| Symptom | Cause | Remedy |
|---|---|---|
| Batteries can explode | Do not dispose of the battery in a fire, because it is capable of exploding. Do not open or mutilate the battery. Do not charge frozen batteries. Batteries present the risk of high short circuit current when servicing the generator set: remove watches, rings, or other metal objects; use tools with insulated handles. | |
| Dizziness | IF YOU OR ANYONE ELSE EXPERIENCEANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the unit and do not operate until it has been inspected and repaired. | |
| Equipment damage due to wrong calibration file | Do not swap Baseboards from another genset model and only use the calibration file shown on the nameplate. | |
| Exhaust gases are deadly | Provide an adequate exhaust system to properly expel discharged gases away from enclosed or sheltered areas, and areas where individuals are likely to congregate. Visually and audibly inspect the exhaust system daily for leaks per the maintenance schedule. Ensure that exhaust manifolds are secured and not warped. Do not use exhaust gases to heat a compartment. Make sure the unit is well ventilated. | |
| Features not available for troubleshooting base board | Confirm that the feature is installed and enabled prior to trouble-shooting the base board for symptoms related to a feature. | |
| Fuel contact with hot engine or exhaust | Do not permit any flame, cigarette, pilot light, spark, arcing equipment, or other ignition source near the generator set or fuel tank. Fuel lines must be adequately secured and free of leaks. Use an approved flexible line for fuel connection at the engine. Do not use copper piping on flexible lines as it will become brittle if continuously vibrated or repeatedly bent. Ensure all fuel supplies have a positive shutoff valve. | |
| Inability to Think Coherently | IF YOU OR ANYONE ELSE EXPERIENCEANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the unit and do not operate until it has been inspected and repaired. | |
| Increase in load or higher ambient temperature may cause High Coolant Temp (1) shutdown. | Review code 1 correction list for other possible causes. | |
| L not start in remote mode, but starts in manual mode. | The remote start switch or configurable wiring is faulty. | Reset the control. Attempt to start, and check for ground at TB1-11. If ground level is not present, isolate to the remote switch or configurable wiring. Repair as necessary. If ground is present, go to next step. |
| Low oil pressure or high coolant temperature | The control (with graphical display) will light a yellow Warning lamp or a red Shutdown lamp and display a message on the graphical display. A control without the graphical display indicates a shutdown condition by intermittent flashing of the status indicator. | |
| Muscular Twitching | IF YOU OR ANYONE ELSE EXPERIENCEANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the unit and do not operate until it has been inspected and repaired. | |
| Output voltage on any phase exceeds pre-set values. | Values adjustable from 105-125% of nominal voltage, with time delay adjustable from 1-10 seconds. Default value is 110% for 5 seconds. | |
| Shutdown condition | Make sure that parameter adjustments and time delays, related to the fault condition, have been appropriately set for the application. It may be necessary to write the initial capture file to the device or update the calibration file. | |
| Shutdown or unexpected start-up | Press the button to switch to the Off mode. Turnoff or remove AC power from the battery charger. Remove the negative (–) battery cable from the generator set starting battery. | |
| The menu display Auto button, harness or the Base board is bad. | Check for continuity between P11-16 (AUTO) to P11-8 (GND). If no continuity when pressing the menu display Auto button, isolate to front membrane panel or wiring harness. If there is continuity, the Base board is bad. | |
| Unexpected start-up or failure to crank | Remote input | Verify that the remote input is not causing the symptom or isolate the control from these inputs before troubleshooting the control. |
| Voltage on any phase has dropped below a preset value. | Adjustable over a range of 50-95% of voltage, time delay 2-20 seconds. Default value is 90% for 5 seconds. | |
| Vomiting | IF YOU OR ANYONE ELSE EXPERIENCEANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the unit and do not operate until it has been inspected and repaired. | |
| Warning or shutdown by lighting the appropriate LED | The associated fault symbol/text and fault code will also be displayed on the digital display. The nature of the fault and time of occurrence are logged in the control. | |
| Weakness and Sleepiness | IF YOU OR ANYONE ELSE EXPERIENCEANY OF THESE SYMPTOMS, GET OUT INTO THE FRESH AIR IMMEDIATELY. If symptoms persist, seek medical attention. Shut down the unit and do not operate until it has been inspected and repaired. |
