mA
for output B must not be exceeded! By this con-
nection the auxiliary function will get only the half
of the current (see chapter 2.2, 4 at page 11).
You have to select the steam generator type by
its operating voltage: If there is 21 V track voltage
(like the Intellibox, Twin-Center, Roco Lokmaus)
the steam generator should also be designed
for 21 V. For the "Set 1" from Lenz (track voltage
about 15 V) you should use a steam generator
designed for 14 – 16 V operating voltage with the
connection described at chapter 2.2, 4 at page 11.
Tip: When you set CV50 to value 128, you can
reduce steam generation (e.g. while the
locomotive is standing) by activating F4.
7.1. Connecting Interior Light-
ing in Rail Cars or Multiple
Units
There are two choices for connecting interior light-
ing (see fig. 7 at page 19):
◆ The headlights of the powered rail car are
controlled directionally by function key F0, that
means, when function F0 is switched on, the
headlights are on when driving forward, the rear
lights are on when reversing while the interior
lighting is also switched on.
◆ The headlights of the powered rail car are con-
trolled non-directionally, that means, when func-
tion key F0 is switched on. The lights are on
16
at the front and rear in both directions. Interior
lighting can be switched on and off separately
by setting the function key in CV58 (e.g. F1).
Directional headlights
The function outputs for the headlights are factory
pre-set for directional operation. Programming is
done in the user-configuration register 1 (CV56).
Delete bit 0 (represents value 0) in this CV.
In order to switch on the interior lighting when
either headlight is on you need two additional
diodes (Viessmann art.no. 6834, 10 pieces per
pack). Solder the cathode of the diode (marked
with a ring) to the yellow or white wire. Connect all
the anodes to one of the poles of the interior light-
ing. Connect the other pole of the interior lighting
with the blue wire.
When function F0 is switched on, the headlights
are multidirectional, while the interior lighting is
always on (non-directional).
Non-directional headlights
The connection of the interior lighting corresponds
to an auxiliary function (see fig. 6 at page 19).
Simply replace the auxiliary function with a lamp.
8. Operation of the Decoder
with Intellibox or TwinCenter
The Intellibox is preset to the Märklin-/Motorola
format. If you want to use DCC decoders, you
have to change the format as per instructions in
the Intellibox manual (special option 25 = 1, spe-
cial option 907 = 4 or 5). If the Intellibox is not set
to DCC operation, locomotives with DCC decod-
ers may start moving uncontrolled after switching
on the Intellibox, because DCC decoders interpret
the Motorola signal as an analogue signal. Set to
"N" gauge to limit the track voltage to 18 V. This is
kind to the motors of your locomotives.
Advice to the programming track: The first test
after the built-in of a decoder should be performed
on a track with a current limiter. First switch the
Intellibox or the Twin-Center to the programming
mode! You will hear the click of a relay inside the
command station. Only after that you can put the
locomotive onto the programming track without
risk for the decoder and read it out.
The Intellibox recognizes long addresses and
automatically switches to extended address mode
(CV29, bits 5 = 1). Therefore the decoder does
not operate with its short address. To activate the
short address, delete bit 5 in CV 29. Just program
the short address and the decoder will delete
CV29 / bit 5 automatically.
