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 Autoweigh 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
in order to maintain proper requested ratios. A recalculated target is
not allowed to exceed the value held in the MAX parameter.
If you change the FUL parameter, the MAX parameter will automatically
be set to a value 50 percent higher then the FUL setting.
DISPENSE STATION CONFIGURATION.
This controller can be configured to operate as a dispense station
(model WSD). This is generally done when exact weights of material or
blend are required to place into a process, such as rotational molding.
In this configuration, the thumbwheel switches tell the controller how
much weight to dispense in pounds (or kilos). The FUL parameter is set
to 00001 or 00002 for direct reading of the top thumbwheel switch; or
optionally, for recipe reading of the second thumbwheel switch.
When dispense weight you request exceeds the amount specified in
the MAX parameter, the unit will automatically make multiple dispenses
that will add up to the requested amount.
