■Double hold and difference-HI/LO limit comparisons
Double Hold HI/LO Limit and Difference-HI/LO Limit comparisons are made, and respective
judgment results are output externally.
When the Comparison Standard is A
:
The HI/LO Limit comparison result and Difference value-HI/LO Limit comparison result of
hold value A are output together.
- Hold value A HI Limit (HI-A) & Difference value-HI Limit (DF-HI)
ON condition:Hold value A > HI-A Limit, or Difference value > Difference value-HI Limit
OFF condition: Hold value A
≦ HI-A Limit, and Difference value ≦ Difference value-HI Limit
- Hold value A LO Limit (LO-A) & Difference value-LO Limit (DF-LO)
ON condition: Hold value A < LO-A Limit, or Difference value < Difference value-LO Limit
OFF condition: Hold value A ≧ LO-A Limit, and Difference value ≧ Difference value-LO Limit
- HI-B Limit (HI-B)
ON condition: Hold value B > HI-B Limit
OFF condition: Hold value B ≦ HI-B Limit
- LO-B Limit (LO-B)
ON condition: Hold value B < LO-B Limit
OFF condition: Hold value B ≧ LO-B Limit
- OK
ON condition: All of HI-A, LO-A, HI-B, LO-B, DF-HI, and DF-LO are OFF.
OFF condition:
Any of HI-A, LO-A, HI-B, LO-B, DF-HI, and DF-LO is ON.
* The Hysteresis setting is not reflected in the Difference-HI/LO Limit comparison operation.
* If the Comparison Timing condition is not met, the comparison result of the value targeted for the
Comparison Timing turns OFF.
* OK is displayed each on the LCD screen as hold value A, and the difference value are OK and
hold value B is OK.
When the Comparison Standard is B
:
The HI/LO Limit comparison result and Difference value-HI/LO Limit comparison result of
hold value B are output together.
- HI-A Limit (HI-A)
ON condition: Hold value A > HI-A Limit
OFF condition: Hold value A
≦ HI-A Limit
- LO-A Limit (LO-A)
ON condition: Hold value A < LO-A Limit
OFF condition: Hold value A
≧ LO-A Limit
