DPF - This indicator will illuminate to show that regeneration is required.Regeneration Triggers
Regeneration may be required for the following reasons:Soot: The DPF will collect soot produced by the engine. Automatic regeneration will become active to reduce soot level.Sulfation Regeneration: The SCR will have sulfur build up over time. The ECM will calculate sulfur buildup and once accumulation hits a threshold, will trigger regeneration to reduce sulfur.SCR Maintenance: Regeneration is performed to maintain the SCR system.Regeneration System Warning Indicators
Illustration 1 g02117258The DPF Indicator will illuminate solid when regeneration is required. Regeneration should be performed as soon as possible.Note: In some situations, the DPF indicator may stay illuminated after regeneration ends. The illuminated DPF indicator indicates that complete regeneration has not been performed. Complete regeneration is when the soot has been depleted or all the criteria for one of the other regeneration types have been met. If the DPF indicator stays illuminated, perform regeneration without interruption. The DPF indicator will shut off when regeneration is complete.If the soot load is above a threshold or sulfur is high, then regeneration is required. The DPF indicator will illuminate and flash slowly.
Illustration 2 g06261252Once the amount of soot or sulfur has exceeded a higher threshold, the DPF indicator will flash at a fast rate, and the check engine lamp (CEL) will illuminate.
Illustration 3 g06261268Once the amount of soot or sulfur collected reaches a critical threshold level, a red "STOP" lamp will illuminate in addition to the DPF indicator and CEL. 5 minutes after reaching the critical level, the engine will go to low idle. Three minutes after going to low idle, the engine will shut down. A key cycle will allow the engine to start again, but will again go to low idle after 5 minutes, and shutdown 3 minutes later.Once the amount of soot reaches an even more critical threshold level, the regeneration will be locked out. This only occurs for high soot. Regeneration will not be locked out for high sulfur. When the lock out occurs, regeneration can only be done through Cat Electronic Technician (ET), by an authorized Cat dealer. The engine may be restarted, but will only run for 3 minutes before shutting down again.A fault code will be active for any DPF system-related issue. Follow the troubleshooting guide to rectify the issue.If the DPF loses function, or is tampered with in any way, the check engine lamp, and an amber action lamp (if equipped) will illuminate. A fault code will also annunciate. The lamps and fault code will remain active until the problem is rectified.
The engine and emissions control system shall be operated, used, and maintained in accordance with the instructions provided. Failure to follow the instructions could result in emissions performance that does not meet the requirements applicable to the category of the engine. No deliberated tampering with, or misuse of the engine emissions control system should take place. Prompt action is critical to rectify any incorrect operation, use, or maintenance of the emissions control system.
Carbon Dioxide (CO2) Emissions Statement
Emissions regulations require that the value of the CO2 emissions be reported to the end user. For this engine, 707 g/kWh was determined to be the CO2 value during the EU type approval process. This value was recorded in EU type approval certificate. This CO2 measurement results from testing over a fixed test cycle, under laboratory conditions, with a parent engine representative of the engine family. This value shall not imply or express any guarantee of the performance of a particular engine.
