The last number (22) is the CYCLE count, a convenient way to keep pages of data in order, like page numbers.
Optional
"BAILOUT" line:
------------ ------------ ------------ ------------ -----
232
A 4th data line (not shown in the beginning example) will print if any single dispense goes past its target weight by a certain value,
this value set by the BER parameter, normally 200 grams. The example line shown here would indicate component 3 overshoot
the target weight after dispensing for only 232 interrupts.
Bailouts are designed to prevent overflows of material when initial software settings, at start up, are entirely inappropriate for the
metering device. A larger then normal error correction will occur after a bailout. Bailouts errors at any time other then startup,
usually indicate either very poor flowing material, or excessive vibration. When a bailout occurs the dispense stops immediately for
a weight reading. Using this information, the cycle then continues normally.
Troubleshooting with the *54 Printout
TOTAL BATCH WEIGHT : (DATA line 1)
Check the TOTAL batch weight, (DATA line 3), to confirm the blender model. 2000 grams indicates 200 series model. 400, 1000,
and 2000 gram totals indicate models that use 3 K load cells, which means output information is in 1/10's of grams. 4000, 9000,
and 18000 gram totals indicate larger blenders that report information in full grams. Since some numbers in the printout do not
include the decimal point, you will want to know if you are reading full grams or tenths of grams.
TARE WEIGHT : (DATA line 2)
In DATA line 2, tear weights should be consistently within a few grams of each other from cycle to cycle. Large variations in the
tare weight numbers may indicate excessive vibration, some mechanical interference with the weigh bin, or a faulty circuit board.
Tare weights above or below zero are not a problem as long as they are consistently similar from cycle to cycle. When problems
are present, tare numbers may vary by up to 50 grams. Variations of 2 or 3 grams are not a problem.
RETRIES : (DATA line 3 and 1, FIRST and FINAL dispense)
When FIRST time dispense, (DATA line 3), does not equal FINAL dispense, (DATA line 1), one or more retries have occurred.
Retries are evidence of a problem that will also cause percentage errors.
Retries may indicate possible problems; perhaps the hopper ran out of material, or the flow rate is so erratic that the first dispense
was short for no good reason. Parameters _RT and _RP determine what shortage error is necessary to force a retry.
FLOW RATE NUMBERS : (DATA line 2)
Check the RATE numbers, (DATA line 2), to determine each dispense device.
In the example above:
In the component 1 column, 18224 and 976 translates to 1822.4 grams in 4 seconds (244 interrupts = 1 sec). This is 455.6 grams
per second, typical for a regrind flowing through 3" round or 2"x3" dispense valves.
In the component 2 column, 19993 and 488 indicate 1999.3 grams in 2 seconds, or 999.6 grams per second flow rate. This is a
heavy natural material, not polyethylene. Perhaps Lexan or a glass filled material.
In the component 3 column, 12973 and 31232 indicate 1297.3 grams per 31232 interrupts, or 128 seconds, for a flow rate of 9.99
grams
per second. This is a 1” auger feeder, from which we would typically expect about 8 grams per second. More recent auger
feeders use faster motors delivering about 16 grams per second.
In the component 4 column, 10240 and 31232 indicate a flow rate of 8 grams per second EXACTLY. Since it is exact, and since
these two numbers are, in fact, the "default" settings from when the blender was first installed, we know that "component 4" has
never been run on this blender, or at least not since the last "CLEAR ALL" was performed.
DATA line 3 dispense weight of 0.0 for component 4, and the TOP-OF-PAGE heading showing component 4 set to 00.0 percent
also confirm that component 4 is not being run.
The following information will help you determine what devices are in place on a blender.
