IN FCSwitch4

The AT FCSwitch4 is a device that provides a maximum level of safety to the operation of the quadcopters, allowing redundancy in the most critical component: the flight controller.

 

The FCSwitch4 changes the motor outputs of two redundant flight controllers in a smooth and controllable manner. By using a PWM signal from any free RC channel, the pilot can change at any time between two flight controllers. The patented algorithm allows a smooth and safe transition, while responding to the pilot's inputs at any time.

 

Since the FCSwitch4 is completely independent of the two flight controllers, it is not affected by firmware errors, GPS blocking or sensor malfunction. In case of departure or any strange behavior of the active flight controller, the pilot switches to the second flight controller, immediately regaining control of the quadcopter.

 
SPECIFICATIONS

Dimensions: 53 x 21 x 17 mm (LxWxH)

Weight: 13 grams (25 grams with the supplied cables)

Power: + 5V.

 
 
ELECTRIC CONNECTION


The ATFCS4 is fed to 5 V through a servo connector at the power input, using the standard servo polarity (medium pin + 5 V, FLOOR FLOOR lower).
 
FC1 INPUT CONNECTIONS


The four outputs of the flight controller 1 engine are connected (only the PWM signal pins) to the bottom line of the input connector, as shown in the diagram.


FC2 INPUT CONNECTIONS


The four outputs of the flight controller 2 engine are connected (only the PWM signal pins) to the top line of the input connector, as shown in the diagram.

PWM SIGNAL CONTROL


To select which flight controller is active, we must connect the CONTROL input to any spare channel of the RC receiver (it is not necessary to connect the power, only the PWM signal and the ground connection are needed). When the received PWM signal has a pulse duration shorter than 1600us, flight controller 1 is active. When the PWM signal is longer than 1600us, flight controller 2 is active.

 
OUTPUT CONNECTIONS


The output signals of the PWM motor are connected to the four ESCs as shown in the diagram.

Depending on the used flight controller, the numbering of the motors may not coincide with the FC1 / 2 inputs, but each ESC output will be connected to the corresponding number of FC1 or FC2 inputs. This means that if Motor 1 of the output of Flight Controller 1 is connected, for example, to FC1 / M4, then the ESC corresponding to Motor 1 must be connected to ESC / M4.

IMPORTANT

The central pins of the ESC outputs are connected to the + 5V internal power bus. If the ESCs supply power through their center cable, this cable must be cut to avoid shortening the + 5V supply supplied to the ATFCS4 to the internal power supply ESC. If the ESCs used must receive external power (normally Opto ESC), then the center cable must be connected.

LED INDICATORS

The ATFCS4 includes 4 LEDs, with the following assignment:

    ON LED (red): the device is powered at + 5V.
    SIGNAL LED (green): a valid PWM signal is received through the CONTROL input.
    FC1 LED (blue): Flight controller 1 is active and controls the ESC outputs.
    FC2 LED (orange): Flight controller 2 is active and controls the ESC outputs.

 
CONFIGURATION TIPS

The two flight controllers must be connected in parallel to the RC receiver. The easiest way is to use a single PPM signal and connect the PPM output of the RC receiver to the PPM input of both flight controllers using a Y-type servo cable.

It is recommended to perform a ground test, verifying that, with both controllers, the balancing, tilt and orientation behave correctly, to confirm that the ESCs are connected in the correct order to the outputs of the flight controllers through the ATFCS4 .

 
In case of using two totally different flight controllers, with different armed procedures, make sure that both controllers are armed, perform both arming procedures and switch between both flight controllers with the motors at low RPM to confirm that both are armed.
