Internal Electrical Schematics

Switch Output mode

  • Note 1. In the Separate Mode, setting 1 corresponds to SW1, and Setting 2 corresponds to SW2.
  • Note 2. In the Window Comparator Mode, the minimum value for SW1 and SW2 corresponds to Setting 1 and the maximum value corresponds to Setting 2.
  • Note 3. It becomes only “SW1” for one switch output specification. In that cace, it displays it in the switch operation mode in order of “S-1”“S-3”“C-5”“C-7”.
