1. Calibrate the tachometer by selecting Calibrate Tach.
a) With the engine at idle, measure the RPM using a photo-tachometer or handheld tachometer. Better
RPM accuracy is achieved if the engine is allowed to warm up.
b) Enter the measured RPM into the panel while the engine is still running at the measured RPM.
2. Mount the Actuator.
a) Select the Actuator Setup menu and then Mounting and Setup.
b) The actuator can now be physically mounted to the engine. The display buttons can be used to
Extend or Retract the actuator as needed to ensure full travel of the throttle arm.
3. Use the Extend or Retract controls to adjust the throttle arm to its Minimum point and select Set Min
Travel Point on the panel. The engine does not need to be running.
4. Use the Extend or Retract controls to adjust the throttle arm to its Maximum point and select Set Max
Travel Point on the panel. The engine does not need to be running.
5. Crank up the engine. Better RPM accuracy is achieved if the engine is allowed to warm up before
proceeding.
6. Select Start Calibration.
Finally, set the Minimum, Idle and Maximum RPMs in the Throttling Menu.

Manual Operation
Use the following steps for manual operation:
1. Ensure that the Auxiliary Engine Stop (if fitted) is not activated.
2. Turn the key switch to the run position.
3. Press and hold the Run button.
4. Release button when engine starts.
5.1 Throttle Control
The ECU determines how the engine responds to the throttle requests and will not allow the engine speed to fall
below the ECU minimum RPM or go above the ECU maximum RPM. The ECU minimum and maximum RPM
values are determined by the ECU “payload” and typically require the engine manufacturer’s configuration tool to
adjust them. The ECU will honor RPM requests that are above the ECU’s minimum RPM as well as RPM
requests that are below the ECU’s maximum RPM.
Therefore, to avoid confusion, it is best not to set the panel’s Minimum Requested RPM below the ECU’s
minimum RPM or set the panel’s Maximum Requested RPM above the ECU’s maximum RPM.
For example, the panel’s Minimum Requested RPM is set to 800 RPM, yet the ECU payload defines the engine
minimum speed to be 900 RPM. In this case, the engine will not run at 800 RPM despite the control panel
requesting a lower engine speed. The ECU will ignore all RPM requests that are below 900 RPM, resulting in a
minimum speed of 900 RPM.
5.2 Ramp Throttle
The standard Ramp Throttle uses the rabbit and turtle buttons to adjust the requested engine speed. All throttle
requests are sent directly to the engine using CAN throttle control.
