Temporary Restoration from Inducement
Temporary Restoration from Inducement is the 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. Note that “Tempo-
rary Restoration 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 unless all the abnormalities of the Urea SCR system are corrected.
If the system advances to “Severe Inducement”, utilize “Temporary Restoration from Inducement” immediately.
