9-6-3. Hysteresis on comparator
The comparator S1, S2, S3 and S4 in the instrument can set hysteresis for prevention from chattering
at output relay.
Hysteresis can be used by the combined of data width and time width. Moreover, effective direction for
hysteresis can be selected from either [OFF delay] or [ON delay].
These selections can be made in Function mode. (Related are F-24, F-25 and F-26).
Default is set to hysteresis [OFF].
Depending on the setting of comparator hysteresis, ON/OFF condition for each output way differ. It
wrong mode is selected, ON/OFF condition for each output become inadequate and it may cause an
unexpected accident due to malfunction on peripheral instruments, so care should be taken fully.
As for the example of S1, the operation of judgment display section when the hysteresis on
comparator is set, will be shown as follows
