This Diagram Is For The M325C MH One Touch Low Idle Control. (1) Engine speed dial (2) Engine and pump controller (3) Engine (4) One touch low idle switch (5) Implement swing pressure switch (6) Electronic control moduleWhen the one touch low idle switch (4) is pressed and the machine is not under a load, the engine speed can be lowered by more than the speed of the setting of the second stage of the AEC. When normal operations have resumed, the engine speed for the dial setting will return the corresponding RPM.Start-up Of The One Touch Low Idle
The one touch low idle feature will activate during all "stopped" conditions of the implement, swing, travel and tools. The following components are in the OFF position: implement swing pressure switch, the travel pressure switch (right), the travel pressure switch (left), the attachment pedal pressure switch and the straight travel 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. Approximately 1100 rpm for the 312C and 315C. Approximately 1020 rpm for the 319C, 320C, 321C, 322C, 325C, and 330C. This control overrides the AEC.Note: The 312C has only one travel pressure switch and the 315C has only one travel pressure switch.Release Of The One Touch Low Idle
The one touch low idle will be released when any of the following conditions occur:
The one touch low idle switch (4) is pressed again.
The implement swing pressure switch is set to the ON position.
A travel pressure switch is set to the ON position.
A pressure switch that is related to a tool is set to the ON position.The engine speed is different after the switch has been released. The different speed will depend on the conditions of the release.
The engine speed will be set to the setting of the engine speed dial, when the feature for one touch low idle has been released by an operation of the implement, swing, etc..
The engine speed will be set by the AEC. The speed will be set when the one touch low idle has been released. The engine speed will be affected by the following conditions:
When the first setting of the AEC is selected, the engine speed will be set to the speed of the first setting of the AEC. The speed is approximately 100
