One Touch Low Idle

When the one touch low idle switch is pressed and the machine is not under a load, the engine speed can be lowered by more than the speed setting of the AEC second stage. When normal operations have resumed, the engine speed for the dial setting will return to the corresponding rpm. The one touch low idle feature will activate during all "stopped" conditions of the implement, swing, travel, and tools. The one touch low idle switch, the implement pressure switch, and the travel pressure switch send input signals to the Machine ECM. The Machine ECM processes the input signals and sends corresponding output signals to the Engine ECM to control the engine speed. The following components are in the OFF position: theimplement pressure switch, the travel pressure switch, and the attachment (ATT) pedal pressure switch. However, when the one touch low idle switch is pressed, the control will lower the engine speed to the speed of the "2" setting of the engine speed dial to approximately 1020 rpm. This control overrides the AEC.

The one touch low idle will be released when any of the following conditions occur: -The one touch low idle switch is pressed again. -The implement pressure switch is set to the ON position. -The travel pressure switch is set to the ON position. -Apressure switch that is related to a tool is set to the ON position.
