=== Installation ===
Fasten the controller in your model using hook-and-loop or double-sided adhesive tape. Connect the motor and receiver according to the schematic below. You may connect the motor cables in arbitrary order, as changing direction is done by exchanging any of the two cables (alternatively also by the “Direction” parameter in the configuration). Turn on the transmitter. Now you can plug in the main flight pack and turn on the speed controller with the receiver attached.
[[File:Smart PRO BEC - Installation.png|center|frameless|960x960px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' The red LED on the controller will light up for two seconds to indicate proper initialization. After the correct throttle impulse is detected (meaning off position), the controller plays a predefined melody. Now it’s ready to fly. The controller will enter standby mode on behalf of the switch or button command. The type of used switching element is defined in the controller configuration. If there is no switching element connected (keeping “Mechanical Switch” in the settings), the controller is always turned on.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=error|text='''Warning:'''
Always use brand-new, high-quality connectors and make sure that the cables are soldered perfectly. Any possibility of losing connection during a motor run represents a risk of damaging your electronics.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If you start the controller for the first time or make any significant changes in the setup, please make sure that the propeller is removed from the motor shaft.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Always disconnect batteries after the flight session ends. Even if the speed controller is turned off by the switch, it still draws some small current. This could result in a completely drained battery within a few days or weeks.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' if your flight pack voltage is greater than 25 V (6S LiPo) we recommend using the power connectors with the integrated antispark mechanism. For example, the XT90 connectors with integrated antispark can be used.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Controller mode ===
It is possible to choose from several basic controller modes:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Normal (ramped) – the preconfigured acceleration time is always applied when accelerating. This is a default mode for major use.
* Fast mode – the preconfigured acceleration is applied only when spinning up from zero revolutions. After that, a minimum possible delay is used (0.2 s for zero-to-full throttle response).
* Normal with reverse – behaves similarly to the Normal mode. In addition, you can choose a throttle reversing channel that will control the motor direction during flight.
* Heli/Governor – fast and precise control of constant RPM with many adjustable parameters.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Throttle input signal ===
The controller expects positive impulses from the receiver with a maximum refresh rate of up to 400 Hz. By default, with automatic endpoints selected, the controller will work with the vast majority of RC systems.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In this case, a minimum throttle signal pulse is loaded after start-up. The maximum power is then dynamically adjusted when you first give full throttle.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In case you need exact points on your transmitter stick, where the motor starts and where the full throttle is, you can configure manual endpoints as well.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' the controller waits for throttle-low position after startup and also every time the motor is stopped due to any error condition. If the throttle stick is not at the correct position during startup, the ESC plays a warning tone.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Motor settings ===
It is possible to configure many of the motor parameters, including acceleration, timing, motor gear ratio or number of poles. The gear ratio and number of poles are important for telemetry to measure the motor speed correctly.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Acceleration''' influences the motor response on the throttle channel. By decreasing the acceleration value, the motor response gets faster, providing a more "locked-in" feeling. However, the motor consumes more current and the controller generates more heat. We recommend the default acceleration of 1.0 s for the majority of model types, including electric gliders, scale models, EDFs etc. For 3D aerobatic flight, you might go down to 0.5 s or even less (with care). For the fastest motor response, you may also set the "Fast controller mode" in the Common Settings.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Timing''' is defined by the motor type and it is usually recommended by the motor manufacturer. It also influences the motor power and current consumption. Higher timing can increase the motor power but care must be taken not to overload the system.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Automatic timing: the timing is continuously adjusted by the internal algorithm. This is a universal solution compatible with most motor types.
* 0–10° timing: recommended for inrunners, i.e. motors with internal magnets.
* 15–20° timing: recommended for most outrunners (motors with rotating casing). It offers a good combination of power and efficiency.
* 25–30° timing: high-torque motors with many poles require the highest timing.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''The motor type''' should be modified only in some specific cases where it is necessary by the application.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
There are three options available:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* "Standard" motor type - recommended for most types and applications (default).
* "High Torque" - if you have problems with motor synchronization during fast acceleration, use this mode. '''Preconditions''': large outrunner with more than 20 poles, heavy propeller, large current peaks. We also recommend increasing the timing to more than 20°.
* "High speed" - use this mode if your drive unit exceeds 250,000 eRPM (revolutions per minute calculated for a 2-pole motor).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Startup power''' influences the first few motor revolutions. If you are not satisfied with the automatic mode, you can set the motor start to be more aggressive (positive values), or as smooth as possible (negative values).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Brake configuration ===
The electromagnetic brake is a standard feature of all ESCs used in electric glider models. '''The KAVAN Smart PRO''' controller offers several additional parameters to fine-tune the braking function. You can use one of the preconfigured brake settings or specify all the parameters as you wish.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Brake options: ====
[[File:Smart PRO ESC - Brake options.png|right|frameless|360x360px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Off: The propeller spins freely without braking.
* Soft: Transition from zero to full braking force in 1.0 s.
* Medium: Transition to full braking force in 0.7 s.
* Hard: Transition from 50% to 100% braking force in 0.5 s.
* Manual: you can specify all brake parameters manually:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Start power (start of brake) - braking force applied from the first moment of applying the brake.
# End power (end of brake) - braking force applied after the transition time elapses (usually the full braking force that stops the motor completely).
# Transition - the time between brake start power and brake end power. During this time, the braking force continuously transits from start to end power.
# Wait time - the time between unpowering the motor and applying the brake. During this time the motor spins freely without power.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Example: motor brake with the following parameters: brake start = 50%, brake end = 100%, ramp = 0.5 s, wait time = 0.3 s.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== BEC voltage and settings ===
In the Common Setting menu, you can modify the BEC voltage very precisely in steps of 0.1 V. The controller contains a very powerful BEC which can deliver up to 15 A continuous current. However, in case of a high-power setup, sufficient cooling airflow must be provided. Connecting both Telemetry and Throttle cables to the receiver is recommended to provide high current throughput.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=error|text='''Warning:''' always set the BEC voltage according to the rating of the attached electronics, including receivers, sensors and servos. Never exceed the voltage limits.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Backup battery ===
[[File:Smart PRO ESC - Backup battery.png|right|frameless|360x360px]]
In case you need a small buffer battery for covering voltage spikes of the attached servos, you can specify its presence in the Common Setting – Backup battery menu. After setting the battery type it is necessary to remove all power supplies from the controller and then reconnect them. Possible options:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* "No" (default) - the buffer battery is not present and the BEC voltage is set according to the value set in the configuration. No external power supply shall be connected to the receiver side, otherwise the BEC won’t turn on.
* "2S LiPo 8.4V" - an external power supply with a maximum voltage of 8.4 V is expected on the receiver side (see the picture). The controller won’t initialise itself if the backup battery voltage is outside the limits (or not connected). The BEC voltage will be set automatically according to the backup battery so that there is no risk of uncontrolled currents.
* "2S LiFe 7.2V" - an external power supply with a maximum voltage of 7.2 V is expected on the receiver side. The behaviour is similar to the case of 2S LiPo.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== External switch ===
[[File:Smart PRO BEC - External switch.png|right|frameless|360x360px]]
The KAVAN Smart PRO ESC allows you to install an external switch if needed. By default, the switch is not present so the speed controller/BEC turns on immediately after connecting the flight battery.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
You can specify the type of switching element in the Common Setting – Switch Type:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Mechanical (default) - the switch shorts the yellow (signal) and brown (ground) wires of the Switch/Button cable. An inverted logic is used, so that the ESC stays turned on if the switch is left open.
* Button/Hall - the first long press turns on the ESC; the second long press turns it off. The LED indicates an on/off state and blinks if the magnet (or button press) is detected. The Hall sensor can be bought as an ESC accessory.
* Electronic - allows you to install an external electronic switch (Touch Switch, RC Switch etc.). In this case, the switching device is always powered and the logic level of the signal wire specifies the on/off state to the controller.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' please pay attention to the parameters of an external switch before connecting. The signal wire uses a 3.3V logic with a weak pull-up. The power supply from the ESC is rated 10 V with a maximum current of 30 mA.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Propeller positioning ===
The positioning feature allows moving the motor/propeller to the exact position required for a safe landing, or which is just comfortable for further flying. With just a few external components (a Hall sensor and a small magnet) you can enable this feature and prevent the risk of damaging your propeller during landing. The magnet needs to be properly fixed to the rotating part (either the motor or the propeller), and the Hall sensor has to be located in the fuselage so that the magnet matches the Hall sensor at the target propeller position. After enabling the positioning feature in the menu (Prop Position = Hall Sensor), set also the Positioning PWM, so that the motor spins slowly but smoothly. You may also change the duration of the actively held motor position (Position Hold Time) which is applied after the correct position is found. The position-hold feature is useful in the case of a retractable engine since it doesn’t allow the propeller to be moved while retracting.
[[File:Smart PRO ESC - Prop position.png|center|frameless|960x960px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Connect the Hall sensor of the propeller positioning function to the '''IN-B''' port of the controller.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' use a high-quality CA or Epoxy glue to fix the magnet in the rotating part. You can also drill a small hollow in the spinner and fix the magnet in it.}}
{{Note|type=error|text='''Warning:''' do not use higher PWM than necessary otherwise the motor may overheat. Generally use as low PWM as possible so that the motor holds its position reliably. Check the current consumption using the telemetry.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Motor identification ===
Some motor brands contain an integrated temperature sensor compatible with the KAVAN Smart PRO speed controller. This sensor (T125-ID) might be used as a standalone telemetry sensor with Duplex/Hott/S.Bus2 telemetry support. Alternatively, the sensor can be directly connected to the Input port "A" of the controller (see the picture above). From this moment on, the KAVAN Smart PRO controller will know the basic motor parameters (minimum acceleration, recommended timing, gear ratio, number of poles…) and motor temperature as well. Some parameters are adjusted automatically (gear ratio, poles), and the other settings are configured after resetting the controller to factory defaults. Connect the motor-identification sensor into the IN-A port of the controller.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Active freewheeling ===
"Active freewheeling" or "Active braking" is a feature of the speed controller that reduces heat generated by the ESC during partial load operation. This mode is useful for aerobatic pilots who want not only fast acceleration but also rapid deceleration. The motor follows throttle stick input in both ways and the pilot feels more "locked-in".
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Current limiter ===
The current limiter is a part of safety controller features. It doesn’t stop the motor but rather continuously monitors the immediate current consumption and adjusts the motor power. You can enable this feature, specify the maximum allowed current and the ESC will reduce the motor power immediately as soon as the current threshold is exceeded. After the current returns back to the safe level, the motor power is restored.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Battery protection ===
The integrated battery protection is based on undervoltage detection and reducing motor power, alternatively shutting down the motor completely. You can freely set the number of cells (or leave automatic detection) and low voltage threshold per cell. Supported battery types are NiXX (1.2 V), LiFe (3.6 V max) and LiIo/LiPo (4.2 V max).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Status codes ===
The status codes are shown on the screen (JETIBOX/SMART-BOX) if any kind of error condition occurs. If any status code is set, the red LED continuously flashes.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Available status codes: ====
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Low Voltage (UL): the battery voltage got below the threshold specified in the battery protection menu and the controller either reduced the maximum power or shut down the motor completely.
* High voltage (UH): in case you use a weak battery or wall power supply, the voltage might rise above the initial level during braking. In such a case, the alarm is set and all braking functions are disabled.
* High current (IH): the current got higher than the maximum peak current defined in the product specification (120 A for KAVAN Smart PRO 85).
* High temperature (T100, T110, T120): the temperature got above the safety threshold level. The numerical value specifies the maximum detected temperature and safety protocol which has been applied.
* Commutation error (COM): a synchronization error has been detected during the motor operation. It usually occurs when the motor stops abruptly, or in case of very fast acceleration for some specific setups. This error could mean a serious issue in the motor-controller installation.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Heli/governor mode ===
[[File:Smart PRO ESC - Common setting.png|right|frameless|360x360px]]
The speed controllers contain a fast and precise governor function. You can configure the governor mode in many aspects according to your preferences.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Before enabling the governor mode, please make sure the blades are removed. In the Common Setting menu, set the Controller Mode to "Heli/Governor" and proceed through the settings below:
[[File:Smart PRO ESC - Governor.png|right|frameless|360x360px]]
[[File:Smart PRO ESC - Motor setting.png|right|frameless|426x426px]]
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Set the minimum and maximum RPM of the main rotor according to your preferences. As soon as you move the throttle away from the idle position, the controller slowly spools up until it reaches the target speed. The speed is calculated according to the throttle channel value, where low throttle corresponds to the "Minimum RPM" and high throttle corresponds to "Maximum RPM".
* Set the Spool-up Time to make the motor startups as smooth as possible. You may set the time up to 60s. The spool-up time is applied when the motor starts from zero
revolutions or if the autorotation bailout is disabled.
* Configure the Autorotation bailout time and autorotation acceleration time. The autorotation bailout function is used in case you need to quickly exit the autorotation and prevent your model from crashing. In this case, as soon as you move the throttle channel away from the idle position, the "Autorotation acceleration" will be used to spin the motor until it reaches the required speed. The "Autorotation bailout" parameter sets the time after switching off the motor, when the autorotation bailout function may be activated. After exceeding this time, a standard spool-up time will be applied.
* Advanced settings: Governor gains – (P)roportional and (I)ntegral. You may modify the gains to fine-tune the controller response to fast changes in the load during flight manoeuvres. Please perform the changes only in small steps and verify the resulting behaviour in a short test flight.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# Increase the P gain to eliminate small RPM fluctuations during straight flight, e.g. while hovering. If you hear some unexpected noise in the motor/gearbox (which means fast oscillations), reduce the P gain by 20 %.
# Increase the I gain to hold the precise revolutions during manoeuvres. If the motor speed starts oscillating noticeably, reduce the I gain by 20%.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* In the Governor mode, manual throttle endpoints are always used (by default 1.1–1.9 ms) and Active braking is enabled as well.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The picture below shows RPM response vs. throttle position. In this case, default throttle endpoints have been used (1.1–1.9ms).
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' please make sure the gear ratio and number of motor poles are correctly set in the Motor Setting menu. Also, please verify that the brake is disabled and check the state of the propeller positioning function.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Please note that dynamic changes of the motor revolutions in flight are limited by the “Acceleration” parameter configured in the Motor Setting menu. Please make sure the acceleration is slow enough so that changing revolutions in flight does not lead to sudden changes in model attitude.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Motor direction reversing ===
The motor reverse feature is available for RC systems with bidirectional bus support (EX Bus, P²Bus, SRXL2, S.Bus2). To control the motor direction you need to define an additional channel transferred through the bus system. Both cables (red and black) of the KAVAN Smart PRO speed controller must be properly linked to the receiver.
First, you need to create an additional channel on your transmitter to control the motor direction. This channel should be operated by a two-position switch.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Futaba/Spektrum: ====
[[File:Smart PRO ESC - Powerbox.png|right|frameless|419x419px]]
Use one of the AUX channels and remember the channel number. It is not necessary to use just the channels available on your receiver since the RC systems usually offer more channels over the bus than the physical number of receiver ports.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Example: If you use Spektrum NX6 and a 6-channel receiver, you may still use channel No. 7 (AUX2) to control the reversing feature over the bus.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== JETI: ====
Create a new model function in the Model - Functions Assignment menu and assign a spare two-position switch. After that, in the Model – Servo Assignment menu, assign the function to one of the receiver channels (1–16). Again, you may use the channels that are not directly available on the receiver outputs (e.g. 13–16) since they will be transferred through EX Bus without limitation.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== PowerBox: ====
Create a new model function in the Function menu by pressing the "+" button and assign it a 2-position control switch. Choose one of the available servo output channels (1–16). The switch position will be transferred over the P²Bus to the speed controller.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
To enable the motor reverse function in the controller, set the "Controller Mode" to "Normal/Reverse" and set the correct channel from the previous step. You may also play with the brake settings and reverse wait time under the "Manual" brake type.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Check the function: As soon as you flip the direction switch, the controller activates braking, and after some short pause, the motor starts spinning in the opposite direction.

KAVAN Smart PRO controllers are compatible with JETIBOX programming. The JETIBOX menu is divided into five sections:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Actual values ====
- displays the latest telemetry values together with minimums and maximums.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Available telemetry: Voltage, current, capacity, RPM, power (per cent), temperature.
* If the motor chip ID is connected, also motor identification and temperature are shown.
* Reset Min/Max - press the left and right buttons together to reset all minimums and maximums.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Common settings ====
- basic controller settings
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''Controller mode''' - basic controller mode (normal or fast).
* '''Startup beep''' - choose a melody played after the controller initialization.
* '''Standby beep''' - you can activate short repeated beeps as an indication of a powered motor drive.
* '''Motor endpoints, motor start, motor full''' - settings related to throttle input signal decoding.
* '''Capacity reset''' - you can choose at which moment the capacity and consumed energy are reset:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# '''Power on''' - the capacity is reset after the controller initialization. However, the capacity from the previous run will be displayed initially until you start the engine.
# '''Voltage change''' - the capacity is cleared after you connect a battery with a similar (or greater) voltage compared to the maximum battery voltage from the previous run. This means that each time you connect a fully charged battery of the same chemistry and number of cells, the capacity will be cleared.
# '''Manual''' - the capacity/energy is never cleared and you must perform the reset manually.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''Language''' - you can choose the language of the JETIBOX screen.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Motor settings ====
- settings related to motor parameters.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''Direction, acceleration, timing, startup power, motor type, gear ratio, motor poles''' - see the Motor Settings chapter.
* '''Brake related settings''' - see the Brake Configuration chapter.
* '''Prop position, positioning PWM, position hold time''' - see the chapter Propeller positioning.
* '''Motor Enabled (0/1)''' - motor operation can be enabled or disabled based on the logical state of the specific input “IN B.2” (connector pinout from left to right: 1 = Hall sensor input, 2 = Motor enable input, 3 = 3.3V, 4 = Ground). If you choose an “InputPin Log0/1” option, you must pull the throttle low before starting the motor. On the other hand, after choosing the "Autostart Log0/1" option, the controller will start spinning as soon as the input pin state allows it and the throttle position is above the idle position.
* '''Freewheeling''' - enables freewheeling/active braking motor operation.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Protection ====
- ESC and battery protection settings.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* '''Low battery''' - behavior when the battery is discharged. Either set to slowly reduce the motor power, or shut down the motor immediately. The minimum safe voltage is based on number of cells (cell count) and voltage per cell.
* '''Limit current''' - enable this feature to prevent high current peaks and system overload.
* '''Limit power at 100°C''' - you can edit the maximum allowed PWM after the controller temperature exceeds 100 °C. The model must be operable, but the temperature must not increase anymore.

</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== PowerBox Telemetry ====
From version 1.09, the KAVAN Smart PRO controller can recognise the PowerBox P²Bus telemetry protocol. Connect the Telemetry cable (red connector) to the P²Bus port of the receiver. The transmitter scans for attached sensors as soon as the receiver is powered up and the controller telemetry should be available within 2.5 seconds. After that, you are free to assign the telemetry to any desktop widgets and alarms. Available telemetry is similar to the Duplex EX telemetry (see above). The controller configuration through the PowerBox transmitter is not available at the moment.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Spektrum Integration ====
From version 1.06, the Spektrum telemetry support has been integrated into a special firmware version. This alternative firmware offers the SRXL2 telemetry and setting using the TextGen protocol. The KAVAN Smart PRO controller is represented in the transmitter by two telemetry devices:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* "ESC" shows battery voltage, current, BEC voltage, ESC temperature, RPM and power output.
* "Flight Pack Capacity" sensor that shows the consumed battery capacity.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Connect the Throttle cable (black connector) to the Thr (1) receiver port. For proper telemetry/setting, also connect the Telemetry cable (red connector) to the Prog/SRXL2 receiver port. The controller normally delivers only numerical telemetry. The textual menu (TextGen) is available only after a special procedure is performed during startup:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* We assume the Throttle and Telemetry cables are connected correctly and the transmitter is turned on. Now push the throttle high.
* Turn on the ESC either by connecting the flight pack or by flipping the external switch.
* The motor will beep indicating detection of the high throttle impulse. After 3 seconds, another beep announces entering the programming menu.
* Now you may pull the throttle low. On the transmitter's main screen scroll right to locate the TextGen menu. The motor will never start spinning if the textual menu is enabled. To enable normal motor operation, you have to leave the TextGen menu by choosing the "Exit" option on the first page.
* Navigation in the menu is provided by the transmitter's sticks – the elevator stick moves the cursor up/down and the aileron stick changes the selected value.
* The configuration changes are saved immediately after any value is edited.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|text='''Note:''' use the latest firmware version in your transmitter and receiver. For Spektrum NX, at least version 3.06 has to be installed. Recommended receivers: AR8360T, AR8020T, AR6610T, AR631T, AR637T…
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The KAVAN Smart PRO version 2.01 and later is compatible with Spektrum single-cable operation (Smart Throttle). To enable this function, just plug the red telemetry cable into receiver channel No.1 and keep the other (black) cable unplugged. You will be able to control throttle as well as receive telemetry. This approach is compatible with the AR10400T receiver family as well.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If you use an ESC with galvanic isolation (KAVAN Smart PRO 200/220), always turn on the ESC before the receiver. Otherwise, the telemetry functions may not work.}}

</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
=== Safety information ===
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Operate the KAVAN SMART PRO controller always in a dry environment and within the device limits stated in this guide. Never expose the device to excessive heat or cold outside the working area.
* Provide sufficient airflow to prevent controller overheating.
* Never exceed the maximum allowed operating voltage of the controller/motor.
* Do not increase the cable length between the controller and the motor. If you need to extend the wires between the controller and the battery to more than 30 cm (in total), solder multiple high-capacity Low-ESR capacitors (220–470 µF) in parallel to the power wires as close to the controller as possible. For each centimetre beyond the specified cable length, add a capacitance of 1µF for every Ampere of current passing through. For example, if you exceed the limit by 10 cm with a current of 100 A, solder a 1000 µF capacitor pack.
* Always use high-quality connectors in good condition. Replace them if any visible sign of wearing appears.
* Always remove the propeller before making any changes in the drive setup.
* Never disconnect the ESC from the battery while the motor is spinning.
* Do not remove the cover and heat sink from the device, and do not try to implement any changes or modifications. This can lead to total destruction and to the denial of any warranty claims.
* Always check the polarity of the connection. Never inverse the polarity – this could lead to total destruction.

=== PC configuration ===
It is possible to use the MAV Manager software (1.4.0 and later) to conveniently configure all controller settings, display real-time telemetry and make a backup of the configuration. The configuration menu contains four buttons in the top toolbar:
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
* Refresh - forces the configuration to be reloaded from the controller.
* Import - imports the settings from a file. If you have several speed controllers and want identical settings for all of them, simply import the same settings to each controller.
* Export - exports the settings from the controller to a file. You can easily create a backup configuration stored on your PC. After creating a backup, you may easily experiment with the controller settings and later revert back to the original configuration by pressing the "Import" button and choosing the original exported file.
* Reset default - resets the controller to factory defaults and reloads all the settings.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
