18000 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
A8. DPF Switch (Tier 4 Equipped)
NOTE: DPF = Diesel Particulate Filter (cranes equipped
with Tier 4 engine).
The DPF switch is a three position switch. Top position is
momentary. Center and bottom position are maintained.
CENTER position is for NORMAL engine operation.
Regeneration of the DPF will occur automatically.
Press TOP of rocker to START manual stationary
regeneration. Release switch back to center position.
Cummins ECM will control a DPF regeneration if necessary.
It is normal for the DPF High Temperature lamp to illuminate.
Perform a manual stationary regeneration only if indicated
by the DPF diagnostic in the Tier 4 Engine Diagnostics —
Cummins QSX15 Tier 4, (see DPF Condition (Tier 4) for
details).
NOTE: A guard over the top of the rocker prevents
accidental manual regeneration of the DPF.
Press BOTTOM of rocker to INHIBIT active regeneration.
The amber LED in the rocker will glow.
Use INHIBIT only for special circumstances where it is
desirable to disable active regeneration. Prolonged engine
operation with INHIBIT on will cause the DPF to fill with soot.
Too much soot could cause the engine to stop. If that occurs
it will be necessary to clean the DPF before the engine can
be restarted.
See Engine Manufacturer’s Manual for additional information
regarding stationary regeneration and DPF inhibit operating
instructions.
