IF ROV equals 1 to 9 (ROV 10001 to ROV 10009):
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 last digit is set to 3 (ROV 10003).
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 only for extremely fluffy or heavy material
FUL is the full batch weight in GRAMS set at the factory to 1000, 2000, 4000, 9000, or
18000 grams, depending on model. The criteria for this number is to not exceed the
volume capacity of the weigh bin and to not exceed the load cell capacity. On a 9000 gram
system, load cells are rated for 10,000 grams each. Total load capacity is 20,000 grams.
The weigh bin, when empty, weighs about 2400 grams, leaving a net capacity of 17,600
grams for weighing material. However, a dispense over 13,000 grams probably would
exceed the volume capacity of the bin. We have set the full batch weight to 9000 grams
which we considered a conservative full batch weight. Higher batch weights will increase
maximum throughput rates.
If your Regrind is very fluffy and you use a lot of it, you may find 9000 grams to be too
much volume for the bin. Select a lower total batch weight such as 7000 to ensure that the
bin never overflows or fills completely to the dump valve.
DISPENSE STATION CONFIGURATION.
When this controller is used on a dispensing system (Model WSD; not a Weigh Scale
Blender) where you may wish to frequently change the dispense weight of each batch, this
parameter acts as a flag to allow that mode of operation. When FUL is set to 00001, the
controller will read the top thumbwheel switches as the full batch weight, in pounds from
00.1 to 99.9, and will target that weight for the batch. When set to 00002 it will read the
switch as kilograms (00.1 to 99.9).
See "MAX", next, for more information.
MAX
Set automatically if FUL parameter is changed
MAX is the maximum gram weight, which the software will allow as a target for dispensing.
The initial Full weight target is set by the FUL parameter. As dispenses progress, an over
dispense of one component may cause a new target to be calculated for future dispenses
