Manual Operation
Use the following steps for manual operation:
1. Ensure that the Auxiliary Engine Stop (if fitted) is not activated.
2. Turn the keyswitch to the run position.
3. Turn the keyswitch clockwise to the start position and hold until the engine successfully starts.
4. Release the keyswitch.
If the engine fails to start, the keyswitch must be returned to the off position prior to subsequent start attempts.
Note:
The ECU will not preheat unless conditions warrant. If necessary, starting the engine may be
attempted by turning the key to the start position without waiting for preheat to expire.
6.1 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.
Note:
The panel’s Minimum Requested RPM and Maximum Requested RPM can be configured using the
CANplus
TM
Software Suite, or via menus within the display (if enabled by PIN). See the
section for more information.
6.2 Ramp Throttle
The standard Ramp Throttle uses a momentary rocker switch to adjust the requested engine speed. All throttle
requests are sent directly to the engine using CAN throttle control.
Note:
Throttle control requires CAN throttling to be enabled in the ECU. CAN throttling is also known as
Torque Speed Control or TSC1.
When first started, the requested engine speed is Idle RPM.

Pressing and releasing the rabbit icon increases the speed by the switch/rotary increment value
(default = 50 RPM)
