9.2.2. Condition formula for Comparison
Comparison is performed based on the following formula.
State Name Condition Formula
HI (Over) Upper limit value < Display value
OK (GO) Lower limit value Display value Upper limit value
LO (Under) 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.
