motor hall sensor test
The Hall Sensor Test diagnostic feature in this ESC allows you to easily check the sensors in the brushless motor connected to it to determine if they are operating normally. This will help you pinpoint the cause of problems in your system, and hopefully reduce the down time and expenses associated with sending your product in for service when you can resolve the issue yourself.
To access this feature, simply follow these steps:
1.Follow the steps in the ‘CUSTOM PROGRAMMING OPTIONS’ section to access the Hall Sensor Test option via the ESC’s SET button.
2.Slowly rotate the motor’s output/pinion shaft. If motor is installed in a vehicle, slowly rotate the drive train so that the motor also rotates.
3.The status LEDs on the speed control should cycle through illuminating the BLUE, YELLOW, and RED status LEDs.
If the BLUE, YELLOW, and RED LEDs light up one after another as the motor’s shaft is rotated, the Hall Sensors in the motor are operating normally.
If any one of the BLUE, YELLOW, or RED status LEDs do not light while rotating the motor’s shaft, there is a either a problem with the Sensor Harness Cable (or its connections either at the motor end or the ESC end) or with the actual Hall Effect Sensors in the motor’s timing section.
If your motor has a user-replaceable double-ended sensor harness, replace it with another one to determine if this is this source of the problem. If, after replacing the harness, all three of the LEDs still do not light up, it would appear that one of the sensors inside the motor has been damaged--replace the timing section of your motor, or if your motor is not user-rebuildable, send it in the manufacturer for the appropriate service.
voltage cut-off circuitry
This speed control features Novak’s Smart-Stop Voltage Cut-Off Circuitry built-in, and when used properly will allow you to safely use LiPo and LiFe type batteries, without letting the cells drop below their critical safety voltage during operation.
The default setting in the speed control is that the Voltage Cut-Off is turned ON and is set to LiPo. If you are using NiMH or NiCd cells, you will need to switch the Voltage Cut-Off feature OFF. If you are using LiFe cells, you will need to switch the Voltage Cut-Off feature to the LiFe battery setting.
Note: Whenever the speed control’s One-Touch Programming is performed, this setting will revert to the LiPo default setting.
DO NOT USE LiPo/LiFe BATTERIES WITH
VOLTAGE CUT-OFF TURNED OFF
temperature monitoring
This ESC has a built-in diagnostic temperature monitoring feature that lets you quickly check the ESC’s operating temperature at any time.
While connected to a battery and powered ON, simply tap the ESC’s SET button and one of the on-board LED lights will flash 4 times to indicate the operating temperature of the speed control.
WHITE flashing LED = normal operating temp--under 135°F (57°C). BLUE flashing LED = medium operating temp--136-147°F (58-64°C). YELLOW flashing LED = hot operating temp--148-167°F (65-75°C).
GREEN flashing LED = hotter operating temp--168-194°F (76-90°C).
RED flashing LED = hottest operating temp--195-215°F (91-102°C).
You are now pushing the ESC extremely hard and should be very careful to avoid overheating and possible thermal shut-down.
All LEDs flashing = DANGEROUS operating temp--216-239°F (103-115°C). Your ESC is now about to thermally shut-down.
Reduce the pinion size to avoid overheating speed control that could result in potential damage.

one-touch programming
With the ESC connected to (at least) a charged battery pack, the receiver, and the brushless motor’s sensor harness:
1.TURN ON THE TRANSMITTER’S POWER
2.PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3.TURN ON THE SPEED CONTROL’S POWER
With transmitter throttle at neutral, and still pressing the SET button, slide the ESC’s ON/OFF switch to ON position.
4.CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5.RELEASE SET BUTTON AS SOON AS RED LED TURNS ON
6.PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until the green status LED turns solid green.
Note: Motor will not run during programming even if connected.
7.PUSH TRANSMITTER THROTTLE TO FULL-BRAKE/REVERSE
Hold it there until the green status LED blinks green.
8.RETURN TRANSMITTER THROTTLE TO NEUTRAL
The red status LED will turn solid red, indicating that the ESC is at neutral and that proper programming has been completed. Blue & yellow LEDs will also be on indicating Minimum Brake (blue) & Drag Brake (yellow) settings are at levels above 0%.
If transmitter settings are changed, the One-Touch Programming must be repeated. If you experience any problems, turn off ESC and repeat One-Touch.
NOTE: Whenever the One-Touch Programming set-up is performed, the speed control will automatically revert back to the factory-default settings.
proper gear selection
Motor operating temperature is the ONLY way to properly set vehicle gearing
The Motor and Speed Control should not exceed 160°F MAX at any time during run!
Change the gearing to avoid overheating!
DO NOT FREE-REV MOTOR!
Free-running your brushless motor in a no-load condition can cause rotor failure & ESC transistor damage that will not be covered by the product’s warranty.
Because of the potential danger of overheating and ESC/motor damage and failure, you must start with VERY small pinion sizes and check the speed control and motor operating temperatures at multiple times throughout the initial runs after installation. This is the only way to ensure that you are not causing excessive heating.
If ESC & motor temperatures remain low & stable, you can slowly increase the pinion size while again monitoring the temperatures to determine the safe gearing for your vehicle, motor, and climate/track conditions. Because these variables can change or be modified, you MUST continually monitor ESC & motor temperatures to protect your electronics from damage.
transmitter adjustments
Transmitter adjustments may not be required to properly complete the One-Touch programming of the speed control. However, should you have any problems completing the ONE-TOUCH PROGRAMMING, adjust the settings on your transmitter as listed below, then repeat the ONETOUCH PROGRAMMING as described above.
THROTTLE CHANNEL ADJUSTMENTS
A.Set HIGH ATV or EPA to 100%. [amount of throw at full throttle]
B.Set LOW ATV, EPA, or ATL to 100%. [amount of throw at full brakes]
C.Set EXPONENTIAL to zero setting. [throttle channel linearity]
D.Set THROTTLE CHANNEL REV. SWITCH to either position.
E.Set THROTTLE CHANNEL TRIM to middle setting.
[adjusts neutral position/increases or decreases coast brakes]
F.Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 70% throttle and
30% brake throw (or 7:3)–best for racing ESCs. Set to 50% throttle and 50% brake for full time use with reverse to get the best performance in reverse.
[adjusts trigger throw on electronic/digital pistol-grip transmitters]
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]
•NOT ALL TRANSMITTERS HAVE ALL OF THESE ADJUSTMENTS•
Good Quality Radio System Suggested
With the higher performance of brushless systems, undesirable radio system noise may occur when used with lower quality radio systems. 2.4GHz radio systems are the best to use. FM radio systems are acceptable, as long as the system is high quality. AM radio systems are not recommended.
