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[...]

Retries occur until both conditions are met. 1LA 00020 Lag TIME before dispense ACTUALLY starts. (mechanical response time, interrupts) These parameters state the lag time between when a device is signaled and when it actually begins to operate. Change ONLY if you change to non-standard equipment. 1PO 00000 Pulse rate of "MICRO PULSE" val[...]

MIX indicates the TIME that the mixer will run after the weigh bin dump valve opens. The number is the mix time in seconds. Adequate mixing can be accomplished in a short time. Additional mixing may cause separation and may create a static problem with the material. The default value is (00015), allowing an initial mix time of 15 seconds. A maximum[...]

voltage to open the valve. With this flag set the computer puts out a voltage to close the valve. For this reverse logic to work correctly, you must reverse the air lines to the flow control valve air cylinder. Normal power-off position for the valve is closed. Some customers prefer the valve open when all power is off. This option allows this reve[...]

ROC indicates the PERCENT of one REGRIND that will be treated as natural when ADDITIVE dispenses are calculated. If you feel it is necessary to ADD (or subtract) color or additive to your regrind, this parameter will automatically see that this is accomplished. The first digit is 0 to add, 1 to subtract. The second digit is the REGRIND component nu[...]

The last digit determines the adjustment rate. Zero in the last position means make the full adjustment immediately. Any value from 1 to 9 indicates the percentage adjustment that will be made each cycle when the level sensor condition changes. See RHL below for examples. ====================================================================== RHL (L[...]

Sensors that we supply are wired correctly for this logic. If a "Bindicator" or similar device is used, with a micro-switch dry contact closure signal, then wire to the normally CLOSED contact so that the signal OPENS when regrind covers the bindicator paddle. The circuit board "pin outs" for each sensor are positive, ground, an[...]

====================================================================== FUL (Change only for extremely fluffy or heavy material) FUL is the full batch weight in GRAMS set at the factory to 1000, 2000, 4000, 9000, or 18000 grams, depending on model. The criteria for this number is to not exceed the volume capacity of the weigh bin and to not exceed t[...]

====================================================================== TH AND TL (change only if material sticks in the weigh bin) 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 that it is not already full of material. To do this it looks at the st[...]

overfeeding by several grams is a distinct possibility. This type of error represents a very large percentage error to the controller. However, a large correction would not be appropriate but, instead, would cause a "hunting" of dispense time that would result in further large errors. This parameter prevents this. ========================[...]

If you know ONE bar code input is required 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. When set to any value, the blender will not operate until the required number of scanned inputs [...]

when set to 30 on a 200 series blender, this would indicate a 600 gram total error must accumulate before adjustment, 30 percent of the full 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) c[...]

CALIBRATION routine, or simply allowed to adjust automatically as necessary after each cycle. _WT and _TI are WEIGHT and TIME numbers that, taken together, indicate a dispense rate for the specified material (WT/TI). This rate is used to calculate an exact time period to dispense the required quantity of material. Both of these numbers are adjusted[...]

corrections are made by the software. Gram weight errors that are equal to, or less than, this number will be accepted and no error 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 e[...]

Retries will occur until the difference between the required amount and the metered amount is equal to or less than the _RP percent difference AND the _RD weight difference. These numbers dictate just how close to perfect the dispense has to be before going on. If the dispense overshoots the target, then the process continues. These parameters only[...]

cause some movement and DOES result in a minimum dispense. Add 5 to this time period and enter as the lag time. Lag times that are too short can cause problems. That is why the MINIMUM lag time determined above should be increased by 5 as a safety factor. These numbers are preset at the factory for the equipment we have supplied. When a dispense of[...]

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[...]

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. BAILOUT: (line 4) If bailouts occur, vibration is usually the cause and these bailouts may be causing [...]

TYPICAL PROBLEMS: These problems are based on phone calls that we have received from Autoweigh Blender users. The display does not read close to zero when power is turned on, bin empty (plus or minus 10 grams). * The load cells are not plugged in. * The weigh bin is not resting properly and freely in its platform or the platform is not resting prop[...]

Occasionally, the system gets STUCK doing retries of a component but the retry time is so short that nothing gets dispensed. * The LAG TIME parameter is set for too short a time. See KEYPAD, TIME, and PARAMETER, _LA. * A valve is sticking closed. Check for free operation when air pressure is removed. The system USED TO WORK but now it does unexplai[...]

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 [...]

LOAD CELL - WEIGH BIN TEST To verify correct operation This test is to help you determine if the load cells are working correctly, and if the weigh bin and weigh bin hanger are moving freely and registering weight correctly. Have a pad and pencil ready to write down the weight readings that appear on the display, both before and after each dispense[...]

"CLEAR" ROUTINE A "CLEAR" routine is available that will clear all data, flags, and all other current information from memory.

However, lower pressures will work. If you plant air fluctuates, set the regulator to [...]

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. Modesl 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[...]

RECALIBRATION OF LOAD CELLS This unit was properly calibrated at the factory to match the load cells that were supplied with it. If you are going to recalibrate, note the following. Recalibration can not be done until the Recalibration flag is turned ON. The proper sequence of keystrokes is given below. BE SURE the load cell plug is plugged into th[...]

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[...]

The blade assembly should slip on and off the motor shaft easily. The need to use excessive force to remove the mixer assembly may bend the blades and they may eventually break off.
