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”.
