NOTE:
Underfrequency sensing and/or Overfrequency sensing functions
may be programmed into the ATS Controller through the “Option
Program Key”. In the case which both “Uf” and Of” Sensing
functions are activated, the same DIP switch settings will be
applied to both functions. Two equivalent sizes of sensing
hysteresises will be assigned to below and above the system
line frequency respectively.
