Integral Indicator Scale Setup
The following five displays are available for integral
indicators: input pressure, % of range, user set scale,
input static pressure*
1
, and % of static pressure
range*
1
. A cycle of up to four displays can be shown
by assigning variables to the parameters at
Disp
select
.

Indicates input pressure in
2.5 to
110% range depending on the
set range (
LRV
and

).
Indicates values depending on the
engineering range (
Engr LRV
and
Engr URV
) with the unit (
Engr Unit
).
Indicates input static pressure with
the indication limits –99999 to 99999.
Reference pressure is factory-set in
absolute.
Indicates input static pressure in –10
to 110% range depending on the
set range (
SP LRV
and
SP URV
).

b. Cyclic Display
In addition to the display set at
Disp Out 1
, displays
can be set at
Disp Out 2
,
Disp Out 3
, and
Disp Out
4
for cyclic display in the order of the parameter
number.
c. Setting Static Pressure Scale
Static pressure can be displayed as a measured input or
as a percentage, independent from the 4-20 mA output
signal for measured pressure or differential pressure.
The
SP setup
parameters under
SP sensor
allow
the setting of the range, unit, and damping time
constant for the static pressure as well as the pressure
management range for PV.
Note that either the high or low pressure side of the
capsule can be selected to monitor the static pressure
by means of the
H/L Select
parameter under
SP
setup
.
