TVC-B30L
30A dual speed controller with light control for 1/10 scale and
larger 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 operates with
16MHz clock frequency.
The output stage is constructed of N-channel MOSFETs, which have an
inrush resistance of only 0.008 Ohm and a continuous current capability of
60A. Three of these transistors each form a power stage branch, enabling
peak currents of up to 180A. 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 30A 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.
3.1.3 Channel 3 - Light mode control
This channel can be used to switch the all-round light and the hazard
warning lights, as well as two freely assignable outputs. If the channel is
not used, the rotating beacon is permanently active and the hazard lights
are switched off. The two freely assignable outputs are also switched off.
3.1.4 channel 4 - EMF brake
This channel can be used to set the braking effect of the holding brake. If
this channel is not connected, the brake function can be permanently set
on the controller.

3.2 Function of light mode switching
There are two light modes which are controlled independently by RC chan-
nel.
3.2.1 Light mode 1
Light mode 1 controls two outputs for universally usable lamps (auxlight
1 and 2). They can be used, for example, for the low beam, the front
headlights or searchlights.
Light mode 1 is switched on by tapping the control element from the
center position to
front
. The modes are switched on by briefly tapping the
channel (1 � 2 � 3 � 4 � 1, etc.). Long pressing (approx. 2s) always selects
”state 1” (all off).
state 1 2 3 4
auxlight 1 off on off on
auxlight 2 off off on on
Table 2: Light mode 1
Light mode 2 Light mode 2 controls the automatic light functions for the
turn signal and the rotating light. In the different light modes, the lamp
outputs are switched as shown in the table.
By pressing the key for a long time (approx. 2s), ”state 1” is always selected.
After switching on, the model is in light mode ”state 1”.

state 1 2 3 4
Hazard warning lights off on off on
Rotating light 1,2,3,4 off off on (Running lights) on (Running lights)
Table 3: Light mode 2
Note
Typically, one uses a channel with three-position pushbutton on
the transmitter side (A pushbutton with automatic center position). Propor-
tional channels with sliding or rotary potentiometers make the selection
of the light mode more difficult, because the switching should be done by
short actuation with reset to the center position. This is difficult to handle
with sliding or rotary potentiometers.
3.3 Drive dynamic functions
3.3.1 Reversing lights
The reverse light output is turned on as soon as the throttle lever steers
backward. Once the throttle is in neutral or straight, the reverse light is
turned off.
3.3.2 Around light
The rotating light runs at approximately 1.5 revolutions per second. It is
turned on/off by light mode 2.
3.3.3 Indicator Left + Right
From a minimum speed of approx. 10% of the maximum speed, the auto-
matic blinker switches on. When the steering is in the right position, the
right turn signal is flashing, when the steering is in the left position, the left
turn signal output flashes with a frequency of approx. 1Hz. The automatic
turn signal is only active in the driving mode. The hazard warning light can
be switched on or off by the light mode 2.
