The PowerStart 0600 is a generator-set controller. It is used on generator sets from Cummins/Onan, including the C12 D6 and PowerStart 0600.
| Code | Meaning | Cause |
|---|---|---|
| 27 | Low AC voltage shutdown | |
| 51 | High Current warning/shutdown | Implementation of the thermal damage curve with instantaneous trip level calculated based on current transformer ratio and application power rating. |
| 59 | High AC voltage shutdown | |
| 81 o | Over frequency shutdown/warning | Generator set is operating at a potentially damaging frequency level. |
| 81 u | Under frequency shutdown | Generator set output frequency cannot be maintained. |
| Symptom | Cause | Remedy |
|---|---|---|
| Battery voltage warning | Status of battery charging system (failure) | |
| Breaker/ATS Switch fail to close warning | When the control signals a ATS switch to close, it will monitor the ATS switch feedback contacts and verifies that switch is closed. If the control does not sense ATS switch closure within an adjustable time period after the close signal, the fail to close warning will be initiated. | |
| Breaker/ATS Switch fail to open warning | When the control signals a ATS switch to open, it will monitor the ATS switch feedback contacts and verifies that switch is opened. If the control does not sense ATS switch opened within an adjustable time period after the open signal, the fail to open warning will be initiated. | |
| Current Imbalance Warning Fault | Issues warning when current imbalance is observed per phase when genset is in running state. | |
| Emergency stop signal is received | The generator set immediately shuts down and cannot run or crank with the E-stop switch engaged. | |
| Fail to start shutdown | The generator set fails to start by the completion of the engine crank sequence. | |
| High AC voltage shutdown (59) | Output voltage on any phase exceeds preset values. | |
| High coolant temperature warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. | |
| Loss of sensing voltage shutdown | Shutdown of generator set will occur on loss of voltage sensing inputs to the control. | |
| Low AC voltage shutdown (27) | Voltage on any phase has dropped below a preset value. | |
| Low coolant temperature warning | Indicates that engine temperature may not be high enough for 1 min. and start or proper load acceptance. | |
| Low lube oil pressure warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. | |
| Over/under frequency sensor overfrequency sensing dropout adjustable from 105-115% of nominal | Dropout adjustable delay from 0.1-15 sec. | |
| Over/under frequency sensor underfrequency sensing pickup and dropout adjustable from 85-100% and 70-85% | Dropout adjustable delay from 0.1-15 sec. | |
| Overvoltage sensor dropout adjustable from 105-135% of nominal | Dropout adjustable delay from 0.5-120 sec. | |
| Sensor failure indication | Logic is provided on the base control to detect analog sensor or interconnecting wiring failures. | |
| Time delay of 0-600 seconds prior to shutdown after signal to stop in normal operation modes | Default for both time delay periods is 0 seconds. | |
| Time delay start and stop (cooldown) configurable for time delay of 0-300 seconds prior to starting after receiving a remote start signal | Control provides retransfer time delays including time delay emergency to normal (0-1800 sec), programmed transition delay (0-600 sec), and time delay engine cooldown (0-3600 sec). | |
| Undervoltage sensor pickup and dropout adjustable from 85-100% and 75-98% | Dropout adjustable delay from 0.1-30 sec. |
