7747470_125 Volvo.Penta Cooling unit

Stopping the engine immediately after the engine has been working under load can result in overheating of turbocharger components.Refer to the Operation and Maintenance Manual, "Engine Stopping" procedure to allow the engine to cool and to prevent excessive temperatures in the turbocharger housing.
Allow at least 2 minutes after shutting down the engine before you turn the battery disconnect switch to OFF.
Definitions
Observe the following definitions.Impeded EGR valve - Something preventing the EGR valve from operating normally (i.e opening and closing).Self-correct - Fault condition no longer exists. An active fault code will no longer be active.Notification - Action taken by the system to alert the operator of pending Inducement.Inducement - Engine derates, vehicle speed limits, or other actions intended to prompt the operator to repair or maintain the emission control system.First occurrence - When an escalating time inducement fault code becomes active for the first time.Repeat occurrence - When any escalating time inducement fault code becomes active again within 40 hours of the first occurrence. Engine must run for 40 hours without tripping any escalating time inducement fault before returning get back to first occurrence times.Safe Harbor Mode (Worldwide) - Safe Harbor Mode is a 30 minute engine run time period. During the Safe Harbor Mode the engine can be operated with full power after reaching a level 2 severe or level 3 inducement depending on inducement strategy selected. Once in level 3 inducement, the operator can perform a key cycle and the engine will enter Safe Harbor Mode. Safe Harbor Mode can only be implemented up to three times.
It is essential to take prompt action to rectify any incorrect operation, use, or maintenance of the engine emissions system in accordance with the rectification measures indicated by the warnings listed on the following pages.
Inducement Strategy for Escalating Time Inducement Faults
The following warnings and inducements are triggered as a result of impeded EGR valve.
Illustration 1 g03677836Reduced PerformanceThe check engine and emissions malfunction indicator lamp will illuminate for any inducement-related fault and a level 1 inducement will occur for a duration of 36 hours. There is no repeat occurrence for level 1 faults.Reduced TimeThe check engine and emissions malfunction indicator lamp will illuminate for a level 1 inducement-related fault and a level 1 inducement will occur for a duration of 18 hours. There is no repeat occurrence for level 1 faults.
Illustration 2 g03676138Reduced PerformanceIf a fault condition exists for the entire duration of inducement level 1, the strategy advances to inducement level 2. The check engine lamp and the emissions malfunction indicator lamp will illuminate and flash slowly. The level 2 inducement occurs for a duration of 64 hours for first occurrence. For repeat occurrence, a level 2 inducement fault will occur for a duration of 5 hours.The engine will have a 50% derate. If the fault is not corrected before the inducement duration ends, the engine will become 100% derated. The engine will also be limited to 1000 rpm or low idle, whichever is greater. No further inducements will occur for "Reduced Performance" configuration. Safe Harbor Mode is allowed for three key cycles.Reduced TimeIf a fault condition exists for the entire duration of inducement level 1, the strategy advances to inducement level 2. The check engine lamp and the emissions malfunction indicator lamp will illuminate and flash slowly. The level 2 inducement will occur for a duration of 18 hours for first occurrence. For repeat occurrence, level 2 inducement fault will occur for a duration of 108 minutes.
Illustration 3 g03676141Reduced TimeIf configured to "Reduced Time" and a fault condition exists for the entire duration of inducement level 2, the strategy advances to inducement level 3. The check engine lamp and emissions malfunction indicator lamp will flash at a fast rate. A red stop lamp will also illuminate solid. The engine will have a 100% derate and be limited to 1000 rpm or low idle, whichever is greater. If, the final inducement action in Cat ET is set to "Idle Down", then engine will continue to idle at derated condition. If set to "Shutdown", engine will shut down after 5 minutes. A key cycle will allow safe harbor mode to initiate. Safe harbor is allowed up to three times. After safe harbor, the engine will be in level 3 final inducement. If set to "Shutdown", the engine may be restarted, but will only run for 5 minutes at derated condition before shutting down again. This action will continue until the issue is resolved.Note: Contact your Cat dealer for repairs if a fault occurs.Carbon Dioxide (CO2) Emissions
Euro Stage V emissions regulations require that the valve of the CO2 emissions be reported to the end user. FOr this engine, 694.74 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.
