STATUS INDICATORS
Status indicator lights relay conditions of generator function for user or service technician convenience. Illumination of these indicator lights communicate conditions that require generator service but are not severe enough to cause damage if the generator is allowed to operate. Contact a qualified service technician immediately for service if any of the listed lights are lit, even if the generator appears to function normally.
A. LOW BATTERY 
The Low Battery light is lit when the cranking battery voltage falls below 11.0 volts. At this level, the battery begins to lose the ability to consistently start the engine. Causes of low battery voltage may include a failing battery, failed battery charger or failed engine alternator.
B. NOT IN AUTO 
The Not In Auto light is lit whenever the control panel mode switch is not placed in the AUTO position. This light is provided to call attention to this condition since the generator cannot start automatically during a power outage without the switch in the AUTO position. It is normal for this lamp to light when the generator is running with the mode switch in the RUN position, or if the switch is in the OFF position. To turn the light off, move the mode switch to the AUTO position.
H. GENERATOR ON
The Generator On light illuminates when the generators engine is running. This is the only light lit when the generator is supplying power as intended.
FAULTS
Fault lights relay conditions that may cause damage to the generator and/or loads connected to the output of the generator. When any of the listed situations occur while the generator is running, the generator is shut down and the fault light associated with the shutdown cause is lit. Once the light is lit, it remains on until it is cleared by moving the control panel mode switch to the OFF position. If a fault light is lit, determine and correct the cause of the problem before restarting the generator. During generator starting, the controller ignores fault conditions until 15 seconds after the generator starts, then uncleared faults will once again cause the generator to shut off. To determine possible fault causes, refer to the troubleshooting section of this manual or contact a qualified service technician for assistance.
C. OVERCRANK
The Overcrank light is lit if all three 10 second cyclic crank attempts are unsuccessful in starting
the engine. Once the light is on, the generator does not attempt to start until the fault is reset. When the Overcrank light is on , verify fuel is available at the inlet to the unit, then check the condition of the cranking battery.
D. LOW OIL
The Low Oil light turns on and the engine is shut off if the engine oil level falls too low. To avoid engine damage, engine oil pressure is monitored to determine the amount of oil in the engine. When pressure falls below a preset level, a Low Oil fault occurs. Check for proper oil level if the generator shuts down due to a Low Oil alarm.
E. HIGH TEMPERATURE
The High Temperature light illuminates if the temperature of the engine becomes too high. Engine oil temperature is monitored while the engine is active and the engine is shut off to avoid damage if the oil temperature becomes too high. When operating the generator in temperatures above the maximum listed on the nameplate, it is necessary to reduce the load connected to the generator to avoid overheating. If high ambient temperatures or excessive loads are eliminated as possible causes of High Temperature shutdown, check to insure cabinet openings are not restricted by debris.
F. OVERSPEED
The Overspeed light is turned on if the generator engine is running too fast. Electrical output of the generator at high speeds may damage loads connected to the generator output and/or engine failure may occur at excessive speeds. If the generator shuts down on an Overspeed error, seek assistance from a qualified generator service technician.
G. UNDERSPEED
The Underspeed light is turned on if the generator engine is running too slow. Electrical output of the generator at low speeds can damage loads connected to the generator output and/or generator failure may occur due to excessive heating in the generator head. If the generator turns off due to an Underspeed error, check to see that the connected loads do not exceed the nameplate rating of the generator.
