Procedures
1Circuit breaker catalog number lookup operation
⚠ If the first 3 letters are PJP, start the search with PJ only.
⚠ If the catalog number starts with N, skip the N and begin the search with the second letter.
- Locate the circuit breaker feature code or part number.
- Use the charts to find the corresponding manufacturer circuit breaker catalog number.
- Use the first letter of the catalog number to determine the breaker frame (if first letter is N, use the second letter).
- Follow the corresponding website link to find the breaker catalog number description.
- Search the catalog using the first 3 letters and first 5 numbers of the breaker catalog number.

Troubleshooting
6Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Engine does not crank in manual mode (no fault message) — Engine will not start | No power supplied to control. (Control Alive indicator on Base board is not flashing.) | Poor battery cable connections. Clean the battery cable terminals and tighten all connections. |
| Engine does not crank in manual mode (no fault message) — Engine will not start | Base board not properly calibrated or corrupt calibration. (Control Alive indicator flashes every 1/2 second.) | Confirm that the installed calibration part number matches the serial plate information. Re-enter calibration file if necessary. (When properly installed, Control Alive indicator flashes every second.) |
| Engine does not crank in manual mode (no fault message) — Engine will not start | The Emergency Stop switch or wiring is defective. | With Emergency Stop push button not activated, remove connector P1 and check for continuity between P1-1 (ESTOP-NC-2) and P1-2 (ESTOP-NC-1). (If circuit is open, the control will detect a local E-Stop condition but will not display the E-Stop condition.) If circuit is open, isolate to Emergency Stop switch and wiring. If there is continuity, go to next step. |
| Engine does not crank in manual mode (no fault message) — Engine will not start | The Manual input is not getting from the Manual select switch (S12) to the Base board indicating that S12, Base board or the harness is bad. | With S12 in Manual, remove connector P1 from the Base board and check for continuity from P1-6 (MAN) to P1-8 (GND). If no continuity, isolate to switch and wiring. If there is continuity, go to next step. |
| Engine does not crank in manual mode (no fault message) — Engine will not start | The Manual Run/Stop button, harness or the Base board is bad. | Remove connector P3 from the Base board and check for continuity from P3-9 (MAN RUN/STOP) to P3-10 (GND). If no continuity when pressing the Manual Run/Stop button, replace front membrane panel. If there is continuity (200 ohms or less), the Base board is bad. |
| Engine does not crank in remote mode (no fault message) — Engine will not start in remote mode, but starts in manual mode | The remote start switch or customer wiring is faulty. | Reset the control. Attempt to start, and check for ground at TB1-1. If ground level is not present, isolate to the remote switch or customer wiring. Repair as necessary. If ground is present, go to next step. |
