NOVAK HAVOC PRO SC - TRACK GUIDE Manual

timing indicator led
To conform to ROAR's rules for Sportsman Class racing, help race organizers monitor
driver compliance in non-timing race classes and help facilitate easier technical
inspections at races, we have included a feature in this speed control that indicates
when the ESC has its electronic motor timing advancement feature activated.
At all times when the speed control is powered ON and the Dynamic Motor Timing
is turned ON and set to a level greater than zero timing advance, the ESC's white
status LED will be illuminated during normal operation.
motor hall sensor test
The Hall Sensor Test feature in Havoc Pro SC ESC allows you to easily check
the sensors in the brushless motor that is connected to the ESC to determine
if the sensors are operating normally. This diagnostic check 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 possibly 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
The Havoc Pro SC ESC features Novak's Smart-Stop Voltage Cut-Off Circuitry
built-in, and when used properly will allow you to safely use LiPo and LiFe
batteries, without letting the cells drop below their critical safety voltage.
The default in the ESC is LiPo voltage cut-off. If using NiMH or NiCd cells,
you will need to switch this feature OFF. If using LiFe cells, you will need to
switch 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
To help you monitor your ESC's operating temperature, the Havoc Pro SC
has a built-in diagnostic feature that lets you quickly check how much head
room you have in the ESC heating department.
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.
The WHITE flashing led = normal operating temperature.
BLUE, YELLOW, GREEN or RED flashing leds = approaching thermal
shut-down of the ESC. BLUE is hot, YELLOW and GREEN are hotter, and RED
is hottest, meaning you are pushing things pretty hard and should be very
careful to avoid overheating and possible thermal shut-down.
All LEDs flashing = DANGER.....You are about to thermally shut-down.

timing esc warning
Due to the nature of timing advance speed controls, motor tolerances &
settings, vehicle performance, and track conditions, it has become virtually
impossible to provide installation and operation recommendations that
will allow you to use these speed controls and motors at their highest
performance levels without the potential for unwanted damage.
You must, use extreme caution when setting up these electronics and
carefully test your application to avoid overloading and overheating
either the speed control or the motor. These are racing electronics used
in racing conditions, and therefore damage as the result of excessive
overheating will not be covered under the product's factory warranty.
Electronic motor timing advancement can generate extrememly high speeds and
result in an uncontrollable vehicle. Use caution when operating vehicle and do not
operate around other people or in an unsafe manner to avoid injuries or damage.
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, ESC/motor damage & failure,
you must start with VERY small pinion sizes and check ESC & motor
temperatures at multiple times throughout the initial runs. 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.
temperature OVERLOAD
The Havoc Pro SC ESC has built-in ESC temperature overload protection. If the ESC starts
to overheat while timing is engaged, the speed control will turn off the Dynamic Timing
Advance feature and limit the motor power to prevent thermal overload. If the ESC's
temperature continues to rise, a second thermal-protection feature will engage. This
feature drops the speed control's power, so drivers can safely maneuver their vehicles off
of the track. If timing is not engaged, the speed control will utilize the second thermal-
protection feature only – reducing the ESC's power to a safe operating level. While this
feature can not guarantee the survival of the speed control when subjected to excessive
heat, it does provide another tool to help avoid extensive damage.
If you notice a significant decrease in performance of your brushless system during a run,
immediately check the operating temperatures of the speed control and motor. Reduce
gearing or ESC timing settings to lower operating temperatures!
