DEF SEVERE INDUCEMENT ALARMS (DGC2020HD)
If a warning for DEF Severe Inducement is present,
consider it just like a “Check Engine Light” the reason for the
inducement alarm is available under the menu: Metering-
>J1939-> Active DTC.
“Def Severe Inducement PA” (PA=Pre-Alarm): This is a
notice to the operator to correct the issue before it escalates
to an alarm.
Pre-alarm is commonly active when the DEF tank is at a
low level, if the tank is refilled the Pre-Alarm is cleared and
the unit has no adverse effects.
“DEF Severe Inducement A” (A=Alarm): This is a notice to
the operator that an after treatment related DTC is causing
the unit to enforce 70% de-rated power and the unit will
not be allowed to carry full load. If the load is higher than
30% more than likely the control panel will show an “Under
Frequency” (81) warning or alarm.
NOTICE
Unit derate occurs at below 0% DEF level. If DEF level
is at empty, engine will shutdown. When refilling with
diesel fuel is required, refill DEF tank as well.
NOTICE
Generator derating occurs during soot levels 4 and 5.
Soot level 5 will cause the generator to shutdown If
this condition occurs contact your nearest authorized
service center.
