INTRODUCTION When designing an electronic speed control, the Novak engineers are put to the task of setting design parameters such as how wide the Deadband should be, what percentage of Full Drive should be applied with the first pulse of transmitter information, or what Brake and Drive Frequencies to use. In the past, our engineers would determine the best possible compromise for these parameters based on different vehicles and driving styles.
ABOUT THE PIT WIZARD 2 Line/16 Character LCD displays menu position and options for easy navigation. Novak’s exclusive ESC Profile Software allows you to modify the design parameters of your Cyclone and store ten different racing Profiles. {MODE} button takes you through the available main menu selections. {UP} & {DOWN} buttons let you scroll thru the main menu sub-screens and the user-adjustable parameter values.
ADJUSTABLE PARAMETERS The Pit Wizard’s Profile Software accesses the Cyclone speed control’s previously hidden fourth Profile. The user-programmable fourth Profile gives you the ability to customize several design parameters of the speed control. This adjustability will allow you to custom tailor the speed control’s response and feel to your preference for different applications.

ADJUSTABLE PARAMETERS (CONT.) • BRAKE PWM FREQUENCY 50 BRAKE PWM FREQUENCY 50 20 20 10 TRIGGER Full Brake POSITION Neutral 10 % FULL DRIVE 100 100 DEADBAND % FULL BRAKE –Measured in Hertz (Hz). –Frequency at which the duty cycle information is being sent from speed control to motor for braking. –Brake PWM Frequency controls deceleration characteristics of your vehicle with respect to trigger movement in the Full Brake direction (Figure 5).
ADJUSTABLE PARAMETERS (CONT.) • DRAG BRAKE VALUE 50 30 50 Drag Brake Value [30%] 20 10 20 TRIGGER POSITION 10 % FULL DRIVE 100 100 DEADBAND % FULL BRAKE –Measured as percentage (%) of Full Brake value. –Adjusts amount of Drag Brake applied within the Deadband when throttle trigger is in the Neutral position (Figure 6). –When the Drag Brake value is greater than zero, Drag Braking is applied in the Deadband area.
ADJUSTABLE PARAMETERS (CONT.) • DRAG BRAKE TOGGLE 50 50 30 10 TRIGGER POSITION 10 % FULL DRIVE 100 100 DEADBAND % FULL BRAKE –Switches Brake Pot of the Cyclone ESC from Minimum Brake adjustment to Drag Brake Value & Minimum Brake adjustment. –When Drag Brake Toggle is ON, Drag Braking is applied in the Neutral/Deadband area at the same frequency as Brake PWM Frequency is set (Figure 7). When the trigger is returned to the Neutral position, braking information is sent to the motor.
ADJUSTABLE PARAMETERS (CONT.) • DRAG BRAKE FREQUENCY 50 DRAG BRAKE FREQUENCY 50 20 20 10 TRIGGER Full Brake POSITION Neutral 10 % FULL DRIVE 100 100 DEADBAND % FULL BRAKE –Measured in Hertz (Hz). –Frequency at which duty cycle information is being sent from Cyclone to motor for Drag Braking during Neutral/Deadband. –The Drag Brake Frequency (Figure 9) controls deceleration characteristics of vehicle with Drag Brake during Neutral/ Deadband.
HARDWARE CONNECTION 1. Install four (4) 1.5 volt LR6 (AA) Batteries –Remove the two (2) screws from bottom edge of the top-side of Pit Wizard case with a number 1 Phillips screwdriver, turn the unit over and remove the two (2) remaining Phillips-head screws that secure the lower portion of the case bottom. –Insert four (4) 1.5 volt LR6 (AA) batteries (Not included) into the battery box––Cell orientation is illustrated in battery box.
PRECAUTIONS In addition to using basic common sense, please take special note of the following precautions: • Water and electronics DO NOT mix. • DO NOT allow solvents to come in contact with the Pit Wizard to avoid damage to the case and electronics. • DO NOT allow connector pins on D•LINK harness to contact transistor tabs or heat sinks on speed control. • DO NOT touch connector pins on D•LINK harness to avoid static electricity damage to the electronics.
MONITORING TRANSMITTER TRIGGER This function allows you to monitor the values of your transmitter’s positions for Neutral, Full Brake, and Full Throttle (measured in µS). This is used to determine if your transmitter has the proper amount of throw that is needed by your Cyclone speed control. 1. Turn on your transmitter, then turn on your speed control. 2. Turn on the Pit Wizard’s power switch––Slide to ON position. The display will show the start-up screen as shown on page 15. 3.
UPLOADING PARAMETERS FROM CYCLONE The following steps will allow you to upload the Parameters from the Cyclone speed control. The values for the Profile (1, 2, 3, or 4) that is currently active in the Cyclone will be uploaded. You must upload the values for Neutral, Full Throttle, and Full Brake that are stored in your Cyclone’s One-Touch memory, otherwise new/incorrect settings will be downloaded with any new Profile. 1. Turn on your transmitter, then turn on your speed control.
