System of operation
This high power electronic smoke generator module is intended to be used in any land vehicle
or boat. It is designed to be combined with the Benedini TBS Mini V1 and V2 sound unit
(NOT TBS5!). It provides for exhaust smoke to be generated both proportionally and
synchronised to the speed of the vehicle and the engine sound emitted by the Sound Unit. The
smoke controller has galvanic isolation from the sound module and the receiver.
Oilbased smoke unit, Version II www.benedini.de Page: 1
The method of operation is for smoke fluid to be heated by the heater elements (the smokers)
and the smoke produced blown out of the smoke accumulation reservoir by the fan in a
volume dictated by the speed of the vehicles motors/engine sound module. The system
although simple in its operation is totally reliable and effective and produces a scale effect
that will enhance any models appearance.
The complete unit consists of a speed controllable fan, a smoke + oil box, a control unit and
two or four smoke elements (smokers) dependant on the scale of the vehicle it is fitted to that
are operated and that are switched on and off electronically according to the speed of the
motor(s).
During starting or accelerating a large volume of smoke will be produced. When the model is
moving, all heating elements are active and the fan speed is electronically adjusted
proportionally to the model speed to deliver a realistic volume of exhaust smoke.
Pictures below show a transparent plastic housing for internal view but are also valid for the
metal version.

Installation and operating advice
1. Smoke exit outlet can be drilled horizontally (standard) or vertically in the smoke box
2. Smoke outlet tube installation:
The tube(s) must have a permanent rise for allowing condensed oil dust running back into
the box. Prevent any sagging of the tube, otherwise condensed smoke can close the tube.
The tubes should be feed STRAIGHT to the exhaust without many corners between.
If two exhausts are desired, use a tube for each of them. T-fittings are not recommended.
If very long exhaust tubes are necessary, a radial fan can be used instead of the standard axial
fan but requires more installation space! Such a fan can be ordered separately.
Various different smoke effects can be achieved by experimenting with the exhaust pipe(s)
and their fittings. The effect may not however be ideal for all models and the purchaser is
advised to experiment until they are satisfied with the result.
3. The box must have a certain inclination in the model !
The refilling side of the smoke box must be slightly raised. This ensures proper indication by
the filling tube if the oil level runs low.
4. Smoke oil filling
Initial smoke oil filling:
a) Soak the according refill volume by the syringe out of the oil container.
→ See box depending filling volumes in the technical data section !
b) Fill the smoker box through the filling tube.
c) Empty the smoker box again by soaking the oil out the box through the filling tube. Use
again the syringe.
d) Now the minimum oil level is remaining in the box.
e) Refill the box with the recommended oil volume.
Refilling smoke oil before/during operation:
a) Empty the smoker box by soaking the remaining oil out of the smoker box, by using the
supplied syringe. This avoids overfilling!
b) Refill the box with recommended oil volume.
→ See box depending filling volumes in the technical data section !
!!! Refill indication !!!
If smoke oil runs low during operation, smoke exits the refill tube. This can be seen clearly.
Refill the according oil volume directly !
!!! NO WARRANTY ON BURNED HEATING ELEMENTS OR
OTHER DAMAGES DUE TO OVERHEATING !!!

Make sure the refill tube lasts not less than 5 mm until bottom of the housing.
This MUST be to ensure refill indication by smoke.

Hints for electrical installation
1. The +battery cable MUST be fused ! Fuse is included → see below.
2. The recommended diameter for the plus lead going to the heaters is 0.5 qmm.
3. The brown AND black lead coming from the controller must be connected BOTH to
Minus battery !!!
4. 24V operation is only possible with 4 heaters. Two of them are connected in series.
In addition a pre resistor is necessary for the 12V fan! See diagram above.
12V operation is possible with 2, 3 or 4 heaters.
→ less current + less oil consumption → LESS Smoke !
The + battery cable MUST be fused ! Fuse holder and fuse are included in the kit.
Type of fuse: 5A fast characteristic
Any damages in the smoke controller area shown below are definitely out of any
warranty !!!
Such damage results from damages on the
heating elements caused by overheating.
Watch oil level !
If connected to the TBS5 sound unit
→ see last page !!!
