Setpoint Alarm Figures
With reverse output logic
* Deviation and band action setpoints are relative to the value of setpoint 1.
It is not possible to configure setpoint 1 as deviation or band actions. It is
possible to use setpoint 1 for an absolute action, while its value is being used
for deviation or band.
** The lower Totalizer action
lower 5 digits of the Totalizer. The upper Totalizer action
setpoints to function off of the upper 4 digits of the Totalizer. To obtain
absolute low alarms for the Totalizer, program the
logic as reverse.

This is also for Totalizer alarms:

Enter desired setpoint alarm value. These setpoint values can
also be entered in the Display Mode during Program Lock-

Module 3. When a setpoint is programmed as deviation or
band acting, the associated output tracks
The value entered is the offset, or difference from
Enter desired hysteresis value. See Setpoint Alarm Figures
for visual explanation of how setpoint alarm actions (balance
and unbalance) are affected by the hysteresis. When the
setpoint is a control output, usually balance hysteresis is
used. For alarm applications, usually unbalanced hysteresis
is used. For unbalanced hysteresis modes, the hysteresis
functions on the low side for high acting setpoints and
functions on the high side for low acting setpoints.
Note: Hysteresis eliminates output chatter at the switch
point,
triggering during process transient events.
