29. the memory and it will function as intended 2 Step Down Transformer Use On Speed Sensing Cable With Inverter Systems In some applications engine controllers are used on generators where there is no utility connection and inverters are used to provide AC power instead of a utility Inverters can produce harmonics that can cause small AC signals to appear on wires that are near any power lines being fed by the inverter If the generator output wires are located close to a line being powered by an inverter a small AC signal can appear on the generator output lines when the inverter is on This signal can cause the engine controller to react as if the generator 1s running 1f the speed sensing wires are connected to the generator output lines This small AC signal can cause the controller to appear to have a Low Oil Failure when the remote start contacts are closed or the controller is put in the manual test mode The controller may think the generator is already running and immediately check to make sure there is oil pressure Since the engine really hasn t started yet there 1s no oil pressure and the controller sees a low oil fault This is seen as the Oil LED turning on steady even before the engine starts to engage the starter Without this false speed signal the controller will not look for oil pressure until the engine has started to run and the crank disengages if oil verification is disabled Simply installing a small transformer between the ge
