Chapter 16: Load Controllers
‘Closed Loop’ Windows
Load control window
A small ‘Load Control’ Window appears when in brake mode with the load controller connected and ‘Linked’.
It is visible only from the main DYNO screen as that is control screen for testing.
This is used to control the testing, set the type of testing we wish to do and any settings
required.
This window can be ‘dragged’ to any location on the screen/screens so that it doesn’t
obscure vision. It can even be made transparent with the ‘AB’ icon button.
Note: For actual use during testing also refer to the appropriate ‘Quick start guide’ for your dyno type.
Manual testing load control
Manual Load Control: Enable ‘Manual’ control. You can set a target RPM/speed for the control system to
maintain.
Pressing the large “MANUAL START” button now activates the load controller so that it powers the brake and maintains
the target RPM/speed. You can test this by gradually accelerating up to that RPM or speed until the brake begins to hold
it constant, adjust as required.
The target RPM/speed can be adjusted in slow or fast steps with 3 options-
1) Use mouse to drag the by the knob by the edge (hold Left button for slow, Right for fast)
2) Adjust with the PC’s F1-F4 keys (F1/F2 slow, F3/F4 fast)
3) Manually entering a figure (press the icon of dial with “SET” on it)
Tip- The RPM step size applied to the F1–F4 keys can be set so that it coincides with RPM points in the fuel/ignition
table of an engine ECU, this speeds up ECU mapping i.e. to quickly jump from one RPM ‘cell’ to another.
This is done from the setting in the ‘Run Options, Files and Information’ window shown soon.
Manual Target Fast Setting: Opens a window to directly enter a target RPM/speed.
Note: The max limit set in this screen comes from the value used in the menu ‘Scales’.
The min limit comes from the setting in the ‘Run Options, Files and Information’ window shown soon.
