Troubleshooting
9Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Controller reset | Electromagnetic interference (EMI) | Inspect the distributor cap and rotor for specific features. Replace them if necessary with updated parts. |
| Rough operation | Electromagnetic interference (EMI) | |
| Cooling Fans Cycle at Low Temperatures (48RCL only) | Update the controller with software version 4.05 or higher. | |
| L1-L2 Low Voltage Shutdown during Exercise | Update the controller with software version 4.07 or higher. | |
| Display Errors | Install controller software version | |
| Lack of Communication with Generator RBUS Accessories | An internal failure of a component in the controller can cause this communication problem. | Verify the presence of 12 VDC on the RBUS line terminals PWR and COM. Check connections and then replace the controller assembly if 12 VDC is not present on these terminals. |
| Engine Hunting | A number of factors can result in engine hunting. | Perform the following steps: 1. Disconnect ATS to prevent automatic starting. 2. Confirm under what conditions the generator hunts. 3. Update firmware and install vent tubes on the fuel regulator as described. 4-11. Follow additional troubleshooting steps including checking Engine Speed Gain Adjustment, air intake tube, fuel source setup, fuel pressure, solenoid valve operation, and throttle plate movement. |
| Battery short circuits | Disconnect the battery before generator set installation or maintenance. | |
| Gas fuel leaks | Check the LPG vapor or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6--8 ounces per square inch (10--14 inches water column). Do not operate the generator set in the presence of fuel leaks, fuel accumulation, or sparks. |
