What should I do if the diesel engine is stopped due to overspeed failure?
1. Check whether the indication of the tachometer is abnormal
2. For the mechanical speed control system, check whether the throttle lever is flexible and ensure correct adjustment
3. For the electronic speed control system, check whether the throttle lever is flexible, check whether the actuator operates correctly, and ensure that the EPG is adjusted correctly
4. Recalibrate and adjust the overspeed protection limit
5. After troubleshooting, reset the alarm signal on the control screen
12. Number of phases/wiring: three-phase four-wire/Y-type winding
13. Frequency adjustment rate (%): ≤±0.5 (steady state) +10～-7 (transient)
14. Voltage regulation rate (%): ≤±0.5 (steady state) +20～-15 (transient)
15. Frequency volatility (%): ≤±0.5
16. Voltage fluctuation rate (%): ≤±0.5
