DOOR AS-L.H. 9V8947 - Caterpillar

Disable Regeneration - Press in the bottom switch for 2 seconds to disable regeneration.Note: If equipped with a rocker style switch, the MIDDLE position of the regeneration switch is the default position for automatic regeneration.Note: If the engine start switch key is cycled or the "Force Regeneration" switch is pressed for longer than 2 seconds the system will no longer be disabled. When the "Force Regeneration" switch is pressed and "Time to Regen" is less than 8 hours, 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.Modes of Regeneration
Automatic: The Electronic Control Module (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, it is permissible to press the "Disable Regeneration" switch.Note: Automatic adjustments of engine speed may be noticed during regenerations. If a regeneration is taking place and the engine is taken to low idle, the engine speed may remain elevated to maintain the regeneration.Note: If the machine returns to work while an automatic regeneration is active, the regeneration may be stopped. The 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 will only be allowed if the "Time to Regen" is less than 8 hours. If the "Force Regeneration" switch is pressed before "Time to Regen" is less than 8 hours, then “Regen not Required” will be displayed. The machine must be stationary, the parking brake must be applied, and the engine must be at low idle to perform a manual regeneration.Disabled: When the regeneration system is in disabled mode, automatic regenerations will not be performed. The DPF indicator will illuminate if a manual regeneration is required. The "Time to Regen" displayed on the performance screen will indicate the time until the next regeneration will be required. However, the DPF indicator may illuminate with time remaining on the display. When the DPF indicator illuminates, the operator must perform a manual regeneration.Regeneration Triggers
A regeneration may be required for the following reasons:Soot: The DPF will collect soot produced by the engine. An automatic regeneration will become active to reduce soot level.Start-Up Regeneration: A start-up regeneration is initiated by the ECM after a cold engine start. This regeneration is performed to heat the system to a required temperature for Diesel Exhaust Fluid (DEF) dosing to begin.SCR Maintenance: A regeneration is performed to maintain the SCR system.ARD Maintenance: A regeneration is performed to maintain the ARD system.Regeneration System Warning Indicators
