Menu System Details
P1.00
: Process Variable –These values are read-only and are meant for diagnostic purposes.
 P1.10
: Inlet Pressure – Line Pressure measured by the high pressure sensor; the
value is based on the unit set in
P2.20
.
 P1.20:
Gas Temperature – Line Temperature; the value is based on the unit set in
P2.30.
 P1.30
: Differential Pressure – Difference in pressure measured between the high and
low pressure sensors; the value is based on the unit set in
P2.20.
 P1.40
: Revision Information – For internal use only.
 P1.50
: Diagnostic Readings – For internal use only.
P2.00
: Process Options – These values are modifiable and change how the user views the flow
rate and process variables.
 P2.10
: Flow Units – Unit of flow rate displayed.
 P2.20
: Pressure Units – Unit of pressure displayed.
 P2.30
: Temperature Units – Unit of temperature displayed.
 P2.40
: Display Average – Increasing this value will increase the average of the flow
rate being displayed on the main screen (range for this value is 1 to 255).
P3.00
: User Alarms – Values are modifiable and allow the user to set custom high and low
flow alarms as well as low pressure alarms in addition to the factory low and high pressure
alarms.
 P3.10
: Low Flow Alarm Limit – Triggers an alarm if the flow drops below the
programmed value (0 = alarm not set).
 P3.20
: High Flow Alarm Limit – Triggers an alarm if the flow increases above the
programmed value (0 = alarm not set).
 P3.30
: Low Pressure Alarm Limit – Triggers an alarm if the supply pressure drops
below the programmed value (0 = alarm not set).
NOTE:
Factory low and high pressure alarms are not viewable or editable.
 P3.40
: Deviation Alarm – Triggers an alarm after 60 seconds if the flow PV deviates
from the flow SP more than the defined deviation (0 = alarm not set).

P3.50
: Factory Alarm Disable – Disables three preset factory alarms given in
P3.51
–
Under Pressure
, P3.52
– Valve Shut
,
and
P3.53
– Max Opening (on = alarm is
disabled).
