Note:
That PV and PRV fields are populated.
Check all XCell ATF® Device connections.
Press START.
Once the system begins to cycle, Note the following:
•
The deviation of Actual Flow from Set Flow. The deviation between the two should be small
following few cycles, the Actual and Set Flows should be similar.
Note:
If in P-Flow block, Actual Cycle Time field is flashing Orange or Red; the same for the E-Flow
block, Actual Cycle Time field. If not flashing, the system is functioning properly. If flashing
remains, stop the controller, and recheck all entries and connections than restart. If problem
persists, check the following:
a.
The ∆P between
PRV1-P2 should be greater than
P-Pressure Offset
and
∆
P between
PRV2-P2 should be less than
E-Pressure Offset
. If not, manually lower PV in small
increments.
b.
Flow is too rapid- A flow that is too rapid during the exhaust cycle can be readily
detected on the P2 trend by a rapid decline in pressure following a stable pressure
profile. (The pump exhausts too rapidly followed by a rapid pressure drop). Decrease
PV2 or PRV2 to decrease flow as a corrective measure.
•
Select the P2 trend in the Main screen and observe P2 profile, The P-Pressure Offset and the
E-Pressure Offset should be apparent.
Any adjustments in P2 trend on the Main screen are performed from the P2 Trend
screens.

Examples
The XCell ATF® Device process control settings will depend on the process requirements. Each user
or process may have its own unique requirements. Hopefully, the example provides a guideline, to
assist the users, in selecting and optimizing operating conditions.
