User manual FUTABA MC850C

[. . . ] Please write to Futaba if you feel that any corrections or clarifications should be made. 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. [. . . ] · 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. See also the instructions supplied with your radio control system. CONNECTION Negative (-B) battery SET UP In set-up mode MC850C 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. Terminal cover Negative (-M) motor Pushbutton switch LED Silicone flex wireBlack Positive (+B) battery (+M) motor Silicone flex wire Blue Silicone flex wire Red 1 Turn on the power in following order. · Switch the transmitter on. · Set the transmitter throttle stick to neutral, and then switch the speed control on. · Depending on the neutral position of the throttle stick, the red and green LED will blink simultaneously (orange) and a beeping sound will be repeated. (Alarm: Waiting for neutral data) Power switch [Wiring Precautions] · Always set the MC850C power switch to the OFF position before performing any wiring. · When stripping the covering of the silicon cord to the length needed for soldering, be sure not to cut the center conductor with the cutter or nippers. · Refer to the diagram above and check the polarity before performing wiring. (The 3 colors, red, blue, and black, of the silicon cord indicate the polarity. ) · When soldering to the terminals of the MC850C, remove the terminal cover. [. . . ] 2 Use the included heat shrink tube to isolate the pins of the Power Capacitor. The protection circuit is automatically reset by a drop in the FET temperature. Low battery protection: When the power supply voltage drops, the output current to the motor is limited and supply voltage to the receiver is ensured. [. . . ]
