Hysteresis area
Menu 6
As you can see the hysteresis is a protected area in which the alarm is not sent,
when the value exceeds the minimum value (MIN) when there is no alarm or the
maximum value (MAX) alarm is active, the minimum value (MIN) alarm is set. To
exit the MIN alarm condition, the value should be equal to the MIN value plus the
value of hysteresis.
Note :
the hysteresis value must be less than ½ referred to distance between the
minimum value (MIN) and maximum value (MAX).
An example of an analog alarm setting, are included in the following section in
