ASSEMBLY AND INSTALLATION INSTRUCTIONS Your unit consists of 4 separate assemblies: 1. 2. 3. 4. ADAPTOR frame assembly; 10" square, painted black. SLIDE assembly; stainless steel. HOPPER assembly; with feed auger. CONTROLLER / Drive unit. 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. Bolt the CONTROLLER to the motor mount...

START-UP INSTRUCTIONS Plug the "CONTINUOUS POWER" cord into a standard 110 volt continuous power source. Plug the "SIGNAL" cord into outlet that is energized only when the screw is turning. Signal voltages from 24 to 240 can be handled. Set the CYCLE/OFF/CONTINUOUS switch to "CYCLE". Follow instructions on the FORMULA page to determine the METERING RATE for your regrind. Then, using the formula provided, set the counter to the proper setting for the particular part you are molding. Select the PERCENT REGRIND that you desire by setting the small rotary knob to the proper "%" setting (5-80%). Set...

PRINCIPLE OF REGRIND CONTROLLER OPERATION The MAGUIRE Digital Controller provides the precise speed regulation and metering control necessary to assure absolute accuracy over regrind 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 regrind 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...

ADDITIONAL INFORMATION - REGRIND CONTROLLERS All REGRIND controllers are equipped with a "PERCENT SELECTION" knob, Regrind LEVEL sensor, and two electrical outlets mounted into the back of the controller housing. The PERCENT SELECTION knob allows an operator to rapidly select or change the PERCENT of regrind that he wishes to add. Since the COUNTER setting represents a quantity of regrind equal to the FULL WEIGHT of the molded part, the PERCENT knob will automatically reduce this number to the percentage of regrind that is actually requested. The L.E.D. DISPLAY will show the reduced number and...

PRINCIPLE OF REGRIND FEEDER OPERATION The MAGUIRE CONCENTRATE AUGER FEEDER is a rugged industrial auger feeder designed to meter precise quantities of color concentrate very accurately into the main flow of virgin material directly above the throat of your process machine. Two 10" square steel plates, separated by 4 steel corner posts, form a sturdy, low profile, adaptor assembly. This assembly must be drilled with the proper bolt pattern and then mounted to the throat of your process machine where the main material hopper is currently mounted. The material hopper is relocated on top of the adaptor...

CYCLE-OFF-CONTINUOUS SWITCH CYCLE: The controller will meter a given quantity of regrind and will shut off for the remainder of the cycle. Quantity metered is controlled by the setting of the thumbwheel switch. In this mode, motor speed is automatically adjusted by the internal microprocessor based on the time length of the previous cycle and the setting of the counter. A speed is selected that will allow the feeder to stop approximately 1/2 second before the cycle ends. OFF: Prevents the controller from running and removes power to the computer controls. CONTINUOUS: The controller will run continuously...

appearing between the middle and last digit. Display format will be (##.#) so that fractional numbers can be set on the counter. A maximum of about 10 turns will result from the maximum setting of 99.9. Thus, to accomplish the same output as before, you would use a setting such as 030 instead of 003, resulting in a display of "03.0" instead of "003". CONTINUOUS MODE: no effect CALIBRATION (right position) CYCLE MODE: The term "calibration" in not correct for this position. On regrind style controllers this position is for LOW RESOLUTION. This is the opposite of the FRACTIONAL position described...

ADDITIONAL REGRIND CONTROLS PERCENT (%) SELECTION KNOB The PERCENT knob must be set to the "%" of regrind that you desire. Since the counter setting represents the full requirements of the process machine (as if you were going to use 100 percent regrind), the "%" knob will reduce this setting to whatever percent you select. For EXAMPLE: if your counter is set to 400, and the "%" knob is set to 25%, then the count will begin at 100 (25% of 400) and will count down from there. 9. The SENSOR is to be installed into the sensor MOUNTING socket located on the side of the hopper. This will signal the...

FORMULAS FOR SETTING THE COUNTER REGRIND FEEDERS INJECTION MOLDING (Cycle Mode): 1. Determine the WEIGHT of the entire shot IN GRAMS. 2. Determine the METERING RATE in "grams/100count" of your regrind. 3. Set the digital counter using the following formula: (shot wt) / (grams/100count) x 100 = Setting ============================================ Example: Shot Weight = 100 grams Metering Rate = 80 grams/100count 100 / 80 x 100 = 125 EXTRUSION (Continuous Mode): 1. Determine the extruder output in pounds per hour. 2. Determine the METERING RATE in "grams/100count" of your regrind. 3. Set the digital...
