Engine Regeneration/Inhibit
Switch
The regeneration/inhibit switch is a three-position rocker switch.
The top position is momentary. The center and bottom positions are
maintained. For more information on this switch, see Section 7 of
the Service Manual.
Active Position
The active center position is for normal engine operation. The
position does not require operator assistance under normal
conditions. This position allows the exhaust system to actively
(automatically) regenerate.
Manual Regeneration
If the Engine Information Screen in the Main Display indicates the exhaust
system requires a manual regeneration, press and release the top of the rocker.
The engine ECM will control a regeneration cycle.
The top of the rocker switch is momentary and the switch will return to the active
position after the top of the switch is pressed.
A manual regeneration will begin only if the engine is at low idle.
NOTE The top end of the switch has a guard that prevents accidental manual
regeneration.
The High Exhaust System Temperature (HEST) lamp may come on during
regeneration and remain on for a short time after regeneration.
Regeneration Inhibit
To prevent the exhaust system active (automatic) regeneration, press the
bottom of the rocker. The switch will remain depressed. The amber LED in the
rocker will glow. To re-enable active regeneration, manually return the switch to
the active position.
Do not use the Inhibit switch unless specifically instructed by a Manitowoc or
Cummins technical advisor.
The exhaust system regen inhibited icon indicates the after-treatment system
active (automatic) regeneration is prevented because the inhibit switch is in the
inhibit position.
For information on exhaust system-related faults, see the Main Display
Operation Manual.
See engine manufacturer’s operation and maintenance manual for information
on the after-treatment system and engine faults.
