15.5 Monitoring DEF Quality
The quality of Diesel Exhaust Fluid (DEF) is monitored by the genset controller.
When the DEF quality begins to deteriorate (or something other than DEF is put
into the DEF tank, or the sensor is disconnected/malfunctioning), the genset
controller displays messages alerting the operator as to the condition of the DEF
quality. See table below.

■
After 180 minutes of run time with a DEF quality issue,
the engine shuts itself down. This is the first of four
shutdowns allowed by the engine.
Note: The genset controller’s 10-minute run time
limitation is still active within the 180-minute engine run
time limit. Thus, up to seventeen restarts by the genset
controller are possible within the 180-minute engine
controlled run time.
■
The engine may be restarted, but the run time is
lessened to 30 minutes. At the 30-minute mark, the
engine shuts itself down. This is the second of four
allowed shutdowns. The genset controller’s 10-minute
run time limitation is still active. Thus, up to three
restarts by the genset controller are possible within the
30-minute engine controlled run time limit. On the fourth
shutdown, the engine controller will lock out the engine.
The engine can only be unlocked by a Cummins service
technician.
