Regeneration Indicators
Regeneration Active - This indicator will illuminate in order to show that the CRS is active. This indicator shows that elevated emission temperatures are possible. This indicator will turn off when regeneration is complete.
DPF - This indicator will illuminate in order to show that a regeneration is needed. This indicator will illuminate when the soot level reaches 90%.
Regeneration Disabled - This indicator will illuminate in order to show that a regeneration has been disabled.Regeneration Switch
Force Regeneration - Press in the top of the switch for 2 seconds in order to begin regeneration.
Disable Regeneration - Press in the bottom of the switch for 2 seconds in order to disable regeneration.Note: The MIDDLE position of the regeneration switch is the default position for automatic regeneration.Note: You may return to normal operation at any point during a regeneration.Note: To re-enable automatic regeneration, cycle the engine start switch key or press and hold down the force regeneration switch for 2 seconds. If the soot level is above 15%, regeneration will begin if the machine is at low idle and is parked.Note: If the engine start switch key is cycled while the regeneration system is disabled via the disable regeneration switch, press and hold the disable regeneration switch for 2 seconds to reinitiate the disable regeneration.Soot Level Monitoring
Illustration 1 g02228033The soot level monitor indicates the level of soot that has accumulated within the DPF. The five marks on the monitor represent a percentage of soot within the DPF. The first mark indicates 0% soot level. The second mark indicates 25% soot level. The middle mark indicates 50% soot level. The fourth mark indicates 75% soot level. The last mark indicates 100% soot level. The soot level monitor can be used to optimize DPF regenerations based upon the work cycle of your machine. If machine conditions do not allow for an automatic regeneration, a manual regeneration should be performed before the soot level gauge indicates 100%. Modes of Regeneration
Automatic: The engine ECM uses multiple inputs from the engine and the machine to determine the best time to perform an automatic regeneration. Automatic regenerations can take place throughout the operating cycle of the engine. The regeneration active indicator will be illuminated when a regeneration is being performed. Interruptions of the regeneration are acceptable. If a regeneration is in progress and needs to be stopped for any reason, it is permissible to press the disable regeneration switch or turn off the engine.Note: Automatic adjustments of engine speed may be noticed during automatic regenerations. If a regeneration is taking place and the engine is taken to low idle, the engine speed may remain elevated in order to maintain the regeneration. Note: If an automatic regeneration is started while the engine is at low idle and the machine is taken back to work, this may stop the regeneration. The engine ECM will continue to monitor inputs to determine the best time to restart the regeneration.Manual: A manual regeneration is initiated by pressing the force regeneration switch. A manual
