Mode Control

Six Position Switch

(Refer here for description of the 6 position switch.)

The six position switch S3 selects one of six modes. Curve CV1 converts the S3 values to the channel values required to select the correct mode in the autopilot. Channel 8 is used to set the mode.

On the Mixer screen, the following line configures channel eight.

0.3 (Delay Up)

Mode

 

A delay up of 0.3 seconds is used so that the switch can move across modes quickly without implementing the selected mode until the switch is in position for at least 0.3 second.

Curve CV1 creates a PWM signal for each desired flight mode that falls in the middle of each of the flight mode ranges. This table maps the S3 switch values to the flight mode values.

Geofence Control

On the Taranis radio, switch SC is used to control the geofence as follows.

Switch SC↑ is geofence off.

Switch SC- is geofence enabled.

Switch SC↓ is geofence enabled and reset.

Geofence Enable

The geofence enable channel in the Taranis is channel 7.

When channel 7 = -100%, the geofence is disabled. When channel 7 = 0 or +100%, the geofence is enabled.

 

The mixer controls channel 7 as follows.

Receiver Failsafe

The receiver must show the flight controller when the receiver has lost signal from the transmitter so that the flight controller can then carry out its fail safe procedure.

Preflight Checks

When the Taranis starts, it checks that the throttle, switches and pots are in the required positions.

At startup, the following conditions are set.

- throttle down

- mode switch SA in the mid position (not AUTO or RTL mode)

- 6 position switch in MANUAL
