User manual FUTABA MC850C

[. . . ] · This manual has been carefully written. 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. [. . . ] 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. Serial communication function (Options) The following settings and operations are possible with a Windows PC by using the optional interface unit (CIU-2). · Data logging function data read and erase (Data logging memorizes the running current and power supply voltage for approximately 8 minutes at 1 second intervals. ) · Variable frequency range setting: 100Hz ~ 10kHz (Sets the load response system variable frequency range. ) Dead band: ±2µs ~ ±55µs (The neutral point range can be set. ) · Low battery protection voltage setting: 2. 5V ~ 6. 0V (Sets thevoltage which cuts output to motor when the power supply voltage is drops. ) · Current limiter: 50A ~ 300A, cancel (The current limit for suppressing wasted power can also be set and turned OFF. ) · Brake MAX duty: 0% ~ 100% (Sets the brake strength of the MAX brake point from neutral. ) · Neutral brake: 0% ~ 100% (Brake setting at the throttle neutral point) *Windows is registered trademark of Microsoft Corporation. Symbol: :Prohibited :Mandatory 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. 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 white ring must always face the positive side. N · Full brake state · Press SET button once. flashes green three times and the motor beeps. LED goes out · This completes the set-up procedure. LED DISPLAY The MC850C operating state can be checked with the LED as shown below. (Amp power left on alarm) Operation Brake MAX point [INSTALLATION] See the pictures for the example of installation. Brake Neutral point Foward High point When the transmitter power was turned off first. 1 Remove the terminal cover from the MC850C. 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. [. . . ]
