3. Increase the FUL parameter. This sets the batch size. Larger batches increase throughput. Depending on the bulk
density of your material, you may be able to increase batch size by 20 to 40 percent.
4. Turn "FAST" on. This causes rapid volumetric "timed" dispenses to occur up to 4 times after each normal gravimetric
dispense.
5. Do not confuse "reserve" with "throughput". If your blender has a temporary problem which results in your process
running out of material before you have time to remedy the problem, your "reserve" is inadequate. Add a surge hopper, or
material level alarms on individual hoppers to prevent these types of problems.
Normal Operating Sequence
This section tells you how the system is supposed to work. If your system is not operating correctly, this description
may help you spot exactly where the system is failing, providing a clue to the problem.
Turn POWER ON:
The current program version date (V=xxxxxT) is displayed for 1 second, followed by the check
sum number (CKS xxxx), followed by a ROM check (ROM OK ), followed by a display of ( 0). The
weight in the weight bin is now displayed. It should be 0 plus or minus several grams. During the
first few minutes of operation, the displayed weight readings may drift slightly as the circuitry
warms up.
BEGIN operation:
The unit will begin to operate if both switches on the left side are UP in the CONTINUE position
and the SENSOR in the mix chamber is UNCOVERED. The sensor must be plugged into the
right side of the controller. If it is not, this has the same effect as the sensor being covered; the
unit will not run.
If the WEIGH BIN DUMP Flap opens and closes repeatedly:
If initial empty bin TARE weight is 100 grams or more, the weigh bin dump valve will operate in an
attempt to empty the bin and bring the starting weight closer to zero. If the bin is empty but the
weight reading is greater than 100 grams then something is wrong. See TESTING the LOAD
CELLS and LOAD CELL CALIBRATION.
If the ALARM flashes:
If the initial TARE weight is below -50 grams the Alarm will flash and the unit will not operate. Go
to TESTING of LOAD CELLS and LOAD CELL CALIBRATION.
The DISPENSE sequence begins:
If initial tare weight is within limits, between -50 and +100, the sequence will begin.
DISPLAY during dispenses:
During all dispenses, the component number and Type letter (R,N,A) will be displayed indicating
which component is being dispensed. The INITIAL display is the tare weight of the bin. This will
not change during the first dispense. After each dispense, the new total weight of the material in
the bin is updated and displayed.
REGRINDS first:
If REGRIND is part of the blend, REGRIND dispenses will occur first in order of size, from the
largest to the smallest. The letter "R" will appear in the display. After these dispenses an
exact weight is taken to determine the space remaining in the weigh bin for the remaining
dispenses. The total bin weight will appear in the display 2 seconds AFTER each dispense
has ended.
NATURALS second:
The NATURAL dispenses occur next in the sequence. They will be dispensed in order of
size, largest to smallest. The letter "N" will appear in the display. The exact weight of all
NATURAL dispensed is now determined for calculating the ADDITIVE dispenses.
