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 adequate" control transformer.
CHECK OUT PROCEDURE As you go through this procedure, if WHAT SHOULD HAPPEN, doesn't happen, see next section, DIAGNOSTICS, for what to check. NOTE: 100/200 series models (3K load cells), display all weights in 1/10 grams ( x.x). 400/900/1800 series models (10K load cells) display weights in FULL grams, NO decimal point. On this page we show all weights with NO decimal point. Start with NO MATERIAL in any hoppers. Be sure an AIR SUPPLY is connected.
LED # 2 will light. Press "2" repeatedly to observe operation. REPEAT THIS SEQUENCE for each dispense valve on your WEIGH SCALE BLENDER. Up to 12 outputs are possible numbered 1 through 9, A, B, and C. Only those connected to devices will operate. AT THIS POINT: NOTE which component NUMBER is assigned to each hopper. You will want to know each hopper's correct component number.
DIAGNOSTICS - for the CHECK OUT PROCEDURE If display fails to come on at all: check for power at outlet. Check the 1/2 amp panel front fuse. If first display says ( FOUR ), then this is NOT the correct manual for this software. Obtain and use a FOUR software manual. Possible model numbers are: GBM, 140, 14R, 220, 240, 24R, 420, 440, 44R, 940, 184. If model number is not correct for you unit: see the next page, SELECTING CORRECT MODEL.
SELECTING CORRECT MODEL Controllers are programmed to control all sizes of Autoweigh Blenders. The MODEL number that your unit is set for will be displayed during the start up sequence every time power is turned on.
+--------------------------------------------------------------------+ ¦ PART II - OPERATION ¦ +--------------------------------------------------------------------+ LOAD CELL CALIBRATION NOTE: Displays shown here are in full grams. 100 and 200 series models are in 1/10 grams, with a decimal. If your load cells already display a weight close to zero, plus or minus 10 grams, you may skip this section and go directly to: TURNING ON OUTPUTS (next page).
TURNING ON OUTPUTS - MATERIAL TYPES This controller can control up to TWELVE (12) components; 1 through 9 and A, B, and C. You must "TURN ON" the COMPONENT outputs that you are going to use. Components that are TURNED OFF are not part of ANY routines. A component becomes TURNED ON when it is set to a MATERIAL TYPE. Material TYPES are REGRIND, NATURAL, and ADDITIVE. The AUTOWEIGH BLENDER handles each TYPE DIFFERENTLY. different meanings for each TYPE.
ADDITIVE (PERCENT OF ALL NATURALS) Components designated ADDITIVE will be added as a percentage of all the NATURALS added together. For example: If component 5 is an ADDITIVE at 5 percent, Then the above example now looks like this: component 1, REGRIND, SET=20.0, 20 percent, component 2, NATURAL, SET= 10, 15.2 percent, component 3, NATURAL, SET= 40, 61.0 percent, component 4, ADDITIVE, SET=05.0, 3.8 percent. The REGRIND is still 20 percent of the MIX.
SET MATERIAL TYPES The Keystroke sequence to set TYPES is: Press: Press: * 22222 Display will say: Display will say: (PASSWORD) (P x) Press: Press: * 14 Display will say: (INSTR --) Display will say: (1TY= OFF) The "1" is the component (device) number. This is component 1. It will control Hopper 1. Press: CE repeatedly to select one of the four Display will say: (1TY= REG). (1TY= NAT). (1TY= ADD). (1TY= OFF). options.
RATE CALIBRATION YOU DON'T HAVE TO DO THIS. Software is set to expect STANDARD hardware. If a device meters at a much lower feed rate then expected, the software will take 10 to 20 cycles to fully adjust. During this time cycles will take longer. An example of this is a system using a 1/2" auger instead of 1".
ENTERING SETTINGS Press: SET Display will say (1 R or (1 N or (1 A xx.x) xxx) xx.x) (Regrind) (Natural) (Additive) 1 is Component number. R,N,A is Type. xx.x is Setting. Enter a 3 digit setting: Regrind settings = PERCENTAGE of the ENTIRE MIX Natural settings = RATIO to OTHER NATURAL SETTINGS Additive settings = PERCENTAGE of ALL the NATURALS Press: SET for the NEXT setting. Repeat this sequence for all components. Press: EXIT when finished.

INSTRUCTIONS FOR NORMAL OPERATION OPERATION: ....very simple. 1. Fill HOPPERS. 2. Turn POWER ON. Verify correct settings. 3. On Controller, set STOP and PAUSE switches UP. Turn MIXER motor switch DOWN to run for a timed period. Unit will now operate automatically to maintain a level of material high enough to cover the sensor. Use the STOP or PAUSE switches to stop the blender. Turn POWER off only on final shutdown.
NORMAL OPERATING SEQUENCE - EACH CYCLE As the sensor is uncovered, the cycle begins. The target weight of a complete batch is 18000, 9000, 4000, 2000, 1000, or 400 grams. REGRINDS are dispensed first, in their order of size, largest dispense first. After all the Regrind dispenses, the space remaining in the weigh bin is determined. NATURALS are dispensed second, in their order of size, each at the correct ratio to the others.

11. MIXER MOTOR OUTLET This outlet is energized by the software for a time period following the dump of the weigh bin. You may adjust this time in the parameter table (MIX 00010). This time should be just long enough to provide adequate mixing. Mixing for a longer period may contribute to a static problem. Also, excessive mixing sometimes causes separation of pellets of different size and weight. (MIX 00099) will cause the motor to run for 360 seconds (6 minutes). 12.

COMPUTER input / output If you choose to gather material usage data automatically and continuously by computer, then this connector allows for connection to any IBM PC type computer operating under MS-DOS or WINDOWS. The COMPUTER port is a DB9 (9 pin) male port. You will need a specially wired cable from us to connect to the serial port on your standard PC computer. Your computer operating system must be MS-DOS or WINDOWS.
KEYPAD - SUMMARY DESCRIPTION Detailed explanations are given on the pages that follow. AUTOMATIC OPERATION MODE: VIEW: RCP: BTCH: FAST: TAG: EXIT: SET: CE: View Data: date, time, cycles, and each component weight. Press VIEW,* to print data. Enter and retrieve stored RECIPES. View BATCH data: Target Weight, Current Portion, Accumulated Total, and Batch Count. CE = clear displayed field. Run rapid FAST cycles after a normal weighed cycle. Tag Work Order and Operator numbers to all reports.
KEYPAD - DESCRIPTION OF FUNCTIONS Three (3) operation Modes are available; AUTOMATIC, MANUAL, PROGRAM. KEYPAD - AUTOMATIC OPERATION MODE This is the NORMAL operating mode. When power is turned on, the unit is in this mode. Automatic dispensing occurs ONLY in this mode. The AUTOMATIC mode is indicated by the ABSENCE of the letter "P" or "M" at the left end of the display.
recipe. Display = (GET --). If no RECIPE is currently in use, display says (GET --). Enter 2 digits to retrieve one of 50 recipes. Display will flash through this recipe data: (RCP 01), (1R= xx ), (2N= xx.x), etc., (* = LOAD) Press "*" to LOAD this recipe into memory. Routine will exit automatically. Press RCP or EXIT to return to the display (GET --). Press RCP or EXIT again to exit. To SAVE a RECIPE you must be in the PROGRAM mode.
Press again to view the total BATCH COUNT. Display will say (BC #####). BATCH COUNT is the total number of batches that have run. This number will continue to grow until it is manually cleared to zero, or it exceeds its maximum possible value. Press again to return to normal operation. When any of the above totals are being displayed, you may press the CE key to RESET that number to zero. While all four totals can be cleared to zero manually, only the BATCH WEIGHT number can be entered manually.
dispenses take much less time. in this manner. Throughput is easily doubled This key is NOT FUNCTIONAL unless the 4th digit of the "FLG" parameter is set to 1 (xxx1x). To do this, see the SOFTWARE MAINTENANCE section, PARAMETER TABLE, "FLG". The shorter mixing time may be a problem. So the number of FAST REPEAT cycles is kept as low as possible. Up to 4 repeats may occur. Press the FAST key to toggle the FAST flag ON of OFF. When set to (FAST OFF) the FAST mode will not operate.
Press once to display the current Work Order number (WO-----). Press again to display the current Operator number (OPRTR---). Press again for the Recipe (RECP ---). You may enter or change the Work Order or Operator number, when each is displayed, but not the recipe number. These numbers are for your TRACKING of information ONLY. They have NO EFFECT on the operation of the Weigh Scale Blender.
any other 5 digit number, if you wish, as explained later (*45). When in the MANUAL mode, the letter "M" shows at the left end of display. The following manual functions are available in the MANUAL mode. OPERATE: (OPER) Press once followed by one of 16 keys: 1 through 9, A, B, C, DUMP, ALRM, MIX, or HOLD. The selected output operates until the key is pressed again or another output is selected. Only 1 output will be active at a time. EXIT will exit the sequence and close all outputs.
and EMPTY when this key is pressed. Since the bin, even when empty, weighs about 1300 grams, it is necessary on initial setup of equipment to instruct the controller of the exact tare weight of the empty bin. Slight drift in the tare or zero weight during day to day operation is normal. All weight calculations automatically compensate for this drift.
same load cells, the accuracy of these ratios is not affected by zero or full scale errors. STAR FUNCTIONS available in the MANUAL mode: *00 Press (*,0,0) to CLEAR ALL DATA fields. These are the material usage totals that are viewed with the VIEW key. If you are tracking material usage, you should record these numbers periodically but clearing these totals is entirely optional and not necessary.

Press * to toggle this flag to ( RATE ), (EXT CTRL), or (YLD CTRL). If you are using our EXTRUSION or YIELD control software to control your extruder, refer to our EXTRUSION CONTROL instruction booklet for complete information.
number that will make all natural settings add up to 1000. In this way each NATURAL setting will represent a percent of the total natural blend. If the sum of natural settings exceeds 1000, component 2 will be set to 000, and the other naturals will be ratioed to each other. The TY and CS parameters are the ones that are altered. TY sets TYPE to Regrind, Natural or Additive. CS assigns the thumbwheel swatches.
EUROPE will cause all dates to display DAY/MONTH/YEAR. The remaining five entries are two digits each; MONTH __, DAY __, YEAR __, HOUR __, and MIN __. Use the * key to step through all displays without change. Enter new settings where required. The correct date and time have been entered at the factory and should never have to be reset. Of course you may be in a different time zone. *12 Press (*,1,2) to move the PARAMETER table from ROM to RAM.
Should it fail, we suggest that it be replaced at our factory. *23 Press (*,2,3) to move the PARAMETER table from RAM to EEPROM. This information is then available for retrieval using the "CLEAR" routine or by using the *32 function described next. *32 Press (*,3,2) to move EEPROM information to RAM. This is useful for retrieving special information tables that you may have stored earlier in the EEPROM.
set, (ROM OK ) will be displayed. To turn the flag off, you must select this option, (*25), and, with (ROM BAD) displayed, press the "CE" key. This will clear the flag and it will remain off until another error is detected. The seriousness of the problem will be somewhat indicated by the date and time of the last bad check and how frequently you find it necessary to turn this flag off. Even with an error, your controller may still work perfectly.
on line, four lines of information about the dispense cycle that just occurred will be sent to the printer. This information includes dispense weight and percentage of each component, the internal rate numbers used by the computer to determine dispense time, and the actual dispense time of each component. This is excellent information to track the accuracy of each dispense cycle and the accuracy of the entire system over an extended period of time. See: PRINTER OUTPUT for a more detailed explanation.
PASSWORD number for entering the PROGRAM mode. The system is supplied with the number "22222" as the password number. If you wish to restrict use of this mode to only yourself, you may make up your own number and enter it here. If you forget your password number, call us. *82 We can help. Press (*,8,2) to produce a precision ratioing of a selected Additive. Press CE to toggle between (P/R OFF), (P/R 1), (P/R 2), etc. Only those components already designated as an ADDITIVE will be displayed.
Use the "CE" key to toggle a component ON or OFF. When ON, Display will say (C=ON 85). You may change the 85 by entering a different number. Too low will just add time. Too high will cause occasional overshooting. Press EXIT when done to save new settings. *86 Press (*,8,6) to select a new "Back Door" password for your software. Display will say (BDP 00000). Enter 00001 up to 00009 to select one of nine new backdoor passwords. Contact us for the actual number.
recalibration does not take place. The unit functions like a volumetric feeder without checking or correcting for errors. Since load cell readings are ignored, this flag allows operation even if the load cells become damaged. Dispense times will be based entirely on the WT and TI parameters. *88 Press (*,8,8) to force a printout of the display on the controller front. DATE, TIME, Machine number, and display will print: Date: 11/09/93 Time: 17:22:01 Machine number: 002 Display Readout: P 500.
PARAMETERS All AUTOWEIGH BLENDER controllers operate according to certain internal PARAMETERS. Because customer requirements vary widely, we have made over 160 parameters accessible for change through the keypad. There is one GENERAL group and twelve COMPONENT groups. BRIEF explanations are given first. the section that follows. FULL information is given in NOTE: Values shown here are initial ROM values of a model 940. values for other models are listed at the end of this section.
This parameter times how long the weigh bin dump valve opens to empty. No change is required. KDF 00002 WDF 00002 Maximum variation in GRAMS between two consecutive weight readings for reading to be accepted. (x or x.x) KDF controls sensitivity of weight readings during calibration of load cells. No change is required. WDF controls the sensitivity of weight readings during normal operation. If excessive vibration interferes with weight readings you may have to increase this number.
This parameter is the time that the sensor must be uncovered before a cycle will begin. PRC 00010 Maximum allowable PERCENT rate change per cycle. This prevents excessive swings in flow rates by the software. not change. STL 00122 Do Dispense settle TIME before a weight reading is taken. The time (interrupts) allowed for material to SETTLE in the weigh bin before a weight is taken.
operate. 1CS 00000 See: "TURNING ON OUTPUTS" to complete this. Thumbwheel assignment or current setting entry. This parameter reflects the current setting or thumbwheel assignment for this component. No entry is required here. 1AL 00000 Last digit = number of retries before ALARM. 00001 to 00009 = sound alarm, hold process. 00011 to 00019 = sound alarm, continue process. These parameters set ALARM functions.
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" valves.
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 setting of 29999 is possible, for a mix time of over 8 hours. Setting the mix time to 99 (MIX 00099) will cause the mixer to run 360 seconds (6 minutes).
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 reversed "power off" position. With power on, no difference is apparent.
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 number you will be making this adjustment for.
The last digit position means to 9 indicates when the level determines the adjustment rate. Zero in the last make the full adjustment immediately. Any value from 1 the percentage adjustment that will be made each cycle sensor condition changes. See RHL below for examples.
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, and signal. If you are wiring using a dry contact closure, only the positive and signal lines are used.
====================================================================== 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 the load cell capacity. On a 9000 gram system, load cells are rated for 10,000 grams each. Total load capacity is 20,000 grams.
====================================================================== 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 starting TARE weight. If Tare weight is below the value of TL, (50 grams), the software assumes that the bin is either missing or hung up on something.
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 are received. ====================================================================== XCV + XRC For Extrusion Control Systems only.
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) control. This is a factor during startup only. Larger numbers assure a very accurate rate has been learned.
generates. ====================================================================== MPO for Micro Blender air driven reciprocating mixer. MPO sets the timing, in tenths of seconds the clockwise and counterclockwise timing of the mix blade. MPO 00010 is 1 second for each direction. ====================================================================== LIQ For LIQUID COLOR applications using dual pumps / drums.
====================================================================== COMPONENT PARAMETERS _TY (12 Groups of 13 parameters each) (Designates material type for this component) _TY is the number that what material TYPE it is. Material TYPES are REGRIND, This parameter is stored as letter word: OFF = Component REG = REGRIND, NAT = NATURAL, ADD = ADDITIVE. designates if this Component is used and NATURAL, ADDITIVE, or NOT USED.
RATIOED to each other and will constitute the ENTIRE mix except for space needed for Regrind and Additives. ADDITIVE; all the materials that are added to the NATURALS only; color, stabilizer, slip agent, etc. ====================================================================== _CS (Set AUTOMATICALLY when you enter settings) _CS parameter stores the current setting that has been entered through the KEYPAD, "SET" function, for this component.
such as regrind, but you wish the process to continue even without the component. 00021 to 00029 = same as 1 to 9, Stop Process, Sound Alarm, but NO more retries. Just sound alarm and wait. Press the RESET button to clear alarm and start the retries again. Appropriate ONLY if you absolutely want operator intervention to occur when material runs low. In other words you do not want any automatic loading or other correction to allow the process to continue.
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 by the computer logic after each cycle as a means of continuously calibrating the dispense times.
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 error range. This parameter is adjusted automatically by the software according to the actual conditions of the metering.
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 control the degree of weight SHORTAGE that is acceptable. The _RP parameter is important when SMALL DISPENSE requests for color or additive are made.
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 only a few grams is required, the _LA number is very important.
PARAMETER DEFAULT SETTINGS - TWELVE SOFTWARE Here is a complete list of the "default" entries for all parameters as they are provided in the original program, and as they will appear after a CLEAR ALL or a model change. The Model 200 list is the ORIGINAL BASE list. Models 100, GBM, and 900 show only the changes from the 200 list. Models 1800 and 400 show only further changes from the 900 list. Component 1 is the base list for all components. Other component lists show only the changes from list 1.

print for additional components as necessary, printing only those components turned on. Thumbwheel setting and material type is shown for each. If a thumbwheel setting is changed, a new header line will print. In this example, component 1 is a REGRIND; component 2, a NATURAL; 3 and 4 are set up as ADDITIVES.

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 correct first try for the dispense. The last number (22) is the CYCLE count, a convenient way to keep pages of data in order, like page numbers.
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.
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 only if the GRAM number goes below 16,000 or above 32,000 (approximately).
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 time to every dispense.
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 other problems. Raise the value of the BAL parameter to 200 or 300 grams to reduce or eliminate unnecessary bailouts.
MATERIAL USAGE INFORMATION Pressing the VIEW key followed by the * key will cause all material usage totals to be printed. The (*54) flag need not be on. These totals are since the last time printed, and since the last time cleared. This same information may be periodically, and automatically, printed by setting the PRT parameter to a time interval number.
+---------------------------------------------------------------------+ ¦ PART IV - TROUBLESHOOTING ¦ +---------------------------------------------------------------------+ WHAT TO DO If you are reading this section, you are having problems. To locate and correct the problem we suggest that you take the following steps: 1. Start by reading the WIRING CONSIDERATIONS section. Even if the system worked well for a time, dry weather or increased plant electrical noise can cause new problems. 2.
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 properly on the bolts that protrude from the load cell enclosures. * The controller was never calibrated for these load cells or you just did a CLEAR ALL.
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 unexplainable things. * Static or a voltage surge has altered RAM memory. Do a CLEAR or CLEAR ALL. See "CLEAR" RESTART or "CLEAR ALL" RESTART.
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.
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. ADDITIVES third: The ADDITIVE dispenses occur last in the sequence. Each dispense must meet requirements set by internal parameters or RETRIES will occur and the sequence will not continue.
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 starting point. If this does not happen, something is interfering with free movement of the cell or the bin.
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 handle a range of counts from 0 to approximately 249,850.
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. If you prefer, you can use a printer to record all test data. Have the printer flag (*54) set to ON. Be in the PROGRAM mode. (*22222). 1.
"CLEAR" ROUTINE A "CLEAR" routine is available that will clear all data, flags, and all other current information from memory. Since MEMORY is battery backed up, turning power off does not clear all fields. A great deal of information is intentionally held for later use. A "CLEAR" routine will clear all RAM data and start with the information stored in the EEPROM. This is the same data that existed when new or data that you may have intentionally saved earlier.
+--------------------------------------------------------------------+ ¦ PART V - HARDWARE MAINTENANCE ¦ +--------------------------------------------------------------------+ HARDWARE ADJUSTMENTS AIR PRESSURE Set AIR PRESSURE to about 80 PSI for best accuracy. However, lower pressures will work. If you plant air fluctuates, set the regulator to the low end so that the dispense valves always see a consistent pressure. Lubricated air is NOT recommended. GBM Micro Blenders should be set to 40 PSI (2.7 bar).
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 material in the mix chamber immediately after a dispense.
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 less processor problems.
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 the side of the controller. BE SURE the weigh bin is hanging from the load cells freely.
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 once a year, and all necessary repairs be made to insure continued accuracy.
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. Correct this if it is a problem. *77 and *54 PRINTOUTS After you have fixed any problems, use the *77 and *54 functions to obtain printouts and fax them to us for evaluation.
