readings are always taken and they must be within KDF grams of each other to be
accepted as valid. Readings are taken continuously until two consecutive readings meet
the criteria. This prevents a single accidental bump of the scale from causing a grossly
inaccurate reading. WDF also allows the first digit to determine how long a reading is
taken. A 1 in the first position indicates ½ second per reading. 2 means 1 second, 3
means 1.5 seconds, up to 5 which is 2.5 seconds. The higher this number the slower the
blend rate, but the more reliable the readings.
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 effects 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.
ROC
Allows for adding some ADDITIVE to one of the REGRIND portions
ROC indicates the PERCENT of one REGRIND that will be treated as natural when
ADDITIVE dispenses are calculated. If you feel it is necessary to ADD (or subtract) color
or additive to your regrind, this parameter will automatically see that this is accomplished.
The first digit is 0 to add, 1 to subtract.
The second digit is the REGRIND component number you will be making this adjustment
for.
The last 3 digits indicate the percent of this Regrind component to add
to, or subtract from, the Naturals when computing Additive dispenses.
EXAMPLE: ROC set to (ROC 01020).
The first 0 means add. The 1 is component 1.
The 20 means take 20 % of component 1 (a Regrind) and ADJUST the total of all
NATURAL dispenses upward by this amount. Whatever amount of component 1,
Regrind, is added, 20 percent of this amount will be added to the Natural amounts before
a color calculation is made.
Regrind dispense = 600 grams, Natural portions = 1400 grams.
At 4 percent, if ROC=00000, Color would be 56 grams.
