User manual NOVAK GT7 PROGRAMMABLE RACING ESC

[. . . ] INSTRUCTION MANUAL Part #1785 STEP 1 GT7 BASIC SET-UP CHANGING INPUT HARNESS STEP 2 GT7 BASIC SET-UP MOUNTING INSTRUCTIONS PROGRAMMABLE RACING ESC The GT7 speed control comes with the industry standard connector on a user-replaceable input harness. However, with some older style receivers, the wiring sequence in the plastic connector must be changed. This is an important step, because the receiver electronics may be damaged if the sequence is incorrect. 1. DETERMINE BEST ESC MOUNTING LOCATION Choose a mounting position that keeps power wires away from the receiver and antenna, and will provide maximum airflow around case to allow for proper cooling. [. . . ] CONNECT SPEED CONTROL TO RECEIVER Configure input harness wires and connect ESC to the THROTTLE CHANNEL of receiver as described in Step 1. User-replaceable input signal harness Use connectors that can not be connected backwards!It is good practice to use female connectors on battery packs to avoid shorting the connector and the battery. If using connectors for both battery & motor: Use a male connector on the ESC wires going to the battery and a female connector on the wires going to the motor. This will help prevent cross connection of the battery and motor outputs that would cause internal damage to the ESC. For additional information on using connectors, please visit our website. Trail excess wire off top of antenna mast Three 0. 1µF (50V) ceramic capacitors Blue power wire (motor negative) (+) (+) Schottky diode (­) MOTOR CAPACITORS [#5620] Additional motor capacitors are available in Novak kit #5620. BATTERY/MOTOR 14G POWER WIRE [#5500 & 5505] Replacement GT7 power wire is available in Novak kits #5500 (36"red & 36"black) & #5505 (36"red & 36"blue). INPUT SIGNAL HARNESS [#5315 & 5320] The user-replaceable input signal harness is available in both short (4. 5") and long (9. 0") lengths to fit different applications. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 70% throttle and 30% brake throw (or 7:3). [adjusts trigger throw electronic/digital pistol-grip transmitters] Selecting Minimum Brake %--TRANSMITTER ON With transmitter ON & GT7 connected to receiver and battery: 1. PRESS & HOLD SPEED CONTROL'S SET BUTTON With transmitter throttle at neutral, press and hold SET button on GT7 until all 4 LEDs turn on. PUSH TRANSMITTER THROTTLE TO FULL-BRAKES When the transmitter's throttle is moved to the full-brake position while still pressing SET button on the GT7, only the blue status LED will remain on (2nd LED from top). The number of times the LED flashes indicates the Minimum Brake selection (1 of 7). PRESS & RELEASE SET BUTTON TO CHANGE SELECTION Each press will change to the next consecutive Minimum Brake value. WAIT FOR SPEED CONTROL TO EXIT PROGRAMMING When SET button is not pressed for about 3 seconds, the selected Minimum Brake value is loaded into memory. The blue status LED will then flash a few times rapidly, then the status LEDs will come on, one at a time, scrolling from topto-bottom indicating that you are exiting programming. The red status LED will then turn on solid, indicating that the speed control is at neutral and ready to go. G. Set MECHANICAL TRIGGER THROW ADJUSTMENT to position with 2/3 throttle and 1/3 brake throw. [adjusts trigger throw on mechanical/analog pistol-grip transmitters] RECEIVER BATTERY PACK If using an external receiver battery pack with the GT7: 1. Plug an external 5 cell (1. 2VDC/cell) receiver battery pack into the battery slot of the receiver. Use receiver battery pack's ON/OFF switch to turn the system power on and off­­Do not use the GT7's switch. Checking That Transmitter Has Adequate Throw With transmitter ON, GT7 OFF & connected to receiver & battery: 1. RELEASE SPEED CONTROL'S SET BUTTON Once yellow, blue, & red LEDs (top 2 LEDs + bottom LED) turn on, release the GT7's SET button. PULL TRANSMITTER THROTTLE IN DRIVE DIRECTION Slowly pull throttle toward full drive­­blue LED blinks until 500µS of throw is reached then it turns solid. (adjust throw in Step A above) TROUBLE-SHOOTING GUIDE This section describes possible ESC problems, causes, and solutions. 6. PUSH TRANSMITTER THROTTLE IN BRAKE DIRECTION Slowly push throttle toward full brake­­yellow LED blinks until 200µS of throw is reached then it turns solid. (adjust throw in Step B above) Note: Without transmitter adjustments mentioned in Step A & B, ESC will still program & operate normally with a minimum of ±90µS of throw. Steering Channel Works But Motor Will Not Run · Check motor connections. · Make sure input signal harness is plugged into throttle channel of receiver and the ESC. · Possible internal damage­­Refer to Service Procedures. Receiver Glitches/Throttle Stutters During Acceleration · Receiver or antenna too close to speed control, power wires, battery, or motor­­Refer to Step 2. · Excessive motor current­­Use milder motor or smaller pinion gear. [. . . ] LEDs SCROLL UP & DOWN, THEN PROGRAMMING LOOP STARTS OVER AT SELECT DRIVE PROFILE Pressing SET button during LED scroll lets you exit the customizing mode. If you do not press the SET button, the programming loop will repeat itself 3 more times, before exiting the customizing mode by itself. 5 oval 6 4-cell POSSIBLE slick APPLICATION tracks smooth aggr. modif. Each Throttle Program is comprised of 3 parameters: · Drive Profile--Drive PWM Frequency, Minimum Drive, & #drive steps. · Minimum Brake Percentage--1 of 7 settings from 20 to 55%.
