Feed Factor Filter

This filter allows you to set the number of snapshots that the FIFO page looks at to find the average deviation. Making this number bigger will cause the feeder to make changes slowly, and decreasing the number will make changes faster. You may want to make this number smaller on a feeder with a low feed rate.

Steady Feed Factor

This is the parameter that sets the percent deviation allowed for the feeder to give a stable flag. The lower the percentage the more accurate the feed. With hard to feed materials or materials that vary in bulk density you may have to increase this number. Also if a lot of vibration is occurring that cannot be resolved you may have to increase this.

Max WTP/RPM

This is the maximum weight through put per RPM allowed. This is settable in case you have a very large auger that you are trying to run at a low feed rate. This will help to keep the auger from making rapid adjustments.

Re-fill Percentage

This is the level the hopper will go down to before re-filling.

Learn Percentage

This is the size of the snapshot previously mentioned. Increasing this gives you better stability with materials that very in bulk density or do not flow consistently. Decreasing this gives you faster updates on the FIFO page for materials that are relatively uniform.

Summary

When adjusting the above parameters you will want to look at the FIFO page and analyze the information given. You should be able to determine from the percent deviation what changes to make. For example if an additive takes a long time to give a steady flag you may want to lower the Feed Factor Filter or Lower the learn percentage. When making changes do make them one at a time and observe the FIFO page for results. Another common example is you are running regrind through a feeder and your not getting a steady flag because your percent deviation is too high. You may want to increase the Steady Feed Factor or you could increase the Learn Percentage. A larger Learn Percentage is usually more stable than a small percentage.
