Operation of Digi−Switch interface S1, S2, S3 and S4
Optional comparator S1, S2, S3 and S4 each can select whichever operation of “Open collector
ON at greater than or equal to set value” or “Open collector ON at less than or equal to set
value”. These selections can be performed in Function mode.(Related Function FUNC−37).
As for default, “Open collector ON at greater than or equal to set value” has selected for every
S1, S2, S3 and S4.
Warning ● ON/OFF condition for each open collector output may differ
depending on the operational selection of comparator. If wrong
operation is selected, ON/OFF condition for each open collector
output becomes inadequate, it causes an unexpected trouble due to
malfunction in peripheral equipments, so care should be taken.
Operation at judgement display section and contact output at open collector will be shown
below as S1 for example. Same operation can be provided as S2, S3 and S4.
