No action, the remaining Alarm
parameters are not available.
 Absolute High
(balanced hysteresis)
The alarm energizes when the Process
Value exceeds the alarm value + 1/2 the
hysteresis value.
 Absolute Low
(balanced hysteresis)
The alarm energizes when the Process
Value falls below the alarm value -1/2 the
hysteresis value.
 ^{Absolute High}
The alarm energizes when the Process
(unbalanced hysteresis) Value exceeds the alarm value.
 ^{Absolute Low}
The alarm energizes when the Process
(unbalanced hysteresis) Value falls below the alarm value.
