ASSEMBLY AND INSTALLATION INSTRUCTIONS Your unit consists of 4 separate assemblies: 1. 2. 3. 4. ADAPTOR frame assembly (10" square). SLIDE assembly. HOPPER assembly. 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 portion of the SLIDE assembly, utilizing the bolts...

CONCENTRATE FEEDER ASSEMBLY PICTURE

SET UP INSTRUCTIONS - EXTRUSION FOLLOWING CONTROLLERS 1. must be plugged into any 110 volt continuous power The RPM tachometer feed line provided must be installed from the extruder to the controller. On the extruder, this line must be connected to the tachometer output (either AC or DC) which drives the RPM gauge. CALIBRATION OF ELECTRONICS - (required one time only): Calibration is necessary to match feeder electronics to the particular voltage output of your extruder. In the upper right corner of the front of the controller, there is a small access hole. This provides access to a small trim...

If you have calibrated your unit properly, the following should occur: Display number -------------Setting number Current extruder speed ---------------------Maximum extruder speed At FULL SPEED, number displayed will EQUAL Counter setting. At HALF SPEED, number displayed will be HALF of setting. At REST, (O voltage) number displayed will be 0. IF the controller continues to run and display a number when no extrusion voltage is present; recalibrate the electronics as follows. Repeat low tach voltage calibration steps 1 and 2 above this time setting the controller to 500 instead of 100. This means...

FORMULA FOR SETTING THE COUNTER EXTRUSION FOLLOWING CONTROLLERS 1. Determine the MAXIMUM extruder output in pounds per hour, (at 100% of full rated RPM), (max lbs/hr). 2. Determine the POUNDS per 100 of color required (lbs/100). 3. Determine the color METERING RATE; GRAMS / MIN @ display of 40; (gr/min@40), see below. 4. Set the digital counter using the following formula: (max lbs/hr) x (lbs/100) x 3 / (gr/min@40) = Setting x15 for low voltages ==================================================== Example: Extruder output = 900 pounds per hour lbs/100 required = 4.5 METERING RATE = 130 gr/min@40...

PRINCIPLE OF CONTROLLER OPERATION EXTRUSION FOLLOWING Controllers equipped with our EXTRUSION FOLLOWING option differ from our standard controllers in several important ways. 1. A "CYCLE" power cord is not provided. Instead, an extruder speed signal cord is provided to carry the extruder RPM tachometer voltage to the controllers computer logic. The color controller then follows this signal exactly as extruder RPMs and related tachometer voltages change. An additional calibration adjustment must be made to allow the controller to function properly for the particular voltage range and output characteristics...

ADDITIONAL CONTROLLER INFORMATION The MAGUIRE Digital Controller provides the precise speed regulation and metering control necessary to assure absolute accuracy over color usage. 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 is designed to do this with precision. Our standard Model divides each full motor rotation into 159 increments; each increment representing a small fraction of a gram of color being carefully measured out. The digital...

PRINCIPLE OF CONCENTRATE 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 3" high 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...

DESCRIPTION OF CONTROLS and OUTPUTS 1. FOLLOW-OFF-MANUAL SWITCH EXTRUSION FOLLOW: The controller will follow the speed of the extruder based on the voltage signal that it receives from the extruder into the special receptacle located on the back of the controller. OFF: Will prevent the controller from running and will remove power to the computer controls. If a voltage spike or transient power surge should cause the processor to become "confused", switching to OFF may be necessary to re-start the processor. MANUAL: The controller will run continuously as long as 110 volt power is present at the...

If a loader is in use, remove pickup line from the color container and allow to 'dry' cycle one time to clear the line. Turn loader off. A locking latch is located on each side of the Color Feeder. Lift these latches up and rotate them forward until they fall freely forward to a straight down position. Slide the controller-drive unit straight back until inches). There is no need to turn the controller off. Slide the hopper and auger assembly back a few inches. Grasp the hopper handle in one hand, and with the other hand under the back side of the hopper, lift straight up and back. Dump the unused...

TROUBLESHOOTING CONTROLLER PROBLEMS IF YOUR MAGUIRE PRODUCTS CONTROLLER DOES NOT WORK PROPERLY: 1. READ below about NORMAL OPERATION and compare to your problem. 2. The QUESTIONS that follow may assist you in solving your problem. 3. If you are unable to remedy the problem: a. ANSWER in writing as many of the QUESTIONS that apply. b. DESCRIBE the PROBLEM in your own words as carefully as you can. c. RETURN this information with the unit for repair. NORMAL OPERATION With MAIN POWER cord plugged cord, Switch on FOLLOW: NO voltage to the signal following The display should read zero ( 0) The motor...
