Cummins/Onan QSK60-G19 NR2 Engine

The Cummins/Onan QSK60-G19 NR2 is a 60.2 L 16-cylinder turbocharged and low temperature after-cooled engine rated at 1800 rpm, producing up to 2715 kW. It powers generator sets from Cummins/Onan, including the DQKAN. It holds 378 L (99.9 gal) of oil and 681.4 L (180.0 gal) of coolant.

Common problems

The control will not allow the starter to attempt to engage or to crank Cranking lockout
Cause: Not specified in text
Some shutdown faults are bypassed Battle short mode
Output power of the genset is reduced in response to a fault condition Derate
Indicates that engine temperature may not be high enough for a 10 second start or proper load acceptance Low coolant temperature warning
Cause: Engine temperature is low
Indicates status of battery charging system (failure) Low and high battery voltage warning
Cause: Continuously monitoring battery voltage
Emergency stop
Fix: Annunciated whenever either emergency stop signal is received from external switch.
Derate
Fix: The Derate function reduces output power of the genset in response to a fault condition. If a Derate command occurs while operating on an isolated bus, the control will issue commands to reduce the load on the genset via contact closures or Modbus. If a Derate command occurs while in utility parallel mode, the control will actively reduce power by lowering the base load kW to the derated target kW.
Control system indicates a fault if the genset fails to start by the completion of the engine crack sequence Fail to start (overcrank) shutdown
Cause: Genset fails to start
Control has signaled starter to crank engine but engine does not rotate Fail to crank shutdown
Cause: Engine does not rotate
Can be set up to be a warning or shutdown Low coolant level warning
Cause: Set up in control
Battle short mode
Fix: If a bypassed shutdown fault occurs, the fault code and description will still be annunciated, but the genset will not shutdown. This will be followed by a fail to shutdown fault.
Battery indicates impending failure Weak battery warning
Cause: Control system tests the battery each time the genset is signaled to start
Annunciated whenever either emergency stop signal is received from external switch Emergency stop
