ASSEMBLY AND INSTALLATION INSTRUCTIONS
The MGF consists of these assemblies:
1. The Adaptor Frame Assembly
2. The Bar Assembly (for the Controller).
3. The Controller
4. The Load Cell Assembly
5. The Auger Tube Assembly
6. The Hopper Assembly
MOUNT THE ADAPTOR FRAME
1. The ADAPTOR frame mounts directly to the throat under your current natural material hopper.
For proper ORIENTATION, consider the following:
• Orient the Auger Tube Assembly at 90° to the machine barrel.
• Clearance and ease of access for removing the hopper.
• Easy viewing and access to the controller.
• The feeder will hang from the side of the adapter that has the opening into the flow chamber.
2. Locate and drill the proper bolt patterns (top and bottom of the adapter frame). This frame will be bolted
directly to the feed throat of your process machine and the natural material hopper will be bolted on top.
The TOP plate has the ROUND hole.
The BOTTOM plate has the SQUARE hole.
MOUNT THE CONTROLLER
3. The CONTROLLER will be mounted to a bar that bolts on the left side of the adaptor frame. You may also
mount the controller in a remote location and use optional extension cords to connect the motor and load cell.
Be sure that the mounting screws are tight.
HANG THE LOAD CELL ASSEMBLY
4. Hang the Load Cell Assembly from the
side of the frame with the opening into
the chamber. (See photo) Tilt unit. (1)
Slip upper ear behind the corner post.
(2) Slip the lower ear behind the other
corner post. (3) Raise the lower ear up
and rest the load cell assembly into
frame as shown.
INSTALL AUGER TUBE ASSEMBLY
5. Insert the Auger Tube Assembly into Load Cell Assembly and hang onto the two bolt heads.
INSTALL HOPPER ASSEMBLY
6. Place the hopper assembly on the load cell assembly and secure with the hold downs.
PLUG IN ALL CORDS
7. Plug the motor and load cell cables into the Load Cell Assembly.
8. Plug the black power cable into a standard 120-volt (EURO, 230 VAC) outlet.

CONNECT SIGNAL CABLE
9. Standard equipped for contact closure applications only, your controller will be equipped with the supplied
cable lead and 5-pin connector. You will also have a 20’ length of cable with a mating 5-pin connector. This
cable will connect to the MGF controller using the connector, and the open end will be wired to your
equipment. The open ends leads should be wired to the screw signal normally open contact closure. When
the screw is retracting contacts will close and then open at the end of the retract. The time closed is used by
the MGF to adjust output. This 5-pin connector is also used with an extrusion following 0-10 volt signal.
See the MGF wiring diagram on page 41.
10. If optionally ordered with 24 to 120 VDC or VAC plug the "SIGNAL" (gray) cord will be plugged into outlet that
is energized only when the screw is turning. Signal voltage can be from 24 to 120 VDC or VAC. The screw
signal on-time can not be less then 1 second. INJECTION time or CLAMP CLOSE time are options.
Description of Controls
1. POWER ON / OFF SWITCH - Turns power on or off. Switch light
is illuminated when MGF is powered ON.
2. RUN / STOP SWITCH - This switch provides a run signal to the
circuit board. For the MGF feeder to run, a screw turning signal
MUST be present, providing power to the screw signal cord, AND
the RUN switch must be in the RUN position. The only exception
is when the PRIME feature is selected. This will operate the auger
without any Run signal.
3. KEYPAD – Used to enter, modify data and settings. Arrow keys
are used to navigate screens. The Enter button selects menu
options and the Back button cancels or takes you back one step.
The View button displays totals, cycles, date and time with the
option to clear totals and cycles by pressing 00 to clear. Pressing
any non-zero number will cause the controller to write totals to a
USB key. There must be a folder named "maguire" on the USB
key for the print job to write the file printer.txt within that folder.
The i (info) button displays the diagnostics screen with real-time
data and averaged and target data. See page 35 for more details
on the diagnostics screen.
