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 Configure > Manual Setup > Inputs/Outputs > Batcher > Batcher.
b) Set Compensation Mode to No Compensation.
• To use the Fixed Compensation Value option:
a) Choose Configure > Manual Setup > Inputs/Outputs > Batcher > Batcher.
b) Set Compensation Mode to Fixed Value.
c) Set Fixed AOC Value 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 Configure > Manual Setup > Inputs/Outputs > Batcher > Batcher.
b) Set Compensation Mode to AOC.
c) Perform AOC calibration.
Restriction
You cannot perform AOC calibration using the Field Communicator. AOC calibration requires running
several batches, and you cannot run batches using the Field Communicator.
