ROC indicates the PERCENT of one REGRIND that will be treated as
natural when ADDITIVE dispenses are calculated. If you feel it is
necessary to ADD (or subtract) color or additive to your regrind, this
parameter will automatically see that this is accomplished.
The first digit is 0 to add, 1 to subtract.
The second digit is the REGRIND component number you will be making
this adjustment for.
The last 3 digits indicate the percent of this Regrind component to add
to, or subtract from, the Naturals when computing Additive dispenses.
EXAMPLE: ROC set to (ROC 01020).
The first 0 means add. The 1 is component 1.
The 20 means take 20 % of component 1 (a Regrind) and ADJUST the total
of all NATURAL dispenses upward by this amount. Whatever amount of
component 1, Regrind, is added, 20 percent of this amount will be added
to the Natural amounts before a color calculation is made.
Regrind dispense = 600 grams, Natural portions = 1400 grams.
At 4 percent, if ROC=00000, Color would be 56 grams.
If ROC=01020; increase Natural by 20 % of 600, (120 grams).
Color is now 4 % of 1520 grams (1400+120), or 61 grams.
In some cases, the addition of pre-colored regrind tends to produce
overall better coloring because of an initial more uniform dispersion
of pigment. In this case you may want to add LESS color to the Natural
portions when Regrind is present. Placing a 1 in the first digit of
the ROC parameter (ROC 10000), will cause a portion of this Regrind
component to be SUBTRACTED from the Natural portions, instead of added.
EXAMPLE: ROC set to (ROC 11020).
The first 1 means subtract. The second 1 selects component 1.
This means take 20 % of component 1, a Regrind, and reduce the NATURAL
portions by this amount. Whatever amount of component 1 is added, 20
percent of this amount will be subtracted from the Natural amounts
before a color calculation is made.
Component 1 dispense = 600 grams, Natural portions = 1400 grams.
At 4 percent, if ROC=00000, Color would be 56 grams.
If ROC=11020; reduce Naturals by 20 % of 600, (120 grams).
Color is now 4 % of 1280 grams (1400-120), or 51 grams.

ROV
ROV and RHL parameters work together. Their combined purpose
is to allow the adjustment of one Regrind component up or down based on
input from one or two lever sensors.
LEVEL SENSORS are required for this parameter to work.
Both ROV and RHL must be set for these parameters to have any effect.
NOTE: The component being controlled is ALWAYS automatically assigned
to the bottom set of thumbwheel switches.
The first digit of the ROV parameter indicates which component is
controlled by the adjustment routine. Only components 1 through 9 may
be controlled.
