Programmable functions of the KAVAN ESC

Brake: ON/OFF

ON: Sets the propeller to the brake position when the throttle stick is at the minimum position (Recommended for folding props).
OFF: Sets the propeller to freewheel when the throttle stick is at the minimum position.

Battery type: LiPo or NiCd/NiMh

Low Voltage Cut-off Type: Reduce Power/Hard Cut-off

Reduce Power: ESC reduces motor power when the preset Low Voltage Protection Threshold value is reached.
Hard Cut-off: ESC instantly cuts motor power off when the preset Low Voltage Protection Threshold value is reached

Low Voltage Protection Threshold: (Low/Medium/High)

For Li-xx packs: the battery cell number is calculated automatically. The Low/Middle/High cut-off voltage for each cell is 2.85/3.15/3.3 V. For example: For a 3S Lipo, when the "Middle" cut-off threshold is set, the cut-off voltage will be 3.15×3=9.45 V.
For Ni-xx packs: Low/Middle/High cut-off voltages are 0/50/65 % of the startup voltage (i.e. the initial voltage of the battery pack), and 0 % means the low voltage cut-off function is disabled. For example: For a 6-cell NiMH battery, the fully charged voltage is 1.44×6=8.64 V, when the "Middle" cut-off threshold is set, the cut-off voltage will be: 8.64×50%=4.32 V.

Soft Acceleration Startup: Normal/Soft/Very Soft

Normal mode is suitable for fixed-wing aircraft. Soft or Very Soft modes are suitable for helicopters. The initial acceleration of the Soft and Very Soft modes is slower, it takes 1.5 seconds for Soft startup or 3 seconds for Very Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re-startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.

Timing setup: Low / Middle / High

Low (3.75°) – Setting for most 2 pole motors.
Middle (15°) - setting for motors with 6 or more poles.
High (26.25°) - setting for motors with 12 or more poles, outrunners

In most cases, middle or low timing works well for all types of motors. However, for high efficiency, we recommend the Low timing setting for 2 pole motors (generally, in-runners) and middle timing for 6 poles and above (generally all outrunners). For higher speeds, High timing can be set. Some motors require different timing setups therefore we suggest you follow the manufacturer-recommended setup.

Note: run your motor on the ground first after making any changes to your motor timing.

Music/LiPo Cells

Not used.

Option

Reserve. Not used.

Wiring sequence

Disconnect the main battery pack from the ESC
For the KAVAN ESC (with a built-in BEC), please disconnect the Rx cable (trio wires) of the ESC from your receiver, and then connect it to the program card at the top right corner position marked with “BEC”.
Connect the main battery pack to the ESC
The LEDs on the program card will light to show the current programmable values of the ESC.

Note: The sequence of Step 2 and Step 3 cannot be reversed! Otherwise, the program card cannot work properly.

Caution: Don’t use a battery pack with a voltage higher than 6 V to supply the program card!

Operation

Click the Up/Down ⯅/⯆ button to select the programmable item, the corresponding LED will blink. Then click the Left/right ⯇/⯈ button to select the options for this item. The flashing LED shows the value you are just selecting. Finally, click the "OK" button and the blue LED "Connecting" will blink, which means the new settings are being transmitted to the ESC. When the data transmission is finished, the blue LED stops blinking. That means the new settings are accepted and stored in the ESC.

Safety precautions

Do not install the propeller (fixed wing) or drive pinion (helicopter) on the motor when you test the ESC and motor for the first time to verify the correct settings on your radio. Only install your propeller (plane) or pinion (heli) after you have confirmed that the settings on your radio are correct.
Never use ruptured or punctured battery cells.
Never short circuit battery or motor terminals.
Always use proper insulation material for cable insulation.
Always use proper cable connectors.
Wrong battery polarity will damage the Card and ESC and void the warranty.
Use only batteries that are supported by the Card and ESC and ensure the correct polarity before connecting.
Handle your model with extreme care once the battery pack is connected and keep away from the propeller at all times. Never stand in line or directly in front of any rotating parts.
Do not immerse the Card under water, do not allow it to get wet while powered up.

Recycling and waste disposal note (European Union)

Electrical equipment marked with the crossed-out waste bin symbol must not be discarded in the domestic waste; it should be disposed of via the appropriate specialised disposal system. In the countries of the EU (European Union) electrical devices must not be discarded via the normal domestic waste system (WEEE - Waste of Electrical and Electronic Equipment, Directive 2012/19/EU). You can take your unwanted equipment to your nearest public collection point or recycling centre, where it will be disposed of in the proper manner at no charge to you. By disposing of your old equipment in a responsible manner you make an important contribution to the safeguarding of the environment.

EU declaration of conformity (European Union)

Hereby, KAVAN Europe s.r.o. declares that the KAVAN Programming Card is in compliance with the essential requirements as laid down in the EU directive(s) concerning electromagnetic compatibility. The full text of the EU Declaration of Conformity is available at http://www.kavanrc.com/doc/.
