DDEC® Protection System
The DDEC® protection system monitors all sensors, electronic components, and recognizes system malfunctions. If a critical fault is detected, a warning indicator will illuminate. The malfunction codes are logged into the control unit's memory.
This system has a stepped-power shutdown sequence and an immediate speed reduction without shutdown feature, either of which can be triggered by a major engine malfunction, such as low oil pressure, high coolant temperature, or low coolant level. Engines equipped with the power down/shutdown option have a Stop Engine Override to allow engine operation for a short period of time. Extending the engine run time during an engine shutdown can cause equipment damage.
