ALARM ACTION FIGURES
Note: Hys in the above figures refers to the Alarm Hysteresis.
AVAILABLE ALARM ACTIONS
 None
No action, the remaining Alarm
parameters are not available.
I
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.
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.
I Deviation High
Alarm 1 and 2 value tracks the
Setpoint value
