User manual FUTABA MC800C

[. . . ] It is compact and light weight competition speed control, and uses a simple digital setting system. OPERATING PRECAUTIONS 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. Should moisture enter and cause erroneous operation, send the MC800C Ver. 2 out for repair and inspection. Applicable motors (Number of turns is criteria. ) Use the MC800C Ver. 2 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) 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 MC800C Ver. 2 immediately after running. Touching the motor or amp immediately after running may result in serious burns. 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. If the motor is connected to the speed control, you must not run the motor by connecting a separate battery. This will wreck the unit. DESCRIPTION OF FEATURES · SMD MOSFETs with smallest internal resistance for minimal losses and maximum power · Digital variable modes "Power Control 2", "Hyper Brake" and "Neutral Brake" MC800C Ver. 2 features three different modes which enable you to adjust motor power and the driving "feel" to match your special requirements precisely. [. . . ] Avoid contact with any parts made of carbon fibre or metal. See also the instructions supplied with your radio control system. CONNECTION Red-positive (+B) battery INSTALLATION Black-negative (-B) battery ·Solder the suppressor capacitors and the Schottky diode to the motor. Motors with no suppressor capacitors, or 1 3 2 inadequate suppression, may cause the MC800C Ver. 2 to malfunction. Always solder the capacitors supplied to your motor. The schottky diode improves the efficiency of the speed control / motor combination and provides extra protection to the brake FETs. The Schottky diode white ring must always face the positive side. ·Remove the motor pinion, or ensure in some other way that the wheels of the model can rotate freely. ·Install the MC800C Ver. 2 in the model. ·Connect the MC800C Ver. 2 to the receiver (throttle channel). ·Connect the MC800C Ver. 2 to the motor: red wire to positive (+), blue wire to negative (-). ·Check all the wiring and connections before you connect the MC800C Ver. 2 to a drive battery. Caution: incorrect polarity will wreck your MC800C Ver. 2. The MC800C Ver. 2 is now ready to be set-up (see back page). Accessories: · Miniature screwdriver (Use to press the pushbutton switch. ) · Schottky diode (for motor) · Capacitors (for motor) · Double sided tape · Others [MC800C Ver. 2 Technical Data] (Specifications are subject to change without prior notice. ) Red-positive (+M) motor Blue-negative (-M) motor Terminal cover MODE Pushbutton switch MODE LED SET Pushbutton switch SET LED MC800C Ver. 2 Power switch Receiver connector Connects to the receiver throttle channel. · Operating system: Forward and brake · Power requirement: Nicd, NiMH battery 4~7 cells (4. 8~8. 4V) · PWM frequency: 3. 1kHz (Especially Power Control level 4 is performed by load adaptive. ) · Setting: One-touch input by pushbutton switch. · Current capacity (Momentary load): 235A (FET rating) · Case size: 28. 3x25. 4x14. 4mm (excluding protruding parts) · Silicon cord gauge size: AWG12 equivalent · Weight: 17. 5g (excluding connector, cords and switch) · BEC voltage: 5. 8V (excluding at 4 cells) SET UP Neutral, high, and brake MAX points setting In set-up mode MC800C Ver. 2 stores every step when you press the Set-up button. All the settings are stored in the unit even when the speed control is subsequently disconnected from the battery. Set up the following basic functions on your transmitter (if present): · High ATV, EPA (throttle travel) - maximum · Low ATV, EPA, ATL (brake travel) - maximum · EXP, EXPO (exponential) - start with 0 · SUB trim (neutral trim) - center · TH trim - center · Throttle reverse (servo reverse) - any setting; must not be changed after completion of set-up procedure. · Asymmetrical stick travel is possible (2/3 throttle - 1/3 brake) If your transmitter does not feature these set-up functions, it is already in "basic set-up" mode. Remove the motor pinion, or ensure in some other way that the wheels of the model are free to rotate. START ACCELERATION FUNCTION Start Acceleration function setting · Activate Start Acceleration by holding transmitter at full brake for 5 sec before start. This system shortens the speed control's response time at start time, with the result that you have more acceleration available. CHECKER LED DISPLAY Relationship between amp operation and checker LED display The MC800C Ver. 2 operating state can be checked with the checker LED as shown below. Operation High point Forward Checker LED display On (green) On (green) *Becomes brighter nearer the high point.
