Configure AOC using ProLink III

AOC (Automatic Overshoot Compensation) adjusts the timing of the valve close command to minimize
overshoot. The valve close command is sent before the target is reached, to compensate for the time
required for the valve to close completely. AOC is applied to all presets and all batches.
There are three options for AOC:
Compensation Off The transmitter sends the close command when the measured batch total reaches
the configured target.
Fixed The transmitter sends the close command when the measured batch total equals the
Compensation target minus the value configured for Fixed Overshoot Compensation. This value is
Value
configured in the current mass or volume unit, and applies to all presets.
AOC Algorithm The transmitter compares the actual measured amount of each batch to the batch
target, and determines the adjustment by calibrating itself according to an internal
algorithm. You can choose to stop AOC calibration when you are satisfied with the
result, or you can set up rolling (continuous) AOC calibration.
Procedure
• To use the Compensation Off option:
a) Choose Device Tools > Configuration > Batcher.
b) Set AOC Compensation Mode to Compensation Off.
• To use the Fixed Compensation Value option:
a) Choose Device Tools > Configuration > Batcher.
b) Set AOC Compensation Mode to Fixed Compensation Value.
c) Set Fixed Overshoot Compensation to the quantity to be subtracted from the batch target.
Important
Adjust the fixed value:
— Whenever the process changes (e.g., flow rate, process fluid)
— Whenever you change any configuration parameter that can affect flow measurement (e.g., damping)
• To use the AOC Algorithm option:
a) Choose Device Tools > Configuration > Batcher.
b) Set AOC Compensation Mode to AOC Algorithm.
c) Perform AOC calibration.
