ASSEMBLY AND INSTALLATION INSTRUCTIONS Your unit consists of 4 separate assemblies: 1. 2. 3. 4. The ADAPTOR frame assembly; 10" square, painted black. The SLIDE assembly; stainless steel. The HOPPER assembly; with feed auger. The CONTROLLER / Drive unit. 1. A locking latch is located on each side of the SLIDE assembly. Lift these latches up and rotate them forward until they fall freely. Grasp the heavy steel cross bar in one hand and with your other hand slide the motor mount frame straight back until it stops (5 inches). Lift the HOPPER assembly up and out and put aside. 2. Bolt the...

Series MPF® CONCENTRATE FEEDER ASSEMBLY PICTURE

START UP PROCEDURE 1. Plug the "CONTINUOUS POWER" (black) cord into a standard 120-volt continuous power source. 2. Plug the "SIGNAL" (gray) cord into outlet that is energized only when the screw is turning. This SIGNAL outlet will provide a voltage signal to an internal electronic relay. Signal voltages from 18 to 250 can be handled. For more information about the signal that you must provide, see "SIGNAL SPECS", below. The main switch should now be set on "CYCLE". The "screw return", or "SIGNAL ON" time, must be at least one (1) second. If you are not sure that this is always the case,...

NORMAL OPERATION The following is what to expect during normal operation. With MAIN POWER cord plugged in, NO power to the SIGNAL cord, Switch on CYCLE: The display should read zero ( 0) The motor light and signal lights are OFF The motor is NOT running. IN CYCLE: Nothing will run until the SIGNAL cord gets power. When the signal cord is powered, the signal light will be lit. The first time the signal cord gets power, the unit will start running at about 10 rpms and will count down starting from the number set on the counter. When the count reaches zero ( 0), the motor will stop. On all...

CYCLE TIME: The motor will start to run about 1/3 (.3) second after a signal is received. If the Signal is less than about 2/3 (.6) seconds long, then the motor will stop and the processor will NOT consider this as a valid cycle. No recalculation of motor speed will occur. If the signal is over 2/3 (.6) seconds long, then the motor will run for at least 2 seconds even if the signal goes away. This allows time for speed adjustments to occur. On longer cycles, over 2 seconds, the counter should count down to zero and the motor should stop within the 1/2 second before the end of the signal. If...

FORMULAS FOR SETTING THE COUNTER POWDER FEEDER INJECTION MOLDING (Cycle Mode): 1. Determine the WEIGHT of the entire shot IN GRAMS. This is the combined weight of the part or parts plus the runner, if any, that is molded each cycle. 2. Determine the POUNDS per 100 of color required. This is the pounds of color that you use for each 100 pounds of natural material used. 3. Determine the METERING RATE for each color in grams/100 counts. Metering rate is the weight in grams of color that is metered when the counter is set to 100. See the next page for instructions on determining Metering Rates....

DETERMINING METERING RATE Different colors have different bulk densities and different flow characteristics. To compensate for these variations and insure ACCURACY, a METERING RATE must be determined for EACH COLOR. 1. You may use a feeder mounted on a machine or you may remove it from its mounting frame and set it on a bench top. You may use one feeder to determine metering rate and apply this information to all feeders that are the same model, (i.e. same auger size and same gearbox drive motor). 2. Have the black power cord plugged in. The process machine does not have to run. The Gray...

PRINCIPLE OF CONTROLLER OPERATION The MAGUIRE Digital Controller provides the precise speed regulation and metering control necessary to assure absolute accuracy over color usage. The Controller signal cord is plugged into an outlet that is energized only when the process machine screw runs. During each screw return cycle, the motor runs and color is metered into the throat of the process machine. Since metering rate is directly related to motor output shaft rotation, accuracy is obtained by controlling the exact degree of rotation of the drive motor. The unique Maguire Products Digital...

CONTROLLER OPERATION IN CONJUNCTION WITH OUR REGRIND FEEDER All MAGUIRE Color Feeders are designed to work in conjunction with our REGRIND Feeder which may be purchased separately at some later date if the handling of REGRIND at-the-throat becomes a concern. This Regrind Feeder would be installed on the process machine at the base of the material hopper just above the throat. When used with our CONCENTRATE COLOR OR POWDER Feeder, the REGRIND Feeder adaptor frame would be mounted directly on top of our COLOR Feeder adaptor frame. The regrind would then enter the flow of virgin resin at the...
