Low Idle Mode (LIM)

The intent of this mode is to run the genset at lower than normal speed when the genset is not
connected to external loads. This will reduce overall noise.
While operating in this mode, the controller will only take defined actions on critical faults (Over voltage,
Over frequency, Over current, Over temperature, LOP) and will ignore non-critical faults.
Start command from key pad = 1
And No Warning / Electrical Trip / Shutdown present = 1
Stop input from
