This means that the frequency (engine speed) was very high. This overspeed e-code is for instantaneous overspeed (Hz is over set threshold). Could have come unplugged, become jammed or anything else that may increase engine speed.
Most likely cause is a stepper motor or mixer assembly issue. This means that for 3 seconds, the frequency (engine speed) was 72Hz or above on a 60Hz unit or 60Hz or above on a 50Hz unit (not a US unit). This overspeed e-code is for prolonged overspeed (Hz is over set threshold). Valves are normally a culprit of overcrank alarms. Fuel and maintenance related items should be checked.
The controller has limited the number of starts at 10 to prevent damage to the starter. Overcrank 1101 (This ONLY pertains to 8 & 9kW units) Check to make sure that the fuel supply is on and if on LP gas, the tank is not empty. This is most likely fuel or maintenance related. The controller has verified that the engine is actually cranking, but not starting. Basically this means that the controller is telling the engine to start, but it cannot start for some reason. No error code number is given for this fault. The controller has an internal problem and should be replaced. There is a short description next to each one explaining a possible problem and a solution. After seeing tons of search data for the forums and answering tons of questions both here and on the phone, this chart seems like a helpful idea! The following are some common e-Codes from the Generac Evolution controller that you may see if there is a problem.
