| Governor fault | Cannot control speed | Check actuator, controller |
Frequency Errors
أيضًا, frequency is directly related to engine speed. بالإضافة إلى, diesel generator fault codes for frequency indicate التحكم في السرعة problems. خاصة, a 50Hz generator runs at 1500 أو 3000 دورة في الدقيقة. علاوة على ذلك, a 60Hz generator runs at 1800 أو 3600 دورة في الدقيقة. لذلك, frequency problems are actually speed problems.
| Frequency Issue | Speed at 50Hz | Speed at 60Hz | مشكلة |
|---|---|---|---|
| High frequency | Above 1500/3000 | Above 1800/3600 | Overspeed |
| تردد منخفض | أقل 1500/3000 | أقل 1800/3600 | Overload or fuel issue |
| Unstable frequency | Fluctuating | Fluctuating | Governor problem |
What Do Starting System Fault Codes Indicate?
Cranking Failures
Diesel generator fault codes for starting indicate problems with the starter motor or cranking system. خاصة, overcrank codes mean the engine failed to start after the maximum attempt count. بالإضافة إلى, starter relay faults indicate electrical problems. لذلك, check the battery, محرك بداية, and fuel system when starting codes appear.
