over 3000 grams probably would exceed the volume capacity of the bin
and, therefore, not be accurate. We have set the full batch weight to
2000 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 2000 grams to be too much volume for the bin. Select a lower
total batch weight such as 1500 to ensure that the bin never overflows
of fills completely to the dump valve.
======================================================================
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.
======================================================================
TH and TL
TH and TL are acceptable error limits for TARE WEIGHT.
Before a dispense cycle begins, the software checks to see that the
weigh bin is in place and not already full of material. To do this it
looks at the starting TARE weight.
If Tare weight is below the value of TL, (50 grams), the software
assumes the bin is either missing or hung up on something. In this
case the ALARM sounds.
If Tare weight is above the value of TH (100 grams), the software
assumes material is in the bin. In this case the ALARM sounds and the
weight bin dump flap operates in an attempt to empty the weigh bin.
If you are processing a material that has a tendency to hang up in the
corners of the bin, you may wish to widen the range of acceptable
starting tare weight. Since tare weight is always subtracted from
dispense weights, these errors do not effect accuracy.
======================================================================
PRT (change to get AUTOMATIC printing of material totals)
PRT, when set to any number other then zero, will cause the
processor to output all current material usage totals, at regular time
intervals, to the printer port. The number you enter will dictate the
time interval in minutes. All timing starts from MIDNIGHT. for
example, an entry of 00120 will cause totals to print at 2 AM, 4 AM, 6
AM, etc. Printing always waits until a cycle has just ended. A
setting of 10000 is a special case. This will cause a printout after
every cycle. A printer must be connected. If one is not, the routine
will abort and blending will continue.
