The set value is rated voltage percentage.
The controller detects it while gen-set
prepares to take the load, if voltage is less
than the on-load voltage, gen-set will not
enter normal operation period.
Provide standard for judging over/under
frequency and on-load frequency.
The set value is rated frequency percentage.
The controller detects it while genset
