2-3 Typical Features and Components Mechanical Features • Exclusive diamond design slide gate metering assemblies meter a large range for free flowing pellet materials • Adjustable Slide gate stroke limiting restrictors provided for accurate metering of minor ingredients (not on 150#) • Removable Stainless steel weigh hopper and mixing components • Powder Coated Mild steel material supply hoppers with machined polycarbonate clean-out doors and optional material drains (stainless steel on 150#) • Precision
• Three (3) types of recipe entry procedures available: o Quickset mode (up to 6-component) recipe entry. Color and additives are metered as a percentage of the virgin material. o Percentage mode recipe entry. Ingredients are metered as a percentage of the overall batch. o Parts mode recipe entry (i.e.
Slide Gates Air operated slide gates are provided to meter the majority of pellet ingredients on Slide Gate blenders. Note: The metering range assumes 1/8” diameter free-flowing plastic pellets weighing approximately 35 lbs./cu. ft. This is meant to be an approximate sizing recommendation and can vary with different bulk density resins, pellet configuration, etc. A stroke limiter (included) can be installed on the metering gates to limit their travel.
Figure 6: Typical Slide Gate Assembly Each of the diamond gate air cylinders is actuated by a solenoid valve, which are controlled by the blender controller. When the solenoid valve is energized, it opens the metering valve cylinder. When the solenoid valve is de-energized, it closes the metering valve cylinder. If the power is interrupted to the blender, the metering valves will return to the closed position, to prevent material from over-filling the weigh hopper/mix chamber.
Figure 7: Typical Weigh Hopper Assembly The weigh hopper dump door holds the material until it is dumped into the mixing section. The cylinder is actuated by a solenoid in the valve stack on the side of the blender. In looking at the pneumatic circuit, you can see that the air regulator controls the flow of air to the valve stack.
Mix Chamber All of the batch blenders are equipped with an integral mix chamber. The mix chamber holds multiple batches of material so any variations in a batch are averaged over time. Figure 8: Typical Mixer Assembly The Opti-mixer™ is designed to provide bi-directional mixing action and can be easily taken apart for cleaning. This design is standard on all Slide Gate blenders. Operator Control Panel Display The operator control panel includes a 32 foot (10.

2-4 Optional Components The following is a list of options, which your blender may have been equipped with: Pneumatic Slide Gate below Mixer The Slide Gate/Auger blending system can be equipped with an optional pneumatic slide gate below the mixing chamber. The gate is used in applications when the blender is mounted above a large hopper, or for gaylord filling, etc. This gate holds the material in the mixing section, to ensure that it is properly mixed.
Regrind Auger Metering (R.A.M.) Hopper Used for feeding difficult regrind materials. Figure 15: Typical R.A.M. Hopper Blender Configuration Additive Feeder Hopper Used for feeding pelletized additive, typically used on blenders with more than six components. Figure 16: Typical Additive Feeder Configuration Take-off Compartments Allows material to be metered into a vacuum conveying system.
2-5 Safety Features This section includes information on safety devices and procedures that are inherent to the Gravimetric Batch Blender. This manual is not intended to supersede or alter safety standards established by the user of this equipment. Instead, the material contained in this section is recommended to supplement these procedures in order to provide a safer working environment.
unplug the unit from its power source and tag it out. The plug can then be tagged with any number of approved electrical lockout tags available at most electrical supply stores. Figure 17: Electrical Disconnect Plug Twist Cap Plug Connected to Each Feeder Auger Motor The cap plug must be turned counter-clockwise to loosen and the female end of the cord removed from the motor plug. This disables the motor from turning while the auger unit is being serviced or cleaned.
Electric Safety Interlock Switch A unique electric safety switch is used to shut off power to the blender any time the mixer door is opened. Do not alter or tamper with this switch in any way. Figure 19: Electrical Safety Interlock Switch (Located on mixer door) WARNING! Bulletin Number Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air) sources prior to servicing or cleaning the Slide Gate/Auger Blender. Failure to do so may result in serious injury.
Chapter 3: Installation 3-1 Uncrating the Equipment Slide Gate/Auger Blenders are shipped mounted on a skid, enclosed in a plastic wrapper, and contained in a crate. 1. Remove crate from around blender. 2. Secure strap of proper lifting capacity to both lifting lugs (See Figure 20 below.). Caution! Use approved safety straps or chains to lift the blender at the marked lifting points. 3. Lift blender until strap is taut. 4. Remove bolts attaching bottom of blender to shipping skid. 5.
4. If equipped; adjust the four leveling bolts on the floor stand blender support rails. 5. Mount the material conveying system receivers on the top of the blender supply hoppers. 6. Align the weigh hopper on the load cell brackets. Carefully adjust the load cell brackets to ensure that the weigh hopper is centered on the brackets without rocking. If for some reason the locating tabs do not align with the weigh hopper, they can easily be loosened and adjusted.
Using proper lifting equipment, lift the blender, using the lifting lugs attached to the top plate of the blender. These lifting lugs can also be used to fasten horizontal or angled braces to the blender if more stability is needed. Note: Larger blenders need to be braced as part of the installation. Take care to insure proper orientation with adequate access to operator controls, mix chamber, and metering units.
If possible, use rigid tubing. Some flex hose will tend to sag and generate static that could cause de-mixing between the blender and the extruder. Make sure that adequate space is around the blender (36” recommended) to allow proper cleaning, servicing, etc. Floor Mount (Central Blender) In a floor mounting application, ensure adequate clearance for all blender operations and maintenance. The operator and maintenance personnel must have access to parts of the blender.
3-3 Electrical Connections The standard Slide Gate/Auger blending system is designed to operate on 120/1/60 supply voltage (220/1/50 CE models are also available). The current requirements vary with the blender’s size and throughput rating. For exact current requirements, check the blender serial number tag, located on the rear plate of the mixer section. If a step down transformer was provided, it should never be used to power anything other than the blender. Loading equipment, etc.
The manufacturer provides all pneumatic lines on the blender piped to a single ¼” NPT standard pipe thread fitting. The Slide Gate/Auger blending system requires approximately 1 cfm (1.7 m³/hr) @ 60 psi (4.14 bar) maximum air pressure for proper operation. The working pressure of the blender cylinders is not to exceed 60 psi (4.14 bar). This is adjustable by the regulator supplied on the rear panel of the blender.
Weigh Hopper Installation Remove the weigh hopper from the shipping box and install it in the blender on the load cell brackets. Connect the airline and close the mixer door, securing the latch. Figure 25: Weigh Hopper Note: THE WEIGH HOPPER ASSEMBLY MUST HANG FREELY AND BE FREE FROM FRICTION, WITH NO MECHANICAL OBSTRUCTIONS OTHER THAN THE LOAD CELL ITSELF. Final Connections Connect the blender to the appropriate power source.
This screen displays the software version of both the PLC and the PanelView. The Controller will stay on this screen for about 10 seconds or you can touch the picture of the blender to quickly skip to the Recipe Screen (Next Screen in sequence). The software versions are also available on the Panel View Configuration Screen.

Blender Calibration The load cells on the Auger blender are FACTORY CALIBRATED. Since the load cells can be subject to shock loading during shipping, moving, etc., we recommend that they be recalibrated. The heart of the Auger blending system is the load cell with the supply calibration weight. They monitor the weight off each ingredient added to the blender weigh hopper.
Figure 28: Display Calibration Menu Screen 3. Once in “Scale Calibration”, enter in the scale calibration weight value stamped on the side of the weight. 4. The controller will prompt you to remove the weight hopper and press OK. 5. After touching OK, the controller will display “PLEASE WAIT...” 6. Next, the controller will ask you to hang the calibration weight on the right loadcell bracket (loadcell A) and press OK. 7.
5. Add the calibration weight to each load cell mounting bracket and write down the value displayed in “weight”, as in step 4. 6. Subtract the values recorded in step 4 from step 5. This is the measured weight. If the measured weight is within a 0.003 pounds of the weight stamped on the calibration weight, then you are within spec. If not, follow the steps above to calibrate the blender.
3. Select a feeder (1-6) by touching the “Select Feeder” box. 4. The current settings for the hopper that you have chosen will now be shown on the screen. 5. Make the necessary adjustments to the “Stop/Continue if “Out of Material,” Alarm/No Alarm on “Out of Material,” and Out of Material Alarm Silence Delay (060 seconds) settings.” Once the settings for these features have been set on the displayed feeder, select a new feeder to configure as desired. 6.
Additional Setup Parameters The settings listed below are set at the factory and typically do not require any change. 1. From the “Recipe” Page, touch the Manufacturer’s icon and enter “5413”, then press the “Enter” key. Note: If the controller is set to Continuous Mixing, then the blender will run continuously while the blender is operating. If it is set to “Timed Mixing” then the mixer will run for the “Mixing Time” setting when a batch is dumped into the mixer. 2.
3-6 Initial Startup The operator can startup the blender by selecting the button that says, “Push to Start or Stop” (startup) on the left side of the Recipe Screen, depending on whether the blender is currently running or is stopped. Simply touch the button to either start or stop the blender. If the operator selects “Stop Blender” then the current batch in progress is first finished and then the blender will stop making new batches.
Chapter 4: Operation 4-1 Start-up General Operation The general operation of the Slide Gate/Auger blending system is as follows: Once the system is properly installed and set up, the system will be ready for operation. Please see the Installation and Setup chapter in this manual for further information. Once the Slide Gate/Auger blending system is powered on, the unit will display the recipe screen (the recipe format should be in “Quickset” recipe mode).
Note: The blender monitors the operator’s entries and determines if the recipe is valid before accepting the new recipe. If there is an error (such as the recipe does not add up to 100% and the blender is in Percentage Mode.) then a message is shown on the Recipe screen to alert the operator of the problem. The “Accept New Recipe” button is only shown if the recipe is valid and different from what is currently running on the blender. Note: Recipes can also be changed while the blender is running.
Operator Displays The Slide Gate/Auger blending system utilizes a standardized menu format. Each screen was designed to be user-friendly and provide the operator with the necessary information to run the blender. Figure 33: Typical Recipe Entry Operator Screen A typical menu is shown in the figure above.
While the blending system is in operation, there are a couple of displays available to the operator. These displays are selected simply by pressing the “NEXT” key when the unit is running. The default display shown when the blender is in run mode is the Recipe Screen. The Recipe Screen indicates by feeder number, the amount of material metered into the weigh hopper assembly by that particular feeder. This display is updated after each component dispenses its specified amount.
Upon Start Up, the blender controller will default to the “Recipe Menu” screen. The “Recipe Book” screen can be accessed in the “Recipe Page” and is useful in storing and retrieving recipes. The Recipe format option can be accessed in the Setup screen and is used to select one of three available formats: “Quickset” Mode, Percentage Mode or Parts Mode. (“Quickset” mode is the default setting preset at the factory.
“Quickset” Mode (Most common in injection molding) The “Quickset” menu structure allows recipes to be entered and adjusted by touching the buttons on the panel face (for 1 to 6 components). In this mode, hopper #1 is configured as virgin, hopper #3 is configured as regrind, and the others are configured as additives, i.e. color. The operator enters in the percentage of regrind and additives, and the virgin percentage is automatically calculated.
Figure 36: Example Calculations of a 5-component blend in “Quickset” mode Virgin (NAT): ??? Additive1 (ADD): 5.00% - of virgin component Regrind (RGD): 30.00% - of total batch Additive2 (ADD): 2.00% - of virgin component Additive3 (ADD): 1.00% - of virgin component Batch Size: 10.00 lbs. Total available: 100.00% Regrind: 30.00% Balance: 70.00% Virgin + Additive 1 + Additive 2 + Additive 3 = 70.00% Virgin + (5% of virgin) + (2% of virgin) + (1% of virgin) = 70.
“Percentage” Mode (Most common in extrusion and blow molding) Extrusion processing often requires recipes in percentage format, especially if regrind is not involved, i.e. blown or cast film. In this mode, operators enter in values for each hopper up to 100%. The total of all the hoppers must equal 100%. If they don’t, an error message appears on the Recipe screen and prevents the recipe from being accepted. All hoppers are a percentage of the total batch size.
Because the blending systems must handle a wide variety of materials, with varying bulk densities, the actual amount of weight of material the weigh hopper will hold can vary dramatically from application to application. This feature allows the operator to change the size of the batch to be made. A value will need to be entered between 0.5 to 99.9. This can also be changed while making a batch without affecting the current running batch.
To enable this feature, simply enter a desired shutdown weight value (from 1 to 999999999) into the Inventory Shutdown display line of the Recipe Format screen, under the Setup menu. This feature can be configured while the blender is making a batch. If the Inventory Shutdown is changed, then you will need to touch “Accept New Recipe” on the Recipe screen before the change can take place.
Selecting “Mixing Time” from the “Mixer and Dump Setup” menu will allow the operator to view the current time setting for the mix timer and to adjust it as needed. The mix timer is set to a default time of four (4) seconds. This time can be adjusted up or down depending on the amount of mixing needed for the materials being blended.
Weigh Hopper Dump Cycle The dump cycle allows the weigh hopper dump valve to cycle, or open and close, a number of times prior to commencing with the next batch cycle. The setting allows from 1 to 9 dump cycles between batches (open and closed cycles). The normal and default factory setting is 1, meaning the weigh hopper dump valve will open at the end of the weighed batch and close after the batch is discharged into the mixer.
Max Hopper Weight Exceeded, check batch size: This alarm indicates that the weight in the weigh hopper has exceeded the maximum allowed weight. This alarm can happen if the operator changes material density and does not perform a feeder calibration, but will usually be automatically fixed after the first batch. As long as this alarm doesn’t continue to reappear, then the operator should not be concerned. If the alarm continues to occur, then the operator should have maintenance check the blender.
PLC Battery Low: PLC battery is low and may cause the blender to lose both the program and the blender configuration. Notify Maintenance immediately. Figure 45: Typical “PLC Battery Low” Alarm Screen PLC BATTERY LOW Blender Powered On/Off: These are only logged in the Alarm Log and does not cause a pop-up message or audible alarm. Each time the blender is powered on or off, the time and day is logged to the Alarm Log.
Feeder Clean Out Any feeder in the Slide Gate/Auger blending system can be emptied and refilled with a different material. To do a feeder clean out, the operator has to press the “Clean Out” icon key from the recipe screen (the first screen that appears on power up). This screen will allow you to Open or Close the Feeder, Weigh Hopper, Mixer Knife Gate, Empty the Entire Blender, Start or Stop the Mixer Motor, Test the Alarm Output, Find out the Mixer Proximity Status and monitor the Current Hopper Weight.
Delay” timer. (See Page 51). Once the dump delay timer has timed out, the controller will activate the weigh hopper dump valve, initiating the weigh hopper dump cycle. The open weigh hopper dump door will allow the material to drop into the mixer section of the blender. If the dump delay is set, the mixer will start before the weigh hopper dump will open for the selected time. The blender will sit at rest until the high-level sensor in the mixing chamber is uncovered to start another weigh cycle.
Figure 48: Typical Recipe Book Operator Screen Erase One Stored Recipe Select a Stored Recipe Erase Entire Book Stored Recipe Details Load Stored Recipe Go to Recipe Page Save Running Recipe to the Book The save current recipe to book function allows the operator to save the contents of the current recipe to the recipe book under a desired number. Upon selecting this function, the operator will be prompted for a reference recipe number. This may be any number from 1 to 50.
number which contains the recipe he wishes to view. Once a valid recipe number is entered, the display will indicate the contents of the stored recipe in percentages. Erase Recipe or Entire Book The Erase Recipe or Entire Book function is used to eliminate old or outdated recipes from the recipe book. If the operator only wants to delete one recipe, the configuration for that recipe should be currently displayed on the screen.
8. If any other ingredients need to be changed for the next recipe, simply drain the larger hoppers with the drain tubes provided on the side of the hoppers. When the material level is below the drain tube, open the slide gate manually to dump the rest of the material. If you wish to speed the emptying process, material can be manually drained out of the slide gate assembly into a dump chute or bucket, while draining from the drain tube. 9.
Chapter 5: Maintenance 5-1 Preventative Maintenance Schedule The mechanical design of the blender is very simple and very little maintenance is required. The only moving parts are the metering gates, weigh hopper dump valve, and mixer agitator. The checklist below contains a list of items which should be inspected and/or replaced to keep your blender operating at peak efficiency. Perform each inspection at the regular intervals listed below.
5-2 Preventative Maintenance Our blenders need periodic maintenance to provide long dependable service. Check these elements regularly: • Check functionality of safety circuit daily. • Maintain proper air pressure and drain water from trap assembly on regulator – as required. • Periodically lubricate slide gate rails. 5-3 WARNING! Always remove plug and disconnect power before servicing blender. WARNING! Always read operating manual before operating or servicing blender.
Input Signals to Programmable Controller The Slide Gate/Auger blending system has two main input signals that it uses from the blending process: the mix hopper high level signal and the weigh hopper load cells. This, of course, does not include the operator touchscreen input. The mix hopper high level signal is generated by a proximity level sensor located in the right hand portion of the mixer chamber (viewing from the mixer door). Load cells require +10 volts DC to operate.
Chapter 6: Troubleshooting 6-1 Introduction The utmost in safety precautions should be observed at all times when working on or around the machine and the electrical components. All normal trouble-shooting must be accomplished with the power off, line fuses removed, and with the machine tagged as out of service. The use of good quality test equipment cannot be over-emphasized when troubleshooting is indicated.
Problem PLC Module Loaded Corrective action Normal after a software upgrade. Follow on-screen instructions. Check the input power. Verify that 110 volts (or 220 volts) are ±10%. This voltage must remain constant with all the motors starting and stopping. Insure that the blender is on a “clean” circuit that does not have other equipment on it. If the power is known to be intermittent and have problems, set up the unit to run in “AutoStart” mode. See the factory setup sheet at the end of this manual.
Problem Recorded Inventory Totals don’t match what I’ve actually used Max Hopper Weight Exceeded Alarm continues to re-occur. Blender occasionally dumps an incorrect batch. Blender keeps dumping after mixer is full. Blender will not batch with empty mixer. Bulletin Number Corrective action Check the blender’s scale calibration and verify that the batch hopper is not overfilling. If the hopper is overfilling, adjust your batch size.
Problem Mixer won’t shut off and runs continuously. Corrective action Check the Mixer and Dump Setup to see if the mixer is configured for “Continuous Mixing”. Set it to “Timed Mixing”. Check the value of the mixer timer setting. Check the value of the dump delay timer. Check the mixer motor fuse. This is located in the control panel on the SSR for the mixer motor.
Problem I can’t calibrate the Scale without an error message. I can’t calibrate the feeder without an error message. Corrective action This Is caused by the difference in bits not being large enough. Using the Direct Scale Readout, examine current loadcell bits with and without the calibration weight. If the bits do not change significantly, then check for pellets jamming the loadcells and check the loadcell circuit. You might have a bad loadcell.

7-5 Addendum (Service Supervisor Information) Note: This section of the manual should not be used by untrained personnel – blender controller and/or program can be compromised! Note: Hidden, programmable features and hidden menu pages should not be made available to floor operators. These pages include the Service Supervisor Information addendum located in this section.
Figure 66: Typical Engineering Only Setup Screen Go back to Setup Directory Factory Setup Menu Metering Test Screen This screen is useful in both R & D and development purposes when testing the metering performance of each feeder. The user can perform a “Single Meter by Weight” to evaluate the mechanical standard deviation of the gate or auger. This test meters for the calculated time based off the target weight entered on this screen.
This setting should not be modified except by the developer except under unusual circumstances. Figure 68: Typical Advanced Weight Options Screen Adjust the limit for “Hopper Over Max Weight” Weight Filter Weight/Sec. Filter Adjust Settle Go back to Engineering Only Directory Feed Algorithm Options Screen This screen allows the user to configure how the blender metering algorithm works.
Mechanical Options Screen This screen allows the user to change the number of hoppers, the predetermined gate cycle time, and the mixer bump time for detecting high level. The gate cycle time has been measured and set at the factory, but might need to be adjusted if we change the mechanical design of the gate, solenoids, and air cylinders. This setting will vary depending on whether you are using a gate or an auger.
Customer Setup Menu Units This screen allows the user to change the blender’s unit of measurement. The entire blender can be configured in either Kgs. or Lbs., while the Target vs. Actual data can be configured for either regardless of the blender’s units. Figure 73: Typical Units Screen Change Blender’s Units Change Target vs. Actual Units Go back to Setup Directory Network Setup This screen allows the blender to be configured for use with the Ethernet Option.
Alarm Setup This screen allows the user to configure the feeder type for each feeder; configure whether a feeder will retry during the metering of a batch, and enable or disable the “Out of Material” alarm for any feeder. If a hopper is set to “No Retry” then the blender will continue to meter the rest of the batch even if this hopper runs out of material.

7-6 Mitsubishi Communications Manual The Mitsubishi blender uses a FX-2N processor that communicates with the outside world using MELSEC FX protocol over Ethernet hardware. It’s Ethernet speed is 10 Mbits/second. The blender must be purchased from ACS with the Ethernet option. If this was not done at the time of purchase it can be added afterwards by consulting the factory.

Alarm Number Explanation: The alarms are given in individual bits and are reflected in the alarm number. The alarm number is only used to drive a pop-up message and will probably not be very useful to you.
WRITING RECIPE EXPLANATION To write a recipe you must first write to the “temp recipe” value locations above. After this is complete you should read the “accept recipe enabled” and the “recipe error” values. If you have a recipe error then you should display the appropriate text. If the “accept recipe enabled” is high then show a button that will then write to “accept recipe” bit. This will load in the recipe. You do not need to check the sum of the recipe that they’ve entered.
