PARAMETER MENU
Enter the setpoint (alarm output) to be programmed. The  in the following
parameters will reflect the chosen setpoint number. After the chosen setpoint is
completely programmed, the display will return to
 
. Repeat step for
each setpoint to be programmed. The

chosen at

will return to
 
.
The number of setpoints available is setpoint output card dependent.

 = Setpoint always off, (returns to SPSEL NO)
 = Absolute high, with balanced hysteresis
 = Absolute low, with balanced hysteresis
 = Absolute high, with unbalanced hysteresis
 = Absolute low, with unbalanced hysteresis
 = Deviation high, with unbalanced hysteresis *
 = Deviation low, with unbalanced hysteresis *
 = Outside band, with unbalanced hysteresis *
 = Lower Totalizer absolute high, unbalance hysteresis**
 = Upper Totalizer absolute high, unbalance hysteresis**
* 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

allows setpoints to function off of the
lower 5 digits of the Totalizer. The upper Totalizer action

allows
setpoints to function off of the upper 4 digits of the Totalizer. To obtain
absolute low alarms for the Totalizer, program the

or

output
logic as reverse.
Enter the action for the selected setpoint (alarm output). See Setpoint Alarm
Figures for a visual detail of each action.

For maximum input frequency, unused Setpoints should be configured for

action. The setpoint assignment and the setpoint action determine certain
setpoint feature availability.
