**Typical Holdback Settings:

Percent Holdback - 25

Minimum Holdback - 50 Gallons

Partial Valve Position - 50

**Percent Holdback and Minimum Holdback work by reserving carrier for rinsing and getting all the product to the destination. The Mixmate takes whichever is larger. If you get a message of "Carrier May Run Out", the Mixmate will only run the products until all of them are complete, then finish with carrier.

Example 1:

You have 1000 gallons of carrier and 200 gallons of product getting blended. The minimum holdback is 50 gallons, the calculated percent holdback is 250 gallons. In this example the Mixmate would stop the carrier flow at 750 gallons if not all the products are complete.

Example 2:

You have 100 gallons of carrier and 20 gallons of product getting blended. The minimum holdback is 50 gallons, and the calculated percent holdback is 25 gallons. In this example the Mixmate would stop the carrier flow at 50 gallons+Rinse/Prefill Amounts if not all the products are complete.

**Partial Valve Position is how far open the carrier valve is while adding products. The more open the carrier valve, the slower the product will flow, and the faster holdback will be reached.  The Minimum is 30 so there is some carrier flowing with product, unless holdback has been reached.
