Meter Mix PAR 3CM

overview dispenser the meter mix® par 3cm dispenser enables the use of carbon bulk resins in this course, you will learn unique to carbon operation of the par 3cm and reference the operator's manual for general use instructions refer to the operator's manual for specific operation of the par 3cm meter mix par 3cm product manual english safety please review all safety information in the docid\ ro9omdzmwxqpwohukmhy2 uncrating required equipment crowbar box cutter cart pallet jack or forklift process setup ensure that the crate is located at a safe distance away from sensitive equipment as there may be debris during the uncrating process move the crate using a hand pallet jack or forklift, if necessary remove screws from lid remove screws holding top lid in place, and remove the top lid power drill with screwdriver attachment is recommended for this and following uncrating steps remove screws from interior beams remove screws from the two beams across the top opening, and remove beams remove front wall remove screws from the front side wall pull the side wall down and out of the way remove plastic packaging remove the plastic packaging and straps holding the machine in place it is recommended to use a box cutter or similar cutting device remove remaining walls using a crowbar and hammer, remove the remaining side walls from the crate these are nailed together, and cannot be removed like the first wall using a screwdriver once removed, place these boards aside and away from heavy traffic areas because the exposed nails may pose an accidental safety hazard the machine is now ready to be moved to the location of use move the mmd with two or more people, carefully lift the machine onto a cart, or directly to the location of use, if convenient cart the machine to the desired location, and unload onto the final location it is recommended that the machine be placed on a flat and level surface strong enough to support its weight when full of material, and at a height which allows the operator easy access to all controls installation compressed air compressed air supply should be clean and dry at a minimum of 5 5 kgf/cm2 (80 psi, 5 5 bar) and a maximum pressure of 8 4 kgf/cm2 (120 psi, 8 bar) available air should be 5 cfm the minimum bore of the airline to the machine should be 8 mm turn the main main air pressure regulator up to 80 psi (0 55 mpa) turn the dispense dispense pressure regulator up to the correct setting for the resin being dispensed (see resin setting table) the knob needs to be pulled out in order to be adjusted, and pushed back in to lock it when the desired pressure is reached to prevent accidental adjustments in the pressure lower dispense pressures may be needed for lower viscosity resins to prevent violent shaking of the machine during use and unsafe dispense speeds during ratio checks consult the docid\ ro9omdzmwxqpwohukmhy2 below for recommended dispense pressures electrical in the united states, the mmd can be plugged directly into a standard 120 v outlet check that all wires are intact and functioning for example, the part a and part b tank refill sensors in the back of the tanks should each have a lit up led led inspect that the part a tank heater is functioning properly you should be able to set the tank temperature on the home display screen filling required before docid\ ro9omdzmwxqpwohukmhy2 or when the low level sensors indicate that the dispenser is low on either part a or b the frequency of this operation is variable, depending on the dispenser’s usage bulk resin container sizes vary from 5 l cans to 950 l ibc a full 20 l container weighs around 44 pounds (about 20 kg), and should be handled by two people one to position the spout over the tank and another to support the weight on the bottom of the container carbon recommends downpacking components into 5 l containers for easier handling position a short step ladder in front of the mmd so that the user can easily lift bulk containers to the top of the tank remove the tank lid pour part a or part b component resin from the bulk container into the appropriate tank until the desired level is reached replace the tank lid if the “fault active” alert is on due to low level a or b, press the blue reset button initial usage ensure tanks are filled with resin bleed air from the line if you suspect that there are air bubbles trapped before the dispense head, you may disconnect the hose from the dispense head, raise it high (air bubbles to travel up), and dispense use caution and follow safety guidelines from the operator's manual purge the lines if there was any liquid inside of the machine prior to receiving, purge the lines until there are no longer any remnants for example, epu 41 part b should be clear, and epu 41 part a should be the original consistency and color setting tank heating home screen from home screen press the set up button note tank a temp is shown from set up menu click on heating heating menu heating menu will show setpoint and actual temperature of part a note see docid\ ro9omdzmwxqpwohukmhy2 below for temperatures or contact mailto\ support\@carbon3d com change setpoint by entering value and pushing enter adjusting dispense ratio at all times when the pump is exposed and the panel is removed, for your safety it is recommended to disconnect the main compressed air supply this will prevent accidentally activating the pump during the manual adjustment process remove the four screws on top of the pump chamber and remove the panel using an adjustable wrench, loosen the lock nut on the piston rod while holding the top hat (the bronze colored junction) to prevent it from rotating, use an appropriately sized open end wrench to screw the piston rod either in or out of the top hat (see above image) turn the piston rod ¼ turn between each mass ratio check screw the part a rod into the top hat to bring the hardener forward screw the part a rod out of the top hat to bring the part a forward perform mass ratio check and inspect phasing repeat steps 3 and 4 until a satisfactory ratio is achieved both materials should also start pumping at precisely the same time use an adjustable wrench to tighten the lock nut on the piston rod apply threadlocker to the plunger rod and lock nut to prevent potential loosening replace the panel operation set operation mode there are two main modes of operation "metered shot" and "operator control" toggle between these by clicking on the mode name clicking on the mode name metered shot will dispense the specified amount of resin and stop operator control will dispense resin as long as "manual dispense" or the foot switch is pressed home screen set the resin amount in metered shot mode, set the amount of resin to be dispensed by clicking on the amount the amount setting dispense amount dispense resin in either mode, to begin dispensing resin click manual dispense manual dispense or activate foot switch to activate foot switch push lock mechanism lock mechanism towards back for switch step on switch step on switch to dispense maintenance when using for the first time in under 24 hours and the mix tip is already installed, run a burn off and proceed with normal usage swap out the mix tip if unused for over 24 hours when using a new mix tip, burn off 50 g daily wipe controls and screen with ipa weekly ratio check ensure lock nuts on piston rods are tight troubleshooting if the ratio measured during the ratio check is off, manually adjust the ratio using open end wrench observe the phasing if this is off, it is likely that the dispense ratio is off as well if nothing is dispensing during the cycle (the dispense pump is unable to move or dispense anything), there could be blockage in the line, blockage in the dispense head, or blockage at the non return valve (nrv) resin setting table resin recommended dispense pressure part a heating setpoint epu 41 80 psi 40 c rpu 70 50 psi 25 c
