PROBLEM
The existing regeneration issue can cause certain C13 Generator Sets XQ350 in certain cases to not perform a high speed regeneration. If soot load builds to 116% +10 min forced idle protection will occur reducing engine speed below rated during which a low speed regeneration will initiate. The resulting lower frequency and voltage can cause damage to electrical loads while the circuit breaker is closed.
