Natural will dispense after the Color (or Additive) dispense
and will be calculated to assure the most exact percentage
ratio for the selected component. Because the Natural
dispense is larger, this method allows for more exact
ratioing of the one selected critical component.
NOTE: Do not use this feature in combination with *69.
*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.
Use the "CE" key to toggle a component ON or OFF.
When ON, Display will say (C=ON 85).
You may change the 85 by entering a different number.
Too low will just add time. Too high will cause occasional
overshooting.
Press EXIT when done to save new settings.
*86 Press (*,8,6) to select a new "Back Door" password for your
software. Display will say (BDP 00000). Enter 00001 up to
00009 to select one of nine new backdoor passwords. Contact
us for the actual number. If you just want to kill the use
of a backdoor password altogether, just enter a number from
1 to 9, and don't call us. Then no one in you plant will
