10A dual speed controller 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 ve-
hicles with differential drive. In addition, there are variants for historical
tracked vehicles without tableturn as well as the possibility of inertia simu-
lation.
The controller is equipped with BEC and has an EMK brake, which is released
in the middle position of the throttle and steering stick. The braking effect
can be set either via an RC channel, or fixed.

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 6.5V to 24V.
This means that the controller works with the 6 cell NC packs commonly
used in the RC car sector, but also with lead batteries up to 24V. Two stan-
dard automotive fuses protect the model and the battery from excessive
currents.
The controller has a built-in BEC circuit to power the receiver from the drive
battery.
Please note that the removable BEC current decreases as the supply voltage
increases.
To disconnect the internal BEC regulator from the receiver supply, a jumper
must be removed.
As a failsafe function, an extensive plausibility check of the transmitter
signals is integrated in the software.
In addition, the controller has a temperature monitoring of the output
stage.
It switches off at 75°C and can be switched on again at 65°C and above.
To do this, the transmitter sticks must be set to the neutral position to
prevent a sudden start after the controller has cooled down.
2.1 Technology
The controller is microprocessor controlled. The processor works with
16MHz clock frequency.
The output stage is constructed from N-channel MOSFETs, which have an
inrush resistance of only 0.008 ohms and a continuous current capability of
60A. To make effective use of the low internal resistance, the output stage
transistors are driven by sophisticated MOSFET push-pull output stages
with integrated charge pump.
Under normal ambient conditions, a continuous current of 10A is achieved.
The controller operates with a PWM frequency of 16kHz.

3 Functional description
3.1 Manual control
A radio remote control with at least one proportional channel is required
to control the module. To use all functions, four RC channels are required.
3.1.1 Channel 1 - proportional forward/back
Direction of rotation for the motor. From the throttle channel is also derived
reverse light on/off, brake light).
3.1.2 channel 2 - proportional left/right
The control of the turn signals is derived from this channel. It is usually
connected to the steering channel with a V-cable, parallel to the steering
servo. If the channel is not connected, the turn signals only function as
warning turn signals.

4.1 Battery connection
Fahrakku plus (+)
Fahrakku minus (-)
Figure 1: Assignment of the connector for power supply
Power is supplied via the green, plug-in screw terminal. Please pay atten-
tion to the correct polarity of the supply voltage! (see figure 1).
It makes sense to include a switch in the positive supply line to the battery
to switch the model on/off. Never switch the minus in RC model building,
because the minus also the reference potential of the servo signals.
There are two automotive fuses for the motor output stages on the circuit
board. They are pluggable and can be easily replaced if necessary.
If one of the power stage fuses has blown, the BEC still works and the LED
indicates the function. However, the corresponding motor output stage
no longer supplies power. In addition, the BEC circuit also has a fuse. This
is soldered onto the circuit board. If this fuse has blown, the BEC no longer
supplies voltage and the controller no longer shows any function.
4.2 Connecting the motors
Black, plug-in screw terminals are provided for the drive motors. One
motor is connected to each screw terminal. The motors must be radio
interference suppressed, as is usual in model building.
4.3 Connecting the servo cables
The controller is equipped with JR servo cables. The pinout is shown in
figure 2.

4.4 BEC jumpers
The controller contains a BEC circuit that generates a regulated voltage of
5V from the voltage of the drive battery to supply the receiver and servos.
Since in function models often several controllers with BEC are installed,
but the parallel operation is problematic under certain circumstances, the
connection of the installed BEC to the receiver can be disconnected. Two
green jumpers are used for this purpose.
If the jumpers are inserted vertically, the internal BEC voltage is passed on
to the receiver and from there to the servos.
If the jumpers are inserted horizontally (or are not inserted), the voltage is
not passed on. In this case, another module must supply the receiver with
power.

4.5 Scalebus operation (optional)
As an alternative to control via the receiver and the servo cables, the
controller can also be controlled via the scale bus. To do this, the controller
is connected to the other modules with the scale bus cable (white, four-pin
connector).
For example, the FO module TVC-MF-10 can control the controller. The
controller switches to scale bus mode if no servo signal is present at the
two servo cables when it is switched on. Accordingly, the servo cables must
not be plugged into the receiver during scale bus operation.
In scale bus mode, the controlling module specifies the mixing function.
Therefore, a controller for a half-track vehicle can also be operated with an
FO module for a battle tank.
The controller then works as a full track mixer.
Not only the information for controlling the drive motors, but also the
information for the auxiliary drives is sent via the scale bus.
If no jumper is plugged in, the information of the drives is output.
If coding bridges are plugged into servo cables 1 or 2, the motor outputs

TVC-B10

are controlled as specified in the description of the FO module.
Example tracked vehicle:
1. No coding jumper plugged
→Controller works as drive controller (drive chains)
2. coding jumper plugged into servo cable 1
→ Controller works as tower control (barrel elevation and tower rota-
tion)
It is of course possible to connect several controllers to the scale bus. It is
also possible for two controllers to output the same information.

5 Commissioning
5.1 Startup
1. Connectconnect the drive battery on the transmitter the throttle and
control levers to the center position (the corresponding trim as well).
on the receiver. The green LED lights up for approx. 1s.
2. The green LED on the board flashes until the controller has detected
the center position of the channels. If zero point detection is not
possible, the LED does not light up. The zero point is not determined
again until the receiver is switched on/off.
3. If the green LED is continuously on, the vehicle is ready to drive.
This automatic calibration is done in this way at every switch-on. I.e., the
position detected at power-up is stored as the neutral position. This applies
to both steering and speed.
5.2 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
with different polarity in order to drive in one direction.
Of course the correction of the driving direction can be done directly on
transmitters with the servo reverse setting. If the transmitter does not
have this possibility, you can proceed as follows:
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

5.3 EMF brake
The controller has an adjustable EMF brake. It is activated by moving the
throttle and steering sticks 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.
If you want to change the braking effect, you must press the button. The
button is located between the light connector and the jumpers for the BEC.
Use a thin stick made of plastic or wood to press the button. The push
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 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.
5.4 Error states
Normally, the green LED is permanently on. If the controller detects an
error, it indicates this by briefly flashing the green LED n times. In addition,
the red LED lights up. All error conditions lead to the motor being switched
off.

5.5 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 15.
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.
5.5.1 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.
