Two-State Throttle
The optional Two-State Throttle uses a two position rocker switch to adjust the requested engine speed.
Pressing the rabbit icon requests the engine to go to Run RPM. Pressing the turtle icon requests the
engine to go to Idle RPM.
Three-State Throttle
The optional Three-State Throttle uses a three position rocker switch to adjust the requested engine speed.
Pressing the rabbit icon requests the engine to go to Run RPM. The intermediate position requests the
engine to go to Intermediate RPM. Pressing the turtle icon requests the engine to go to Idle RPM.
Digital Rotary Throttle
The optional Digital Rotary Throttle uses a rotary switch to simulate the operation of a throttle potentiometer.
Like the Ramp Throttle, when first started the requested engine speed is Idle RPM. Turning the throttle knob
clockwise increases the requested engine speed. Turning the throttle knob counter-clockwise decreases the
requested engine speed.
Note
When used in combination with the Three-State Throttle, the Rotary Throttle can only be used to make
speed adjustments when the switch is in the intermediate position.
The Rotary Throttle can be used to reprogram the Idle, Intermediate and Run RPMs when used in
combination with the Ramp Throttle or Three-State Throttle. After adjusting the engine to the desired
speed with the throttle knob, press and hold the knob and then press and hold the throttle switch
position to be changed. After two seconds the current speed has been stored, the knob and switch can
now be released.
