Diagnostics - Generac Power Systems H-100 Operation Manual

This is a typical third Generator Parameters page. It graphically displays the percent of i2t thermal limit currently
attained and the percent of Current limit attained. If either limit is exceeded, an alarm will be set and the generator will
shutdown to protect the alternator. This display will then show "% Temp >Over Limit<" and/or "% Curr >Over Limit<".
On some versions, "Temp" is replaced with "i2t". GenLink can provide more information regarding actual limits
exceeded.
