General InformationLow Level Proximity SwitchesThe adjustable low level proximity switches aredesigned to stop the metering pump when the materialin either pail runs low. The proximity switches are to preventthe machine from pumping air into the materiallines. When the ram is lowered and the fault cleared, thepump can be restarted.Platen - Colorant Tank (Optional)The platen is recommended for materials that are notpourable or self leveling. There is a small plastic platenshipped with each colorant tank. If the colorant is inpaste form, the platen is placed on top of the colorantand should be removed BEFORE filling the tank. If thecolorant that is being used flows easily the platen shouldnot be used because it will sink and block the tank outlet.SolventsThese are rarely used with modern 1:1 silicones. Forcleaning, methylene chloride or white spirits solvent areused. Methylene chloride is recommended because it isnon-flammable.To avoid serious injury, do not use flammablesolvents for cleaning.332312A 9

Screen IdentificationScreen IdentificationMode Select ScreenThe “Mode Select” Screen is the default screen on startup. It can be used to select an operating mode, control colorinjection, and navigate to other screens for setup and operation.The different modes can be used to:• Dispense material while monitoring the ratio• Take a sample ratio• Prime the pumps• Purge Material• Transfer material to another unit• Bring the pumps to their home positionNOTE: Refer to Schematics, page 41, for customer signal information.IconDescriptionExplains how to use the Mode Selections and the Color Injectors on the screen.Brings the pumps back to their home position. Pressing the “Start Pump” button on themonitor screen turns the pumps on. The machine will alert the user when in the eventthat it needs to be “rehomed.”Main dispensing mode. It will dispense material at a specified ratio as long as the “ScrewRotate Signal” is active. Pressing the “Start Pump” button on the monitor screen willallow the machine to look for that signal. The “ready” signal will activate in this modewhen the start pump is pressed.This mode will vary the ratio by a maximum of 5% to get the pails to empty out at thesame time. It is not attempting to maintain a 1:1 ratio. It will dispense material at a rationear 1:1 as long as the “Screw Rotate Signal” is active. Pressing the “Start Pump” buttonon the monitor screen will allow the machine to look for that signal. The “ready” signal willactivate in this mode when the start pump is pressed. Always check with the materialsupplier to verify material tolerances prior to using this mode.Purge Mode operates only one pump at a time. The button purges the injection and manifold/mixerassemblies with a single component of material. Contact your material supplierto determine which material is best for purging. Press the “Start Pump” button onthe monitor screen to allow the machine to operate. It will purge as long as the “ScrewRotate Signal” is active.14 332312A

Screen IdentificationIconDescriptionBefore starting to prime, decrease the regulated air pressure to 20 psi (140 kPa, 1.4 bar)- Reducing the pressure prevents pump cavitation. Increase as needed. Refer to Purgeand Prime the Pump, page 28, for details on purging the machine. The pump will startoperating as soon as the “Start Pump” button is pressed on the monitor screen once themode is allowed.Intended to check the ratio of the machine. The outlet valves will not open and faults willnot be generated. To check the ratio, refer to Ratio Testing, page 36. The pumps willactuate as soon as the “Start Pump” button is pressed on the monitor screen.Transfer Mode allows both pumps to operate independently. Typical applications for themode are for filling small cartridges individually or feeding the 600 series metering units.The pumps are active as soon as the “Start Pump” button is pressed on the monitorscreen.Navigates to the “Monitor Screen”.Navigates to the “Main Screen”.Navigates to view the alarm history of the machine.Toggles the color injector for the corresponding machine (1 or 2) on or off. The injectorworks with the “System Ready Bit”, and operates under the parameters on the PresetScreen.This is a banner that tells the user what mode the machine is in.This is a button that goes to a screen showing the software part numbers and revisions.332312A 15

Screen IdentificationMonitor ScreenThe “Monitor Screen” will be used most for dispensing material. Most of the fields on here are for feedback only. Thebottom row of buttons are used to navigate to other screens, while the buttons on the right side are used to controlthe pump.IconDescriptionDepending on what mode the machine is in, the button will either start the pump immediatelyor allow the pump to run and look for a “Screw Rotate Signal” to start pumping.Stop the pump from operating.Navigates to the “Main Screen”.Navigates to the “Mode Select Screen”.Meter Mode:The amount of travel for a pump can be regulated from 50-100% of its potential travel. Forexample: One pump may travel at 50% of its full capability while the other pump is traveling at100% capability. The system would be operating in a 1:2 ratio. This shows the preset percentageand the actual percentage of pump travel.Closed-Loop Mode:The actual percentage may vary from the preset by +/- 5%, which is always a 1:1 ratio.Always check the material supplier to verify material tolerances prior to using this mode.Some materials (self-bonding or self-bleeding grades) should not use this mode since atighter tolerance is needed.This field shows the position of each pump, and if they are moving in the up or down direction.This shows if the injector is on or off, and what percentage of colorant is making up the totalmixed material volume.This shows how many kilograms of material are left in the container.16 332312A

Screen IdentificationMain ScreenThe top row of buttons requires a password, the bottom row is accessible without a password. To enter a password,simply touch the blue box, and a keypad will appear. The default password is 0. Refer to the Presets Screen screen,page 20, for information on how to change the password.IconDescriptionThis screen allows the user to set how far the pumps are allowed to deviate from each other beforean alarm is set off. It also allows the user to set how many seconds the alarm sounds for, as well asto change the password.The system preset screen allows for configuring the HMI panel, and setting the communicationbaud rate.The preset screen gives access to the color injection properties, mixed material specific gravity,machine ratio, material container size, and pail monitor settings.The mode screen select gives control of the color injection system, and allows the user to changemodes of the machine.Navigates to the “Monitor Screen”.The I/O Table screen shows the user what inputs and what outputs on the PLC are active.332312A 17

Screen IdentificationFault Presets ScreenThe Fault Preset screen allows the user to:• Configure when errors are generated• Configure how long the alarm sounds for• Access to change the passwordThe Upstroke and Downstroke values are represented by encoder counts. The larger the number, the greater thespacing allowed before a fault will occur. For example, there are 30,000 counts in the 4.5 in. (11 cm) pump stroke, sothe default tolerance is a 0.45 in. (1 cm) difference. The default value is 3000.Each pump has its own presets to generate alarms. For example, when both pumps are traveling down, the A sidecan travel faster the B side by X amount, and the B side can travel faster the A side by Y amount. The same conceptapplies to traveling up.IconDescriptionExplains what the Pump Stroke Fault Presets represent and how to use them.Measured in encoder counts. This is how much further a specified pump may be travelingahead of the other pump in the up direction. For example, “A” Upstroke is how far the A pumpcan be ahead of the B pump when traveling up. The default is 3000.Measured in encoder counts. This is how much further a specified pump may be travelingahead of the other pump in the down direction. For example, “A” Downstroke is how far the Apump can be ahead of the B pump when traveling down. The default is 3000.This is how many seconds the alarm will sound when a fault is detected.Entering a password in this field changes the password for accessing protected screens.“On” disables any faults related to the color injector frequency from being generated.“Off” monitors the color injector for too few shots (uneven color) or too many shots per secondwhere the color injector will not be able to refill properly.18 332312A

Screen IdentificationSystem ScreenThe System Preset Screen allows the user to change the baud rate of the HMI communication. This adjustmentwould be needed if a replacement HMI was being installed on legacy equipment.IconDescriptionGives access to the HMI panel configuration. It is rare that normal machine operation will requireaccess to this.The PLC communication baud rate. The default is 19200, legacy PLCs communicate at 9600.332312A 19

Screen IdentificationPresets ScreenThe Preset Screen allows the user to make adjustments to settings directly related to dispensing material:• Color Injector Percent• Color Injector Shot Size• Mixed Material Specific Gravity• Machine Ratio• Pail Monitor SettingsIcon DescriptionPercent of color to be injected with the amount of material being dispensed. There are separateeditable boxes for colors 1 and 2. If the entered value is too small, the field will turn yellow.Size of the shot being dispensed by each color injector. The shot size is adjustable mechanically,so test the shot size of each color individually. Refer to Adjust the Colorant InjectorShot Size, page 30.The Specific Gravity of the mixed material. Refer to the material data sheet supplied by thematerial manufacturer.How far the pump will move out of its total capacity. For example 50% A and 100% B wouldtranslate roughly to a 1:2 ratio.Set to a 5 gallon machine configuration. It changes how the machine interprets how muchmaterial is left and should only need to be set once.The K-Factor describes how the string pot behaves when it reads the platen's position. Theunits are millivolts/volt/inch and is listed on each device.The offset applies to the pressure transducer and string pots. To calculate an offset, performString Pot Calibration, page 40.Observable field only. It is showing the sensor value after the calibration calculations havebeen performed.20 332312A

Screen IdentificationAlarm History ScreenShows a history of the alarms generated by the machine.System IO ScreenShows what inputs and outputs are active on the machine.Information ScreenShows the PLC and HMI program numbers.332312A 21

Screen IdentificationWarning ScreensA warning alerts the user that the machine may need adjustments to produce better results. The following are potentialwarning screens that may appear:If equipped with a material level sensor on the color reservoir, the warning will indicate that the material level is low. Ifthe warning has never been generated before the machine runs out of colorant, the low level sensor may need to berecalibrated.Recalibration: With the material empty, press the “Empty” switch on the low level sensor. Refer to the low level sensormanual that was provided with the machine to ensure the correct switch is pressed.This warning is generated if the percentage is too low, causing a shot spacing that is greater than 13 grams afterpressing the start pump button. Refer to Adjust the Colorant Injector Shot Size, page 30. After the shot size hasbeen changed, the new shot size will need to be determined and entered on the “Preset Screen.” This will cause themachine to take more shots to achieve the same color %. Another option is to increase the color % so the machineinjects more frequently. Rate is determined by “A” and “B” flow rate.22 332312A

Screen IdentificationFault ScreensA fault is a type of error that stops the machine from operating. The following are potential fault screens that mayappear:These screens indicate that a material low level condition has occurred. This usually indicates that the material pailsneed to be changed. The low level indicators are adjustable to ensure as little waste as possible. Refer to PailChange-Over, page 34, for material changeover procedures. If the fault condition still exists after the “AcknowledgeFault” key is pressed, the alarm and fault screen will activate again. This will prevent an accidental reset withoutchanging the pails.The color injector is designed to dispense the entire contents in about 0.2 seconds. This depends on the air pressuresupplied to the color injector. The refill time is approximately the same as the dispense time. It also relies upon the airpressure supplied to the unit. The message will be generated when a shot size is too small. Refer to Adjust the ColorantInjector Shot Size, page 30.The pump listed in the screen title has traveled past the other pump by X amount of encoder counts in the downwarddirection, as defined on the Fault Preset Screen. This fault indicates that there is a problem with the pneumatic circuitthat allowed the pump to relax. When the pump is waiting for the activation signal from the injection mold machine, allof the valves are in the locked-center position, locking pressure inside the pumps for the next cycle.332312A 23

Screen IdentificationIn the event that the machine needs the pumps to be rehomed, this screen will appear. Navigate to the Mode Selectscreen and select Rehome Mode to place the pump in the home position. The rehome sequence will not begin untilthe pumps have been activated on the Monitor Screen.24 332312A

Refer to the material supplier to determinewhich material is best for purging. Usually theywill recommend the “B” material to flood the mixerwith inhibitor.2. Press the “Start Pump” key on the monitor screen.3. Activate the “Screw Rotate” signal on the press tostart the pumping system.Shutdown1. Perform Base Purging procedure.2. Perform Pressure Relief Procedure, page 33.3. Press the “Stop Pump” button on the “MonitorScreen.”4. Rotate the ram control valve to the “LOCK” positionas shown.4. Pump enough material to fill the static mixer andbarrel assemblies.NOTE: If a color injector is installed, color will not flowduring a purge cycle. A visual indication will occur whenthe single component begins to flow out the nozzle.5. Purge material on the outside of the mold. Continueto purge until the material does not cure.NOTE: If the machine will be shutdown for a period longerthan the pot life of the material, remove all assembliesthat contain mixed material and clean thosecomponents.NOTE: If the ram control valve is set to either the “UP” or“DOWN” position, the pail shelf will fall downward.5. Press the stop button on the front of the machine.32 332312A

Pressure Relief ProcedurePressure Relief ProcedureThis equipment stays pressurized until pressure ismanually relieved. To help prevent serious injury frompressurized fluid, such as skin injection, splashingfluid and moving parts, follow the Pressure ReliefProcedure when you stop spraying and beforecleaning, checking, or servicing the equipment.There are two ways to relieve pressure of the system.Dispense Head SolenoidPerform the procedure if the dispense head can flowmaterial freely.1. Press the “Stop Pump” button the “Monitor Screen”while the machine is energized and the controlpower button is illuminated.Bleed Ball ValvesPerform the procedure if the dispense head is pluggedor there is no air to actuate the dispense head solenoid.1. Press the stop button on the front of the machine.2. Place a waste container below each Bleed BallValve.3. Open both Material Ball Valves.2. Open both Material Ball Valves.3. Press and hold the solenoid override button to openthe dispense valve for the “A” material side.4. Release the solenoid override button once the analogpressure gauge reads 0 psi.5. Repeat steps 3 through 4 for the “B” material side.“A” SolenoidOverride“B” SolenoidOverrideIn the following step, any pressure in the lines will beinstantly relieved if no obstructions are within thelines. This may lead to material spraying out of thevalve and splashing in the bucket. Use appropriateprotective wear to prevent contact with materials.4. Open the “A” Bleed Ball Valve. Residual pressurewill be relieved in the fluid lines between the pumpand the check valve.5. Verify the analog pressure gauge reads 0 psi.“A” MaterialPressure Gauge“B” MaterialPressure Gauge“A” MaterialPressure Gauge“B” MaterialPressure Gauge6. Repeat for the “B” Pump Bleed Valve.332312A 33

OperationOperationPail Change-OverExcessive Ram air pressure in the material pail couldcause the pail to rupture, causing serious injury.Ensure that the pressure settings are set to the recommendedair pressure. Refer to Pressure Settings,page 8.1. If the machine is equipped with the color option,refer to Fill the Colorant Tank and Prime theColor Injector (Optional), page 26.2. Calibrate the string pots if required. Refer to StringPot Calibration, page 40.3. Turn the Ram Control Valve to the DOWN positionand let the air escape from the Ram Air Cylinders ifa pail is installed.5. Lower the Pail Shelf to its minimum height.6. Clean the bottom of the platen with a flat, non-metalscraper.7. Load the new pail into the machine, paying specialattention to put the “A” material on the “A” side.NOTICEFailure to separate chemical components will result inthe curing of material in the pumps and hoses.NOTICETo avoid cavitation and component interference, installthe pail on the pail shelf so that the handle of the pailwill not interfere with the ram during normal machineoperation.8. Apply a small amount of lubricant to the platen sealto aid the installation. Use a small amount of materialif a lubricant is not available.9. Open the Bleed Ball Valve on the platen hub.Activating the blow-off button prior to reaching 30 psi(210 kPa, 2.1 bar) of Ram air pressure may result inserious injury. Activate the blow-off button only whenthe pressure reaches 30 psi (210 kPa, 2.1 bar) orbelow.4. Press the blow-off button to push the pail and shelfoff the platen.34 332312A

Operation10. Set the Ram Air Regulator to 5 psi (35 kPa, 0.3 bar).11. Turn the Ram Control Valve to the UP position toraise the Pail Shelf to the platen.12. Slowly increase the Ram Air Regulator to the operatingpressure.NOTE: If your pails have liners, use special care not topush them down into the pail with the platen.NOTICETo avoid cavitation and machine damage, the RamControl Valve should be left in the UP position whilepumping.NOTE: Once the platen enters the pail, air and materialwill exhaust out the ball valve on the platen hub. Allowthe silicone to flow until it is free of bubbles then closethe ball valve.13. Repeat the Pail Change-Over procedure to loadthe material pail for the other side.332312A 35

Testing ProceduresTesting ProceduresPump TestingIf the machine is suspected of pumping inaccurately, followthese procedures to check each pump.At normal operating pressure, test if the pump is leakinginside, which will cause one pump to run faster than theother. Follow these steps.1. Close the both Material Ball Valves on the top of theunit.2. Select “A-Prime” to test the “A” pump.3. Press the “Start Pump” button on the monitorscreen to begin pumping.Ratio TestingNOTE: Run at least three samples to ensure a goodrepresentation of the pumps output and have collectedsamples from both the up and down strokes of thepumps. Take the average of these weights before calculatingthe actual ratio.1. Turn on the Main Air supply and press the controlpower button.2. Set the Ram Air Regulator to 20 psi (140 kPa,1.4 bar)3. Verify the Pump Bleed Valves and the Material BallValves are closed on both the “A” and “B” pumps.NOTE: Pressure inside the pump should build up causingthe pump to stop moving.4. Test the pump in both directions using the BleedBall Valve on the metering pump as an outlet.NOTE: If the pump continues to move in either directionand all the outlet valves are closed, the pump may beleaking internally.5. Refer to Troubleshooting, page 38, for possiblesolutions to pump leakage.6. Repeat steps 2 through 5 for pump “B” using“B-Prime” mode.Pump BleedValve4. Navigate to the “Preset” screen. Verify both pumpsare set to 100% of stroke.5. Navigate to the “Mode Select” screen and select“Ratio Sample”.6. Navigate to the “Monitor” screen and select the“Start Pump” button which will activate the pump.36 332312A

Testing ProceduresNOTE: Other modes require the “Screw Rotate Signal”from the injection molding machine to activate the pump.Ratio Test Mode does not require this signal and thepump will ignore most of the fault conditions to allow theuser to test the system. The material outlet valves willremain closed to ensure the entire sample is being dispensedout through the ratio sample valves.7. Open the Pump Bleed Valves located at the top ofthe pump and collect material until the air has exitedthe valves using two waste cups. Close the valveswhen finished.8. Weigh two empty cups and record the weight andmaterial side on the cup for easy access to thisdata.9. Open the ratio sample valves at the same time andcollect all of the material being pumped out for atleast two full pump cycles using the cups weighed inthe previous step.NOTE: The larger the sample taken, the more accuratethe sample will be.10. Close both of the ratio sample valves at the sametime once the sample has been collected.11. Weigh both cups and subtract out their originalweight. This remainder is the weight of material thathas been dispensed.12. Substitute the weights into the following formula toget the ratio in the form of A:B.A:B(Calculated Ratio = B Weight):1A Weight13. Adjust “percent of stroke” on the “Preset” screen asneeded to achieve the desired ratio.14. Repeat steps 7 through 11 to verify the ratio is correct.332312A 37

TroubleshootingTroubleshootingBefore performing any troubleshooting procedure:1. Perform Pressure Relief Procedure on page 33.2. Press the Stop Button.3. Remove air supply.4. Allow the press equipment to cool.Try the recommended solutions in the order given foreach problem to avoid unnecessary repairs. Also, determinethat all circuit breakers, switches, and controls areproperly set and wiring is correct.Common ProblemsProblem Cause SolutionUp-StrokeIf the pump continues tomove in the up direction afterall of the outlets have beenclosed, check the followingareas.Air in the MaterialAir is the most common cause of up and down-strokeerrors. Therefore, the Pump Testing procedure,page 36, should be performed a couple of times toensure the pump is void of air. An indication of air inthe pump can be seen when the pump changes directionsfrom the up-stroke to the down-stroke. If air ispresent, the pump will jump or move more rapidly inthe down direction and then begins to move slowlywhen it hits the material. To remove any air from thepump, refer to Purge and Prime the Pump, page 28,and then repeat the test again.Piston Ball CheckThe ball seat at the end of the pump piston may haveforeign material lodged in the seat preventing the ballfrom seating properly. Over time, the pressure ofabrasive silicones can damage the piston seat or pistonball requiring it to either be replaced or repaired.Careful inspection of the piston seat should be takenevery time the pump is disassembled.Piston SealThe Piston Seal prevents material leaking around thePiston during the up-stroke cycle. Piston Seal failurecan be caused by extended use or from a roughPump Cylinder wall.Pump CylinderA worn or galled cylinder wall will allow material toflow by the Piston Seal causing the pump to creep inthe up direction. Prolonged use in this state will causepermanent damage and introduce foreign object intothe chemical.Upper Rod SealThe Upper Rod Seal prevents material leaking aroundthe displacement rod. Upper Rod Seal failure can becaused by extended use or from a rough displacementrod wall.38 332312A

TroubleshootingProblem Cause SolutionDown-StrokeIf the pump continues tomove in the down directionafter all of the outlets havebeen closed, check the followingareas.Shovel Rod SealCheck Plunger (B443 Pump)Up-Stroke andDown-StrokeIf the pump fails to dispenseany material in either directioncheck the followingareas.Intake AssemblyShovel AssemblyThe seal separates the cylinder from the shovel platehousing. If it fails, material will be forced into theshovel plate housing during the down-stroke.The check plunger is controlled by a pneumatic valveinstead of material pressure. Shaft wear, plunger failure,or seat/seal damage could allow material to backflow into the pail or out the weep holes on the intakeblock.The device opens on the up-stroke and closes on thedown-stroke. It is controlled by material pressurepushing down on a ball against a seat. If either ofthese devices fail the pump will not work properly. Thesymptoms of an Intake Assembly problem can rangefrom partially cured parts (due to cross contaminationof the system) to no material on either stroke of thepump.The shovel and shovel plate work together to pullmaterial from the pail into the pump. The shovel platerises on the down-stroke so material can flow throughthe holes in the Shovel. On the up-stroke the shovelplate closes forming a seal with the Shovel that forcesmaterial into the pump housing. If either of these componentsare working improperly, the pump would failto load and dispense material.332312A 39

TroubleshootingString Pot CalibrationThe string pot may need to be calibrated if a low levelsensor has been activated but the amount of materialshown on the “Monitor” screen shows that there is materialstill in the pail.j. Clean the platen of any debris before installing anew pail.a. Verify the K-factor on the “Preset Screen”matches the K-factor listed on the string pot’slabel. The K-factor on the label is called “PosSens” and has the units mV / V/ Inch.b. Place a 1 in. board between the pail shelf andthe platen for the side being calibrated. Raisethe pail shelf to the platen and board.NOTICETo avoid cross contamination, use a new 1 in.board.c. Disregard the low level sensor warning if it isgenerated.d. Press the Stop Button on the front of themachine to deactivate the low level sensor.e. Enter “0” for the offset.f. Read the “Actual” value on the “CalibrationScreen”.g. Enter the “Actual” value into the “offset” field toobtain a “0” reading for the “Actual” value shownon the screen.h. Lower the pail shelf.i. Repeat for the other component.40 332312A
