KDF is used for load cell calibration weights, WDF for starting tare weight and component dispense
weights.
BER Change only if severe vibration causes problems
BER is the BAILOUT ERROR weight. Dispenses are controlled by very accurate timing. However,
as a precaution, the weigh bin is constantly monitored during each dispense. If bin weight is found
to exceed target weight during the dispense, then a BAILOUT occurs. This ends the dispense
immediately just as if the end of the dispense time period had been reached. This in no way affects
the accuracy of the remainder of the cycle. The dispense is checked and retries will occur if
required.
A bailout does not occur unless target weight is exceeded by the weight given in the BAILOUT
ERROR parameter. This is primarily to prevent vibration from causing a false bailout during very
small dispenses. We set this parameter to a default of 00200 (20 grams or 200 grams). If vibration
is causing false bailouts, then you may want to set a higher value in this parameter.
If the BER parameter has a 1 in the last position, (BER 00201), then a printout will occur of all cycle
data anytime a bailout occurs for any single component. This is helpful if you want to be aware of
occurrences where dispenses significantly exceed target. This will be the same information that
you see when the PRINT flag is on (*54). A printer must be connected.
Weight Limits
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 in order to maintain
proper requested ratios. A recalculated target is not allowed to exceed the value held in the MAX
