9.2,2. Condition formula for Comparison
Comparison is performed based on the foilowing formula.
state Name Condition Formula
HI (Over) Upper limit value < Display value
OK (GO) Lower limit value ^ Display value ^ Upper limit value
,,,,LO,,iynder)__ Display value < Lower limit value
□ The decimal point is not considered. Example: If the upper limit value is 10.0, input 100.
□ These parameters are stored in the EEPROM, and are not lost even if the AC
power is disconnected,
□ When the display value becomes an over load (positive over), HI (over) is outout.
When the display value becomes an under load (negative over), LO (under) is output.
□ The upper limit value and lower limit value can be set to a negative value.
□ This function compares the upper limit value first.
□ This function does not check the relation of upper limit value and lower limit value.
