26 V-MAC Co-Pilot Operator’s Manual Aftertreatment DPF Parked Regeneration Aftertreatment diesel particulate filter (DPF) parked regeneration allows the operator to start and/or stop the regeneration manually when the vehicle is parked. The operator is notified that a regeneration is needed when the icons on the DPF Smart switch illuminate. The operator should perform the regeneration as soon as possible. Please refer to the instructions below on how to use the DPF Smart switch for parked regenerations. 1 Move the vehicle to a safe location, apply the park brake and allow the engine to idle. Note: When a regeneration is in process, the engine exhaust gas temperature (EGT) will be elevated. DO NOT park the vehicle with the exhaust outlet under low hanging overhead flammable objects such as trees, awnings, etc., that could be damaged by elevated exhaust temperatures. DO NOT attempt to regenerate inside a garage or enclosed area if the tail pipe is attached to an exhaust ventilation system as the hose material may not be rated for the high temperature. 2 Press and hold the top part of the DPF Smart switch momentarily to initiate the regeneration. 3 During regeneration, the icons on the switch will shut off. The high exhaust system temperature (HEST) indicator on the instrument cluster will light up to notify of high exhaust temperatures. 4 For catalyzed exhaust aftertreatment systems, the engine speed (RPM) will ramp up to around 1,100 RPM. For non-catalyzed exhaust aftertreatment systems, the engine will continue to idle during the regeneration. 5 Regeneration will take between 20 and 30 minutes to complete. 6 After regeneration has completed and the exhaust temperature has returned to normal, the HEST indicator will shut off. 7 If the regeneration process needs to be stopped and performed at a later time, please refer to “Aftertreatment DPF Inhibit/Stop Regeneration”, page 27 for information.
CAUTION Failure to perform an aftertreatment DPF regeneration in a timely manner after notification may result in engine derate, clogged or damaged DPF, and engine shutdown.
