Example: RHL is set to 90 and 10 percent (RHL 09010).
ROV is set to zero, (ROV 00000).
The "Regrind" thumbwheel switch is set to 25 percent (025).
The Software logic is as follows:
If material level is high, above the high sensor,
the HIGH sensor is COVERED, (returns NO signal);
Regrind runs at the HIGH setting; 90 percent.
If material level is in the middle, between sensors,
the High sensor is NOT covered, (returns a signal),
the LOW sensor IS covered, (returns NO signal),
Regrind runs at the THUMBWHEEL SETTING; 25 percent.
If material level is low, below the low sensor,
BOTH sensors are NOT covered, (both return a signal),
Regrind runs at the LOW setting; 10 percent.
IF ROV equals 1 to 9 (ROV 00001 to ROV 00009):
All the same rules given above apply, except that the thumbwheel switch
regrind setting does not jump in one step to a new setting, but,
instead, moves slowly to the new setting which acts as a limit. The
usage adjustment is made each cycle by the amount specified by the ROV
parameter.
Example: RHL is set to 10 and 90 percent (RHL 09010).
ROV is set to 3 (ROV 00003).
The "Regrind" thumbwheel switch is set to 25 percent (025).
The Software logic is as follows:
If material level rises, goes above the high sensor,
the HIGH sensor is COVERED,
Regrind usage will increase 3 percent each cycle up to a high
limit of 90 percent.
If material level is in the middle, between sensors,
the HIGH sensor is NOT covered,
the LOW sensor IS covered,
Regrind usage will change 3 percent each cycle, moving back
toward the THUMBWHEEL SETTING of 25 percent.
If material level drops below the low sensor,
BOTH sensors are NOT covered,
Regrind usage will decrease 3 percent each cycle down to a low
limit of 10 percent.

FUL (change for extremely light or heavy material)
FUL is the full batch weight in GRAMS set at the factory to 2000
grams. The criteria for this number is to not exceed the volume
capacity of the weigh bin and to not exceed the load cell capacity.
Each load cell is rated for 3000 grams. Total load capacity is 6000
grams. The weigh bin, when empty, weighs about 1200 grams, leaving a
net capacity of 4800 grams for weighing material. However, a dispense
