V-MAC Co-Pilot Operator's Manual 47
Aftertreatment System Conditioning and PTO
Operation
When the aftertreatment system conditioning cycle becomes active and a power
takeoff (PTO) is engaged, the engine speed (RPM) should remain at the PTO set
speed, provided the RPM and PTO engage inputs are enabled. The PTO must be
activated by a switch to provide PTO engagement and speed input to the vehicle
electronic control unit (VECU) (so that the engine control module (ECM) knows
the status of the PTO). If these inputs are not enabled and the PTO is engaged,
aftertreatment system conditioning will increase RPM when commanded, resulting in
damage to the PTO, equipment or to the product being unloaded.
Note:
When selecting a PTO on a vehicle with a aftertreatment diesel particulate filter
(DPF), it is important that the PTO be specified to have a maximum rated speed above
the minimum RPM. Please refer to Figures 18 through 21.
Note: For vehicles equipped with the catalyzed DPF and prolonged periods of engine
idle time are required, the engine speed control should not be used to increase RPM.
The engine must be allowed to idle as normal. If prolonged engine idling is necessary,
it is recommended that the ECM be programmed with California Air Resources Board
(CARB) 2010 compliant files. Please refer to the
Emission Control Systems for MACK
Class 8 Diesel Engines (MACK MP7 and MP8 Engines) manual for more information.
