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 through 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 regeneration is allowed when the soot level is equal to or greater than 15%. The machine must be stationary, the parking brake must be applied, and the engine must be at low idle in order to perform a manual regeneration.Disabled: When the regeneration system is in disabled mode, automatic regenerations will not be performed.Regeneration System Warning Indicators
Illustration 2 g02117258Indicator will illuminate when DPF soot load is greater than 90%Regeneration should be performed as soon as possible. Machine operation may not allow an automatic regeneration to take place. A manual regeneration should be performed as soon as possible.Indicator will turn off once DPF regeneration has started.Note: In some situations, the DPF indicator may stay illuminated when the soot load is below 90%. The illuminated DPF indicator indicates that a complete regeneration has not been performed. A complete regeneration is when the soot level is reduced to 0%. If the DPF indicator stays illuminated, perform a regeneration without interruption until the soot level is reduced to 0%. A complete regeneration will reset the DPF indicator.
Illustration 3 g02117259If the amount of soot collected in the DPF has reached a level that a regeneration is required, the DPF indicator and an action lamp will illuminate. Stop the machine and apply the parking brake. With the engine at low idle, initiate a manual regeneration. Engine power will be slightly derated if the machine continues to operate.
Illustration 4 g02117261After a certain period, if no action is taken to regenerate an action alarm will activate. After 5 minutes with the action alarm active, the engine will automatically be taken to low idle. A manual regeneration is required at this time. A complete regeneration will unlock the forced low idle speed. Cycling the engine start switch key will unlock the forced low idle speed. Once the engine has been in the forced low idle strategy for approximately 10 minutes, regeneration will be locked out. At this time, a regeneration can only be done through Caterpillar Electronic Technician (ET), by an authorized Cat dealer.After a certain amount of time, engi
