Seuthe smoke generators have considerable production toler-
ances. Therefore, it is possible that one unit works perfectly
well while another does not. Type of distillate and filling level
have an influence as well.
c) Setting the decoder output
For correct smoking action you should set the AUX output to
„Dimmer“ as well as full „Brightness.“ More info in chapter
12.
d) Connecting the smoke generator
Most smoke generators are wired against the chassis (ground).
Therefore the smoke generator only receives current in every
second half cycle. How much power gets to the smoke genera-
tor depends on your command station and the digital protocol.
Generally, Seuthe type 11 is recommended, but it does not get
enough power and therefore does not smoke satisfactorily.
There are two options on how to solve this problem:
Solution 1: Using the Seuthe No. 10. This type is intended for ana-
logue operation and draws a relatively high current. Subject to its
tolerance levels, it may trigger the overload protection of the de-
coder. In this case, you must wire a relay (ESU No. 51963) into the
circuit or you slightly reduce the „Brightness“ of the output.
Solution 2: Using the Seuthe No. 11. Do not wire it against the
chassis (ground) but rather use the blue wire for the second pole
(„U+“). This prevents the asymmetric track signal from interfering
with the smoke generator. It represents the best solution but is
sometimes a bit difficult in terms of wiring.
6.9.7.1. HALL Sensor IC
A Hall sensor is an electronic circuit that responds to an alternating
magnetic field similar to a reed switch. Hall sensors are easier to
adjust since the distance between sensor and magnet is not criti-
cal. A commonly used hall sensor, that can be purchased via mail
order is the TLE4905 by Siemens / Infineon. There are also many
compatible devices on the market. The terminals have to be wired
to the LokPilot as shown in figure 19.
6.9.5.1. Servo outputs
AUX7 through to AUX10 may be used for “normal” loads but
are also capable to drive RC servos. All commercially available RC
servos with a positive pulse are suitable. Please observe the cor-
rect polarity when connecting the servos. Prior to controlling the
servos you must set the outputs to “Servo”. Please refer to chapter
12.3.7. for more information.
6.9.6. Suitable Smoke Generators
Unfortunately, it is not an easy task to find the right smoke genera-
tor for each locomotive. The amount of smoke generated depends
on the following factors:
a) Track voltage
The track voltage varies depending on the command station.
Therefore, it is possible that a locomotive generates smoke
when driven by one digital system but does not generate any
smoke with another system. Even 1V variation makes a big
difference.
b) Type and tolerance of the Seuthe smoke generator and the
smoke distillate
