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
Regrind Control (12-12 Contollers Only)
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.
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.
The last digit determines the adjustment rate. Zero in the last position means make the full
adjustment immediately. Any value from 1 to 9 indicates the percentage adjustment that
will be made each cycle when the level sensor condition changes. See RHL below for
examples.
RHL LEVEL SENSORS are required for this parameter to work
Use only if you have regrind level sensors fitted
RHL instructs the controller to change the regrind setting of one selected regrind
component if optional level sensors in the regrind hopper indicate high or low conditions.
The component to be changed is determined by the first digit of the ROV parameter above.
If set to all zeros (RHL 00000), then this parameter is ignored.
ROV alters the way RHL is interpreted.
If the last digit of ROV = 0, (ROV x0000), then RHL numbers indicate NEW settings that
are to be run when regrind level is high or low.
