*82 Press (*,8,2) to produce a precision ratioing of a selected
Additive. Press CE to toggle between (P/R OFF), (P/R 1),
(P/R 2), etc. Only those components already designated as
an ADDITIVE will be displayed.
If precision rationing is selected, the specified additive
(selected by the *82 function) will dispense BEFORE the
Naturals, instead of after. Natural dispenses occur after
the selected additive dispense and are calculated to assure
the most exact percentage ratio for the selected component.
Because the Natural dispenses are larger, this method allows
for more exact ratioing of the one selected critical
component.
*83 Press (*,8,3) to select "Progressive Metering" option.
Progressive Metering allows for more accurate dispenses of
selected components. However, cycle time will be extended
by a few additional seconds.
In normal operation blenders target a dispense of the full
requested amount in one try. This almost always works, and
generally will fall within acceptable upper and lower error
limits. Making the dispense in one try allows for high
throughput rates while still achieving a level of accuracy
acceptable for most processors. When the accuracy of one
particular component is critical, or the process depends on
maintaining a tighter tolerance of this component, customers
may lengthen the blend cycle time slightly to achieve this
higher level of accuracy.
The *83 function is used to turn on the progressive metering
function for a selected component. This sets parameters
which will cause the dispense to occur in several
progressively smaller dispenses. This results in a more
accurate dispense.
The first dispense targets only 85 percent (the default
percentage) of the full required amount. After careful
weighing, each successive dispense targets 50 percent of the
remaining shortage. This continues until the amount
reaches, or is within 1 percent of, the target. In this
manner the software "sneaks up" on the target, providing the
maximum achievable accuracy possible.
When a component is selected and turned ON, the
corresponding PT and RP parameters are set to PT 00085 and
RP 00001.
The keypad sequence:
Press *,8,3. Display will say (COL OFF).
Use the "*" key to walk through all the components.
