Troubleshooting with the Print Diagnostics
TOTAL BATCH WEIGHT :
Check the TOTAL batch weight 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 printouts, parameters and communications do not include the decimal
point, you will want to know if you are reading full grams or tenths of grams.
TARE WEIGHT :
In DATA Line 2, tare 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 another fault. 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.
RETRY/BAILOUT - A 4th data line (not shown in the example) will print if any single dispense
requires retries (RETRY) or is expected to go past the target weight due to a higher than expected
flow rate (BAILOUT).
RETRIES : Shown in the 4th data line under the Component Number/Type column, Retry is a count of the
number of retries to achieve the targeted dispense percentage. When FIRST timed dispense does not
equal FINAL dispense, one or more retries will 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.
BAILOUT -
Shown in the 4th data line under the Component Setting column, the BAILOUT value is the
time the dispense was cut short due to a higher than expected material flow rate.
Bailouts are designed
to prevent or minimize overflows of material when initial parameter settings, at start up, are
entirely inappropriate for the metering device. A larger then normal error correction will occur after
a bailout. Bailout 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. Bailout is set by the
BER parameter (value is model specific).
FLOW RATE NUMBERS : (DATA line 2)
Check the RATE numbers, (DATA line 2), to determine each dispense device.
In the example above:
RATE: GR/TIME 2600 4000 1999 2000 1600 32000 1600 32000 2.4
In the components 1 column, 2600 and 4000 translates to 2600 grams in 4 seconds (4000 ms). This is
650.0 grams per second, typical for a regrind flowing through 3" round or 2"x3" dispense valves.
In the component 2 column, 1999 and 2000 indicate 1999 grams in 2 seconds, or 999.5 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, 1600 and 32000 indicate 1600 grams per 32 seconds (32000 ms) for a flow
rate of 50 grams per second.
