| Symptom | 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. |
| Emergency stop signal is received | The generator set immediately shuts down and cannot run or crank with the E-stop switch engaged. |
| 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. |
| 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. |
| High coolant temperature warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. |
| 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. |
| Low coolant temperature warning | Indicates that engine temperature may not be high enough for 1 min. and start or proper load acceptance. |
| Low lube oil pressure warning/shutdown | Level is pre-set to match the capabilities of the engine used. Control includes time delays to prevent nuisance shutdown signals. |
| 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. |
| Over/under frequency sensor overfrequency sensing dropout adjustable from 105-115% of nominal | Dropout adjustable delay from 0.1-15 sec. |
| Over/under frequency sensor underfrequency sensing pickup and dropout adjustable from 85-100% and 70-85% | Dropout adjustable delay from 0.1-15 sec. |
| Overvoltage sensor dropout adjustable from 105-135% of nominal | Dropout adjustable delay from 0.5-120 sec. |
| Sensor failure indication | Logic is provided on the base control to detect analog sensor or interconnecting wiring failures. |
| Time delay of 0-600 seconds prior to shutdown after signal to stop in normal operation modes | Default for both time delay periods is 0 seconds. |
| Time delay start and stop (cooldown) configurable for time delay of 0-300 seconds prior to starting after receiving a remote start signal | Control provides retransfer time delays including time delay emergency to normal (0-1800 sec), programmed transition delay (0-600 sec), and time delay engine cooldown (0-3600 sec). |
| Undervoltage sensor pickup and dropout adjustable from 85-100% and 75-98% | Dropout adjustable delay from 0.1-30 sec. |
| 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. |
| 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. |
