(17) Right Travel Pressure SensorWhen one-touch low idle switch (10) is pressed, and the machine is not under load (all levers and pedals in the neutral position), the engine RPM can be set lower than the RPM set by the AEC "Stage 2" setting. When normal operations resume, the engine RPM will return to match the Engine Speed Dial 2 setting.The operational condition of the machine is detected by the implement pressure sensor of the joystick and the travel sensors of the travel pedal .Using the One-Touch Low Idle Feature
The one-touch low idle feature will activate during all "stopped" conditions of the implement, swing, travel, and tools. However, when the "One-Touch Low Idle" switch is pressed, the control will lower the engine speed. The speed is reduced to a speed dial setting of 2 or approximately 1100 rpm. This control overrides the AEC.Release of the One-Touch Low Idle
The one-touch low idle switch will be released when any of the following conditions occur:
The one-touch low idle switch is pressed again.
An increase in pilot pressure sensed by the implement pressure sensor.
An increase in pilot pressure sensed by the travel pressure sensor.
A pressure switch that is related to a tool is set to the ON position.
An increase in pump pressure sensed by the pump pressure sensors.The engine RPM is different after the switch has been released. The different speed will depend on the conditions of the release.
The engine RPM matches the engine speed dial setting when the one-touch low idle feature is released by operating an implement or tool.
The engine RPM is set by the AEC when the one-touch low idle switch is used to release the one-touch low idle function. The engine RPM will be affected by the following conditions:
When the AEC "Stage 1" is selected, engine RPM will be set to the AEC "Stage 1" setting. That setting is approximately 100 RPM lower than the current setting of the engine speed dial RPM.
When the AEC "Stage 2" is selected, engine RPM will be set to the AEC "Stage 1" setting. That setting is approximately 1100 RPM.
Engine RPM matches the RPM of current engine speed dial settings, when engine RPM is lower than the AEC "Stage 2" setting. The setting of this RPM is not based on a setting of the AEC function.Engine Speed Protection
Delayed Engine Shutdown

(12) Hydraulic Lock SolenoidThe Delayed Engine Shutdown function allows the engine or exhaust system to run at low idle after the key is turned OFF. This function provides a cool down period for the engine or exhaust system. During the cool down period the engine burns soot that has collected in the exhaust system.
