8.2.7 Alarm□ Hysteresis(Alarm□ hysteresis)
Set the interval between alarm output ON and OFF.
If PV is over or below alarm output SV, output turns ON and it sets OFF time by hysteresis
settings.
When input value is changed near SV, alarm output is often. Set hysteresis and it can be prevent
from often alarm output.
Setting range: 0.0 to 9999.9 (Decimal point position is different by the set decimal point
position of input.)
Factory default: 0.0
The below graph is when Alarm□ Type(Alarm□ operation mode) is set as absolute value
upper limit alarm, Alarm□ Value(Alarm□ set value) is set as 200, and Alarm□
Hysteresis(Alarm□ hysteresis) is set as 10.
