Configuration of smoke generators

Smoke generators without fan

(Example:

„Seuthe“ 18 V)

In addition to a simple ON/OFF function via a function output of your choice, the smoke intensi-
ty can also be programmed to change between

standstill, cruising

and

acceleration

This requires the smoke generator to be connected to one of the function outputs

FO1… FO8

(FO7 and F8 only with SW version 34 or higher)

and the selected output must be programmed for

the desired effect with the associated “effect CV” (with CV #127 for FO1, CV #128 for FO2
etc.); in this case for load dependent smoke of steam engines (effect code “72”) or load de-
pendent smoke of diesels (e

ffect code “80”).

The smoke generator characteristic is defined by CV #137, 138 and 139 and must be pro-
grammed with appropriate values otherwise the smoke generator will not produce any smoke.

The values in CV #137

FO4, FO5 or FO6; referred to below as FOx), pro-
vided

a “smoke function” for a diesel or steam en-

gine (value 72 or 80) has been selected in the asso-
ciated CV #127

– 132:

CV #137: PWM of FOx at standstill

CV #138: PWM of FOx at cruising speed

CV #139: PWM of FOx at acceleration

(PWM = Pulse With Modulation)

EXAMPLE: - Typical characteristic for a track voltage set around 20V with above
smoke generator:

CV #137 = 70 .. 90:  little smoke at standstill.
CV #138 = 200: The smoke intensity is increased to about 80% of its maximum capacity begin-
                          ning with speed step 1 (at very low speed), which produces relative heavy
                          smoke.
CV #139 = 255: The smoke generator is driven to its maximum under heavy acceleration, which
                          results in thick smoke.

Synchronized steam chuffs or typical diesel smoke (with exhaust fan):

With the built-in fan, synchronized steam chuffs or driving-state dependent diesel smoke can
be generated without adding additional electronic components.

The heating element of the smoke generator is connected

– as in the example above with the

“Seuthe” generator – on

FO1…FO8

and configured with the appropriate CV for the desired ef-

fect (i.e. “72” for steam or “80” for diesel).

The fan is connected to the

“fan output”

of the large-

scale decoder; see chapter “Installation

and wiring”, section “Special Connection for Smoke Fan”).

The fan speed is adjusted by PWM; the value in CV
#351 defines the effect at steady speed.

= 128: Fan is driven at half the voltage at cruising
speed.

#352

motor starts and during

acceleration

For DIESEL engines

The exhaust fan is set to a higher speed (usually top
speed) for generating the typical exhaust puff during
motor starts as well during hard accelertions.

= 255: Fan receives maximum voltage at start-up or
accelerations.

If a smoke generator is controlled by one of the effects
“010010xx“ or „010100xx“ in CV’s #127 to 132 (for one
of the function outputs FO1 to FO6), the output turns
itself off automatically after the time defined in this
CV, in order to protect the generator against overheat-
ing.

= 0: no automated turn-off

= 1 to 255: automatic turn-off after 25sec/unit, which
offers a maximum time of about 6300sec = 105min.
