WIRING CONSIDERATIONS The wiring of your blender is very important to its proper operation. Electronics are very susceptible to voltage spikes and static charges, both of which are very common in plastics factories. To MINIMIZE these things, consider the following. 1. The power supply should be solid; a strong supply, not limited by a "just ad[...]

RATE CALIBRATION RATE CALIBRATION is probably not necessary. The software initially expects STANDARD hardware. However, if you are using an auger feeder on a model with four dispense valves, or a 1/2 inch auger instead of a 1" auger, the software will take 10 or 20 cycles to adjust to correct operation. This slows down the process for a short [...]

digits (FCV 000xx). If your unit is equipped with a Flow Control Valve, under the mix chamber, it is programmed to open whenever the sensor is covered. It will close again immediately when the sensor is uncovered. This assures that material has time to mix before dropping into a bin below. When a batch is dropped into the mix chamber the sensor is [...]

target weight during the dispense, a BAILOUT occurs. This ends this dispense immediately just like reaching the end of the dispense time. This in no way effects accuracy. The dispense is checked and retries occur if required. A bailout does not occur unless target weight is exceeded by the weight given in the BAILOUT ERROR parameter. This is primar[...]

ROC parameter (ROC 10000), will cause a portion of the Regrind to be SUBTRACTED from the Natural portion, instead of added. EXAMPLE: ROC set to (ROC 10020). The 20 means take 20 % of the REGRIND dispense and ADJUST the NATURAL dispense by this amount. The 1 means adjust by SUBTRACTION. Whatever amount of REGRIND is added, 20 percent of this amount [...]

the system takes this to indicate that the regrind hopper is now empty, and the controls revert back to normal. ====================================================================== RHL (LEVEL SENSORS are required for this parameter to work) (Use only if you have regrind level sensors fitted) RHL instructs the controller to change the regrind sett[...]

Example: RHL is set to 90 and 10 percent (RHL 09010). ROV is set to zero, (ROV 00000). The "Regrind" thumbwheel switch is set to 25 percent (025). The Software logic is as follows: If material level is high, above the high sensor, the HIGH sensor is COVERED, (returns NO signal); Regrind runs at the HIGH setting; 90 percent. If material le[...]

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[...]

_SE (This might be useful) _SE is the upper SETTING limits for the thumbwheel switches. This allows a reasonable cap to be set for each component so that an operator cannot accidentally set the controls to an excessively high setting. For color and additive, these limits will ensure that expensive material is not wasted. Thumbwheel settings that ar[...]

interruption for the full specified DELAY time. To prevent false starts from the mix blade, a 1 second minimum (00244) is recommended. Sometimes throughput is slow enough that each new batch buries the mix blade for a while. When this happens the material on top does not mix well. To reduce this, you can delay the start of a new batch by adding to [...]

This rate is used to calculate an exact time period to dump the required quantity of material. Both of these numbers are adjusted by the computer logic after each cycle as a means of continuously calibrating the dispense times. This rate correction takes place continuously and the battery- backed RAM maintains the correct rate even when power is tu[...]

corrections will take place. Since no equipment is perfect, we must accept that a certain range of error is normal. To make corrections within this range only adds an additional error due to hunting, and broadens the error range. This parameter controls and prevents this. This parameter is adjusted automatically by the software according to the act[...]

to occur when very large dispense percentages are being requested. Depending on the accuracy of the metering device, a certain amount of hunting is to be expected from one dispense to the next. Allowing the software to stop trying when it gets sufficiently close to the target results in more perfect average dispenses. The mix chamber and the barrel[...]

is required, the _LA number is very important. A lag time number that is too small will result in no dispense at all because of inadequate time for the device to operate. A lag time number that is too big may result in over dispenses when very small amounts are called for. Since too small a number may stall the process, always add 2 to the minimum [...]

If you know ONE bar code input is required to before a new cycle is initiated, set this parameter to 00001. The blender is then prevented from operating until one single valid input is received. If two inputs are expected, set this parameter to 00002, etc. ====================================================================== XCV + XRC For Extrusio[...]

batch weight of 2000 grams. The FIRST TWO digits indicate how many cycles must run without a rate adjustment before the operator is permitted to switch from voltage (manual) control to Throughput (automatic) control. This is a factor during startup only. Larger numbers assure a very accurate rate has been learned. This is preferred if you like the [...]

PTD Yield Control - extrusion control - Pulse Train Delta This allows some error in the pulse train rate. For example, if the pulses are being generated at a rate of 6030 per minute, which is 100.5 per second, and we count pulses every second, then we will count 100 for one second, 101 for the next, then 100, then 101 and so on.

If the first dispense weight, (data line 3), matches the final dispense, (data line 1), then no "retries" occurred. In other words, the first try was accepted by the software. If they do not match, then the first try was short and one or more retries occurred. The second number is the dispense time that the software calculated to be a cor[...]

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[...]

ERROR CORRECTIONS: RATE NUMBERS. (DATA line 2) The RATE numbers are used by the software, each cycle, to calculate material dispense times. They are adjusted every cycle until flow rates stabilize. When a significant error is detected, the software adjusts the RATE numbers. The GRAM number is adjusted first. The TIME number (interrupts) is changed [...]

small amounts, but are using a high rate dispense valve to do the job. An auger, a vertical valve, a horizontal valve with a flow restrictor, or a smaller valve would help to improve accuracy and control. If the timing number is below 5, you are operating in a range were it is difficult for the blender to perform well. The LAG time parameter adds t[...]

3. Third, look at the dispense TIME (DATA line 3). Very short times (10, 20, 30 interrupts) indicate dispense devices not well matched to the task. Accuracy on a percentage basis, cycle to cycle, will suffer. This may very well be acceptable as long as overall usage percentages are still accurate.

INCREASING THROUGHPUT A correctly sized blender should have throughput that always exceeds your process requirements. If, for some reason, your blender is not keeping up, here are a few ways to increase throughput. 1. If your blender is equipped with a flow control slide gate, under the blender, this will reduce throughput up to 25 percent. To coun[...]

TYPICAL PROBLEMS These problems are based on phone calls that we have received from GB/WSB Autoweigh Blender.

VERIFYING LOAD CELL FUNCTION Most Problems are related to LOAD CELL function. There are several ways to VERIFY that the load cells are functioning properly. The slightest touch on the weigh bin should result in a change in the readout. If this is not the case, something is wrong. When the light touch is removed, the display should return to its sta[...]

LOAD CELL RAW SIGNAL READOUT Press "CE" key to check this RAW number for several seconds. Load cells put out a very small voltage that varies slightly as the load cell is deflected. This voltage is converted, on the circuit board, to a pulse train and these pulses are counted for 1 full second to determine a weight load. The software can [...]

CLEAN OUT ISSUES We always try to design with clean out in mind. For this reason all models have removable weigh bins, mix blades, and mix chambers. Selected models have additional clean out issues. GBM Micro Blenders and all blenders with removable hoppers use our verticalor pivot style valves. Most pivot valves are fitted with a sleeve over the a[...]

MIX PROBLEMS Customers with mix problems have several options available. 1. Decrease the batch size by lowering the FUL parameter value. This does two things. First, it causes the components to be dispensed in smaller, more frequent batches which places more and smaller layers of material into the mix chamber. Second, it lowers the level of materia[...]

9. Models GB/WSB-GBM, 100 series, and some 200 series units use an air drive for the mix blade, instead of an electric motor. Air drives have these advantages: a) Improved mixing due to back and forth motion of the blades. b) No EMF (Electro Magnetic Force) feedback to the processor from electrical demands of the motor resulting, the results in les[...]

BLENDER PREVENTIVE MAINTENANCE There are no components of your blender that require periodic maintenance. However, over the years, blenders may be subjected to abuse or difficult conditions, and accuracy can suffer. To maintain control over the cost of expensive color and additives, you must maintain accuracy. We recommend that blenders be examined[...]
