DPF Operation
24
Initiating a Regeneration
IMPORTANT: The DPF system operates using electrical
voltage supplied by the truck’s alternator system. Due to the
large current draw required by the DPF, the regeneration
process should only
be initiated during daytime hours while
the truck is expected to be operating at highway speeds
(above 1150 rpm) for a minimum of one hour. Do not operate
the DPF while the truck is stopped, idling or moving slowly in
traffic. If this condition occurs, the regeneration process may
automatically be cancelled.
The DPF control system determines when a regeneration is
needed by displaying a steady amber DPF STATUS indicator
light on both the Exhaust Monitor and the Regeneration
Switch. The amber light must be illuminated to initiate a
regeneration. Pressing the regeneration switch when no amber
light is present has no effect and will not start a regeneration.
When the TrPac APU has operated for a period of time, a
steady amber DPF STATUS indicator light on the Exhaust
Monitor and the Regeneration Switch will illuminate
indicating a regeneration needs to be initiated by the driver.
