Cummins generator set users have discovered that the unit in use suddenly displays an underspeed fault and shuts down. What exactly is the cause of this malfunction? The technical department of the diesel generator manufacturer answered our question seriously!
The analysis of the reasons for the shutdown of Cummins diesel generator set due to the display of underspeed fault is as follows:
1: Cummins generator set is overloaded, and the load exceeds the rated power of Cummins generator set. The solution is to reduce the load on its unit.
