online help.
Atmospheric pressure
Enter a value (KPaa or psia) within the range [30.0, 108.40 KPaa]
This data point is only applicable when the input pressure unit is
specified as gage.
Fixed pressure
Enter the flow-condition pressure (KPag or psig if gage, KPaa or psia if
absolute) within the range [0, 280e3 KPag or KPaa].
Pressure alarm, Low limit
Enter a value (KPag or psig if gage, KPaa or psia if absolute) within the
range [0, 280e3 KPag or KPaa]. An alarm is generated when the pressure
is at or below this limit value.
Pressure alarm, High limit
Enter a value (KPag or psig if gage, KPaa or psia if absolute) within the
range [0, 280e3 KPag or KPaa]. An alarm is generated when the pressure
is at or above this limit value.
Alarm Selection
The Alarm selection determines what value to use while a live input is in
alarm. This value is common with the pressure Alarm selection so when
one is changed, the other will change to match.
Choose Last good value or Fixed value
