Description:
Idle RPM Limit is the maximum engine rpm in the idle mode. Idle mode occurs if the engine rpm is set using the cruise control On/Off switch and the Set/Resume switch. The actual upper limit of this parameter is determined by the programmed Top Engine Limit. The lower limit is determined by the programmed Low Idle Engine rpm.
Available:
All electronically controlled on-highway engines covered in this handbook
Range:
Advantages:
Being able to electronically control engine rpm offers more precise control than a hand throttle. The ability to limit maximum engine rpm in the Idle mode saves fuel and prevents unnecessary engine wear.
Disadvantages:
None
Recommendations:
For non-PTO operations where overnight idling is the primary usage of this feature, set the Idle/PTO RPM Limit between 900 and 1100 rpm based on climatic conditions.
