[. . . ] · MOTOR CAPACITORS REQUIRED Three 0. 1µF (50V) ceramic capacitors must be properly installed on every motor to prevent radio interference. · DON'T LET TRANSISTOR TABS TOUCH Never allow the two transistor tab banks or the heat sinks to touch each other or any exposed metal, as this will create a short circuit and damage the speed control. · DISCONNECT THE BATTERIES Always disconnect the battery pack from the speed control when not in use. · TRANSMITTER ON FIRST Always turn on the power of your transmitter first so that you will have control of the radio equipment when you turn on the speed control. [. . . ] DO NOT SHORT CIRCUIT HEAT SINKS The two separate banks of transistor tabs or heat sinks should never contact each other or other conductive objects (metal, graphite, etc. ), or they will short circuit and damage the speed control. FIGURE 3 Insert each pin into the correct plug slot. Each pin should "click" into place. (Airtronics plug shown) The locking tab must not extend outside the plastic plug housing. WHT = White wire terminal (signal) BLK = Black wire terminal (negative) RED = Red wire terminal (positive) CAUTION Improper installation of these wires may cause damage to the receiver, servo, and speed control. NOVAK ELECTRONICS, INC. 18910 Teller Avenue Irvine, CA 92715 STEP 4 HOOK-UP INSTRUCTIONS Refer to set-up photo below STEP 5 TRANSMITTER ADJUSTMENT Proper transmitter adjustment is important for optimum performance from your speed control. The basic throttle channel adjustments for the transmitter are as follows: For proper ESC operation adjust transmitter as follows: 1. Set HIGH ATV or EPA to maximum setting. [Controls amount of throw from neutral to full throttle] TROUBLE-SHOOTING GUIDE This section describes possible speed control problems, causes, and solutions. 1. INSTALL MOTOR CAPACITORS Electric motors generate radio noise that can interfere with your receiver and cause radio problems. Included in the accessory kit with the speed control are three 0. 1µF (50V) non-polarized, ceramic capacitors. These capacitors muse be installed on every motor to help reduce the noise generated by the motor and also to prevent possible damage to the speed control. Solder 0. 1µF (50V) capacitors between: · POSITIVE (+) motor tab & NEGATIVE (-) motor tab. *If your motor does not have a ground tab, solder the capacitor leads to the can of the motor as shown below. Negative (-) motor tab 0. 1µF Capacitors Schottky diode Positive (+) motor tab Steering Channel Works But Motor Will Not Run · Speed control has thermally shut down­­Allow ESC to cool down­­Use milder motor or smaller pinion gear. · Make sure ESC is plugged into the throttle channel of receiver. · Possible internal damage­­Refer to Service Procedures. 2. Set LOW ATV , EPA , or ATL to maximum . [Controls amount of throw from neutral to full brakes] [Reduce this after ESC adjustment to reduce amount of brakes] 3. Set EXPONENTIAL to zero . [Controls the linearity of the throttle channel] Receiver Glitches/Throttle Stutters During Acceleration · Motor capacitors broken or missing­­Refer to Step 4. · Receiver or antenna too close to speed control, power wires, battery, or motor­­Refer to Step 3. · Excessive current to motor­­Use a milder motor or a smaller pinion gear. 4. Set THROTTLE CHANNEL TRIM to middle setting. [Adjusts the neutral position of speed control] [Increase or decrease after ESC adjustment to adjust coast brakes­­can be used to give braking in neutral trigger position] 5. Set MECHANICAL THROW ADJUSTMENT to position with 2/3 throttle and 1/3 brake throw. [Adjusts pistol-grip transmitter's throttle trigger throw] Motor and Steering Servo Do Not Work · Check wires, receiver signal harness wiring and color sequence, radio system, crystals, battery and motor connectors, and battery pack. · Possible internal damage­­Refer to Service Procedures. STEP 6 Model Runs Slowly / Slow Acceleration · Check motor and battery connectors­­Replace if needed. · Incorrect transmitter or speed control adjustment­­ Refer to Steps 5 and 6. · Optional external Schottky diode (if used) installed backwards or damaged­­Refer to Step 4. Extra 0. 1µF capacitors available in Novak kit #5620. Ground / motor can SPEED CONTROL ADJUSTMENT Before beginning this step, the speed control should be connected to the receiver and to a charged 6 or 7 cell battery pack, and the transmitter should be adjusted. [. . . ] Strip about 1/8" of insulation off both ends of the small (26 gauge) extension wires that are the correct length to reach the position that the brake light is mounted. Solder extension wires onto the brake light wires from the speed control. If two LEDs are to be used, then solder two extension wires to each brake light wire from the speed control. Solder the end of the extension wire from the black brake light wire to the lead on the notched or flat side of the LED. [. . . ]
