• Severe Inducement:
The audible alert sounds in Continuous alarm.
On the warning display (7), the engine system caution
lamp, DEF system caution lamp, and hybrid caution lamp
light up in red.
The action level “L04” is displayed in red (3).
Press F6 to display the “SCR Information” screen.
“SCR Information” screen message (5): “4 Engine power is
under heavy deration.”
Due to the further deration of engine power, capability the
machine will be limited further.
The hybrid system output is also limited, and the swing
motor output is limited.
If the restoration of the EGR system abnormality is not per-
formed, engine power will kept be derated.
Engine power can be restored temporarily from power derate. If Inducement advances to “Severe Induce-
ment” and it becomes necessary to restore engine power, use the engine power restoration function to
move the machine to a safe place and contact your Komatsu distributor. This engine power restoration
works only when the Inducement status is “Severe Inducement” and relieves back temporarily to the power
deration of “Low level Inducement”. The operator can restore engine power through the machine monitor.
For the engine power restoration procedure, refer to the section of “Temporary Restoration from Induce-
ment” in this manual.
TEMPORARY RESTORATION FROM INDUCEMENT
Temporary Restoration from Inducement is one of the Inducement strategies allowed to be included in Urea
SCR systems.
In case the Urea SCR system advances to “Severe Inducement”, engine power is derated heavily. This may
cause difficulties of moving the machine to a safe place for adding DEF or troubleshooting and correcting abnor-
malities of the Urea SCR system. For temporary remedies from these difficulties the operator can restore engine
power for a short time to the deration of “Low level Inducement” through the machine monitor. “Temporary Re-
storation from Inducement” does not regain full engine power.
“Temporary Restoration from Inducement” can be activated only when the Urea SCR system is in “Severe In-
ducement”. The maximum duration is limited to 30 minutes in each restoration operation, and only 3 operations
are allowed.
All the abnormalities of the Urea SCR system need to be corrected to regain another restoration capability.
If the system advances to “Severe Inducement”, utilize “Temporary Restoration from Inducement” immediately.
Procedure to activate “Temporary Restoration from Inducement”
1.
Press F6 to display the “SCR Information” screen when
the Standard screen is on, only when the Urea SCR sys-
tem is in “Severe Inducement”.
