Emerson Process Management 1500 manual 7.5.3Rolling AOC calibration

Configuring the Filling and Dosing Application

Another AOC calibration is recommended:

•If equipment has been replaced or adjusted

•If flow rate has changed significantly

•If fills are consistently missing the target value

7.5.3Rolling AOC calibration

Note: In common use, the first fill may be slightly overfilled because the default compensation factor is 0.2. To prevent this, increase the AOC Coeff value in the Run Filler window (see Figure 8-1). This value must be small enough so that when it is multiplied by the flow rate, the resulting value is less than the fill target.

To enable rolling AOC calibration:

1.Click ProLink > Run Filler. The window shown in Figure 8-1is displayed.

2.Click Start AOC Cal. The AOC Calibration Active light turns red.

3.Begin filling. Do not click Save AOC Cal. The AOC coefficient is recalculated after each fill, and the current value is displayed in the Run Filler window.

At any time, you can click Save AOC Cal. The current AOC coefficient will be saved in the transmitter and used for all overshoot compensation during subsequent fills. In other words, this action changes the AOC calibration method from rolling to standard.
