Regeneration Indicator Lamps and Controls
Illustration 1 g06534334
The engine may be equipped with one of the control panels pictured above.
(1) "DPF" Indicator lamp
(2) "HIGH EXHAUST TEMPERATURE" indicator lamp
(3) "REGENERATION DISABLED" indicator lamp
(4) "START KEY" switch
(5) "DIAGNOSTIC" lamp
(6) "SHUTDOWN" lamp
(7) "IDLE SPEED" switch
(8) "REGENERATION" switch
(9) "HIGH SPEED REGENERATION" enable switchNote: For further information about the monitoring system, refer to this Operation and Maintenance Manual, "Monitoring System".
HIGH EXHAUST SYSTEM TEMPERATURE (HEST) - This indicator lamp illuminates to show that regeneration is active. This indicator lamp turns off when the regeneration is complete.
DPF - This indicator lamp illuminates to show that regeneration is needed. This indicator lamp illuminates when the soot level reaches 80%.
REGENERATION DISABLED - This indicator lamp illuminates to show that regeneration has been disabled.Regeneration Controls
Regeneration Control Switch
Illustration 2 g02333653
"REGENERATION" control switch
The position of the "REGENERATION" switch in the side view is the MIDDLE position.
Note: The MIDDLE position of the switch is the default position for low and high-speed regenerations.Note: Some OEMs use other means of activating a forced regeneration such as a touch screen interface.
"FORCE REGENERATION" - Press and hold in the top of the switch for 3 seconds to start regeneration.
"DISABLE REGENERATION" - Press and hold in the bottom of the switch for 3 seconds to disable regeneration.Note: To re-enable the regeneration, cycle the engine "START SWITCH KEY" or press and hold in the "FORCE REGENERATION" switch for 2 seconds.Note: If the engine "START SWITCH KEY" is cycled while the regeneration system is disabled via the "DISABLE REGENERATION" switch, press and hold in the "DISABLE REGENERATION" switch for 3 seconds to reinitiate the disable regeneration.OK to Elevate Idle Switch
Illustration 3 g02333673
"OK to Elevate Idle Switch" switch
The position of the "OK to Elevate Idle Switch" switch in the side view is the LOCKED position.
OK to Elevate Idle Switch - Pressing in and locking the "OK to Elevate Idle" switch enables the engine ECM to elevate engine speed automatically when needed. For example, if the engine is running at low idle and a DPF regeneration is activated, having the "OK to Elevate Idle" switch in the LOCKED position will allow the engine speed to increase in order for the DPF regeneration to occur.Note: This switch is only available on engines with instrument panels supplied by Cat.Soot Level Monitoring
Illustration 4 g02228033The soot level monitor indicates the level of soot that has accumulated within the DPF. The five marks on the monitor represent the percentage of soot within the DPF. The first mark indicates 0% soot level. The second mark indicates 25% soot level. The third mark indicates 50% soot level. The fourth mark indicates 75% soot level. The last mark indicates 100% soot level. The soot level monitor may be used to optimize DPF regenerations based on the work cycle of the engine. If operating conditions do not allow for automatic regeneration, manual regeneration should be performed before the soot level gauge indicates 100%Note: The soot level monitor may not be applied to all engines. Some OEM's may also use a different method of displaying soot load of the DPF. Refer to OEM operation manual for explanation.Modes of Regeneration
Automatic
The engine control module (ECM) uses multiple electrical inputs from the engine to determine the best time for the automatic regeneration. Automatic regeneration may take place throughout the operating cycle of the engine. The automatic regeneration may start when the engine is at the low idle speed or when the engine is at normal operating speed. The "HEST" indicator lamp is illuminated when regeneration is being performed.If the automatic regeneration starts while the engine is at the low idle speed, the engine may be returned to normal work at any time. Returning to normal work may stop the regeneration. The ECM will continue to monitor inputs to determine the best time to restart the regeneration.Interruptions of the regeneration are acceptable. If regeneration needs to be stopped for any reason, press the DISABLE REGENERATION switch or turn off the engine.Note: An automatic adjustment of engine speed may be noticed during the automatic regeneration. If the engine is taken to a low idle speed while regeneration is occurring, the engine speed may remain elevated in order for the regeneration to continue.
