Using the Filling and Dosing Application
Table
Display/Control | Description | |
|
|
|
Fill Statistics | Fill Total Average | Displays the calculated average of all fill totals since fill statistics were reset. |
|
|
|
| Fill Total Variance | Displays the calculated variance of all fill totals since fill statistics were reset. |
|
|
|
| Reset Fill Statistics | Resets fill total average and fill total variance to zero. |
|
|
|
Fill Data | Fill Time | Displays the number of seconds that have elapsed in the current fill. Seconds |
|
| that the fill was paused are not included in the fill time value. |
|
|
|
| Fill Count | Displays the number of fills that have been performed since fill statistics were |
|
| reset. Only completed fills are counted; fills that were ended before the target |
|
| was reached are not included in this total. The maximum number is 65535; after |
|
| that number has been reached, counting resumes with 1. |
|
|
|
| Reset Fill Count | Resets the fill counter to zero. |

(1)This field displays the result of AOC calibration. If you reset it manually, AOC calibration data is lost. Typically, the only reason to set it manually is to prevent overfill on the first few fills. See Section 7.5.
(2)Applicable only when AOC Algorithm is set to Underfill.
Table 8-2 Fill Status fields
Status LED | Description |
|
|
Max Fill Time Exceeded | The current fill has exceeded the current setting for Max Fill Time. The fill is aborted. |
|
|
Filling In Progress | A fill is currently being performed. |
|
|
Cleaning In Progress | The Start Clean function has been activated, and all valves assigned to transmitter |
| outputs are open (except purge valve) |
|
|
Purge In Progress | A purge has been started, either automatically or manually. |
|
|
Purge Delay Phase | An automatic purge cycle is in progress, and is currently in the delay period between |
| the completion of the fill and the start of the purge. |
|
|
Primary Valve | The primary valve is open. If a |
| valve is either open or closed partial. |
|
|
Secondary Valve | The secondary valve is open. |
|
|
Start Not Okay | One or more conditions required to start a fill are not met. |
|
|
AOC Flow Rate Too High | The last measured flow rate is too large to allow the fill to start. In other words, the AOC |
| coefficient, compensated for the flow rate, specifies that the valve close command |
| should be issued before the fill has begun. This can happen if the flow rate has |
| increased significantly with no corresponding change in the AOC coefficient. AOC |
| calibration is recommended. To adjust the AOC value, you can use the Override |
| Blocked Start function to run a fill without AOC (see Table |
|
|
AOC Calibration Active | AOC calibration is in progress. |

8.3.2Using a discrete input
If a discrete input is assigned to a fill control function, the function is triggered when the discrete input is in an ON state.
Table
1.Ensure that Channel C is configured as a discrete input (see Section 4.3).
2.Open the ProLink II Configuration window and click on the Discrete IO tab. The panel shown in Figure
3.Select the fill control function to be triggered. Fill control functions are listed and defined in Table
