Inducement Strategy for abnormalities recurrences within 40 hours
The Urea SCR system continuously monitors its operation conditions and stores information on inappropriate
operations including malfunctions. The stored information is utilized to monitor recurrences of abnormalities,
"Abnormality Recurrence Counter". "Abnormality Recurrence Counter" is required by the authorities. The recur-
rence monitoring spans 40 hours and it monitors the abnormalities that trigger Inducement other than the
amount of DEF in the tank.
If another abnormality/abnormalities is detected within 40 hours after the previous abnormalities were corrected,
regardless of the level of the previous Inducement and whether the new abnormality/abnormalities is the same
as the previous ones or not, it is judged as a recurrence.
If a recurrence occurs, "Severe Inducement" will be activated.
Inducement in the recurrence resumes counting time at the time when the previous abnormalities were correc-
ted if the previous Inducement is in " Warning" or "Continuous Warning" or "Low level Inducement". The alerts
resume the previous Inducement.
If this occurs, utilize "Temporary Restoration from Inducement" and move to the machine to a safe place, and
contact your Komatsu distributor.
The maximum duration of power restoration is 30 minutes and 3 operations are allowed.
To activate "Temporary Restoration from Inducement", refer to the "Temporary Restoration from Inducement"
