100A dual speed controller for RC tracked vehicles
The controller contains all components for controlling two DC motors in a
tracked vehicle.
The behavior of the integrated mixer can be set for different vehicle types.
The controller can thus be set for full tracks, half tracks and wheeled
vehicles with differential drive. In addition, there are variants for historical
tracked vehicles without tableturn as well as the possibility of an inertia
simulation.
The controller has an adjustable EMF standstill brake, which is triggered in
the center position of the throttle and steering stick.

1 Note
Installation of the module requires intermediate to advanced modeling
skills. Soldering skills are required to connect the wiring. Inexperienced
modelers and persons aged under 16 years old should seek the assistance
of an experienced modeler. Always switch off power when working on
the wiring. Especial take care when connecting more than one receiver
energy source. Prevent the device from getting wet. Check loads before
connecting them to the modul at a current limited, or fuse protected
source.

2 Introduction
The controller is designed for an input voltage range from 12V to 36V. Two
standard automotive fuses (strip fuse) protect the model and the battery
from excessive currents.
In addition, the controller has electronic overload protection (
2t
monitor-
ing) and electronic temperature monitoring of the power output stage.
2.1 Technology
The controller is microprocessor controlled. The processor works with
16MHz clock frequency. The software is coded in C and assembler.
As a failsafe function, an extensive plausibility check of the transmitter
signals is integrated in the software.
The power amplifier is built with N-channel MOSFETs, which have an inrush
resistance of only 0.001 Ohm and a current capability of 180A. To make
effective use of the low internal resistance, the output stage transistors are
driven by sophisticated push-pull MOSFET output stages with integrated
charge pump.
Under normal ambient conditions, a maximum continuous current of 100A
is achieved. The controller operates with a PWM frequency of 16kHz.
. To prevent ground loops and resulting interference, the servo inputs
are galvanically isolated. Accordingly, the receiver not is supplied by the
controller.
The housing of the controller is CNC milled from aluminum.

3 Installation
3.1 mounting
The module can be screwed onto a flat surface with max. six M5 screws.
Ideally, the module should be mounted on a large metal surface to improve
heat dissipation.
The housing of the controller is on the ground potential.
Figure 1: Connections overview
3.2 Driving battery and motors
High, high-frequency currents flow between the drive battery in both
directions. Provide a low-resistance connection between the drive
battery and the controller and use a suitable switch or a high-current
relay. Use only fuses for protection. We strongly advise against the
TVC-B100
7
© SGS electronic 2006-2023
use of electromagnetically tripped circuit breakers, anti-flash devices
for limiting the starting current, rechargeable batteries with electronic
current limiting, etc. We strongly advise against this.
The drive battery and drive motors are connected to the M5 screw terminals
via ring cable lugs.
Insulate the ring cable lugs with the enclosed heat shrink tubing to avoid
short circuits. Clamp the enclosed ring cable lugs in the following order
(from bottom to top):
1. washer
2. ring cable lug
3. washer
4. Toothed lock washer
5. nut
Use a suitable ring or socket wrench to tighten the nut. Tighten the nut
so that the toothed lock washer is compressed by approx. 0.5 mm. When
tightening the nut, align the line in the desired direction when tightening.
Please do not twist the already tightened ring cable lug by force.
Too much torque on the nut can damage the PCB!
A mix-up of the connection terminals for the power supply must be
avoided at all costs!
It makes sense to provide a switch at the supply line from the battery
to switch the model on/off. Commercially available battery switches or
high-load relays are suitable for this purpose. The motors must be radio
interference suppressed, as is usual in model building.
3.3 connecting the receiver
The controller feeds itself from the drive battery with a built-in switching
regulator. The three servo lines are galvanically isolated from the controller.
The receiver is therefore not supplied with power from the controller, but
must be supplied from another power source.
This is usually from a receiver battery. The input circuit also requires the
receiver supply voltage (approx. 15mA) and obtains this from the receiver
TVC-B100
8© SGS electronic 2006-2023
battery through the servo leads.
The servo cables are labeled.
3.4 EMF brake
The controller has an adjustable EMF brake. It is activated by moving the
throttle and steering stick to the center position.
The braking effect with which the brake is applied is indicated by the yellow
LED. The longer the yellow LED is on, the stronger the braking effect.
• LED Off corresponds to 0% braking effect.
• LED On corresponds to 100% braking action.
note
When the brake is active (stick in center position and braking effect
set greater than 0%) you can hear a hiss from the motors. This is the
modulated braking current. As soon as you drive off or deactivate the
brake, the noise disappears.
The adjustment of the brake can be done in two ways: Via an RC channel of
the controller (so it can be changed via the transmitter at any time) or via
a button on the controller. Adjustment via an RC channel of the controller
Here the braking effect is adjusted directly via the transmitter. As soon as
you press the corresponding slider/knob, you will see that the pulse/pause
ratio changes.
You can use it at any time, for example, light braking and further increase
the braking effect.
If you have a channel free on your RC system, we recommend this method.
Make sure that they do not stop from full speed with full braking effect,
this puts a lot of stress on the entire drive train.
Without RC channel with button on the controller If you want to change
the braking effect, you have to press the button. There is a small hole
under the three LEDs for this purpose. Use a thin stick made of plastic or
wood to push the button. The button has a clearly noticeable pressure
point. If you move the throttle in one direction the on phase of the yellow
LED gets longer and longer, in the other direction shorter and shorter
until it is completely off. The stronger the lever deflection, the faster the
TVC-B100

adjustment.
The green LED lights up continuously as soon as you take the lever out of
the neutral position to indicate that the controller is making a change.
If you press the button again, the brake setting is saved and is retained
even after switching off and on again.

4 Commissioning
4.1 startup
1. Put the throttle and steering levers into the receiver.
2.
If the brake is to be adjusted via the transmitter, it must also be
plugged into a free channel of the receiver.
3. Switch on transmitter
4.
Set brake, throttle and steering levers to center position (The corre-
sponding trim as well).
5.
Turn on receiver power supply. Note that the controller does not
provide receiver power (BEC voltage) due to galvanic isolation.
6. Switch on the drive voltage (= supply voltage of the controller).
7.
The LED on the board flashes until the controller has detected the
center position of the channels. If zero point detection is not possible,
the green LED flashes and the yellow one is permanently on. A new
determination of the zero point is only done after switching on/off
the driving voltage. If the driving voltage is interrupted, please wait
until the LEDs on the controller have gone out. This takes some
seconds, because of the integrated switching regulator and the large
capacities. the green LED is on continuously, the vehicle is ready to
run.
This automatic calibration is done in this way at every switch-on. I.e. the
position detected at switch-on is stored as the neutral position. This applies
to all channels except for the brake channel.
4.2 error acknowledgement
The controller shuts down in the event of overtemperature,undervoltage,
overvoltage, excessive motor currents, excessive current source impedance,
and loss of receive signal. It indicates these error conditions by flashing
the green LED (blink code) and lighting the red LED.
Special attention should be paid to the overvoltage error during regenera-
tive power supply. A regenerative overvoltage fault is triggered when the

Table 2: Error codes
power from the motor is prevented from being fed back to the battery via
the controller. Generally this is called too high impedance of the power
source. In particular, this can be caused by, among other things:
1.
too small wire cross-section between battery and controller. circuit
breakers between battery and controller (do not use circuit breakers
for alternating current)
2. batteries with built-in electronic current limiter
3. operation on an alternator without buffer battery
4. operation on an electronic power supply unit
5. high contact resistance in the connections
If this error has occurred once, components and connections should be
checked carefully. Since this error is very critical, it can only be acknowl-
edged by switching the supply voltage off/on.
4.3 Correct driving direction
The direction of travel depends on the mechanical arrangement of the
engines in the vehicle. Usually, the motors are mounted so that the motor
shafts are in opposite directions. As a result, the motors must be connected
TVC-B100
12 © SGS electronic 2006-2023
with different polarity in order to travel in one direction.
Of course, correcting the direction of travel can be done directly on trans-
mitters with the servo reverse setting. If the transmitter does not have this
facility, the following procedure can be followed:
1.
model moves forward when steered backward and vice versa: Change
connections on both motors (reverse polarity).
2.
Model moves left when steered to the right and vice versa: Change con-
nections from both motors, reversing polarity. (connecting line from
motor 1 to motor 2 and vice versa).
3.
The directional control is set to neutral, but the model does not drive
straight ahead: Correct with steering trim
4.4 Scalebus operation
As an alternative to control via the servo connectors, the controller can
also be controlled via the Scalebus. To do this, connect the controller to
the other modules using the scale bus cable (white, four-pin connector).
For example, the FO module TVC-MF-10 can control the controller. The
controller switches to Scalebus mode if there is no servo signal on the
servo cables when it is switched on.

4.5 Changing the mixing function
Different vehicles and transmission types need different mixers. In the
past, we offered different versions of the controller (”OG”, ”CM”, ”HT”, etc.).
With this controller, you can now define the mixer function yourself. An
overview of the available mixers is shown in table 3 on page 14.
Notes
Note that the maximum current consumption of mixers with table-
turn is not significantly higher because the drives work against each other
in tableturn.
Be careful when operating with inertia simulation. The vehicle then natu-
rally reacts with a delay to the commands of the radio remote control.
4.5.1 How to change mixer function
1.
Connect everything as described under commissioning and switch
on the transmitter.
2.
press the button when switching on the controller. The setting mode
is indicated by the red and yellow LEDs lighting up.
3.
With the throttle and steering channel you can now select nine posi-
tions by setting the sticks in left/right stop or leave neutral position.
The position number is indicated by the red LED flashing while the
green LED is lit. If the green LED goes out, the cycle starts again.
4.
For example, if the red LED flashes three times, mixer number three
of the table is selected. save this, hold the sticks in position and press
the button again.
5. Then release the stick. Now the mixer is selected and saved.
