Prevention Of High Speed Start Of The Engine
In a conventional excavator, the engine will start in high speed with the engine speed dial in a high position (10) after the engine has been stopped. The following information will describe the actions that are designed in order to prevent a high speed start.When the engine key start switch is placed in the OFF position, the governor actuator will stop. The governor lever is maintained in the identical position. The engine will restart at a RPM of 1300 or 1000 rpm, if the engine is stopped and the second stage of the AEC is operating. The engine will also restart at a RPM of 1300 or 1000 rpm, if the engine is stopped and the low idle switch is in the ON position. This function is designed to keep the governor actuator in position when the operation is terminated. Any of the following conditions can cause the termination:
A control lever or a pedal is operated.
A implement/swing switchis activated.
A travel switch is activated.
A boom raise pressure switch is activated.
The engine speed dial is operated.
The AEC switch is operated.
The power mode switch is operated.Then, the engine speed will correspond to the position of the engine speed dial. Operation of the low idle switch
