Engine Control
Redundancy (Back-up) throttle control
If the throttle control does not operate due to a controller defect, press the redundancy switch. Throttle control is then taken
over by the manual throttle buttons.
When pressing a redundancy switch, control power supply to the controller is turned
OFF
, and the manual throttle circuit is
activated. There is a signal of
5V
on the motor driver side. When pressing manual throttle, instruction of a rotational direction is
sent to a motor driver, same method as in previous section Controller rotational instructions.
To stop engine, manual throttle is pressed
DOWN
, or the key switch is turned
OFF
.
While running the engine, if the redundancy switch is turned
OFF
(normal status), the engine stops so that the
0
position of
throttle motor is detected.
