Generator Overfrequency Warning Troubleshooting diagnostic
Tools: multimeter
- Ask operator about cause; if known and repaired, reset genset and resume.
- Compare Generator Overfrequency and Desired Engine Speed Request setpoints to default setpoints.
- EUI engines: verify generator output frequency can be viewed and adjusted on EMCP 3 display.
- MUI engines: adjust frequency with speed potentiometer; if not adjustable, go to step 5.
- Shut down engine; disconnect speed potentiometer from 2301A Governor terminals 11 and 12; measure resistance (0-100 ohms).
- Check speed potentiometer harness open circuit; terminal 11 and 12 to potentiometer resistance should be 5 ohms or less.
- EUI engines: check J1939 Data Link wiring between EMCP 3 and Engine ECM.
- Check three fuses on AC voltage inputs of EMCP 3; they should not be open.
- Open circuit breaker, start engine, measure line-to-line voltage at all three AC input fuses; should equal rated voltage.

- View Generator Underfrequency and Generator Desired Engine Speed Request setpoints; compare against default setpoints.
- If setpoints are not correct, reprogram them, reset the genset and verify.
- EUI engines: verify generator output frequency can be viewed and adjusted from the EMCP 3 Display Screen.
- Adjust generator output frequency to meet site requirements and verify.
- MUI engines: with engine running, adjust output frequency using the speed potentiometer.
- Disconnect speed potentiometer from terminals "11" and "12" on the 2301A Governor; measure its resistance.
- Check the speed potentiometer harness for an open circuit; resistance should be 5 ohms or less.
- EUI engines: check the J1939 Data Link between the EMCP 3 and the Engine ECM.
- Check the three fuses on the AC voltage inputs of the EMCP 3; fuses should not be open.
- Open the circuit breaker or remove load, start and run the genset, measure voltage between all three AC input fuses.

Voltage reconnection
| Voltage | Phase | Connection | Leads | Notes |
|---|---|---|---|---|
| 3-wire delta | Open Delta configuration of external potential transformers (PT) | Allows accurate measurement of power parameters including unbalanced loads and circulating current. Real power phase A, B, C and power factor phase A, B, C can not be determined. Two potential transformers allow maximum accuracy. | ||
| 4-wire wye | Open Delta configuration of external potential transformers (PT) | Results in less accurate measurement of all power parameters when loads are unbalanced and neutral current is present.
