The Detector is a generator-set controller. It is used on generator sets from Cummins/Onan, including the DFAA, DFAB, DFAC and DFBJ.
Also fitted to: Cummins/Onan D, Cummins/Onan DFLD, Cummins/Onan GGHE/GGHF.
| Code | Meaning | Remedy |
|---|---|---|
| 1 | The OVERSPEED lamp comes on and the engine shuts down. | A. Reset the ECM by pushing the Run-Stop-Remote switch to Stop and the Reset switch to Reset and restart the set, monitoring engine speed. Spec A & B: Readjust the cutout speed if it is lower than specified. Replace the overspeed switch if it cannot be readjusted (see Section 3). Begin Spec C: If engine speed is correct and the set still shuts down, replace the ignition control module. b. Adjust the governor (see Section 8). c. If the governor cannot be adjusted to prevent shutdown due to overspeed, check for binding in the linkage. Repair and adjust the linkage as necessary. d. If the set still shuts down due to overspeed, re-install the magnetic speed pick-up unit to make sure the clearance with the flywheel gear teeth is correct. Replace the speed-pickup unit if output voltage at cranking speed is less than 1.5 VAC. (Intermittent open on magnetic speed pick-up lead can also cause an overspeed condition.) e. Replace the governor controller if the set still shuts down due to overspeed. |

Poor battery cable connections. Clean the battery cable terminals and tighten all connections. c. Discharged or defective battery. Recharge or replace the battery. d. Emergency stop button (if equipped) pushed in. To reset, pull switch out and move Run/Stop/Remote switch to Stop position. Then push test switch to Reset/Lamp position. e. Contact an authorized service center if none of the above. |
| 17 | No AC output voltage. | Field breaker is tripped. Reset breaker. Contact an authorized service center if voltage buildup causes breaker to trip. |
| 18 | RUN or fault lamp(s) does not light when Lamp Test switch is engaged. | Contact an authorized service center for assistance. |
| 19 | Green RUN lamp does not light following engine startup. | Indicates possible Start/Disconnect relay failure. Contact an authorized service center for assistance. |
| 197 | Low Coolant Level | |
| 200 | Indicates engine oil pressure has dropped to an unacceptable level. | If generator is powering critical loads and cannot be shut down, wait until next shutdown period then follow 201 Low Oil Pressure procedure. If engine can be stopped, follow 201 procedure. To check oil pressure, access Oil Pressure menu prior to clearing the fault. |
| 200 | Shutdown lamp lights. | Indicates engine oil pressure has dropped to an unacceptable level. If generator is powering critical loads and cannot be shut down, wait until next shutdown period then follow 201 Low Oil Pressure procedure. If engine can be stopped, follow 201 procedure.
