3.10.1 Preact
Preact provides some scale overfill protection on the first draft of a cycle when the upper garner may be full and the
surge of flow on the first draft might be overwhelming. The preact value entered may be exceptionally large and is
the fixed value in effect on every first draft that occurs after pressing
Start or after recovering from a stop by press-
ing Resume . On subsequent fills during the cycle, the preact self learns and makes large auto preact adjustment cor-
rections of 50% whenever the final fill weight is more than 2% of the fill weight preset.
Press the Preact Mode softkey to access that screen. Select a preact option. Press the Preact Mode softkey to toggle
between ON, OFF, and LEARN .
Enter the preact weight by pressing the Preact Weigh t softkey. Press enter to save that selection.
