EC210 Throttle Control

The document provides service information about the auto idle function for an EC210C L Volvo machine. The auto idle function automatically decreases the engine speed when the machine is not operated for some time to lower fuel consumption. When the operator engages a control, the engine speed increases. It lists the input signals and parameters for the auto idle function and describes the releasing conditions for deactivating auto idle, such as hydraulic pressure exceeding 0.5 MPa or operation of certain switches. It also notes the auto idle delay time can be adjusted from 3 to 10 seconds using TechTool software.

The purpose of the auto idle function is to automatically enter idle mode when the machine is not operated for some time.
When the machine is put in idle mode engine speed is decreased in order to lower the fuel consumption.
After the engine has decelerated, if the operator touches one of the remote control valves (control levers, pedals) or turns the
engine speed control switch or pushes one of the rotator switches, engine speed is increased to the selected speed of the engine
speed control switch. For the wiring diagram, see Wiring diagram SCH08.
