Briggs & Stratton 190839GS Power During Fault Condition, Low Voltage, Engine Fail To Start

Briggs & Stratton Power Products Home Generator System

Owners Manual

Low Voltage

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 overloaded circuits in the transfer switch.

Remedy the problem (you may need to contact your installer or Briggs and Stratton Technical Services for assistance), then reset the Fault Detection system, as described above.

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.When the problem is corrected, reset the Fault Detection system as described above.

Low Frequency

Engine Overspeed

This fault is indicated by 6 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if its 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 Briggs and Stratton Technical Services for assistance.When the problem is corrected, reset the Fault Detection system as described above.

Oil Temperature High

This fault is indicated by seven blinks.The contacts of the temperature switch (Figure 5) are normally open. If the engine 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, 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.When the problem is corrected, reset the Fault Detection system as described above.

This fault is indicated by 5 blinks.This feature protects devices connected to the transfer switch by shutting the generator down if its engine runs slower than the preset limit.

This condition is caused by a failed engine governor or by excessive loads on the transfer switch.To remedy the problem, you may need to contact your installer or Briggs and Stratton Technical Services for assistance.When the problem is corrected, reset the Fault Detection system as described above.

Power During Fault Condition

Whenever the Home Generator System is in an uncorrected fault condition, the automatic transfer switch is reset to UTILITY POWER.This means that when utility power is restored, utility power will be applied to the essential circuit loads.The generator is disconnected from the automatic transfer switch for the duration of any detected fault condition.
