UnclassifiedSpeed
What This Code Means
Transient performance targets not met; Altered engine transient response; Reduced transient capability; Potential engine over-speeding
Possible Causes
- •Insufficient stabilization time between load steps (less than 180 seconds)
- •Air Fuel Ratio (AFR) control system failed to converge
- •Differences in generator inertia
- •Site-specific environmental or load conditions
- •Wear of components outside of specified tolerances
- •Local generator breaker opens during loaded condition
Suggested Actions
- 1Allow a minimum of 180 seconds between load steps for NOx to return to nominal setting
- 2Tune Engine Governor gains for site conditions
- 3Tune Voltage regulator settings for site conditions
- 4Maintain engine in accordance with guidelines specified in applicable Caterpillar Service Manuals
- 5Ensure engine control algorithm load sensing strategy is active to reset control inputs to rated idle condition
