Briggs & Stratton Power Products Home Generator
Operator’s Manual
Low Voltage (Generator)
This fault is indicated by three blinks.This condition is caused by a restriction in the fuel flow, a broken or disconnected signal lead, a failed alternator winding, the control panel circuit breaker is open, or Home Standby Generator is overloaded.
To remedy the problem, contact your local service center.
Engine Fail To Start
This fault is indicated by four blinks.This feature prevents the generator from damaging itself if it continually attempts to start in spite of another problem, such as no fuel supply. Each time the system is directed to start, the unit will crank for 15 seconds, pause for 15 seconds, crank for
15 seconds, pause for 15 seconds, and repeat. If the system does not begin producing electricity after approximately 90 seconds, the unit will stop cranking and the LED will blink.
The most likely cause of this problem is no fuel supply. Check the inside and outside fuel shut off valves to ensure they are fully open. Other causes could be failed spark plug(s), failed engine ignition, or the engine air filter is clogged.You may need to contact your installer for assistance if you can’t remedy these problems.
Low Frequency
This fault is indicated by 5 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if the engine runs slower than the preset limit.
This condition is caused by a failed engine governor or by excessive loads on the generator.To remedy the problem, you may need to contact your installer or local service center for assistance.
Engine Overspeed
This fault is indicated by 6 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if the engine happens to run faster than the preset limit.The overspeed fault is detected as follows:
•If the generator output frequency runs at 72 Hz for five seconds, the generator will shut down.
•If the generator output frequency reaches 75 Hz, the generator will shut down instantly.
This condition is caused by a failed engine governor.To remedy the problem, you should contact your installer or local service center for assistance.
Oil Temperature High
This fault is indicated by seven blinks.The contacts of the temperature switch (Figure 4) are normally open. If the engine oil temperature exceeds approximately 140°C (284°F), the fault is detected and the engine shuts down.
Common causes for this condition include running the unit with all access doors removed, obstructed air inlet or exhaust port, low oil level, or debris in the engine cylinder cooling fins.
To resolve the problem, remove any accumulated debris and obstructions and let the engine cool down. Ensure that the Oil Service door and/or the Control Panel door is installed whenever the unit is running.
