| 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. |
| Engine has overheated (engine temperature has risen above 230°F/110°C) or coolant level is low | A. Check coolant level and replenish if low. b. Check for possible coolant leakage points and repair if necessary. c. Check for obstructions to cooling airflow and correct as necessary. d. Check for a slipping fan belt and tighten if loose. e. Reset control and restart after locating and correcting problem. Contact an authorized service center if none of the above. |
| Engine oil pressure has dropped to 20 psi (138 kPa) | If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow step 4 procedure. |
| Engine runs and then shuts down, OVERSPEED lamp lights | Contact an authorized service center for service. |
| Engine starts from generator control panel but will not start automatically or from a remote panel (Note: The Run/Stop/Remote switch must be in the Remote position for automatic or remote starting) | Contact an authorized service center for service. |
| Engine will not crank | A. Fault lamp on. Correct fault and reset control. b. 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 is 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. |
| 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. |
| Fault lamp lights but no fault exists. Engine gauges show oil pressure, engine temperature, and frequency (speed) are within normal limits | The monitor board or a sensor may be at fault. Contact an authorized service center. |
| 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. |
| Green RUN lamp does not light following engine startup | Indicates possible Start/Disconnect relay failure. Contact an authorized service center for assistance. |
| HI ENG TEMP lamp lights. Engine shuts down. | Indicates engine temperature has risen to approximately 220°F (104°C) or coolant level is low. If generator is powering non-critical and critical loads and cannot be shut down, use the following: a. Reduce load if possible by turning off non-critical loads. b. Check air inlets and outlets and remove any obstructions to airflow. If engine can be stopped, follow procedure in step 3. |
| 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. |
| LO FUEL lamp lights. Engine continues to run | Indicates diesel fuel supply is running low. Check fuel supply and replenish as required. |
| LO FUEL lamp lights. Engine shuts down and LO OIL PRES lamp lights | Indicates engine has run out of fuel. Check fuel level and replenish as required. |
| LO OIL PRES lamp lights. Engine shuts down | A. Check oil level, lines and filters. b. If oil system is OK but oil level is low, replenish. c. Reset control and restart. Contact an authorized service center if oil pressure is not in the range of 29 to 65 psi (200 to 447 kPa). d. If engine can be stopped, follow procedure in Step 4. |
| 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. |
| No AC output voltage | Field breaker is tripped. Reset breaker. Contact an authorized service center if voltage buildup causes breaker to trip. |
| OVERCRANK lamp lights and engine stops cranking | A. Check for fuel prime, empty fuel tank, fuel leaks, or plugged fuel lines and correct as required. b. Check for dirty fuel filter and replace if necessary (see Maintenance section). c. Check for dirty or plugged air filter and replace if necessary (see Maintenance section). d. Reset the control and restart after correcting the problem. Contact an authorized service center for service if none of the above. |
| SWITCH OFF lamp flashes | Indicates Run/Stop/Remote switch is in the Stop position which will prevent automatic starting if an automatic transfer switch is used. Move the Run/Stop/Remote switch to the Remote position for automatic starting. |
| The O/U VOLTAGE lamp lights | Contact an authorized service center for service. |
| The OVERLOAD lamp lights. Engine shuts down | The line circuit breaker is located in the output box or ATS. If load exceeds generator current rating, the breaker will trip preventing the generator from being overloaded and the genset will shut down. Locate the source of overload and correct as necessary. Manually reset breaker to reconnect the load to the generator. |
| 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. |
