When enabled, this feature allows the user to configure Low Idle Speed. When the switch is held in either adjust position, the idle speed gradually increases or decreases by the calibrated increment. Pressing and releasing the switch in one direction raises the Low Idle speed by a calibrated increment, such as 25 RPM, and pressing and releasing the switch in the other direction lowers the idle speed by the same calibrated increment. The Low Idle speed adjustment switch enables the driver to adjust the Low Idle speed using a two-position momentary toggle switch. The default Low Idle speed is defined by the calibration. Low Idle speed is controlled by the low idle governor which prevents the Engine speed from dropping below a predetermined value by controlling Engine fueling. The Low Idle speed can be set to the desired value using INSITE™, however the Operator can override this value using an OEM-supplied idle speed adjustment switch. This feature can reduce the amount of fuel burned and decrease cab noise and vibration. How to Adjust Low Idle Speed on Cummins INSITE Software ?Īdjustable Low Idle Speed on Cummins INSITE Software
