EXPLANATION OF COMPONENTS
The inducement strategy progresses in 4 levels, "Warning",
"Continuous Warning", "Low level Inducement", and "Severe In-
ducement". The Inducement strategy includes visual alert by
the Engine system caution lamp (1), DEF system caution lamp
(2), and Action Level displayed on the machine monitor (3), au-
dible alert by a buzzer and stepwise engine power deration that
advances to speed limitation to low idle. Engine power deration
starts with Action Level "L03 (Warning, Continuous Warning
and Low level Inducement)" and advances to further deration
when "L04 (Severe Inducement)" is displayed. Once the sys-
tem advances to "Severe Inducement", the engine power will
be further derated. If "L03" is displayed, move the machine to a
safe place and contact your Komatsu distributor.
