The alarm energizes when the Process
Value falls below the alarm value -1/2
the hysteresis value.
I
Absolute High
(unbalanced hysteresis)
The alarm energizes when the Process
Value exceeds the alarm value.

Absolute Low
(unbalanced hysteresis)
The alarm energizes when the Process
Value falls below the alarm value.
