REGENERATION CHART
Important Notes:
The DOC is a maintenance free device and will under normal
conditions remain operational for as long as the engine.
The DEF system requires maintenance of the filter situated in the
Bosch dosing pump at the required intervals (see scheduled
maintenance).
Using any fluid other then the proper DEF fluid will contaminate and
render the dosing system inoperable causing the engine to stop.
Should any contamination occur , then the tank needs to be
removed and cleaned before filling with the correct DEF fluid.
DEF fluid should only be used from clean receptacles or filtered
pumping systems.
Never use additives to change the DEF fluid properties.
1. Passive Regeneration
2. Mobile Active Regeneration
3. Stationary Active Regeneration
Continuous
Automatic
Manual
Passive regeneration occurs during most
of the equipment operating time.
1.
Timed:
mobile active regen is pre-set to
automatically occur
at 96 hour intervals
while
the equipment is working. Takes
15 minutes
to fully regenerate.
2.
Duty Cycle:
active regen may occur sooner
than 96 hours if passive regen is insufficient to
prevent PM soot loading approaching 50% in
the filter. Takes
30 to 45 minutes
to fully
regenerate.
A stationary (or parked) active regen is
manually initiated
by the operator using the
Regen Start switch. Takes
30 to 45 minutes
to
fully regenerate.
This is required when PM soot loading reaches
50% in the filter, shown by the DPF lamp.
Manual regen is required due to the active regen
function disabled by the Inhibit 'ON’ switch - or
because the system cannot reach the necessary
exhaust temperature or flow for duty cycle
initiated active regen to occur.
Continually removes PM soot from the
Diesel Particulate Filter when exhaust
temperature is above 220
°
C.
Removes any excessive build-up of PM soot from
the filter by raising the exhaust temperature
above 500
°
C with late injection fuel.
Removes any excessive build-up of PM soot

°
C with late injection fuel.
DPF exhaust and surface temperatures
are normal.
No indicator lamp will illuminate.
DPF exhaust and surface temperatures
are
higher than normal
due to regen.
The
HEST
(High Exhaust Temperature) lamp
may illuminate.
DPF exhaust and surface temperatures
are
higher than normal
.
The
HEST
(High Exhaust Temperature) lamp
may illuminate.
Equipment must be
stationary and parked in a
safe location
.
WARNING: Continued use of the Regeneration Inhibit position
will at first lead to warning messages being displayed on the
MidPort due to increased soot loading of the DPF core. Failure
to respond with a return to the Normal switch position will
eventually create a severe engine power derate and shutdown,
running in this condition until shutdown could also damage the
DPF core requiring replacement instead of cleaning.
