Figure 21 — Minimum Engine Speeds for MP7 with Cat DPF Vehicle 21173561
Note: Beginning with 21198958 and newer software, the only requirement for
aftertreatment diesel particulate filter (DPF) regeneration on vehicles equipped with
an MP7 with non-catalyzed DPF and PTO is no less than 650 RPM. Altitude and
temperature are no longer factors for aftertreatment diesel particulate filter (DPF)
regeneration and PTO operation.
Aftertreatment DPF Regeneration and PTO
Engaged
If aftertreatment diesel particulate filter (DPF) manual stationary regenerations with
the power takeoff (PTO) engaged are required, the vehicle must be configured as
follows:
•
Set parameter Enable Manual Regen During PTO (JAC) to “Yes” or “On”
using VCADS. This parameter can be found in the “Misc. Vehicle Settings”
section in Parameter Programming. (A connection to Central Systems is required
to set parameter ID JAC.)
•
Initiate Manual Stationary Regeneration using the DPF smart switch.
•
Ensure the electronic hand throttle (engine speed control) is active. The
engine speed (RPM) must be set to greater than the minimum speeds listed in
“Aftertreatment DPF Regeneration and PTO Operation”, page 44.
If the vehicle is not configured as listed above, manual stationary aftertreatment diesel
particulate filter (DPF) regeneration with the PTO engaged will not occur. When
aftertreatment diesel particulate filter (DPF) regeneration does not take place, the DPF
will become soot-loaded, resulting in engine derate and eventual engine shutdown.
