level after a valve position change is ordered by the
MODEL 2500. When the variable is OFF, no
verification is performed.
The verify level variable specifies the cutoff value
for differential pressure across a tube set to be used
in verifying a valve position change. The default
value of this variable is 2.
The control number (#) variable displays the
number of the tube assigned as the current control
tube.
Differential pressure name is the analog input variable
with a value that represents the current differential
pressure transmitted.
Low differential pressure switchpoint (expressed in
engineering units) across a tube when the valve
controlling the tube is closed. The default value for this
variable is 2.
High differential pressure switchpoint (expressed in
engineering units) across a tube when the valve
controlling the tube is opened. The default value for this
variable is 98.
Operational status of the tube being displayed (i.e.,
enabled, disabled, fault).
