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”.
