FUTABA MC850C Manuals

[MC850C Technical Data] (Specifications are subject to change without prior notice.) MOUNTING PRECAUTIONS Accessories • Schottky diode (for motor) • Capacitors (for motor) • Double sided tape • Silicone flex wire (Red,Black,Blue) • Heatshrink tube, red (x1), black (x1) • Miniature screwdriver (Use to press the pushbutton switch.) Important: Because the MC850C has pure race competition specifications, it is designed so that it is difficult to operate the protection circuits. Use at an overload may cause trouble. Incorrect power supply polarity or a power supply or motor short circuit may cause the MC850C to burn out. Install the receiver and receiver antenna away from the amp, motor cord, power cord, Nicd battery, and other parts that carry a high current. Metal and carbon chassis and other conductive parts transfer switching noise. When mounting the receiver to such a chassis, use thick double-sided tape to mount the receiver as far away from the chassis as possible. Always install a motor noise suppresser capacitor. Also, do not forget to service the brushes, and other parts. If noise causes the receiver to operate erroneously, control may be lost and an extremely dangerous situation may occur Insert the connectors firmly. If vibrations while running cause the connectors to work loose, control may be lost and an extremely dangerous situation may occur. Do not run the vehicle in the rain or through puddles or on muddy or snowy roads. If moisture enters the amp, erroneous operation may cause loss of control and an extremely dangerous situation may occur. It may also cause amp trouble. Should moisture enter and cause erroneous operation, send the MC850C out for repair and inspection. Always turn the power switches on and off in the following order: ON: Transmitter -> receiver (amp switch) OFF: Receiver (amp switch) -> transmitter If the power switches are operated in the opposite order, the vehicle may run unexpectedly and an extremely dangerous situation may occur. When going to and returning from the circuit, and when storing the model, always remove the Nicd battery. If the switch is turned on erroneously, control may be lost or a fire may start. Always perform a check of operation before running. When making adjustments, remove the motor, or place the vehicle on a stand, so that it cannot run. When not set up correctly, the vehicle may run unexpectedly and an extremely dangerous situation may occur.

Before using your MC850C, please read this manual thoroughly and use the MC850C properly and safely. After reading this manual, store it in a safe place. • No part of this manual may be reproduced in any form without prior permission. • The contents of this manual are subject to change without prior notice. • This manual has been carefully written.

The MC850C is a high-frequency drive FET speed control developed for model electric cars. It is compact and light weight competition speed control, and uses a simple digital setting system. Applicable motors (Number of turns is criteria.) Use the MC850C with a motor with 5 turns or more. *If a motor with a number of turns smaller than the above is used, the heat protector and overcurrent protection circuit may operate. The number of turns of the motor is a criteria only. Depending on the running conditions, the protection circuit may operate even if the condition above is satisfied. Power supply Nicd, NiMH battery 4~7 cells (4.8~8.4V) FEATURES • SMD MOSFETs with smallest internal resistance for minimal losses and maximum power • PWM frequency is Performed by load adaptive • The upper case made from aluminum • Heat protector • Low-voltage protection function • Power left on alarm function • External solder points with 12 AWG silicone flex wire • Terminal is Oxygen-Free-Copper • Serial communication function INSTALLATION TIPS • Mount the speed control in the model using the double-sided foam tape supplied. • Provide plenty of cooling openings in the bodywork; this increases the performance and extends the life of all lectronic components. • Install the speed control in a location where it is protected from crash damage. • The speed control should be installed in such a way that you have easy access to all connectors and the set-up button. Important: •Ensure that there is an adequate distance (approx. 3 cm) between the speed control and power cables and the receiver or receiver antenna. Avoid direct contact between all power system components and the receiver or antenna, as this can cause interference. If you encounter interference problems, re-position the components in the model. •The antenna should be run vertically up and away from the receiver. Avoid contact with any parts made of carbon fibre or metal. See also the instructions supplied with your radio control system. • Operating system: Forward and brake (resolution:255) • Power requirement: Nicd, NiMH battery 4~7 cells (4.8~8.4V) • PWM frequency: Forward：100Hz～10kHz／Initial value：2.5kHz～3.0kHz Brake：2.0kHz • BEC voltage: 6.0V (excluding at less than 6V) • Setting: One-touch input by pushbutton switch. • Current capacity (FET rating) : Forward ：840A (Momentary load: 3360A) Brake ：240A • Case size: 28.7x26.2x14.5mm (excluding protruding parts) • Silicon cord gauge size: AWG12 equivalent • Weight: 17.5g (excluding connector, cords and switch) Do not wrap your MC850C in foil. It is important to provide a free flow of cooling air over it. Do not remove the case of MC850C. The MC850C may not be repairable. Never reverse the battery polarity. Reverse connection will immediately destroy the amp. Mount the MC850C so that conductive parts do not directly touch the solder parts of the input/output cord. A short circuit may occur. If a peddle or other foreign object gets caught in the gears or the vehicle hits an obstruction, do not try to forcefully run vehicle. Forcefully running the vehicle will cause trouble. Do not touch the motor or MC850C immediately after running. Touching the motor or amp immediately after running may result in serious burns. If the motor is connected to the speed control, you must not run the motor by connecting a separate battery. This will wreck the un Turn the power switches on in the state where the vehicle is floated. When turnning on, depending on the receiver used, a motor may rotate for a moment. Be careful not to injure a finger etc. by rotation of the wheels. MOUNTING PRECAUTIONS Special Markings Pay special attention to the safety at the parts of this manual that are indicated by the following marks. Mark Meaning Procedures which may lead to a dangerous condition and cause death or serious injury to the user if not carried out properly. Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not carried out properly, or procedures where the probability of superficial injury or physical damage is high. Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or physical damage, if not carried out properly.
